Description

[Detailed Description of the Invention] <Field of Application of the Invention> This invention relates to a vibrating body that utilizes electromagnetic force, and more specifically, it stimulates a living body with vibration to promote metabolism and alleviate pain. -Relates to a vibrating body for relieving symptoms and regulating sleep.

<Conventional technology> Conventionally, vibrating bodies that stimulate living organisms to promote their metabolism and reduce and eliminate various types of pain have been used.
Two or three methods were known.

A typical example is to attach an eccentric weight to the rotating shaft of an electric motor, and place a diaphragm appropriately near the eccentric weight. When the electric motor is energized, the eccentric weight intermittently vibrates the diaphragm. There are also types that generate vibrations by striking. Although this method has the advantage of being able to be constructed with a relatively small number of parts and easily generating strong vibrations, in principle the entire device tends to be bulky, and when used for a long time,
However, there is a drawback that the operating noise of the electric motor and the impact noise caused by the eccentric weight tend to become louder. These shortcomings are not very serious when limited to the purpose of reducing or eliminating pain, but they can become serious when the main purpose is sleep regulation or depending on the environment in which they are used. However, there were limits to its use.

Other methods, such as those disclosed in Japanese Utility Model Application Publications No. 50-26684 and No. 53-41892, are such that a ferromagnetic diaphragm is placed near the solenoid, and the solenoid has an alternating frequency. The electromagnetic force generated by applying an electric current periodically attracts the diaphragm to generate vibrations. Compared to the former method, this method allows the vibrating body to be made smaller and the operating noise can be kept to a relatively low level, but since a solenoid is used, there is a limit to reducing its thickness. In addition, it had the disadvantage that the solenoid generated significant heat when used for a long period of time.

<Problems to be Solved by the Invention> The present invention is intended to eliminate these drawbacks of the prior art, and aims to provide a compact and lightweight device that has good heat dissipation, reduces operating noise, and can be used for a long period of time. It is an object of the present invention to provide an electromagnetic vibrator whose performance is unlikely to deteriorate.

<Means for Solving the Problems> As a result of intensive research by the present inventors, it has been found that an electromagnetic vibrating body having a flat and spiral wire has few drawbacks seen in conventionally known vibrating bodies, and has solved the above-mentioned problems. I found out what I got.

That is, the present invention provides a coil formed in a flat and spiral shape, a substrate for fixing the coil to one side,
The gist of this invention is a structure of an electromagnetic vibrating body including a diaphragm stacked on the other side of a wire ring with an appropriate gap therebetween.

<Function of the invention> The electromagnetic vibrating body of the present invention has the following characteristics:
Alternatively, when energized by a power source whose direction changes periodically, an electromagnetic force is generated in the wire, and the wire attracts and repels the vibrating body according to the cycle, causing it to vibrate.

Furthermore, since the electromagnetic vibrating body of the present invention uses a flat and spiral wire, it has good heat dissipation, and even if it is continuously energized by such a power source for a long time, the wire will not burn out or the winding will be damaged. Hard to disconnect.

The present invention will be described below with reference to illustrated embodiments.

<Example> FIG. 1 is a side sectional view of one embodiment according to the present invention. In the figure, 1 is a wire ring, and the wire diameter is appropriate.
For example, it is formed by spirally winding a highly conductive wire such as a copper wire or an aluminum wire many times. At this time, each winding is formed so that the entire wire 1 is flat so that all the windings are on substantially the same plane in order to suppress the thickness of the wire 1 to the necessary minimum.

Since the wire ring 1 is configured in this way, when a power source such as an AC power source whose current changes periodically in magnitude and/or direction is connected to both ends of the wire ring 1, an electromagnetic force is generated perpendicular to the plane to which the wire wire 1 belongs. do. Therefore,
The wire ring 1 and the diaphragm 2 made of a ferromagnetic material sensitive to electromagnetic force are held together with an appropriate gap, and the diaphragm is arranged so that it returns to its original position when the attractive or repulsive force disappears. With this arrangement, the diaphragm 2 generates vibrations corresponding to the frequency at which the magnitude and/or direction of the current flowing through the wire ring 1 changes. The diaphragm 2 is typically sensitive to electromagnetic forces, e.g.
It is constructed by forming a ferromagnetic metal material such as iron or nickel into a plate shape.

Reference numeral 3 denotes a substrate, which is attached to one side of the coil 1 to fix the coil 1 integrally. The board 3 is
Generally, it is sufficient to use an elastic material such as hard resin, hard rubber, wood, or metal. In particular, when the substrate 3 is made of a ferromagnetic metal, this is extremely advantageous because the substrate 3 strengthens the electromagnetic force of the coil 1. be.

In order to hold the substrate 3 and the diaphragm 2 together with an appropriate gap, for example, either fix them at the periphery of the substrate 3 and the diaphragm 2 or at other appropriate locations with a support member such as a spring, or Alternatively, as shown in FIG. 1, the diaphragm 2 and the substrate 3 may be stacked on each other with the shock absorbing member 4 inserted into the gap between the wire 1 and the diaphragm 2. The buffer member 4 includes, for example, a sponge,
A soft and elastic material such as hard rubber, cloth, or paper is used. When interposing the buffer member 4,
There is an advantage that the restoring force of the diaphragm 2 and the substrate 3 is increased, so that the operation of the electromagnetic vibrator becomes smoother, and the buffer member 4 absorbs operational noise, improving the usability.

FIG. 2 is a side sectional view of another embodiment according to the invention. This example is basically the same as the one shown in Figure 1, but in this example, the vibration main body is the same as that shown in Figure 1 except that three wire rings 1 are superimposed. , and is housed in a container-shaped outer cover 5 having an opening. This outer cover 5 is used to integrally hold and protect the vibrating body, and is usually made of resin, rubber, wood, metal, or the like. In particular, when a metal jacket 5 is used, the jacket 5 forms a magnetic path for the wire ring 1 and increases its magnetomotive force, making it possible to obtain strong vibrations.

FIG. 3 is a side sectional view of yet another embodiment according to the invention. In this example, the substrate 3 is formed into a container shape with an opening at the upper end, and
Three wire rings 1 are attached to the inner bottom of the electromagnetic vibrating body, and the opening of the base plate 3 is covered with a diaphragm 2. Although this example has slightly lower vibration efficiency than the one shown in FIG. 2, it is possible to produce a robust and easy-to-handle electromagnetic vibrator at a low cost.

Next, a method of using the electromagnetic vibrator according to the present invention will be explained.

The electromagnetic vibrator of the present invention can be energized by applying an alternating current in which the direction of current flow is reversed at regular intervals, or a direct current whose magnitude increases or decreases at regular intervals. Such alternating current may not only have a general sinusoidal waveform, but also a pulsed current such as a rectangular waveform, a triangular waveform, and a barbed waveform. In addition, as direct current, for example, pulsating current obtained by rectifying the alternating current with a rectifying means such as a diode, or accumulated in a capacitor or battery by a switching element such as a thyristor whose conduction is controlled by a conduction control circuit. It may be obtained by intermittently discharging the charged charges.

FIG. 4 shows that the electromagnetic vibrator according to the present invention is connected to an AC power source AC via a switch circuit 6 and a diode D, which includes a time switch and a current adjustment circuit.
This is an example of an energizing circuit connected to. In this example, when the switch circuit 6 is closed, the alternating current from the AC power supply AC is half-wave rectified by the diode D, and a positive half cycle having the same period as the AC power supply AC is applied to the coil 1 in the electromagnetic vibrator. . As a result, the wire ring 1 periodically attracts the diaphragm 2 and vibrations are generated. To change the strength of vibration, the strength of the current flowing through the wire ring 1 is adjusted by a current adjustment circuit in the switch circuit 6.

FIG. 5 shows an example of an energizing circuit that connects the electromagnetic vibrator of the present invention to an alternating current power supply AC via a switch circuit 6 including a time switch and a continuity control circuit, and a main circuit of a reverse blocking three-terminal thyristor SCR. It is. In this example, when the switch circuit 6 is closed, it is built into the switch circuit 6. The conduction control circuit starts operating and intermittently conducts the main current path of the reverse blocking three-terminal thyristor SCR. As a result, the wire ring 1
A part or all of the positive half cycle of a sinusoidal alternating current from an alternating current power supply AC is applied periodically to
Vibration occurs due to the electromagnetic force generated at that time.
To change the strength of vibration, adjust the conduction angle of the reverse blocking three-terminal thyristor SCR using the conduction control circuit.
The current flowing through the coil 1 is adjusted.

FIG. 6 shows an example of an energizing circuit in which the vibration period of the electromagnetic vibrator can be appropriately selected within a certain range. As shown in FIG. 6, in this example, the input terminal of the bridge diode D is connected to the alternating current power supply AC via a switch circuit 6 including a time switch and a current adjustment circuit, while the output terminal of the bridge diode D Connect the smoothing capacitor _C1 in series at the end. The wire ring ₁ in the electromagnetic vibrator is connected to both ends of the smoothing capacitor C1 via an appropriate resistor R and the main circuit of the reverse blocking three-terminal thyristor SCR, and the series circuit is connected from the reverse blocking three-terminal thyristor SCR and the wire ring 1. is the pulse current generation capacitor C ₂
are connected in parallel. 0 is a low frequency oscillation circuit for controlling the conduction of the reverse blocking three-terminal thyristor SCR, and its output terminal is the reverse blocking three-terminal thyristor.
Connected to the gate pole of the SCR.

To explain the operation of this example, when the switch circuit 6 is closed, the sine wave alternating current from the alternating current power supply AC is full-wave rectified by the bridge diode D, and then smoothed by the smoothing capacitor _C1 . The direct current thus obtained is temporarily stored in the pulse current generating capacitor _C2 . In such a state, when the oscillation output of low-frequency oscillation circuit 0 is applied to the Kehate pole of the reverse-blocking three-terminal thyristor SCR, the reverse-blocking three-terminal thyristor SCR becomes conductive intermittently according to the oscillation cycle of the low-frequency oscillation circuit 0. .
Since the pulse current generating capacitor _C2 is discharged only when the main circuit of the reverse blocking three-terminal thyristor SCR is conductive, as a result, a pulse current corresponding to the oscillation period of the low frequency oscillation circuit 0 is generated in the coil 1. is applied, and the electromagnetic vibrating body also vibrates according to its oscillation period. Therefore, by appropriately adjusting the oscillation cycle of the low frequency oscillation circuit 0, vibration stimulation can be performed at an optimal cycle depending on the application. In order to change the strength of vibration, the current flowing through the wire ring 1 is adjusted by a current adjustment circuit provided in the switch circuit 6.

FIG. 7 shows an energizing circuit basically based on the same principle as that shown in FIG. 4, but in this example, as shown in FIG. 7, a set of electromagnetic vibrators 7, By inserting the changeover switches S ₁ and S ₂ into the electric circuit including one end of 7, 7, 7 and another set of electromagnetic vibrators 7', 7', 7', 7' connected in series with each other, the changeover switch can be activated. When S ₁ and S ₂ are switched as shown by the solid lines, the two sets of electromagnetic vibrators are connected in series,
On the other hand, when the changeover switches S ₁ and S ₂ are switched as shown by the broken lines, the two sets of electromagnetic vibrators are connected in parallel with each other, and the wires are connected so that the current flowing through the two sets of electromagnetic vibrators is doubled. Since this example is configured in this way, just by switching the changeover switches S ₁ and S ₂ ,
Easily change the vibration strength of two sets of electromagnetic vibrators to "strong" or "weak"
Can be switched.

As described above, the electromagnetic vibrating body of the present invention can be easily manufactured to be small and lightweight, has good heat dissipation, has low operating noise, and has little deterioration over time, so it is expected to have an extremely wide range of uses. For example, the electromagnetic vibrating body of this invention can be used to treat stiffness in the neck and shoulders, lower back pain, neuralgia, muscle pain, muscle pain, arthritis, sensitivity to cold, bed sores, etc.
When applied to rheumatism, the vibrations from the electromagnetic vibrator of this invention improve blood circulation in specific areas,
It promotes metabolism and is not only effective in reducing and eliminating pain and inflammation associated with these symptoms and diseases, but also in preventing some symptoms and diseases. For the same reason, the electromagnetic vibrating body of the present invention is also effective for warming up before exercise and for pine surge after exercise.

A distinctive feature of this invention is that the electromagnetic vibrator according to this invention is effective in regulating sleep in living organisms.
In other words, it was found that vibrations with a relatively long period promote sleep in living organisms, while vibrations with a relatively short period promote wakefulness. Therefore, the electromagnetic brake of the present invention is effective in promoting sleep onset and preventing night crying in infants. Furthermore, when the electromagnetic vibrating body of the present invention is attached to the seat or headrest of an automobile, etc., and the vibration period of the attached electromagnetic vibrating body is controlled by a time switch or a frequency switching circuit, it is possible to prevent the driver from falling asleep while driving. It can help you fall asleep while resting.

Vibrations per second may be administered for about 10 minutes to 2 hours, once or twice daily, for 1 to 2 months. On the other hand, when the purpose is to give a pine surge before and after exercise, the vibration of the above-mentioned period may be administered for about 10 to 1 hour each time. If the purpose of administration is sleep regulation,
It is sufficient to induce sleep by administering vibrations at a frequency of approximately 50 to 120 times/second from approximately 30 minutes before falling asleep to approximately 30 minutes after falling asleep, or throughout the entire sleep period. Or about 30 minutes before waking up,
Immediately after awakening or throughout the entire awakening period, 120 times/
Vibrations with a period exceeding 280 times/second may be administered. At that time, it is best to start strong and gradually weaken.

In either case, when administered to acupuncture points closely related to the target symptom, disease, or site, extremely significant effects may be produced. Furthermore, depending on the case, the magnetic force or weak sound radiated by the coil may work together with the vibration stimulation to produce a remarkable effect that cannot be achieved by vibration stimulation alone.
