Detailed Embodiments

[0024] Hereinafter, each embodiment of the present invention will be described with reference to the accompanying drawings. In addition, regarding the descriptions in the specifications and drawings of each embodiment, for constituent elements having substantially the same or corresponding functional structures, duplicate explanations may sometimes be omitted by assigning the same or corresponding symbols.

[0025] In directions such as parallel, right-angled, orthogonal, horizontal, vertical, up and down, left and right, and front and back, deviations within a range that does not impair the effects of the embodiment are allowed. The shape of the corners is not limited to right angles and may have rounded corners. Parallel, right-angled, orthogonal, horizontal, and vertical may respectively include substantially parallel, substantially right-angled, substantially orthogonal, substantially horizontal, and substantially vertical.

[0026] For example, substantially parallel means that even if two lines or two surfaces are not completely parallel to each other, they can be regarded as parallel to each other within the range allowable in manufacturing. For each of the other substantially right-angled, substantially orthogonal, substantially horizontal, and substantially vertical, similar to substantially parallel, it is intended that as long as the mutual positional relationship between two lines or two surfaces is within the range allowable in manufacturing, they respectively conform.

[0027] In addition, for the sake of convenience in explanation, a virtual three-dimensional coordinate system (XYZ orthogonal coordinate system) composed of mutually orthogonal X-axis, Y-axis, and Z-axis (XYZ axes) is set in the accompanying drawings. For example, for the coordinate axis perpendicular to the plane of the accompanying drawings, when a black circle is shown in the circle of the coordinate axis, it indicates that the coordinate axis faces the front side with respect to the plane of the paper. In addition, when a cross-shaped circle is shown in the circle of the coordinate axis, it indicates that the coordinate axis faces the inside with respect to the plane of the paper.

[0028] However, this coordinate system is set for the purpose of explanation and does not limit the posture of the beauty device and the like related to the present embodiment. In addition, sometimes a view of an object observed along the X-axis direction from the +X side along the opposite direction of the X-axis is referred to as a front view.

[0029] 《First Embodiment》

[0030] The beauty device related to the first embodiment will be described. The beauty device related to the first embodiment is a wearable beauty device worn by a user. The beauty device related to the first embodiment includes a cover, an ultrasonic emission unit, a light irradiation unit, and a protection member. In the beauty device related to the first embodiment, the ultrasonic emission unit is provided on the inner surface of the surface on the user side in the cover when worn by the user, and emits ultrasonic waves toward the first part of the user. In the beauty device related to the first embodiment, the light irradiation unit is provided on the inner surface and irradiates light toward the second part of the user.

[0031] The protection member in the beauty device related to the first embodiment, for example, protects the user's eyes from ultrasonic waves and light. The protection member is, for example, provided on the inner surface of the cover and is arranged to surround the user's eyes when the cover is worn by the user. The protection member in the beauty device related to the first embodiment includes a material with an acoustic impedance of 5×10 6 Pascal seconds per cubic meter or more.

[0032] In the above Patent Documents 1 to 4, the idea of protecting a part of the user's body from the influence of ultrasonic waves is not disclosed. In Patent Document 4, it is disclosed that conductive rubber is used to prevent light from entering the eyes. However, the absolute value of the difference in acoustic impedance between conductive rubber and air is relatively small. Therefore, it is difficult to use conductive rubber to sufficiently block ultrasonic waves. In contrast, in the present embodiment, a material or member that satisfies specific conditions related to the reflection and / or attenuation of acoustic impedance is used for at least a part of the protection member. Thereby, a part of the user's body (sometimes referred to as the protected part) can be protected from the influence of ultrasonic waves emitted by the beauty device. In addition, when a material or member that satisfies specific conditions related to the light transmittance is used for at least a part of the protection member, the above-mentioned protected part can be protected from the influence of ultrasonic waves and light emitted by the beauty device.

[0033] As the part to be protected, the eyes can be exemplified. In the countries where the beauty device 1 is sold or used, the part to be protected may be a part where there are restrictions on the irradiation of ultrasonic waves and / or light.

[0034] The beauty device according to the first embodiment will be described with reference to the drawings. Figure 1 It is a perspective view showing an outline of a beauty device 1 as an example of the beauty device according to the first embodiment. Figure 2 It is a front view showing an outline of a beauty device 1 as an example of the beauty device according to the first embodiment. Figure 3 It is a rear view showing an outline of a beauty device 1 as an example of the beauty device according to the first embodiment. Figure 4 It is a perspective view showing an outline of a beauty device 1 as an example of the beauty device according to the first embodiment.

[0035] In the present embodiment, the beauty device 1 is a wearable beauty device worn by a user. For example, the beauty device 1 is configured to be wearable on a part of the user's body. Therefore, the user can operate the beauty device 1 while wearing the beauty device 1. As a result, the user can perform operations other than beauty operations during the operation of the beauty device 1. In the case where the beauty device 1 is configured to be divisible into a plurality of devices, as a way of wearing the beauty device 1 on the user, it may include a way of wearing all of these plurality of devices and a way of wearing at least one of these plurality of devices on the user.

[0036] As Figure 1 shown, the beauty device 1 is, for example, a mask-type beauty device worn on the user's head. As the user's head, at least one of the face, head, and neck can be exemplified. In the present embodiment, the beauty device 1 irradiates light onto the user's face. In addition, the beauty device 1 emits ultrasonic waves toward the user's face. The beauty device 1 may emit ultrasonic waves into the air toward the user's face. In this case, the ultrasonic waves emitted from the beauty device 1 propagate in the air and reach the user's face.

[0037] In the present embodiment, the beauty device 1 includes a cover member 10, one or more (sometimes referred to as one or more) ultrasonic wave emission parts 20, one or more light irradiation parts 30, and a protection member 40. Each component in the beauty device 1 will be described in detail.

[0038] [Cover member 10]

[0039] In the present embodiment, the cover member 10 is configured to be wearable by a user. The cover member 10 is configured to be freely detachable by the user. For example, the cover member 10 is configured to cover the user's face when the beauty device 1 is used. According to the present embodiment, the user can wear the beauty device 1 by wearing the cover member 10 on the user's head.

[0040] In the present embodiment, one or more ultrasonic emission parts 20 and one or more light irradiation parts 30 are arranged on the cover member 10. In the present embodiment, the cover member 10 supports one or more ultrasonic emission parts 20 and one or more light irradiation parts 30.

[0041] In the present embodiment, the cover member 10 supports one or more ultrasonic emission parts 20 and one or more light irradiation parts 30 such that when the beauty device 1 is worn by the user, the ultrasonic waves emitted from at least one of the one or more ultrasonic emission parts 20 (sometimes referred to as irradiation, emission, ejection, etc.) and the light emitted from at least one of the one or more light irradiation parts 30 (sometimes referred to as irradiation, emission, ejection, etc.) reach a part of the user's body (sometimes referred to as the target part). Thus, for example, in a state where the beauty device 1 is worn by the user, upon receiving an instruction to emit ultrasonic waves and / or light from the beauty device 1, ultrasonic waves and / or light are emitted from the beauty device 1 toward the target part. The timing of emitting ultrasonic waves and the timing of emitting light may be substantially the same or different.

[0042] The target part may be a single part or two or more parts. As the target part, the entire face, the entire face (excluding the protected part), the forehead, the frontal angle, the cheeks, the nose, nasolabial folds, and / or facial lines, etc. may be exemplified. The target part may be a part adjacent to the above-mentioned protected part, or the target part may be set to surround the protected part.

[0043] In the present embodiment, the cover member 10 supports one or more ultrasonic emission parts 20 in such a manner that when the beauty device 1 is worn by the user, the above-mentioned target part is separated from the ultrasonic emission part 20 that emits ultrasonic waves toward the target part. Similarly, the cover member 10 supports one or more light irradiation parts 30 in such a manner that when the beauty device 1 is worn by the user, the above-mentioned target part is separated from the light irradiation part 30 that emits light toward the target part. Thereby, a wearable device having one or more ultrasonic emission parts 20 and one or more light irradiation parts 30 can be realized.

[0044] The cover member 10 has an outer surface 10A that becomes the outside when worn by the user and an inner surface 10B that is the surface on the user side.

[0045] When the cover member 10 is worn by a user, at positions corresponding to the eyes, there are openings 10e1 and 10e2 that penetrate the cover member 10. The openings 10e1 and 10e2 may be open without any elements provided, or elements such as a transparent plate, a semi-reflective mirror, a filter screen, etc. may be provided.

[0046] In addition, when the cover member 10 is worn by a user, at a position corresponding to the nose, there is an opening 10n that penetrates the cover member 10. The cover member 10 is provided with a net-like member 10n1 (filter screen) that closes the opening 10n at the opening 10n. In addition, when the cover member 10 is worn by a user, at a position corresponding to the mouth, there is an opening 10m that penetrates the cover member 10. The cover member 10 is provided with a net-like member 10m1 (filter screen) that closes the opening 10m at the opening 10m. Additionally, each of the openings 10n and 10m may also be open without anything provided.

[0047] In addition, the openings 10e1 and 10e2 are each an example of a first opening, and the openings 10m and 10n are each an example of a second opening.

[0048] The specific acoustic impedance of each of the net-like member 10n1 and the net-like member 10m1 is preferably 5×10 6 Pascal seconds per cubic meter or more. The specific acoustic impedance of air is approximately 430 Pascal seconds per cubic meter. Therefore, by increasing the difference from the specific acoustic impedance of air, it is possible to increase the reflection of ultrasonic waves at the boundaries between each of the net-like member 10n1 and the net-like member 10m1 and air.

[0049] In addition, the specific acoustic impedance of the material constituting the net-like member (net-like member 10n1, net-like member 10m1) may be set to 5×10 6 Pascal seconds per cubic meter or more, so that the specific acoustic impedance of the net-like member is 5×10 6 Pascal seconds per cubic meter or more. In addition, a material with a specific acoustic impedance of 5×10 6 Pascal seconds per cubic meter or more may be vapor-deposited on the surface of the material constituting the net-like member, so that the specific acoustic impedance of the net-like member is 5×10 6 Pascal seconds per cubic meter or more. Materials with a specific acoustic impedance of 5×10 6 Pascal seconds per cubic meter or more are, for example, copper, aluminum, etc.

[0050] The cover member 10 is formed of, for example, resin. The cover member 10 is, for example, acrylonitrile-butadiene-styrene resin (ABS resin), polycarbonate (PC), polypropylene (PP), polyethylene terephthalate (PET), polyoxymethylene (POM), poly(1,4-cyclohexanedimethylene terephthalate) (PCT), fiber reinforced plastics (FRP), polybutylene succinate (PBS), or a combination thereof.

[0051] The cover member 10 can also be formed of metal, for example. The cover member 10 can also contain, for example, stainless steel (SUS), titanium (Ti), iron (Fe), aluminum (Al), or a combination thereof.

[0052] In addition, the cover member 10 is formed to cover the entire face of the user (full size), but the cover member in the beauty device according to the first embodiment can also be formed to cover the upper half or the lower half of the face (half size), for example.

[0053] The cover member 10 includes straps 11 and 12 for fixing the cover member 10 when the cover member 10 is worn on the face of the user. When the beauty device 1 is worn on the user, the strap 11 physically contacts a part of the user's body (sometimes referred to as the wearing part). When the beauty device 1 is worn on the user, the strap 12 physically contacts the wearing part of the user. Thus, the beauty device 1 or the cover member 10 configured to be wearable on the user is realized.

[0054] In this embodiment, the straps 11 and 12 are joined at the back of the user's head. The straps 11 and 12 are joined at the back of the user's head, so that the cover member 10 is fixed to the user. The joining of the strap 11 and the strap 12 can be achieved, for example, by using a surface fastener, a thread fastener, a hook, a button, a snap, a magnetic button, or the like. In addition, the joining of the strap 11 and the strap 12 can also be performed, for example, by connecting the strap 11 and the strap 12.

[0055] The beauty device 1 can also include a coupling force adjustment unit (not shown) for adjusting the coupling force of the strap 11 and the strap 12. The coupling force adjustment unit can electrically tighten or loosen the straps 11 and 12.

[0056] The beauty device 1 can be an example of a device. The cover 10 can be an example of a main body or a support part. The strap 11 can be an example of a wearing part. The strap 12 can be an example of a wearing part. A structure having at least one of the cover 10, the strap 11, and the strap 12 can be an example of a main body. At least one of the one or more ultrasonic emission parts 20 can be an example of an ultrasonic emitting part. At least one of the one or more light irradiation parts 30 can be an example of a light emitting part. The protection member 40 can be an example of a protection part or a wearing part. The user's face can be an example of a target part. The user's eyes can be an example of a protected part. The first part can be an example of a target part. The second part can be an example of a target part. The first part and the second part can occupy different regions of the user's body.

[0057] [Ultrasonic emission part 20]

[0058] When the beauty device 1 is worn by the user, the ultrasonic emission part 20 emits ultrasonic waves toward the user's face. The beauty device 1 has a plurality of ultrasonic emission parts 20 on the inner surface 10B of the cover 10. The number of the ultrasonic emission parts 20 is, for example, from 1 to 500.

[0059] The ultrasonic emission part 20 emits, for example, sound in the range of 10 kHz to 50 kHz toward the user's skin. For example, the ultrasonic emission part 20 particularly preferably emits ultrasonic waves around 20 kHz. In addition, the ultrasonic emission part 20 emits, for example, ultrasonic waves with a sound pressure level in the range of 20 dB to 100 dB toward the user's skin. For example, the ultrasonic emission part 20 particularly preferably emits ultrasonic waves with a sound pressure level of 70 dB.

[0060] The range in which one ultrasonic emission part 20 irradiates ultrasonic waves can be, for example, in the range of 1 mm to 10 mm in diameter when the ultrasonic waves are concentrated. In addition, the range in which one ultrasonic emission part 20 irradiates ultrasonic waves can be, for example, in the range of 10 mm to 300 mm in diameter when the ultrasonic waves are diffused.

[0061] The ultrasonic emission part 20 may also include an ultrasonic oscillator that emits ultrasonic waves and a first irradiation range adjustment part for adjusting the irradiation range of the ultrasonic waves emitted from the ultrasonic oscillator. Examples of the first irradiation range adjustment part include (a) a reflector or a variable-focus lens; (b) an actuator for adjusting (i) the distance between the output end of the ultrasonic oscillator and the inner surface 10B of the cover 10, and / or (ii) the posture of the ultrasonic oscillator. Examples of the variable-focus lens include a reflector array (including a micromirror array).

[0062] The ultrasonic emission part 20 emits ultrasonic waves, for example, toward a part (sometimes referred to as the first part) including at least any one of the forehead, the frontal angle, the cheeks, the nose, the nasolabial folds, and the facial lines.

[0063] The ultrasonic emission unit 20 can be configured to be movable within the cover member 10. For example, the ultrasonic emission unit 20 is configured to be slidably movable within the cover member 10. The ultrasonic emission unit 20 can be configured to be detachable and attachable at a predetermined position of the cover member 10. The ultrasonic emission unit 20 can be configured to be rotatable relative to the cover member 10.

[0064] The ultrasonic emission unit 20 can also be set, for example, at a distance in the range of 5 mm to 50 mm from the face.

[0065] When the distance from the ultrasonic emission unit 20 to the user's skin changes, the effect on the skin may change. For example, when the distance from the ultrasonic emission unit 20 to the user's skin changes, sometimes an appropriate sound pressure for the skin may not be achieved. Therefore, the beauty device 1 can also be configured to measure the distance from the ultrasonic emission unit 20 to the user's skin. For the measurement of the distance, for example, a microphone or the like can be used to detect the sound emitted from the ultrasonic emission unit 20, and the distance can be calculated based on the returned time. In addition, the measurement of the distance can also be performed using other detectors such as a laser rangefinder or an ultrasonic rangefinder.

[0066] According to the present embodiment, a plurality of ultrasonic emission units 20 can be used simultaneously. Due to manufacturing errors, mass production variations, etc. of the plurality of ultrasonic emission units 20, the natural frequencies of the plurality of ultrasonic emission units 20 may sometimes be slightly different. In this case, due to the frequency difference, it is also considered that the sound waves may interfere and generate a hum. When a hum with a frequency of several Hz is generated, it is also considered that the user may feel uncomfortable with the hum.

[0067] Therefore, according to one embodiment, the control device of the beauty device 1 (for example, the overall control unit 110 described later) controls the operations of the plurality of ultrasonic emission units 20 such that, within the frequency range of the ultrasonic waves irradiated to the user, the absolute value of the difference in frequency between the plurality of ultrasonic waves respectively emitted by the plurality of ultrasonic emission units 20 is greater than a predetermined value. As the predetermined value, any value between 10 and 30 Hz can be adopted. According to another embodiment, the beauty device 1 can measure the sound with a microphone during the operation of the ultrasonic emission unit 20, and adjust the frequencies of the plurality of ultrasonic emission units 20, for example, by adjusting the variable resistor in the drive circuit. According to still another embodiment, the beauty device 1 can include a hum absorption material that absorbs or attenuates the hum with a frequency of several Hz. The beauty device 1 can also include earplugs or a housing that absorbs or attenuates the hum with a frequency of several Hz.

[0068] Furthermore, since high-frequency sound waves have high directivity, in the ultrasonic wave emitting unit 20, sometimes the sound waves only reach a limited range. Therefore, the beauty device 1 can also be provided with masks, reflector plates (especially metal plates with high sound reflectivity), tuning plates, glass wool, etc. at multiple positions in order to scatter and diffuse the ultrasonic waves. In addition, the beauty device 1 can also prepare multiple resonant vibrating plates before the ultrasonic wave emitting unit 20.

[0069] In addition, since the beauty device 1 is sometimes used in a state where cosmetics are applied, waterproofing is required in the ultrasonic wave emitting unit 20. If the ultrasonic wave emitting unit 20 is covered with a waterproof member for waterproofing, sometimes the sound pressure will be impaired. Therefore, the beauty device 1 covers the ultrasonic wave emitting unit 20 with an elastic raw material having waterproof properties that has less influence on the propagation of ultrasonic waves. Specifically, it is preferable to use an elastic raw material having a modulus of elasticity between 0.1 MPa and 50 MPa and an ultrasonic attenuation rate between 0.1 and 0.3. For example, it is preferable to use silicone rubber or polyurethane rubber. In addition, the ultrasonic wave emitting unit 20 can also be arranged in a place that is not easily wetted, and waterproofing can be achieved by reflecting ultrasonic waves.

[0070] [Light irradiation unit 30]

[0071] The light irradiation unit 30 irradiates light toward the user's face when the beauty device 1 is worn by the user. The beauty device 1 has a plurality of light irradiation units 30 on the inner surface 10B of the cover 10. The number of the light irradiation units 30 is, for example, from 1 to 500.

[0072] The light irradiation unit 30 has, for example, a light-emitting diode (LED). The light irradiation unit 30 has, for example, a laser diode (LD).

[0073] The light irradiation unit 30 can directly irradiate the user with light from the light-emitting element, or can irradiate the user with light from the light-emitting element via an optical member. The light irradiation unit 30 is preferably, for example, of a general waterproof specification.

[0074] The light irradiation unit 30 irradiates visible light, for example. The range of the visible light irradiated by the light irradiation unit 30 is, for example, in the range of a wavelength of 380 nm to 800 nm, especially in the range of 600 nm to 800 nm.

[0075] In addition, the light irradiation unit 30 irradiates near-infrared light, for example. The range of the near-infrared light irradiated by the light irradiation unit 30 is, for example, in the range of a wavelength of 800 nm to 1 mm, especially in the range of 800 nm to 2.5 μm.

[0076] In addition, as the light irradiation unit 30, a light irradiation unit that irradiates visible light and a light irradiation unit that irradiates near-infrared light may be mixed and present. In addition, light irradiation units having different wavelengths in visible light and near-infrared light may be mixed and present.

[0077] The light irradiation unit 30 irradiates light in the range of, for example, 50 mW / cm² to 500 mW / cm² toward the face. The light irradiation unit 30 may also be, for example, at a distance in the range of 5 mm to 50 mm from the face.

[0078] The range of light irradiated by one light irradiation unit 30 can be, for example, in the range of 1 mm to 10 mm in diameter in the case of condensing light. In addition, the range of light irradiated by one light irradiation unit 30 can be, for example, in the range of 10 mm to 300 mm in diameter in the case of diffusing light.

[0079] The light irradiation unit 30 may also include a light-emitting light source and a second irradiation range adjustment unit for adjusting the irradiation range of the light emitted from the light source. The second irradiation range adjustment unit may have one or more optical members. Examples of the second irradiation range adjustment unit include (a) a reflecting mirror or a zoom mirror, (b) a lens or a zoom lens, (c) an actuator for adjusting (i) the distance between the output end of the light source and the inner surface 10B of the cover 10, and / or (ii) the posture of the light source, etc. Examples of the zoom mirror include a mirror array (including a micromirror array). Examples of the zoom lens include a lens array (including a microlens array), a liquid lens, a Fresnel lens, etc.

[0080] The light irradiation unit 30 irradiates light, for example, to a part (sometimes referred to as a second part) including at least any one of the forehead, temples, cheeks, nose, nasolabial folds, facial lines, eyelids, and neck.

The light irradiation unit 30 may be configured to be detachable and attachable at a predetermined position in the cover 10. The light irradiation unit 30 may be configured to be rotatable relative to the cover 10.

[0082] [Protective member 40]

[0083] The protective member 40 protects the user's eyes from the effects of ultrasonic waves and light. The protective member 40 is provided to surround the user's eyes when the beauty device 1 is worn by the user. The protective member 40 is provided on the inner surface 10B.

By the ultrasonic waves being reflected by the protection member 40, leakage of ultrasonic waves to the outside can be prevented. In addition, by the ultrasonic waves being reflected by the protection member 40, the ultrasonic waves can be returned to the user side and effectively utilized.

[0088] The attenuation rate of ultrasonic waves in the protection member 40 can be 5% or more, 10% or more, 20% or more, 30% or more, 40% or more, 50% or more, 60% or more, 70% or more, 80% or more, 90% or more, 95% or more.

The above attenuation rate can be any value from 5% or more and 100% or less, any value from 10% or more and 100% or less, any value from 5% or more and 95% or less, any value from 10% or more and 90% or less, any value from 20% or more and 60% or less. Thereby, the protected part can be protected from the influence of ultrasonic waves.

[0089] The attenuation rate of ultrasonic waves in the protective member 40 is preferably 30% or more, more preferably 50% or more, and particularly preferably 60% or more. Thereby, the protected part can be sufficiently protected.

[0090] The reflectivity of ultrasonic waves in the protective member 40 can be greater than or equal to 5%, greater than or equal to 10%, greater than or equal to 20%, greater than or equal to 30%, greater than or equal to 40%, greater than or equal to 50%, greater than or equal to 60%, greater than or equal to 70%, greater than or equal to 80%, greater than or equal to 90%, greater than or equal to 95%.

Therefore, the protected part can be protected from ultrasonic wave irradiation.

[0091] The reflectivity of ultrasonic waves in the protective member 40 is preferably 30% or more, more preferably 50% or more, and particularly preferably 60% or more. Thereby, the protected part can be sufficiently protected.

[0092] The transmittance of light in the protective member 40 can be 80% or less, can be 70% or less, can be 60% or less, can be 50% or less, can be 40% or less, can be 30% or less, can be 20% or less, can be 10% or less, can be 5% or less.

[0093] The transmittance of light in the protective member 40 is preferably 40% or less, more preferably 20% or less, and particularly preferably 10% or less. Thereby, the protected part can be sufficiently protected.

[0094] In addition, in the protective member 40, when the contact portion 41 is formed of, for example, rubber or resin, a material with an intrinsic acoustic impedance of 5×10 6 Pascal seconds per cubic meter or more can also be used inside. In other words, in the protective member 40, a part that does not contact the user's face (non-contact portion, such as the inside of the contact portion 41) can also be formed using a material with an intrinsic acoustic impedance of 5×10 6 Pascal seconds per cubic meter or more.

[0095] In addition, at least one of the ultrasonic wave emitting portion 20 and the light irradiation portion 30 can also be arranged in the cylindrical portion 42.

[0096] Next, the operation of the beauty device according to the first embodiment will be described. Figure 5 FIG. Figure 5 is a diagram showing the functional configuration of a beauty device 1 as an example of the beauty device according to the first embodiment.

[0097] The beauty device 1 includes a control unit 100 that controls and drives an ultrasonic emission unit 20 and a light irradiation unit 30. The control unit 100 includes an overall control unit 110, an ultrasonic drive unit 120, and a light drive unit 130.

[0098] The overall control unit 110 controls the entire beauty device 1. The overall control unit 110 controls the ultrasonic drive unit 120 and the light drive unit 130. The overall control unit 110 is, for example, a computer including a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory). The overall control unit 110 executes processing, for example, by reading a program stored in the ROM into the RAM and executing it by the CPU.

[0099] Based on the control of the overall control unit 110, the ultrasonic drive unit 120 drives the ultrasonic emission unit 20 to emit ultrasonic waves from the ultrasonic emission unit 20. For example, when an instruction to emit ultrasonic waves is issued from the overall control unit 110, the ultrasonic drive unit 120 generates, for example, a drive signal having a given voltage waveform for driving the ultrasonic generation element included in the ultrasonic emission unit 20. Then, the ultrasonic drive unit 120 supplies the generated drive signal to the ultrasonic emission unit 20. The ultrasonic emission unit 20 supplied with the drive signal emits ultrasonic waves.

[0100] The ultrasonic drive unit 120 drives a plurality of ultrasonic emission units 20. The ultrasonic drive unit 120 can also switch the ultrasonic emission unit 20 to which the drive signal is supplied, for example, by a switching circuit such as a demultiplexer.

[0101] Based on the control of the overall control unit 110, the light drive unit 130 drives the light irradiation unit 30 to irradiate light (visible light or near-infrared light) from the light irradiation unit 30. For example, when an instruction to irradiate light is issued from the overall control unit 110, the light drive unit 130 generates, for example, a drive signal having a given voltage waveform for driving the light-emitting element included in the light irradiation unit 30. Then, the light drive unit 130 supplies the generated drive signal to the light irradiation unit 30. The light irradiation unit 30 supplied with the drive signal irradiates light.

[0102] The light drive unit 130 drives a plurality of light irradiation units 30. The light drive unit 130 can also switch the light irradiation unit 30 to which the drive signal is supplied, for example, by a switching circuit such as a demultiplexer.

[0103] The overall control unit 110 can be controlled to continuously output ultrasonic waves and light simultaneously, or can be controlled to alternately output ultrasonic waves and light. For example, the overall control unit 110 can be controlled to alternately output in the order of light, ultrasonic wave, light, ultrasonic wave, or can be controlled to alternately output in the order of ultrasonic wave, light, ultrasonic wave, light. Additionally, for example, the overall control unit 110 can also be controlled to stop output after alternately outputting in the order of light, ultrasonic wave, light, ultrasonic wave, and then alternately output again in the order of light, ultrasonic wave, light, ultrasonic wave. Similarly, the overall control unit 110 can also be controlled to stop output after alternately outputting in the order of ultrasonic wave, light, ultrasonic wave, light, and then alternately output again in the order of ultrasonic wave, light, ultrasonic wave, light.

[0104] In addition, the overall control unit 110 can also be controlled to repeatedly output ultrasonic waves and light respectively while changing the intensities of the ultrasonic waves and light. For example, the overall control unit 110 can be controlled to alternately output in the order of strong light, strong ultrasonic wave, weak light, weak ultrasonic wave, or can be controlled to alternately output in the order of weak light, weak ultrasonic wave, strong light, strong ultrasonic wave.

[0105] Furthermore, the overall control unit 110 can also repeatedly output ultrasonic waves and light respectively while changing the types of light irradiated. For example, the overall control unit 110 can be controlled to alternately output in the order of visible light, ultrasonic wave, near-infrared light, ultrasonic wave. Additionally, furthermore, the overall control unit 110 can also change the type of light irradiated while changing the intensity of the ultrasonic wave. For example, the overall control unit 110 can be controlled to alternately output in the order of visible light, strong ultrasonic wave, near-infrared light, weak ultrasonic wave, or can be controlled to alternately output in the order of visible light, weak ultrasonic wave, near-infrared light, strong ultrasonic wave.

[0106] In addition, the overall control unit 110 can also be controlled by alternately setting the output period (emission or irradiation) of each of the ultrasonic wave and light output, and the pause period of stopping output. Additionally, the overall control unit 110 can be controlled such that the output period and the pause period are of the same length, or can be controlled such that the output period is longer than the pause period, or can also be controlled such that the output period is shorter than the pause period.

[0107] Furthermore, the overall control unit 110 can be controlled such that the output period in the ultrasonic wave is of the same length as the output period in the light, or can be controlled to be of different lengths. Similarly, it can be controlled such that the pause period in the ultrasonic wave is of the same length as the pause period in the light, or can be controlled to be of different lengths.

[0108] In addition, the overall control unit 110 can be controlled such that the ratio of the output period to the pause period in the ultrasonic wave is the same as that in the light, or can be controlled to be different.

[0109] Furthermore, the overall control unit 110 can also have multiple modes. For example, the overall control unit 110 can have a "barrier function recovery mode", a "melanin pigmentation / darkening mode", a "beauty mode", a "sleep aid mode", a "wake-up mode", etc.

[0110] The "barrier function recovery mode" is, for example, a mode for restoring the barrier function of the skin. The overall control unit 110 outputs ultrasonic waves for control, for example.

[0111] The "melanin pigmentation / darkening mode" is, for example, a mode for improving skin melanin pigmentation and darkening. The overall control unit 110 outputs infrared light for control, for example.

[0112] The "beauty mode" is, for example, a mode for improving moisture, elasticity, and luster. The overall control unit 110 outputs visible light, especially red light, for control, for example.

[0113] The "sleep aid mode" is, for example, a mode for operating the beauty device 1 when the user is sleeping. The overall control unit 110 controls in a manner that suppresses the intensity of ultrasonic waves and light so as not to give the user excessive stimulation.

[0114] The "wake-up mode" is, for example, a mode for operating the beauty device 1 when waking up a sleeping user. The overall control unit 110 controls in a manner that increases the intensity of ultrasonic waves and light so that the user wakes up. [[ID=2,0]]

[0115] In addition, the overall control unit 110 can be controlled, for example, to change whether it is a maintenance mode, a stop mode, or a change mode through buttons or the like. Furthermore, the overall control unit 110 can change the parameters in each mode according to the diagnosis result and can also perform fine-tuning.

[0116] In addition, when using the beauty device 1, since the field of vision is restricted, it is sometimes difficult to operate the operation unit such as a controller. In addition, if a remote controller or the like is newly equipped, the cost sometimes increases, and in addition, the management sometimes becomes complicated. Therefore, the beauty device 1 can also enable gesture input through the face. For example, the beauty device 1 can detect the movement of the face through an acceleration sensor to turn the power on / off or switch the mode. In addition, the beauty device 1 can also turn the power on / off or switch the mode by detecting a tap on the mask.

[0117] According to the beauty device according to the first embodiment, in a beauty device that emits ultrasonic waves to a user and irradiates light to the user, the eyes can be protected and ultrasonic wave leakage can be prevented.

[0118] In the present embodiment, the inner surface 10B of the cover member 10 may be configured such that at least one of ultrasonic waves and light undergoes retroreflection. For example, the so-called retroreflection of light means that the reflected light returns in a direction substantially along the optical path of the incident light. The same applies to the retroreflection of ultrasonic waves. Thereby, the irradiation amount of ultrasonic waves and / or light can be precisely controlled. In addition, ultrasonic waves and / or light can be irradiated efficiently.

[0119] For example, in the beauty device 1, on the inner surface 10B of the cover member 10, a retroreflective material is pasted on at least a part of the portion where neither the ultrasonic wave emitting portion 20 nor the light irradiation portion 30 is provided. As the retroreflective material, a retroreflective sheet can be exemplified. The retroreflective material can be, for example, a retroreflective material having a corner cube prism or a corner mirror, or can be a retroreflective material having glass beads.

[0120] In addition, the beauty device according to the first embodiment can also, for example, form the inner surface of the cover member with a material having an acoustic impedance of 5×10 6 Pascal seconds per cubic meter or more so that ultrasonic waves are reflected on the inner surface of the cover member.

[0121] In the example of the beauty device 1 described above, the beauty device 1 is fixed by joining the strap 11 and the strap 12 at the back of the head, but in the beauty device according to the first embodiment, the fixing method is not limited to the above example. For example, the beauty device according to the first embodiment can also be fixed by hanging on the ears. In addition, for example, the beauty device according to the first embodiment can also be fixed by hanging on the nose.

[0122] For example, when the beauty device according to the first embodiment is hung on the ears, the beauty device according to the first embodiment can also stimulate the ears. For example, the beauty device according to the first embodiment can also apply electrical stimulation, acoustic stimulation, thermal stimulation, and / or vibration stimulation to the ears.

[0123] For example, the beauty device 1 according to the first embodiment includes a "sedation mode" for sedating the autonomic nerves. When the overall control unit 110 receives a signal indicating that the user has selected the sedation mode, the overall control unit 110 can determine to output a sound in the audible range (for example, 20 to 40 Hz). The overall control unit 110 can determine to output a predetermined type of sound. As the predetermined type of sound, music content, ASMR content, etc. can be exemplified. The overall control unit 110 can obtain these contents from the user's terminal or can obtain these contents from a server via a communication line. The overall control unit 110 can determine to output a 20 to 40 Hz sound at a rhythm of 50 to 100 bpm. Thereby, the user can be relaxed.

[0124] The overall control unit 110 can control the ultrasonic emission unit 20 so that the ultrasonic emission unit 20 of the beauty device 1 is used as a parametric speaker, and the sound in the audible range is output from the ultrasonic emission unit 20. When the beauty device 1 is equipped with a speaker, the overall control unit 110 can control the speaker to output the above-mentioned sound.

[0125] The overall control unit 110 can also use the ultrasonic emission unit 20 or the speaker as a message transmission unit. Examples of messages include the method of a specific action, etc. Thus, for example, the user can understand the method of a specific gymnastics.

[0126] In one embodiment, the beauty device 1 can be equipped with a first vibration element for vibrating the ear. In this case, the overall control unit 110 can control the first vibration element according to the above-mentioned sound. In another embodiment, the beauty device 1 can be equipped with a second vibration element for vibrating the cover 10. In this case, the overall control unit 110 can control the second vibration element so that the cover 10 vibrates according to the above-mentioned sound.

[0127] The overall control unit 110 can use the first vibration element or the second vibration element to support or train the user's specific actions. Examples of specific actions include breathing, etc. Thus, the beauty device 1 can prompt the user of the timing of breathing through vibration. As a result, the user can train the breathing method.

[0128] For example, when the beauty device according to the first embodiment is hung on the nose, the beauty device according to the first embodiment can also stimulate the nose. For example, the beauty device according to the first embodiment can warm the nose or remove blackheads through iontophoresis.

[0129] 《Second Embodiment》

[0130] The beauty device according to the second embodiment will be described. The beauty device according to the second embodiment is equipped with a cover having a two-layer structure. And, the beauty device according to the second embodiment has an ultrasonic emission unit in one layer of the two-layer structure and a light irradiation unit in the other layer of the two-layer structure.

[0131] The details of the beauty device according to the second embodiment will be described with reference to the drawings. Figure 6 It is a perspective view for explaining a cover 210 which is an example of the cover of the beauty device according to the second embodiment. Figure 7 It is a rear view for explaining a cover 210 which is an example of the cover of the beauty device according to the second embodiment. Additionally, Figure 6 and Figure 7 It is a view showing a part of the cover 210.

[0132] The cover member 210 includes a substrate 210a and a substrate 210b. In other words, the cover member 210 has a two-layer structure including the substrate 210a and the substrate 210b.

[0133] The substrate 210a is the substrate disposed on the user side. The substrate 210a holds the ultrasonic emission unit 20. The substrate 210a has an opening 210a1 penetrating the substrate 210a. The opening 210a1 is provided corresponding to the light irradiation unit 30 disposed on the substrate 210b. The light emitted from the light irradiation unit 30 is irradiated toward the user from the opening 210a1.

[0134] The substrate 210b is the substrate disposed on the opposite side of the user with respect to the substrate 210a. The substrate 210b holds the light irradiation unit 30.

[0135] According to the beauty device according to the second embodiment, it is possible to increase the mounting density of each of the ultrasonic emission unit and the light irradiation unit, and increase the number of ultrasonic emission units and light irradiation units that can be mounted on the cover member.

[0136] In addition, in the above example, the ultrasonic emission unit 20 is provided on the substrate 210a and the light irradiation unit 30 is provided on the substrate 210b, but the light irradiation unit 30 may be provided on the substrate 210a and the ultrasonic emission unit 20 may be provided on the substrate 210b.

[0137] 《Third Embodiment》

[0138] A beauty device according to the third embodiment will be described. The beauty device according to the third embodiment divides the cover member into modules.

[0139] The details of the beauty device according to the third embodiment will be described with reference to the drawings. Figure 8 It is a front view for describing a beauty device 301 as an example of the beauty device according to the third embodiment.

[0140] The beauty device 301 includes a cover member 310. The cover member 310 includes a main body portion 311, an upper module 312, and a lower module 313. The upper module 312 and the lower module 313 are respectively detachably connected to the main body portion 311.

[0141] The main body portion 311 is disposed at a position corresponding to the periphery of the user's eyes. On the inner surface on the user side, the main body portion 311 is provided with an ultrasonic emission unit and a light irradiation unit. The main body portion 311 cares for the periphery of the user's eyes by ultrasonic waves and light. The main body portion 311 is fixed to the user's head. For example, when a battery is mounted on the main body portion 311, it is preferable that the battery is disposed at the rear of the head such that the center of gravity is located at the center of the head.

[0142] The main body portion 311 may also be provided with a massage module (not shown) for physically massaging a part of the user's body. The massage module may be configured such that when the beauty device 1 is worn by the user, the massage module is located at the back of the user's head. The massage module may have a vibration device for transmitting vibration to the user.

[0143] The upper module 312 is provided near the user's forehead. The upper module 312 is connected to the main body 311 in an interchangeable manner. The inner surface of the upper module 312 on the user side is provided with an ultrasonic emission portion and a light irradiation portion. The upper module 312 cares for the area around the user's forehead through ultrasonic waves and light. The upper module 312 is supplied with power from the main body portion 311, for example. The upper module 312 prepares a variety of modules with different specifications so that optimal care can be performed according to the state or characteristics of the user's skin.

[0144] The lower module 313 is provided near the user's cheeks and mouth. The lower module 313 is connected to the main body portion 311 in an interchangeable manner. The inner surface of the lower module 313 on the user side is provided with an ultrasonic emission portion and a light irradiation portion. The lower module 313 cares for the area around the user's cheeks and mouth through ultrasonic waves and light. The lower module 313 is supplied with power from the main body portion 311, for example. The lower module 313 prepares a variety of modules with different specifications so that optimal care can be performed according to the state or characteristics of the user's skin.

[0145] For example, skin problems vary from person to person and from area to area. Therefore, the content to be cared for varies from person to person and from area to area. In a beauty device, it is difficult to provide functions in a way that covers all the items to be cared for for various people and areas in terms of size and cost.

[0146] Therefore, the beauty device according to the third embodiment can be easily replaced with a module by modularization. According to the beauty device according to the third embodiment, by replacing the module, the energy required for care can be transmitted to the required place.

[0147] <Modification example>

[0148] In the present embodiment, the beauty device 1 is a mask-type wearable device as an example, and the details of the beauty device have been described. However, the beauty device 1 is not limited to the present embodiment. In another embodiment, the beauty device 1 may be a head-mounted wearable device, or a neck-band type or shoulder-band type wearable device. The head-mounted wearable device is in physical contact with at least one part of the user's head. As described above, examples of the parts included in the head are the face, the head, and the neck. The neck-band type or shoulder-band type wearable device is in physical contact with the user's neck or shoulder.

[0149] For example, a neck-type beauty device worn around the neck can care for the skin of the face, chin, and neck without impairing the user's field of vision. The neck-type beauty device outputs ultrasonic waves or light as non-contact energy from the neck, which does not obstruct a person's field of vision. In addition, when outputting ultrasonic waves or light, for example, the output element can also be arranged on a base equipped with one or more hinge mechanisms to change the irradiation direction. In addition, a reflective element capable of changing the direction can be used to reflect the energy (ultrasonic waves or light) to change the irradiation direction. Furthermore, the entire face can be irradiated while automatically changing the intensity according to the irradiation angle and distance. In addition, for example, when there are irradiation taboo areas such as the eyes, irradiation can be automatically avoided.

[0150] In addition, in the above example, the neck-type is described, but as long as it is within the range that does not obstruct a person's field of vision, for example, at a position more than 10 cm above and below the eyeball as the starting point, a structure for irradiating energy (ultrasonic waves or light) can be provided.

[0151] In addition, in the case of the neck-type, for example, physical massage can be performed on the neck and shoulders, or heating can be performed on them.

[0152] In the present embodiment, the case where the mesh member 10m1 and / or the mesh member 10n1 is arranged at the opening of the beauty device 1 is taken as an example to describe the beauty device in detail. However, the shape of the member that at least partially covers the opening (sometimes referred to as a covering member) is not limited to a mesh. In other embodiments, the shape of the covering member can be a blanked plate shape, a lattice shape, a sponge shape, or a porous body. The covering member can have a hollow structure. The covering member has a hollow structure such as a conical shape, a hemispherical shape, a semi-ellipsoidal shape, a tray shape, or a box shape, for example. The mesh member 10m1 can be an example of the covering member. The mesh member 10n1 can be an example of the covering member.

[0153] In the present embodiment, the case where the overall control unit 110 controls the beauty device 1 based on the user's instruction is taken as an example to illustrate the details of the beauty device 1. However, the overall control unit 110 is not limited to this embodiment. In other embodiments, the overall control unit 110 can also control the beauty device 1 based on an instruction from an external information processing device. Examples of the external information processing device include an information processing device used by the user (for example, a portable terminal), a server, etc. Examples of the content of the above instruction include the type of the operation mode of the beauty device 1, the intensity of the operation, the duration of the operation, the type of the actually operating module among the energy emission modules mounted on the beauty device 1, etc. Examples of the energy emission module include an RF module, an EMS module, an interference wave EMS module, an ultrasonic wave emission module, a light emission module, etc.

[0154] The above-mentioned external information processing device can output the above-mentioned instructions based on an image including the user's face as a subject and the consultation results from the user or the beautician. The overall control unit 110 can also output information such as the operation history, action history, and user ID of the beauty device 1 to the above-mentioned external information processing device.

[0155] In the present embodiment, the case where the beauty device 1 includes modules that emit ultrasonic waves and light is taken as an example to explain the details of the beauty device 1. However, the beauty device 1 is not limited to this embodiment. In other embodiments, the beauty device 1 may include at least one of an RF module, an EMS (Electrical Muscle Stimulation) module, an interference wave EMS module, an ultrasonic wave emission module, and a light emission module.

[0156] [Interference wave EMS module]

[0157] For example, when the beauty device 1 includes an interference wave EMS module, the interference wave EMS module emits two or more carriers with different electrical characteristics. As the electrical characteristics, at least one of voltage (sometimes referred to as amplitude), frequency, and phase can be exemplified. The interference wave EMS module includes three or more electrodes and a carrier output unit that outputs the above-mentioned two or more carriers to the three or more electrodes.

[0158] The carrier output unit, for example, (i) applies a first signal for generating a first carrier having a first electrical characteristic to any two of the three or more electrodes; (ii) applies a second signal for generating a second carrier having a second electrical characteristic to one or two of the remaining electrodes. Thus, the carriers are output to the user's body surface and / or inside the body. The carrier output unit can apply the first signal and the second signal to each electrode according to an instruction from the overall control unit 110.

[0159] The carrier output unit can also apply a third signal for generating a third carrier having a third electrical characteristic to one or two of the electrodes to which the first signal and the second signal are not applied. When the interference wave EMS module includes four or more electrodes, the carrier output unit can also not apply a signal to at least one electrode. At least one of the voltage, frequency, and phase of the first electrical characteristic is different from that of the second electrical characteristic. At least one of the voltage, frequency, and phase of the first electrical characteristic is different from that of the third electrical characteristic. At least one of the voltage, frequency, and phase of the second electrical characteristic is different from that of the third electrical characteristic.

[0160] The carrier output unit may, for example, also apply a first signal to a plurality of electrode pairs to generate a plurality of first carriers. Similarly, the carrier output unit may, for example, also apply a second signal to a plurality of electrode pairs to generate a plurality of second carriers. The carrier output unit may, for example, also apply a third signal to a plurality of electrode pairs to generate a plurality of third carriers.

[0161] For example, in the case where the interference wave EMS module includes three electrodes (electrode A, electrode B, and electrode C), the above three electrodes are disposed on the body surface of the user. Thereby, a first circuit including (i) the carrier output unit, electrode A, a part of the user's body, and electrode B, and a second circuit including (ii) the carrier output unit, electrode C, a part of the user's body, and electrode B are formed. The carrier output unit applies a first signal to electrode A and electrode B. Thereby, a first carrier is generated on the body surface of the user and / or in the region between electrode A and electrode B within the body. Similarly, the carrier output unit applies a second signal to electrode C and electrode B. Thereby, a second carrier is generated on the body surface of the user and / or in the region between electrode C and electrode B within the body. By the interference of the first carrier and the second carrier on the body surface of the user and / or within the body, an interference wave corresponding to the difference in electrical characteristics between the first carrier and the second carrier is generated.

[0162] For example, in the case where the interference wave EMS module includes four electrodes (electrode A, electrode B, electrode C, and electrode D), the above four electrodes are disposed on the body surface of the user. Thereby, a first circuit including (i) the carrier output unit, electrode A, a part of the user's body, and electrode B, and a second circuit including (ii) the carrier output unit, electrode C, a part of the user's body, and electrode D are formed. The carrier output unit applies a first signal to electrode A and electrode B. Thereby, a first carrier is generated on the body surface of the user and / or in the region between electrode A and electrode B within the body. Similarly, the carrier output unit applies a second signal to electrode C and electrode D. Thereby, a second carrier is generated on the body surface of the user and / or in the region between electrode C and electrode D within the body. By the interference of the first carrier and the second carrier on the body surface of the user and / or within the body, an interference wave corresponding to the difference in electrical characteristics between the first carrier and the second carrier is generated.

[0163] [Waveform patterns of the first signal and the second signal]

[0164] (Waveform pattern for repeatedly contracting and relaxing muscles)

[0165] In the present embodiment, the carrier output unit determines the waveform patterns of the first signal and the second signal such that one or more interference waves having an amplitude greater than a first threshold are generated on and / or inside the user's body surface (sometimes referred to as the on-period), and the period during which no interference wave having an amplitude greater than the first threshold is generated (sometimes referred to as the off-period) repeat. The first threshold is determined, for example, such that the peak value of the amplitude of the interference wave generated during the off-period is 10% or less of the peak value of the amplitude of the interference wave generated during the on-period.

[0166] The technical significance of the on-period and the off-period is as follows. In the present embodiment, for the purpose of simplifying the description, the case where a section (pattern section) composed of a single on-period and a single off-period is generated multiple times is taken as an example to illustrate the technical significance of the on-period and the off-period.

[0167] According to the present embodiment, for example, the user's muscle contracts during the on-period and relaxes during the off-period. By appropriately adjusting the length of the on-period and the length of the off-period, through the pump effect of the muscle, improvement in blood flow, removal of metabolites, improvement in body fluid circulation, restoration or revival or regeneration of capillary function, etc. can be anticipated. As a result, (i) elimination of edema, (ii) improvement in skin dullness, elasticity, and / or metabolism, etc. can be expected. By eliminating edema, a small face effect can also be expected. In addition, by repeating the contraction and relaxation of the muscle, effects such as muscle hypertrophy and fascia alignment can be anticipated. As a result, effects such as improvement in facial relaxation and elevation of the facial shape can be expected.

[0168] The pattern section may include at least one on-period and at least one off-period. The pattern section includes, for example, n on-periods and n off-periods. Here, n is an integer of 1 or more. The carrier output unit may determine the waveform patterns of the first signal and the second signal such that the same type of pattern section repeats, or may determine the waveform patterns of the first signal and the second signal such that multiple different types of pattern sections are generated.

[0169] In the present embodiment, the carrier output unit determines the waveform patterns of the first signal and the second signal such that the length of the period during which muscle contraction occurs (sometimes referred to as the contraction period) in the pattern period is shorter than the length of the period during which the muscle is not contracting or is relaxed (sometimes referred to as the relaxation period). By starting muscle contraction in a state where the muscle is fully relaxed, the muscle can be stimulated within the maximum movable range of the muscle. Therefore, when the length of the contraction period is shorter than the length of the relaxation period, an increase in muscle hypertrophy effect can be expected compared to the case where the length of the contraction period is longer than the length of the relaxation period. As a result, effects such as improvement of facial sagging and enhancement of facial shape can be expected. In addition, in this case, deceleration and / or backflow of blood and / or body fluids can be suppressed. Thereby, an increase in the pumping effect of the muscle can be expected. As a result, (i) elimination of edema, (ii) improvement of skin dullness, elasticity, and / or metabolism, etc. can be expected. By eliminating edema, a small face effect can also be expected.

[0170] In one embodiment, a first pattern period including a first on-period, a first off-period, a second on-period, and a second off-period in sequence is repeated. In the first pattern period, the length of the second off-period can be longer than the length of the first off-period. Thereby, the length of the contraction period is shorter than the length of the relaxation period.

[0171] In another embodiment, the first pattern period includes a first on-period, a first off-period, a second on-period, and a second off-period in sequence, and a second pattern period immediately following one or more first pattern periods includes a first on-period, a first off-period, a second on-period, a second off-period, a third on-period, and a third off-period in sequence. In the first pattern period, the length of the second off-period can be longer than the length of the first off-period. In the second pattern period, the length of the third off-period can also be longer than the lengths of the first off-period and the second off-period. Thereby, the length of the contraction period is shorter than the length of the relaxation period.

[0172] In yet another embodiment, a first pattern period including a first off-period, a first on-period, a second off-period, and a second on-period in sequence is repeated. In the first pattern period, the length of the first off-period can be longer than the length of the second off-period. Thereby, the length of the contraction period is shorter than the length of the relaxation period.

[0173] In yet another embodiment, the first pattern interval sequentially includes a first off period, a first on period, a second off period, and a second on period, and the second pattern interval immediately following one or more first pattern intervals sequentially includes a first off period, a first on period, a second off period, a second on period, a third off period, and a third on period. In the first pattern interval, the length of the first off period may be longer than the length of the second off period. In the second pattern interval, the length of the first off period may also be longer than the lengths of the second off period and the third off period.

[0174] In the present embodiment, the carrier output unit may determine the waveform patterns of the first signal and the second signal such that, in each pattern interval of one or more pattern intervals, the ratio of the maximum value of the lengths of one or more off periods included in each pattern interval to the length of each pattern interval exceeds 50%. The above ratio may also be 60% or more, may be 70% or more, may be 75% or more, may be 80% or more, or may be 90% or more. The above ratio is preferably 70% or more, more preferably 75% or more, and particularly preferably 80% or more. Thereby, the above effects can be significantly observed.

[0175] (Amplitude control of interference waves during a single mode period)

[0176] In the present embodiment, the carrier output unit may determine the waveform patterns of the first signal and the second signal such that, when a single pattern interval includes a plurality of on periods and a plurality of off periods, the maximum values of the amplitudes of the interference waves of at least two on periods are different. The carrier output unit may also determine the waveform patterns of the first signal and the second signal such that, when a single pattern interval includes a plurality of on periods and a plurality of off periods, the maximum values of the amplitudes of the interference waves of each on period are different. In the amplitude control of the interference waves, the carrier output unit (i) may determine to sharply increase or sharply decrease the amplitude of the interference wave, (ii) may also determine to gradually increase or sharply decrease the amplitude of the interference wave, (iii) may also determine to sharply increase or gradually decrease the amplitude of the interference wave, or (iv) may also determine to gradually increase or gradually decrease the amplitude of the interference wave.

[0177] In the above various embodiments, the details of the carrier output unit have been described by taking the case where the carrier output unit determines various controls as an example. However, the carrier output unit is not limited to these embodiments. In other embodiments, it may also be the overall control unit 110 that determines various controls, and the carrier output unit operates based on an instruction from the overall control unit 110.

[0178] In one embodiment, the carrier output unit determines the waveform patterns of the first signal and the second signal such that the maximum value of the amplitude of the interference wave included in the last on-period in terms of time among the multiple on-periods included in a single pattern period is greater than the maximum value of the amplitude of the interference wave included in other on-periods. Thereby, the amplitude of the interference wave can be gradually increased. In this case, since the load applied to the muscle gradually increases, compared with the case where the load applied to the muscle rapidly increases, the variation in the muscle contraction speed can be suppressed. As a result, the maximum muscle strength can be effectively increased.

[0179] In another embodiment, the waveform patterns of the first signal and the second signal are determined such that the maximum value of the amplitude of the interference wave included in a specific on-period is less than the maximum value of the amplitude of the interference wave included in at least one on-period that is later in time than the specific on-period. Thereby, the amplitude of the interference wave can be gradually increased. In this case, since the load applied to the muscle gradually increases, compared with the case where the load applied to the muscle rapidly increases, the variation in the muscle contraction speed can be suppressed. As a result, the maximum muscle strength can be effectively increased.

[0180] When increasing the amplitude of the interference wave, the carrier output unit (i) may determine to increase the voltages of both the first signal and the second signal, (ii) may also determine to increase the voltage of one of the first signal and the second signal while maintaining the voltage of the other, or (iii) may also determine to decrease the voltage of one of the first signal and the second signal and increase the voltage of the other in consideration of the decrease amount. When decreasing the amplitude of the interference wave, the carrier output unit (i) may determine to decrease the voltages of both the first signal and the second signal, (ii) may also determine to decrease the voltage of one of the first signal and the second signal while maintaining the voltage of the other, or (iii) may also determine to increase the voltage of one of the first signal and the second signal and decrease the voltage of the other in consideration of the increase amount.

[0181] The waveform reaching the maximum value of the amplitude of the interference wave can be either linear or non-linear. In addition, before reaching the maximum value of the amplitude of the interference wave, an increase or decrease in amplitude may be included. The waveform reaching the minimum value of the amplitude of the interference wave can be either linear or non-linear. In addition, before reaching the minimum value of the amplitude of the interference wave, an increase or decrease in amplitude may be included.

[0182] (Waveform pattern imparted to the carrier)

[0183] In the present embodiment, the carrier output unit can determine the waveform patterns of the first signal and the second signal in such a manner that the electrical characteristics of at least one of two or more carriers fluctuate. The frequency of the fluctuation is, for example, 10 Hz or less. The frequency of the fluctuation is preferably 1 to 2 Hz, and particularly preferably 1.08 Hz to 1.33 Hz. Thereby, a carrier having a fluctuation similar to that of a human heart rate is generated. As a result, it is possible to expect that the parasympathetic nerve of the user is dominant. The carrier output unit can acquire information related to the heart rate of the user and determine the waveform patterns of the first signal and the second signal in such a manner that the above carrier has a fluctuation substantially the same as that of the heart rate of the user.

[0184] In one embodiment, the carrier output unit determines the waveform patterns of the first signal and the second signal in such a manner that the electrical characteristics of two or more carriers fluctuate and the frequency and / or amplitude of the interference wave fluctuate. In another embodiment, the carrier output unit determines the waveform patterns of the first signal and the second signal in such a manner that the electrical characteristics of two or more carriers fluctuate and the frequency and / or amplitude of the interference wave do not substantially fluctuate. The carrier output unit determines the waveform patterns of the first signal and the second signal, for example, in such a manner that the fluctuations of the electrical characteristics of two or more carriers are substantially the same.

[0185] The plurality of carriers output by the interference wave EMS module have a fluctuation of 10 Hz or less. The plurality of carriers independently have fluctuations. For example, fluctuations may be present while maintaining a constant difference in the frequencies of the plurality of carriers. In addition, the difference in the frequencies of the plurality of carriers may also vary. In this case, due to the fluctuations of the carriers, fluctuations also occur in the interference wave. Particularly preferably, carriers having fluctuations of 1.08 Hz to 1.33 Hz are used. As a result, due to the fluctuations at the same frequency as the heart rate, the parasympathetic nerve is dominant, and a reduction in stress can be expected.

[0186] (Control considering the surface impedance of the skin)

[0187] The overall control unit 110 can determine to output a message for prompting the specification of the base agent to the user in order to control the impedance between the electrodes of the interference wave EMS module and the body surface of the user and control the current path. The output manner of the message is not particularly limited, and examples thereof include text, image, sound, voice, light, vibration, and the like.

[0188] By applying the base agent to the body surface of the user, the impedance between the electrodes of the interference wave EMS module and the body surface of the user can be controlled. Therefore, the current path can be controlled. For example, by using a base agent with low conductivity and high resistance in combination, the current path is concentrated on the body surface. Thereby, an increase in the temperature sensation on the body surface can be expected. By using a base agent with a high dielectric constant in combination, impedance matching between the electrode and the body surface is performed. Thereby, it is possible to expect a reduction in the power loss and unnecessary electrical stimulation generated between the electrode and the body surface.

[0189] [Other features]

[0190] (The control considering the electrode shape)

[0191] The carrier output unit can also control the current distribution according to the electrode shape. For example, when making an electrode pair using triangular electrodes, they are arranged such that the vertices are in the direction where the electrodes face each other.

[0192] (The control method of making the muscle contract and heat using a carrier wave of a frequency not usually used)

[0193] An electrical stimulation method of making the muscle contract at a low frequency while heating. Among the methods of providing warmth, such as current, ultrasonic waves, electromagnetic waves applied non - contact, and heat transfer by contact such as a heater, an intermediate - frequency current with a frequency of 10 kHz to 1 MHz is particularly preferred. The intermediate - frequency current is output from two or more electrodes among three or more electrodes, and a low frequency is generated by making them interfere with each other. In addition, by controlling the temperature rise according to the temperature state of the contracting muscle, the temperature of the muscle is adjusted to a state of +1 to +3 °C relative to the initial temperature of the muscle before treatment, thereby improving the stretchability of the muscle and expecting an improvement in the muscle hypertrophy effect.

[0194] The temperature state of the muscle can be calculated by measuring the temperature of the skin surface using a temperature sensor such as a thermistor. Or, a certain low - frequency stimulation determined by an interference wave caused by EMS or two or more carrier waves can be applied to the muscle, and the temperature state of the muscle can be calculated based on the difference in the contraction movement caused by the temperature state. The methods of measuring the contraction movement include strain sensors, vibration sensors, optical sensors, and cameras. In addition, as an indirect method of measuring the contraction movement, an ultrasonic sensor provided on the electrode can also be used.

[0195] The amplitude and frequency of the carrier wave can be made variable according to the calculated temperature state of the muscle. When the temperature state of the muscle has risen by more than +3 degrees from the initial temperature, methods such as reducing the frequency of the carrier wave or reducing the amplitude, or both methods can be adopted. When the temperature state of the muscle has decreased by more than - 3 degrees from the initial temperature, methods such as increasing the frequency of the carrier wave or increasing the amplitude, or both methods can be adopted.

[0196] During the off period, it is possible to make the frequencies of two or more carriers all the same, or to stop all carriers except one and continue heating the muscle. An effective muscle stimulation method for muscle strength improvement is to repeatedly perform high-added exercises within the maximum range of motion. However, in normal EMS, due to repeated stimulation, fatigue accumulates and its effect gradually decreases over time. In addition, if the muscle fibers are not sufficiently heated, their elasticity is insufficient and they cannot perform exercises within the maximum range of motion. Therefore, it is necessary to increase the temperature of the muscle to soften the muscle fibers and improve elasticity, and to promote blood circulation through heating and timely remove fatigue substances. As a means of heating the muscle, in the case of heat transfer from the epidermis, it takes time until the target muscle is sufficiently heated, and the combination with heat generation using current requires complex adjustment of the output to match the depth of the muscle stimulated with low frequency each time. Considering the above situation, the frequency of the carrier is preferably set to 10 kHz to 1 MHz. Thus, the carrier is set in the frequency band accompanied by heat generation, and low-frequency stimulation can also be obtained through interference waves. In addition, the balance between heat dissipation and heating is good, and the temperature can be controlled between 36 degrees and 40 degrees.

[0197] (Transdermal absorption is carried out while causing muscle contraction using a carrier)

[0198] A stimulation method that simultaneously performs transdermal absorption and muscle contraction. The electrical stimulation uses two or more intermediate frequencies. There are three or more electrodes for outputting the intermediate frequency, and any one or more pairs of them are muscle contraction electrodes arranged for the purpose of muscle contraction, and the other one or more pairs are transdermal absorption electrodes arranged for the purpose of transdermal absorption. Through the interference wave generated by using the intermediate frequencies output from the muscle contraction electrodes and the transdermal absorption electrodes as carriers, muscle contraction can be performed. The transdermal absorption electrodes are arranged such that at least one or more electrodes in a pair are in direct contact with the part where the transdermal absorption effect is desired, such as wrinkles. Through these electrode arrangements, it is possible to perform transdermal absorption while stretching the part where the transdermal absorption effect is desired through muscle contraction. For example, in the case of aiming at wrinkle improvement, by stretching the wrinkle part in the direction perpendicular to the wrinkle, the wrinkle part can be evenly obtained the transdermal absorption effect. Furthermore, by causing muscle contraction while performing transdermal absorption, the active ingredients for transdermal absorption can act over a wide range through the pump effect.

[0199] In addition, there is a method for measuring the stretching state of the transdermal absorption site caused by muscle contraction, and the amplitude of the interference wave can be controlled according to the stretching state. Means for grasping the stretching state include strain sensors, vibration sensors, optical sensors, and cameras. As a method for indirectly measuring the stretching state, an ultrasonic sensor provided on the transdermal absorption electrode can also be used. Especially when the target site is wrinkles, the position, depth, and size of the wrinkles can be measured in advance to guide the contact position of the electrode. The measuring means is image diagnosis, and the position, depth, and size of the wrinkles are analyzed based on the facial image captured by the camera, and coordinates are set for each wrinkle according to the feature points of the face. According to the coordinate information of the wrinkles, one or more pairs of muscle contraction electrodes and one or more pairs of transdermal absorption electrodes can be selected from three or more electrodes in contact with the face. When the electrode is not in contact with the correct position, it can be guided by an external cooperation device such as a device or a smartphone application. Considering the above situation, the frequency of the interference wave is preferably set to 1 Hz to 30 Hz. Thereby, blood and body fluid circulation are continuously promoted, and the active ingredients in the stratum corneum are immediately recovered.

[0200] (Judging the degree of pressure and relieving the pressure state)

[0201] An interference wave generator is provided with a pulse sensor or an electrocardiograph for measuring the heart rate. When the heart rate is 81 bpm or more, it is judged that the user is in a stress state. In particular, when the heart rate is 81 bpm to 99 bpm, the stress level is set to 1, and when the heart rate is 100 bpm or more, the stress level is set to 2. When it is judged that the stress level is 1, a carrier wave including 4 kHz to 5 kHz is output. When it is judged that the stress level is 2, carrier waves including 0.1 kHz to 1 kHz and 4 kHz to 5 kHz are output. The interference wave generated by two or more carrier waves can generate muscle contraction in a rhythm that depicts the same rhythm as the user's normal heart rate when it is judged to be in a stress state, guiding the user's heart rate back to the normal state. When the user's normal heart rate is less than 65 bpm, the frequency of the interference wave is set to 65 bpm, and when the user's normal heart rate is 80 bpm or more, the frequency of the interference wave is set to 80 bpm. When the heart rate returns to the normal state, the generation of the interference wave stops.

[0202] In addition, the stress state can also be judged according to the information obtained by the odor sensor. When the odor sensor detects a change in a specific substance or odor, regardless of the heart rate, it is judged to be stress level 2. For example, the so-called specific substances refer to two compounds composed of dimethyl trisulfide and allyl mercaptan, and the detection site is at the site with sweat glands and apocrine glands. Table 1 shows the relationship between the presence or absence of the detection of the above compounds, the numerical range of the heart rate, and the stress level.

[0203]

Table 1

[0204]

[0205] (Tactile effects other than muscle stimulation, a stimulation method capable of obtaining an effect on the autonomic nerve)

[0206] By setting the frequency of the interference wave to 100 Hz to 1 kHz, effects other than muscle stimulation can be obtained. The sense of stimulation can be controlled by the amplitude and frequency, but can also be controlled by the way of selecting the energized electrodes. The energized electrodes can be selected from three or more, and two or more pairs are selected. For example, when the first electrode pair, the second electrode pair, the third electrode pair, the fourth electrode pair, the fifth electrode pair, and the sixth electrode pair are selected from 12 electrodes, by sequentially switching the energized electrode pairs over time like the first electrode pair and the second electrode pair, the third electrode pair and the fourth electrode pair, the fifth electrode pair and the sixth electrode pair, a feeling like being massaged on the skin surface can be expected.

[0207] (Calibration method)

[0208] Apply a specified voltage to the combined cosmetics and measure the current value to calculate the resistance value of the cosmetics. The resistance value of the cosmetics can be connected to the server via the communication device of the equipment, or an external connection device, or a smartphone application, and refer to the resistance value from the pre-stored cosmetics list, or the user can directly input the resistance value. Apply a specified voltage to the user and measure the current value to calculate the muscle mass and the resistance of the human body. The muscle mass and the human body resistance can also be calculated based on the body information input by the user. The body information also includes the shape type, color, skin troubles and skin problems of the face.

[0209] (Cooling of muscles)

[0210] When the temperature of the target muscle rises above the expected value, heat is absorbed from the epidermis. The means of heat absorption can utilize the heat of vaporization through air cooling, contact with a low-temperature substance, contact with a heat sink, and application of a volatile component.

[0211] [Electrode configuration and device form capable of appropriately applying current to cause muscle contraction regardless of individual differences of the user (such as individual differences in nerves, muscles, lymph, blood vessels, etc.)]

[0212] (Configure multiple electrodes)

[0213] Arbitrarily select two electrodes from more than five electrodes to form an electrode pair. There are more than three electrode pairs, and two or more different carriers are output from each electrode pair. Therefore, by interfering multiple carriers from multiple electrode pairs respectively, multiple interference waves can be generated, and the target muscle can be contracted without moving the device on the skin regardless of the nerve configuration in the body. For example, when selecting an electrode pair composed of two electrodes without repetition from six electrodes, there is a first carrier output from the first electrode pair, and a second carrier output from the second and third electrode pairs. Two interference waves are generated by the interference between the first carrier and the second carrier.

[0214] (Move the electrode)

[0215] In addition, for example, as a means of generating multiple interference waves, the first electrode pair can also be moved and rotated by motor control, thereby changing the positional relationship between the second electrode pair and the third electrode pair and moving the interference wave generation position. It is characterized in that in order to make the first electrode pair easy to move by the motor, the shape of the electrode is preferably such that the contact resistance with the skin is small, and it is preferably substantially dome-shaped.

[0216] (Move the component)

[0217] As a method of adjusting the interference wave generation position outside the electrode configuration, the head of the device provided with the electrodes can also be moved and rotated. It is characterized in that in order to make the head easy to move by the motor provided in the device, the shape of the electrode is preferably such that the contact resistance with the skin is small, and it is preferably substantially dome-shaped.

[0218] (Adjust the rotation of the component)

[0219] In addition, even without using a motor, the user can change the interference wave generation position by adjusting the setting position of the device. For example, the outer shell of the head has a two-layer structure, and the second shell located inside can rotate relative to the first shell located outside. The positional relationship between the first shell and the skin is fixed by the device body, and the second shell can rotate 360 degrees with a scale of 1 degree to 90 degrees through a rotation adjustment mechanism. The rotation center of the second shell is different from the interference wave generation position, and by rotating the second shell, the interference wave generation position can be adjusted on the circumference centered on the rotation center of the second shell. The head can also be disassembled from the device body, and the user can arbitrarily change its fixed position. The connection between the head and the device body is any one of structural fitting, magnetism, and screw fastening.

[0220] In Table 2, an example of the numerical range of the set values of various parameters related to the carrier wave is shown as follows in association with the carrier wave of the interference wave EMS described above. In the case where no special numerical range is set in association with the above-described various embodiments, the carrier wave output unit can determine the waveform patterns of the first signal and the second signal in such a way as to output a carrier wave having the following characteristics.

It is obvious to those skilled in the art that various changes or improvements can be made to the above various embodiments. According to the description of the claims, the embodiments to which such changes or improvements are applied are also included in the technical scope of the present invention. It is obvious to those skilled in the art that, within the scope where there is no technical contradiction, the matters described for a specific embodiment can be applied to other embodiments.

[0243] For example, the specification of the present application discloses the following matters.

[0244] (Item 1)

[0245] An apparatus comprising:

[0246] An ultrasonic wave emitting unit that emits ultrasonic waves;

[0247] A light emitting unit that emits light;

[0248] A support unit that supports the ultrasonic wave emitting unit and the light emitting unit; and
