DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a pine surge device that generates vibrations in synchronization with music audio signals.

(Prior art) Generally, pine surge devices promote blood circulation by applying vibration to various parts of the user's body.
It is well known that it helps in recovering from muscle fatigue. In this case, the pine surge effect can be enhanced by not only providing vibrations to the user, but also providing psychologically pleasant vibrations to the user.

As such a pine surge device, the special public
There is a prior art disclosed in Publication No. 24839. This prior art attempts to generate rhythmic vibrations by causing an electromagnetic vibration device to operate intermittently depending on the intensity of music or voice. However, such electromagnetic vibration devices generally attempt to generate a certain vibration in reciprocating motion through magnetic interference between a coil through which current flows and a magnet. Therefore,
In order to obtain strong vibrations, it is necessary to increase the size of the electromagnetic vibration device or to use a large number of electromagnetic vibration devices.

Therefore, the applicant proposed a pine surge device disclosed in Japanese Patent Application No. 59-209469. This pine surge device generates vibrations by driving a motor having an eccentrically rotating weight in synchronization with a music audio signal. With such a device, stronger vibration can be obtained than with an electromagnetic vibration device, and the pine surge effect can be improved.

However, when the weight is eccentrically rotated by a motor, the following speed of the motor may be slightly delayed relative to the music audio signal, and it may not be possible to obtain rhythmic vibrations that are completely synchronized with the rhythm of the music audio. It was hot.

(Problems to be Solved by the Invention) This invention was made based on the above circumstances, and its purpose is to obtain rhythmic vibrations that are completely synchronized with musical audio signals. On the other hand, it is an object of the present invention to provide a pine surge device in which a strong vibration having a pine surge effect can be obtained by eccentric rotation of a weight, and the strong rhythmic vibration can provide a feeling close to electromagnetic vibration.

[Structure of the invention]

(Means and effects for solving the problems) In order to solve the above problems, the present invention includes a device main body and a first vibration generator that is provided in the device main body and generates electromagnetic vibration in synchronization with a music audio signal. and a pair of weights that are installed inside the device main body and are attached eccentrically and out of phase to the two-axis motor, and the motor vibrates mechanically when the motor is driven in synchronization with the music audio signal. 2 vibration generators. The first vibration generator can generate rhythmic vibrations that are completely synchronized with the musical audio signal, and the second vibration generator can also generate strong vibrations that are synchronized with the rhythm of the musical audio. did.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG. 1 shows a chair-type pine surgery device, which is equipped with a seat portion 1. FIG. Armrests 2 (only one of which is shown) that support the seat 1 are attached to both widthwise ends of the seat 1. Further, a back portion 3 is connected to the rear end of the seat portion 1 so as to be rotatable and holdable at any angle.
The seat part 1 has a seat frame 4 and a seat frame 4.
It is formed from a cushion 5 provided above.

Further, the back portion 3 has a back frame 6, and a bump-full plate 7 is attached to the open front surface of the back frame 6 with a screw 9 via a vibration isolating rubber 8 in a manner that prevents vibration. This baffle plate 7 has an opening 11 formed therein, and on the back side of the buffle plate 7 facing this opening 11 is a first hole that generates electromagnetic vibration.
A bass speaker 12 as a vibration generator is attached. Further, an elastic plate 15 is attached to the front surface of the buff-full plate 7 via a support member 14 having a large number of small holes 13 formed therein. This elastic plate 15 is a semi-rigid material having elasticity that does not absorb vibrations significantly, and is made of a semi-hard material having an elasticity that does not greatly absorb vibrations.
A large number of through holes 16 are bored in the portion corresponding to 1. Further, a motor vibrator 17 as a second vibration generator is embedded in the elastic plate 15 at the bottom in the vertical direction. This motor vibrator 17 has a cylindrical cover 18 as shown in FIGS. 2 and 3. A two-shaft motor 19 is housed and held within this cover 18, and weights 21a and 21b are attached to both ends of a shaft 21 of this two-shaft motor 19, respectively. In other words, these weights 21a and 21b are attached eccentrically to the shaft 21, and one weight 21a and the other weight 21b are attached with a phase shift of 180 degrees with respect to the rotation direction. . Therefore, when the shaft 21 rotates, the phase of the pair of weights 21a and 21b is more than when they are attached without shifting their phases.
The vibration of the motor 19 delicately responds to the music audio signal to achieve fine tuning, and contributes to speeding up the start of tuning. That is, the waveform A when the pair of weights 21a and 21b are attached and rotated without shifting the phase,
Waveform B when mounted and rotated with a 180 degree phase shift appears as shown in FIG.

In addition, the deflection indicated by the angle a at both longitudinal ends of the cover 18 can be made sufficiently larger than when the phases of the weights 21a and 21b are the same, and by swinging at the angle a, the cover 18 leans against the back 3. The user can receive a strong pine surge on pressure points located on both sides of the user's spine. Furthermore, flanges 2 are provided at both longitudinal ends of the cover 18, respectively.
2 are provided, and one end of a transmission member 23 having a U-shaped cross section is fixed to these flanges 22 with screws. Since the transmission member 23 protrudes outward in the axial direction from the end surface of the cover 18 by the length A, the deflection of the other end of the transmission member 23 is magnified compared to the deflection angle a of the cover 18. become. Note that the motor vibrator 17 is connected to its transmission member 23.
It is buried in the elastic plate 15 with the other end facing the front side of the elastic plate 15.

Furthermore, a speaker 24 for medium and high frequency sounds is provided on the upper part of the upper back part 3, and a cassette deck 25 is further provided on the armrest body 2. Also, the back 3
is covered by an exterior body 26 shown in chain lines in FIG.

On the other hand, the bass speaker 12, the motor vibrator 17, the medium/high frequency speaker 24, and the cassette deck 25 are connected by wiring as shown in FIG. In other words, the DC power supply 31 is connected to the cassette deck 2.
5 is connected, and bass speaker 1 is connected.
2. Motor vibrator 17 and mid-high sound speaker 2
4 are the first to third amplifier circuits 32a...3, respectively.
2c. The music audio signals output from the cassette deck 25 are input to first to third attenuators 33a...33c, respectively. Of the music audio signal input to the first attenuator 33a, only the component below 110Hz is the first attenuator 33a.
The signal passes through a low-pass filter 34 and is amplified by a first amplifier 32a to drive the motor vibrator 17. In addition, the second attenuator 33
The music audio signal input to b is sent to the second attenuator 32b.
After the signal is amplified, the signal is input to the medium and high frequency speaker 24. Further, the music audio signal inputted to the third attenuator 33c is amplified by the third amplifier 32c via a second low-pass filter 35 that passes only the low-frequency component of 60 Hz drop, and then is amplified by the third amplifier 32c. The signal is input to the speaker 12 and activated.

Note that the cassette deck 25 and each attenuator 33
An external input terminal is connected between the attenuators 33a...33c through a switch 36, so that music audio signals can be input from sources other than the cassette deck 25 to each of the attenuators 33a...33c.

According to the pine surge device configured in this manner, when the user is seated on the seat 1 and leans back 3 and turns on the cassette deck 25 to output a music audio signal, one of the signals is The motor vibrator 17 is driven by the component of 110Hz or less,
The bass speaker 12 is driven by components of 60 Hz or less. Then, the elastic plate 15 vibrates due to the relatively strong vibrations generated by the motor vibrator 17, and the user who is leaning against the back 3 is stimulated by the vibration, and the bass speaker 12
The electromagnetic vibrations of the device are converted into sound pressure and the user is stimulated with vibrations synchronized with the music audio signal. In other words,
The user receives weak vibrations from the bass speaker 12,
The user can receive pine surge by both the strong vibration from the motor vibrator 17, and since the pine surge is not a simple continuous vibration but a rhythmic vibration, the user can receive extremely comfortable and highly effective pine surge. can.

Further, the motor vibrator 17 is connected to its two-axis motor 19.
Since the phases of the pair of weights 21a and 21b attached to the 21a and 21b are shifted by 180 degrees, the rotation of the two-axis motor 19 smoothly follows changes in the music audio signal, that is, it vibrates in synchronization with the rhythm of the music audio signal. Therefore, this also results in a comfortable pine surge. Furthermore, the motor vibrator 17 has its cover 1
By attaching the transmission member 23 to the cover 8, the amplitude generated in the cover 18 in the direction orthogonal to the axial direction is expanded, thereby making it possible to intensify the vibration of the motor vibrator 17.

In addition, a motor vibrator 17 and a bass speaker 12
The strength of the vibration is determined by the dampers 33a and 33c, respectively.
For example, it is also possible to vibrate only one of them. Therefore, users can combine strong vibrations with a pine surge effect and rhythmic vibrations that are perfectly synchronized with music audio signals in various conditions according to their preferences, so they can create the vibrations that are best suited to them. You can receive Pine Surge at
