Description

[Technical Field]

[0001] The present invention relates to a vibration device and a method for transmitting vibrations to the body. [Background technology]

[0002] Conventionally, for example, there are known technologies such as the bone vibration sensation device and method of using it disclosed in Patent Document 1, and the low-frequency vibration device, furniture with a built-in low-frequency vibration device, and transportation with a built-in low-frequency vibration device in the seats disclosed in Patent Document 2, which are connected to a content playback device that plays audio signals via an amplifier and receive low-frequency signals in the human audible range from among the audio signals to generate vibrations, which are then transmitted to the body or conducted to the bones.

[0003] Also, as disclosed in Patent Document 3, a massage probe is known that includes a pair of electrodes and can apply current from the electrodes when power is supplied from a massage machine. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2020-043393 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-346476 [Patent Document 3] Japanese Patent Application Publication No. 2018-000656 Summary of the Invention [Problem to be solved by the invention]

[0005] However, all of these methods were limited to transmitting vibrations to the inside of the body and bones using only sound, and sound itself was not used as an energy source to transmit other types of stimuli to the body; other types of stimuli required a separate power supply.

[0006] The present invention has been made in view of the above points, and its object is to effectively utilize vibrations generated by a reproduced signal. [Means for solving the problem]

[0007] In order to achieve the above object, in the present invention, a weak current is generated along with vibrations in response to a playback signal.

[0008] Specifically, in the first aspect of the present invention, a vibration generating unit having a vibrator that vibrates in accordance with a playback signal; a power generating unit having a piezoelectric element that generates a weak current corresponding to the playback signal by vibration of the vibration generating unit; an electromagnetic wave generating unit having a coil unit into which a weak current generated by the power generating unit flows; a main body having a housing that houses the vibration generating unit, the power generating unit, and the electromagnetic wave generating unit; The electromagnetic wave generating section is configured so as to radiate weak electromagnetic waves into space.

[0009] According to the above configuration, the vibrations generated by the vibrator of the vibration generating unit are converted into electricity by a power generating unit having a piezoelectric element such as a piezo element. Specifically, air vibrations due to conduction from the housing or airborne propagation are transmitted to the piezoelectric element, and a weak current generated by the piezoelectric element flows through the coil, generating minute electromagnetic waves that can be irradiated onto the body. The vibrations and electromagnetic waves can also be irradiated onto liquids such as water. The vibrations generated by the playback signal are simultaneously applied to different areas as sound waves and electromagnetic waves. On the other hand, the radiation emitted by the electromagnetic wave generating unit is minute compared to the energy generated by the vibration generating unit. For the purpose of electromagnetic wave therapy, this device can have the effects of both sound vibrations and the electromagnetic waves derived from them. The radiation emitted by the electromagnetic wave generating unit is so minute that it is at a level that does not cause discomfort to the human body compared to typical electromagnetic waves. On the other hand, this approach involves causing subtle changes in physical properties, with the primary effect being through vibrations (sound waves) and the secondary effect being in the electromagnetic wave domain.

[0010] In the second invention, in the first invention, the main body portion has a detachable attachment portion, The vibration generated by the vibration generating unit is configured to be transmitted to the body via the attachment unit.

[0011] According to the above configuration, for example, by attaching an attachment part with an uneven surface and locally contacting this attachment part with the target (the so-called affected part in the case of the body), vibration can be transmitted effectively.

[0012] In the third invention, in the first invention, the main body has a detachable attachment portion for accommodating a container containing water; The vibrations generated by the vibration generating unit and the weak electromagnetic waves generated by the electromagnetic wave generating unit are transmitted to the water in the container housed in the attachment unit.

[0013] The above configuration facilitates specialized research into vibrations, weak electromagnetic waves, and their effects on water's physical properties. If certain properties are activated by applying vibrations or weak electromagnetic waves to water, it would be a useful experiment to verify whether or not drinking the beverage causes any changes in perception.

[0014] In the fourth invention, a vibration generating unit having a vibrator that vibrates in accordance with a playback signal; a power generating unit having a piezoelectric element that generates a weak current corresponding to the playback signal by vibration of the vibration generating unit; a main body having a housing that houses the vibration generating unit and the power generating unit, The vibration generated by the vibration generating unit is transmitted to the body via the housing or an attachment unit attached to the housing, and The weak current generated by the piezoelectric element is transmitted to the body via the attachment portion.

[0015] With the above configuration, vibrations can be effectively transmitted to the body via the attachment, and a weak current can be transmitted to the body, thereby reducing injury and pain. A weak current does not cause the tingling sensation that occurs with low-frequency waves, and is expected to have the effect of accelerating the recovery of body tissue.

[0016] In a fifth aspect of the present invention, in any one of the first to fourth aspects of the present invention, The main body is configured to transmit the playback signal to a vibration generating unit of a vibration device wirelessly or via a recording medium.

[0017] With the above configuration, you can easily use your preferred playback signal with the vibration device. If it is wireless, it can be controlled with a smartphone app, and multiple files can be selectively played sequentially depending on the purpose.

[0018] In a sixth aspect of the present invention, in any one of the first to fifth aspects of the present invention, The reproduction signal includes a non-periodic continuous signal in which analog waveforms having different fundamental periods are arranged in succession, one period at a time.

[0019] The above configuration prevents the body from becoming accustomed to the periodic signal, eliminating the need for periodic replacement of stimuli, which is particularly effective in treating bone fractures.

[0020] In the seventh invention of a method for transmitting vibration, The regenerated signal generates vibrations and a weak current, which are then transmitted to the body.

[0021] According to the above configuration, transmitting vibrations from the playback signal to the body and also transmitting a weak current to the body can help reduce injuries and pain. The weak current does not cause the tingling sensation that occurs with low-frequency waves, and is expected to have the effect of accelerating the recovery of body tissue.

[0022] In an eighth aspect of the present invention, in the seventh aspect of the present invention, The vibration and the weak current are transmitted directly or indirectly to the body, and the weak current generated by the vibration generates weak electromagnetic waves that are irradiated onto the body.

[0023] In the ninth invention, A reproduction signal generates vibration and a weak current, and the weak current generated by the vibration generates a weak electromagnetic wave, The vibration is transmitted directly or indirectly to the body, and the weak electromagnetic waves are irradiated onto the body.

[0024] With these configurations, the vibrations caused by the playback signal are applied simultaneously to different regions as sound waves and electromagnetic waves. For the purpose of electromagnetic wave therapy, the body can be affected by both sound vibrations and the electromagnetic waves derived from them. The radiation emitted by the electromagnetic wave generator is extremely subtle, so it is at a level that does not cause discomfort to the human body compared to ordinary electromagnetic waves. On the other hand, this is an approach that causes subtle changes to physical properties, and has the characteristic of having a primary effect through vibrations (sound waves) and a secondary effect in the electromagnetic wave region.

[0025] In a tenth aspect of the present invention, in any one of the seventh to ninth aspects of the present invention, The reproduction signal is a non-periodic continuous signal in which analog waveforms having different fundamental periods are arranged in succession, one period at a time.

[0026] The above configuration prevents the body from becoming accustomed to the periodic signal, eliminating the need for periodic replacement of stimuli, which is particularly effective in treating bone fractures. [Effects of the Invention]

[0027] As described above, according to the present invention, it is possible to effectively utilize the vibration and weak current generated by the reproduced signal. [Brief explanation of the drawings]

[0029] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0030] (Embodiment 1) 1 shows a vibration device 1 according to a first embodiment of the present invention. The vibration device 1 has a main body 4 including a cylindrical housing 2 made of, for example, a resin molded product and a bottom cover 3 that closes the bottom of the housing 2. The housing 2 may be manufactured using a 3D printer or injection molding. The housing 2 may also be made of metal such as stainless steel or titanium.

[0031] The main body 4 contains a vibration generating unit 10, a power generating unit 20, and an electromagnetic wave generating unit 30 inside.

[0032] The vibration device 1 has a transmission unit 5 that wirelessly transmits the playback signal to a vibration generation unit 10. The transmission unit 5 is, for example, a wireless communication device using Bluetooth (registered trademark), such as a smartphone 6 or a personal computer 7. Specifically, a sound source file containing the playback signal downloaded to the smartphone 6 or the personal computer 7 is transmitted to the vibration generation unit 10 via Bluetooth. The smartphone 6 or the personal computer 7 has a playback signal data storage unit 9 that stores the playback signal in a memory or the like.

[0033] -About playback-only files- The playback signal contained in the dedicated file prepared specifically to produce an effect for this vibration device 1 can be either a periodic or non-periodic signal, but it can also be a sound source in the low frequency range, which makes vibrations more noticeable, or a sound source rich in harmonics, such as a crystal bowl.

[0034] Furthermore, for example, the playback signal may include a non-periodic continuous signal in which analog waveforms with different fundamental periods are arranged in succession, one cycle at a time, as in Patent No. 6656648. In this case, the body is prevented from becoming accustomed to the periodic signal, and regular switching of stimuli, which is particularly effective in treating bone fractures, is not necessary.

[0035] For example, as described above, by connecting the smartphone 6 and the vibration generating unit 10 via Bluetooth, it becomes possible to control it using a smartphone app, and it becomes possible to sequentially and selectively play back a variety of multiple files depending on the application.

[0036] -Configuration of vibration generating unit- The vibration generating unit 10 vibrates in accordance with the various playback signals described above, and as shown in an enlarged outline in Figure 2, it is equipped with a transmission data receiving unit 11 as a transmission data receiving means, and an audio amplification playback unit 12 that amplifies the data received by this transmission data receiving unit 11.

[0037] The vibration generating unit 10 includes an upper speaker 13 and a bass speaker 14 as vibrators that reproduce the reproduction signal amplified by the audio amplifying and reproducing unit 12. Note that the means for generating a signal from the reproduction signal may not be a speaker that reproduces sound, but may be a vibration generating device such as a vibrotransducer as disclosed in Patent Document 1.

[0038] The bass sound from the bass speaker 14 is emitted from an opening 15. The sound from the upper speaker 13 is emitted from a grill 16 at the upper end of the vibration generating unit 10. There are no particular limitations on the configuration of the upper speaker 13, but it is preferable that the upper speaker 13 has a different configuration from that of the bass speaker 14. The speaker configuration is not limited to this, and the number of speakers may be one, or three or more.

[0039] Although not shown in detail, the vibration generating unit 10 is supplied with power from a power source such as a rechargeable battery. This power is supplied when a switch 8 is turned on. A switch opening 2a is provided in the housing 2 to coincide with this switch 8.

[0040] -Configuration of power generation unit- 1, the power generating unit 20 has a piezoelectric element 21, also known as a piezo element. The piezoelectric element 21 has a piezoelectric body made of quartz crystal or ferroelectric ceramics, and generates a weak current from an electric wire connected to the piezoelectric body when it receives vibration. Therefore, the power generating unit 20 can generate a weak current corresponding to the playback signal by using the vibration of the vibration generating unit 10.

[0041] -Configuration of the electromagnetic wave generating unit- The vibration device 1 also includes an electromagnetic wave generating unit 30 having a coil unit 31 into which a weak current generated by the power generating unit 20 flows. In this embodiment, the coil unit 31 may use a coil substrate also known as a zero magnetic field coil, as described in Japanese Patent No. 6624702, or may use a normal spiral coil substrate.

[0042] The electromagnetic wave generating section 30 is arranged so that the weak electromagnetic waves generated by the coil section 31 are radiated into space.

[0043] -Activation of vibration device- Next, the operation of the vibration device 1 according to this embodiment will be described.

[0044] In this embodiment, a playback signal generates vibrations and a weak current, which are transmitted directly or indirectly to the body, and weak electromagnetic waves generated by the weak current generated by the vibrations are irradiated onto the body.

[0045] Specifically, as shown in Fig. 2, a desired playback signal is downloaded in advance to a playback signal data storage unit 9 of a smartphone 6 or a personal computer 7. The playback signal may be a non-periodic continuous signal in which analog waveforms having different fundamental periods are arranged in succession, one period at a time.

[0046] Then, when in use, playback signal data is transmitted to the vibration device 1 using, for example, Bluetooth (registered trademark). In this embodiment, a preferred playback signal can be easily used with the vibration device 1. If it is wireless, it can be controlled using a smartphone app, and multiple files can be sequentially and selectively played back according to the purpose.

[0047] The transmission data receiving section 11 of the vibration generating section 10 receives the reproduction signal data, the sound is amplified by the sound amplifying and reproducing section 12, and the signal is sent to the upper speaker 13 and the bass reproducing speaker 14.

[0048] Then, sound corresponding to the playback signal is emitted, causing the housing 2 to vibrate and the surrounding air to vibrate.

[0049] In response to the vibration, the piezoelectric element 21 of the power generating section 20 generates a weak current corresponding to the playback signal.

[0050] Then, the weak current is sent through the electric wire to the coil portion 31 of the electromagnetic wave generating portion 30. The coil portion 31 generates a weak electromagnetic wave corresponding to the weak current.

[0051] In this state, vibrations and weak currents are transmitted directly or indirectly to the body via the housing 2, and weak electromagnetic waves generated by the weak currents generated by the vibrations are irradiated onto the body. At this time, weak electromagnetic waves corresponding to the playback signal supplied to the vibration generating unit 10 are generated. Furthermore, when the housing 2 is directly attached or pressed against an object (such as the body), the vibrations transmitted to the piezoelectric element 21 vary depending on the degree of attachment. In other words, it is recognized that the intensity of the irradiated electromagnetic waves changes depending on the relationship with the object.

[0052] In this way, in this embodiment, air vibrations due to conduction from the housing 2 or propagation through the air are transmitted to the piezoelectric element 21, and a weak current generated in the piezoelectric element 21 flows through the coil portion 31, generating a minute electromagnetic wave, which can then be irradiated onto the body.

[0053] The vibrations caused by the playback signal are applied simultaneously in different regions as sound waves and electromagnetic waves.

[0054] On the one hand, the radiation emitted by the electromagnetic wave generating unit 30 is minute compared to the energy generated by the vibration generating unit 10. With this device, for the purpose of electromagnetic wave treatment, it is possible to exert the effects of both sonic vibrations and the electromagnetic waves derived from them. Because the radiation emitted by the electromagnetic wave generating unit 30 is extremely minute, it is at a level that does not cause discomfort to the human body as with ordinary electromagnetic waves. On the other hand, it is an approach that produces subtle changes in physical properties, and has the characteristic of having a primary effect through vibrations (sound waves) and a secondary effect in the electromagnetic wave region.

[0055] If the playback signal includes a non-periodic continuous signal in which analog waveforms with different fundamental periods are arranged in succession, this prevents the body from becoming accustomed to periodic signals, eliminating the need for periodic switching of stimuli, which is particularly effective in treating fractures.

[0056] Therefore, the vibration device 1 according to this embodiment can effectively utilize the vibration and weak current generated by the playback signal.

[0057] -Variation 1- 4 and 5 show a vibration device 1' according to a modified example of the embodiment of the present invention, which differs from the above-described embodiment 1 in that it is provided with a vibration transmission attachment 40. In the following modified examples and embodiments, the same parts as those in FIGS. 1 to 3 are designated by the same reference numerals, and detailed description thereof will be omitted.

[0058] The main body 4 has a vibration transmission attachment 40 as a detachable attachment. The shape and material of this vibration transmission attachment 40 are not particularly limited, but it may be made, for example, of a press-molded dome-shaped stainless steel plate. The vibration transmission attachment 40 may be a resin molded product, or may be made of a material that is less likely to cause metal allergies, such as titanium.

[0059] In this modification, vibrations generated by the vibration generating unit 10 are effectively transmitted by pressing the vibration transmission attachment 40 against the required part of the body. Vibrations can be transmitted effectively by locally contacting the vibration transmission attachment 40 with the target (the so-called affected part of the body). For example, the attachment 40 can be pressed with an appropriate force against a part of the ribs that feels comfortable when pressed against.

[0060] -Variation 2- FIG. 6 shows a second modification of the first embodiment of the present invention, which differs from the first embodiment in that a container insertion attachment 41 is provided.

[0061] The container insertion attachment 41 of this modified example is, for example, a resin molded product that can be molded into complex shapes at low cost, and has four rod-shaped container support members 41a on the upper side of a cylindrical body, the base ends of which are connected to a honeycomb-shaped mounting member 41b on which the bottom of the container is placed. The shape of the holes in the mounting member is not limited to a honeycomb shape. If a switch exposure opening 41c is provided to expose the switch 8 of the vibration device 1, excellent operability will be achieved.

[0062] This modified example can also be applied to transmitting vibrations of a special pattern to water. The container insertion attachment 41, which is optimized for beverages, can be inserted with, for example, a plastic bottle (not shown).

[0063] There is a specialized field of research into vibrations in water and their effect on its physical properties, and this device also facilitates such experiments.

[0064] If certain properties are activated by vibrating water, it would be a valid experiment to verify whether or not drinking the beverage changes perception.

[0065] In addition, since the human body is mostly made up of water, changes in water content are also recognized as an important field of research in terms of their effects on the body. However, the liquid in question does not necessarily have to be water.

[0066] (Embodiment 2) 9 to 11 show a vibration device 101 according to a second embodiment of the present invention, which differs from the vibration device 1 of the first embodiment in that the method of transmitting a reproduction signal is different.

[0067] In this embodiment, instead of using a wireless communication means as a means for transmitting a playback signal as in embodiment 1, a recording medium 109 such as an SD (registered trademark) card is used as a playback signal recording data storage unit, and the data is transmitted to a vibration generating unit 110.

[0068] Specifically, in this embodiment, the housing 2 is provided with a card insertion section serving as the transmitter 105. The transmitter 105 has a playback signal storage data reading section 111, which reads the playback signal storage data from the SD card. The playback signal is then amplified by the audio amplification playback section 12 and transmitted to the upper speaker 13 and the bass playback speaker 14, similar to the first embodiment.

[0069] Since the method of reading the playback signal is the same as that of the first embodiment, a description of the operation of the vibration device 101 of this embodiment will be omitted, but the same effects as those of the first embodiment can be obtained in this embodiment as well.

[0070] (Embodiment 3) FIG. 12 shows a vibration device 201 according to a second embodiment of the present invention, which differs from the first and second embodiments in that the coil portion 31 is not provided.

[0071] In this embodiment, a weak current generated in the piezoelectric element 21 by vibration is not passed through the coil portion 31 but is passed directly to the vibration transmitting attachment 40 .

[0072] This embodiment can be said to be an embodiment specialized for therapeutic purposes using vibration and weak current.

[0073] In this embodiment, when the switch 8 is turned on, the upper speaker 13 and the bass speaker 14 vibrate in accordance with the playback signal, and this vibration causes the piezoelectric element 21 to generate a weak current corresponding to the playback signal.

[0074] The vibration transmission attachment 40 is made of metal, and a weak current flows into it from the piezoelectric element 21. Therefore, when the vibration transmission attachment 40 is pressed against the body, the vibration is transmitted and a weak current flows into the body.

[0075] In this way, injuries and pain can be alleviated by transmitting vibrations to the body via the vibration transmission attachment 40, as well as transmitting a weak current to the body. A weak current does not cause the tingling sensation that occurs with low frequency waves, and is expected to have the effect of accelerating the recovery of body tissues.

[0076] Therefore, the vibration device 201 according to this embodiment can also effectively utilize the vibration and weak current generated by the playback signal.

[0077] As explained above, the vibration devices 1, 1', 101, 201 of the present invention can be used for body massage, fascia relaxation, relaxation, and for imparting vibrations to water (general liquids such as drinking water, alcohol, and agricultural water), and are small, palm-sized devices that transmit vibrations using sound energy and also have the function of generating electromotive force through vibration, allowing them to impart weak electrical stimulation to the human body in response to the complex patterns of various sound sources.

[0078] It should be noted that the above-described embodiments are essentially preferred examples and are not intended to limit the scope of the present invention, its applications, or uses. [Explanation of symbols]
