However, the existing clip-on earphones generally have a problem, that is, the clamping force is usually fixed or can only be manually adjusted within a limited range, and it is difficult for users to accurately judge whether it is suitable for their ear comfort needs when purchasing.

[0003] Moreover, the ear shapes, sizes and tolerance of clamping pressure of different users are different. If the clamping force is too large, long-term wearing will cause ear pain and discomfort, and even may affect the blood circulation and hearing health of the ear; and if the clamping force is too small, the earphone may not be worn stably, which affects the use effect, especially in the activity scene. CONTENT OF THE UTILITY MODEL

[0011] Further, the host further comprises a power module, which is connected to the pressure sensor, the driving assembly and the signal processing module through current transmission lines respectively.

[0025] To make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] This embodiment provides a clip-on earphone, such as Figures 1-4 As shown, it includes: a host 1, a drive component 3, and a clamping component 2. The drive component 3 is installed inside the host 1, and its power end is connected to the clamping component 2. The clamping component 2 is rotatably disposed at one end of the host 1 and forms an adjustable clamping position 4 between itself and the host 1. A pressure sensor that can contact the human ear is provided in the clamping position 4. The pressure sensor is electrically connected to the drive component 3.

[0029] This ear-clamping headphone design aims to solve the problem of fixed clamping force or limited adjustment range in existing products. By introducing advanced pressure sensing and automatic adjustment technology, it provides a personalized wearing experience for users with different ear characteristics. The main structure of the headphone includes a main unit 1, a driver component 3, and a clamping component 2. The driver component 3 is installed inside the main unit 1, and its power end is directly connected to the clamping component 2. The clamping component 2 is rotatably mounted on one end of the main unit 1, forming a clamping position 4 that can be flexibly adjusted in size. Crucially, the clamping position 4 has a built-in precision pressure sensor. This sensor is in close contact with the user's ear and can monitor and provide feedback on the pressure value generated during clamping in real time.

[0030] When the user wears the earphone, the pressure sensor is immediately started, accurately captures the pressure on the ear, and converts this physical quantity into an electrical signal, which is then transmitted to the host 1 through the circuit. After receiving the signal, it is quickly analyzed, and according to the user's pre-set comfortable clamping force range, the current clamping state is intelligently judged. Once it is detected that the clamping force exceeds or is lower than the set range, an adjustment instruction is sent to the driving assembly 3, and the driving assembly 3 responds to the instruction and dynamically adjusts its output force, thereby realizing fine control of the clamping force of the clamping assembly 2. This process is continuous and real-time, ensuring that the earphone can be clamped on the ear at the most suitable force at any time.

[0031] The significant advantage of this design is that it significantly improves the wearing comfort of the earphone, effectively avoiding ear pain, blood circulation obstruction and hearing health risks caused by improper clamping force. At the same time, users can freely set the ideal range of clamping force according to personal preferences and ear characteristics, realizing a highly personalized wearing experience. In addition, the automatic adjustment mechanism also ensures stable wearing of the earphone in various activity scenarios, whether it is daily travel, office work, or intense exercise, it can maintain the best wearing state. In summary, this clamping earphone with its innovative technology application and humanized design concept brings users a more excellent wearing experience and health protection.

[0032] Further, the position of the host 1 in contact with the concha cavity is the first clamping part 101, and the position of the clamping assembly 2 in contact with the back of the ear is the second clamping part 203; the pressure sensor is arranged at the first clamping part 101; and / or the pressure sensor is arranged at the second clamping part 203. In these two key clamping parts, the configuration of the pressure sensor is particularly important, as it directly affects the monitoring accuracy and control effect of the earphone on the clamping pressure. Specifically, the pressure sensor can be arranged at the first clamping part 101, so that it can directly sense the pressure generated when the earphone contacts the concha cavity, ensuring accurate monitoring of the main stress area of the ear. At the same time, in order to more comprehensively understand and control the pressure distribution during the entire clamping process, the pressure sensor can also be deployed at the second clamping part 203, i.e., the position where the clamping assembly 2 contacts the back of the ear. This dual monitoring design not only improves the range of pressure data collection, but also helps to more accurately assess the stability and comfort of the earphone in different wearing states. In the layout of the sensor, the principle of uniformity and reasonableness should be followed to ensure that each key clamping point is effectively covered. This means that whether it is the first clamping part 101 or the second clamping part 203, the distribution of the pressure sensor should be able to capture both local pressure changes and overall pressure trends, thereby achieving comprehensive and accurate monitoring of the clamping pressure. Such a design not only helps the earphone intelligent control system to make more accurate control decisions, but also effectively avoids discomfort caused by excessive or insufficient local pressure, further improving the user's wearing experience and health protection.

[0033] In some embodiments, the clamping assembly 2 includes a clamping piece 201 and a rotating shaft 202, the clamping piece 201 is rotatably connected with the main machine 1 through the rotating shaft 202, the rotating shaft 202 is connected with the power end of the driving assembly 3, and is key-connected with the clamping piece 201. The clamping piece 201 is the key part of the earphone that contacts the ear, and its shape, material and flexibility are carefully designed to provide the best wearing experience. Through the rotating shaft 202, the clamping piece 201 and the main machine 1 are rotatably connected, and this design allows the clamping piece 201 to be adjusted according to the contour of the ear when worn, so as to achieve the best fitting effect. The rotating shaft 202 plays a crucial role in the clamping assembly 2. It is not only a connecting bridge between the clamping piece 201 and the main machine 1, but also a key channel for power transmission of the driving assembly 3. By connecting with the power end of the driving assembly 3, the rotating shaft 202 can receive the driving force from the driving assembly 3, and then realize the opening and closing or adjustment action of the clamping piece 201. At the same time, the key connection between the rotating shaft 202 and the clamping piece 201 ensures stable power transmission and precise control of the clamping piece 201. This design not only improves the wearing comfort and stability of the earphone, but also brings more possibilities. For example, by adjusting the output parameters of the driving assembly 3, users can easily control the clamping force of the earphone to adapt to different wearing needs and scenarios. In addition, this adaptive adjustment design also helps to reduce the pressure on the ear, improving the user's wearing experience.

[0034] At the same time, the driving assembly 3 is configured to: when the pressure value detected by the pressure sensor is a, if a≥N1, the driving assembly 3 drives the clamping assembly 2 to move away from the main machine 1 to increase the clamping position 4; if a

[0035] In the above scheme, when the pressure value a detected by the pressure sensor reaches or exceeds the preset high pressure threshold N1, it usually means that the clamping force of the earphone on the ear is too large, which may cause discomfort to the user. At this time, the driving assembly 3 will receive the corresponding signal and drive the clamping assembly 2 to move away from the main machine 1. This action will effectively increase the clamping position 4, thereby reducing the pressure on the ear and ensuring the comfort of wearing.

[0036] On the contrary, when the pressure value a is lower than the preset low pressure threshold N2, it usually indicates that the clamping force of the earphone on the ear is too small, which may cause the earphone to be unstable. In this case, the driving assembly 3 will drive the clamping assembly 2 to move towards the main machine 1 to reduce the clamping position 4, thereby enhancing the stability of the earphone and ensuring good wearing effect in various activity scenarios.

[0037] It is worth noting that both the high pressure threshold N1 and the low pressure threshold N2 are carefully set based on a large amount of user data and wearing experience to ensure that the earphone can provide sufficient stability while not causing any discomfort to the user. In addition, these two thresholds can also be fine-tuned according to the user's personal preferences and ear characteristics, thus achieving a more personalized wearing experience.

[0038] Regarding the specific value range of N1 and N2, it is actually a complex problem involving user experience, earphone design, and material science, etc. Different earphone designs, user groups, and use scenarios may affect the value of N1 and N2.

[0039] In general, the value of N1 and N2 should be based on the following considerations:

[0040] User comfort: The value of N1 should be set above a pressure value that ensures the user does not feel excessive compression or discomfort when wearing the earphone. This usually needs to be determined through user testing, market research, and ergonomic principles. Similarly, the value of N2 should ensure that the earphone provides sufficient stability when worn, avoiding slipping or loosening, while not causing unnecessary compression to the user.

[0041] Earphone design: The material, structure, and clamping method of the earphone will affect the value of N1 and N2. For example, if the earphone uses soft materials and ergonomic design, a higher N1 value may be needed to ensure stability, as soft materials may reduce the clamping force to some extent.

[0042] Use scenario: Different use scenarios have different requirements for the clamping force of the earphone. For example, in the sports scenario, the user may need higher clamping force to ensure that the earphone does not slip due to sweat or movement; while in daily wear or office scenarios, the user may pay more attention to comfort, thus requiring lower N1 value and higher N2 value.

[0043] From general experience, the value of N1 can be set to a relatively high pressure value to ensure the stability and wearing effect of the earphone; while the value of N2 can be set to a relatively low but sufficient pressure value to keep the earphone from falling off.

[0044] Among them, specifically, for most over-ear headphones, N1 (high pressure threshold) can be set in the range of about 2-3 Newton (N) to ensure that when the clamping force of the earphone on the ear is too large, the drive assembly 3 can respond in time and adjust the clamping position 4, thereby reducing the pressure on the ear and improving the wearing comfort. This range is determined based on the general user's comfort feeling and the stability requirements of the earphone design. At the same time, N2 (low pressure threshold) can be set in the range of about 0.5-1.5 Newton (N) to ensure that the earphone can provide sufficient stability when worn, avoiding slipping or loosening. This range is also determined based on the user's demand for earphone stability in different activity scenarios. However, these value ranges are not absolute, but reference values obtained from general experience and user testing. In actual application, the specific values also need to be considered and adjusted according to the design characteristics of the earphone, user groups, and use scenarios, etc.

[0045] Further, the host 1 includes a signal processing module and a power module, the signal processing module is electrically connected to the pressure sensor and the drive assembly 3 respectively, and the power module is connected with the pressure sensor, the drive assembly 3, and the signal processing module through current delivery lines. The signal processing module is the brain of the earphone intelligent control mechanism, which is responsible for receiving real-time pressure data from the pressure sensor and analyzing and processing these data. By comparing with the preset pressure threshold, the signal processing module can judge whether the current clamping state meets the user's comfort requirements, and accordingly sends corresponding control instructions to the drive assembly 3. The power module provides stable power support for the entire earphone system, which establishes connection with the pressure sensor, the drive assembly 3, and the signal processing module through current delivery lines, ensuring that each functional module can obtain sufficient power supply when needed. This design not only improves the running efficiency of the earphone, but also helps to prolong the service life of the earphone.

[0046] Further, the outer surface of the host 1 is provided with a display module, and the inside is provided with a prompt module, the display module is electrically connected with the pressure sensor, and can be connected with external electronic equipment through wireless network, and the prompt module of the host 1 is electrically connected with the pressure sensor. The display module is located on the outer surface of the host 1, which can display the current earphone clamping force information on the ear through the electrical connection with the pressure sensor. This design allows users to intuitively understand the wearing state of the earphone, so as to adjust in time according to the individual comfort requirement. In addition, the display module also has the ability to connect with external electronic equipment through wireless network, which means that users can remotely view the clamping force data of the earphone through smart phones, tablet computers and other smart devices, and even remotely control. The cross-device interconnection function greatly improves the convenience and practicality of the earphone. The prompt module is located in the inside of the host 1, which is also electrically connected with the pressure sensor. When the clamping force of the earphone on the ear exceeds the preset comfortable range, the prompt module will start immediately, and warn the user through sound, light or vibration. This design not only helps users to find and correct the improper wearing problem in time, but also effectively avoids the discomfort or damage of the ear caused by long-term wearing.

[0047] It is worth mentioning that the design of the display module and the prompt module fully considers the actual needs and operation habits of users. For example, the interface design of the display module is simple and easy to understand and operate; the warning mode of the prompt module is flexibly set according to the user's preference and scene requirement, so as to ensure that the user can receive effective prompt information in the first time.

[0048] Optionally, the pressure sensor is a micro thin film pressure sensor, a micro piezoresistive pressure sensor or a micro capacitive pressure sensor. The micro thin film pressure sensor adopts thin film technology, has the advantages of small size, light weight and high sensitivity, and can quickly respond to external pressure changes and convert them into electrical signals for transmission. Due to its good flexibility and strong adaptability, it is very suitable for occasions requiring high-precision pressure measurement, such as ear-clamping earphones, for real-time monitoring of the clamping force of the earphone on the ear.

[0049] The micro piezoresistive pressure sensor works based on the piezoresistive effect, that is, when the material is subjected to pressure, its resistance value will change. By measuring this resistance change, the pressure information can be indirectly obtained. The piezoresistive sensor has the advantages of wide measurement range, high precision and good stability. In addition, it also has the characteristics of low power consumption, easy integration and miniaturization, which is very suitable for small electronic devices such as ear-clamping earphones. In the ear-clamping earphone, the piezoresistive sensor can monitor the clamping force of the earphone on the ear in real time, and adjust as needed to ensure the comfort and stability of wearing.

[0050] Miniature capacitive pressure sensors detect pressure based on changes in capacitance. When external pressure is applied to the sensor, it causes a change in the distance or area between the capacitor plates, which changes the capacitance value. By measuring this capacitance change, pressure information can be obtained. Capacitive sensors have high sensitivity, fast response speed, good stability, and other advantages. At the same time, it also has good anti-interference ability and environmental adaptability, and can work stably in various complex environments. In the ear-clamping earphone, the capacitive sensor can be used to monitor the clamping force of the earphone on the ear in real time, and provide accurate pressure data to help users adjust the wearing state or optimize the design of the earphone.

[0051] Miniature thin-film pressure sensors, miniature piezoresistive pressure sensors, and miniature capacitive pressure sensors are all excellent choices for ear-clamping earphones. They each have unique characteristics and advantages, and can be selected according to specific application requirements and design requirements.

[0052] In addition, the drive assembly 3 is a drive motor or an electric push rod. The drive motor is a device that converts electrical energy into mechanical energy, with the advantages of small size, light weight, high power density, easy control, etc. It can achieve rotary motion or linear motion by changing the direction and size of the current, thereby driving the clamping assembly 2 to move. The drive motor can be installed inside the earphone and connected to the clamping assembly 2 through a transmission mechanism such as a gear or a lead screw. When the pressure sensor detects that the clamping force exceeds the preset range, the signal processing module will send instructions to the drive motor to drive the clamping assembly 2 to move to adjust the size of the clamping position 4.

[0053] The electric push rod is a device that directly converts electrical energy into linear motion, with the advantages of simple structure, easy installation, large thrust, high control precision, etc. It can achieve the extension and retraction of the push rod by changing the input voltage or current of the motor, thereby driving the clamping assembly 2 to move. The electric push rod can be directly connected to the clamping assembly 2, or connected to the clamping assembly 2 through a transmission mechanism such as a connecting rod. When the pressure sensor detects that the clamping force does not meet the requirements, the signal processing module will send instructions to the electric push rod to drive the clamping assembly 2 to move to achieve the purpose of adjusting the clamping position 4.

[0054] In selection, specific application requirements, space limitations, control precision, power consumption, and cost factors need to be considered comprehensively. Through reasonable selection and design, intelligent control of clamping force can be achieved, and the wearing comfort and stability of the earphone can be improved.

[0055] It is particularly important to note that in the software algorithm of the earphone, a pressure data processing algorithm is included, which is a smart algorithm designed to improve the wearing experience of the earphone. It runs on the signal processing unit or microprocessor of the earphone and can process the data collected by the pressure sensor in real time. The algorithm first obtains the pressure information of the ear clamp part in real time through a high-precision pressure sensor, and performs filtering, denoising and other preprocessing operations on these data to ensure the accuracy and reliability of the data. Then, the algorithm uses the calibration data of the sensor to convert the raw data into the actual ear clamp pressure value, thereby achieving accurate measurement of the ear clamp pressure.

[0056] To meet the individual needs of different users, the algorithm also has the function of setting individual pressure range. Users can input their preferences such as ear sensitivity, wearing habits, etc. through mobile applications or other means, and the algorithm will automatically calculate and set the appropriate individual pressure range based on these information and the internal default pressure range (based on a large amount of user data). In addition, the algorithm can dynamically adjust the pressure range based on user feedback and use history to better adapt to the user's ear characteristics and wearing needs.

[0057] The pressure data processing algorithm of the ear clamp earphone not only has accurate pressure calculation capability, but also provides real-time monitoring and abnormal reminding function. The algorithm can calculate the current ear clamp pressure in real time and compare it with the preset individual pressure range. When it detects that the ear clamp pressure has been continuously exceeding the preset range (too high or too low) for a period of time, the algorithm will immediately start the abnormal detection mechanism.

[0058] In order to effectively remind users to adjust the ear clamp force, the algorithm uses a variety of reminding methods such as sound, light, vibration, etc. These reminding methods can be intelligently selected according to the degree and duration of abnormal pressure to ensure the timeliness and effectiveness of the reminder. At the same time, the algorithm allows users to feedback on the reminder through the earphone or mobile application, so as to continuously optimize the reminder mechanism and improve the user experience.

[0059] In addition to real-time monitoring and reminding functions, the algorithm also has the ability of self-learning and optimization. It uses machine learning algorithms to analyze user preferences and use history, continuously optimizing pressure range settings and reminder mechanisms to better adapt to changing user needs. In addition, the algorithm also supports online update function, which can receive and apply the latest update package to realize the continuous upgrading and optimization of the algorithm.

[0060] In terms of safety and stability, the algorithm monitors the working state of the sensor and control device in real time, and takes measures such as stopping adjustment and issuing warnings as soon as abnormalities are found, to ensure the safety of the user's wearing. At the same time, the algorithm also sets a maximum ear clamping force limit to prevent harm to the user due to excessive adjustment. Through these measures, the algorithm provides an excellent wearing experience and safety for the ear clamping earphone.
