5 to 14 are views for explaining each part of the speaker module. Hereinafter, description of the above-described parts may be omitted.

First, referring to FIGS. 5 to 6 attached to the case portion 10 is as follows.

Referring to Figure 5, the case portion 10 may include a body portion (Body Part, 100) having a cylindrical shape with both sides open.

The width W1 in the first direction DR1 and the width W2 in the second direction DR2 of the body portion 100 of the case portion 10 are the width W3 in the third direction DR3, That is, it can be larger than the height. In other words, the widths W1 and W2 of the case portion 10 may be greater than the height W3.

In this case, it may be possible to place the speaker module 10A according to the present invention under the user's bed. Accordingly, sleep induction efficiency may be further improved.

A first protrusion 110 and a second protrusion 120 protruding toward the center of the body portion 100 may be formed on an inner side surface of the body portion 100 of the case portion 10.

Here, the first protrusion 110 and the second protrusion 120 may be formed in a form that surrounds the inside of the body portion 100.

The first protrusion 110 may correspond to the edge of the first vibrating plate 20, and the second protrusion 120 may correspond to the edge of the second vibrating plate 30.

Looking at the cross-section of the main body 100, as in the case of FIG. 6, the second protrusion 120 is located in front of the main body 100, that is, in front of the case portion 10, the first protrusion 110 May be located closer to the center of the body portion 100, that is, the center of the case portion 10 in the vertical direction, that is, in the third direction DR3, compared to the second protrusion 120.

Let the front end of the main body 100 be referred to as a first end (EP1), and the rear end of the main body 100 be referred to as a second end (EP2).

Here, the distance d1 between the first protrusion 110 and the second protrusion 120 in the third direction DR3 is different from the distance d2 between the first protrusion 110 and the second end EP2. You can.

In order to generate sound in the ultra-low frequency band more effectively and stably, it may be desirable to have a sufficiently large gap between the first diaphragm 20 and the second diaphragm 30. To this end, the distance d1 between the first protrusion 110 and the second protrusion 120 may be larger than the distance d2 between the first protrusion 110 and the second end EP2. .

Next, referring to FIGS. 7 to 10 attached to the first diaphragm 20, the second diaphragm 30, and the back plate 40 are as follows.

Referring to FIG. 7, a connection portion 32 may be disposed between the second vibration plate 30 and the body portion 100 of the case portion 10. For example, the connection part 32 may be located between the second protrusion 120 of the body part 100 and the second vibration plate 30.

The connection part 32 can sufficiently stably connect the second vibration plate 30 to the main body 100 without being disturbed by vibration of the second vibration plate 30, that is, vibration.

The back plate 40 may block the rear of the case portion 10. From another point of view, the back plate 40 may block the rear of the main body 100.

The back plate 40 may be desirable to have a sufficient thickness to effectively reflect the compressed / extended air generated by the vibration of the first diaphragm 20.

In consideration of this, the thickness t3 of the back plate 40 may be thicker than the thickness t1 of the first diaphragm 20 and the thickness t2 of the second diaphragm 30.

Meanwhile, the thickness t1 of the first diaphragm 20 and the thickness t2 of the second diaphragm 30 may be different.

Since the motor unit MT having a relatively large weight is disposed on the first diaphragm 20, it may be desirable that the mechanical stability is sufficiently large. In consideration of this, the thickness t1 of the first diaphragm 20 may be thicker than the thickness t2 of the second diaphragm 30.

Next, the motor unit MT will be described below with reference to FIGS. 11 to 12.

For example, as shown in FIG. 11, the electric cord COR that electrically connects the motor unit MT and the PCB includes a portion disposed on the front surface FS of the first diaphragm 20, and the first diaphragm ( 20) may pass through a space between the body portion 100 of the case portion 10 and reach the PCB.

11, the electrical cord COR may pass through a space between the second side SF2 of the first diaphragm 20 and the main body 100.

Referring to FIG. 12, the first space 50 is a space that reflects sound, that is, a space that reflects air compressed / extended by the first diaphragm 20 back toward the first diaphragm 20 and has a relatively high relationship none.

In consideration of this, the height G4 of the first space 50 may be smaller than the height G3 of the second space 51.

In addition, the height G2 of the motor unit MT may be greater than the gap G1 between the second vibration plates 30 at the end of the motor unit MT in the second space 51. In this case, it may be possible to use a motor unit MT having a sufficiently large output.

The speaker module 10A according to the present invention may further include additional components. For this, with reference to the accompanying drawings as follows.

13 to 14 are views for explaining another configuration of the speaker module. Hereinafter, description of the above-described parts may be omitted.

The weight 32 may be disposed (attached, adhered) to the front surface of the second vibration plate 30.

The weight 32 can control the vibration of the second diaphragm 30 to further stabilize the frequency of sound output from the speaker module 10A according to the present invention.

Referring to FIG. 14, the weight 32 may be at least partially overlapped with the motor unit MT in the third direction DR3. In this case, the frequency of the sound output from the speaker module 10A according to the present invention can be further stabilized.

Referring to FIG. 15, the speaker module 10A according to the present invention may further include at least one shock absorbing part (SAP).

The buffer part (SAP) is disposed at least on the rear edge of the case part 10A, and can block (suppress) transmission of vibration generated during driving to the floor.

To this end, the shock absorber (SAP) may include a material having elasticity, such as a rubber material or a resin material.

The band of the sound output from the auxiliary sound output unit 1A, that is, the band of the auxiliary wave may be higher than the band of sound output from the first diaphragm 20 and the second diaphragm 30.

From another point of view, the speaker module 10A constituted by the case part 10, the first diaphragm 20, the second diaphragm 30, and the back plate 40 is called a main speaker (10A), A separate speaker mounted on the main speaker may be referred to as an auxiliary sound output unit 1A.

Alternatively, the auxiliary sound output unit 1A may be referred to as an auxiliary speaker.

From the viewpoint of the main speaker 10A and the auxiliary speaker, a band of sound output from the main speaker 1A (speaker module) and a band of sound output from the auxiliary sound output unit 1A may be different. Preferably, the band of sound output from the main speaker 1A may be lower than the band of sound output from the auxiliary sound output unit 1A.

The speaker composed of the main speaker 10A and the auxiliary sound output unit 1A can be viewed as a 1.1CH speaker system.

Here, it can be seen that the main speaker 10A is in charge of 1.0 channel, and the auxiliary sound output unit 1A is in charge of 0.1 channel.

Hereinafter, the speaker module 10A and the auxiliary sound output unit 1A will be described separately.

For example, the first driving signal supply unit 610 may vibrate the first diaphragm 20 by supplying the first driving signal to the motor unit MT to generate a surface wave including alpha waves.

The sleep wave is a wave for inducing the user's sleep and may be output in response to the user's sleep time.

Here, the alpha wave has a frequency band of approximately 8 to 13 kHz (or a frequency band of 7.5 to 14 kHz), and the human brain can be emitted in a comfortable state. The frequency band of the alpha wave can be changed.

The surface wave may overlap at least a portion of the alpha wave.

For example, it is possible for the surface wave to have a frequency band of 6 to 14 kHz which includes all of the alpha wave band. Alternatively, the surface wave may have, for example, a frequency band of 10 to 13 GHz, 6 to 10 GHz or 10 to 15 GHz, which includes a part of the alpha wave band.

As described above, when the surface wave overlaps at least partly with the band of the alpha wave, it can be said that the surface wave includes the alpha wave.

The sleep wave may generate a sleep-inducing effect when it is synchronized with the user's brain waves.

As described above, when the weather wave overlaps at least a part of the band of the beta wave, the weather wave may be said to include a beta wave.

When the weather wave is synchronized with the EEG, an effect of improving concentration is generated, thereby improving a learning ability and cognitive / perception ability, and thereby, an effect of waking the brain from sleep may be generated.

When comparing the surface wave and the weather wave, the frequency band of the surface wave may be lower than the frequency band of the weather wave. Under these conditions, it may be possible to partially overlap surface waves and meteorological waves.

The second driving signal supply unit 611 may supply the driving signal to the auxiliary sound output unit 1A under the control of the control unit 600.

For example, the second driving signal supply unit 611 supplies a third driving signal to the auxiliary sound output unit 1A under the control of the control unit 600 to supply an auxiliary wave including environmental sounds such as water or wind. Can occur.

The sensor unit 630 may generate / save / manage sensing information required for driving the speaker module 10A.

Here, the sensing information may include at least one of a user's breathing information, pulse information, EEG information, and motion information.

To this end, the sensor unit 630 may include a respiratory sensor 631, a pulse sensor 632, an EEG sensor 633, and a motion sensor 634, as shown in FIG.

The breath sensor 631 senses the user's breath and may transmit the sensed information to the controller 600.

The breath sensor 631 may be capable of sensing the user's breath in a state adjacent to the user's mouth or nose.

Alternatively, the breathing center 631 may be capable of sensing the user's breathing based on sound generated when the user breathes. In this case, the respiration sensor 631 may be positioned at a sufficient distance from the user.

The pulse sensor 632 may sense the user's pulse and transmit the sensed information to the controller 600.

The EEG sensor 633 may sense the user's EEG and transmit the sensed information to the controller 600.

The motion sensor 634 may sense the user's motion and transmit the sensed information to the controller 600.

The sensor unit 630 may be provided separately from the PCB disposed on the back plate 40.

For example, the pulse sensor 632 may be implemented in the form of a band worn on the user's wrist. The pulse sensor 632 may transmit pulse information sensed through wired or wireless communication to the control unit 600 through the communication unit 650.

In addition, the sensor unit 630 may be implemented in a separate module form.

The communication unit 650 may perform communication under the control of the control unit 600. For example, when the sensor unit 630 is provided separately from the PCB, the communication unit 650 may communicate with the sensor unit 630.

Alternatively, the communication unit 650 may communicate with other external devices, such as a mobile terminal and / or a server.

The power supply unit 660 may supply power required for driving the speaker module 10A.

The input unit 670 may be a means for inputting a user's command.

The input unit 670 may include a touch input unit such as a touch panel, a key input unit such as a keyboard, and a mouse.

The first embodiment of the sleep induction method using the sleep induction apparatus described above will be described with reference to FIGS. 19 to 25 attached.

19 to 25 are views for explaining a first embodiment of the sleep induction method according to the present invention. Hereinafter, description of the above-described parts may be omitted.

19 and 20, a start time for a user's sleep may be set (S100).

For example, as shown in FIG. 20, the user can set a sleep start time (23:00) and a holding time (10 minutes).

Here, the sleep start time may correspond to information on the start time included in the sleep information.

Thereafter, it is determined whether the start time is reached (S110), and when the start time is determined as a result, the surface wave including the alpha wave may be output (S120). Then, the user can fall asleep more easily and quickly.

The controller 600 may perform such determination. The determination step described below may be considered to be performed by the controller 600 unless otherwise specified.

In this way, it is possible to start outputting the sleep wave at the sleep start time set by the user.

In addition, although not shown, it is possible to output auxiliary waves including environmental sounds (natural sounds) such as water and wind noise together with the surface waves.

Below, unless otherwise specified, the auxiliary wave may be output together with the surface wave.

Thereafter, it is determined whether the holding time has passed (S130), and when the holding time has passed as a result of determination, the output of the surface wave may be terminated (S140).

For example, when the user sets the retention time to 10 minutes, the surface wave may be output for 10 minutes from 23:00, which is the start of sleep, and the output of the surface wave may be ended at 23:10.

In addition, the output of the auxiliary wave can be terminated together with the output of the surface wave.

The holding time can be variously changed.

As described above, when the output of the surface wave is terminated after the holding time, not only power consumption can be reduced, but vibration can be reduced.

In the above, the case of setting the time to start sleep (sleep start time) and controlling the output of the surface wave using the above has been described, but the present invention may not be limited thereto. For example, you can set a target sleep start time and use it. In this regard, referring to the attached FIGS. 21 to 22 are as follows.

Referring to FIG. 21, a user's target sleep start time may be set (S101).

For example, as shown in FIG. 22, the user can set a target sleep start time (23:00) and a holding time (10 minutes).

Here, the target sleep start time may correspond to information on the start time included in the sleep information. In addition, the target sleep start time may be a user's target sleep start time.

Subsequently, it is determined whether the start time of the surface wave output is reached (S111), and when it is determined that the start time is output, the surface wave including the alpha wave may be output (S120).

Here, the surface wave output start time may correspond to the time (22:50) minus the holding time (10 minutes) from the target sleep start time (23:00).

In this way, it is possible to output a sleep wave for a maintenance time before the target correction start time so that the user can sleep at the target sleep start time set by the user.

Thereafter, it is determined whether the target sleep start time is reached (S131), and when the target sleep start time is reached as a result of the determination, the output of the sleep wave may be terminated (S140).

That is, the output of the sleep wave may be ended in response to the target sleep start time set by the user.

On the other hand, it can be seen that the surface wave includes an auxiliary wave.

Referring to FIG. 23, the surface wave may include a main surface wave including alpha waves and an auxiliary wave including environment sounds.

Here, the auxiliary wave is intended to help the user sleep and / or wake up, and may include environmental sounds such as water, waves, and wind.

For example, the speaker module 10A may use the sound of a stream as an environmental sound and output a main surface wave in a frequency band of 8 to 13 GHz. In this case, the user's sleep can be induced more effectively by the combination of the environmental sound and the main surface wave.

The auxiliary wave may serve to inform that the surface wave and / or the weather wave are being output.

For example, when the auxiliary wave includes the sound of the wave, the user can easily check whether the current wave or the weather wave is being output based on the sound of the wave.

On the other hand, it may be possible to end the output of the surface wave by grasping the user's state before reaching the holding time of the surface wave. This will be described with reference to the accompanying FIG. 26.

Referring to FIG. 24, in a state in which the surface wave is output (S120), the sensor unit 630 may sense the user's state information (S150). For example, the sensor unit 630 may sense the user's brain waves, pulse, breathing, motion information, and the like, and transmit it to the controller 600.

Thereafter, the controller 600 may analyze the information sensed by the sensor unit 630 (S151), and determine whether the user has entered the sleep state based on the analysis result (S152).

For example, the control unit 600 may determine that the user has entered the actual sleep state in the case where the user's pulse rate slows below the preset reference frequency, when the user's EEG falls below the preset reference frequency, or the like.

As a result of the determination in step S152, when the user substantially enters the sleep state, the output of the sleep wave may be terminated (S140).

On the other hand, as a result of the determination in step S152, if the user has not actually entered the sleep state, it is determined whether the holding time is terminated (S153), and when the judgment result shows that the holding time is terminated, the output of the sleep wave is output. It can be terminated (S140).

Here, the user information sensed by the sensor unit 630 may be referred to as status information.

As such, in the present invention, it may be possible to determine the termination of the surface wave based on the user's status information.

In consideration of this, the sleep information may include information about the start time (sleep start time, target sleep start time) as well as status information.

On the other hand, the speaker module 10A according to the present invention can output a weather wave on the basis of the information on the weather time. In this regard, referring to the attached FIG. 25, the following will be described.

Referring to FIG. 25, it may be determined whether the preset wake-up time has been reached (S160). For example, when the user sets 07:00 as the wake-up time, the control unit 600 may determine whether the current time has reached 07:00.

As a result of the determination, when the current time reaches the wake-up time, a wake-up wave including a beta wave may be output (S161).

In this case, the user can easily wake up with the help of a weather wave.

In addition, although not shown, it is possible to output auxiliary waves including environmental sounds (natural sounds) such as water and wind noise together with weather waves.

Hereinafter, unless otherwise specified, the auxiliary wave may be output together with the weather wave.

Thereafter, it is determined whether the holding time is reached (S162), and when the holding time is reached as a result of determination, the output of the weather wave may be terminated (S164).

It may be possible to end the output of the auxiliary wave together with the end of the output of the weather wave.

On the other hand, as a result of the determination in step S162, if the maintenance time has not been reached, it is determined whether or not a forced termination command is input (S163), and when a forced termination command is input as a result of the determination, the output of the weather wave is terminated. (S164) Yes.

Here, the forced termination command can be directly input by the user, for example, by pressing a button to end the output of the weather wave.

As described above, when the user outputs a weather wave in response to a preset wake-up time, the user's brain can be promoted to wake up so that the user can be more easily awakened from sleep.

Meanwhile, the sleep inducing device according to the present invention may be able to use a mobile communication terminal such as a smart phone. With regard to this, it will be described below with reference to the accompanying Figures 28 to 37.

The second embodiment of the sleep induction method using the sleep induction device having such a configuration will be described below with reference to the accompanying drawings.

First, the terminal 20A and the speaker module 10A can be matched.

Referring to FIG. 29, the user information of the terminal 20A may be transmitted from the terminal 20A to the server 30A (S200). Here, the device information of the terminal 20A may be transmitted to the server 30A together.

In addition, the device information of the speaker module 10A may be transmitted to the server 30A (S210).

For example, it is possible to transmit the device information of the speaker module 10A from the terminal 20A to the server 30A, or it is possible for the speaker module 10A to directly send the device information to the server 30A. .

As described above, in order to transmit the device information of the speaker module 10A to the server 30A, the terminal 20A and the speaker module 10A need to check each other. For example, the terminal 20A and the speaker module 10A can identify each other using short-range communication such as Bluetooth.

Thereafter, the server 30A may match the user information of the terminal 20A with the device information and the device information of the speaker module 10A (S220), and store information on this, that is, matching information (S230).

As described above, when the terminal 20A and the speaker module 10A are matched with each other, preparation for applying the sleep induction method may be completed.

Referring to FIG. 30, when an app is installed in the terminal 20A, the user may activate the app in a method of executing the app (S300).

Then, the server 30A may check user information and device information (S301), and perform authentication based on this (S302).

For example, suppose that the A terminal and the B speaker module match.

In this case, when the sleep assistant app is activated in the terminal A, and the B speaker module is in a turn-on state, that is, in an activated state, device information and / or user information of the terminal A and the device of the B speaker module Information can be sent to the server 30A.

Then, the server 30A may confirm that the A speaker and the B speaker module matched with the A terminal are in an active state, and perform authentication based on the same.

Thereafter, the control unit 200 of the terminal 20A may determine whether sleep information is set (S303).

Hereinafter, the determination may be performed by the control unit 200 of the terminal 20A, unless otherwise specified.

As a result of the determination in step S303, if sleep information is not set, it may be determined whether to perform another function (S307).

As a result of the determination in step S307, when performing another function, a preset first function (Default 1) may be performed (S312).

On the other hand, as a result of the determination in step S303, when sleep information is set, it may be determined whether information regarding a start time is set (S304).

An example of a method of setting a start time and a hold time in the terminal 20A is posted in FIG. 32.

Here, the information on the start time may correspond to information on the sleep start time or information on the target sleep start time.

When the determination result and the start time information are set in step S304, the terminal 20A determines whether the start time has been reached (S305) and, according to the determination result, outputs first according to the start time information. The control signal may be transmitted to the speaker module 10A (S314).

Then, the speaker module 10A may receive the first output control signal from the terminal 20A and output a surface wave (S306) based on the first output control signal.

On the other hand, if the result of the determination in step S304, information regarding the start time is not set, it may be determined whether the time range is set (S308).

As a result of the determination in step S308, if the time range is not set, a preset second function (Default 2) may be performed (S313).

On the other hand, as a result of the determination in step S308, when the time range is set, it may be determined whether the current time has entered the preset time range (S309).

As a result of the determination in step S309, when the current time enters within a preset time range, the terminal 20A senses the sensor unit 260 and / or the sensor unit 630 included in the speaker module 10A. The received sensing information may be received, and the user's status information may be analyzed based on the received sensing information (S310).

As a result of the analysis, it is determined whether the user is in the sleep ready state (S311), and when the user determines that the user is in the sleep ready state, the first output control signal may be transmitted to the speaker module 10A (S314).

Here, the time range can be said to be a time zone that the user wants to sleep.

This time range may be wider than the holding time.

For example, the user can set a time range when he or she wants to sleep naturally while watching TV.

As described above, when the time range is set, the speaker module 10A may output the surface wave when the state information of the user can easily fall into the sleep.

An example of a method of setting the time range in the terminal 20A is posted in FIG. 33.

For example, as shown in FIG. 33, the target time range for sleep may be set from 23: 00 to 24: 00.

In this case, at least one of the sensor unit 630 of the speaker module 10A and the sensor unit 260 of the terminal 20A receives sensing information that senses the user's pulse, respiration, brain waves, motion, etc. from 23:00. It can be collected / acquired and transferred to the control unit 200 of the terminal 20A.

Then, the controller 200 may generate the user's status information based on the received sensing information and analyze the generated status information.

In the process of collecting and analyzing information of the user's state, when the user's pulse falls below a preset reference number at 23:30, and the EEG is stabilized below a preset reference frequency, the controller 200 of the terminal 20A It can be determined that the user's current state is an easy state to enter the water surface.

Accordingly, the terminal 20A may transmit the first output control signal to the speaker module 10A from 23:00 under the control of the control unit 200, and the speaker module 10A may output a surface wave.

Referring to FIG. 33, in the process of outputting the surface wave, the control unit 200 of the terminal 20A may determine whether a preset retention time has passed (S315). For example, it can be determined whether the output time of the surface wave has passed 10 minutes.

As a result of the determination in step S315, if the retention time has elapsed, the terminal 20A may transmit the first termination control signal to the speaker module 10A (S319).

Then, the speaker module 10A may terminate the output of the surface wave in response to the first termination control signal (S316).

On the other hand, as a result of the determination in step S315, when the retention time has not passed, the control unit 200 of the terminal 20A has its own sensor unit 260 and / or the sensor unit 630 included in the speaker module 10A. The sensing information sensed by the user may be transmitted, and the user's status information may be analyzed based on the received sensing information (S317).

As a result of the analysis, the user determines whether the user is in a sleep state, that is, whether the user has sufficiently entered the sleep (S318), and when the user determines that the user is in the sleep state, transmits a first termination control signal to the speaker module 10A (S319) Can be.

As described above, when the time range is set, since the surface wave can be output only when the user reaches a state in which it is easy to fall into the water, the user can easily sleep, and the power consumption and vibration are generated. Can be reduced.

On the other hand, the sleep inducing apparatus according to the present invention can output a weather wave based on the information about the wake-up time. This will be described with reference to FIGS. 34 and 35 attached.

Referring to FIG. 34, the control unit 200 of the terminal 20A may determine whether the wake-up time is set (S400).

As a result of the determination in step S400, if the wake-up time is not set, it is determined whether there are other preset functions (S403), and the preset third function (Default 3) can be performed according to the judgment result (S404). have.

On the other hand, as a result of the determination in step S400, when the wake-up time is set, it may be determined whether the current time has been set in advance (S401).

As a result of the determination, when the current time has reached the wake-up time, the terminal 20A may transmit the second output control signal to the speaker module 10A (S408).

Then, the speaker module 10A may output a weather wave including a beta wave in response to the second output control signal (S402).

Thereafter, it is determined whether the holding time is reached (S405), and when the holding time is reached as a result of determination, the terminal 20A may transmit the second termination control signal to the speaker module 10A (S409).

Then, the speaker module 10A may terminate the output of the weather wave in response to the second termination control signal (S407).

On the other hand, as a result of the determination in step S405, if the maintenance time has not been reached, it is determined whether or not a forced termination command is input (S406). 2 The termination control signal may be transmitted to the speaker module 10A (S409).

An example of a method for setting the wake-up time in the terminal 20A is posted in FIG. 35.

The terminal 20A may transmit information about the user's sleep to the server 30A, and generate / store / manage / provide statistical information using the server 30A using the information about the user's sleep.
