[0038] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0039] In one embodiment, Figure 1 As shown, an ultrasonic transducer 100 is provided, which includes an acoustic wave emitting assembly 110. The acoustic wave emitting assembly 110 includes a planar acoustic wave emitting device 111 and a focused acoustic wave emitting device 112. The planar acoustic wave emitting device is used to emit planar ultrasonic waves. The focused acoustic wave emitting device 112 includes at least one concave structure 121. The concave structure 121 is used to focus the planar ultrasonic waves emitted by the focused acoustic wave emitting device 112 into focused ultrasonic waves.

[0040] Among them, the sound wave emitting component 110 is used to convert electrical energy into sound energy and emit ultrasonic waves in a specific form and direction, thereby generating and emitting ultrasonic waves. In this embodiment, the sound wave emitting component 110 is divided into two different areas, a planar sound wave emitting device 111 and a focused sound wave emitting device 112. The frequency, intensity, waveform and other parameters of the ultrasonic waves emitted by different sound wave emitting devices can be different. The concave structure 121 is a structural unit with an inwardly concave shape. In this embodiment, the concave structure 121 is arranged on the focused sound wave emitting device 112. Using its special geometric shape, it reflects and refracts the planar ultrasonic waves emitted by the focused sound wave emitting device 112, thereby focusing the planar ultrasonic waves into focused ultrasonic waves.

[0041] Illustratively, during the ultrasonic wave generation phase, the acoustic wave emitting assembly 110 of the ultrasonic transducer 100 is connected to a circuit. The planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 of the acoustic wave emitting assembly 110, under the control of their respective drive circuits, convert electrical signals into ultrasonic signals. For example, assuming the ultrasonic transducer 100 is a piezoelectric ultrasonic transducer, the piezoelectric material (e.g., piezoelectric ceramic) within the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 generates mechanical vibrations due to the inverse piezoelectric effect under the action of the electrical signal. This vibration propagates through the medium, forming a planar ultrasonic wave. During the ultrasonic wave focusing phase, the planar ultrasonic wave emitted by the focused acoustic wave emitting device 112 propagates into space. When it encounters the concave structure 121 within the acoustic wave adjustment assembly 120 of the device, the special curved surface of the concave structure 121 causes the planar ultrasonic wave to be reflected and refracted on its surface. These reflected and refracted ultrasonic waves propagate through space and overlap at a specific location. By precisely designing the geometric parameters of concave structure 121, these superimposed ultrasonic waves can be made to interfere and intensify at a predetermined location, thereby focusing the originally dispersed planar ultrasonic waves into highly concentrated focused ultrasonic waves. For example, when concave structure 121 is parabolic, parallel incident planar ultrasonic waves, after being reflected by the parabola, converge at the parabola's focal point, forming a focused ultrasonic wave.

[0042] Taking the ultrasonic transducer 100 as a piezoelectric ultrasonic transducer as an example, it can be understood that the piezoelectric material in the ultrasonic transducer 100 can be a piezoelectric ceramic, the concave structure 121 can be a multi-morphous energy-gathering material, and a sound-transmitting material can also be provided in the plane acoustic wave emitting device 111 to adjust the plane ultrasonic wave emitted by the plane acoustic wave emitting device 111. The sound-transmitting material does not refract ultrasonic waves, and the multi-morphous energy-gathering material refracts ultrasonic waves. A conventional acoustic lens is generally used, and it can also be a liquid sound velocity gradient lens, a solid sound velocity lens, a flexible wearable lens, etc.

[0043] Furthermore, in the present application, the intensity of the focused ultrasound can be adjusted by adjusting the number of the concave structures 121, such as Figure 2 As shown, the surface of the multi-morphological energy-gathering material of the focused acoustic wave emitting device 112 can be distributed with a number of small concave structures, that is, a concave structure within a concave structure. The intensity of the focused ultrasonic wave can be adjusted by controlling the number and angle of the concave structures 121.

[0044] The above-mentioned ultrasonic transducer includes an acoustic wave emitting component, and a planar acoustic wave emitting device and a focused acoustic wave emitting device are integrated in the acoustic wave emitting component. The planar acoustic wave emitting device emits planar ultrasonic waves, and the focused acoustic wave emitting device emits planar ultrasonic waves. However, since the focused acoustic wave emitting device includes at least one concave structure, the concave structure can focus the planar ultrasonic waves. This structural sound field control method has a fast response speed and strong focusing stability. Therefore, the focused acoustic wave emitting device can output stable focused ultrasonic waves. The planar acoustic wave emitting device is used to emit planar ultrasonic waves. In this way, the planar ultrasonic function and the focused ultrasonic function can be integrated into one ultrasonic transducer. In multi-ultrasound mode application scenarios, the above-mentioned ultrasonic transducer can be used to achieve two types of ultrasonic output without frequently replacing probes or switching equipment, thereby improving the continuity of use and ease of operation of the ultrasonic transducer.

[0045] In one embodiment, Figure 3 As shown, the acoustic wave emitting component 110 includes a multi-channel driving circuit 113, which is respectively connected to the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112. The multi-channel driving circuit 113 is configured to support simultaneous driving, time-sharing driving, or alternating driving of the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 to emit ultrasonic waves.

[0046] Among them, the multi-channel driving circuit 113 can output multiple electrical signals, thereby providing driving signals that meet the requirements of different operating modes for the plane acoustic wave emitting device 111 and the focused acoustic wave emitting device 112. Simultaneous driving is an operating mode of the multi-channel driving circuit 113, which means that the multi-channel driving circuit 113 outputs driving signals to the plane acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 at the same time, so that the two acoustic wave emitting devices start emitting ultrasonic waves at the same time. Time-sharing driving is an operating mode in which the multi-channel driving circuit 113 outputs driving signals to the plane acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 in sequence according to a pre-set time sequence. Within one working cycle, the two acoustic wave emitting devices alternately emit ultrasonic waves. In the alternating driving mode, the multi-channel driving circuit 113 periodically switches the output of the driving signal between the plane acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 at a fixed period or specific trigger conditions. Unlike the time-sharing driving mode, the alternating driving mode focuses on the periodicity and regularity of the sound waves emitted from the two areas.

[0047] For example, in the acoustic wave emitting assembly 110 of the ultrasonic transducer 100, the multi-channel driving circuit 113 is connected to the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 through electrical connection lines, so that the driving signal can be stably and efficiently transmitted to the two emitting areas. When the ultrasonic transducer 100 is in working state, the multi-channel driving circuit 113 drives the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 according to the preset working mode or the control instruction input from the external. In the simultaneous driving mode, the signal processing module of the multi-channel driving circuit 113 drives the piezoelectric material in the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 to vibrate. At this time, the piezoelectric material in the two areas is simultaneously acted upon by the driving signal, and the electrical energy is converted into ultrasonic energy and emitted, that is, the planar ultrasonic wave and the focused ultrasonic wave are output simultaneously. In the time-sharing drive mode, the multi-channel drive circuit 113 outputs drive signals to the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 in a time-sharing manner according to a preset time sequence. For example, in a complete working cycle, the drive signal in the first half of the cycle is transmitted to the planar acoustic wave emitting device 111, causing it to emit planar ultrasonic waves, and the drive signal in the second half of the cycle is switched to the focused acoustic wave emitting device 112, driving the acoustic wave emitting device to emit focused ultrasonic waves. In the alternating drive mode, the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 receive the drive signals alternately, so that the two acoustic wave emitting devices alternately emit ultrasonic waves according to a fixed cycle.

[0048] It can be understood that the driving circuits 113 of the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 do not interfere with each other. In addition to simultaneous driving, time-sharing driving, and alternating driving, different acoustic wave emitting devices can also be controlled separately to emit ultrasonic waves. It is only necessary to control the driving circuit 113 corresponding to the acoustic wave emitting device to emit a driving signal. For example, the planar acoustic wave emitting device 111 emits planar ultrasonic waves, while the focused acoustic wave emitting device 112 does not emit sound waves.

[0049] In this embodiment, the multi-channel driving circuit supports at least three working modes: simultaneous driving, time-sharing driving or alternating driving, and the independence of the driving circuit makes the planar ultrasonic transmission function and focused ultrasonic transmission function integrated in the ultrasonic transducer relatively independent. Different driving modes correspond to different ultrasonic types, which can improve the convenience of using the ultrasonic transducer.

[0050] In one embodiment, Figure 4 As shown, the emission area of ​​the planar acoustic wave emission device 111 and the emission area of ​​the focused acoustic wave emission device 112 are in an inclusive relationship or a cross-arranged relationship.

[0051] In the acoustic wave emitting assembly 110, the emission area of ​​the planar acoustic wave emitting device 111 and the emission area of ​​the focused acoustic wave emitting device 112 can be nested, specifically in two forms: first, the emission area of ​​the planar acoustic wave emitting device 111 serves as the peripheral area, and the emission area of ​​the focused acoustic wave emitting device 112 serves as the inner sub-area, completely surrounded by it; second, the emission area of ​​the focused acoustic wave emitting device 112 serves as the peripheral area, and the emission area of ​​the planar acoustic wave emitting device 111 serves as the inner sub-area, completely surrounded by it. This nested design can achieve layered emission of ultrasound. Through the coordinated operation of planar ultrasound or focused ultrasound in the inner and outer layers, better ultrasound application effects can be achieved. The emission areas of the planar acoustic wave emitting device 111 and the emission areas of the focused acoustic wave emitting device 112 can also be arranged in an alternating spatial distribution. Specific implementation forms include: checkerboard arrangement (the two areas are alternately distributed in square units), stripe arrangement (the two areas are alternately arranged in parallel strips), honeycomb arrangement, etc.

[0052] For example, when a structure is adopted in which the emission area of ​​the planar acoustic wave emitting device 111 includes the emission area of ​​the focused acoustic wave emitting device 112, the multi-channel driving circuit 113 can independently control the working status of the inner and outer layer areas. For example, in an ultrasonic beauty scene, the outer plane acoustic wave emitting device 111 can emit planar ultrasonic waves, and the inner focused acoustic wave emitting device 112 can emit focused ultrasonic waves. Through this double-layer structural design, while achieving efficient treatment, the risk of damage to surrounding healthy tissues can be reduced. When the emission area of ​​the focused acoustic wave emitting device 112 includes the emission area of ​​the planar acoustic wave emitting device 111, the inner plane acoustic wave emitting device 111 can emit planar ultrasonic waves, and the outer focused acoustic wave emitting device 112 can emit focused ultrasonic waves.

[0053] In addition, when the emission area of ​​the planar acoustic wave emitting device 111 and the emission area of ​​the focused acoustic wave emitting device 112 are arranged crosswise, refer to the attached Figure 3 As shown, the emission area of ​​the plane acoustic wave emitting device 111 can be set between the emission areas of the focused acoustic wave emitting device 112, with the plane ultrasonic wave emitted in the middle and the focused ultrasonic wave emitted on both sides. Similarly, the emission area of ​​the focused acoustic wave emitting device 112 can be set between the emission areas of the plane acoustic wave emitting device 111, with the focused ultrasonic wave emitted in the middle and the plane ultrasonic wave emitted on both sides. It is understandable that the distribution of the emission areas of the plane acoustic wave emitting device 111 and the emission areas of the focused acoustic wave emitting device 112 can be flexibly designed according to the actual usage scenario and space limitations, thereby improving the operability and feasibility of the ultrasonic transducer 100.

[0054] In this embodiment, by changing the distribution relationship between the emission area of ​​the planar acoustic wave emitting device and the emission area of ​​the focused acoustic wave emitting device, the frequency stratification and energy gradient distribution of ultrasound can be achieved, so that the ultrasonic waves emitted by the ultrasonic transducer can better meet actual needs. In addition, the integration of planar ultrasonic emission and focused ultrasonic emission does not require the mechanical combination of multiple independent transducers, which can effectively reduce the overall size of the ultrasonic transducer and significantly improve the portability and ease of use of the ultrasonic transducer.

[0055] In one embodiment, the emission area of ​​the planar acoustic wave emitting device 111 and the emission area of ​​the focused acoustic wave emitting device 112 are both divided into multiple sub-areas, and the number of sub-areas emitting ultrasonic waves is positively correlated with the intensity of the ultrasonic waves emitted by the planar acoustic wave emitting device 111 or the focused acoustic wave emitting device 112.

[0056] Among them, in order to achieve refined control of ultrasonic emission, the emission area of ​​the planar acoustic wave emitting device 111 and the emission area of ​​the focused acoustic wave emitting device 112 can be further divided into multiple smaller functional units, namely sub-areas. Each sub-area can independently perform electrical-to-acoustic conversion and emit ultrasonic waves with specific parameters under the control of the multi-channel driving circuit 113. In the actual working process, the number of sub-areas activated and emitting ultrasonic waves by the multi-channel driving circuit 113 is not fixed, but can be dynamically adjusted according to system requirements and control instructions. By changing the number of sub-areas participating in the emission, the overall emission intensity of the ultrasonic waves of the planar acoustic wave emitting device 111 or the focused acoustic wave emitting device 112 can be regulated.

[0057] Specifically, in the acoustic wave emitting assembly 110 of the ultrasonic transducer 100, the emission area of ​​the planar acoustic wave emitting device 111 and the emission area of ​​the focused acoustic wave emitting device 112 are each finely divided into a plurality of sub-areas. These sub-areas are physically independent of each other and can convert electrical energy into acoustic energy under the excitation of an electrical signal and independently emit ultrasonic waves, thereby achieving directional and individual control of the sub-areas. For example, when it is necessary to adjust the intensity of the ultrasonic waves emitted by the planar acoustic wave emitting device 111 or the focused acoustic wave emitting device 112, the multi-channel driving circuit 113 can determine which sub-areas to activate according to a preset program or an external input control instruction. If it is desired to increase the intensity of the emitted ultrasonic waves, the number of sub-areas emitting ultrasonic waves into the planar acoustic wave emitting device 111 or the focused acoustic wave emitting device 112 can be increased. Because each sub-area emits ultrasonic waves of a certain energy, more sub-areas working simultaneously means that more energy is converted and emitted, thereby enhancing the overall emitted ultrasonic wave intensity. Conversely, if it is necessary to reduce the ultrasonic wave intensity, the number of sub-areas emitting ultrasonic waves can be reduced, reducing the energy output and achieving a reduction in ultrasonic wave intensity.

[0058] For example, the piezoelectric ceramics of the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 can be divided into multiple subunits, each corresponding to a subregion. Different subunits can be driven independently, thereby enabling the superposition of acoustic wave regions and acoustic wave energy. The division methods include, but are not limited to, strip division, circular division, diamond division, honeycomb division, and the like.

[0059] In this embodiment, by dividing the emission area of ​​the planar acoustic wave emitting device and the emission area of ​​the focused acoustic wave emitting device into multiple sub-areas, and controlling the ultrasonic intensity according to the number of sub-areas emitting ultrasonic waves, precise control of the ultrasonic intensity emitted by the planar acoustic wave emitting device or the focused acoustic wave emitting device can be achieved, thereby making the ultrasonic wave more flexible and controllable, and being able to meet the diverse requirements of different application scenarios for ultrasonic intensity, direction, waveform, etc.

[0060] In one embodiment, Figure 5 As shown, the ultrasonic transducer 100 further includes a housing 130 , and the sound wave emitting assembly 110 is embedded in the housing 130 .

[0061] The housing 130 is an external structural component of the ultrasonic transducer 100, used to protect internal components and provide mechanical support. It can be made of metal, engineering plastic, or a composite material. In this embodiment, the acoustic wave transmitting assembly 110 is surrounded by the housing 130, which provides a physical boundary and protective barrier for the acoustic wave transmitting assembly 110. However, the ultrasonic waves emitted by the acoustic wave transmitting assembly 110 can be transmitted smoothly from the housing 130.

[0062] For example, the housing 130 has a reserved space and structure for mounting the acoustic wave emitting assembly 110. During assembly, the acoustic wave emitting assembly 110 is precisely placed in a pre-set position within the housing 130 and secured to the housing 130 via mechanical connections (such as screws, snap-fit ​​connections, etc.) or adhesives. For example, the housing 130 employs an embedded, encapsulated design, with the piezoelectric ceramics of the acoustic wave emitting assembly 110 embedded within the housing 130, encapsulated externally, and then bonded to a polymorphic energy-gathering material to form the acoustic wave adjustment assembly 120. The housing 130 can be designed in various shapes, including but not limited to circular, square, and ellipsoidal, depending on the focal area and focus region. For example, if the housing 130 is cylindrical, multiple cable outlets are reserved and sealed with epoxy resin for waterproofing. Once embedded within the housing 130, the housing 130 provides physical protection for the acoustic wave emitting assembly 110, protecting it from external factors such as mechanical impact, dust, and moisture. The ultrasonic wave emitted by the acoustic wave emitting assembly 110 is emitted from the front end surface of the housing 130 (ie, the surface in the ultrasonic wave emitting direction) and enters the medium or the active area.

[0063] In this embodiment, the housing can protect the internal structure and electronic components of the acoustic wave emitting assembly from damage, thereby stabilizing the performance of the ultrasonic transducer and improving the reliability and efficiency of the ultrasonic transducer.

[0064] In one embodiment, Figure 6 As shown, an isolation component 140 is provided between the emission area of ​​the plane acoustic wave emitting device 111 and the emission area of ​​the focused acoustic wave emitting device 112. The isolation component 140 is used to isolate the planar ultrasonic waves emitted by the plane acoustic wave emitting device 111 and the focused ultrasonic waves emitted by the focused acoustic wave emitting device 112.

[0065] The isolation assembly 140 is disposed between the emission area of ​​the planar acoustic wave emitting device 111 and the emission area of ​​the focused acoustic wave emitting device 112 of the ultrasonic transducer 100 to reduce or prevent mutual interference between the ultrasonic waves emitted from the two areas. It will be appreciated that the isolation assembly 140 is typically made of a material with specific acoustic properties, such as a sound-absorbing material, a sound-insulating material, or a composite material of the two. Through physical structural design and material properties, it achieves isolation of ultrasonic waves with different characteristics.

[0066] For example, the distribution of the emission area of ​​the planar acoustic wave emitting device 111 and the emission area of ​​the focused acoustic wave emitting device 112 is taken as an example of inside and outside inclusion. Figure 6 As shown, the isolation assembly 140 can be disposed at the junction of the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112. In the acoustic wave emitting assembly 110 of the ultrasonic transducer 100, the planar acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 each perform different ultrasonic wave emitting tasks: the former emits planar ultrasonic waves, while the latter, under the influence of the concave structure 121, emits focused ultrasonic waves. Because the two regions are spatially adjacent, if effective isolation is not performed, the ultrasonic waves emitted by them may interfere with each other during propagation, thereby potentially affecting the overall performance of the ultrasonic transducer 100. The isolation component 140 is precisely arranged between the emission area of ​​the plane acoustic wave emitting device 111 and the emission area of ​​the focused acoustic wave emitting device 112. Based on the sound absorption and sound insulation properties of the acoustic material, it reduces the propagation of the planar ultrasonic wave emitted by the plane acoustic wave emitting device 111 toward the focused acoustic wave emitting device 112. Similarly, it reduces the propagation of the focused ultrasonic wave emitted by the focused acoustic wave emitting device 112 toward the plane acoustic wave emitting device 111. Through this two-way isolation effect, the plane acoustic wave emitting device 111 and the focused acoustic wave emitting device 112 can work relatively independently and each perform its designed function.

[0067] In this embodiment, the isolation component effectively reduces the ultrasonic interference between the planar acoustic wave emitting device and the focused acoustic wave emitting device, so that the ultrasonic waves emitted from the two areas can maintain stable waveform, frequency, intensity and other characteristics, meet the needs of high-precision detection or treatment, and improve the use accuracy of the ultrasonic transducer.

[0068] In one embodiment, an ultrasonic control method is provided, such as Figure 7 As shown, the method applied to the ultrasonic transducer 100 in any of the above embodiments includes the following steps:

[0069] S100, obtaining the user's skin condition data or the working mode parameters selected by the user.

[0070] Among them, skin condition data includes but is not limited to skin moisture content, oil secretion, skin elasticity, stratum corneum thickness, presence of spots, wrinkles and other data. These data can be measured and analyzed by skin moisture testers, spectrometers, image acquisition equipment, etc., and used to evaluate the current state of the user's skin. For example, the user's skin condition data can be obtained in a variety of ways. For example, the skin detection module of the ultrasonic transducer, such as the built-in micro-spectral sensor, can be used to perform spectral analysis on the skin to obtain information such as skin pigment distribution and water content, or through an image acquisition camera combined with an image recognition algorithm to analyze the skin's texture, blemishes and other conditions. The working mode parameters selected by the user are the personalized demand information related to the use of the ultrasonic transducer expressed subjectively by the user, such as the user's desired ultrasonic intensity preference, ultrasonic emission duration preference, action site preference, and action mode preference.

[0071] For example, the working mode parameters selected by the user can be obtained in a variety of ways. Options can be set in the operating interface of the ultrasonic transducer to guide the user to manually select the desired treatment intensity, time and other parameters. The user's past history of using the ultrasonic transducer can also be used to mine the working mode parameters selected by the user using a data analysis algorithm. In actual applications, either skin condition data or user-selected working mode parameters can be obtained separately, or both data can be obtained at the same time to more comprehensively understand user needs. In addition, when obtaining skin condition data and user-selected working mode parameters at the same time, the user-selected working mode parameters can be given priority to better meet the user's needs.

[0072] S200 , determining the operating mode of the ultrasonic transducer according to skin condition data or operating mode parameters selected by the user.

[0073] Different operating modes correspond to different combinations of operating parameters of the ultrasonic transducer, including but not limited to the ultrasonic transmission frequency, transmission intensity, transmission waveform, transmission duration, and interval time. Similarly, different operating mode parameters selected by the user will result in different parameters such as the type, duration, and intensity of ultrasonic transmission from the ultrasonic transducer.

[0074] Continuing with the above steps, if skin condition data is obtained, the working mode can be determined according to the user's different skin conditions. For example, if the user's skin is detected to be dry and dehydrated, you can choose to first use planar ultrasound treatment to promote water absorption and metabolism deep in the skin, and then use focused ultrasound treatment.

[0075] If the operating mode parameters selected by the user are obtained, for example, through input on a user operation interface, analysis of historical usage records, or other interactive methods, the operating mode selected by the user will be matched to an appropriate operating mode for the user based on the operating mode parameters selected by the user. The operating modes of the ultrasonic transducer include simultaneously controlling and sequentially controlling the planar acoustic wave emitting device and the focused acoustic wave emitting device to emit ultrasonic waves. If the user selects "first use planar ultrasonic waves, then use focused ultrasonic waves" on the operation interface, the multi-channel drive circuit of the ultrasonic transducer will drive the acoustic wave emitting component to emit the corresponding ultrasonic waves based on the operating mode selected by the user.

[0076] S300: Detect whether the sound wave emitting component of the ultrasonic transducer is in contact with the user's skin.

[0077] Specifically, contact detection sensors, such as pressure sensors and capacitive sensors, can be provided on the acoustic wave emitting component of the ultrasonic transducer or around the outer shell. The pressure sensor can sense the pressure changes generated when the acoustic wave emitting component contacts the skin. When the pressure reaches a preset threshold, it is determined that the acoustic wave emitting component is in contact with the user's skin. The capacitive sensor determines whether there is contact by detecting changes in the capacitance between the acoustic wave emitting component and the skin. In addition, infrared sensing and other methods can be used to detect the distance between the skin and the transducer. When the distance is less than a certain value, it is determined that the acoustic wave emitting component is in contact with the user's skin.

[0078] S400, when it is detected that the sound wave emitting component of the ultrasonic transducer is in contact with the user's skin, controlling the ultrasonic transducer to emit ultrasonic waves in a working mode

[0079] Following the above steps, upon detecting contact between the acoustic wave emitting assembly and the skin, the ultrasonic transducer's multi-channel drive circuit adjusts to a parameter state that matches the operating mode. Based on the set parameters, the multi-channel drive circuit outputs corresponding electrical signals to the planar acoustic wave emitting device and the focused acoustic wave emitting device, driving the piezoelectric material to vibrate, thereby emitting ultrasonic waves that meet the operating mode requirements. It will be appreciated that during the ultrasonic emission process, the ultrasonic emission status and skin contact can also be monitored in real time. If contact is interrupted or an abnormality occurs, the ultrasonic emission status will be immediately paused or adjusted.

[0080] The above-mentioned ultrasonic control method, device, computer equipment, readable storage medium and computer program product obtain the user's skin condition data or the working mode parameters selected by the user. The skin conditions of different users will directly affect the working mode of the ultrasonic transducer. The working mode parameters selected by the user reflect the user's preferences. Different from the preset working mode in the traditional scheme, this application uses the user's skin condition data or the working mode parameters selected by the user. The working mode of the ultrasonic transducer includes simultaneous control and sequential control of the planar sound wave emitting device and the focused sound wave emitting device to emit ultrasonic waves. In this way, the working mode of the ultrasonic transducer is personalized to improve the targeted nature of the ultrasonic operation. When the sound wave emitting component of the ultrasonic transducer contacts the user's skin, the working mode is started, which can reduce misoperation or empty emission and enhance the operational convenience of ultrasonic control.

[0081] In one embodiment, Figure 8 As shown, S200 includes any of the following:

[0082] S210 , upon receiving the operating mode parameters selected by the user, determining the operating mode of the ultrasonic transducer according to the operating mode parameters selected by the user.

[0083] S220, when the working mode parameters selected by the user are not received, the user's skin type is determined based on the skin condition data, and the skin types include oily skin, dry skin and sensitive skin. When the user's skin type is oily skin or sensitive skin, the working mode of the ultrasonic transducer is determined to be the first working mode. When the user's skin type is dry skin, the working mode of the ultrasonic transducer is determined to be the second working mode or the third working mode.

[0084] Among them, in the first working mode, the planar sound wave emitting device of the ultrasonic transducer first emits planar ultrasonic waves, and the focused sound wave emitting device then emits focused ultrasonic waves; in the second working mode, the focused sound wave emitting device of the ultrasonic transducer first emits focused ultrasonic waves, and the planar sound wave emitting device then emits planar ultrasonic waves; in the third working mode, the planar sound wave emitting device of the ultrasonic transducer emits planar ultrasonic waves, and the focused sound wave emitting device emits focused ultrasonic waves at the same time.

[0085] When the operating mode parameters selected by the user are received, the operating mode is determined directly based on the operating mode parameters selected by the user, which can meet the user's personalized usage needs to the greatest extent. Specifically, after obtaining the operating mode parameters selected by the user through user operation interface input, historical usage record analysis or other interactive methods, the appropriate operating mode will be matched to the user based on the operating mode parameters selected by the user. For example, if the user selects "first use planar ultrasound, then use focused ultrasound" in the operation interface, the multi-channel driving circuit of the ultrasonic transducer will drive the sound wave transmitting component to emit the corresponding ultrasonic wave according to the operating mode selected by the user.

[0086] Even if the user-selected operating mode parameters are not received, the system can still obtain the user's skin condition data and, based on the skin's physiological characteristics and performance features, categorize the user's skin into different skin types, including oily, dry, and sensitive. Oily skin is typically characterized by high oil secretion, while dry skin is characterized by low moisture and oil secretion, resulting in dryness and roughness. Sensitive skin is characterized by a weak skin barrier function and increased sensitivity to external stimuli (such as temperature fluctuations and cosmetics). Different skin types have different adaptability to and requirements for ultrasound treatment, so the operating mode that best suits the user's skin type can be customized.

[0087] For example, the user's skin type can be judged through a comprehensive assessment of skin condition data. If the skin's oil secretion is detected to be higher than the normal threshold, the moisture content is within the normal range, and the pores are relatively large, it is determined to be oily skin. If the skin's moisture content is far below the normal standard, the oil secretion is low, the skin texture is rough, and there is obvious desquamation, it is determined to be dry skin. If the skin is sensitive to slight stimulation and the indicators related to the skin barrier function are abnormal, it is determined to be sensitive skin. After determining the skin type, the working mode of the ultrasonic transducer will be determined according to the user's skin type. For example, for oily skin, the ultrasonic transducer's planar acoustic wave emitting device will first emit planar ultrasonic waves. The low-energy treatment will have a buffering and adaptive effect, and can also dredge oil, making the ultrasonic wave effect on the skin more efficient. The focused ultrasonic wave emitting device will then emit focused ultrasonic waves.

[0088] Furthermore, in the first working mode, the planar sound wave emitting device of the ultrasonic transducer first emits planar ultrasonic waves, and the focused sound wave emitting device then emits focused ultrasonic waves. When the user has dry skin, the working mode of the ultrasonic transducer is the second working mode or the third working mode. In the second working mode, the focused sound wave emitting device of the ultrasonic transducer first emits focused ultrasonic waves, and the planar sound wave emitting device then emits planar ultrasonic waves. In the third working mode, the planar sound wave emitting device of the ultrasonic transducer emits planar ultrasonic waves, and the focused sound wave emitting device simultaneously emits focused ultrasonic waves.

[0089] Specifically, the first operating mode is a specially designed ultrasonic transducer operating mode for users with oily and sensitive skin. In this mode, by controlling the ultrasonic transmission timing of the planar and focused acoustic wave emitting devices, the planar acoustic wave emitting device first emits planar ultrasonic waves, followed by the focused ultrasonic wave emitting device. This primarily opens skin channels with planar ultrasound, and then tightens the skin with focused ultrasound, significantly improving the transmission efficiency of ultrasound therapy and enhancing its therapeutic effect. For example, a planar acoustic wave emitting device may first emit low-frequency planar ultrasonic waves with a frequency of 20-60 kHz. Through stamp-like mobile covering treatment, the user's facial skin can be divided into multiple areas from bottom to top. Planar ultrasonic waves are first applied to the lowest area for a period of time, for example, 5-10 minutes. An infrared thermometer is used to detect whether the skin surface temperature reaches 37-42°C. A skin impedance analyzer can also be used to check its permeability. After reaching this time and temperature, the focused acoustic wave emitting device is controlled to emit focused ultrasonic waves. 10-12 focused ultrasonic waves are emitted to the area. During this process, the user's pain sensation can be observed and the energy of the focused ultrasonic waves can be adjusted in time. Then, similar treatment is performed on each area of ​​the facial skin.

[0090] The second operating mode is designed for users with dry skin. In this mode, the ultrasonic transducer's focused ultrasonic wave emitting device 112 first emits focused ultrasonic waves, followed by the planar ultrasonic wave emitting device. By adjusting the order of these two ultrasonic wave emission, the system can meet the specific needs of dry skin and improve dry skin conditions. For example, focused ultrasonic waves are first emitted to the user's facial skin, followed by planar ultrasonic waves in combination with a repair serum. This allows damaged cells in the fascia layer to regenerate faster and allows the repair serum's whitening and anti-wrinkle factors to quickly penetrate the skin. Specifically, 100-140 focused ultrasonic waves are first emitted to the user's skin, followed by planar ultrasonic waves. This is combined with a mask or gel (the rapid repair serum is poured over the mask or gel) for 10-30 minutes, with the temperature controlled below 40°C throughout the entire process.

[0091] The third operating mode is also suitable for users with dry skin. In this mode, the planar and focused ultrasonic wave emitting devices simultaneously emit planar and focused ultrasonic waves. Leveraging the combined effect of the two ultrasonic waves, this system enhances the care or treatment of dry skin and promotes the skin's absorption of moisture and nutrients. The dual effects of planar and focused ultrasonic waves in this third mode result in more immediate benefits for the user's skin. Specifically, by emitting both planar and focused ultrasonic waves simultaneously, if the user's facial skin is divided into six zones, each zone can emit 10-14 ultrasonic waves, resulting in a total duration of 40-60 minutes.

[0092] In this embodiment, a specific working mode is set according to the user's different skin types or the working mode parameters selected by the user, so that the ultrasonic transducer can accurately meet the needs of users with different skin types and different preferences. For oily skin, the ultrasonic emission sequence and characteristics of the first working mode can effectively cleanse the skin and regulate oil secretion. Sensitive skin can achieve skin repair under the premise of safety in the first working mode. Dry skin can improve skin dryness from different angles through the second and third working modes, improve the skin's moisturizing and nutrient absorption capacity, and significantly improve the pertinence and effectiveness of the ultrasonic transducer in skin care.

[0093] In one embodiment, the emission area of ​​the planar acoustic wave emission device and the emission area of ​​the focused acoustic wave emission device are both divided into multiple sub-areas. After S200, the method further includes:

[0094] Receive a working gear selected by a user, determine the intensity of the ultrasonic wave emitted by the ultrasonic transducer according to the working gear selected by the user, and determine the number of sub-areas emitting ultrasonic waves in the planar acoustic wave emitting device and the focused acoustic wave emitting device of the ultrasonic transducer based on the intensity of the ultrasonic wave, wherein the number of sub-areas emitting ultrasonic waves is positively correlated with the intensity of the ultrasonic wave emitted by the planar acoustic wave emitting device or the focused acoustic wave emitting device.

[0095] The operating level is the user-selectable level of ultrasonic transducer intensity, presented numerically or in text (e.g., 1-5 or weak, medium, strong). Each level corresponds to a specific range of ultrasonic emission intensity, which users can select based on their skin tolerance and needs. Ultrasonic intensity is the power of ultrasound per unit area. Ultrasonic waves of varying intensities affect skin tissue to varying depths and degrees. The number of subregions refers to the number of independent control units in a planar or focused acoustic wave transmitter that actually transmit ultrasound. A greater number of subregions means more piezoelectric material is operating simultaneously, resulting in a higher intensity of transmitted ultrasound waves. The two are positively correlated.

[0096] Specifically, the user inputs the desired working gear through the operating interface of the ultrasonic transducer (such as a touch screen, buttons, etc.). For example, if the user selects "Gear 3", the ultrasonic transducer will convert it into a corresponding ultrasonic intensity value according to a preset gear-intensity mapping table, and further calculate the number of sub-areas that need to be activated in the planar acoustic wave emitting device and the focused acoustic wave emitting device based on the determined ultrasonic intensity value. The ultrasonic intensity value emitted by each sub-area can be fixed. The more sub-areas that emit ultrasonic waves, the higher the superimposed ultrasonic intensity, that is, the number of sub-areas is positively correlated with the emission intensity. In addition, the number of sub-areas that need to be activated in the acoustic wave emitting device can be dynamically adjusted according to the user's skin condition data (such as skin type, skin sensitivity, user skin tolerance, etc.) to avoid damage to the skin.

[0097] In this embodiment, fine-tuning of the ultrasonic intensity is achieved through the associated control of the working gear and the number of sub-areas. Users can select the appropriate gear according to their own needs, and then dynamically adjust the number of working sub-areas according to the working gear selected by the user, reducing unnecessary energy consumption. Compared with the traditional fixed-intensity emission mode, this solution can significantly reduce energy consumption and achieve fine-tuning of the ultrasonic intensity while meeting user needs.

[0098] In one embodiment, when the working mode is the first working mode, after the planar acoustic wave emitting device of the ultrasonic transducer emits planar ultrasonic waves, the method also includes: obtaining the user's skin temperature and skin impedance, and only when the acoustic wave emission duration of the planar acoustic wave emitting device is greater than a preset duration threshold, the skin temperature is within a preset skin temperature range, and the skin impedance is less than a preset impedance threshold, the focused acoustic wave emitting device of the ultrasonic transducer emits focused ultrasonic waves.

[0099] Among them, the user's skin temperature can be monitored in real time through infrared temperature sensors or contact temperature sensors. The normal skin temperature range is generally between 32°C and 35°C. When ultrasound acts on the user's skin, temperatures that are too high may cause skin burns, while temperatures that are too low may indicate that the ultrasound energy is not effectively acting on the skin tissue. Skin impedance is determined by factors such as the water content and ion concentration of the skin's stratum corneum. The user's skin impedance can be calculated by setting electrodes on the surface of the ultrasound transducer, applying a small current, and measuring the voltage change. The change in skin impedance can reflect the hydration state and permeability of the skin's stratum corneum and can be used to evaluate the effect of ultrasound on skin penetration.

[0100] For example, the ultrasonic transducer can collect the skin temperature and skin impedance of the user's skin in real time through an integrated temperature sensor and impedance detection electrode. Then, it checks whether the acoustic wave emission duration of the planar acoustic wave emitting device exceeds a preset duration threshold. If the duration threshold is not reached, the planar ultrasonic wave continues to be emitted. If the duration threshold is reached or exceeded, it is further determined whether the skin temperature is within a preset skin temperature range and whether the skin impedance is less than a preset impedance threshold. Only when the above three conditions are met at the same time will the focused acoustic wave emitting device be triggered to emit focused ultrasonic waves. At this time, it can be considered that the user's skin channel has been opened and the skin can be tightened by focused ultrasonic waves.

[0101] In this embodiment, real-time skin temperature monitoring ensures that the skin temperature remains within a safe range during ultrasound treatment, effectively reducing adverse reactions such as skin burns caused by excessive temperatures and enhancing the safety of the ultrasound transducer. Real-time skin impedance monitoring ensures that the skin reaches optimal permeability before focused ultrasound is emitted. This allows the focused ultrasound to more effectively penetrate the skin and reach deeper tissues, improving the delivery efficiency of drugs or nutrients and thus enhancing the effectiveness of the ultrasound.
