For example, the head 520 may be connected to the sound wave vibration generating unit 510 and transmit the sound wave vibration transmitted from the sound wave vibration generating unit 510 to the body of a user in direct/indirect contact. Here, the head 520 may be made of various materials, such as a silicon material, a wood material, a plastic material, and a metal material, for example. The head 520 may transmit a stronger sound wave vibration to the user by locally transmitting the sound wave vibration to the user's body.

The lower plate 511 may be used to form a magnetic path of a magnetic field formed by the magnetic material 512 and the coil 514 .

A magnetic material 512 may be installed inside the lower plate 511 to be spaced apart from the lower plate 511 . For example, a groove in which the magnetic material 512 is fixedly installed is formed on the bottom surface of the lower plate 511, and the inner surface of the lower plate 511 may be spaced apart from the outer peripheral surface of the magnetic material 512 installed in the groove by a predetermined distance. .

The magnetic material 512 may be, for example, a permanent magnet that is a ferromagnetic material 512 such as a neodymium magnet. The magnetic material 512 may be used to generate attractive and repulsive forces when power is applied to the acoustic vibration module 500 and the coil 514 is magnetized to generate vibration. Here, the magnetic body 512 is located in the lower surface of the bobbin 513 and creates an efficient magnetic field, so that when the coil 514 wound around the bobbin 513 is magnetized, it generates mutual attraction and repulsion to generate stable vibration. can

The middle plate 515 may be installed on the magnetic body 512 to prevent loss of a magnetic field generated by the magnetic body 512 . For example, the middle plate 515 has a shape similar to the upper surface of the magnetic body 512 and is installed between the upper part of the magnetic body 512 and the lower part of the bobbin 513, and the magnetic force of the magnetic body 512 is the coil ( 514) can lead to concentration.

Here, the coil 514 is wound around the side surface of the bobbin 513 , and the coil 514 may be guided by an upper surface and a lower surface having a radius greater than a radius of the side surface of the bobbin 513 . Through this, the bobbin 513 guides the coil 514 to be stably installed on the outside, thereby preventing the coil 514 from being separated.

The bobbin 513 may be connected to the head 520 . For example, the bobbin 513 may be coupled to the head 520 through a coupling hole formed in the center of the upper surface.

The bobbin 513 may include a heat dissipation hole for dissipating heat. For example, the bobbin 513 may radiate heat generated when vibration is generated through at least one heat radiation hole formed in the upper surface, and reduce noise generated when vibration is generated together with a heat radiation effect.

The upper ring 516 is disposed on the lower plate 511 , and may be coupled to the first leaf spring 517 and the second leaf spring 518 . For example, the upper ring 516 may be coupled to the first leaf spring 517 and the second leaf spring 518 through a plurality of coupling protrusions formed on the upper surface. Here, the coupling protrusions may be coupled to dampers formed on the first and second leaf springs 517 and 518 . In addition, by supporting the upper and lower portions of the coupling protrusion coupled to the damper through an elastic member (eg, a silicone washer, etc.), it is possible to prevent vibration from being attenuated. The upper ring 516 can improve the durability of the sound wave vibration module 500 by forming a space in which the leaf spring can move up and down according to the characteristics of the generated sound wave vibration.

The leaf springs 517 and 518 may be installed on the bobbin 513 . For example, the leaf springs 517 and 518 are installed on the upper portion of the bobbin 513 , and act like a speaker to generate vibration when a sound source is applied. Specifically, the leaf springs 517 and 518 may generate sound wave vibrations in a vertical direction using a magnetic field generated by the interaction between the magnetic material 512 and the coil 514 .

The leaf springs 517 and 518 may be made of various materials suitable for generating sound wave vibrations. For example, the leaf springs 517 and 518 may be made of a metal material such as copper or STS 301 .

The leaf springs 517 and 518 may have a damper formed on the edge to maximize the vibration force. For example, the leaf springs 517 and 518 may include at least one damper having a shape extending in a radially curved band shape at an edge thereof, and having a coupling hole for screw coupling at an end thereof. Here, the dampers may be coupled to the coupling protrusions of the upper ring 516 through coupling holes. Of course, the shape of the damper is not limited thereto, and for example, the outer portion of the damper may have a circular structure, and the end of the damper may be disposed between fixing points.

The leaf springs 517 and 518 may include heat dissipation holes for dissipating heat. For example, the leaf springs 517 and 518 may radiate heat generated when vibration is generated through at least one heat radiation hole formed in the upper surface, and reduce noise generated when vibration is generated together with a heat radiation effect.

The leaf springs 517 and 518 may transmit the generated vibration to the outside. For example, the leaf springs 517 and 518 may be connected to the head 520 and transmit the generated sound wave vibration to the head 520 . Here, since the sound wave vibration generated in the center of the leaf springs 517 and 518 is the strongest, the sound wave vibration generated by being connected to the head 520 through a coupling hole formed in the center of the leaf springs 517 and 518 is applied to the head 520 ) can be passed to

The leaf springs 517 and 518 may be installed double on the upper portion of the bobbin 513 to improve durability. For example, the first leaf spring 517 and the second leaf spring 518 may be installed overlapping each other on the upper portion of the bobbin 513 , but the present invention is not limited thereto. The springs 518 may be installed to be spaced apart from each other by a predetermined distance. In addition, the first leaf spring 517 and the second leaf spring 518 may be implemented with the same material and/or shape, but is not limited thereto, and the first leaf spring 517 and the second leaf spring 518 . may be implemented with different materials and/or shapes. In addition, the leaf springs 517 and 518 are not limited to the above description, and may be implemented as a single leaf spring without being double installed.

The head 520 may receive the generated vibration and transmit the vibration to the outside. For example, the head 520 is connected to the leaf springs 517 and 518 and the bobbin 513, and receives sound wave vibrations generated from the leaf springs 517 and 518 and/or the bobbin 513, and direct / It can be transmitted to the body of the user who has indirectly touched it. Specifically, the lower portion 522 of the head 520 is inserted into the coupling hole formed in the plate springs 517 and 518 and the coupling hole formed in the bobbin 513, the plate springs 517 and 518 and/or the bobbin 513. ) can be combined with Here, a structure to be screwed to the head 520 may be provided inside the coupling holes. Therefore, the head 520 is connected to the leaf springs 517 and 518, and when the leaf springs 517 and 518 generate vibration in the vertical direction by acoustic pressure, the vibration can be transmitted to the body.

2.2. vibration massage

As used herein, the expression “vibration massage” refers to a massage that applies vibration to a body part, and may refer to an act of stimulating a body part through vibration. For example, the vibration massage may include a motor vibration massage that transmits vibration generated by a motor to a body part, a sonic vibration massage that delivers a vibration generated by acoustic pressure to a body part, and the like. In this specification, vibration massage should be broadly interpreted to include not only sonic vibration massage, but also a massage that gives vibration stimulation to a body part through an applicator for massaging the body part. Hereinafter, for convenience of explanation, vibration massage will be described with a focus on sonic vibration massage. However, the present invention is not limited thereto, and the following descriptions are applicable to vibration massage other than the sonic vibration massage.

2.2.1. Definition and Examples of Vibration Massage

In the present specification, sound wave vibration is a type of vibration and may mean vibration generated based on the generation of sound waves. For example, the sound wave vibration may be generated due to vibration of air generated when a sound source is input to a device for outputting sound wave vibration.

In addition, sonic vibration massage means delivering sonic vibration to the user's body in order to obtain a massage effect. effect can be obtained, and it can induce a variety of effects during massage compared to other vibration massagers. For example, since the sonic vibration massage has a small repulsive force from the skin during the massage, it is possible to provide a good massage feeling to the user and reduce body fatigue that may be caused by vibration stimulation compared to other vibration massages. In addition, according to the sonic vibration massage, when sonic vibrations perpendicular to the body part are applied to the skin, penetration of the sonic vibrations applied to the body parts into the muscles may be further improved.

For example, the property of the sound wave vibration may include at least one of a frequency, an amplitude, and a waveform of the sound wave vibration. Here, the waveform is related to the degree to which the sound wave vibration is changed during the reference time unit, and may mean, for example, a change pattern of at least one of a frequency or an amplitude. As an example, the waveform may include a sinusoidal waveform, a triangular waveform, and the like.

The properties of the sonic vibration may be related to the intensity and massaging feeling of the sonic vibration massage.

For example, when the sound wave vibration of a low frequency is output from the sound wave vibration module 500, the intensity of the output sound wave vibration may be strong. That is, it is possible to provide a high-intensity sonic vibration massage to the user by using the sonic vibration of a low frequency.

For another example, when high frequency sound wave vibration is output from the sound wave vibration module 500 , the intensity of the output sound wave vibration may be weak. That is, it is possible to provide a softer sound wave vibration massage with a lower intensity to the user by using the high frequency sound wave vibration.

For example, when high-amplitude sound wave vibration is output from the sound wave vibration module 500, the intensity of the output sound wave vibration may be strong. That is, it is possible to provide a high-intensity sonic vibration massage to the user by using the high-amplitude sound wave vibration.

For another example, when sound wave vibration of low amplitude is output from the sound wave vibration module 500 , the intensity of the output sound wave vibration may be weak. That is, it is possible to provide a softer sound wave vibration massage with a lower intensity to the user by using the sound wave vibration of low amplitude.

Also, for example, when the sound wave vibration of a gently changing waveform is output from the sound wave vibration module 500, the massage feeling of the sound wave vibration output may be soft. That is, it is possible to provide a sound wave vibration massage with a softer massage feeling to the user by using the sound wave vibration of a gently changing waveform.

For another example, when a rapidly changing sound wave vibration is output from the sound wave vibration module 500, the massage feeling of the sound wave vibration output may be strong. That is, it is possible to provide a sound wave vibration massage with a stronger massage feeling to the user by using the sound wave vibration of a rapidly changing waveform.

Of course, the property of sound wave vibration is not limited to the above description, and other properties such as the volume of the input sound source may be used.

Also, in one embodiment, the sonic vibration massage may be performed in synchronization with the motion massage. This will be described in more detail in Table of Contents 3.3.

As another example, the intensity of the heat massage may be adjusted by heating or cooling the heat transfer member to a plurality of levels of temperature, and the heating and cooling rates of the heat transfer member may be adjusted in a plurality of steps to adjust the speed of the heat massage. have.

2.4 Multi-modal massage

In this specification, the multi-modal massage may mean simultaneously performing one or more massages using a plurality of applications.

It may mean that the massage device simultaneously performs a plurality of massages. In one embodiment, the massage device is a multi-modal massage, and may simultaneously perform one massage using a plurality of applicators. For example, the massage device may be a multi-modal massage, and may perform sonic vibration massage having different vibration frequencies or amplitudes using two sound wave vibration modules.

In another embodiment, the massage device may simultaneously perform two or more massages among a motion massage, a vibration massage, an air massage, and a heat massage as a multi-modal massage. For example, in the massage device, a thermal massage module may be disposed at one end of the acoustic vibration module, and the acoustic vibration massage may be provided using the acoustic vibration module and thermal massage may be provided using the thermal massage module.

As another example, the massage device may provide a motion massage using a massage ball and simultaneously perform a sonic vibration massage using a sonic vibration module.

Here, the provided massage may include the aforementioned motion massage, sonic vibration massage, air massage, and thermal massage, but for convenience of description, the description will be focused on providing the motion massage.

3.1.2.1. Position recognition of the applicator

In one embodiment, the massage device may determine the position of the applicator (S1000). Specifically, in one embodiment, the massage device may include a position sensing unit (not shown). The position sensing unit may detect the position of the massage unit itself or a component thereof. For example, the position detection unit may determine the position of the massage unit by using a position detection sensor provided in a preset area of the massage device. Here, the position detection sensor may include at least one sensor for detecting at least one of a vertical position and a horizontal position of the massage unit.

The position sensing unit may include, for example, an encoder, a magnetic sensor, an optical sensor, a pressure sensor, and the like. For example, the position sensing unit may include an encoder, and may calculate the position of the massage unit by using a rotation value of a motor included in the driving unit. For another example, the position detecting unit may include an optical sensor, and by recognizing a connection unit that moves as the acoustic vibration module and/or the massage ball comes into contact with the body by the driving unit, the position of the massage unit may be calculated.

Such a position sensor may detect the position of the massage unit, and may calculate the position of the applicator based on the detected position of the massage unit.

For another example, the control unit may determine the location of the applicator from a memory (not shown) in which the location information of the applicator installed at a preset location is stored. Here, the applicator may be in a fixed form by being fixedly installed on the massage device.

3.1.2.2. Provides motion massage based on the position of the applicator

In one embodiment, the massage device may provide a massage corresponding to the position of the applicator (S1100).

In an embodiment, the controller may provide a massage through the massage unit for each position of the massage unit based on the confirmed position of the massage unit. For example, the control unit provides a first massage through the massage unit at a first position of the massage unit, and applies a second massage different from the first massage to the massage unit at a second position of the massage unit different from the first position. can be provided through Here, the massage provided for each position of the applicator may be different in the type of massage, the strength of the massage, the properties of the massage, a combination thereof, and the like. For example, the massage device may provide sonic vibration massage, motion massage or other massage depending on the position of the applicator, and the intensity or characteristics of each massage provided may be different.

In another embodiment, the controller may estimate the user's body shape using the location of the application, and provide a massage based on the estimated body shape.

Specifically, the controller may detect a body part of the user through the position sensor, and estimate the user's body type based on the sensed position of the body part. For example, the controller may detect the user's shoulder through the position sensor, and estimate the user's body length using the sensed position of the shoulder. As another example, the controller may detect the left and right ends of the user through the position detecting unit, and estimate the user's body width using the detected positions of the ends.

More specifically, the massage device may detect the position of the user's shoulder. The control unit may detect the user's shoulder through the position sensing unit in order to estimate the user's body type. For example, the controller may move the massage unit up and down along the backrest, and detect the user's shoulder based on a change in load according to the up and down position of the applicator. Here, when the applicator moves upwards beyond the user's shoulder, the load sensed by the position sensor is reduced, so the upper and lower positions of the shoulder position can be known. The magnitude of the load is also related to the front and rear positions of the applicator, so when the shoulder position is sensed, the front and rear positions of the applicator detected from the position sensor may also be considered.

Also, the massage device may estimate the length of the user's body using the sensed position of the shoulder. The controller may estimate the user's body length based on a length between the sensed shoulder position and a preset position. For example, the controller may estimate the length between the sensed position of the shoulder and the position near the hip as the length of the user's upper body. Here, the position near the hip may be detected by a separate position sensor, or the body length of the user may be estimated in another form, such as estimating the user's body length using the position near the foot instead of the position near the hip.

Also, the massage device may determine a body part corresponding to the position of the massage means based on the estimated body length. The controller may divide the estimated body length into a plurality of sections each having a predetermined ratio, and determine a body part corresponding to each section. That is, the controller may determine the body part based on the vertical position. Here, the preset ratio may be set based on a standard ratio for each body part of a person. For example, the massage device may divide the body length into three sections according to a standard ratio for each body part, and may correspond each section to a shoulder, a waist, and a hip region.

In addition, the controller may obtain the user's body information (eg, the user's weight, height, BMI information, etc.) from the manipulation unit (not shown), and estimate the user's body characteristics based on the obtained body information.

Also, the controller may estimate the user's body type through a sensor provided in the massage device. For example, the controller may detect a pressure applied by the user using a pressure sensor, and estimate the user's body type using the sensed pressure. For example, the controller may estimate the user's muscle mass, fat mass, etc. based on the pressure sensed by the pressure sensor. This is because the pressure detected by the pressure sensor is different depending on the amount of bone, fat, or muscle.

Also, the massage apparatus may determine a body part to which a massage is provided based on the estimated user's body type. For example, the control unit may determine the position of the massage means through the position sensing unit, and determine which body part the applicator is located on the basis of the estimated user's body type. Accordingly, the massage device may more accurately determine a body part by considering body characteristics for each user.

In addition, the massage device determines the estimated user's body type and/or body part to which massage is provided, and selects a massage type, massage intensity, massage speed, etc. suitable for the user's body shape and/or body part to which the massage is provided, An optimal massage can be provided to the user.

It may include at least one of the modules, but is not limited thereto. Also, as an example, the communication unit 720 may receive a sound source signal from an external device, and the received sound source signal may be stored in the storage unit 710 .

In an embodiment, the input unit 730 may receive data for controlling the massage device from the user. For example, the input unit 730 may include a remote control for controlling the massage device. Also, the input unit 730 may receive information for controlling the sound wave vibration module 500 . Illustratively, the information for controlling the sound wave vibration module 500 includes information for receiving a selection of a sound source signal to be applied to the sound wave vibration module from among a plurality of sound source signals, information about controlling the intensity of the sound source signal, or the sound source signal It may include information about frequency control. Also, the information received from the input unit 730 may be other various types of information. For example, the information received from the input unit 730 may include information about a massage mode included in the above-described massage program.

In one embodiment, the output unit may refer to a device for displaying information about the massage device to the user. As an example, the output unit may include a media output unit and a sound source output unit.

For example, the media output unit is a component that outputs media data to a user, and may refer to a module such as a display such as an LCD. Also, the media output unit may display frequency information of a sound source signal for controlling the sound wave vibration module 500 or intensity information of the sound source signal.

As another example, the sound source output unit is configured to output a sound source signal having a specific frequency to the user. For example, the sound source output unit may include a speaker.

Also, in one embodiment, the controller 600 may perform a motion massage operation based on the sound source signal. For example, the control unit 600 may generate a control signal based on the sound source signal and apply the control signal to the driving unit 100 or the motor. Accordingly, the motion massage operation and the sonic vibration massage operation may be synchronized by the sound source signal.

Hereinafter, the control method of the control unit 600 will be described in detail.

15 is an operation flowchart illustrating a control method of a controller according to an exemplary embodiment.

Referring to FIG. 15 , the control method of the controller according to an embodiment includes obtaining a sound source signal (S2110), generating a control signal based on the sound source signal (S2130), and applying the control signal to a sound wave vibration module It may include a step (S2150) of doing.

In step S2110 , the control unit 600 may obtain a sound source signal from the outside or the inside of the sound wave vibration module 500 . Specifically, the control unit 600 obtains a sound source signal from an external device (eg, mobile, sound server, etc.) through the communication unit 720 or a sound source stored in advance in the storage unit 710 of the sound wave vibration module 500 . signal can be loaded.

More specifically, the control unit 600 may obtain a sound source file (eg, wav file, mp3 file, etc.) through the communication unit 720 through an external device, and store the obtained sound source file in the storage unit 710 . . The controller 600 may use the obtained sound source file as a sound source signal or convert the obtained sound source file into a sound source signal. In addition, the control unit 600 obtains a file including a sound source (eg, an image file including a sound source) through the communication unit 720, and stores the file including the obtained sound source in the storage unit 710. have. The controller 710 may extract a sound source signal from a file including a sound source.

Also, in step S2130 , the controller 600 may generate a control signal based on the adjusted sound source signal after adjusting the frequency and/or intensity of the obtained sound source signal. Of course, according to an embodiment, the controller 600 may generate a control signal based on the sound source signal without adjusting the frequency and/or intensity of the sound source signal.

In addition, the control unit 600 may process the sound source signal to be suitable for the massage operation. For example, the controller 600 may process the sound source signal by adjusting the sound source reproduction time, frequency, intensity, etc. of the sound source signal to be suitable for the motion massage operation. The controller 600 may generate a control signal based on the processed sound source signal.

Also, in step S2150 , the controller 600 may apply a control signal to the sound wave vibration module 500 so that a control signal having a specific frequency and intensity is output from the sound wave vibration module 500 .

For example, the control signal may be an electrical signal. In this case, the controller 600 may apply the control signal to the coil 514 . In this case, the control signal may be an AC signal or a flow signal. In addition, the controller 600 may adjust the intensity of the control signal to adjust the intensity of vibration generated by the sound wave vibration module 500 . That is, the controller 600 may apply the control signal whose intensity is adjusted to the sound wave vibration module 500 .

The sound wave vibration module 500 may generate sound wave vibration according to a control signal. At this time, the sound wave vibration generated by the sound wave vibration module 500 may correspond to the characteristics of the sound source signal that is the basis of the control signal. For example, the sound wave vibration module 500 may output sound wave vibration according to the frequency and intensity of the sound source signal. That is, the frequency change and intensity change according to time of the sound source signal may be reflected in the frequency and intensity of the sound wave vibration.

Meanwhile, the controller 600 may control the output unit to output the frequency type and intensity level of the sound source signal input by the user through a display or the like. Also, the controller 600 may control a sound source signal having a specific frequency and intensity input by a user to be output to a speaker or the like through the output unit. In addition, the control unit 600 may control the sound source signal input by the user to be output in the form of vibration through the sound wave vibration generating unit 1100 . In other words, the controller 600 may control one sound source signal to be simultaneously output from the sound wave vibration module 500 and the output unit 740 . Also, in another embodiment, different sound source signals may be simultaneously output from the sound wave vibration module 500 and the output unit 7400 .

3.2.2. sound signal

As described above, the sound source signal may be composed of an audible frequency. This is, when a control signal based on the sound source signal of the audible frequency band is applied to the sonic vibration module 500, the sonic vibration module can generate sonic vibration of the audible frequency band, and the sonic vibration of the audible frequency band is massaged for the user. This may be because it can increase the effectiveness.

In one embodiment, the frequency and/or intensity of the sound source signal may change over time. Specifically, the frequency and/or intensity of the sound source signal may be changed, such as increasing and then decreasing with the passage of time, which may appear as a waveform characteristic of the sound source signal. In addition, the sound wave vibration module 500 may output sound wave vibration according to the waveform characteristics of the sound source signal. Accordingly, it can be said that the waveform characteristics of the sound source signal reflect the characteristics of the sound wave vibration output from the sound wave vibration module 500 . And, according to the characteristics of the sound wave vibration, the sound wave vibration module 500 may provide various sound wave vibration massages to the user.

3.2.2. Sound Waveform Characteristics

16 is a graph illustrating examples of sound source waveforms according to an embodiment. Referring to FIG. 16 , in this specification, a waveform of a sound source signal may be expressed as a sound source waveform. In addition, the sound source waveform may be expressed as a driving waveform and a sound wave vibration waveform. Also, in an embodiment, since the sound source waveform may be generated based on two or more waveforms or may be a waveform in which two or more waveforms are synthesized, the sound source waveform may also be expressed as a synthesized waveform.

In an embodiment, the sound source signal may have various types of waveforms. As the sound source signal has various types of waveforms, it may be possible to provide various patterns of sound wave vibration massage.

Specifically, in (a) to (e), the x-axis may represent time, and the y-axis may represent amplitude. First, (a) shows a sound source waveform having a sine wave. As in (a), in the sound source waveform, the change in amplitude with time appears in the form of a sine wave, and the waveform may be repeated according to a predetermined period. In (a), the number of cycles of the waveform repeated per second may be the frequency. When the control signal corresponding to the sound source signal having the sound source waveform of (a) is applied to the sound wave vibration module 500, the number of vibrations per second of the sound wave vibration module 500 by the frequency of the waveform of (a) (for example, The number of vibrations of the head 520) is determined, and the vibration range (eg, the vibration range of the head 520) of the sound wave vibration module 500 may be determined by the amplitude of the frequency of the waveform of (a).

Also, in one embodiment, the sound source waveform may have a shape other than a sine wave. For example, (b) shows a sound source waveform having a square wave, (c) shows a sound source waveform having a triangular wave, and (d) shows a sound source waveform having a sawtooth wave. Of course, the sound source waveform may be composed of a waveform other than the waveforms shown in (a) to (d).

In addition, although the sound source waveform shown in (a) to (d) has a constant frequency and amplitude, it is not limited thereto, and the frequency and/or waveform of the sound source waveform may be varied. For example, (e) may represent a sound source waveform having a sine wave. In the example of (e), the frequency of the sound source waveform is decreased and then increased again, and the amplitude of the sound source signal is decreased and then increased. This may indicate that the frequency and/or amplitude of the sound source signal may vary over time.

17 is a graph showing examples of sound source waveforms according to another embodiment.

Referring to FIG. 17 , a sound source waveform may be generated based on two or more basic waveforms. For example, the sound source waveform may be a form in which two or more basic waveforms are synthesized. For example, the sound source waveform may represent a form in which two basic waveforms are added or a form in which two basic waveforms are multiplied. Also, the present invention is not limited thereto, and the sound source waveform may be generated by synthesizing three or more basic waveforms more than two basic waveforms.

According to an embodiment, in (a) to (d) of FIG. 17 , the x-axis may represent time, and the y-axis may represent amplitude. And, (a) shows the first basic waveform, (b) shows the second basic waveform. Here, the first basic waveform and the second basic waveform may each represent a sound source waveform or may represent a waveform other than the sound source signal. In addition, the first basic waveform and the second basic waveform may represent a sine wave, and the frequency of the second basic waveform may be higher than the frequency of the first basic waveform. Of course, the first basic waveform and the second basic waveform may be waveforms other than the sine wave.

(c) is a first d in which the first basic waveform and the second basic waveform are summed. Also, (d) is a second synthesized waveform obtained by multiplying the first basic waveform and the second basic waveform.

As shown in (c) and (d), the amplitude change degree and amplitude change period of the first synthesized waveform and the second synthesized waveform may be different from those of the first and second basic waveforms. Accordingly, when the sound wave vibration module 500 is controlled using the synthesized waveform, it is possible to provide a sound wave vibration massage with various feelings to the user.

3.2.3. Sonic vibration massage according to frequency and amplitude change

18 is a graph for explaining a change in intensity of a sound wave vibration massage according to a change in frequency and amplitude of a sound source signal according to an embodiment.

Referring to FIG. 18 , the intensity of the sonic vibration massage may vary according to the frequency and/or amplitude of the sound source signal. Here, the intensity of the sonic vibration massage may be the intensity actually felt by the user, or it may represent the intensity provided to the real user.

In one embodiment, even when the amplitude of the sound source signal is the same, the intensity of the sound wave vibration massage may be changed according to a change in frequency.

In (a), the x-axis represents time, the y-axis represents frequency, in (b), the x-axis represents time, and the y-axis may represent the intensity of sound wave vibration massage. In (a), the sound wave signal may be maintained at the first frequency until time t1, and after time t1, the first frequency may be maintained as a low second frequency. At this time, as in (b), the intensity of the sonic vibration massage up to the time point t1 may be lower than the intensity after the time point t1. At this time, even when the amplitude of the sonic vibration massage in the control signal is set to be the same, the intensity of the sonic vibration massage after the time t1 may be higher than that before the time t1.

In addition, in one embodiment, when the frequency of the sound source waveform is the same, the intensity of the sound wave vibration massage may vary according to the change in amplitude.

In (c), the x-axis represents time, the y-axis represents the amplitude of the sound source signal, in (d), the x-axis represents time, and the y-axis represents the intensity of sound wave vibration massage. In (c), the sound wave signal may be maintained with a first amplitude until time t1, and may be maintained with a second amplitude lower than the first amplitude after time t1. At this time, as in (d), according to the amplitude of the sonic vibration massage, the intensity of the sonic vibration massage up to the time point t1 may be higher than the intensity after the time point t1.

3.2.4. Sonic vibration massage according to the movement of the sonic vibration module

3.2.4.1. Sonic vibration massage according to the movement cycle of the sonic vibration module

3.2.4.1.1. Synchronization Waveform and Vibration Waveform

As described above, the control unit 600 may provide a sound wave vibration massage of various feelings to the user by generating a control signal using the sound source waveform and applying the control signal to the sound wave vibration module.

To describe the sound source waveform in more detail, the sound source waveform may be generated based on the synchronization waveform and the vibration waveform. Here, the synchronization waveform affects the overall waveform shape of the sound source waveform, for example, the envelope of the sound source waveform, and may be a waveform having a low frequency among basic waveforms that are the basis of the sound source waveform. In addition, the synchronization waveform may have a predetermined pattern, and accordingly, the synchronization waveform may be expressed as a synchronization pattern or a synchronization vibration pattern.

Also, the synchronization waveform may affect the vibration pattern of the sonic vibration module.

In addition, the vibration waveform affects the detailed frequency of the sound source waveform, for example, the frequency of the vibration waveform may be included in the audible frequency band. In addition, the vibration waveform may also have a predetermined pattern, and accordingly, the vibration waveform may be expressed as a vibration pattern.

Hereinafter, the frequency of the synchronization waveform may be expressed as a synchronization frequency, and the frequency of the vibration waveform may be expressed as a vibration frequency. Also, in this specification, the synchronization waveform and the vibration waveform may also be expressed as the synchronization signal and the vibration signal.

In one embodiment, the synchronization waveform may consist of various waveforms.

19 is a graph for explaining an example of a synchronization waveform according to an embodiment.

Referring to FIG. 19 , (a) to (c) are graphs illustrating synchronization waveforms, where the x-axis may represent time and the y-axis may represent amplitude. The synchronization waveform may include a sine wave as shown in (a), a square wave as shown in (b), and a complex waveform as shown in (c). Of course, in addition to this, the synchronization waveform may be composed of various waveforms such as a triangular waveform and a sawtooth waveform.

For example, in (b), the square waveform is a form in which two waveforms having different amplitudes are alternately represented, and there may be a predetermined idle time between each square waveform, and during the idle time, the sound wave vibration module generates sound wave vibrations. can stop Of course, in the example of (b), two detailed synchronization waveforms may continuously alternately appear without an idle time. Also, in (c), the composite waveform may be represented by alternating elliptic waveforms and linear waveforms. Of course, in the example of (c), an elliptical waveform may be repeated without a straight waveform in the complex waveform, or elliptical waveforms with a changed shape may be repeatedly displayed.

Also, in one embodiment, the synchronization waveform may be associated with movement of the sonic vibration module.

The position of the sonic vibration module may be fixed to provide the sonic vibration massage, but the sonic vibration massage may be provided while the sonic vibration module moves. At this time, according to an embodiment, the sound wave vibration massage may be provided while the sound wave vibration module moves according to predetermined movement patterns. The synchronization waveform may be synchronized with the predetermined movement patterns. For example, when the sonic vibration module moves by a first position in the z-axis to press the user with a first intensity, the sonic vibration module may provide a high-intensity sonic vibration massage, and the sonic vibration module moves in the z-axis When the user presses the user with a second intensity lower than the first intensity by moving as much as a second position closer to the massage unit than the first position, the sonic vibration module may provide sonic vibration massage with a low intensity. In this way, the position of the sound wave vibration module and the intensity of the sound wave vibration massage may have a similar tendency or be synchronized, and for this purpose, the movement pattern and the synchronization waveform of the sound wave vibration module may have a similar tendency or be synchronized. This is because the synchronization waveform affects the overall waveform shape of the sound source waveform, that is, the overall vibration pattern of the sound wave vibration massage.

Also, the location of the sonic vibration module may be associated with other massages, such as motion massage. For example, as described above in FIGS. 3 and 4 , when the massage ball 400 and the sonic vibration module 500 for providing a motion massage to one connection part 200 are connected at the same time, the sonic vibration module 500 is It may move according to the movement of the massage ball 400 , that is, the pattern of motion massage. Accordingly, the synchronization waveform may have a similar tendency or be synchronized with a pattern of other massages such as motion massage.

20 is a graph for explaining an example of a vibration waveform according to an embodiment.

Referring to FIG. 20 , (a) to (d) are graphs illustrating vibration waveforms, wherein the x-axis may represent time and the y-axis may represent amplitude. The vibration waveform may include a sine wave as shown in (a), a square wave as shown in (b), a sawtooth wave as shown in (c), and a triangular waveform as shown in (d). Of course, in addition to this, the synchronization waveform may be composed of various waveforms such as a complex waveform.

The vibration waveform affects the number of detailed amplitudes of the sound source waveform, and the vibration frequency of the vibration waveform may be higher than the synchronization frequency of the synchronization waveform. Accordingly, according to the vibration frequency of the vibration waveform, the number of times the sound wave vibration module is repeated while the synchronization waveform proceeds for one period may be determined.

Also, in one embodiment, the vibration frequency may be an audible frequency band. For example, the vibration frequency may be configured from 80 to 300 hz.

In addition, the amplitude and frequency of the vibration waveform may be variously configured. For example, one may include detailed vibration waveforms with different amplitudes and/or frequencies.

21 is a graph illustrating an example of a sound source waveform according to an embodiment.

Referring to FIG. 21 , in (a) to (c), the x-axis may represent time, and the y-axis may represent amplitude. Specifically, in (a) to (c), the vibration waveform may be the sine wave of FIG. 20 (a), and the synchronization waveform is the square waveform of FIG. It may be a sine wave in (b) and a complex waveform in (c) of FIG. 19 in (c).

As shown in (a) to (c) of FIG. 21 , the overall waveform of the sound source waveform may be greatly affected by the synchronization waveform. For example, the envelope of the sound source waveform of (a) may be a square waveform that is a synchronization waveform, and the envelope of the sound source waveform of (b) may have a shape in which a sine wave, which is a synchronization waveform, appears symmetrically with respect to the y-axis. And, the envelope of the sound source waveform of (c) may be of a form in which a composite waveform of an elliptical waveform and a linear waveform, which is a synchronization waveform, appears symmetrically with respect to the y-axis. In addition, detailed waveforms may be filled in the envelope of the sound source waveform, and the frequency of the detailed waveform may be determined based on the frequency of the vibration waveform. Since detailed waveforms exist within the envelope of the sound source waveform, sound wave vibration may be generated in the sound wave vibration module based on the sound source waveform, and a more three-dimensional and various sound wave vibration massage may be provided to the user.

3.2.4.1.2. The movement period and synchronization waveform of the acoustic vibration module

22 is a graph illustrating a relationship between a movement period of a sound wave vibration module and a synchronization waveform according to an embodiment.

Referring to FIG. 22 , (a) represents the movement period of the sound wave vibration module, the x-axis may represent time, and the y-axis may represent the movement length of the sound wave vibration module along the z-axis. According to (a), the sound wave vibration module can repeatedly perform a movement pattern of moving from the reference position in the z-axis direction according to the shape of a sine wave, then retreating in the -z-axis direction, and then moving back to the reference position. As described above, the synchronization waveform may be synchronized with the movement pattern of the acoustic vibration module. That is, the vibration pattern of the sound wave vibration module and the movement pattern of the sound wave vibration module may be synchronized. Specifically, the period of the synchronization waveform may be n times or 1/n times the period of the movement pattern of the acoustic vibration module (where n is a natural number). This may be to provide a comfortable massage by minimizing a sense of heterogeneity as the massage device simultaneously provides stimulation and sonic vibration massage according to the movement of the sonic vibration module. The massage device at least partially matches the start and end points of the movement pattern of the sonic vibration module and the start and end points of the vibration pattern of the sonic vibration massage, thereby providing a comfortable massage with the minimal sense of heterogeneity to the user. Of course, even if the start and end points of the movement pattern of the sound wave vibration module and the start and end points of the synchronization waveform do not necessarily coincide, the synchronization waveform within a predetermined time based on the start and end points of the movement pattern of the sound wave vibration module When the start time and the end time of the sonic vibration module are included, the possibility that the user will feel a sense of heterogeneity may be reduced by simultaneously providing the stimulation according to the movement of the sound wave vibration module and the sound wave vibration massage.

In one embodiment, setting the period of the synchronization waveform to n times or 1/n times the period of the movement pattern of the sound wave vibration module causes the synchronization waveform to have a large influence on the vibration pattern of the sound wave vibration massage, and the vibration frequency of the vibration waveform This is because may be more likely to vary than the synchronization frequency of the synchronization waveform according to a user input or a predetermined setting. Of course, the vibration pattern of the sonic vibration massage may be changed by the vibration waveform together with the synchronization waveform, which will be described in more detail with reference to FIG. 25 .

Specifically, (b) to (e) represent the synchronization waveform, and the x-axis of (b) to (e) may represent time, and the y-axis may represent amplitude.

(b) may represent a case in which the period of the synchronization waveform is the same as the period of the movement pattern of the sound wave vibration module. In other words, the frequency of the synchronization waveform may be the same as the frequency of the movement pattern of the sound wave vibration module. In this case, the start time of the movement pattern of the sound wave vibration module may correspond to the start time of the synchronization waveform, and the end time of the movement pattern of the sound wave vibration module may correspond to the end time of the synchronization waveform. Accordingly, the possibility that the start time and end time of the movement pattern of the sonic vibration module and the start time and the end time of the vibration pattern of the sonic vibration massage can at least partially coincide with each other may increase.

(c) may represent a case where the period of the synchronization waveform is 1/2 the period of the movement pattern of the sound wave vibration module. In other words, the frequency of the synchronization waveform may be twice the frequency of the movement pattern of the acoustic vibration module. In this case, when the sonic vibration module is moved for one cycle, the sonic vibration module may perform sonic vibration massage for two cycles. In this case, the start time of the movement pattern of the sound wave vibration module may correspond to the start time of the synchronization waveform, and the end time of the movement pattern of the sound wave vibration module may correspond to the end time of the synchronization waveform. Accordingly, the possibility that the start time and end time of the movement pattern of the sonic vibration module and the start time and the end time of the vibration pattern of the sonic vibration massage can at least partially coincide with each other may increase.

(d) may represent a case where the period of the synchronization waveform is twice the period of the movement pattern of the sound wave vibration module. In other words, the frequency of the synchronization waveform may be 1/2 the frequency of the movement pattern of the sound wave vibration module. In this case, when the sonic vibration module is moved for 2 cycles, the sonic vibration module may perform sonic vibration massage for 1 cycle. In this case, when the sonic vibration module is moved for two periods, the sonic vibration module may perform sonic vibration massage for one period. In this case, the start time of the synchronization waveform and the start time of the movement pattern of the sound wave vibration module may correspond, and the end time of the synchronization waveform and the end time of the movement pattern of the sound wave vibration module may correspond. Accordingly, the possibility that the start time and end time of the movement pattern of the sonic vibration module and the start time and the end time of the vibration pattern of the sonic vibration massage can at least partially coincide with each other may increase.

On the other hand, (e) may represent a case where the period of the synchronization waveform and the period of the movement pattern of the sound wave vibration module are not synchronized. In this case, the start time and end time of the movement pattern of the sound wave vibration module and the start time and end time of the synchronization waveform may not at least partially coincide. In addition, in this case, when the start and end points of the movement pattern of the sound wave vibration module and the start and end points of the synchronization waveform at least partially coincide, the period of the synchronization waveform and the period of the movement pattern of the sound wave vibration module are synchronized. may be later than usual.

For example, even when the movement pattern of the sound wave vibration module is repeated for a plurality of cycles, there is no point at which the start time and end time of the movement pattern of the sound wave vibration module and the start time and end time of the synchronization waveform match, or The timing may be delayed. In this case, the possibility that the start time and end time of the movement pattern of the sonic vibration module and the start time and the end time of the vibration pattern of the sonic vibration massage can at least partially coincide with each other may be reduced. Accordingly, the possibility that the user will feel a sense of heterogeneity may be increased by simultaneously providing stimulation according to the movement of the sonic vibration module and the sonic vibration massage. Accordingly, the massage device may adjust the frequency (or period) of the synchronization waveform so that the start time and end time of the movement pattern of the sound wave vibration module and the start time and end time of the vibration pattern of the sound wave vibration massage at least partially coincide.

In addition, the above examples may be applied to a case in which the synchronization pattern is various waveforms such as a square wave, a triangular wave, a sawtooth wave, and a complex wave.

3.2.4.1.3. The movement period of the sound wave vibration module and the sound source waveform

23 and 24 are graphs for explaining a period of a sound source waveform according to a vibration frequency of a vibration waveform according to an exemplary embodiment.

23 and 24, (a) shows a synchronization waveform, (b) shows a vibration waveform, (c) shows a sound source waveform and a synchronization waveform composed of a product of a synchronization waveform and a vibration waveform, (d) may represent a sound source waveform and a synchronization waveform composed of the sum of the synchronization waveform and the vibration waveform. In (c) and (d), the first sound source waveform and the second sound source waveform may be indicated by a dotted line, and the synchronization waveform may be indicated by a solid line. Also, in (a) to (d), the x-axis may represent time and the y-axis may represent amplitude.

In one embodiment, in order to provide a vibration massage without heterogeneity to the user, the movement pattern of the sound wave vibration module and the sound source waveform may be synchronized. This is because the sonic vibration module can provide sonic vibration massage based on the sound source waveform.

Even if the movement pattern of the sound wave vibration module and the synchronization waveform are synchronized, the movement pattern of the sound wave vibration module and the sound source waveform may not necessarily be synchronized. This is because, due to the synthesis of the synchronization waveform and the vibration waveform, the synchronization waveform and the sound source waveform may be synchronized, but may not be synchronized. Assuming that the synchronization waveform is synchronized with the movement pattern of the sound wave vibration module, it may be the waveform and/or the vibration frequency of the vibration waveform that affects the synchronization of the movement pattern of the sound wave vibration module and the sound source waveform. This will be described in detail below. However, for convenience of explanation, on the assumption that the waveform of the vibration waveform is a sine wave, the movement pattern of the sound wave vibration module according to the frequency change of the vibration waveform and synchronization with the sound source waveform will be described.

In an embodiment, the synchronization period of the synchronization waveform may be n times or 1/n times (where n is a natural number) of the vibration period of the vibration waveform. This is because, when the synchronization period of the synchronization waveform is n times or 1/n times the vibration period of the vibration waveform, the synchronization waveform or the movement pattern of the sound wave vibration module and the sound source waveform may be more likely to be synchronized.

Of course, in the case of sound wave vibration, since the synchronization period may be higher than the vibration period, an embodiment in which the synchronization period is 1/n times the vibration period may be a main embodiment.

Specifically, (a) of FIG. 23 may indicate a first synchronization waveform, and FIG. 24(a) may indicate a second synchronization waveform. In this case, the first synchronization waveform and the second synchronization waveform may be the same waveform, the waveforms of the first and second synchronization waveforms may be sine waves, the frequency may be 50hz, and the period may be 0.02s. In addition, FIG. 23B may represent a first vibration waveform, and FIG. 24B may represent a second vibration waveform. At this time, the waveforms of the first vibration waveform and the second vibration waveform are sine waves, but the frequency of the first vibration waveform is 100 Hz, the period is 0.01 s, while the frequency of the second vibration waveform is 107 Hz, and the period is 1/107 can be s. That is, the period of the first vibration waveform compared to the period of the first synchronization waveform may be 1/n times, but the period of the second vibration waveform compared to the second synchronization waveform may not be 1/n times.

23( c ) may show a first sound source waveform and a first synchronization waveform obtained by multiplying the first synchronization waveform and the first vibration waveform. Also, (d) of FIG. 23 may represent a second sound source waveform and a first synchronization waveform in which the first synchronization waveform and the first vibration waveform are added. At this time, as the period of the first synchronization waveform and the period of the first vibration waveform have a 1/n-fold relationship, it may be different depending on the waveform, but in the embodiment of FIG. 23 , the period of the first sound source waveform and the second sound source The period of the waveform may be the least common multiple of the period of the first synchronization waveform and the period of the first oscillation waveform, that is, 0.02s equal to the period of the first synchronization waveform. As the period of the first sound source waveform and the second sound source waveform is the same as the period of the first synchronization waveform, when the massage device provides a sonic vibration massage based on the first sound source waveform or the second sound source waveform, the massage device uses sound waves By at least partially matching the start and end points of the movement pattern of the vibration module and the start and end points of the vibration pattern of the sonic vibration massage within a predetermined period (or predetermined time), a comfortable massage with minimal heterogeneity can provide users

On the other hand, (c) of FIG. 24 may represent a third sound source waveform and a second synchronization waveform obtained by multiplying the second synchronization waveform and the second vibration waveform. In addition, (d) of FIG. 23 may represent a fourth sound source waveform and a second synchronization waveform in which the second synchronization waveform and the second vibration waveform are added. At this time, since the period of the second synchronization waveform and the period of the second vibration waveform do not have a 1/n-fold or n-fold relationship, the period of the third sound source waveform and the period of the fourth sound source waveform are the period of the first synchronization waveform may not match

In the massage device, the start time and end time of the movement pattern of the sound wave vibration module and the start time and end time of the vibration pattern of the sound wave vibration massage do not coincide continuously within a predetermined period (or a predetermined time), so that the sound wave vibration The movement of the module and the sonic vibration massage may not be synchronized, and accordingly, the possibility that the user feels a sense of heterogeneity may be increased by simultaneously providing stimulation according to the movement of the sonic vibration module and the sonic vibration massage. Therefore, the massage device may adjust the frequency (or period) of the synchronization waveform and the frequency (or period) of the vibration waveform so that the period of the synchronization waveform and the period of the vibration waveform are 1/n times or n times.

Further, in one embodiment, even when the synchronization period of the synchronization waveform and the vibration period of the vibration waveform do not have a relationship of n times or 1/n times, the difference between the synchronization period and the least common multiple of the synchronization period and the vibration period is a predetermined value. value can be within The time point at which the synchronization period and the oscillation period become the least common multiple may be the time point at which the end point of the synchronization waveform coincides with the end time of the sound source waveform, and if the difference between the synchronization period and the least common multiple of the oscillation period is not large with the synchronization period, This is because there is a high possibility that the user will not feel a sense of heterogeneity.

25 is a graph for explaining a period of a sound source waveform according to a vibration frequency of a vibration waveform according to another exemplary embodiment.

Referring to FIG. 25 , (a) may represent a first synchronization waveform, the waveform of the first synchronization waveform may be a sine wave, a frequency may be 50hz, and a period may be 0.02s. In addition, (b) represents the first vibration waveform, the waveform of the first vibration waveform is a sine wave, but the frequency of the first vibration waveform may be 75hz, and the period may be 1/75s. In addition, (c) shows a first sound source waveform and a first synchronization waveform obtained by multiplying a first synchronization waveform and a first vibration waveform, (d) illustrates a second sound source waveform obtained by adding a first synchronization waveform and a first vibration waveform, and It may represent a first synchronization waveform. In (c) and (d), the first sound source waveform and the second sound source waveform may be indicated by a dotted line, and the first synchronization waveform may be indicated by a solid line.

In the embodiment of FIG. 25 , the period of the first synchronization waveform and the period of the first vibration waveform may not have a relationship of n times or 1/n times (where n is a natural number). Accordingly, the period of the first and second sound source waveforms may not coincide with the period of the first synchronization frequency. However, the period of the first and second sound source waveforms may be 1/25s, which is the least common multiple of the period of the first synchronization waveform and the period of the first vibration waveform, which is twice the period of the first synchronization waveform, 1/50s. can be That is, when the first synchronization frequency is repeated twice, the end time of the first synchronization waveform and the end time of the first and second sound source waveforms may coincide. As such, when the synchronization frequency is repeated within a predetermined number of times (two times in the embodiment of Fig. 25), if the synchronization waveform and the sound source waveform coincide, that is, the period of the synchronization waveform and the least common multiple of the period of the vibration waveform and the synchronization waveform If the difference value with the period is within a predetermined value (the period of the synchronization waveform in the embodiment of FIG. 25 ), the user may not feel a sense of heterogeneity in the sonic vibration massage. Therefore, the massage device adjusts the frequency (or period) of the synchronization waveform and the frequency (or period) of the vibration waveform so that the difference between the period of the synchronization waveform and the minimum common multiple of the period of the vibration waveform and the synchronization period is within a predetermined value. can be adjusted

When the intensity of stimulating the user by the movement of the sound wave vibration module is high, the user can feel a natural massage when the strong intensity sound wave vibration massage is provided. On the other hand, if the high intensity sonic vibration massage is provided when the intensity of stimulating the user by the movement of the sonic vibration module is low, the user may feel a relatively large amount of heterogeneity. Accordingly, the massage device provides a strong sonic vibration massage when the intensity of stimulating the user by the movement of the sonic vibration module is high, and when the intensity of stimulating the user by the movement of the sonic vibration module is low, a sound wave of weak intensity The sonic vibration module may be controlled to provide vibration massage.

26 is a graph for explaining a relationship between a synchronization waveform and a sound source waveform according to an exemplary embodiment.

Referring to FIG. 26, (a) shows a synchronization waveform, (b) shows a time point when the maximum value appears in the first sound source waveform, and (c) shows a time point when the maximum value appears in the second sound source waveform can represent In (a) to (c), the x-axis may represent time, and the y-axis may represent amplitude. Here, the time point at which the maximum value appears in the sound source waveform may correspond to the time point at which the sound wave vibration massage of the strongest intensity is provided.

In an embodiment, the time point at which the maximum value appears in the sound source waveform may vary according to the vibration frequency of the vibration waveform, that is, the period of the vibration waveform.

For example, when providing a sonic vibration massage by the first sound source waveform, as shown in (b), the sonic vibration massage of the strongest intensity can be provided at the time t1 when the intensity of stimulating the user by the movement of the sonic vibration module is the highest. have. On the other hand, when sonic vibration massage is provided by the second sound source waveform, as shown in (c), the strongest sonic vibration massage can be provided at the time t2 when the intensity of stimulating the user by the movement of the sonic vibration module is the lowest. have. In this case, while the sonic vibration module weakly presses the user, the intensity of the sonic vibration massage is the highest, so that the user can feel a sense of heterogeneity by simultaneously providing stimulation according to the movement of the sonic vibration module and the sonic vibration massage.

In order to reduce such a sense of heterogeneity, the massage device sets the frequency (or period) of the synchronization waveform and the frequency (or period) of the vibration waveform so that the sonic vibration massage of the strongest intensity is provided at the point in time when the intensity that stimulates the user by the movement of the sound wave vibration module is highest. The frequency (or period) can be adjusted.

In addition, in one embodiment, if the intensity of stimulating the user by the movement of the sound wave vibration module is not provided at the point in time when the intensity of stimulating the user is lowest, that is, the intensity of stimulating the user by the movement of the sound wave vibration module is not provided. If the highest intensity sonic vibration massage is provided at a point other than the lowest point, the user may feel less heterogeneity. Accordingly, the massage device sets the frequency (or period) of the synchronization waveform and the frequency (or period) of the vibration waveform so that the sound wave vibration massage of the strongest intensity is not provided at the point in time when the intensity of stimulating the user by the movement of the sound wave vibration module is lowest. , cycle) can be adjusted.

3.2.4.1.4. The movement speed of the sonic vibration module and the sonic vibration massage

27 is a graph for explaining a relationship between a moving speed of a sound wave vibration module and a sound source signal according to an embodiment.

Referring to Figure 27, (a) shows the moving speed of the sound wave vibration module, (b) shows the movement trajectory of the sound wave vibration module, (c) shows the synchronization waveform of the sound source signal, (d) the sound source signal can show the vibration waveform of In (a), the x-axis represents time, the y-axis represents velocity, in (b), the x-axis represents time, and the y-axis represents the position of the acoustic vibration module on the z-axis, in (c) and (d). , the x-axis may represent time, and the y-axis may represent the amplitude of the sound wave vibration module.

In the example of FIG. 27 , as shown in (a), the moving speed of the acoustic vibration module may be doubled from the time point t1. That is, as in (b), when the moving speed of the sound wave vibration module is v2, the sound wave vibration module can reciprocate once more in the z-axis than when the moving speed of the sound wave vibration module is v1. Accordingly, for synchronization with the movement trajectory of the sound wave vibration module, the frequency of the synchronization waveform of the sound source signal may be doubled from the time point t1. That is, the period of the synchronization waveform of the sound source signal may be 1/2. However, the frequency of the vibration waveform of the sound source signal can be maintained. This is because, even if the moving speed of the sound wave vibration module is changed, it may be to reduce the user's sense of heterogeneity by providing the sound wave vibration massage with the same vibration frequency. Of course, the present invention is not limited thereto, and according to embodiments, at least one of the frequency of the synchronization waveform and or the frequency of the vibration waveform may be changed as the moving speed of the sound wave vibration module is changed. In addition, according to an embodiment, as the moving speed of the sound wave vibration module is changed, at least one of the amplitude of the synchronization waveform and/or the amplitude of the vibration waveform may be changed.

3.2.4.1.5. Stimulation intensity and sonic vibration massage of the sonic vibration module

28 is a graph for explaining the relationship between the stimulation intensity of the sound wave vibration module and the sound wave vibration massage according to an embodiment.

Referring to FIG. 28 , (a) may indicate the stimulation intensity of the acoustic vibration module, (b) may indicate the amplitude of the acoustic vibration massage, and (c) may indicate the frequency of the acoustic vibration massage. In (a), the x-axis represents time, the y-axis represents the stimulus intensity, in (b), the x-axis represents time, the y-axis represents the amplitude of sonic vibration massage, and in (c), the x-axis represents time, The y-axis may represent the frequency of the sonic vibration massage.

In one embodiment, the massage device may provide a motion massage to the user through the movement of the sound wave vibration module. At this time, the degree of stimulation provided to the user may vary according to the moving position of the sound wave vibration module. For example, as in (a), the sonic vibration module may provide motion massage with high intensity from time t1 through movement. At this time, the massage device may adjust the intensity of the sonic vibration massage in response to the intensity of the motion massage by the sonic vibration module. Accordingly, by synchronizing the intensity of the motion massage and the intensity of the sonic vibration massage to the user, it is possible to reduce the user's sense of heterogeneity and increase the satisfaction of the massage.

For example, as in (b), the massage device may increase the intensity of the sound wave vibration massage while increasing the amplitude of the sound wave vibration from the time point t1. In addition, as in (c), the massage device may increase the intensity of the sound wave vibration massage while decreasing the frequency of the sound wave vibration from the time point t1.

In addition, the stimulation intensity of the acoustic vibration module of (a) may be replaced with the stimulation strength of other applications other than the acoustic vibration module. For example, when the massage device simultaneously provides the motion massage and the sonic vibration massage, the massage device may adjust the intensity of the sonic vibration massage in response to the intensity of the motion massage by the motion massage member. As another example, when the massage device provides air massage or thermal massage and sonic vibration massage at the same time, the massage device responds to the intensity of the air massage by the air massage member or the thermal massage by the heat massage member, and the intensity of the sonic vibration massage can be adjusted

Of course, the present invention is not limited thereto, and according to embodiments, the massage device may set the intensity of the sonic vibration massage regardless of the intensity of the motion massage, the intensity of the air massage or the intensity of the heat massage, the intensity of the motion massage, the intensity of the air massage You can also adjust the intensity of the sonic vibration massage as opposed to the intensity or the intensity of the heat massage.

3.3. Multi-modal massage

3.3.1. Perform vibration massage according to different massage movements

In an embodiment, the massage device may perform a vibration massage in response to an operation of a massage other than the vibration massage. Specifically, the massage device may provide not only one type of massage, but also a plurality of types of massage at the same time. Here, providing various types of massage at the same time may be defined as a multi-modal massage.

At this time, when the vibration massage and other massages are performed independently, the user may feel a sense of heterogeneity according to the provision of a plurality of types of massage. In order for the user to more comfortably receive the massage, the massage device may provide the multi-modal massage by synchronizing the vibration massage with other massages. It will be described in more detail below.

And, for the convenience of explanation, the multi-modal massage is mainly described below with a focus on sonic vibration massage, but it is not limited thereto, and it can be applied to the technical matters described below for vibration massage other than sonic vibration massage. Of course. FIGS. 29 and 30 are operational flowcharts for a method of controlling a massage device for performing multi-modal massage according to an embodiment.

Referring to Figure 29, in one embodiment, the control method of the massage device using a first applicator to perform a first massage operation (S3100) and a second corresponding to the first massage operation using a second applicator It may include performing a massage operation (S3200).

Specifically, in step S3100, the first applicator may include various massage members, such as the aforementioned motion massage member, air massage member, and heat massage member. In addition, the first massage refers to a massage corresponding to the first applicator. For example, when the first applicator is a motion massage member, the first massage may be a motion massage.

In addition, in step S3200, the second applicator may mean a vibration massage member. For convenience of description, a sound wave vibration massage member among the vibration massage members will be specifically described as the second applicator. The massage device may perform sonic vibration massage by using a sonic vibration massage member. In this case, the massage device may provide the second massage, that is, the sonic vibration massage, in synchronization with the operation of the first massage.

More specifically, referring to FIG. 30 , in step S3200 , the control method of the massage device includes checking characteristics of the first massage operation ( S3210 ), and performing a second massage operation in response to the characteristics of the first massage operation ( S3210 ). It may include adjusting the characteristic (S3220) and performing the second massage operation according to the adjusted characteristic of the second massage operation (S3230).

Here, the characteristics of the massage operation may include various parameters that can represent the massage operation, such as the type of massage, the speed of the massage, the strength of the massage, the movement pattern of the applicator, and the movement speed of the applicator.

In step S3210, the massage device may check the characteristics of the first massage operation. For example, when the first massage is a motion massage, the massage device may determine the type of motion massage (eg, tapping massage, kneading massage, etc.), the speed of the motion massage, the intensity of the motion massage, the movement pattern of the motion massage member, or You can check the movement speed, etc.

In an embodiment, when the first massage is performed according to a predetermined program, the massage apparatus may confirm the characteristics of the first massage operation from the predetermined program. In another embodiment, the massage device may analyze the operating characteristics of the first applicator in real time using various sensors included in the massage device.

In addition, in step S3220, the massage device may adjust the characteristics of the second massage operation in order to synchronize the second massage operation with the first massage operation. For example, when the second massage is a sonic vibration massage and the first massage is a motion massage, the massage device adjusts the frequency, amplitude, and movement pattern or movement speed of the sonic vibration massager according to the characteristics of the motion massage operation. Can be adjusted. For example, the massage device may select a sound source signal corresponding to the first massage operation characteristic from among the plurality of sound source signals, and adjust the amplitude of the sound source signal to adjust the characteristics of the sound wave vibration massage. As another example, the massage device may adjust the characteristics of the sound wave vibration massage by adjusting the frequency and amplitude of the sound source signal in real time. As another example, the massage device may adjust the characteristics of the sound wave vibration massage by changing the direction of the current applied to the sound wave vibration module, adjusting the intensity of the current, changing the direction of the voltage, and adjusting the magnitude of the voltage.

In addition, in one embodiment, the massage device may adjust the characteristics of the second massage operation according to the second massage operation program stored in the predetermined program, and the first massage operation according to the first massage operation program stored in the predetermined program It is also possible to adjust the operating characteristics of In addition, the massage device may adjust the characteristics of the second massage motion in response to the characteristics of the first massage motion analyzed in real time.

Adjustment of the characteristics of the second massage operation will be described in more detail with reference to the following figures 31 to 42.

Thereafter, the massage device may perform the second massage operation according to the adjusted characteristics of the second massage operation according to step S3230.

3.3.2. Characteristics of sound source signals according to different massage movements

In one embodiment, as described above, the characteristics of the sonic vibration massage may be adjusted according to other massage operations other than the sonic vibration massage. This may be to reduce a user's sense of heterogeneity, which may be generated by simultaneously providing a plurality of types of massage, and to provide a comfortable massage.

In this case, the operation characteristics of the sonic vibration massage may be determined based on the sound source signal. That is, the multi-modal massage in which the different massages are synchronized can be provided by synchronizing the operation characteristics of the different massages with the sound source signal.

In one embodiment, as described in FIG. 22 , the start time and end time of the movement pattern of the sonic vibration module and the start and end time of the vibration pattern of the sonic vibration massage at least partially coincide, thereby providing a comfortable massage to the user. can And, for this, the period of the synchronization waveform of the sound source signal may be n times or 1/n times the movement period of the sound wave vibration module.

This can also be applied to the operation characteristics of massage other than vibration massage. For example, the movement period of the sound wave vibration module of FIG. 22 (a) may be replaced with the movement period of the motion massager. Motion massage may be provided to the user according to the movement period of the motion massage member, and accordingly, the start and end points of the movement pattern of the motion massage member and the start and end points of the vibration pattern of the sonic vibration massage are at least partially When matched, a comfortable massage can be provided to the user. And, when the period of the synchronization waveform of the sound source signal is n times or 1/n times the movement period of the motion massage member, the start time and end time of the movement pattern of the motion massage member, the start time of the vibration pattern of the sound wave vibration massage, and The end time points may at least partially coincide.

In addition, according to the embodiment, the sound wave vibration module and other massage members may move in conjunction with each other. In this case, the movement of the other massage member, that is, the movement of the sound wave vibration module may be determined by another massage operation. It can also be applied to the relationship between the period and the synchronization waveform of the sound source signal.

Hereinafter, in order to describe in more detail, the relationship between various operations of motion massage and sonic vibration massage will be described.

3.3.3. Vibration massage action according to tapping massage action

In an embodiment, when the tapping massage is performed using the motion massage member, the massage device may provide the sonic vibration massage in response to the characteristics of the tapping massage. To this end, the massage device may perform sonic vibration massage by using a sound source signal corresponding to the characteristics of the tapping massage. Hereinafter, a sound source signal corresponding to the characteristics of the tapping massage will be described.

31 is a graph for explaining a sound source signal corresponding to a tapping massage according to an embodiment.

Referring to FIG. 31 , (a) may indicate a synchronization waveform of a sound source signal, (b) may indicate a vibration waveform of the sound source signal, and (c) may indicate a synchronization waveform and a sound source waveform based on the vibration waveform. Also, in (a) to (c), the x-axis may represent time, and the y-axis may represent amplitude.

In an embodiment, when the motion massage member performs the tapping massage, the motion massage member may perform a reciprocating motion in the z-axis direction. That is, when the movement length in the z-axis of the motion massage member is long, that is, when the motion massage member advances in the z-axis, it is strongly in contact with the user, and when the movement length in the z-axis is short, that is, the massage device moves to the z-axis. There may or may not be slight contact with the user when reversing on the axis.

The massage device may synchronize the intensity of the sonic vibration massage by synchronizing with the time when the motion massage member is moved in the z-axis.

In one embodiment, the massage device may increase the intensity of the sonic vibration massage when the motion massage member moves in the z-axis for a long length, and may decrease the intensity of the sonic vibration massage when the motion massage member moves in the z-axis when the length of movement in the z-axis is short. have. This may be to increase the effect of the tapping massage by providing the sonic vibration massage with the same intensity at the same time as the tapping massage.

In (a), the synchronization waveform may be a square waveform. Also, waveforms of different amplitudes may appear alternately. This may be to alternately control the intensity of the sonic vibration massage in synchronization with the tapping massage to provide the sonic vibration massage. In the example of (a), each waveform is illustrated as having one amplitude for convenience of explanation, but each waveform may have a plurality of amplitudes. In this case, the representative amplitudes of the respective waveforms may be different from each other. Here, the representative amplitude may mean an amplitude capable of representing a plurality of amplitudes included in each waveform, such as an average value, a mode value, and a maximum value of a plurality of amplitudes included in each waveform. The concept of the representative amplitude may be applied not only to the description of FIG. 31 but also to the entire specification.

In one embodiment, the massage device may control a waveform with a high amplitude to be located at a time point when the motion massage member moves in the z-axis is long, and the massage device has an amplitude at a point in time when the motion massage member moves in the z-axis is short. You can control this short waveform to be positioned. Of course, the present invention is not limited thereto, and the massage device may control a waveform having a high amplitude to be positioned at a point in time when the motion massage member moves in the z-axis at a short time, and the massage device at a point in time when the motion massage member moves in the z-axis is long. It can be controlled so that a waveform with a short amplitude is located in the

As shown in (b), the vibration waveform of the sound source signal may be configured with a constant frequency regardless of the position of the motion massage member. In the example of (b), the vibration waveform may be a sine wave. Of course, the present invention is not limited thereto, and the vibration waveform may be various waveforms other than a sine wave.

As the synchronization waveform of (a) and the vibration waveform of (b) are synthesized, the amplitude of the sound source signal is the same as in (c), but the vibration frequency may be the same for each waveform. The massage device may perform sonic vibration massage synchronized with the motion massage operation based on the sound source signal of (c).

Further, in another embodiment, the massage device may perform a sound wave vibration massage synchronized with a motion massage operation based on sound source signals having the same amplitude of detailed waveforms included in the sound source waveform, but different vibration frequencies. In this case, the massage device may control a waveform of a low vibration frequency to be located at a point in time when the motion massage member moves along the z-axis is long, and the massage device vibrates at a high vibration when the motion massage member moves in the z-axis is short. The frequency waveform can be controlled to be positioned. Of course, the present invention is not limited thereto, and the massage device may control a waveform of a high vibration frequency to be located at a point in time when the motion massage member moves in the z-axis with a long length, and the massage device includes a motion massage member with a short moving length in the z-axis. It can be controlled so that the waveform of the low vibration frequency is located at the time point. Accordingly, the massage device may enhance the effect of the tapping massage by providing the sonic vibration massage having an intensity corresponding to the movement length of the motion massage member in the z-axis. Also, in the above example, although the detailed waveforms have been described as having one frequency, each waveform may have a plurality of frequencies. In this case, the representative frequencies of the respective waveforms may be different from each other. Here, the representative frequency may mean an amplitude capable of representing a plurality of frequencies included in each waveform, such as an average value, a mode value, a maximum value, and the like of a plurality of frequencies included in each waveform. The concept of the representative frequency may be applied not only to the description of FIG. 31 but also to the entire specification.

32 is a diagram for explaining a sound source signal corresponding to a tapping massage according to another embodiment.

Referring to FIG. 32 , (a) is a diagram for explaining the positional relationship between a motion massage member and a sound wave vibration module according to a tapping massage, and (b) is a diagram illustrating a position in the z-axis of a motion massage member according to a tapping massage. It is a drawing. (c) shows the synchronization waveform of the sound wave vibration module according to the tapping massage, and (d) is a diagram showing the sound source waveform of the sound wave vibration module according to the tapping massage. In (b), the x-axis may represent time, and the y-axis may represent a position on the z-axis. In (c) and (d), the x-axis may represent time, and the y-axis may represent amplitude.

As in (a), the motion massage member and the sonic vibration module may be connected through a connection part. For example, the motion massage member may be located above the connection part, and the sound wave vibration module may be located below the connection part.

As in (a) and (b), the massage member may move long along the z-axis during the time period T2 to strongly contact the user. At this time, the sonic vibration module connected to the connection part moves relatively short along the z-axis compared to the motion massage member during the time period T2, and accordingly, the sonic vibration module may or may not be in contact with the user. In addition, after the motion massage member moves along the z-axis for a long time, the motion massage member may move briefly along the z-axis during the time period T1 to weakly or not contact the user. At this time, the sound wave vibration module moves relatively long in the z-axis compared to the motion massage member during the time period T1, and accordingly, the sound wave vibration module may be in strong contact with the user.

When the tapping massage operation is performed, the massage device may provide the sonic vibration massage synchronized to the positions of the motion massage member and the sonic vibration module. To this end, the massage device may perform sonic vibration massage by using a sound source signal corresponding to the tapping operation.

Specifically, when the tapping massage operation is performed, the synchronization waveform of the sound source signal may be in the form of alternating a first synchronization waveform with a small amplitude and a second synchronization waveform with a large amplitude as shown in (c). At this time, the first synchronization waveform with a small amplitude appears during the time period T2, which is a time period in which the motion massage member is in stronger contact with the user than the sound wave vibration module, and is a time period in which the motion massage member is in weak contact with the user than the sound wave vibration module. A second synchronization waveform having a large amplitude may be displayed during T1. Accordingly, as shown in (d), a first sound source waveform having a small amplitude may appear during a time period T2 and a second sound source waveform having a large amplitude may appear during a time period T1 as shown in (d).

When the massage device performs sonic vibration massage according to the sound source signal, when the motion massage member is in strong contact and the sonic vibration module is in weak contact, the sonic vibration massage of weak intensity may be performed. In addition, when the motion massage member is in weak contact and the sound wave vibration module is in strong contact, sonic vibration massage of high intensity may be performed. In this way, as the motion massage member provides a motion massage with a strong intensity and then provides a sonic vibration massage with a strong intensity, it is possible to continuously provide a massage with a strong intensity to the user. In addition, by providing a strong sonic vibration massage when the sonic vibration module is in strong contact, and providing a sonic vibration massage having a weak strength when the sonic vibration module is in weak contact, it is possible to increase the efficiency of the sonic vibration massage.

33 is a graph for explaining a sound source signal corresponding to a tapping massage according to another embodiment.

Referring to FIG. 33 , (a) and (b) may represent a sound source signal applied to a sound wave vibration module when a tapping massage is provided. The x-axis of (a) and (b) may represent time, and the y-axis may represent amplitude.

In one embodiment, the speed of the tapping massage may vary. For example, the massage device may perform the tapping massage at a first speed, and may perform the tapping massage at a second speed faster than the first speed. In this case, the moving speed of the motion massage member and the moving time of the sound wave vibration module may vary according to the speed of the tapping massage, and accordingly, the sound source waveform may also vary.

For example, if the speed of the tapping massage is a relatively slow first speed, the sound source waveform may appear in the form of alternating a first waveform with a relatively low amplitude and a second waveform with a relatively high amplitude as shown in (a). . And, when the speed of the tapping massage is the second speed faster than the first speed, the sound source waveform may appear in the form of alternating a third waveform with a relatively low amplitude and a fourth waveform with a relatively high amplitude as shown in (b). . In this case, the number of the third waveform and the fourth waveform may be greater than the number of the first waveform and the second waveform. This may be due to an increase in the number of times that the motion massage member and the sound wave vibration module strongly contact the user as the speed of the tapping massage increases. Also, the lengths of the third and fourth waveforms (ie, the duration of each waveform) may be shorter than the first and second waveforms. This may be due to a reduction in the contact time when the motion massage member and the sonic vibration module make one contact with the user.

However, in this case, the vibration frequencies of the first to fourth waveforms may all be the same. This may be to reduce the user's sense of heterogeneity by providing the sonic vibration massage with the same vibration frequency even if the speed of the tapping massage is changed. Of course, the present invention is not limited thereto, and according to embodiments, the vibration frequency may be changed when the speed of the tapping massage is changed.

3.3.4. Vibration massage action according to acupressure massage action

In one embodiment, when acupressure massage is performed using a motion massage member, the massage device may provide a sonic vibration massage in response to the characteristics of the acupressure massage. To this end, the massage device may perform a sonic vibration massage by using a sound source signal corresponding to the characteristics of the acupressure massage. Hereinafter, a sound source signal corresponding to the characteristics of acupressure massage will be described.

34 is a graph for explaining a sound source signal corresponding to acupressure massage according to an embodiment.

Referring to Figure 34, (a) is a view showing the position on the z-axis of the motion massage member according to the acupressure massage, (b) shows the synchronization waveform of the sound wave vibration module according to the acupressure massage, (c) is acupressure It is a diagram showing the sound source waveform of the sound wave vibration module according to the massage. In (a), the x-axis may represent time, and the y-axis may represent a position on the z-axis. In (b) and (c), the x-axis may represent time, and the y-axis may represent amplitude.

As described above, the acupressure massage may refer to a massage in which a kneading massage is performed when the applicator is advanced in the z-axis direction while slowly performing a tapping massage to perform a massage while continuously pressing the user. Accordingly, when acupressure massage is performed, the motion massage member maintains the advanced state in the z-axis direction as in (a) for a relatively long time period, time period T2, in the x-axis direction and/or the y-direction. You can go to and perform acupressure massage.

At this time, when the motion massage member may be located on the upper side of the connection part, and the acoustic vibration module is located on the lower side of the connection part, the acoustic vibration module may be in a backward state in the z-axis direction during the time period T2.

In addition, after the time period T2 ends, the motion massage member may maintain a backward state in the z-axis direction for a relatively short time period T1. At this time, the acoustic vibration module may be in a state advanced in the z-axis direction during the time period T1.

In one embodiment, when the acupressure massage operation is performed, the massage device may provide a sonic vibration massage synchronized to the positions of the motion massage member and the sonic vibration module. To this end, the massage device may perform a sonic vibration massage by using a sound source signal corresponding to the acupressure massage operation.

Specifically, the synchronization waveform of the sound source signal may have a form in which a first synchronization waveform having a small amplitude and a second synchronization waveform having a large amplitude are alternated as in (b). In this case, compared to the tapping massage, when performing acupressure massage, the time for the motion massage member to strongly contact the user and the time for the sound wave vibration module to lightly contact or not contact the user may be increased. Accordingly, a second synchronization waveform having a small amplitude may appear during the time period T2, and a first synchronization waveform having a high amplitude may appear during the time period T1. Also, as shown in (c), a first sound source waveform having a small amplitude may appear during the time period T2, and a second sound source waveform having a large amplitude may appear during the time period T1. In this case, as the time period T2 is longer than the time period T1, the length of the second synchronization waveform may be longer than the length of the first synchronization waveform.

As described above, when the motion massage member performs the acupressure massage with a strong intensity, the sonic vibration massage with a weak intensity is performed, and when the motion massage member performs the acupressure massage with a weak intensity, the sonic vibration massage with a strong intensity can be performed. Accordingly, after the high-intensity motion massage is performed, as the strong-intensity sonic vibration massage is provided, it is possible to continuously provide a massage of a specific intensity to the user. In addition, by providing a low-intensity sonic vibration massage when a high-intensity acupressure massage is performed, it is possible to focus more on the acupressure massage by the motion massage member.

35 is a graph for explaining a sound source signal corresponding to acupressure massage according to another embodiment.

Referring to FIG. 35, (a) may represent a synchronization waveform of a sound source signal when acupressure massage is provided, and (b) may represent a sound source waveform of a sound source signal when acupressure massage is provided.

In (a) and (b), time intervals T1, T3, T5, and T7 may be time intervals when the motion massage member moves backward to the user in the z-axis and the sonic vibration module advances in the z-axis, and time interval T2 , T4, and T6 may represent time sections when the motion massage member advances to the user in the z-axis and the sound wave vibration module moves backward in the z-axis.

In an embodiment, the representative amplitudes of the synchronization waveform and the sound source waveform in the time sections T1, T3, T5, and T7 may be higher than the representative amplitudes of the synchronization waveform and the sound source waveform in the time sections T2, T4, and T6. This may be to allow the user to focus on acupressure massage by the motion massage member according to the time sections T2, T4, and T6 in which the acupressure massage is performed by the motion massage member.

In addition, since the time of strong contact of the motion massage member to the user when the acupressure massage is performed is longer than the time of weak contact, the length of the synchronization waveform and the sound source waveform in the time sections T2, T4, and T6 is determined in the time sections T1, T3, It may be longer than the length of the synchronization waveform and the sound source waveform in T5 and T7.

Also, in an embodiment, the amplitudes of the synchronization waveform and the sound source waveform are not fixed but may be varied. This may be to provide a dynamic massage to the user by providing the sonic vibration massage with various amplitudes.

Also, in an embodiment, the vibration frequencies of the synchronization waveform and the sound source waveform in time sections may be varied. For example, the vibration frequency of the synchronization waveform and the sound source waveform in the same time period may be changed with the lapse of time. This may also be to provide a dynamic massage to the user.

Also, in another embodiment, the vibration frequency of the synchronization waveform and the sound source waveform in time sections may be the same. This may be to reduce a user's sense of heterogeneity due to the simultaneous provision of the motion massage and the sonic vibration massage by providing the sonic vibration massage with the same vibration frequency.

3.3.5. Vibration massage motion according to repeated massage motion

In an embodiment, when the massage is performed using a motion massage member, the massage device may provide a sonic vibration massage in response to the characteristics of the massage. To this end, the massage device may perform a sonic vibration massage by using a sound source signal corresponding to the characteristics of the repeated massage. Hereinafter, a sound source signal corresponding to the characteristics of the massage batter will be described.

36 is a graph for explaining a sound source signal corresponding to a massage batter according to an embodiment.

Referring to Figure 36, (a) is a view showing the position on the z-axis of the motion massage member according to the massage batter, (b) shows the synchronization waveform of the sound wave vibration module according to the massage batter, (c) is the batter It is a diagram showing the sound source waveform of the sound wave vibration module according to the massage. In (a), the x-axis may represent time, and the y-axis may represent a position on the z-axis. In (b) and (c), the x-axis may represent time, and the y-axis may represent amplitude.

As described above, the continuous tapping massage may refer to a massage in which a tapping massage is performed at a high speed in order to provide a high speed massage to a local body part. Accordingly, when the continuous massage is performed, the motion massage member rapidly alternates between the advanced state and the backward state in the z-axis direction as in (a), and the motion massage member moves backward in the z-axis direction for a relatively long time. After maintaining the state in which the motion massage member is moved forward in the z-axis direction, a state in which it is advanced and a state in which it is reversed may be rapidly alternated. At this time, in the state in which the motion massage member is advanced in the z-axis direction, the length of the motion massage member in the z-axis direction may be slightly different. For example, the length in the z-axis direction of the motion massage member when the motion massage member advances the second time in the z-axis direction is the length in the z-axis direction of the motion massage member when the motion massage member first advances in the z-axis direction. may be less than the length. This may be to provide a motion massage with various sensations to the user by differentiating the stimulation intensity according to the motion massage member.

In addition, the motion massage member may be located on the upper side of the connection part, and when the sonic vibration module is located on the lower side of the connection part, when the motion massage member is advanced in the z-axis, the sonic vibration module may move backward in the z-axis. have.

In one embodiment, when a continuous massage operation is performed, the massage device may provide a sonic vibration massage synchronized to the position of the motion massage member and the sonic vibration module. To this end, the massage device may perform a sonic vibration massage by using a sound source signal corresponding to a continuous massage operation.

As in the above-mentioned tapping massage and acupressure massage, even in the case of continuous hitting massage, when the motion massage member advances in the z-axis and the sound wave vibration module moves backward in the z-axis, the synchronization waveform of (b) and (c) and the sound source waveform The amplitude may be relatively small, and when the motion massage member moves backward in the z-axis and the sound wave vibration module advances in the z-axis, the amplitudes of the synchronization waveform and the sound source waveform in (b) and (c) may be relatively large. Accordingly, when the repeated massage is performed, in the synchronization waveform and the sound source waveform, a waveform having a relatively large amplitude and a waveform having a relatively small amplitude may appear alternately. However, in a state in which the motion massage member is advanced in the z-axis direction, since the length in the z-axis direction of the motion massage member may be slightly different, the amplitudes of the waveforms having relatively small amplitudes may be slightly different. Accordingly, the massage device may provide a sonic vibration massage synchronized to the continuous massage.

37 is a graph for explaining a sound source signal corresponding to a massage batter according to another embodiment.

Referring to FIG. 37, (a) may represent a synchronization waveform of the sound source signal when the massage is provided, (b) may represent the waveform of the sound source signal when the massage is provided.

In (a) and (b), time sections T1, T3, T6, and T8 may be time sections when the motion massage member moves backward to the user in the z-axis and the sonic vibration module advances in the z-axis, and time section T2 , T4, T5, and T7 may represent time sections when the motion massage member advances to the user in the z-axis and the sound wave vibration module moves backward in the z-axis.

In an embodiment, the representative amplitudes of the synchronization waveform and the sound source waveform in the time sections T1, T3, T6, and T8 may be higher than the representative amplitudes of the synchronization waveform and the sound source waveform in the time sections T2, T4, T5, and T7. This may be for the purpose of allowing the user to focus on the massage by the motion massage member according to the time interval T2, T4, T5, T7 is a section in which the massage by the motion massage member is performed.

Also, in an embodiment, the amplitudes of the synchronization waveform and the sound source waveform are not fixed but may be varied. This may be to provide a dynamic massage to the user by providing the sonic vibration massage with various amplitudes.

In addition, in one embodiment, as in acupressure massage, the vibration frequency of the synchronization waveform and the sound source waveform in time sections may be variable or may be fixed.

3.3.6. Vibration massage motion according to sweep massage motion

In an embodiment, when sweeping massage is performed using a motion massage member, the massage device may provide a sonic vibration massage in response to the characteristics of the sweeping massage. To this end, the massage device may perform the sonic vibration massage by using a sound source signal corresponding to the characteristics of the sweeping massage. Hereinafter, a sound source signal corresponding to the characteristics of the sweep massage will be described.

38 is a graph for explaining a sound source signal corresponding to a sweep massage according to an embodiment.

Referring to FIG. 38 , (a) shows the position on the z-axis of the motion massage member according to the battered massage, (b) shows the position on the y-axis of the motion massage member according to the battered massage, (c) shows the sweep It shows the synchronization waveform of the sound wave vibration module according to the massage, (d) is a diagram showing the sound source waveform of the sound wave vibration module according to the sweep massage. In (a) and (b), the x-axis may represent time, and the y-axis may represent a position on the z-axis. In (c) and (d), the x-axis may represent time, and the y-axis may represent amplitude.

As described above, the sweeping massage may refer to a massage performed while moving the applicator in the y-axis direction when the applicator is advanced in the z-axis direction in order to provide a high-speed massage to a wide body range.

Accordingly, when the sweep massage is performed, as in (a) and (b), when the motion massage member is advanced in the z-axis, it moves to a low position along the y-axis, and then moves to a high position on the y-axis again. have. In this case, the positional movement of the motion massage member along the y-axis may be performed at a relatively high speed. This may be to provide a massage to a wide area within a short time through the rapid movement of the motion massage member.

As such, as the motion massage member rapidly moves along the y-axis in the sweep massage, the intensity of stimulation by the motion massage member may be relatively low. In this case, in order to synchronize the intensity of the sweep massage and the sonic vibration massage, the intensity of the sonic vibration massage provided together with the sweep massage may be adjusted to be relatively low.

More specifically, as in (c) and (d), the synchronization waveform and the sound source waveform of the sound source signal exhibit a long parabolic shape, and the difference between the largest amplitude and the smallest amplitude in the synchronization waveform is set within a predetermined difference. can This is because in the sweep massage, the intensity of stimulation by the motion massage member may not vary depending on the position of the motion massage member. In addition, according to an embodiment, the synchronization waveform may have a straight line shape with no change in amplitude.

Of course, according to embodiments, the intensity of stimulation by the motion massage member in the sweep massage may be varied according to the position of the motion massage member. In this case, in response to the intensity of stimulation by the motion massage member, the amplitude of the synchronization waveform may also be adjusted.

In addition, according to an embodiment, the intensity of stimulation provided by the motion massage member and the sonic vibration module may vary according to body parts in contact with the motion massage member and the sonic vibration module. This is because the required stimulation intensity may be different for each body part. In this case, the amplitude of the synchronization waveform may be adjusted to provide an appropriate stimulation intensity by sonic vibration massage for each body part.

In addition, in one embodiment, as in acupressure massage, the vibration frequency of the synchronization waveform and the sound source waveform may be variable or may be fixed. When the vibration frequency of the synchronization waveform and the sound source waveform is changed, the stimulation intensity by the sound wave vibration massage may be adjusted by adjusting the vibration frequency.

3.3.7. Vibration massage action according to the kneading massage action

In an embodiment, when the kneading massage is performed using the motion massage member, the massage device may provide the sonic vibration massage in response to the characteristics of the kneading massage. To this end, the massage device may perform sonic vibration massage using a sound source signal corresponding to the characteristics of the kneading massage. Hereinafter, a sound source signal corresponding to the characteristics of the kneading massage will be described.

39 is a graph for explaining a sound source signal corresponding to a kneading massage according to an embodiment.

Referring to FIG. 39 , (a) may represent a synchronization waveform of a sound source signal, (b) may represent a vibration waveform of a sound source signal, and (c) may represent a sound source waveform in which a synchronization waveform and a vibration waveform are synthesized. Also, in (a) to (c), the x-axis may represent time, and the y-axis may represent amplitude.

In an embodiment, the kneading massage may refer to a massage that provides stimulation of a predetermined strength or more to the user through movement of the motion massage member while the motion massage member is in contact with the user's body. For example, as described above, when the user is located in the z-axis direction with respect to the massage unit, the kneading massage is performed by moving the motion massage member in the x-axis direction and/or the y-axis direction after the motion massage member is moved in the z-axis direction. can provide Of course, the motion massage member may move in the z-axis direction while the kneading massage is performed.

In one embodiment, the massage device may synchronize the intensity of the sonic vibration massage by synchronizing with the time when the motion massage member is moved in the x-axis direction and/or the y-axis direction.

In one embodiment, the massage device may move the motion massage member in the x-axis direction and the y-axis direction according to various trajectories such as a circle, a semicircle, an ellipse, and a quadrant. In this case, the intensity of the massage stimulation may be varied according to the trajectory of the motion massage member. For example, when the motion massage member is moved according to the circular trajectory, when the motion massage member draws a semicircle from the initial position to the first position, the massage stimulation intensity may be increased according to the trajectory of the motion massage member, and the motion massage member When a semicircle is drawn from the first position to the initial position while returning, the massage stimulation intensity may be reduced in the trajectory of the motion massage member. In one embodiment, by moving the motion massage member along a predetermined trajectory so that the intensity of massage stimulation is varied, the user's contact area may be confirmed in advance. In this case, the massage device may control the movement trajectory of the motion massage member so that strong stimulation is applied to a specific body part requiring strong stimulation.

In addition, in one embodiment, the varying intensity of the massage stimulation may be due to the characteristics of the user's body part to which the motion massage member is in contact. For example, the inner portion than the outer portion of the user's back may protrude toward the massage device, and accordingly, even if the motion massage member moves by the same length in the z-axis, the stimulation intensity of the massage applied to the inner portion of the user's back can be high

In addition, the massage device may control the intensity of the sound wave vibration module massage in response to the intensity of massage stimulation applied to the user by the motion massage member. For example, when the massage stimulation intensity by the motion massage member is high, the intensity of the sonic vibration module massage can be controlled high, and when the massage stimulation intensity by the motion massage member is low, the intensity of the sonic vibration module massage can be controlled low. have. This may be to enhance the effect of the kneading massage by providing the sonic vibration massage with the same intensity at the same time as the kneading massage.

In (a), the synchronization waveform may be a mixture of the first to third waveforms. The first synchronization waveform may have a form in which the amplitude is increased and then decreased, the second synchronization waveform is a form in which the amplitude is maintained, and the third synchronization waveform is a form in which the amplitude is increased and then decreased.

In one embodiment, when the massage device performs the kneading massage, the intensity of the massage stimulation by the motion massage member is increased and decreased during the first time period, the movement of the motion massage member is stopped during the second time period, and the third During the time period, the intensity of massage stimulation by the motion massage member may be increased and then decreased again. The synchronization waveform of (a) is for controlling the sound wave vibration module in response to the pattern of the kneading massage, applying a first synchronization waveform during a first time period, and applying a second synchronization waveform during a second time period, A third synchronization waveform may be applied during the third time period.

In addition, as shown in (b), the vibration waveform of the sound source signal may be configured with a constant frequency regardless of the position of the motion massage member. In the example of (b), the vibration waveform may be a sine wave. Of course, the present invention is not limited thereto, and the vibration waveform may be various waveforms other than a sine wave.

As the synchronization waveform of (a) and the vibration waveform of (b) are synthesized, a sound source waveform as shown in (c) may appear. According to the sound source waveform, the massage device increases and then decreases the amplitude of the sound wave vibration module for the first time period, maintains the amplitude of the sound wave vibration module for the second time period, and the third time period is the amplitude of the sound wave vibration module can be increased and then decreased. Accordingly, the massage device may perform the sonic vibration massage synchronized with the kneading massage of the motion massage member.

40 is a diagram for explaining a sound source signal corresponding to a kneading massage according to another embodiment.

Referring to FIG. 40 , (a) is a diagram for explaining a movement trajectory of a motion massage member according to a kneading massage, and (b) is a diagram illustrating a position on the y-axis of a motion massage member according to a kneading massage. (c) shows the synchronization waveform of the sound wave vibration module according to the kneading massage, (d) is a diagram showing the sound source waveform of the sound wave vibration module according to the kneading massage. In (b), the x-axis may represent time, and the y-axis may represent a position on the y-axis of the motion massage member. In (c) and (d), the x-axis may represent time, and the y-axis may represent amplitude.

As in (a), the motion massage member and the sonic vibration module may be connected through a connection part. For example, the motion massage member may be located above the connection part, and the sound wave vibration module may be located below the connection part. Hereinafter, for convenience of explanation, the motion massage member moves along a circular trajectory, and a pair of motion massage members and sound wave vibration modules among the two pairs of motion massage members and sound wave vibration modules shown in (a) will be described as a reference.

In addition, as in (a) and (b), when the motion massage member moves according to a circular trajectory, the position of the motion massage member during the time period T1 increases and then decreases in the y-axis, and the motion massage member during the time period T1 The position of may be substantially increased with respect to the x-axis. In this case, the intensity of massage stimulation by the motion massage member may be increased. Also, during the time period T2, the position of the motion massage member is decreased on the y-axis and then increased, and during the time period T1, the position of the motion massage member is generally decreased with respect to the x-axis. In this case, the intensity of massage stimulation by the motion massage member may be reduced.

When the kneading massage operation is performed, the massage device may provide the sonic vibration massage synchronized to the positions of the motion massage member and the sonic vibration module. To this end, the massage device may perform sonic vibration massage using a sound source signal corresponding to the kneading motion.

Specifically, when the kneading massage operation is performed, the amplitude of the synchronization waveform of the sound source signal may increase during the time period T1 and decrease during the time period T2 as shown in (c). That is, the synchronization waveform may include a first detailed synchronization waveform whose amplitude increases during the time period T1 and a second detailed synchronization waveform whose amplitude decreases during the time period T2. In this case, as the time period T2 continuously arrives after the time period T1 has elapsed, the first detailed synchronization waveform and the second detailed synchronization waveform may be continuously connected.

Also, as shown in (d), the amplitude of the sound source waveform of the sound source signal may increase during the time period T1, and the amplitude may decrease during the time period T2. Similar to the synchronization waveform, the sound source waveform may include a first detailed sound source waveform whose amplitude is increased during the time period T1 and a second detailed sound source waveform whose amplitude is decreased during the time period T2. For example, the first detailed sound source waveform and the second detailed sound source waveform may be continuously connected. Of course, in another example, the first detailed sound source waveform and the second detailed sound source waveform are not continuously connected, and another waveform may be included between the first detailed sound source waveform and the second detailed sound source waveform.

The appearance of the first detailed sound source waveform with increasing amplitude during time period T1 and the appearance of the second detailed sound source waveform with decreasing amplitude during time period T2 means that the massage stimulation intensity by the motion massage member increases during time period T1, and time It can be attributed to the decrease during interval T2. That is, the amplitude of the sound source waveform may be adjusted in response to the intensity of massage stimulation by the motion massage member.

Further, in another embodiment, the massage device may perform a sound wave vibration massage synchronized with a motion massage operation based on sound source signals having the same amplitude of detailed waveforms included in the sound source waveform, but different vibration frequencies. In this case, the massage device controls the frequency of the detailed waveform to decrease during the time period T1 in which the massage stimulation intensity by the motion massage member is increased, and the frequency of the detailed waveform during the time period T2 in which the massage stimulation intensity by the motion massage member is decreased. can be controlled to increase.

Of course, the present invention is not limited thereto, and the massage device controls the frequency of the detailed waveform to increase during the time period T1 in which the massage stimulation intensity by the motion massage member is increased, and during the time period T2 in which the massage stimulation intensity by the motion massage member is decreased. It is possible to control the frequency of the detailed waveform to be lowered. Accordingly, the massage device can enhance the effect of the kneading massage by providing the sonic vibration massage having an intensity corresponding to the massage stimulation intensity by the motion massage member.

Also, in one embodiment, the speed of the kneading massage may vary. For example, the massage device may perform the kneading massage at a first speed, and may perform the kneading massage at a second speed faster than the first speed. In this case, the moving speed of the motion massage member and the moving time of the sound wave vibration module may vary according to the speed of the kneading massage, and accordingly, the sound source waveform may also vary.

For example, when the speed of the kneading massage is the first speed, the sound source waveform may appear as shown in (d), and when the speed of the kneading massage is the second speed faster than the first speed, time section T1 and time section T2 length may be shortened. This may be to increase the speed of the sonic vibration massage in response to the increased speed of the kneading massage and at the same time provide the sonic vibration massage corresponding to the stimulation intensity by the kneading massage.

In addition, as another example, when the speed of the kneading massage is changed, the sonic vibration massage may be provided using a sound source signal different from the existing sound source signal. For example, when the speed of the kneading massage is increased, it is possible to provide a sonic vibration massage at a faster speed by using a sound source signal of a sound source having a higher bpm than an existing sound source.

41 is a graph for explaining a sound source signal corresponding to a kneading massage according to another embodiment.

Referring to FIG. 41 , (a) may represent a synchronization waveform of a sound source signal when a kneading massage is provided, and (b) may represent a sound source waveform of a sound source signal when a kneading massage is provided.

In (a) and (b), the amplitudes of the synchronization waveform and the sound source waveform may continuously include a waveform that is increased and then decreased. This may be due to the stimulation intensity by the motion massage member being increased and then decreased when the kneading massage is provided.

Also, in (a) and (b), detailed waveforms included in the synchronization waveform and the sound source waveform may be slightly varied. This may be in order to provide a dynamic massage to the user by allowing the massage device to provide sonic vibration massage with various amplitudes.

Further, in one embodiment, the vibration frequency of the synchronization waveform and the sound source waveform may be variable or may be fixed.

42 is a graph for explaining a movement trajectory of a motion massage member when a kneading massage is provided according to an embodiment.

Referring to FIG. 42 , in (a) to (c), the x-axis may indicate time, and the y-axis may indicate a position on the y-axis of the motion massage member.

Specifically, when the kneading massage is provided, the motion massage member may reciprocate in a circular trajectory as in (a). That is, the massage device performs a first movement of moving the motion massage member from a first position to a second position, and moves from the second position to the first position according to a trajectory other than the trajectory of the first movement. A second movement may be performed. At this time, it may have a pattern in which the intensity of massage stimulation by the motion massage member increases and then decreases. Accordingly, when the massage device applies the sound source signal of FIG. 41 to the sound wave vibration module, sound wave vibration corresponding to the kneading massage Massage can be provided.

In addition, the motion massage member may reciprocate in a semicircular trajectory as in (b). That is, the massage device performs a first movement of moving the motion massage member from a first position to a second position, and performs a second movement of moving the motion massage member from the second position to the first position according to the trajectory of the first movement. can be done At this time, similar to the case where the motion massage member reciprocates in a circular trajectory, the massage stimulation intensity by the motion massage member may have a pattern in which it increases and then decreases, and accordingly, the massage device receives the sound source signal of FIG. When applied to the sonic vibration module, it is possible to provide a sonic vibration massage corresponding to the kneading massage.

However, in some cases, when the motion massage member reciprocates in a semicircular trajectory, the intensity of massage stimulation by the motion massage member may be weaker than when the motion massage member reciprocates in a circular trajectory. That is, as the motion massage member moves, a difference in massage stimulation intensity may be small. In this case, the massage device may provide the sonic vibration massage by using the sound source signal used for the sweep massage of FIG. 39 (d) rather than the sound source signal of FIG. 41 . Accordingly, the massage device may provide a sonic vibration massage corresponding to the kneading massage in which the deviation of the massage stimulation according to the movement of the motion massage member is small.

Also, the motion massage member may reciprocate in a quadrant trajectory as in (c). At this time, the massage device performs a first movement of moving the motion massage member from a first position to a second position, and performs a second movement of moving the motion massage member from the second position to the first position according to the trajectory of the first movement. can be done However, according to the embodiment, the length between the first position and the second position when the motion massage member moves in the circular trajectory and the semicircular trajectory is rather than the length between the first position and the second position when the motion massage member moves in the quadrant trajectory. distance can be short. Accordingly, the time for which the motion massage member moves may also be reduced. Also, a difference in massage stimulation intensity when the motion massage member moves in a quadrant trajectory may be smaller than a difference in massage stimulation intensity when the motion massage member reciprocates in a circular or semicircular trajectory. Even in this case, the massage device may provide the sonic vibration massage by using the sound source signal used for the sweep massage of FIG. 39 (d) rather than the sound source signal of FIG. 41 . Accordingly, the massage device may provide a sonic vibration massage corresponding to the kneading massage in which the deviation of the massage stimulation according to the movement of the motion massage member is small.

Of course, the present invention is not limited thereto, and even when the motion massage member moves in a quadrant trajectory according to an embodiment, a difference in massage stimulation intensity as the massage member moves may be large. In this case, the massage device may perform sonic vibration massage using the sound source signal of FIG. 41 . However, the length of the waveform included in the sound source signal may vary according to the time the motion massage member reciprocates.

In addition, according to the embodiment, when the motion massage member moves in a circular trajectory, a semi-circle trajectory and a quadrant trajectory, the massage device may be used for the sound source signal of FIG. A sound wave vibration massage may be provided using a sound source signal. Accordingly, the massage device may provide the user with sonic vibration massage of various feelings.

3.4. Provides vibration massage based on user's contact status

In one embodiment, the acoustic vibration module may be disposed in various positions of the massage device. For example, the acoustic vibration module may be disposed in various positions such as a seat part, an arm part, a leg part, as well as a massage module. In addition, the massage device may be implemented in various forms such as a car seat type, a bed type, and a sofa type as well as a chair type, and the sound wave vibration module may be disposed in various positions of various types of massage devices.

However, in some cases, the head of the sound wave vibration module may not come into contact with the user's body part. For example, when the massage device is a chair type and the acoustic vibration module is disposed on the leg portion of the massage device, the head of the acoustic vibration module may not contact the user when the user's height is small. In addition, when the massage device is a car seat type and the acoustic vibration module is in contact with the seat of the massage device, the acoustic vibration module may not contact the user depending on the driving posture of the user, and even when the user does not sit on the massage device, the acoustic vibration module The head of the vibration module may not be able to contact the user.

Meanwhile, the sound wave vibration module may use a sound source signal of an audible frequency band, and when outputting sound wave vibration, a sound may be generated from the sound wave vibration module according to the sound source signal.

However, when the head of the sound wave vibration module does not contact the user, the sound wave vibration may also not be transmitted to the user. In this case, the sound generated from the sound wave vibration module may act as noise to the user. In addition, when the head of the sound wave vibration module does not contact the user, the sound wave vibration module may output sound wave vibration meaninglessly, and durability of the sound wave vibration module may also be weakened due to the output of the sound wave vibration module.

To this end, the massage device may determine whether the user touches the sound wave vibration module and control the sound wave vibration massage based on this. It will be described in detail below.

43 is an operation flowchart for explaining a method of controlling a massage device according to an embodiment.

Referring to FIG. 43 , the control method of the massage device may include the step of confirming the user's contact strength with the sound wave vibration module (S4310) and the step of providing the sonic vibration massage based on the user's contact strength (S4320). have.

In step S4310, the massage device may check the intensity of the user's contact with the sound wave vibration module using the pressure sensor. The pressure sensor may be configured in various types such as mechanical, electronic, semiconductor, and the like. In addition, the pressure sensor may be configured in a thin film type. For example, the pressure sensor may include a Force Sensitive Resistor (FSR). Of course, in addition, the pressure sensor may include any sensors capable of confirming the strength of the user's contact with the acoustic vibration module.

In one embodiment, the pressure sensor may be attached to the head of the sonic vibration module.

Also, in another embodiment, the pressure sensor may be disposed under the acoustic vibration module. For example, when the acoustic vibration module is disposed on the seat of the massage device, the pressure sensor may be disposed between the acoustic vibration module and the seat. In addition to this, the pressure sensor may be disposed at any position where the user's contact strength with the sound wave vibration module can be checked.

In addition, as the intensity of the user's contact with the sound wave vibration module, the massage device may determine whether the user has contacted the sound wave vibration module and the contact strength when the user contacts the sound wave vibration module.

In one embodiment, when the pressure sensor is disposed on the head of the sound wave vibration module, the massage device determines whether the user has contacted the sound wave vibration module and the intensity of contact to the head when the user is in contact with the head of the sound wave vibration module can be checked

In addition, in one embodiment, the massage device may obtain information about the time the user is in contact with the sound wave vibration module and the non-contact time.

In addition, in step S4320, the massage device may provide a sonic vibration massage based on the user's contact strength. At this time, when a plurality of sound wave vibration modules are disposed in the massage device, the intensity of the user's contact with each sound wave vibration module may be different. In this case, the massage device may control each sound wave vibration module individually to control the sound wave vibration massage according to the user's contact strength with respect to each sound wave vibration module.

In one embodiment, the massage device may not output sound wave vibration using the sound wave vibration module when the user does not contact the sound wave vibration module or when it is determined that the user's contact strength to the sound wave vibration module is less than or equal to a predetermined strength have. This may be to remove unnecessary noise and prevent the durability of the acoustic vibration module from being weakened.

In addition, in another embodiment, the massage device, when the user does not contact the sound wave vibration module, or when it is determined that the user's contact strength to the sound wave vibration module is less than or equal to a predetermined strength, weakly control the output intensity of the sound wave vibration module. can For example, the massage device may set the amplitude of the sound wave vibration module to be smaller than a predetermined amplitude, or set the vibration frequency of the sound wave vibration module to be higher than a predetermined reference frequency. Alternatively, in some cases, the sound wave vibration may be output by using a pre-stored sound source signal used when the user does not come into contact with the sound wave vibration module. This may also be to reduce unnecessary noise and prevent the durability of the acoustic vibration module from being weakened.

In addition, in one embodiment, when the user is in contact with the sound wave vibration module or it is determined that the user's contact strength to the sound wave vibration module is equal to or greater than a predetermined strength, the massage device may output sound wave vibration using the sound wave vibration module. . In addition, according to the embodiment, the massage device may strongly control the output intensity of the sound wave vibration module. As described above, the massage device may set the amplitude of the sound wave vibration module to be greater than a predetermined amplitude, or set the vibration frequency of the sound wave vibration module to be smaller than a predetermined reference frequency. Alternatively, in some cases, the sound wave vibration may be output by using a pre-stored sound source signal used when the user makes contact with the sound wave vibration module. This may be in order to improve the effect of the sonic vibration massage on the user in contact with the sonic vibration module.

In addition, in another embodiment, the massage device may control the output intensity of the sound wave vibration module in response to the intensity of the user's contact with the sound wave vibration module. For example, as the intensity of the user's contact with the sound wave vibration module is higher, the massage device may output sound wave vibration of high output intensity. This is because the higher the intensity of the user's contact with the sonic vibration module, the higher the output intensity of the sonic vibration massage should be provided so that the effect of the sonic vibration massage can be improved.

In addition, in one embodiment, the massage device may control the output intensity of the sound wave vibration module based on the time the user does not contact the sound wave vibration module.

For example, the massage device may stop the output of the sound wave vibration module or weakly control the output intensity of the sound wave vibration module when the user's non-contact time with the sound wave vibration module is longer than a predetermined reference time. This is because, if the user controls the output of the sound wave vibration module even when the user does not contact the sound wave vibration module for a while, the user may feel a sense of heterogeneity, and an output change within a short time may put a burden on the sound wave vibration module.

In addition, in another example, the massage device weakly controls the output intensity of the sound wave vibration module when the user does not contact the sound wave vibration module, but the user does not contact the sound wave vibration module when the non-contact time is longer than a predetermined reference time. The output of the module can be stopped. This immediately reflects the vibration feedback according to whether the user has contacted the sonic vibration module, but if the user's non-contact time with the sonic vibration module is longer than the predetermined reference time, the user may not be willing to receive the sonic vibration massage. because there is

In addition, in one embodiment, the massage device may control the output intensity of the sound wave vibration module based on the time the user contacts the sound wave vibration module.

For example, the massage device may control the amplitude and/or the vibration frequency of the sound wave vibration module when the user's contact time with the sound wave vibration module is greater than or equal to a predetermined reference time. This may be to reduce such fatigue by providing the acoustic vibration massage with various amplitudes and/or vibration frequencies because the user may feel fatigue when the sonic vibration massage is continuously provided only to a specific body part.

3.5. Provides vibration massage in conjunction with multiple vibration modules

In one embodiment, a plurality of sound wave vibration modules may be disposed in the massage device, and the massage device may provide a sound wave vibration massage using the plurality of sound wave vibration modules.

Also, in one embodiment, the massage device may provide a sonic vibration massage in which a plurality of sonic vibration modules are interlocked. This may be to provide a sound wave vibration massage with a sense of unity by synchronizing the sound wave vibrations output from the plurality of sound wave vibration modules.

44 is an operation flowchart for explaining a method of controlling a massage device according to an embodiment.

Referring to Figure 44, the control method of the massage device includes the steps of confirming the characteristics of the first sonic vibration massage provided from the first sonic vibration module and/or the characteristics of the second sonic vibration massage provided from the second sonic vibration module ( S4410) and controlling the first sound wave vibration module and/or the second sound wave vibration module based on the identified characteristics (S4420).

In step S4410, the massage device may determine the amplitude, vibration frequency, output timing, etc. of the vibrations output from the first sound wave vibration module and the second sound wave vibration module as characteristics of the sound wave vibration massage. For example, the massage device may determine the characteristics of the sound wave vibration massage based on the sound source signal applied to the first sound wave vibration module and the second sound wave vibration module.

In addition, in one embodiment, the massage device may output the first sound wave vibration module, the second sound wave vibration module may not output. In this case, the massage device may check the characteristics of the first sonic vibration massage, but may not check the characteristics of the second sonic vibration massage that is not provided.

In step S4420, the massage device may control the first sound wave vibration module and/or the second sound wave vibration module based on the characteristics of the sound wave vibration massage confirmed in step S4410.

In one embodiment, the massage device may control the characteristics of the first sonic vibration massage and the second sonic vibration massage to be the same. For example, the massage device may control the amplitude, vibration frequency, output timing, and the like of the first sound wave vibration module and the second sound wave vibration module to be the same.

Also, in another embodiment, the massage device may adjust the characteristics of the second sonic vibration massage in response to the characteristics of the first sonic vibration massage. For example, the massage device may set the amplitude of the second sound wave vibration module to be high as the amplitude of the first sound wave vibration module increases, and as the vibration frequency of the first sound wave vibration module increases, the vibration of the second sound wave vibration module You can set the frequency higher. In addition, the massage device may set the amplitude of the second sound wave vibration module low or set the vibration frequency low even when the amplitude of the first sound wave vibration module is lowered or the vibration frequency is lowered.

Also, in one embodiment, the massage device may adjust the output timing of the first sound wave vibration module and the output timing of the second sound wave vibration module. For example, the massage device may adjust the output time of the first sound wave vibration module and/or the output time of the second sound wave vibration module so that the output of the first sound wave vibration module and the output of the second sound wave vibration module are alternately provided .

In addition, the output timing of the first sound wave vibration module and/or the second sound wave vibration module may be controlled so that the first sound wave vibration massage and the second sound wave vibration massage are provided according to a predetermined pattern.

In addition, in one embodiment, the massage device may provide a sonic vibration massage by setting the frequencies of the first sound wave vibration module and the second sound wave vibration module differently. This may be to provide sound wave vibration massage with various feelings by outputting sound wave vibrations of different frequencies.

For example, the massage device may set the vibration frequency of the second sound wave vibration module to be lower than the vibration frequency of the first sound wave vibration module. As a specific example, the first sound wave vibration module and the second sound wave vibration module may be disposed on the left and right sides of the massage module. At this time, when the vibration frequency of the second sound wave vibration module is set to be lower than the vibration frequency of the first sound wave vibration module, the sound wave vibration massage feeling that the vibration moves from one side to the other side may be provided. As another example, the first sound wave vibration module and the second sound wave vibration module may be disposed above and below the massage module. At this time, even when the vibration frequency of the second sound wave vibration module is set to be lower than the vibration frequency of the first sound wave vibration module, the sound wave vibration massage feeling that the vibration moves from one side to the other side may be provided.

Further, in another embodiment, the first sound wave vibration module and the second sound wave vibration module may be disposed on the left and right of the massage module. At this time, the first sound wave vibration module and the second sound wave vibration module may move left and right, and accordingly, the distance between the first sound wave vibration module and the second sound wave vibration module may increase and then move away. The massage device may set the vibration frequency of the second sound wave vibration module to be lower than the vibration frequency of the first sound wave vibration module when the distance between the first sound wave vibration module and the second sound wave vibration module is within a predetermined reference distance. This is because, when the distance between the first sonic vibration module and the second sonic vibration module is close, the difference between the first sonic vibration massage and the second sonic vibration massage due to different vibration frequencies may be well felt by the user.

In addition, in one embodiment, the massage device may provide a sonic vibration massage by independently controlling a plurality of sonic vibration modules.

For example, a body part of a user that comes into contact with each of the acoustic vibration modules may be different. By independently controlling the plurality of sound wave vibration modules, the massage device may provide a sound wave vibration massager suitable for the user's body part to which each of the plurality of sound wave vibration modules is in contact with the corresponding body part.
