DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a massage device according to Embodiment 1 of the present invention. In the figure, 1 is a permanent magnet, 2 is a coil, 3 is a diaphragm, 4 is an amplifier, 5 is a mixer, 6 is a signal source A, and 7 is a signal source B. The coil 2 and the diaphragm 3
And an actuator for transmitting the vibration and heat generated in the actuator to the treatment part of the user. Since the diaphragm 3 serves as a part for transmitting vibration and heat, a good heat conductor is used as the material.

Next, the operation will be described. An electric current is applied to the coil 2 of the vibrator by the amplifier 4 to drive the diaphragm 3.
At this time, the oscillation frequency can be arbitrarily set by the signal sources A6 and B7, the respective intensity by the mixer 5, and the overall vibration intensity by the amplifier 4. At that time, heat generated in the coil 2 is given to the affected part through the diaphragm 3 which is a good heat conductor. In addition to massage by vibration, a massage effect by a heat effect is obtained by the heat. Signal source A6 and signal source B7
When periodic vibrations are generated respectively, vibration beats occur when the generated frequencies are different. By vibrating with a beat, an effect equivalent to tapping and massaging can be obtained. By changing the beat in order or chaotically, more effective massage can be performed. Instead of the vibration accompanied by a beat, the intensity of the vibration at a constant frequency may be modulated.

Further, when the modulation of the vibration intensity and the cycle is performed based on the 1 / f fluctuation, a natural feeling of use can be given to the user, which is advantageous for long-time use.

As a signal source B7, a CD player,
If a sound source such as an MD player, a cassette tape player, a record player, a radio, and a television is used, a massage can be performed while listening to music or the like. The music allows you to relax, so you can massage effectively. Also, due to the masking effect of music, vibration sounds other than unpleasant music due to vibration are hard to hear, and massage can be performed comfortably. Vibration caused by music can give a non-constant and complicated pattern of vibration stimulus to the affected area, so that more effective massage can be performed.

Further, a massage effect by the magnetic field generated from the permanent magnet 1 and the coil 2 can be provided.

Embodiment 2 FIG. Next, a second embodiment will be described with reference to the drawings. FIG. 2 is a block diagram showing a configuration of a massage device according to Embodiment 2 of the present invention, and the same or corresponding parts as those in FIG. 1 are denoted by the same reference numerals. FIG. 3 shows a signal pattern used in the massage device according to the second embodiment of the present invention, which is a signal waveform output from the signal source 6. FIG. 3A is a signal pattern that simulates “rubbing” of a massage performed by a human. If the massage is performed intermittently with a signal intensity that is not too large, it will feel lighter and can simulate "rubbing". This signal is a signal obtained by changing the vibration intensity of a triangular function type basic vibration of 120 Hz as shown in the figure. The duration of the signal is 1 second, the vibration intensity is 1/5 of the maximum vibration intensity, and the beginning and end of the signal. Changes the vibration intensity in 1/20 of the duration. This signal is repeated after a pause of one second. In this example, an example using the above values is shown, but the frequency of the basic vibration is 40 Hz to 200 Hz, the vibration intensity is 1/100 to 1/2 of the maximum intensity, the duration is 0.1 second to 10 seconds, and around Changes from 1/50 of the duration to 1
/ 5, the rest period may be a value between 0.1 and 10 seconds.

FIG. 3B is a signal pattern simulating the "massage" of a massage performed by a human. By gradually increasing the signal strength, it is possible to provide an effect as if acupressure was performed. This signal is a triangular function type basic vibration of 120 Hz and is a signal in which the vibration intensity is changed as shown in the figure. The change of the vibration intensity was performed by the following function. f (t) = α · α · ((T−t) / T) · exp [−α · (T−t) / T] / D (1) where t is time (seconds) and α is T is a duration (second), and D is a standardization constant. In this case, α = 7, T = 1, and D is such that the maximum value of this function is the maximum vibration intensity. This signal is repeated after a one second pause. In this example, the example using the above values is shown, but the frequency of the fundamental vibration is 2 from 40 Hz.
00Hz, α may be a value between 2 and 10, and T may be a value between 0.1 and 10.

FIG. 3 (c) is a signal pattern simulating the "hitting" of a massage performed by a human. When a signal having a large signal strength and a low frequency is given for a short time, an effect similar to a hit can be obtained. FIG. 3 (d) shows "striking"
By alternately applying signals to the two actuators placed on the right and left shoulders in another signal pattern, a massage can be performed as if a human were hitting the shoulder. This signal is obtained by changing the vibration intensity of the triangular function type fundamental vibration of 120 Hz as shown in the figure, and the change of the vibration intensity is performed by the following function. g (t) = α · α · (t / T) · exp [−α · t / T] / D (2) The meanings of the parameters are the same as those in equation (1). In this case, α = 55 and T = 1 were used. This signal is repeated after a one second pause. In this example, an example using the above values is shown, but the frequency of the fundamental vibration is changed from 40 Hz to 2 Hz.
00 Hz, α may be a value between 10 and 100, and T may be a value between 0.1 and 10. Further, in this example, a synthesized signal is used, but a similar signal pattern may be created using a musical sound such as a drum or a drum, or a natural sound such as fireworks or lightning.

In the above example, an example is shown in which the stimulus interval is constant during a fixed pause period. However, if the stimulus interval has 1 / f fluctuation, a massage closer to a human massage is performed. be able to.

Incidentally, a massage that simulates a human massage is also realized by a low-frequency massage device. However, in the low-frequency massage, it is necessary to attach a stimulating electrode with jelly to an affected part, and the low frequency massage To exercise. Therefore, there are problems such as the jelly sticking to the affected area and the muscles getting tired, but with the massage device of the present invention, there is no such problem, and it is possible to perform a massage close to a massage performed by a human while wearing clothes. it can.

Further, in the conventional massage device as shown in FIG. 15, since the magnet having a larger load is moved, the massaging device shown in FIG.

Then, it can follow a drastic change, and can perform a more effective massage.

Embodiment 3 FIG. Next, a third embodiment will be described with reference to the drawings. FIG. 4 is a block diagram showing a configuration of a massage device according to Embodiment 3 of the present invention.

Reference numeral 8 denotes a temperature sensor that measures the temperature of the diaphragm 3,
The feedback is made to the amplifier 4.

Next, the operation will be described. The temperature of the diaphragm 3 is measured by the temperature sensor 8, and when the temperature of the diaphragm 3 rises above the set temperature, the vibration intensity given to the diaphragm 3 is adjusted by the amplifier 4 to keep the temperature constant. In order to raise the temperature without changing the vibration intensity, the DC current that does not feel the vibration or the signal intensity at a high frequency may be increased with respect to the intensity of the frequency at which the vibration is felt. Further, if the vibration is performed with a large vibration intensity at the start of use, the temperature of the diaphragm quickly rises, and a thermal effect can be obtained immediately after the start of use. By changing the set temperature with time, a thermal massage in which the temperature changes with time can be performed.

In the figure, the same or corresponding parts as those in FIG. 1 are denoted by the same reference numerals. 9 is a diaphragm covering member.

Next, the operation will be described. Since the diaphragm 3 is made of a material having good heat conductivity, when directly touching an affected part or a hand, the heating effect may be too strong. When covered with the diaphragm covering member 9 made of a material such as cloth or ceramic and applied to the affected part, there is no danger.

If a ceramic that emits far-infrared rays is selected as the diaphragm covering member, a far-infrared heating effect on the body can be obtained.

Embodiment 5 Next, a fifth embodiment will be described with reference to the drawings. FIG. 6 is a block diagram showing a configuration of a main part of a massage device according to Embodiment 5 of the present invention.
The same or corresponding parts as those in FIG. 1 are denoted by the same reference numerals. FIG. 6A shows a configuration in which a part of the diaphragm 3 has a projection. By pressing this projection against the “pot”, the “pot” can be effectively stimulated, and the therapeutic effect can be improved. . FIG. 6B shows that the diaphragm 3 has a gentle projection, and the gentle projection allows the diaphragm 3 to be closely attached to the affected part. A good conductor of heat is used for the projections described above. By doing so, vibration and heat can be effectively transmitted to the treatment portion. The number of protrusions in FIG. 6A does not need to be one, and a plurality of protrusions can be provided corresponding to the position of the “pot”.

Embodiment 6 FIG. Next, a sixth embodiment will be described with reference to the drawings. FIG. 7 is a block diagram showing a configuration of a massage device according to Embodiment 6 of the present invention. In the figure, the same or corresponding parts as those in FIG. 1 are denoted by the same reference numerals. A plurality of actuators (permanent magnet 1, coil 2, diaphragm 3) and a plurality of amplifiers 4 are prepared. Reference numeral 10 denotes a controller for controlling the vibration.

Next, the operation will be described. If a plurality of actuators are installed in the affected part and movements related to each other (for example, movements that sequentially massage toward the heart) are given, massage can be effectively performed on the entire affected part.

Embodiment 7 Next, a seventh embodiment will be described with reference to the drawings. FIG. 8 is a block diagram showing a configuration of a massage device according to Embodiment 7 of the present invention. The same or corresponding parts as those in FIG. 1 are denoted by the same reference numerals. In the present embodiment, an oscillator 11 that generates a pulse signal as a signal source
, And a switching amplifier is used as the amplifier 4. In a switching amplifier, power loss in the amplifier is small, and the weight of the amplifier can be reduced. The switching amplifier controls the current by pulse width modulation.
The pulse width modulation generally has the following modes. One is a simple fixed type anti-phase pulse width modulation, in which the average current is controlled by changing the pulse width of a plus current and a minus current during a fixed modulation period. The other is sine / magnitude pulse width modulation. In the case of a positive current, control is performed by changing the pulse width of the positive current, and no negative current is used. The opposite is true for negative currents. When simple fixed type anti-phase pulse width modulation is used, either positive or negative current always flows to the load and a large amount of current flows to the massage device. Therefore, the temperature rise of the massage device should be increased as compared with the sine / magnitude pulse width modulation. Can be.

The temperature of the massage device can be controlled by combining a simple fixed type antiphase having different modulation efficiencies and a sine / magnitude and controlling the ratio. As shown in FIG. 9, when the set current is equal to or less than a certain value, control is performed by simple fixed type anti-phase pulse width modulation. If it is greater than a certain value, control is performed by sine / magnitude pulse width modulation. For example, in the case of the pulse pattern of the solid line b, the average current is 0 because the pulse width of the plus current and the pulse width of the minus current are the same. In the case of the one-dot chain line c, since the pulse width of the plus current is large, the average current becomes a certain value of plus current. If the set current further increases and cannot be set within the time set for the simple fixed type anti-phase, the dotted line d
As a sine / magnitude pulse width modulation,
The current is controlled by increasing the pulse width of the plus current in the modulation period. If the ratio of the control time controlled by the simple fixed type anti-phase to the control time controlled by the sine magnitude pulse width modulation is feedback-controlled, the temperature of the massage device can be controlled. These pulse width modulation modes are normally modulated so that the DC component becomes zero as a positive / negative symmetric voltage, but a DC component can be generated to further greatly change the balance between vibration and heat generation.
If the square of the current is fed back, control can be performed in proportion to the amount of heat generated. The temperature of the massage device can be controlled by feeding back the measured temperature value.

FIG. 10 is a block diagram showing a configuration of a massage device according to Embodiment 8 of the present invention. In the figure, 12 is a battery and 13 is a cover. Next, the operation will be described. In this embodiment, a battery 12 and an oscillator 11 that generates a pulse signal are used as a signal source, and a switching amplifier is used as the amplifier 4. By doing so, the signal source can be downsized, and the battery can be integrated with the actuator by using a battery as a power source. As a result, the whole can be reduced in size, so that massage can be performed at an arbitrary place such as outdoors.

FIG. 11 is a diagram showing a signal input from the switching amplifier 4 to the coil 2. As shown by the broken line in FIG. 11A, the vibration intensity can be increased by increasing the pulse width. Also, as shown in FIG. 11B, when the interval between the pulses is shortened, the vibration frequency can be increased. If the stimulus intensity and the vibration frequency are controlled only by the pulse width and the time interval of a constant voltage using the amplifier and the oscillator in this way, it is easy to reduce the size of the signal source. Further, since the temperature of the actuator changes depending on the average power of the input signal, the temperature can be controlled by changing the pulse width and the time interval of the constant voltage as described above.

Embodiment 9 Next, a ninth embodiment will be described with reference to the drawings. FIG. 12 is a block diagram showing a configuration of a massage device according to Embodiment 9 of the present invention. In the figure, 14 is a heater.

When the heat generated in the coil 2 alone does not provide enough heat to the affected part, the controller 14 controls the heater 14 using the measurement value of the temperature sensor 8 to apply heat and heat the affected part at an appropriate temperature. Do.

Embodiment 10 FIG. Next, a tenth embodiment will be described with reference to the drawings. FIG. 13 is a block diagram showing a configuration of a massage device according to Embodiment 10 of the present invention. In the figure, reference numeral 15 denotes a force sensor for measuring a pressing force.

Next, the operation will be described. When the massage device is pressed against the affected area with the permanent magnet portion 1 pressed, the vibration of the massage device decreases as the pressing force increases. If the pressing force is measured by the force sensor 15 and the amplifier 4 is controlled by the controller 10 so as to change the vibration according to the pressing force, the control is performed such that the vibration does not change even if the pressing force is increased, or the pressing is performed. As the force is increased, the vibration can be increased.
