[First Embodiment]
FIG. 1 shows a chair type massage machine equipped with a striking force generator.
As shown in FIG. 1, the chair type massage machine 1 is provided in a seat part 2, a reclining backrest part 3 provided on the back side of the seat part 2, and the seat part 2 and the backrest part 3. A striking force generator 4 is provided.

  The seat 2 is supported by the legs 5 and set to a predetermined height. Armrests 6 are provided on the left and right sides of the seat portion 2. Inside the backrest 3, a backrest massage mechanism 8 that can be massaged or struck by swinging the treatment element 7 is incorporated so as to be movable up and down. The range from the waist to the neck of the human body sitting on the seat 2 can be massaged by swinging the child 7.

  The chair type massage machine 1 of the first embodiment is also provided with a lower limb massage machine 10 for massaging the lower limbs. Specifically, a pair of left and right support members 11 swingable in the front-rear direction are provided on the left and right sides of the front portion of the seat portion 2, and a lower limb massage machine 10 is swingably attached to the support member 11. Yes. This lower limb massage machine 10 is a lower limb massage mechanism (not shown) that massages the lower limbs by swinging a pair of left and right lower limb massage members 12, 12 that are spaced apart from each other so as to sandwich the lower limbs. Is provided. By swinging the lower limb massage members 12, 12 by the lower limb massage mechanism, the range from the foot of the human body sitting on the seat 2 to the inflated shin can be massaged.

In addition, the chair type massage machine 1 is provided with a striking force generating means 15 for performing a tapping massage treatment by repeatedly applying a striking force to the affected part, in addition to the treatment element 7 of the backrest massage mechanism 8. . A plurality of striking force generating means 15 may be arranged in the left-right direction inside the backrest 3, or a plurality of hitting force generating means 15 may be arranged inside the seat 2.
The striking force generating means 15 is different in structure from the backrest massage mechanism 8 and the lower limb massage mechanism as will be described later, and applies striking force to the affected part by linear reciprocating motion. The striking strength, striking cycle, etc. of the striking force generating means 15 are controlled by a drive signal from the control means 16 connected to the striking force generating means 15. The striking force generator 15 and the controller 16 constitute a striking force generator 4.

  As shown in FIGS. 2 (a) and 2 (b), the striking force generating means 15 applies striking force to the affected area by moving the drive piston 17 in the axial direction. A wound excitation coil 18 (solenoid), a drive piston 17 inserted into the excitation coil 18, and a case 19 in which the excitation coil 18 and the drive piston 17 are placed are provided.

  Specifically, the exciting coil 18 is formed by winding a conducting wire, and has a hollow portion 20 at the center, to which a drive signal from the control means 16 is applied. A drive piston 17 is inserted into the hollow portion 20 of the exciting coil 18. The axial direction of the hollow portion 20 and the axial direction of the drive piston 17 face the same direction, and the drive piston 17 is inserted coaxially with the hollow portion 20. The drive piston 17 is configured such that a rod-shaped iron core, which is a magnetic material, and a non-magnetic synthetic resin rod are connected in the axial direction.

Inside the case 19 is housed an excitation coil 18 and a drive piston 17 inserted into the excitation coil 18. At least one side of the case 19 is provided with an entrance / exit 21 through which the front end side of the drive piston 17 enters and exits. For convenience of explanation, the entrance / exit 21 side where the distal end side 17a of the drive piston 17 enters / exits is referred to as a striking action side.
On the striking action side of the case 19, a belt-like elastically deformable spring material 22 is provided so as to close the entrance / exit 21 of the case 19. In each case 19, the side on which the spring material 22 is provided (the striking action side) is directed to the surface of the backrest 3 (the side for performing massage) or the surface of the seat 2 (the side for performing massage). Yes.

As shown in FIG. 2A, in a state where the control means 16 does not output a drive signal (current) to the exciting coil 18, the drive piston 17 is pushed back toward the case 19 by the spring material 22, so that the drive piston 17 The distal end portion 17a is located in the case 19 and does not exit from the entrance / exit 21.
As shown in FIG. 2B, when the control means 16 outputs a drive signal to the excitation coil 18, an electromagnetic force is generated in the excitation coil 18, and the drive piston 17 becomes a pushing back force of the spring material 22 by this electromagnetic force. On the contrary, it moves in the direction of jumping out of the case 19 and exits from the entrance 21 of the case 19. In a state where the drive signal is continuously output to the excitation coil 18, the drive piston 17 remains protruding from the entrance / exit 21. When the output of the drive signal to the excitation coil 18 is stopped, the force acting on the drive piston 17 is only the pushing back force of the spring material 22, and the drive piston 17 moves in the direction of retreating into the excitation coil 18.

  That is, when current is supplied to the exciting coil 18, a part of the driving piston 17 protrudes from the hollow portion 20 of the exciting coil 18, and when the current is interrupted, the driving piston 17 is elastic of the belt-shaped spring material 22. The force returns to the hollow portion 20 in the center of the exciting coil 18. By repeating this, the drive piston 17 repeatedly moves back and forth, and it becomes possible to apply a hitting massage (tapping massage) to the affected part.

  The spring material 22 provided in the striking force generating means 15 is not an essential member. Even with the striking force generating means 15 that does not have the spring material 22, by applying an alternating drive signal, the driving piston 17 can move out and retract to perform a comfortable striking massage. . Even when a pulse-type drive signal that alternately outputs the positive side and 0 is applied, the drive piston 17 is retracted by the reaction force of the output operation, so that the drive piston 17 is reliably output. It will be a retreat action.

On the other hand, the control means 16 outputs a drive signal (current) linked to music to the exciting coil 18, and is built in, for example, a chair type massage apparatus.
The control means 16 has a music data storage unit 25 in which music data is stored in advance. The music data storage unit 25 stores various music data, and a music type (genre), a music name, a music artist name, and the like can be appropriately selected from the music data by a remote controller or the like. Yes. Here, the music includes not only those produced artificially but also those recorded with natural sounds such as wind, waves and animal calls.

The control means 16 outputs a drive signal based on the audio signal based on the music data selected from the music data storage unit 25. For example, a drive signal that is linked to the amplitude or frequency of the audio signal may be output, or a drive signal that is linked only to a signal of a specific frequency from the audio signal may be output.
Further, the control means 16 may output a drive signal when there is a signal having a predetermined strength or higher (amplitude is equal to or higher than a predetermined value) in the audio signal.

FIG. 7 shows an example in which a drive signal is output based on the strength (level) of music.
When a drive signal is output in accordance with the strength of music, as shown in FIG. 7A, the control means 16 first reads an audio signal from the music data storage unit 25, as shown in FIG. 7B. Smoothly connect each peak of the loaded audio signal. This processing may be performed by a peak detection circuit constituted by a half-wave rectification smoothing circuit or the like.

Next, as shown in FIG. 7 (c), the control means 16 cuts out a portion equal to or greater than the threshold value L in the waveform having the connected peaks, and a trigger signal that triggers the base point of the cut-out waveform (FIG. 7 (c)). Are extracted A, A ′). Note that the threshold L may be a fixed value or a value obtained by averaging the amplitudes of the audio signals.
Thereafter, as shown in FIG. 7D, the control means 16 outputs a pulse waveform having a predetermined width (for example, 3 msec), with the time when the trigger signal is extracted as the rising edge (output start point) of the drive signal. To do. This pulse waveform is input to the striking force generating means 15, and the striking force generating means 15 is driven in accordance with the music.

  7A to 7D may be realized by using a hardware circuit, but may be performed by software processing. That is, an external audio signal (music) is A / D converted and stored as digital data in the music data storage unit 25, and the digital data extracted from the music data storage unit 25 is subjected to peak detection and a threshold value or more. It is preferable to perform processing such as clipping of the waveform on the software.

Furthermore, the control means 16 may extract a beat component (time signature, rhythm, for example, a sound emitted from a drum part or a bass part) from the audio signal and output a drive signal corresponding to the beat component. . That is, a drive signal obtained based on the beat component of music may be output.
In addition to the above method, a programmer or the like may create a drive signal output pattern linked to music in advance.

  If a drive signal linked to music is applied to the excitation coil 18 by such control means 16, for example, the speed of the drive piston 17 can be freely moved and the degree of protrusion of the drive piston 17 can be freely selected according to the strength of music (sound). It is possible to change the distance between the drive pistons 17 according to the rhythm of the music, and the massage treatment in synchronization with the music can be performed.

  Moreover, since the speed of the impact massage by the impact force generating means 15 (the reaction speed of the movement of the drive piston 17) is very fast, the impact force generating means 15 is driven in conjunction with the music without delay. Can do. Therefore, as in the prior art, there is no time lag between music and massage treatment (massage by the massage mechanism), and the massage treatment can be reliably performed according to the music.

A music playback unit 26 for playing back music is connected to the control means 16 and plays back the selected music data. Thereby, the user can perform a massage by the striking force generating means 15 while listening to music.
In the above description, the music data is stored in the music data storage unit 25 in advance in the control means 16, but instead of this, the control means 16 is input to accept a recording medium (such as a CD) containing the music data. A drive signal may be output according to music data (for example, WAVE data or MP3 data) in a recording medium prepared by the user.

Further, when the striking force generating device 4 has a plurality of striking force generating means 15, the driving signal to be output according to the audio signal may be changed by each striking force generating means 15.
For example, by applying FFT to the audio signal, the striking force generating means 15 that outputs a drive signal for each frequency component may be appropriately divided into a high frequency component, a medium frequency component, a low frequency component, and the like. At this time, when a high frequency component or a medium frequency component of the audio signal is output during music reproduction, a driving signal is output to the striking force generating means 15 disposed in the backrest 3 and the low frequency component of the audio signal is output. Is output, the location of the striking force generating means 15 that outputs the driving signal for each frequency may be changed, such as outputting a driving signal to the striking force generating means 15 disposed on the seat 2. By doing so, the affected area to be massaged can be changed according to the music.

  Furthermore, it is preferable that the massage operation in the backrest massage mechanism 8 and the massage mechanism for the lower limbs and the massage operation by the striking force generator 4 are independent and non-interlocked, but all the massage mechanisms are interlocked, You may make it operate | move according to music data. In other words, the operations of the backrest massage mechanism 8 and the lower limb massage mechanism may be linked to the music data or not.

In addition, LED lighting having various colors is installed around the chair type massage machine 1, and the illumination intensity of the LED lighting is output from the control unit “drive obtained based on music data” You may make it control based on a "signal."

[Fourth Embodiment]
In the control means 16 of 1st Embodiment, after performing the signal processing shown in FIG. 7, the drive signal was produced | generated, and the striking force generation means 15 of the chair type massage machine 1 was driven with the obtained drive signal. .

In the fourth embodiment, a “method for generating a driving signal of the striking force generating means 15”, which is different from the signal processing method disclosed in the first embodiment, will be described.
As shown in FIG. 8, the control means 16 includes an amplifier unit 60 that amplifies a music signal (audio signal), and a filter unit 61 that extracts a low frequency sound region and a high frequency sound region from the audio signal amplified by the amplifier unit 60. A trigger signal generation unit 62 that generates a trigger signal based on the output of the filter unit 61; a drive signal generation unit 63 that generates a drive signal that moves the striking force generation means 15 based on the generated trigger signal; ,have.

Specifically, the amplifier unit 60 amplifies an externally input audio signal, and an existing audio amplifier IC or the like can be employed.
The audio signal (FIG. 8A) amplified by the amplifier unit 60 is introduced into the filter unit 61. The filter unit 61 includes a low-pass filter 64 that extracts a low-frequency sound range emitted by a drum or the like, and a high-pass filter 65 that extracts a high-frequency sound range emitted by an electric guitar or the like. By passing through the filter unit 61, an audio signal from which an intermediate frequency range, that is, a vocal (human voice) is excluded is extracted. In this way, by eliminating the vocal sound range, it is possible to avoid unnecessarily driving the striking force generator 4 and perform a striking massage that is steadily linked to music.

  In addition, as shown in FIG. 9, it is also possible to provide the filter unit 61 with a bandpass filter 69 that passes the intermediate frequency sound range. By doing so, a music signal (a music signal excluding an extremely low frequency range or a high frequency range) that excludes a predetermined frequency range from the input music signal is extracted. It is possible to realize a batting massage that is not performed. In FIG. 9, the configuration requirements other than the bandpass filter 69 are the same as those in FIG.

The signal output from the filter unit 61 is introduced into a trigger signal generation unit 62 having a differentiation unit 66, an integration unit 67, and a comparator 68.
Specifically, the signal from the filter unit 61 is introduced into the differentiating unit 66, and a portion where the music fluctuates is extracted as a peak signal (differential waveform). At the same time, the signal from the filter unit 61 is introduced into the integrating unit 67, and a value corresponding to the integrated value, that is, the average value of the signal is obtained. This is adopted as the threshold value L.

The peak signal output from the differentiating unit 66 and the threshold value L obtained by the integrating unit 67 are respectively input to a comparator 68 (comparator), and a portion of the peak signal that is equal to or greater than the threshold value L is cut out. A trigger signal (symbols A and A ′ in FIG. 8B) with the base point as a trigger is output.
Since the integration unit 67 calculates the threshold value L by averaging the amplitudes of the input audio signals, it can always calculate an appropriate threshold value L even if the intensity (magnitude) of the audio signal varies. It has become.

  Thereafter, the output from the comparator 68, that is, the trigger signal generation unit 62 is input to the drive signal generation unit 63, and when the trigger signal is extracted (A, A ′) as indicated by the hatched area in FIG. ) Is output as a drive signal (drive AC output) output start point, and a drive AC having a predetermined time width is output. The time width to be output may be determined according to the desired strength of the striking force generating means 15, and for example, 3 to 4 msec is adopted.

  In FIG. 8C, the output of the drive signal to the exciting coil 18 is the time when the trigger signal is extracted regardless of the polarity of the drive AC output. By doing in this way, the striking force generation means 15 will operate | move reliably without a delay with respect to music. However, the drive signal output to the excitation coil 18 may be started when the trigger signal is extracted only in the + polarity (or-polarity) of the drive AC output.

The driving signal (driving AC output) generated as described above is input to the striking force generating means 15, and the striking force generating means 15 is driven in accordance with the music.
The processing of the fourth embodiment described above may be realized using a hardware circuit, but may be performed by software processing.
In addition, this invention is not limited to said each embodiment, The shape, structure, material, combination, etc. of each member can be suitably changed in the range which does not change the essence of invention.
