Description

Description: TECHNICAL FIELD The present invention relates to a sensation vibrating device that artificially vibrates a bed, a chair, or the like to induce a feeling of tension, a feeling of release, and other feelings by a body sensation. It is a thing.

(Prior Art) A vibrator for removing pain, stiffness, etc. caused by fatigue of each part of the body generally uses a commercial power source as a power source by a motor or an electromagnetic vibrator (such as a solenoid). It gives vibration and sets the strength to a constant level.

By the way, in recent years, the connection between music and medicine has been drawing attention, and various research presentations have begun. This is called bio music, for example, 19
There is the Japan Bio Music Study Group, which was established in 1986 with the chairman, Mr. Shigeaki Hinohara, President of St. Luke's College of Nursing, and the results of the connection between music and medicine have been announced. This has been published in the literature. One example is the first report on music therapy, published in the Japanese Society of Psychosomatic Medicine Vol. 26, "Abstracts of Psychosomatic Medicine". In addition to Mr. Shigeaki Hinohara, Katsutaro Nagata, Department of Anesthesiology, Toho University Ohashi Hospital. "Effects of sensational acoustic system on treatment of unstable hypertension" announced by Dr. Ranko Katayama and others of Life Planning Center
There is.

Unlike the vibrator described above, the vibrating device proposed by the applicant of the present invention uses a low-pitched part of a music signal as a vibration source, and while listening to music, it is possible to experience a vibration that matches the vibrating part to enhance the presence of the music. Besides, it can be used as relaxation for the body and mind.

As the vibration unit used in the sensible vibration device, a vibration unit having a relatively good frequency response characteristic and transient response characteristic as shown in Japanese Patent Publication No. 58-9640 is used. This is a principle similar to that of a speaker that emits sound, that is, a magnet and a coil that receives a low-frequency current cause a magnetic interference action to generate vibration in accordance with the frequency of the energized current. This is, for example,
0692, or the arrangement as in Japanese Utility Model Application No. 61-098695, and a human body placing object such as a chair or a bed (including a floor board or the like depending on the case).
It is attached at a position corresponding to the part where the user feels comfort.

In this way, if a low-pitched signal of music is applied to the vibration unit attached to the human body placement object, the low-pitched portion of the musical sound is output as vibration. Then, the user senses the sound being heard from the ear and the vibration in the low frequency range, thereby synergistically obtaining a pleasant sensation.

(Problems to be Solved by the Invention) As described above, the connection between music and medical care has received a great deal of attention academically, and it can be seen that the sensible vibration device exerts an excitement and stabilization action on the user. Listening to known music makes me nervous about what will happen next and makes me nervous. What kind of device is actually used for treatment is an unexplored stage. For example, no effect could be expected for disorders in the neuropsychiatric field such as psychosomatic disorders, neuroses, and senile dementia.

It is an object of the present invention to provide a sensitive vibration device that causes another sense that cannot be obtained from the bodily vibration device.

(Means for Solving the Problems) As a means for achieving the above object, the present invention corresponds to a structure of the sensitive vibration device for a portion of a human body placing object such as a chair or a bed where the body feels comfortable. At the position, a vibration unit that receives a low-frequency current in the low frequency range of music or the like to generate mechanical vibration is attached, and the vibration unit is made to repeatedly attenuate and increase the low-frequency current with time, and to repeat it. It is characterized in that it is connected to the output end of a circuit which alternately outputs low frequency currents of different frequencies which are approximated in synchronization with the operation.

(Operation) In the present invention, a vibration signal is changed to a music signal without electrical repetition, a vibrating unit is activated by different low-frequency currents having a frequency of several seconds or more, and frequencies that are alternately approximated,
It is intended to allow a user sitting or lying on this human body placing object to experience.

The vibration of the vibration unit is a low frequency that alternates regularly,
It is an artificial thing that changes with regular and slower intensity, and can repeatedly stimulate the sensitivity under the same conditions. For example, when a strong vibration is damped, it causes the image of a bell belling, and what feels like the vibration intensity is undulating can gradually give rise to the image that the waves gradually get bigger and then go away. .

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings. First, FIG. 1 is a block diagram of an example of a circuit for generating a sensitive vibration signal, and 1 is a voltage controlled oscillator (hereinafter, referred to as VCO
2) is a voltage control amplifier (hereinafter referred to as VCA). The output signal of VCO1 is amplified by VCA2 and supplied to a vibration unit (not shown). Reference numeral 3 is a frequency control oscillator (hereinafter referred to as FCO), and 4 is an envelope oscillator (hereinafter referred to as ENV).

Each of these circuits are connected as shown and operate as follows.

As one of them, as shown in FIG. 2, ENV4 oscillates a triangular wave having a cycle of about 12 seconds (about 0.08 Hz). FC this
It is input to O3 and oscillates a synchronized rectangular wave. On the other hand, VC
O1 is set so as to oscillate at 47 Hz and 35 Hz, and oscillates alternately according to the output of FCO3.

Therefore, signals of 47 Hz and 35 Hz are alternately input to the VCA2, and a triangular wave is input from another terminal. VCA
The output of 2 has a triangular wave envelope as shown in the figure,
The output signal oscillates at 47 Hz when rising and at 35 Hz when falling (other combinations are possible depending on the timing).
This output is power-amplified by a power amplifier (not shown) to activate the vibration unit.

The operation of the vibration unit vibrates at a slightly higher frequency of 47 Hz, and the vibration gradually increases, and after a predetermined time, it switches to a slightly lower frequency of 35 Hz, and the vibration gradually decreases, and the vibration gradually decreases for a predetermined time. After that, it switches to 47 Hz.

Therefore, unlike conventional irrelevant relaxation, which is obtained from the vibration of music that changes its frequency and its strength one after another, its strength and weakness can be easily extracted from human memory by artificial vibration. . And, for example, in the image of the perceptual vibration signal, for example, in the case where the vibration intensity is gently repeated, a feeling that waves are rushing to the beach and eventually leaving is obtained. And since this is repeated in a very slow cycle, it works to calm the mind of the user.

The oscillating frequencies of 47 Hz and 35 Hz are selected because the frequencies around this have a very pleasant experimental effect. 47Hz and 35Hz are perfect 4 in music.
Since it is a pitch interval, "pleasure" is also in this sense
Is easy to make. However, this frequency does not have to be this, but it is merely an example, and another frequency may be used. The same applies to the cycle of about 12 seconds. It is convenient if these can be changed appropriately.

Next, as a sensitive vibration signal of another image, as shown in FIG. 3, a sawtooth wave having a period of about 7 seconds (about 0.14 Hz) is oscillated by ENV4. This is input to the FCO 3 for synchronization, and a rectangular wave having a frequency of 1/2 is oscillated. on the other hand,
The VCO 1 is set to oscillate at 47 Hz and 35 Hz, and alternately oscillates according to the output of the FCO 3.

That is, signals of 47 Hz and 35 Hz are alternately input to the vibration unit, and moreover, due to the sawtooth wave envelope,
It vibrates greatly when the signal is switched, and gradually oscillates gradually with the passage of time. Repeatedly experiencing this, the damping vibration of strong sound becomes an element of the image, giving the image that the bell of high sound (47 Hz) and the bell of low sound (35 Hz) slowly alternate.

Although a simple waveform is prepared for VCO1 and ENV4, it is also possible to create a high-pitched sound in consideration of music and harmony and add it to add an auditory effect.

The signals shown in FIGS. 2 and 3 can be realized by a simple circuit. FIG. 4 and FIG. 5 show examples thereof. FIG. 4 shows an example of the circuit for producing the signal shown in FIG. 2, which is a well-known free-running multivibrator using an operational amplifier 5 in which a triangular wave and a rectangular wave are simultaneously produced by one circuit. Therefore, if this circuit is used, EN
V4 and FCO3 can be realized simultaneously. Further, the VCO 1 combined with this circuit also only switches two frequencies with a rectangular wave, so that a resistor or a capacitor which is an oscillating element of the oscillating circuit is simply turned on and off by an analog switch such as an FET (field effect transistor). Very simple ones are not necessary, and complicated and high performance ones used in music synthesizers are not necessarily required. The same applies to VCA2.

FIG. 5 shows an example of a circuit for obtaining the signals shown in FIG. In this circuit, the negative feedback resistor of the free-running multivibrator by the operational amplifier 5 is short-circuited with a diode to shorten the rise time, and the rectangular wave divided by 1/2 by the frequency divider circuit by the flip-flop circuit 6 is generated. Get E
The output of NV4 and the output of FCO3 are obtained.
Others are the same as those in FIG. The one shown in FIG. 6 is provided with a large number of FCOs 3 and ENVs 4 to generate various patterns of sensitive vibration signals, and these are used as changeover switches
It can be selected with. In this circuit, in order to obtain a higher effect, the period can be adjusted (speed adjustment) by the variable resistor 9. In the figure, reference numeral 10 is a variable resistor for intensity adjustment, 11 is a power amplifier, and 12 is a vibration unit.

In FIG. 7, the sensation vibration system 14 and the sensation vibration device 14 which have been conventionally developed are combined, and the changeover switch 15 is used for switching so that a wider change, application and effect can be obtained. It was done. In this figure, 16 and 17 are amplifiers for amplifying left and right channel audio signals, and 18 and 19 are speakers (or headphones).

For the convenience of description, the above description is based on an analog circuit, but it goes without saying that a digital method may be used. For example, the waveform information may be stored in a memory circuit and read by a voice synthesis technique, or by a microcomputer. Further, it is possible to use a personal computer so that various kinds of sensitive vibration signals can be programmed. It is possible to give various patterns in a certain order, to make the mind calm down and to increase the effect of falling asleep by making the cycle gradually slower with the passage of time in the early cycle.

(Effects of the Invention) Since the present invention is configured as described above,
By artificially setting the low-frequency frequency that causes the sensible vibration, and by artificially repeatedly changing the signal strength and weakness, the vibration with the regularity set in this way is transmitted to the part where the user's body can easily experience it. Then, repeatedly feel the vibration.
As a result, the user can enter the world of the image by stimulating the sense and easily pulling out the image. By using this, a great effect can be obtained for medical purposes, particularly mental stability and relaxation.
