[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the drawings are merely examples, and the present invention is not limited to those shown in the drawings. For example, the size, number, and arrangement of each component constituting the facial beauty device, the example of wearing the facial beauty device, the flowchart showing the operation example of the facial beauty device, and the current waveform are merely examples, and the present invention is not limited to these. Note that in the following description, the front-to-back direction, left-to-right direction, and up-to-down direction are defined based on the orientation of the user using the facial beauty device 1.

[0016] <Structure of facial beauty device> 1 and 2 are diagrams showing the appearance of a facial beauty device 1 according to this embodiment, with FIG. 1 being a perspective view of the facial beauty device 1, FIG. 2(a) being a front view of the facial beauty device 1, and FIG. 2(b) being a right side view of the facial beauty device 1. As shown in these figures, the facial beauty device 1 is an EMS (Electrical Muscle Stimulation) device shaped like headphones. An EMS device is a device that applies electrical stimulation to muscles to forcibly contract them. The facial beauty device 1 comprises a pair of pads 10, one on each side, and a connecting portion 11 that connects the pair of pads 10. As will be described in more detail below, the user presses the pads 10 against their face so as to cover their cheeks and the surrounding area, and receives electrical stimulation via electrodes provided on the pads 10.

[0017] The connecting portion 11 is a band member that curves and extends to cover the user's head or neck. The connecting portion 11 includes a headband 12 that covers the user's head, a pair of slider bands 13 extending from both ends of the headband 12, and a pair of housings 14 connected to the slider bands 13. A power supply unit 30 that supplies driving power to the facial beauty device 1 and a communication unit 60 that wirelessly communicates with external devices are built into, for example, the end of the headband 12. Note that instead of the headband 12 that covers the user's head, a neckband that covers the back of the user's neck may be used. Furthermore, the positions of the power supply unit 30 and the communication unit 60 are not limited to within the headband 12; they may be installed in the pad unit 10 or supplied from an external power source. In other words, the headband 12 may be unnecessary as long as a driving current can be supplied to the electrodes provided on each pad unit 10.

[0018] The slider band 13 is a member that is disposed so as to be able to be housed inside the headband 12, and whose length can be adjusted by being pulled out from the headband 12 according to the position of the pad portion 10 selected by the user.

[0019] The housing 14 is connected to the lower end of the slider band 13, accommodates the lower end, and holds the pad portion 10. The pad portion 10 is connected to the housing 14 via a support shaft 15. The support shaft 15 is provided inside the housing 14 and supports the pad portion 10 rotatably relative to the housing 14. Note that while the housing 14 is shown to be rectangular in shape in FIG. 2, its shape is not limited to a rectangular shape as long as it contains the support shaft 15 and accommodates the lower end of the slider band 13. Also, the example in FIGS. 1 and 2 shows the slider band 13 in an extended state, and the slider band 13 can be completely accommodated in the housing 14 when the facial beauty device 1 is stored, for example.

[0020] Next, the pad section 10 will be described with reference to Fig. 3. Fig. 3(a) is a diagram showing the shape of the pad section 10 as viewed from the front, and Fig. 3(b) is a diagram showing the shape of the pad section 10 as viewed from the side.

[0021] The pad 10 is provided with multiple electrodes, each consisting of a positive electrode (+) 20P and a negative electrode (-) 20M, which are in close contact with the user's face to provide electrical stimulation. Hereinafter, the positive electrode 20P and the negative electrode 20M are collectively referred to as electrodes 20. In FIG. 3(a), one pair of positive and negative electrodes is provided on the front side of the pad 10, and another pair of positive and negative electrodes is provided on the rear side of the pad 10. The arrangement of the electrodes 20 can be changed as desired; for example, only one pair of positive and negative electrodes (+) and electrodes (-) may be provided, or three or more pairs may be provided.

[0022] The pad 10 has a substantially rectangular shape with two of its four sides curved. The front edge of the pad 10, located at the front, is curved so that the center in the up-down direction protrudes rearward. The rear edge of the pad 10, located at the rear, is curved so that the center in the up-down direction protrudes rearward. The shape of the pad 10 is not limited to this, and it may be, for example, circular.

[0023] When applying electrical stimulation to the face (i.e., passing an electric current through the face), it is preferable to apply a conductive gel to the surface of the pad unit 10 that comes into contact with the face, or to interpose a conductive gel pad (hereinafter simply referred to as a "gel pad") between the pad unit 10 and the face. For example, in the case of a gel pad, the conductive gel may be in the form of a sheet of a predetermined thickness, and may have two conductive fasteners (e.g., dowels of a spring hook) that function as positive and negative electrodes, respectively. The pad unit 10 is provided with two conductive fasteners (gel pad springs) that function as positive and negative electrodes, respectively, and by fastening the dowels of the gel pad to the springs of the pad unit 10, the gel pad is fixed to the pad unit 10 and electricity can be passed through the gel pad.

[0024] <How to use the facial beauty device> Next, we will explain how to use the facial beauty device 1. Figures 4(a) and 4(b) are diagrams showing examples of how to use the facial beauty device 1.

[0025] In the example of Figure 4(a), the user uses the facial beauty device 1 by wearing the headband 12 on the head so that it covers the top of the head. This causes the pad portion 10 to cover at least a portion of the orbicularis oculi muscle, the zygomatic major muscle, and the buccinator muscle. By operating the facial beauty device 1 in this manner, it is possible to stimulate these muscles (orbicularis oculi muscle, zygomatic major muscle, and buccinator muscle) of the user.

[0026] Furthermore, by extending the slider band 13 from the state shown in FIG. 4(a) and rotating the pad unit 10 relative to the slider band 13 around the support shaft 15, the facial beauty device 1 can be worn in the state shown in FIG. 4(b). This causes the portion of the pad unit 10 where the electrodes 20 are provided to contact the user's face, which is located on the inside of the eye center in the left-right direction. At this time, the pad unit 10 covers not only the orbicularis oculi muscle, zygomaticus major muscle, and buccinator muscle, but also at least a portion of the orbicularis oris muscle and levator labii superioris muscle. This allows stimulation from the electrodes 20 to be applied to a wider area of ​​the face.

[0027] As described above, by applying electrical stimulation to the user's face with the facial beauty device 1, the facial muscles of the user can be tightened (pumped up), eliminating sagging cheeks and the like, and the effect of making the face look smaller can be expected. Note that the method of using the facial beauty device 1 is not limited to that shown in the figure. The facial beauty device 1 can also be used on the temples, shoulders, neck, etc., for example.

[0028] <Example of facial beauty device configuration> 5 is a block diagram showing an example configuration of the facial beauty device 1. The facial beauty device 1 includes, as hardware components, a pad unit 10, electrodes 20, a power supply unit 30, an acquisition unit 50, a communication unit 60, an operation unit 70, a memory 80, and a control unit 100. The components of the facial beauty device 1 are connected to each other via a bus and are controlled by the control unit 100.

[0029] The control unit 100 is a processor having the function of controlling each part of the facial beauty device 1. The control unit 100 may be a microcontroller (Micro Controller Unit: MCU) including a central processing unit (CPU), a microcomputer, or the like. The control unit 100 realizes the functions of the facial beauty device 1 by executing various programs stored in the memory 80. The control unit 100 includes a generation unit 110 as a software configuration.

[0030] The pad unit 10 and the electrode 20 are as described above, and although only one is shown in Fig. 5 for simplicity, the facial beauty device 1 has two pad units 10. Furthermore, the electrode 20 may be provided in multiple pairs, each consisting of a positive electrode and a negative electrode, on the pad unit 10.

[0031] The power supply unit 30 may be a primary battery such as a lithium battery, or a secondary battery such as a lithium ion battery. When the power supply unit 30 is realized by a secondary battery, the facial beauty device 1 may be provided with a charging terminal that allows the power supply unit 30 to be charged. Furthermore, multiple power supply units 30 may be provided depending on the circuit configuration. Furthermore, the power supply unit 30 may be configured to be detachable from the facial beauty device 1.

[0032] The generator 40 generates a sinusoidal AC current having a predetermined frequency to be applied to the electrodes from the power supplied by the power supply 30. That is, the generator 40 may provide the function of an inverter circuit that converts DC current into AC current. This will be explained using FIG. 6.

[0033] FIG. 6 is a schematic diagram illustrating the generation of a composite AC current according to one embodiment of the present invention. Note that the diagram is schematic and not precise. Here, the term "composite AC current" refers to a wave obtained by amplitude-modulating a fundamental wave having a certain waveform with another modulating wave. FIG. 6(a) shows an example of a first AC current W1 having a first frequency. The first frequency may be, but is not limited to, 10 to 11 kHz. FIG. 6(b) shows an example of a second AC current W2 having a second frequency. The second frequency is lower than the first frequency and may be, but is not limited to, 2 to 20 Hz or 40 to 50 Hz. The generator 40 generates a composite AC current W3 by amplitude-modulating the first AC current W1 with the second AC current W2.

[0034] FIG. 6(c) shows an example of a composite AC current W3. The control unit 100 applies the composite AC current to the electrode 20. In other words, the user is provided with a relatively high-frequency AC current of approximately 10 kHz, with its intensity gradually changing. Generally, EMS devices using low frequencies of 20 Hz to 100 Hz have high skin resistance due to their low frequency, making them more susceptible to pain and preventing electrical stimulation from penetrating deep into the skin. On the other hand, EMS devices using high frequencies of 10 kHz or higher have finer waves than low frequencies, resulting in weaker skin resistance and less pain, allowing electrical stimulation to penetrate deeper into the subcutaneous tissue. The facial beauty device 1 according to one embodiment of the present invention combines high-frequency and low-frequency currents, as shown in FIG. 6(c), and provides the combined current to the user, thereby stimulating deeper muscles and causing less pain than EMS devices using low frequencies of 20 Hz to 100 Hz.

[0035] The first amplitude Ec, which is the amplitude value of the first AC current, may be greater than the second amplitude Es, which is the amplitude value of the second AC current. This allows the minimum amplitude Emb of the composite AC current to be equal to or greater than zero. Generally, EMS devices that use pulse current tend to cause pain due to the amplitude rising suddenly from zero. In contrast, one embodiment of the present invention has the advantage of not causing pain because the amplitude is never set to zero and high-frequency current is continuously applied. Although high-frequency generation is prone to instability, the value of the first frequency does not need to be constant and may vary slightly.

[0036] Returning to the explanation of FIG. 5, the communication unit 60 has a function of communicating with a device external to the facial beauty device 1. The communication unit 60 may transmit information specified by the control unit 100 to the external device. The information transmitted to the outside may be information indicating the control content performed by the facial beauty device 1 (for example, what voltage and how long it was driven). This information indicating the control content may be transmitted to an external device (for example, a user's communication terminal) and displayed on the external device. The communication unit 60 may also receive control commands for controlling the facial beauty device 1 from an external device (for example, the user's communication terminal or the controller of the facial beauty device 1). Note that if communication with an external device is not required, the communication unit 60 is not particularly essential.

[0037] The operation unit 70 accepts input operations from the user of the facial beauty device 1. The operation unit 70 may be provided, for example, as hard keys or soft keys on the headband 12, and may, for example, allow the user to specify the frequency of the current applied to the pad unit 10, the intensity (amplitude value of the current) in multiple stages, or the driving mode (details will be described later). The operation unit 70 may also include a button for starting or stopping the facial beauty device 1. Note that, if operations from an external device are accepted via the communication unit 60, the operation unit 70 may not be present.

[0038] The memory 80 has a function of storing various programs and data for controlling each part of the facial beauty device 1. The memory 80 can be realized by, but is not limited to, a flash memory, as an example. The acquisition unit 50 will be described later.

[0039] <Drive mode> Next, the multiple driving modes of the facial beauty device according to one embodiment of the present invention will be described with reference to Figures 7 and 8. The facial beauty device 1 can operate in multiple driving modes, and a single exercise cycle may be configured by combining multiple driving modes. An exercise cycle may be a combination of intensity and time set to provide an appropriate amount of exercise to the user's muscles. Here, the difference in driving mode is a difference in the first frequency or the second frequency described above, and the generator 110 changes at least one of the first frequency and the second frequency according to the multiple driving modes to generate the above-mentioned composite AC current.

[0040] Figure 7 shows an example of a composite AC current when the frequency of the first frequency, i.e., the frequency band of high frequencies, is changed. The frequency of the second frequency is the same in the first and second modes, but the frequency of the first frequency in the second mode is higher than that in the first mode. Compared to the composite AC current W3 in the first mode, the composite AC current W4 in the second mode penetrates electrical stimulation deeper into the muscles.

[0041] 8 shows an example of a composite AC current when the frequency of the second frequency, i.e., the low-frequency band, is changed. The first frequency is the same in the first and third modes, but the second frequency is higher in the third mode than in the first mode. Compared to the composite AC current W3 in the first mode, the composite AC current W5 in the third mode electrically stimulates the muscles at a higher frequency.

[0042] 7 and 8 show a case where the switching to a different mode is performed immediately, but this is not limiting. That is, the switching to a different mode may be performed in stages. For example, when switching the frequency from 2 Hz to 20 Hz, the switching may be performed in stages such as from 2 Hz to 5 Hz, from 5 Hz to 10 Hz, and from 10 Hz to 20 Hz. Furthermore, the switching of the amplitude value may also be performed in stages.

[0043] There may be a driving mode in which both the first frequency and the second frequency are changed, a driving mode in which the amplitude of the first AC current or the second AC current is changed, or a driving mode in which both the frequency and the amplitude are changed.

[0044] Here, the acquisition unit 50 acquires the resistance value between the electrodes 20 when the pad unit 10 is attached to the user's face. The generation unit 110 may then change at least one of the first frequency and the second frequency according to the resistance value. The resistance value can be used to measure the user's facial muscle mass, allowing electrical stimulation to be provided according to the user's condition. An exercise cycle of a drive mode according to muscle mass may be preset and stored in the memory 80. This allows an appropriate exercise cycle to be provided in response to changes in muscle mass that may occur as the user continues to use the facial beauty device 1.

[0045] Furthermore, the generating unit 110 may change at least one of the first amplitude Ec of the first AC current and the second amplitude Es of the second AC current, according to the resistance value acquired by the acquiring unit 50. This makes it possible to provide electrical stimulation by a current with a strength according to the muscle mass of the user.

[0046] The communication unit 60 may wirelessly communicate with an external control terminal (e.g., a user's communication terminal or an external controller) that accepts the setting of at least one of the first frequency, second frequency, first amplitude, and second amplitude values ​​described above. The generation unit 110 then generates a composite AC current based on the values ​​set in the control terminal. This allows for more detailed setting of the drive mode according to the user's preferences.

[0047] <Operation> Next, an example of the operation of the facial beauty device 1 will be described with reference to Fig. 9. Fig. 9 is a flowchart showing an example of the operation of the facial beauty device 1 according to one embodiment.

[0048] First, when the facial beauty device 1 is activated, the power supply unit 30 starts to supply electricity to the electrode 20 according to a preset driving cycle (step S11). For simplicity, the driving cycle will be described as a combination of the first mode and the second mode twice in this order, and the first mode and the second mode have different frequencies in the high-frequency band of AC current.

[0049] The generator 110 amplitude-modulates the AC current (high-frequency AC current) having a frequency in the first mode with a modulating AC current (low-frequency AC current) (step S12). Then, the controller 100 applies the generated composite AC current to the electrodes 20 (step S13). After the drive time in the first mode has elapsed, the generator 110 amplitude-modulates the AC current (high-frequency AC current) having a frequency in a second mode different from the first mode with a modulating AC current (low-frequency AC current) (step S14). Then, the controller 100 applies the generated composite AC current to the electrodes 20 (step S15). The controller 100 determines whether or not the operation in a preset drive cycle has ended (step S16). If the operation in the drive cycle has ended, the controller 100 ends the energization (NO in step S16). If the operation in the drive cycle has not ended (YES in step S16), the controller 100 returns to step S12.

[0050] Thus, according to one embodiment of the present invention, an amplitude-modulated composite wave is generated by combining a high-frequency AC current and a low-frequency AC current and applied to the electrodes, thereby stimulating deeper muscles and providing a facial beauty device with minimal pain.

[0051] Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art would easily be able to make various modifications and alterations based on this disclosure. Therefore, it should be noted that these modifications and alterations are within the scope of the present invention. For example, the functions included in each component, step, etc. can be rearranged so as not to cause logical inconsistencies, and multiple components, steps, etc. can be combined into one or divided, or omitted or modified as appropriate as needed. Furthermore, the configurations shown in the above embodiments may be combined as appropriate.

[0052] For example, in the above description, an example was shown in which the headphone-shaped facial beauty device 1 is worn like headphones. However, instead of the facial beauty device 1 itself, only a gel pad connected to the connection terminal of the facial beauty device 1 using a wired cable may be attached to the area where electrical stimulation is to be applied. That is, the spring of the gel pad and the dowel provided on the pad portion 10 of the facial beauty device 1 may be connected by a conductive cable, and current may be supplied to the gel pad from the power supply portion 30 of the facial beauty device 1 via the cable. This increases the degree of freedom in the area of ​​use.

[0053] Furthermore, for example, the skin around the eyes on the face is thinner than the cheeks, so it is preferable to apply electrical stimulation at a different intensity than the cheeks. Therefore, the drive mode (operation cycle) may be automatically switched depending on the area where the pad unit 10 is in contact. For example, the control unit 100 may determine the relative position of the pad unit 10 with respect to the entire facial beauty device 1 when energized (e.g., the headband 12 and the pad unit 10 are approximately aligned in the longitudinal direction as shown in FIG. 4(a), or the pad unit 10 is rotated a predetermined angle relative to the headband 12 as shown in FIG. 4(b)), and drive the device in a preset operation cycle depending on the relative position. Alternatively, the resistance value of each part of the user's body may be measured in advance to set the operation cycle, and the control unit 100 may determine the user's part based on the resistance value measured when energized and drive the device in the operation cycle for that part. The set operation cycle may be stored in memory 80.

[0054] The pad unit 10 may be interchangeable depending on the area to which electrical stimulation is to be applied. For example, the pad unit 10 for the cheeks and the pad unit 10 for the area around the eyes may have different sizes and shapes. The control unit 100 may determine the type of pad unit 10 attached based on the resistance value when connected to the electrodes, and may switch the drive mode depending on the type of pad unit 10.

[0055] In the above description, the method of controlling the current in the facial beauty device 1 is described as the device's processor controlling the current by executing a control program, etc. This may also be achieved by a logic circuit (hardware) or dedicated circuit formed in an integrated circuit (IC (Integrated Circuit) chip, LSI (Large Scale Integration)) or the like in the facial beauty device 1.

[0056] A D / A converter, an oscillator circuit, a PWM (Pulse Width Modulation) circuit, or the like may be used to convert the direct current supplied from the power supply unit 30 into an alternating current.

[0057] The control program may be recorded on a processor-readable recording medium, which may be a "non-transitory tangible medium" such as a tape, disk, card, semiconductor memory, or programmable logic circuit. The control program may be supplied to the processor via any transmission medium capable of transmitting the control program (such as a communications network or broadcast waves). The present invention may also be realized in the form of a data signal embedded in a carrier wave, in which the control program is embodied by electronic transmission.

[0058] The control program can be implemented using, for example, a scripting language such as ActionScript or JavaScript (registered trademark), an object-oriented programming language such as Objective-C or Java (registered trademark), or a markup language such as HTML5, but is not limited to these.
