(1) First Embodiment The first embodiment will be described.

(1-1) Configuration of White Hair Care Device The configuration of the gray hair care device of the first embodiment will be described. FIG. 1 is a schematic view showing the configuration of the white hair care device of the first embodiment. FIG. 2 is a diagram illustrating a configuration of an ultrasonic vibrator among the white hair care devices of the first embodiment.

The white hair care device 1 of FIG. 1 is configured to provide ultrasonic-based white hair care to the user's head (eg, scalp, hair (including hair roots, the same applies hereinafter), or a combination thereof).

As shown in FIG. 1, the gray hair care device 1 includes a storage device 11, a processor 12, an input / output interface 13, a communication interface 14, and a plurality of ultrasonic vibrators 15.

The storage device 11 is configured to store programs and data. The storage device 11 is, for example, a combination of a ROM (Read Only Memory), a RAM (Random Access Memory), and a storage (for example, a flash memory or a hard disk).

The program includes, for example, the following program.
-OS (Operating System) program-Driver application program for controlling the ultrasonic transducer 15-Application program for executing information processing

The data includes, for example, the following data.
-Database referenced in information processing-Data obtained by executing information processing (that is, the execution result of information processing)

The processor 12 may be configured to realize the function of the controller of the white hair care device 1 by activating the program stored in the storage device 11. The processor 12 is an example of a computer.

The processor 12 controls a plurality of ultrasonic vibrators 15. Specifically, the processor 12 controls a plurality of ultrasonic vibrators 15 so as to radiate ultrasonic waves.

The input / output interface 13 is configured to acquire a signal (for example, a user's instruction) from an input device connected to the white hair care device 1 and output a signal to an output device connected to the white hair care device 1. NS.
The input device is, for example, a keyboard, a pointing device, a touch panel, a remote controller, a push button, a switch, or a combination thereof.
The output device is, for example, a display, a speaker, a vibration device, an optical guide, or a combination thereof.

The communication interface 14 is configured to control communication between the gray hair care device 1 and an external device (eg, a server, a user device (eg, a smartphone, a wearable device)) (not shown).

As shown in FIG. 2A, the plurality of ultrasonic vibrators 15 are arranged on the vibrator board 16 in an array, for example. The plurality of ultrasonic vibrators 15 are configured to be driven (that is, vibrate) according to the control of the processor 12.

As shown in FIG. 2B, the oscillator board 16 includes a paraboloid (an example of a "concave curved surface") 16S. A plurality of ultrasonic vibrators 15 are arranged on the paraboloid surface 16S.

(1-2) Outline of the first embodiment The outline of the first embodiment will be described. FIG. 3 is an explanatory diagram of an outline of the first embodiment.

The processor 12 drives, for example, a plurality of ultrasonic transducers 15 at the same time. Each of the driven ultrasonic vibrators 15 emits an ultrasonic beam in a direction (Z direction) orthogonal to the radiation plane (XY plane) of the ultrasonic vibrator 15. As shown in FIG. 3, the ultrasonic beams (that is, focused ultrasonic waves) radiated from the plurality of ultrasonic transducers 15 at the same time are focused on the focal point FP determined by the shape of the paraboloid 16S. Therefore, when the treatment site of the user U (for example, the scalp, hair, or a combination thereof) is located at the focal point FP, the ultrasonic beams emitted from the plurality of ultrasonic transducers 15 at the same time, for example, are the treatment site of the user U. Acoustic radiation pressure by focused ultrasonic waves can be applied non-contactly. Due to the applied acoustic radiation pressure, the treatment site of the user U receives a pressing stimulus in the Z direction without contacting any ultrasonic vibrator 15.

The processor 12 intermittently drives a plurality of ultrasonic vibrators 15 at a predetermined vibration frequency (for example, 10 Hz). Specifically, the processor 12 drives the plurality of ultrasonic transducers 15 over the first period, and does not drive the plurality of ultrasonic transducers 15 over the second period following the first period. The acoustic radiation pressure that pressed the treatment site of the user U in the first period disappears in the second period. When the acoustic radiation pressure disappears, the restoring force due to the elasticity of the scalp acts on the treatment site of the user U. That is, by repeating the first period and the second period, acoustic radiation pressure is intermittently applied to the treatment site of the user U, and the treatment site vibrates without contacting any ultrasonic vibrator 15. It vibrates at a frequency. When the user's scalp vibrates, pigment cells (melanocytes) are activated. As a result, the effect of improving the white hair of the user can be obtained.

As an example, the processor 12 may intermittently apply acoustic radiation pressure to the treatment site of the user U by radiating focused ultrasonic waves modulated at a predetermined vibration frequency from a plurality of ultrasonic vibrators 15. .. An example of modulation is Amplitude Modulation (AM). The processor 12 applies a PWM (Pulse Width Modulation) modulated drive signal to the plurality of ultrasonic transducers 15, so that the plurality of ultrasonic transducers 15 emit amplitude-modulated focused ultrasonic waves. good.

(1-3) Outline of the experiment The outline of the experiment will be described. The inventors hypothesized that ultrasonic irradiation would improve white hair, and conducted the following experiments for verification.

In this experiment, the inventors performed a total of 6 white hair care treatments on a subject having both white hair and black hair at a frequency of 1 to 2 times a week for 1 month. In each treatment, the subject wore a swimming cap having a hole with a diameter of about 3 cm in the portion corresponding to the forehead, and the portion exposed from the hole was used as the treatment site. That is, although there may be an error due to how the subject wears the swimming cap, the treatment site is generally constant in each treatment. The focal length of the white hair care device used for each treatment was set to 100 mm. The gray hair care device was positioned so that the focus was on the skin surface (that is, the scalp) at the treatment site, and ultrasonic waves with an output of 160 dB were AM-modulated with a 10 Hz square wave and emitted. The execution time of each treatment, that is, the irradiation time of ultrasonic waves was set to 60 minutes.

The inventors performed close-up observation using a commercially available microscope camera at the timing before and after the multiple treatments. Since it is difficult to track and observe specific hair at each treatment, in each observation, by taking multiple photographs while changing the angle within the range of the hole of the swimming cap, the hair at the treatment site can be observed. I decided to capture the tendency of color. The observation after the 6th treatment also included the non-treatment site (top of the head).

In the observation performed before the first treatment, black hair (black hair) from the root to the tip of the hair and white to transparent hair (white hair) from the root to the tip of the hair could be confirmed at the treatment site.

In close-up observations performed after the 6th treatment, apart from black hair and white hair, hair that was white on the tip side but black on the root side (mottled darkening) was frequently confirmed at the treatment site. It can be said that the hair colored white on the tip side but black on the root side indicates that a part of the white hair seen in the close-up observation performed before the first treatment is regaining its original color.

Furthermore, in the close-up observation performed after the 6th treatment, apart from the white hair, which is good for black hair even in the non-treatment area, the hair that was white on the tip side but blackened on the root side (mottled darkening) was compared with the treatment site. It was confirmed that the frequency was low.

In this experiment, it took about 20 days from the first treatment to the appearance of the effect of the treatment (that is, hair that was white on the tip side but black on the root side began to be seen). The part of the hair that is buried in the skin is called the hair root. At the lower end of the hair root, there is a part called a hairball that produces hair. The newly created hair from the hairball pushes the hair toward the surface of the skin. Since the length of the hair root is about 3 mm and the elongation rate of the hair is about 0.3 mm / day, the change occurring in the hairball begins to appear outside the skin about 10 days after the occurrence of the change. Hair needs to grow further to be able to see changes in the hair bulbs that appear outside the skin. Therefore, it can be said that it took about 20 days before the effect of the first treatment became visible from the viewpoint of the length of the hair root and the growth rate of the hair.

Hair bulbs have pigment cells called melanocytes. It is known that black hair grows when melanocytes are active, and white hair grows when resting or missing. According to previous studies, 20% of melanocytes in white hair bulbs are dormant, and 80% of melanocytes are deficient. There is also a theory that the rate of melanocyte rest is higher than 20% in young white hair bulbs.

It is considered that the coloring of the roots of the white hair in this experiment was due to the reactivation of melanocytes that had been dormant.

(1-4) White Hair Care Treatment Treatment The white hair care treatment treatment of the first embodiment will be described. FIG. 4 is a flowchart of the white hair care treatment process of the first embodiment.

As shown in FIG. 4, the white hair care device 1 executes the reception of the start instruction (S10).
Specifically, the processor 12 receives a start instruction from the user U via the input / output interface 13 or the communication interface 14.

After step S10, the white hair care device 1 performs treatment support (S11).
Specifically, the processor 12 executes at least one of the following.
-Process to guide the position of the focus FP to user U-Process to play the content to be viewed by user U during the white hair care treatment process-Pass-through process (that is, omission of this step S11)

After step S11, the gray hair care device 1 executes the control (S12) of the ultrasonic transducer.
Specifically, the processor 12 intermittently drives the plurality of ultrasonic vibrators 15 at a predetermined vibration frequency until a predetermined treatment time (for example, about 2 minutes to 60 minutes) is completed. As an example, the processor 12 may intermittently apply acoustic radiation pressure to the treatment site of the user U by radiating focused ultrasonic waves amplitude-modulated at a predetermined vibration frequency from a plurality of ultrasonic vibrators 15. good. The processor 12 drives, for example, a plurality of ultrasonic vibrators 15 at the same time. That is, the drive timings of the plurality of ultrasonic vibrators 15 are the same.

The arm 155 includes a physical guide 155a that physically guides the position of the focal point FP to the user U. The physical guide 155a stabilizes the positional relationship between the mesh cover 151 and the treatment site of the user U by fixing the white hair care device 150 to the user's head (an example of "a part of the body"). The treatment site of U stays near the focal point FP. That is, the physical guide 155a can physically guide the treatment site of the user U to the focal point FP. The physical guide 155a may be provided with an adjuster to adapt to individual differences in the shape and size of the user's head. Further, since the physical guide 155a fixes the white hair care device 150 to the head of the user U, the user U can move during the treatment.

The physical guide 167 is a protrusion that is arranged on the mesh cover 161 and extends in the Z direction from the mesh cover 161. A nozzle 167a is attached to an end (hereinafter, simply referred to as a tip) of the physical guide 167 opposite to the mesh cover 161. The size of the physical guide 167 in the Z direction is determined according to the position of the focal point FP. The physical guide 167 is configured to physically guide the position of the focal point FP to the user U. Specifically, the physical guide 167 physically guides the treatment site of the user U to the focal point FP by contacting the user U.

As an example, the size of the physical guide 167 in the Z direction may be determined so that the nozzle 167a coincides with the position of the focal point FP. As a result, the user U can easily position the treatment site near the focal point FP by adjusting the position and posture of the white hair care device 160 so that the nozzle 167a hits the treatment site.

The nozzle 167a is attached to the tip of the physical guide 167. The nozzle 167a is configured to be capable of discharging the hair care agent. Nozzle 167a applies a hair care agent to at least one of User U's scalp and hair before, during, and after the procedure.

The nozzle 167a includes a cartridge that holds a hair care agent to be discharged from the nozzle 167a. Holding the hair care agent in the cartridge makes it easier to use or replenish the hair care agent properly, and makes it easier to keep the hair care agent hygienic without the trouble of cleaning, as compared with the case where the hair care agent is held in the tank. There are advantages such as.

As described above, the white hair care device 1 of the first embodiment includes a plurality of ultrasonic vibrators 15 on the parabolic surface 16S of the vibrator board 16. Therefore, according to the white hair care device 1, for example, by driving a plurality of ultrasonic vibrators 15 at the same time, the ultrasonic beam can be focused on the focal point FP determined by the shape of the paraboloid surface 16S. That is, the white hair care device 1 does not need to individually control the drive timing of the ultrasonic vibrator 15. When the user U adjusts the treatment site to the focal point FP, the treatment site can receive a pressing stimulus by the acoustic radiation pressure by the ultrasonic beam without contacting (that is, non-contacting) any ultrasonic vibrator 15. .. In particular, by intermittently driving a plurality of ultrasonic vibrators 15, acoustic radiation pressure is intermittently applied to the treatment site of the user U, and the treatment site is in contact with any of the ultrasonic vibrators 15. It vibrates at the above vibration frequency. When the scalp of the user U vibrates, pigment cells (melanocytes) are activated.

(2) Second Embodiment The second embodiment will be described.

(2-1) Configuration of White Hair Care Device The configuration of the gray hair care device of the second embodiment will be described. FIG. 12 is a schematic view showing the configuration of the white hair care device of the second embodiment. FIG. 13 is a diagram illustrating a configuration of an ultrasonic vibrator among the white hair care devices of the second embodiment.

As shown in FIG. 12, the gray hair care device 1A includes a storage device 11, a processor 12, an input / output interface 13, a communication interface 14, a plurality of ultrasonic vibrators 15, and an image sensor 18.

The image sensor 18 is connected to the processor 12 via the input / output interface 13. The image sensor 18 may be a monocular camera, a stereo camera, or a ToF (Time of Flight) camera. The image sensor 18 is configured to generate an image (moving image or still image) by, for example, photographing the user U in response to an instruction from the processor 12. The image is, for example, RGB data or RGBD data.

As shown in FIG. 13A, the plurality of ultrasonic vibrators 15 are arranged on the vibrator board 16A, for example, in an array. The plurality of ultrasonic vibrators 15 are configured to be driven (that is, vibrate) according to the control of the processor 12.

As shown in FIG. 13B, the oscillator board 16A includes a flat surface 16SA. A plurality of ultrasonic vibrators 15 are arranged on the surface 16SA.

(2-2) Outline of the second embodiment The outline of the second embodiment will be described. FIG. 14 is an explanatory diagram of an outline of the second embodiment.

The processor 12 drives the plurality of ultrasonic vibrators 15 with a time difference according to the position of the focal point FP. Each of the driven ultrasonic vibrators 15 emits ultrasonic beams having different phases from each other in a direction (Z direction) orthogonal to the radiation plane (XY plane) of the ultrasonic vibrator 15. As shown in FIG. 14, the ultrasonic beams (that is, focused ultrasonic waves) radiated from the plurality of ultrasonic transducers 15 with a time lag are focused on the focal point FP. Therefore, when the treatment site of the user U (for example, the scalp, hair, or a combination thereof) is located at the focal point FP, the ultrasonic beams radiated from the plurality of ultrasonic transducers 15 with a time lag are generated by the user U. Acoustic radiation pressure by focused ultrasonic waves can be applied to the treatment site in a non-contact manner. Due to the applied acoustic radiation pressure, the treatment site of the user U receives a pressing stimulus in the Z direction without contacting any ultrasonic vibrator 15.

The processor 12 intermittently drives a plurality of ultrasonic vibrators 15 at a predetermined vibration frequency (for example, 10 Hz). Specifically, the processor 12 drives the plurality of ultrasonic transducers 15 over the first period, and does not drive the plurality of ultrasonic transducers 15 over the second period following the first period. The acoustic radiation pressure that pressed the treatment site of the user U in the first period disappears in the second period. When the acoustic radiation pressure disappears, the restoring force due to the elasticity of the scalp acts on the treatment site of the user U. That is, by repeating the first period and the second period, acoustic radiation pressure is intermittently applied to the treatment site of the user U, and the treatment site vibrates without contacting any ultrasonic vibrator 15. It vibrates at a frequency. When the user's scalp vibrates, pigment cells (melanocytes) are activated. As a result, the effect of improving the white hair of the user can be obtained.

As an example, the processor 12 may intermittently apply acoustic radiation pressure to the treatment site of the user U by radiating focused ultrasonic waves modulated at a predetermined vibration frequency from a plurality of ultrasonic vibrators 15. .. An example of modulation is Amplitude Modulation (AM). The processor 12 applies a PWM (Pulse Width Modulation) modulated drive signal to the plurality of ultrasonic transducers 15, so that the plurality of ultrasonic transducers 15 emit amplitude-modulated focused ultrasonic waves. good.

(2-3) White Hair Care Treatment Treatment The white hair care treatment treatment of the second embodiment will be described. FIG. 15 is a flowchart of the white hair care treatment process of the second embodiment.

As shown in FIG. 15, the white hair care device 1A executes the reception of the start instruction (S10) (FIG. 4).
Specifically, the processor 12 receives a start instruction from the user U via the input / output interface 13 or the communication interface 14.

After step S10, the gray hair care device 1A executes the acquisition of reference information (S21).
Specifically, the processor 12 acquires information (reference information) to be referred to for determining the position of the focal point FP.
In the first example of the acquisition of reference information (S21), the processor 12 instructs the image sensor 18 to take a picture and receives the image of the user U.
In the second example of acquiring reference information (S21), the processor 12 receives an operation of the user U (for example, an operation indicating at least one of the absolute coordinates of the focal point, the moving direction with respect to the default coordinates, and the moving amount). .. The user's operation may indicate the absolute coordinates of the position that the user U wants to set as the focus, or at least one of the movement direction and the amount of movement from the predetermined initial focus to the position that the user U wants to set as the focus. There may be.

After step S21, the gray hair care device 1A performs focus determination (S22).
Specifically, the processor 12 determines the position of the focal point FP based on the reference information received in step S21.
In the first example of focus determination (S22), the gray hair care device 1A identifies the relative position of the treatment site with respect to the plurality of ultrasonic transducers 15 by analyzing the image as reference information. The processor 12 determines the position of the focal point FP with reference to the specified relative position.
In the second example of the focus determination (S22), the gray hair care device 1A determines the position of the focus FP according to the content of the operation as reference information.
By determining the focus (S22), the user U can adjust the focus FP to the treatment site of the user U instead of aligning the treatment site with the position of the focus FP. The processor 12 calculates the drive timing of each of the plurality of ultrasonic transducers 15 according to the determined position of the focal point FP.

After step S22, the white hair care device 1A performs treatment support (S11A).
Specifically, the processor 12 executes at least one of the following.
-Shooting of the treatment site of the user U-Judgment of the state of the user U based on the shot image-The treatment parameter (for example, a plurality of ultrasonic vibrators) that specifies the treatment content with reference to the judged state of the user U. The focused FP determined in step S22 with reference to the state of the user U that has been processed / determined to determine (at least one of the radiation sound pressure of 15 and the vibration frequency applied to the treatment site of the user U and the treatment time). Processing to change the position (for example, processing to change the position of the focal point FP determined in step S21 to a position with gray hair)
-A process of guiding the position of the focal point FP determined in step S22 to the user U-A process of reproducing the content to be viewed by the user U during the white hair care treatment process-A pass-through process (that is, omission of this step S11A)

After step S11A, the gray hair care device 1A executes control of the ultrasonic transducer (S12A).
Specifically, the processor 12 intermittently drives the plurality of ultrasonic vibrators 15 at a predetermined vibration frequency until a predetermined treatment time (for example, about 2 minutes to 20 minutes) is completed. As an example, the processor 12 may intermittently apply acoustic radiation pressure to the treatment site of the user U by radiating focused ultrasonic waves amplitude-modulated at a predetermined vibration frequency from a plurality of ultrasonic vibrators 15. good. The processor 12 determines the drive timing for each of the plurality of ultrasonic vibrators 15 according to the determination in step S22. As a result, the ultrasonic waves radiated from the plurality of ultrasonic transducers 15 have a phase difference. As a result, focused ultrasonic waves focused on the focal point according to the phase difference are radiated from the plurality of ultrasonic transducers 15.
