[0009] Hereinafter, each embodiment of the present disclosure will be described with reference to the accompanying drawings. Note that, in the description of the specification and drawings relating to each embodiment, components having substantially the same or corresponding functional configurations may be designated by the same or corresponding reference numerals, and redundant description may be omitted.

[0010] In the directions of parallel, right-angle, orthogonal, horizontal, vertical, up-down, left-right, front-back, etc., deviations are permitted to the extent that they do not impair the effects of the embodiments. The shape of the corners is not limited to right angles and may be rounded. Parallel, right-angle, orthogonal, horizontal, and vertical may include approximately parallel, approximately right-angle, approximately orthogonal, approximately horizontal, and approximately vertical, respectively.

[0011] For example, "substantially parallel" means that even if two lines or two surfaces are not completely parallel to each other, they can be treated as parallel to each other within the range allowed in manufacturing. As with "substantially parallel," "substantially right angle," "substantially perpendicular," "substantially horizontal," and "substantially vertical" are also intended to fall under the respective terms as long as the relative positional relationship between the two lines or two surfaces is within the range allowed in manufacturing.

[0012] For ease of explanation, the drawings include a virtual three-dimensional coordinate system (XYZ Cartesian coordinate system) consisting of mutually orthogonal X, Y, and Z axes (XYZ axes). For example, for a coordinate axis perpendicular to the plane of the drawing, a black circle within a circle indicates that the coordinate axis faces toward the front of the plane of the drawing. A cross within a circle indicates that the coordinate axis faces away from the plane of the drawing.

[0013] However, this coordinate system is defined for the purpose of explanation and does not limit the posture of the beauty device etc. according to the present embodiment. Also, a view of the object viewed from the +X side along the X-axis in the opposite direction to the X-axis may be referred to as a front view.

[0014] First Embodiment A beauty device according to a first embodiment will be described. The beauty device according to the first embodiment is a wearable beauty device worn by a user. The beauty device according to the first embodiment includes a cover, an ultrasound emission unit, a light irradiation unit, and a protective member. The ultrasound emission unit in the beauty device according to the first embodiment is provided on the inner surface of the cover that faces the user when worn by the user, and emits ultrasound toward a first part of the user. The light irradiation unit in the beauty device according to the first embodiment is provided on the inner surface and irradiates light toward a second part of the user.

[0015] The protective member in the beauty device according to the first embodiment protects the user's eyes from, for example, ultrasound and light. The protective member is provided, for example, on the inner surface of the cover so as to surround the user's eyes when the cover is worn by the user. The protective member in the beauty device according to the first embodiment has a specific acoustic impedance of 5×10 6 Includes materials with a thermal conductivity of pascal-seconds per cubic meter or greater.

[0016] The above-mentioned Patent Documents 1 to 4 do not disclose the idea of protecting a part of a user's body from ultrasound. Patent Document 4 discloses using conductive rubber to prevent light from entering the eyes. However, the absolute value of the difference between the specific acoustic impedance of conductive rubber and the specific acoustic impedance of air is relatively small. Therefore, it is difficult to sufficiently block ultrasound using conductive rubber. In contrast, in this embodiment, at least a portion of the protective member is made of a material or member that satisfies specific conditions regarding reflection and / or attenuation of acoustic impedance. This allows a part of the user's body (sometimes referred to as the protected part) to be protected from ultrasound emitted by a cosmetic device. Furthermore, if at least a portion of the protective member is made of a material or member that satisfies specific conditions regarding light transmittance, the protected part can be protected from ultrasound and light emitted by a cosmetic device.

[0017] An example of the area to be protected is the eyes. The area to be protected may be an area where restrictions on the irradiation of ultrasound and / or light are imposed in a country where the cosmetic device 1 is sold or used.

[0018] A beauty device according to a first embodiment will be described with reference to the drawings. FIG. 1 is a perspective view showing an overview of a beauty device 1, which is an example of a beauty device according to the first embodiment. FIG. 2 is a front view showing an overview of a beauty device 1, which is an example of a beauty device according to the first embodiment. FIG. 3 is a rear view showing an overview of a beauty device 1, which is an example of a beauty device according to the first embodiment. FIG. 4 is a perspective view showing an overview of a beauty device 1, which is an example of a beauty device according to the first embodiment.

[0019] In this embodiment, the beauty device 1 is a wearable beauty device worn by a user. The beauty device 1 is configured to be wearable, for example, on a part of the user's body. This allows the user to operate the beauty device 1 while wearing it. As a result, the user can perform tasks other than beauty work while the beauty device 1 is operating. If the beauty device 1 is configured to be separable into multiple devices, the manner in which the beauty device 1 is worn by the user may include a manner in which all of the multiple devices are worn by the user and a manner in which at least one of the multiple devices is worn by the user.

[0020] As shown in FIG. 1 , the beauty device 1 is, for example, a mask-type beauty device worn on the user's head. The user's head may be, for example, at least one of the face, head, and neck. In this embodiment, the beauty device 1 irradiates light toward the user's face. The beauty device 1 also 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 through the air and reach the user's face.

[0021] In this embodiment, the beauty device 1 includes a cover 10, one or more (sometimes referred to as one or more) ultrasound emission units 20, one or more light irradiation units 30, and a protective member 40. Each component of the beauty device 1 will be described in detail.

[0022] [Cover 10] In this embodiment, the cover 10 is configured to be wearable by a user. The cover 10 is configured to be detachable by the user. For example, the cover 10 is configured to cover the face of the user when the beauty device 1 is used. According to this embodiment, the user can wear the beauty device 1 by wearing the cover 10 on the user's head.

[0023] In this embodiment, one or more ultrasound emission units 20 and one or more light emission units 30 are arranged on the cover 10. In this embodiment, the cover 10 supports one or more ultrasound emission units 20 and one or more light emission units 30.

[0024] In the present embodiment, the cover 10 supports the one or more ultrasound emitters 20 and the one or more light irradiators 30 so that, when the cosmetic device 1 is worn by a user, ultrasound emitted (sometimes referred to as irradiation, emission, or projection) from at least one of the one or more ultrasound emitters 20 and light emitted (sometimes referred to as irradiation, emission, or projection) from at least one of the one or more light irradiators 30 reach a part of the user's body (sometimes referred to as a target area). As a result, for example, when the cosmetic device 1 is worn by a user, the cosmetic device 1 receives an instruction to emit ultrasound and / or light, and the ultrasound and / or light are emitted from the cosmetic device 1 toward the target area. The timing at which the ultrasound is emitted and the timing at which the light is emitted may be substantially the same or different.

[0025] The target area may be a single area or two or more areas. Examples of the target area include the entire face, the entire face (excluding the area to be protected), the forehead, temples, cheeks, nose, nasolabial folds, and / or jawline. The target area may be an area adjacent to the above-mentioned area to be protected, or may be set so as to surround the area to be protected.

[0026] In the present embodiment, the cover 10 supports one or more ultrasound emitters 20 so that, when the cosmetic device 1 is worn by a user, the target area is spaced apart from the ultrasound emitter 20 that emits ultrasound to the target area. Similarly, the cover 10 supports one or more light irradiators 30 so that, when the cosmetic device 1 is worn by a user, the target area is spaced apart from the light irradiators 30 that emit light to the target area. This allows for the realization of a wearable device that includes one or more ultrasound emitters 20 and one or more light irradiators 30.

[0027] The cover 10 has an outer surface 10A that faces outward when seen from the user, and an inner surface 10B that faces the user when the cover 10 is worn by the user.

[0028] The cover 10 has openings 10e1 and 10e2 that penetrate the cover 10 at positions corresponding to the eyes when the user wears the cover 10. Each of the openings 10e1 and 10e2 may be left open with nothing provided therein, or may be provided with, for example, a transparent plate, a half mirror, a mesh, or the like.

[0029] Furthermore, the cover 10 has an opening 10n that penetrates the cover 10 at a position that corresponds to the nose when the cover is worn by a user. The cover 10 has a mesh member 10n1 (mesh) that is provided at the opening 10n and covers the opening 10n. Furthermore, the cover 10 has an opening 10m that penetrates the cover 10 at a position that corresponds to the mouth when the cover is worn by a user. The cover 10 has a mesh member 10m1 (mesh) that is provided at the opening 10m and covers the opening 10m. Note that the openings 10n and 10m may each be left open with nothing provided therein.

[0030] Each of the openings 10e1 and 10e2 is an example of a first opening, and each of the openings 10m and 10n is an example of a second opening.

[0031] The specific acoustic impedance of each of the mesh members 10n1 and 10m1 is, for example, 5×10 6 The specific acoustic impedance of air is preferably equal to or greater than pascal-seconds per cubic meter. The specific acoustic impedance of air is approximately 430 pascal-seconds per cubic meter. Therefore, by increasing the difference in the specific acoustic impedance of air, the reflection of ultrasonic waves can be increased at the boundaries between the mesh member 10n1 and the air and the mesh member 10m1.

[0032] The specific acoustic impedance of the material constituting the mesh members (mesh member 10n1, mesh member 10m1) is 5 × 10 6 Pascal seconds per cubic meter or more, and the specific acoustic impedance of the mesh material is 5 x 10 6 The surface of the material constituting the mesh member may have a specific acoustic impedance of 5 x 10 6 By depositing a material with a specific acoustic impedance of 5 x 10 Pascal seconds per cubic meter or more, 6 Pascal seconds per cubic meter or more may be used. Specific acoustic impedance is 5 × 10 6 Materials with a thermal conductivity of pascal seconds per cubic meter or greater include, for example, copper and aluminum.

[0033] The cover 10 is formed of, for example, resin, such as acrylonitrile-butadiene-styrene resin (ABS resin), polycarbonate (PC), polypropylene (PP), polyethylene terephthalate (PET), polyacetal (POM), polycyclohexylene dimethylene terephthalate (PCT), fiber reinforced plastics (FRP), polybutylene succinate (PBS), or a combination thereof.

[0034] The cover 10 may be made of, for example, a metal, and may include, for example, stainless steel (SUS), titanium (Ti), iron (Fe), aluminum (Al), or a combination thereof.

[0035] Although the cover 10 is formed to cover the entire face of the user (full size), the cover in the beauty device according to the first embodiment may be formed to cover, for example, the upper or lower half of the face (half size).

[0036] The cover 10 includes a band 11 and a band 12 that are used to secure the cover 10 when the cover 10 is attached to the user's face. When the beauty device 1 is attached to the user, the band 11 comes into physical contact with a part of the user's body (sometimes referred to as the attachment site). When the beauty device 1 is attached to the user, the band 12 comes into physical contact with the attachment site. This achieves the beauty device 1 or the cover 10 that is configured to be attachable to the user.

[0037] In this embodiment, the bands 11 and 12 are joined at the back of the user's head. By joining the bands 11 and 12 at the back of the user's head, the cover 10 is fixed to the user. The bands 11 and 12 may be joined by, for example, hook and loop fasteners, wire fasteners, hooks, buttons, snap buttons, magnetic buttons, etc. The bands 11 and 12 may also be joined by, for example, tying the bands 11 and 12 together.

[0038] The cosmetic device 1 may include a bonding strength adjustment unit (not shown) for adjusting the bonding strength of the bands 11 and 12. The bonding strength adjustment unit may electrically tighten or loosen the bands 11 and 12.

[0039] The cosmetic device 1 may be an example of a device. The cover 10 may be an example of a main body or a support part. The band 11 may be an example of a wearing part. The band 12 may be an example of a wearing part. A structure including the cover 10 and at least one of the bands 11 and 12 may be an example of a main body. At least one of the one or more ultrasound emission parts 20 may be an example of an ultrasound emission part. At least one of the one or more light irradiation parts 30 may be an example of a light emission part. The protective member 40 may be an example of a protection part or a wearing part. The user's face may be an example of a target part. The user's eyes may be an example of a part to be protected. The first part may be an example of a target part. The second part may be an example of a target part. The first part and the second part may occupy different areas of the user's body.

[0040] [Ultrasonic wave emission unit 20] When the beauty device 1 is worn by a user, the ultrasound emitter 20 emits ultrasound toward the user's face. The beauty device 1 includes a plurality of ultrasound emitters 20 on the inner surface 10B of the cover 10. The number of ultrasound emitters 20 may range from 1 to 500, for example.

[0041] The ultrasound emitter 20 emits, for example, sounds in the range of 10 kHz to 50 kHz toward the user's skin. For example, it is desirable that the ultrasound emitter 20 particularly emit ultrasound waves in the vicinity of 20 kHz. Furthermore, the ultrasound emitter 20 emits, for example, ultrasound waves with a sound pressure level in the range of 20 decibels to 100 decibels toward the user's skin. For example, it is desirable that the ultrasound emitter 20 particularly emit ultrasound waves with a sound pressure level of 70 decibels.

[0042] The range over which one ultrasonic wave emitter 20 emits ultrasonic waves may be, for example, in the range of 1 to 10 millimeters in diameter when concentrating ultrasonic waves, or in the range of 10 to 300 millimeters in diameter when diffusing ultrasonic waves.

[0043] The ultrasonic wave emitter 20 may include an ultrasonic wave source that emits ultrasonic waves and a first irradiation range adjuster for adjusting the irradiation range of the ultrasonic waves emitted from the ultrasonic wave source. Examples of the first irradiation range adjuster include (a) a mirror or a variable focus mirror, and (b) (i) an actuator for adjusting the distance between the output end of the ultrasonic wave source and the inner surface 10B of the cover 10, and / or (ii) the attitude of the ultrasonic wave source. Examples of the variable focus mirror include a mirror array (including a micromirror array).

[0044] The ultrasound emitting unit 20 emits ultrasound to a region (sometimes referred to as a first region) including at least one of the forehead, temples, cheeks, nose, nasolabial folds, and face line, for example.

[0045] The ultrasonic wave emitting unit 20 may be configured to be movable on the cover 10. For example, the ultrasonic wave emitting unit 20 may be configured to be slidable on the cover 10. The ultrasonic wave emitting unit 20 may be configured to be detachable from a predetermined position on the cover 10. The ultrasonic wave emitting unit 20 may be configured to be rotatable with respect to the cover 10.

[0046] The ultrasound emitter 20 may be located, for example, at a distance in the range of 5 mm to 50 mm from the face.

[0047] If the distance from the ultrasonic wave emitter 20 to the user's skin changes, the effect on the skin may change. For example, if the distance from the ultrasonic wave emitter 20 to the user's skin changes, the sound pressure may not be appropriate for the skin. Therefore, the beauty device 1 may be configured to measure the distance from the ultrasonic wave emitter 20 to the user's skin. For example, the distance may be measured by detecting the sound emitted from the ultrasonic wave emitter 20 with a microphone or the like and calculating the distance from the time it takes for the sound to return. Alternatively, the distance may be measured using another detector, such as a laser range finder or an ultrasonic range finder.

[0048] According to this embodiment, multiple ultrasonic wave emitters 20 can be used simultaneously. Due to manufacturing errors, mass production variations, and the like, the natural frequencies of the multiple ultrasonic wave emitters 20 may differ slightly. In this case, depending on the frequency difference, sound waves may interfere with each other, causing beats. If a beat with a frequency of several Hz occurs, some users may find the beat unpleasant.

[0049] Therefore, according to one embodiment, the control device of the cosmetic device 1 (e.g., the overall control unit 110 described below) controls the operation of the multiple ultrasonic wave emitters 20 so that the absolute value of the difference between the frequencies of the multiple ultrasonic waves emitted by each of the multiple ultrasonic wave emitters 20 is greater than a predetermined value within the frequency range of the ultrasonic waves irradiated to the user. The predetermined value may be any value between 10 and 30 Hz. According to another embodiment, the cosmetic device 1 may measure sound with a microphone while the ultrasonic wave emitters 20 are operating, and adjust the frequency of the multiple ultrasonic wave emitters 20 by, for example, adjusting a variable resistor in the drive circuit. According to yet another embodiment, the cosmetic device 1 may include a beat absorbing material that absorbs or attenuates beats with a frequency of several Hz. The cosmetic device 1 may also include earplugs or a housing that absorbs or attenuates beats with a frequency of several Hz.

[0050] Furthermore, because high-frequency sound waves have high directionality, they may only reach a limited range in the ultrasound emission unit 20. Therefore, the beauty device 1 may be equipped with masks, reflectors (particularly metal plates with high acoustic reflectivity), sound-adjusting panels, glass wool, etc., in several locations to scatter and diffuse the ultrasound. Furthermore, the beauty device 1 may be equipped with multiple resonating vibration plates in front of the ultrasound emission unit 20.

[0051] Furthermore, since the beauty device 1 may be used while cosmetics are applied, the ultrasound emission unit 20 needs to be waterproofed. Covering the ultrasound emission unit 20 with a waterproof member for waterproofing purposes may result in a loss of sound pressure. Therefore, the beauty device 1 covers the ultrasound emission unit 20 with a waterproof elastic material that has little effect on the propagation of ultrasound. Specifically, it is desirable to use an elastic material with an elastic modulus of 0.1 MPa to 50 MPa and an ultrasound attenuation rate of 0.1 to 0.3. For example, it is desirable to use silicone rubber or urethane rubber. Alternatively, the ultrasound emission unit 20 may be placed in a location that is less likely to get wet, and the ultrasound reflected by the elastic material may provide waterproofing.

[0052] [Light irradiation unit 30] When the beauty device 1 is worn by a user, the light irradiating unit 30 irradiates light toward the user's face. The beauty device 1 includes a plurality of light irradiating units 30 on the inner surface 10B of the cover 10. The number of light irradiating units 30 may be, for example, 1 to 500.

[0053] The light irradiating unit 30 includes, for example, a light-emitting diode (LED) and a laser diode (LD).

[0054] The light emitting unit 30 may irradiate the light from the light emitting element directly toward the user, or may irradiate the light from the light emitting element toward the user via an optical member. The light emitting unit 30 is preferably, for example, of a general waterproof specification.

[0055] The light irradiating unit 30 irradiates, for example, visible light. The range of visible light irradiated by the light irradiating unit 30 is, for example, a wavelength range of 380 to 800 nanometers, particularly a range of 600 to 800 nanometers.

[0056] The light irradiating unit 30 irradiates, for example, near-infrared light. The range of the near-infrared light irradiated by the light irradiating unit 30 is, for example, a wavelength range of 800 nanometers to 1 millimeter, particularly, a range of 800 nanometers to 2.5 micrometers.

[0057] Note that a light irradiating unit that irradiates visible light and a light irradiating unit that irradiates near-infrared light may be mixed as the light irradiating unit 30. Also, light irradiating units that irradiate visible light and near-infrared light with different wavelengths may be mixed.

[0058] The light irradiation unit 30 irradiates the face with light in the range of, for example, 50 milliwatts per square centimeter to 500 milliwatts per square centimeter, and may be positioned at a distance of, for example, 5 millimeters to 50 millimeters from the face.

[0059] The range of light emitted by one light emitting unit 30 may be, for example, 1 to 10 millimeters in diameter when the light is concentrated, or may be, for example, 10 to 300 millimeters in diameter when the light is diffused.

[0060] The light irradiation unit 30 may include a light source that emits light and a second irradiation range adjustment unit that adjusts 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 mirror or a variable focus mirror, (b) a lens or a variable focus lens, and (c) an actuator that adjusts (i) the distance between the output end of the light source and the inner surface 10B of the cover 10, and / or (ii) the attitude of the light source. Examples of the variable focus mirror include a mirror array (including a micromirror array). Examples of the variable focus lens include a lens array (including a microlens array), a liquid lens, a metalens, etc.

[0061] The light irradiating section 30 irradiates light onto a region (sometimes referred to as a second region) including at least one of the forehead, temples, cheeks, nose, nasolabial folds, face line, eyelids, and neck, for example.

[0062] The light irradiation unit 30 may be configured to be movable on the cover 10. For example, the light irradiation unit 30 may be configured to be slidable on the cover 10. The light irradiation unit 30 may be configured to be detachable from a predetermined position on the cover 10. The light irradiation unit 30 may be configured to be rotatable with respect to the cover 10.

[0063] [Protective member 40] The protective member 40 protects the user's eyes from ultrasonic waves and light. The protective member 40 is provided so as 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.

[0064] The protective member 40 includes a contact portion 41 and a tubular portion 42. The contact portion 41 is provided on the user side of the tubular portion 42. The contact portion 41 may be an example of an attachment portion.

[0065] The contact portion 41 is the portion that comes into contact with the user's skin. The contact portion 41 is formed of, for example, a thermoplastic or thermosetting elastomer. The hardness (durometer hardness) of the elastomer that forms the protective member 40 is, for example, anywhere in the range of A10 to A90.

[0066] The cylindrical portion 42 is provided so as to surround the user's eyes when viewed from the front. The cylindrical portion 42 is formed, for example, from a resin. The cylindrical portion 42 is formed, for example, from acrylonitrile-butadiene-styrene resin (ABS resin), polycarbonate (PC), polypropylene (PP), polyethylene terephthalate (PET), polyacetal (POM), polycyclohexylene dimethylene terephthalate (PCT), fiber reinforced plastics (FRP), polybutylene succinate (PBS), or a combination thereof. The cylindrical portion 42 may also be formed from a metal. The cylindrical portion 42 may be formed, for example, from copper, aluminum, or the like.

[0067] The protective member 40 has a specific acoustic impedance of 5×10 6 Includes materials with a specific acoustic impedance of 5 x 10 Pascal-seconds per cubic meter or greater. 6 When the protective member 40 contains a material with a conductivity of at least pascal-seconds per cubic meter, ultrasonic waves are reflected by the protective member 40. Reflection of ultrasonic waves by the protective member 40 can prevent the ultrasonic waves from leaking to the outside. Reflection of ultrasonic waves by the protective member 40 also returns the ultrasonic waves to the user side, allowing the ultrasonic waves to be used effectively.

[0068] The ultrasonic attenuation rate in the protective member 40 may 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, or 95% or more. The attenuation rate may be 100% or less, 95% or less, 90% or less, 80% or less, 70% or less, 60% or less, 50% or less, 40% or less, 30% or less, 20% or less, or 10% or less. The attenuation rate may be any value between 5% and 100%, any value between 10% and 100%, any value between 5% and 95%, any value between 10% and 90%, or any value between 20% and 60%. This can protect the area to be protected from ultrasound.

[0069] The attenuation rate of ultrasonic waves in the protective member 40 is more preferably 30% or more, even more preferably 50% or more, and particularly preferably 60% or more, so that the area to be protected can be adequately protected.

[0070] The ultrasonic reflectivity of the protective member 40 may 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, or 95% or more. The reflectivity may be 100% or less, 95% or less, 90% or less, 80% or less, 70% or less, 60% or less, 50% or less, 40% or less, 30% or less, 20% or less, or 10% or less. The reflectivity may be any value between 5% and 100%, any value between 10% and 100%, any value between 5% and 95%, any value between 10% and 90%, or any value between 20% and 60%. This can protect the area to be protected from ultrasound.

[0071] The reflectance of ultrasonic waves in the protective member 40 is more preferably 30% or more, even more preferably 50% or more, and particularly preferably 60% or more, so that the area to be protected can be adequately protected.

[0072] The light transmittance of the protective member 40 may be 80% or less, 70% or less, 60% or less, 50% or less, 40% or less, 30% or less, 20% or less, 10% or less, or 5% or less. The above transmittance may even be 0%. This allows the area to be protected from light.

[0073] The light transmittance of the protective member 40 is more preferably 40% or less, even more preferably 20% or less, and particularly preferably 10% or less, so that the area to be protected can be sufficiently protected.

[0074] In the protective member 40, when the contact portion 41 is made of, for example, rubber or resin, a material having a specific acoustic impedance of 5×10 6 In other words, the portion of the protective member 40 that does not come into contact with the user's face (the non-contact portion, for example, the inside of the contact portion 41) may be made of a material having a specific acoustic impedance of 5×10 6 It may be made of a material with a viscosity of pascal seconds per cubic meter or greater.

[0075] In addition, at least one of the ultrasound emission unit 20 and the light irradiation unit 30 may be disposed in the cylindrical portion .

[0076] Next, a description will be given of the operation of the beauty device according to embodiment 1. Fig. 5 is a diagram illustrating the functional configuration of beauty device 1, which is an example of the beauty device according to embodiment 1.

[0077] The beauty device 1 includes a control unit 100 that controls and drives the ultrasound emission unit 20 and the light irradiation unit 30. The control unit 100 includes an overall control unit 110, an ultrasound drive unit 120, and a light drive unit .

[0078] The overall control unit 110 controls the entire beauty device 1. The overall control unit 110 controls the ultrasound driving unit 120 and the light driving unit 130. The overall control unit 110 is, for example, a computer including a CPU (Central Processing Unit), RAM (Random Access Memory), and ROM (Read Only Memory). The overall control unit 110 executes processing by, for example, reading a program stored in the ROM into the RAM and executing the program with the CPU.

[0079] The ultrasonic driving unit 120 drives the ultrasonic emission unit 20 to emit ultrasonic waves from the ultrasonic emission unit 20 under the control of the overall control unit 110. For example, when the overall control unit 110 issues a command to emit ultrasonic waves, the ultrasonic driving unit 120 generates a drive signal having a predetermined voltage waveform for driving an ultrasonic generating element included in the ultrasonic emission unit 20. The ultrasonic driving unit 120 then supplies the generated drive signal to the ultrasonic emission unit 20. The ultrasonic emission unit 20, to which the drive signal has been supplied, emits ultrasonic waves.

[0080] The ultrasonic driving unit 120 drives the plurality of ultrasonic emission units 20. The ultrasonic driving unit 120 may switch the ultrasonic emission units 20 to which the drive signals are supplied by using a switching circuit such as a demultiplexer, for example.

[0081] The light driving unit 130 drives the light emitting unit 30 to emit light (visible light or near-infrared light) from the light emitting unit 30 under the control of the overall control unit 110. For example, when the overall control unit 110 issues a command to emit light, the light driving unit 130 generates a drive signal having a predetermined voltage waveform for driving a light emitting element included in the light emitting unit 30. The light driving unit 130 then supplies the generated drive signal to the light emitting unit 30. The light emitting unit 30, to which the drive signal has been supplied, emits light.

[0082] The light driving section 130 drives the plurality of light irradiating sections 30. The light driving section 130 may switch the light irradiating sections 30 to which the drive signal is supplied, for example, by using a switching circuit such as a demultiplexer.

[0083] The overall control unit 110 may control the output of ultrasound and light to be continuous and simultaneous, or may control the output of ultrasound and light to be alternately. For example, the overall control unit 110 may control the output to be alternately in the order of light, ultrasound, light, and ultrasound, or may control the output to be alternately in the order of ultrasound, light, ultrasound, and light. Note that, for example, the overall control unit 110 may control the output to be alternately in the order of light, ultrasound, light, and ultrasound, and then pause the output, and then again alternately in the order of light, ultrasound, light, and ultrasound. Similarly, the overall control unit 110 may control the output to be alternately in the order of ultrasound, light, ultrasound, and light, and then pause the output, and then again alternately in the order of ultrasound, light, ultrasound, and light.

[0084] Furthermore, the overall control unit 110 may perform control so that ultrasonic waves and light are repeatedly output while changing the intensities of the respective waves. For example, the overall control unit 110 may perform control so that strong light, strong ultrasonic waves, weak light, and weak ultrasonic waves are output alternately in this order, or so that weak light, weak ultrasonic waves, strong light, and strong ultrasonic waves are output alternately in this order.

[0085] Furthermore, the overall control unit 110 may control the output of ultrasound and light repeatedly while changing the type of light to be irradiated. For example, the overall control unit 110 may control the output to alternate in the order of visible light, ultrasound, near-infrared light, and ultrasound. Furthermore, the overall control unit 110 may change the intensity of ultrasound while changing the type of light to be irradiated. For example, the overall control unit 110 may control the output to alternate in the order of visible light, strong ultrasound, near-infrared light, and weak ultrasound, or may control the output to alternate in the order of visible light, weak ultrasound, near-infrared light, and strong ultrasound.

[0086] Furthermore, the overall control unit 110 may perform control so that output periods during which ultrasound and light are output (emitted or irradiated) and pause periods during which the output is paused are alternately provided. The overall control unit 110 may perform control so that the output periods are the same length as the pause periods, or so that the output periods are longer than the pause periods, or so that the output periods are shorter than the pause periods.

[0087] Furthermore, the overall control unit 110 may control the output period of the ultrasound to be the same length as the output period of the light, or may control them to be different lengths. Similarly, the overall control unit 110 may control the pause period of the ultrasound to be the same length as the pause period of the light, or may control them to be different lengths.

[0088] Moreover, the overall control unit 110 may control the ratio between the output period and the pause period in the ultrasonic wave to be the same as or different from the ratio between the output period and the pause period in the light.

[0089] Furthermore, the overall control unit 110 may be configured to have a plurality of modes. For example, the overall control unit 110 may be configured to have a "barrier function recovery mode," a "dark circles / dull skin mode," a "beautiful skin mode," a "restorative sleep mode," a "wake-up mode," etc.

[0090] The "barrier function recovery mode" is, for example, a mode for recovering the barrier function of the skin. The overall control unit 110 controls the device to output, for example, ultrasonic waves.

[0091] The "dark circles / dullness mode" is a mode for improving dark circles and dullness of the skin, for example. The overall control unit 110 controls the device to output infrared light, for example.

[0092] The "beautiful skin mode" is a mode for improving, for example, moisture, firmness, and luster. The overall control unit 110 controls the output of, for example, visible light, particularly red light.

[0093] The "sleep mode" is a mode for operating the beauty device 1 when the user is sleeping, for example. The overall control unit 110 controls the beauty device 1 to reduce the intensity of the ultrasound and light, for example, so as not to give excessive stimulation to the user.

[0094] The "wake-up mode" is a mode for operating the beauty device 1 to wake up a sleeping user, for example. The overall control unit 110 controls the beauty device 1 to increase the intensities of the ultrasound and light, for example, to wake up the user.

[0095] Moreover, the overall control unit 110 may perform control such that, for example, whether to maintain the mode, stop the mode, change the mode, etc. is changed using a button, etc. Furthermore, the overall control unit 110 may change or fine-tune parameters in each mode based on, for example, the diagnosis results.

[0096] When using the beauty device 1, it may be difficult to operate an operating unit such as a controller due to limited visibility. Furthermore, adding a new remote controller or the like may increase costs and make management cumbersome. Therefore, the beauty device 1 may be configured to allow facial gesture input. For example, the beauty device 1 may use an acceleration sensor to detect facial movements and turn the power on and off or switch modes. Furthermore, the beauty device 1 may detect taps on a mask and turn the power on and off or switch modes.

[0097] According to the beauty device according to the first embodiment, in a beauty device that emits ultrasonic waves to a user and irradiates the user with light, it is possible to protect the eyes and prevent leakage of ultrasonic waves.

[0098] In this embodiment, the inner surface 10B of the cover 10 may be configured to retroreflect at least one of ultrasound and light. For example, retroreflection of light is a reflection in which reflected light returns in a direction substantially along the optical path of the incident light. The same applies to retroreflection of ultrasound. This allows for precise control of the amount of ultrasound and / or light irradiation. Furthermore, ultrasound and / or light can be efficiently irradiated.

[0099] For example, in the beauty device 1, a retroreflective material is attached to at least a portion of the inner surface 10B of the cover 10 where the ultrasound emission unit 20 and the light irradiation unit 30 are not provided. An example of the retroreflective material is a retroreflective sheet. The retroreflective material may be, for example, a retroreflective material including a corner cube or a corner mirror, or a retroreflective material including glass beads.

[0100] In addition, in the beauty device according to the first embodiment, the inner surface of the cover is configured to have a specific acoustic impedance of, for example, 5×10 so that ultrasonic waves are reflected by the inner surface of the cover. 6 It may be made of a material with a viscosity of pascal seconds per cubic meter or greater.

[0101] In the example of the beauty device 1 described above, the beauty device 1 is fixed by joining the band 11 and the band 12 at the back of the head, but the fixing method for the beauty device according to the first embodiment is not limited to the above example. For example, the beauty device according to the first embodiment may be fixed by being hung on the ear. Also, for example, the beauty device according to the first embodiment may be fixed by being hung on the nose.

[0102] For example, when the beauty device according to the first embodiment is hung on the ear, the beauty device according to the first embodiment may stimulate the ear. For example, the beauty device according to the first embodiment may impart electrical stimulation, sound stimulation, heat stimulation, and / or vibration stimulation to the ear.

[0103] For example, the beauty device 1 according to the first embodiment has a "calming mode" for calming the autonomic nerves. When the overall control unit 110 receives a signal indicating that the user has selected the calming mode, the overall control unit 110 may determine to output a sound in the audible range (for example, 20 to 40 Hz). The overall control unit 110 may determine to output a predetermined type of sound. Examples of the predetermined type of sound include music content and ASMR content. The overall control unit 110 may acquire these contents from the user's terminal or from a server via a communication line. The overall control unit 110 may determine to output a sound in the range of 20 to 40 Hz at a tempo of 50 to 100 bpm. This allows the user to relax.

[0104] The overall control unit 110 may use the ultrasonic wave emitting unit 20 of the beauty device 1 as a parametric speaker and control the ultrasonic wave emitting unit 20 so that the ultrasonic wave emitting unit 20 outputs a sound in the audible range. If the beauty device 1 is equipped with a speaker, the overall control unit 110 may control the speaker to output the above-mentioned sound.

[0105] The overall control unit 110 may use the ultrasound emitter 20 or the speaker as a means for transmitting a message. An example of a message is how to perform a specific movement. This allows the user to understand how to perform a specific exercise, for example.

[0106] In one embodiment, the cosmetic device 1 may include a first vibration element for vibrating the ear. In this case, the overall control unit 110 may control the first vibration element in accordance with the sound. In another embodiment, the cosmetic device 1 may include a second vibration element for vibrating the cover 10. In this case, the overall control unit 110 may control the second vibration element so that the cover 10 vibrates in accordance with the sound.

[0107] The overall control unit 110 may use the first vibration element or the second vibration element to assist or train the user in a specific movement. An example of the specific movement is breathing. This allows the beauty device 1 to notify the user of the timing of breathing through vibration. As a result, the user can train their breathing technique.

[0108] For example, if the beauty device according to the first embodiment is worn on the nose, the beauty device according to the first embodiment may stimulate the nose, for example, by warming the nose or removing blackheads by deriving ions.

[0109] Second Embodiment A beauty device according to a second embodiment will now be described. The beauty device according to the second embodiment includes a cover with a two-layer structure. The beauty device according to the second embodiment includes an ultrasound emission unit in one layer of the two-layer structure, and a light irradiation unit in the other layer of the two-layer structure.

[0110] The beauty device according to the second embodiment will be described in detail with reference to the drawings. Fig. 6 is a perspective view illustrating a cover 210, which is an example of a cover for a beauty device according to the second embodiment. Fig. 7 is a rear view illustrating the cover 210, which is an example of a cover for a beauty device according to the second embodiment. Figs. 6 and 7 are views illustrating a portion of the cover 210.

[0111] The cover 210 includes a substrate 210a and a substrate 210b. In other words, the cover 210 has a two-layer structure including the substrate 210a and the substrate 210b.

[0112] The substrate 210a is a substrate provided on the user side. The substrate 210a holds the ultrasound emission unit 20. The substrate 210a has an opening 210a1 penetrating the substrate 210a. The opening 210a1 is provided corresponding to the light emission unit 30 provided on the substrate 210b. Light emitted from the light emission unit 30 is irradiated from the opening 210a1 towards the user.

[0113] The substrate 210b is provided on the opposite side of the substrate 210a from the user. The substrate 210b holds the light emitting unit 30.

[0114] According to the beauty device of the second embodiment, the mounting density of the ultrasound emission units and the light irradiation units can be increased, thereby increasing the number of ultrasound emission units and light irradiation units that can be mounted on the cover.

[0115] In the above example, the ultrasonic wave emitting unit 20 is provided on the substrate 210a and the light emitting unit 30 is provided on the substrate 210b, but it is also possible to provide the light emitting unit 30 on the substrate 210a and the ultrasonic wave emitting unit 20 on the substrate 210b.

[0116] Third Embodiment A beauty device according to a third embodiment will be described. The beauty device according to the third embodiment has a modularized cover.

[0117] The beauty device according to the third embodiment will be described in detail with reference to the drawings. Fig. 8 is a front view illustrating a beauty device 301, which is an example of the beauty device according to the third embodiment.

[0118] The cosmetic device 301 includes a cover 310. The cover 310 includes a main body 311, an upper module 312, and a lower module 313. The upper module 312 and the lower module 313 are each connectable to the main body 311 in a replaceable manner.

[0119] The main body unit 311 is provided at a position corresponding to the area around the user's eyes. The main body unit 311 has an ultrasound emission unit and a light irradiation unit on the inner surface facing the user. The main body unit 311 provides care for the area around the user's eyes using ultrasound and light. The main body unit 311 is fixed to the user's head. For example, if the main body unit 311 is equipped with a battery, it is desirable to provide the battery at the back of the head so that the center of gravity is in the center of the head.

[0120] The main body 311 may further include a massage module (not shown) for physically massaging a part of the user's body. The massage module may be arranged so that the massage module is located at the back of the user's head when the beauty device 1 is worn by the user. The massage module may include a vibration device for transmitting vibrations to the user.

[0121] The upper module 312 is provided near the user's forehead. The upper module 312 is replaceably connected to the main body 311. The upper module 312 has an ultrasound emission unit and a light irradiation unit on the inner surface facing the user. The upper module 312 provides care around the user's forehead using ultrasound and light. Power is supplied to the upper module 312 from, for example, the main body 311. A plurality of types of upper module 312 with different specifications are provided so that preferred care can be provided depending on the condition and characteristics of the user's skin.

[0122] The lower module 313 is provided near the cheeks and mouth of the user. The lower module 313 is replaceably connected to the main body 311. The lower module 313 has an ultrasound emission unit and a light irradiation unit on the inner surface facing the user. The lower module 313 provides care for the area around the user's cheeks and mouth using ultrasound and light. The lower module 313 is supplied with power from, for example, the main body 311. A plurality of types of lower module 313 with different specifications are provided so that preferred care can be provided depending on the condition and characteristics of the user's skin.

[0123] For example, skin concerns vary depending on the individual and the area. Therefore, the care desired varies depending on the individual and the area. It is difficult to provide beauty devices with functions that cover all the care desired for various people and areas due to size and cost issues.

[0124] Therefore, the beauty device according to the third embodiment is modularized so that modules can be easily replaced. With the beauty device according to the third embodiment, by replacing modules, it is possible to deliver the energy required for care to the desired location.

[0125] <Modification> In the present embodiment, the details of the beauty device 1 have been described using an example in which the beauty device 1 is a mask-type wearable device. However, the beauty device 1 is not limited to this embodiment. In other embodiments, the beauty device 1 may be a headgear-type wearable device, or a neckband-type or shoulder-type wearable device. A headgear-type wearable device comes into physical contact with at least one part of the user's head. As described above, examples of parts of the head include the face, head, and neck. A neckband-type or shoulder-type wearable device comes into physical contact with the user's neck or shoulder.

[0126] For example, a neck-type beauty device attached to the neck can care for the skin on the face, chin, and neck without impairing the user's vision. The neck-type beauty device outputs, for example, ultrasound or light, which is non-contact energy, from the neck, where the user's vision is not obstructed. When outputting ultrasound or light, the direction of irradiation may be changed, for example, by installing an output element on a base equipped with one or more hinge mechanisms. The direction of irradiation may also be changed by reflecting the energy (ultrasound or light) using a direction-changeable reflecting element. Furthermore, the entire face may be irradiated with light intensity automatically adjusted according to the irradiation angle and distance. Furthermore, if there are any areas where irradiation is prohibited, such as the eyes, irradiation may be automatically avoided.

[0127] Although the above example describes a neck type, it is sufficient to provide a configuration that irradiates energy (ultrasound or light) in a range that does not obstruct the human field of vision, for example, at a position that is at least 10 centimeters above or below the eyeball.

[0128] In the case of a neck type, for example, the neck and shoulders may be physically massaged or warmed.

[0129] In this embodiment, the details of the cosmetic device have been described using as an example a case where a mesh member 10m1 and / or a mesh member 10n1 is disposed in the opening of the cosmetic device 1. 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 shape. In other embodiments, the covering member may be in the shape of a punched plate or a lattice. The covering member may be in the shape of a sponge or a porous body. The covering member may have a hollow structure. The covering member may have a hollow structure that is, for example, cone-shaped, hemispherical, semi-elliptical, tray-shaped, or box-shaped. The mesh member 10m1 may be an example of a covering member. The mesh member 10n1 may be an example of a covering member.

[0130] In the present embodiment, the details of the beauty device 1 have been described using an example in which the overall control unit 110 controls the beauty device 1 based on instructions from a user. However, the overall control unit 110 is not limited to the present embodiment. In other embodiments, the overall control unit 110 may control the beauty device 1 based on instructions from an external information processing device. Examples of the external information processing device include an information processing device used by the user (e.g., a mobile terminal) and a server. Examples of the content of the instruction include the type of operation mode of the beauty device 1, the intensity of the operation, the duration of the operation, and the type of energy emitting module to be actually operated among the energy emitting modules installed in the beauty device 1. Examples of the energy emitting module include an RF module, an EMS module, an interference wave EMS module, an ultrasonic emitting module, and a light emitting module.

[0131] The external information processing device may output the instructions based on an image including the user's face as a subject, or the results of a medical interview with the user or a beauty consultant. The overall control unit 110 may output information such as the operation history, operation history, and user ID of the beauty device 1 to the external information processing device.

[0132] In the present embodiment, the beauty device 1 has been described in detail using an example in which the beauty device 1 includes modules that emit ultrasound and light. 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 ultrasound emission module, and a light emission module.

[0133] [Interference wave EMS module] For example, if the beauty device 1 includes an interference wave EMS module, the interference wave EMS module emits two or more carrier waves with different electrical characteristics. The electrical characteristics include at least one of voltage (sometimes referred to as amplitude), frequency, and phase. The interference wave EMS module includes three or more electrodes and a carrier wave output unit that outputs the two or more carrier waves to the three or more electrodes.

[0134] The carrier wave output unit, for example, (i) applies a first signal to any two of the three or more electrodes to generate a first carrier wave having a first electrical characteristic, and (ii) applies a second signal to one or two of the remaining electrodes to generate a second carrier wave having a second electrical characteristic. This outputs a carrier wave onto the user's body surface and / or into the user's body. The carrier wave output unit may apply the first signal and the second signal to each electrode based on instructions from the overall control unit 110.

[0135] The carrier wave output unit may apply a third signal to one or two of the electrodes to which the first signal and the second signal are not applied, to generate a third carrier wave having a third electrical characteristic. When the interference wave EMS module has four or more electrodes, the carrier wave output unit may not apply a signal to at least one of the electrodes. The first electrical characteristic and the second electrical characteristic differ in at least one of voltage, frequency, and phase. The first electrical characteristic and the third electrical characteristic differ in at least one of voltage, frequency, and phase. The second electrical characteristic and the third electrical characteristic differ in at least one of voltage, frequency, and phase.

[0136] The carrier wave output unit may, for example, apply a first signal to a plurality of electrode pairs to generate a plurality of first carrier waves. Similarly, the carrier wave output unit may, for example, apply a second signal to a plurality of electrode pairs to generate a plurality of second carrier waves. The carrier wave output unit may, for example, apply a third signal to a plurality of electrode pairs to generate a plurality of third carrier waves.

[0137] For example, if the interference wave EMS module has three electrodes (electrode A, electrode B, and electrode C), the three electrodes are placed on the user's body surface. This forms (i) a first electric circuit including the carrier wave output unit, electrode A, a part of the user's body, and electrode B, and (ii) a second electric circuit including the carrier wave output unit, electrode C, a part of the user's body, and electrode B. The carrier wave output unit applies a first signal to electrode A and electrode B. This generates a first carrier wave in an area located between electrode A and electrode B on the user's body surface and / or inside the user's body. Similarly, the carrier wave output unit applies a second signal to electrode C and electrode B. This generates a second carrier wave in an area located between electrode C and electrode B on the user's body surface and / or inside the user's body. Interference between the first carrier wave and the second carrier wave occurs on the user's body surface and / or inside the user's body, generating an interference wave according to the difference in electrical characteristics between the first carrier wave and the second carrier wave.

[0138] For example, if the interference wave EMS module has four electrodes (electrode A, electrode B, electrode C, and electrode D), the four electrodes are placed on the user's body surface. This forms (i) a first electric circuit including the carrier wave output unit, electrode A, a part of the user's body, and electrode B, and (ii) a second electric circuit including the carrier wave output unit, electrode C, a part of the user's body, and electrode D. The carrier wave output unit applies a first signal to electrode A and electrode B. This generates a first carrier wave in an area located between electrode A and electrode B on the user's body surface and / or inside the user's body. Similarly, the carrier wave output unit applies a second signal to electrode C and electrode D. This generates a second carrier wave in an area located between electrode C and electrode D on the user's body surface and / or inside the user's body. Interference between the first carrier wave and the second carrier wave occurs on the user's body surface and / or inside the user's body, generating an interference wave according to the difference in electrical characteristics between the first carrier wave and the second carrier wave.

[0139] [Waveform patterns of the first and second signals] (Waveform pattern for repeating muscle contraction and relaxation) In this embodiment, the carrier wave output unit determines waveform patterns of the first signal and the second signal so that a period (sometimes referred to as an on period) in which one or more interference waves having amplitudes greater than a first threshold are generated on the surface of and / or inside the user's body and a period (sometimes referred to as an off period) in which no interference waves having amplitudes greater than the first threshold are generated are repeated. The first threshold is determined, for example, so that the peak value of the amplitude of the interference waves generated in the off period is 10% or less of the peak value of the amplitude of the interference waves generated in the on period.

[0140] The technical significance of the on period and the off period is as follows: In this embodiment, for the purpose of simplifying the explanation, the technical significance of the on period and the off period will be explained using as an example a case where a period (pattern period) consisting of a single on period and a single off period is generated multiple times.

[0141] According to this embodiment, for example, the user's muscles contract during the on period and relax during the off period. By appropriately adjusting the length of the on period and the length of the off period, the pumping effect of the muscles is expected to improve blood flow, remove waste products, improve bodily fluid circulation, and restore, revive, or regenerate capillary function. As a result, (i) elimination of swelling, and (ii) improvement of skin dullness, firmness, and / or turnover, etc., can be expected. By eliminating swelling, a facial slimming effect can also be expected. Furthermore, repeated muscle contraction and relaxation is expected to have effects such as muscle hypertrophy and muscular shaping. As a result, effects such as improvement of facial sagging and lifting of the facial shape can be expected.

[0142] The pattern section may include at least one on period and at least one off period. The pattern section may include, for example, n on periods and n off periods, where n is an integer equal to or greater than 1. The carrier wave output section may determine the waveform patterns of the first and second signals so that the same type of pattern section is repeated, or may determine the waveform patterns of the first and second signals so that a plurality of different types of pattern sections are generated.

[0143] In this embodiment, the carrier wave output unit determines the waveform patterns of the first and second signals so that the length of the period during which the muscle is contracted (sometimes referred to as the contraction period) in the pattern section is shorter than the length of the period during which the muscle is not contracted or relaxed (sometimes referred to as the relaxation period). When a muscle starts contracting from a fully relaxed state, the muscle can be stimulated at its maximum range of motion. Therefore, when the contraction period is shorter than the relaxation period, the muscle hypertrophy effect is expected to be improved compared to when the contraction period is longer than the relaxation period. As a result, effects such as improvement of facial sagging and lifting of the facial shape can be expected. Furthermore, in this case, deceleration and / or backflow of blood and / or bodily fluid circulation can be suppressed. This is expected to improve the muscle pumping effect. As a result, (i) elimination of swelling and (ii) improvement of dullness, firmness, and / or turnover of the skin can be expected. Eliminating swelling can also be expected to make the face look smaller.

[0144] In one embodiment, a first pattern section including a first on period, a first off period, a second on period, and a second off period in this order is repeated. In the first pattern section, the length of the second off period may be longer than the length of the first off period. This makes the length of the contraction period shorter than the length of the relaxation period.

[0145] In another embodiment, a first pattern section includes a first on period, a first off period, a second on period, and a second off period, in this order, and a second pattern section following one or more first pattern sections 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 this order. In the first pattern section, the length of the second off period may be longer than the length of the first off period. In the second pattern section, the length of the third off period may be longer than the lengths of the first off period and the second off period. This results in the length of the contraction period being shorter than the length of the relaxation period.

[0146] In yet another embodiment, a first pattern section including a first off period, a first on period, a second off period, and a second on period in this order is repeated. In the first pattern section, the length of the first off period may be longer than the length of the second off period. This results in the length of the contraction period being shorter than the length of the relaxation period.

[0147] In yet another embodiment, a first pattern section includes a first OFF period, a first ON period, a second OFF period, and a second ON period, in that order, and a second pattern section following one or more first pattern sections 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 that order. In the first pattern section, the length of the first OFF period may be longer than the length of the second OFF period. In the second pattern section, the length of the first OFF period may be longer than the lengths of the second OFF period and the third OFF period.

[0148] In this embodiment, the carrier wave output unit may determine the waveform patterns of the first signal and the second signal so that, in each of one or more pattern sections, the ratio of the maximum length of one or more off periods included in each pattern section to the length of each pattern section exceeds 50%. This ratio may be 60% or more, 70% or more, 75% or more, 80% or more, or 90% or more. The ratio is preferably 70% or more, more preferably 75% or more, and particularly preferably 80% or more. This makes it possible to significantly observe the above-mentioned effects.

[0149] (Amplitude control of interference wave during a single pattern period) In this embodiment, when a single pattern section includes multiple on periods and multiple off periods, the carrier wave output unit may determine the waveform patterns of the first signal and the second signal such that the maximum amplitudes of the interference wave in at least two on periods are different. When a single pattern section includes multiple on periods and multiple off periods, the carrier wave output unit may determine the waveform patterns of the first signal and the second signal such that the maximum amplitudes of the interference wave in each on period are different. In controlling the amplitude of the interference wave, the carrier wave output unit may (i) determine to abruptly increase or decrease the amplitude of the interference wave, (ii) determine to gradually increase or decrease the amplitude of the interference wave, (iii) determine to abruptly increase or decrease the amplitude of the interference wave, or (iv) determine to gradually increase or decrease the amplitude of the interference wave.

[0150] In the various embodiments described above, the details of the carrier wave output unit have been described using examples in which the carrier wave output unit determines various controls. However, the carrier wave output unit is not limited to these embodiments. In other embodiments, the overall control unit 110 may determine various controls, and the carrier wave output unit may operate based on instructions from the overall control unit 110.

[0151] In one embodiment, the carrier wave output unit determines the waveform patterns of the first and second signals so that the maximum amplitude of the interference wave included in the last on-period among multiple on-periods included in a single pattern section is greater than the maximum amplitude of the interference wave included in the other on-periods. This allows the amplitude of the interference wave to be gradually increased. In this case, since the load applied to the muscle increases gradually, fluctuations in the speed of muscle contraction can be suppressed compared to when the load applied to the muscle increases suddenly. As a result, maximum muscle strength can be efficiently improved.

[0152] In another embodiment, the waveform patterns of the first and second signals are determined so that the maximum amplitude of an interference wave included in a specific on-period is smaller than the maximum amplitude of an interference wave included in at least one on-period that follows the specific on-period. This allows the amplitude of the interference wave to be gradually increased. In this case, the load applied to the muscle increases gradually, which can suppress fluctuations in the speed of muscle contraction compared to when the load applied to the muscle increases suddenly. As a result, maximum muscle strength can be efficiently improved.

[0153] When increasing the amplitude of the interference wave, the carrier wave output unit may (i) determine to increase the voltages of both the first signal and the second signal, (ii) determine to increase the voltage of one of the first signal and the second signal while maintaining the voltage of the other of the first signal and the second signal, or (iii) determine to decrease the voltage of one of the first signal and the second signal and increase the voltage of the other of the first signal and the second signal in consideration of the decrease.When decreasing the amplitude of the interference wave, the carrier wave output unit may (i) determine to decrease the voltages of both the first signal and the second signal, (ii) determine to decrease the voltage of the other of the first signal and the second signal while maintaining the voltage of one of the first signal and the second signal, or (iii) determine to increase the voltage of one of the first signal and the second signal and decrease the voltage of the other of the first signal and the second signal in consideration of the increase.

[0154] The waveform of the interference wave reaching the maximum amplitude may be either linear or nonlinear, and may include amplitude increases and decreases before reaching the maximum amplitude.The waveform of the interference wave reaching the minimum amplitude may be either linear or nonlinear, and may include amplitude increases and decreases before reaching the minimum amplitude.

[0155] (Waveform pattern that adds fluctuation to the carrier wave) In this embodiment, the carrier wave output unit may determine the waveform patterns of the first signal and the second signal so that at least one electrical characteristic of the two or more carrier waves has a fluctuation. 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. This generates a carrier wave with a fluctuation similar to that of a human heart rate. As a result, it can be expected that the user's parasympathetic nervous system will become dominant. The carrier wave output unit may acquire information regarding the user's heart rate and determine the waveform patterns of the first signal and the second signal so that the carrier wave has approximately the same fluctuation as the user's heart rate.

[0156] In one embodiment, the carrier wave output unit determines the waveform patterns of the first signal and the second signal so that the electrical characteristics of two or more carrier waves have fluctuations and the frequency and / or amplitude of the interference wave have fluctuations. In another embodiment, the carrier wave output unit determines the waveform patterns of the first signal and the second signal so that the electrical characteristics of two or more carrier waves have fluctuations and the frequency and / or amplitude of the interference wave have substantially no fluctuations. For example, the carrier wave output unit determines the waveform patterns of the first signal and the second signal so that the electrical characteristics of two or more carrier waves have approximately the same fluctuations.

[0157] The multiple carrier waves output by the interference wave EMS module have fluctuations of 10 Hz or less. The multiple carrier waves have independent fluctuations. For example, the multiple carrier waves may have fluctuations while the frequency difference between them remains constant. Alternatively, the frequency difference between the multiple carrier waves may fluctuate. In this case, fluctuations in the carrier waves will also cause fluctuations in the interference waves. In particular, carrier waves with fluctuations of 1.08 Hz to 1.33 Hz are preferable. As a result, fluctuations at the same frequency as the heart rate will cause the parasympathetic nervous system to become dominant, which can be expected to reduce stress.

[0158] (Control taking into account skin surface impedance) The overall control unit 110 may determine to output a message to the user to prompt the user to use a base agent by controlling the impedance between the electrodes of the interference wave EMS module and the user's body surface to control the current path. The message output format is not particularly limited, but examples include text, images, sounds, voice, light, and vibration.

[0159] By applying a base to the user's body surface, the impedance between the electrodes of the interference wave EMS module and the user's body surface can be controlled. This allows the current path to be controlled. For example, by using a base with low conductivity and high resistance, the current path can be concentrated on the body surface. This is expected to improve the sensation of warmth on the body surface. By using a base with a high dielectric constant, impedance matching between the electrodes and the body surface can be achieved. This is expected to reduce power loss and unnecessary electrical stimulation that occurs between the electrodes and the body surface.

[0160] [Other features] (Control taking into account electrode shape) The carrier wave output unit may control the current distribution by adjusting the electrode shape. For example, when a triangular electrode is used to form an electrode pair, the electrodes are arranged so that their vertices face each other.

[0161] (A control method for contracting and heating muscles using carrier waves of an uncommon frequency) This electrical stimulation method contracts muscles at low frequencies while heating them. Heat is applied using a variety of methods, including electric current, ultrasound, non-contact electromagnetic waves, and contact-based heat transfer methods such as heaters, particularly medium-frequency currents with frequencies between 10 kHz and 1 MHz. Medium-frequency currents are output from two or more electrodes, and low frequencies are generated by interfering with each other. The temperature rise is controlled based on the temperature of the muscle being contracted, and the muscle temperature is adjusted to +1 to +3°C above the initial temperature before treatment, improving muscle elasticity and potentially enhancing the hypertrophy effect.

[0162] The temperature state of the muscle can be calculated by measuring the temperature of the skin surface with a temperature sensor such as a thermistor. Alternatively, a constant low-frequency stimulus determined by EMS or interference waves from two or more carrier waves can be applied to the muscle, and the temperature state of the muscle can be calculated from the difference in contraction movement due to the temperature state. Methods for measuring contraction movement include strain sensors, vibration sensors, optical sensors, and cameras. Alternatively, an ultrasonic sensor attached to an electrode can be used to indirectly measure contraction movement.

[0163] The amplitude and frequency of the carrier wave can be varied depending on the calculated temperature state of the muscle. If the temperature state of the muscle has risen by +3 degrees or more from the initial temperature, the frequency of the carrier wave may be lowered or the amplitude may be reduced, or both may be taken. If the temperature state of the muscle has fallen by -3 degrees or more from the initial temperature, the frequency of the carrier wave may be raised or the amplitude may be increased, or both may be taken.

[0164] During the off period, the frequencies of two or more carrier waves can be matched, or all but one carrier wave can be stopped, allowing muscle heating to continue. An efficient muscle stimulation method for increasing muscle strength is repeated high-load exercise at maximum range of motion. However, repeated stimulation with conventional EMS accumulates fatigue, reducing its effectiveness over time. Furthermore, if muscle fibers are not sufficiently warmed, their elasticity becomes insufficient, preventing exercise at maximum range of motion. Therefore, it is necessary to raise muscle temperature to soften and increase elasticity, while also promoting fluid circulation through heating to timely remove fatigue-causing substances. Heat transfer through the epidermis as a muscle warming method takes time to sufficiently warm the target muscle, and combining it with heating using electric current requires complex output adjustments to match the depth of the muscle to be stimulated with low frequency. Considering these factors, it is preferable to set the carrier wave frequency between 10 kHz and 1 MHz. This allows for setting the carrier wave in a band that generates heat, and low-frequency stimulation can be achieved with interference waves. It also provides a good balance between heat dissipation and heating, allowing for temperature control between 36°C and 40°C.

[0165] (Transdermal absorption occurs by contracting muscles using carrier waves) This stimulation method simultaneously achieves transdermal absorption and muscle contraction, using two or more medium-frequency waves for electrical stimulation. Three or more electrodes output medium-frequency waves, of which one or more pairs are muscle contraction electrodes positioned for muscle contraction, and one or more other pairs are transdermal absorption electrodes positioned for transdermal absorption. Muscle contraction can be achieved by generating interference waves using the medium-frequency waves output from the muscle contraction electrodes and the transdermal absorption electrodes as carrier waves. At least one of the pair of transdermal absorption electrodes is positioned so that it directly contacts the area where transdermal absorption is desired, such as wrinkles. This electrode positioning allows transdermal absorption to occur while stretching the area where transdermal absorption is desired. For example, if the goal is to reduce wrinkles, stretching the wrinkled area perpendicular to the wrinkles can achieve a uniform transdermal absorption effect in the area. Furthermore, muscle contraction occurring simultaneously with transdermal absorption creates a pumping effect, allowing the transdermally absorbed active ingredients to be applied over a wide area.

[0166] The device also includes a method for measuring the stretching state of the transdermal absorption site caused by muscle contraction, allowing the amplitude of the interference wave to be controlled according to the stretching state. Methods for determining the stretching state include strain sensors, vibration sensors, optical sensors, and cameras. An ultrasonic sensor attached to the transdermal absorption electrodes can also be used to indirectly measure the stretching state. In particular, when the target area is wrinkled, the position, depth, and size of the wrinkles can be measured in advance to guide the electrode contact position. The measurement method is image diagnosis, analyzing the position, depth, and size of wrinkles from facial images captured by a camera and setting coordinates for each wrinkle using facial feature points. Based on the wrinkle coordinate information, one or more pairs of muscle contraction electrodes and one or more pairs of transdermal absorption electrodes can be selected from the three or more electrodes in contact with the face. If the electrodes are not in the correct position, guidance can be provided by the device or an external device such as a smartphone app. Considering the above, it is preferable to set the frequency of the interference wave between 1 Hz and 30 Hz. This constantly promotes blood and body fluid circulation, allowing the active ingredients in the stratum corneum to be quickly recovered.

[0167] (Assess stress levels and alleviate stress) This interference wave generator is equipped with a pulse sensor or electrocardiograph that measures heart rate. A heart rate of 81 bpm or higher is determined to indicate a user is in a stressed state. A heart rate of 81 bpm to 99 bpm is assigned a stress level of 1, and a heart rate of 100 bpm or higher is assigned a stress level of 2. When the user is determined to be in a stress level of 1, the generator outputs a carrier wave containing 4 kHz to 5 kHz. When the user is determined to be in a stress level of 2, the generator outputs a carrier wave containing 0.1 kHz to 1 kHz and 4 kHz to 5 kHz. When the interference wave generated by two or more carrier waves indicates a stressed state, it induces muscle contractions that match the user's pre-measured normal heart rate, guiding the user's heart rate back to normal. When the user's normal heart rate is below 65 bpm, the frequency of the interference wave is set to 65 bpm. When the user's normal heart rate is above 80 bpm, the frequency of the interference wave is set to 80 bpm. When the user's heart rate returns to normal, the generation of the interference wave is stopped.

[0168] Stress levels can also be determined from information acquired by an odor sensor. When the odor sensor detects a specific substance or a change in odor, it determines the stress level as 2, regardless of heart rate. For example, the specific substances are two compounds consisting of dimethyl trisulfide and allyl mercaptan, and the detection sites are areas where sweat glands and apocrine glands are located. Table 1 shows the relationship between the presence or absence of detection of the above compounds, the range of heart rate values, and stress levels.

[0169] [Table 1]

[0170] (A stimulation method that can achieve tactile effects and effects on the autonomic nervous system other than muscle stimulation) By setting the frequency of the interference wave to 100 Hz to 1 kHz, effects other than muscle stimulation can be achieved. The sensation of stimulation can be controlled by the amplitude and frequency, but also by the selection of the electrodes to which current is applied. Three or more electrodes can be selected, with two or more pairs selected. For example, if the first, second, third, fourth, fifth, and sixth electrode pairs are selected from 12 electrodes, switching the activated electrode pairs over time, such as between the first and second electrode pairs, the third and fourth electrode pairs, and the fifth and sixth electrode pairs, can be expected to produce a sensation similar to that of a massage on the surface of the skin.

[0171] (Calibration method) A specified voltage is applied to the cosmetics used in combination, the current value is measured, and the electrical resistance value of the cosmetics is calculated. The resistance value of the cosmetics can be determined by connecting to a server via the device's communication device, an external device, or a smartphone app, and referencing the electrical resistance value from a pre-stored cosmetics list, or the user can directly input the electrical resistance value. A specified voltage is applied to the user, the current value is measured, and muscle mass and human body electrical resistance are calculated. Muscle mass and human body resistance can also be calculated based on physical information entered by the user. Physical information includes facial shape, type, color, skin concerns, and skin problems.

[0172] (Muscle cooling) If the temperature of the target muscle rises above the expected level, the epidermis will absorb heat. Heat absorption can be achieved by air cooling, contact with a low-temperature substance, contact with a heat sink, or by applying a volatile component to utilize the heat of vaporization.

[0173] [Electrode placement and device configuration that can apply an appropriate current to induce muscle contraction regardless of individual differences in the user (e.g., individual differences in nerves, muscles, lymph nodes, blood vessels, etc.)] (Multiple electrodes placed) Two electrodes are selected from five or more electrodes to form three or more electrode pairs, each outputting two or more different carrier waves. Therefore, by interfering with each of the multiple carrier waves emitted from multiple electrode pairs, multiple interference waves can be generated, allowing targeted muscle contraction regardless of the internal nerve distribution without moving the device on the skin. For example, if two electrode pairs with no overlapping electrodes are selected from six electrodes, a first carrier wave will be output from the first electrode pair, and a second carrier wave will be output from the second and third electrode pairs. The first carrier wave will interfere with the second carrier wave, generating two interference waves.

[0174] (Move the electrode) Furthermore, for example, as a means for generating multiple interference waves, the first electrode pair may be moved and rotated by motor control to change the positional relationship between the second electrode pair and the third electrode pair, thereby moving the interference wave generation position. To make it easier for the first electrode pair to be moved by the motor, the electrodes should have a shape that provides low contact resistance with the skin, and are preferably approximately dome-shaped.

[0175] (Move unit) As a method for adjusting the position where interference waves are generated other than by electrode placement, the head of the device on which the electrodes are installed may be moved and rotated. To make it easier to move the head using a motor installed in the device, the shape of the electrodes should be such that there is little contact resistance with the skin, and preferably they are approximately dome-shaped.

[0176] (Rotate the unit) Alternatively, the interference wave generation position may be changed by the user adjusting the device's installation position without using a motor. For example, the head unit's exterior has a two-layer structure, with the inner second exterior being rotatable relative to the outer first exterior. The first exterior's position relative to the skin is fixed by the device body, while the second exterior is rotatable 360 degrees in increments of 1 to 90 degrees using a rotation adjustment mechanism. The center of rotation of the second exterior is different from the interference wave generation position, and by rotating the second exterior, the interference wave generation position can be adjusted on a circle centered around the center of rotation of the second exterior. The head unit may be detachable from the device body, allowing the user to freely change its fixed position. The head unit and device body are connected by mechanical fitting, magnetic force, or screw fastening.

[0177] Table 2 shows an example of the numerical ranges of the setting values of various parameters related to the carrier wave in relation to the carrier wave of the interference wave EMS described above. If no special numerical ranges are set in relation to the various embodiments described above, the carrier wave output unit may determine the waveform patterns of the first signal and the second signal so that a carrier wave having the following characteristics is output.

[0188] [Table 7]

[0189] Table 8 shows an example of the relationship between the location where interference waves are generated and the appropriate depth inside the body in relation to interference wave EMS.

[0190] [Table 8]

[0191] In relation to interference wave EMS, the electrode spacing may be 1 to 10 cm, allowing the depth of stimulation to be adjusted to 0.5 to 6 cm inside the body. The number of electrodes may be 3 to 80.
