Under such an understanding, all specific subordinate specific definitions of the nouns or methods should be regarded as the content of the present utility model, and should not be narrowly understood or prejudicially interpreted on the grounds that the specific definition is not disclosed in the specification. Similarly, on the premise that it can be logically realized, the order of the steps in the method is flexible and changeable, and all specific subordinate specific definitions in the broad concepts of various nouns or methods belong to the protection scope of the present utility model.

[0025] The main solution of the embodiments of the present application is: by arranging the antenna part in the housing, then connecting and conducting the path between the circuit board and the antenna part through a conductive member, and a touch sensing part is arranged on the housing. When the touch sensing part is triggered by a user, a corresponding touch signal is generated, and the touch sensing part is electrically connected to the signal transmission member to output the touch signal to the circuit board.

[0026] In existing intelligent wearable devices with touch control functions, such as true wireless stereo (TWS) earphones, the touch sensing circuit and the antenna are usually arranged in the housing. As the size continues to shrink, in order to optimize the touch control experience, the touch sensing area often requires a large area, which inevitably leads to a reduction in the effective area of the antenna. This design conflict may cause mutual interference between the two, thus having a negative impact on the performance of the antenna.

[0027] The present application provides a solution, thereby realizing the optimized coordination of the touch control function and the antenna performance, and being able to better improve the overall performance of the antenna assembly.

[0028] Refer to Figures 1 to 3, in an embodiment of the present utility model, the antenna assembly includes a circuit board 100, a housing 200, an antenna portion 300, a conductive member 410, and a signal transmission member 420, wherein:

[0029] The housing 200 has a touch sensing portion 210 and an antenna portion 300. The touch sensing portion is configured to generate a corresponding touch signal when triggered by a user; the conductive member 410 is electrically connected to the circuit board 100 and the antenna portion 300 respectively, and the conductive member 410 is used to conduct the path between the circuit board 100 and the antenna portion 300; the signal transmission member 420 is electrically connected to the touch sensing portion 210 and outputs the touch signal to the circuit board 100.

[0030] In this embodiment, the material of the housing 200 can be a conductive material, such as metal or plastic with a conductive coating, to ensure that the touch sensing portion 210 can effectively sense the touch action of the user. The antenna portion 300 can adopt a flexible printed circuit (FPC) antenna portion 300, or an equivalent antenna portion 300 is formed by using the housing 200, or is etched by a laser engraving method, so as to adapt to the shape of the housing 200 and reduce the influence on the overall size of the antenna assembly.

[0031] Among them, the antenna portion 300 and the touch sensing portion 210 can be integrally arranged. The integral arrangement means that the antenna portion 300 and the touch sensing portion 210 overlap on the housing or use the same circuit. Through the integral arrangement, space can be saved and channel multiplexing can be achieved, so that while the area of the touch sensing portion 210 increases, the effective area of the antenna portion 300 will not decrease.

[0032] Since the touch signal and the antenna signal are low-frequency signals and high-frequency signals respectively, by adopting the integral arrangement method, the touch signal and the antenna signal can be conducted through the conductive member 410 and the signal transmission member 420 respectively, and the corresponding post-stage filtering circuit is used to filter different signals, so as to achieve accurate identification and processing of the touch signal and the antenna signal. The post-stage filtering circuit can be designed as a low-pass filter and a high-pass filter, which are respectively used to separate the low-frequency touch signal and the high-frequency antenna signal, so as to optimize the antenna design of the TWS antenna assembly with touch control, so as to achieve a better cooperative working effect between the touch sensing area and the antenna and improve the overall performance of the antenna assembly.

[0033] In addition, in another implementation, the antenna unit 300 and the touch sensing unit 210 can be separately arranged. The separate arrangement can be achieved by hierarchical arrangement or zonal arrangement. Among them, the hierarchical arrangement is to arrange the antenna unit 300 and the touch sensing unit 210 on different layers of the housing 200 to reduce the interference between the two. In the case of hierarchical arrangement, the touch sensing unit 210 can be located on the inner layer of the housing 200, while the antenna unit 300 can be arranged on the outer layer of the housing 200, so as to ensure better signal reception and transmission effects of the antenna unit 300. The separate arrangement can provide greater design flexibility and allow the antenna unit 300 and the touch sensing unit 210 to be optimized respectively.

[0034] Among them, an isolation component, such as an outer housing, a shielding cover or an insulating coating, can also be provided on the housing 200 to prevent the user from directly contacting the conductive material when the user touches the touch sensing unit 210, so as to avoid the antenna signal being interfered and weakened or the signal being lost.

[0035] Among them, the touch sensing unit 210 can be designed into multiple independent sensing areas to perform corresponding control functions. For example, touching the left edge of the housing 200 can be used to increase the volume, while touching the right edge can be used to decrease the volume to meet different operation needs of the user.

[0036] Among them, the antenna unit 300 can be designed to have multiple radiation units, and these radiation units are connected to the circuit board 100 through the conductive member 410. By reasonably arranging the radiation units, the signal reception and transmission capabilities of the antenna unit 300 can be improved without affecting the area of the touch sensing unit 210.

[0037] In this embodiment, by arranging the antenna unit 300 on the housing 200, then connecting and conducting the path between the circuit board 100 and the antenna unit 300 through the conductive member 410, and arranging the touch sensing unit 210 on the housing 200, when the touch sensing unit 210 is triggered by the user, a corresponding touch signal is generated, and it is electrically connected to the touch sensing unit 210 through the signal transmission member 420. When the user touches the housing 200, the touch signal is output to the circuit board 100, thereby realizing the optimized coordination of the touch control function and the antenna performance, and being able to better improve the overall performance of the antenna assembly.

[0038] In this embodiment, the antenna assembly can be applied to various wireless communication devices, including but not limited to smart phones, tablet computers, laptop computers, headphones, wireless routers, vehicle-mounted communication systems, and Internet of Things (IoT) devices. The design of this antenna assembly aims to provide high-efficiency signal transmission and reception while maintaining a small size and weight to adapt to the space limitations of modern portable devices.

[0039] Optionally, referring toFigure 1 , Figure 3 and Figure 4 , another embodiment of the present utility model provides an antenna assembly. Based on the above Figures 1 to 3 illustrated embodiment, the antenna assembly includes a metal part 400, wherein:

[0040] The conductive part 410 and the signal transmission part 420 are integrally provided on the metal part 400.

[0041] In this embodiment, the metal part 400 is an independent component, and its surface can be specially treated to improve the conductivity. The use of the metal part 400 not only helps to improve the sensitivity of the touch sensing part 210, but also can be used as a part of the antenna part 300 to enhance the signal receiving and transmitting effects.

[0042] By integrally setting the conductive part 410 and the signal transmission part 420, the structure of the antenna assembly can be greatly simplified. At the same time, through the integral setting, the signals transmitted by the antenna part 300 and the touch signals are both transmitted through the metal part 400, reducing the wiring complexity on the circuit board 100, reducing the assembly steps and costs, and thus improving the overall stability and reliability.

[0043] Among them, the metal part 400 can be made of gold, silver, copper or other metal materials with good conductivity to ensure the high efficiency and stability of signal transmission.

[0044] In addition, the metal part 400 can be designed to have a certain elasticity so that it can make good contact with the circuit board 100 and the antenna part 300 during the assembly process of the antenna assembly. This elastic design can also absorb external shocks to a certain extent and protect the internal circuit from damage.

[0045] In this embodiment, the shape and size of the metal part 400 can be adjusted according to actual needs to adapt to antenna assembly housings 200 of different shapes and sizes. For example, the metal part 400 can be designed in a ring shape or a strip shape to cover a specific area of the housing 200, thereby achieving more precise touch control.

[0046] Optionally, referring to Figure 5 , another embodiment of the present utility model provides an antenna assembly. Based on the above Figure 1 , Figure 3 and Figure 4 illustrated embodiment, the antenna assembly includes an antenna radio frequency circuit 500 and a touch circuit 600, wherein:

[0047] The antenna radio frequency circuit 500 and the touch circuit 600 are respectively electrically connected to the metal part 400.

[0048] In this embodiment, the antenna RF circuit 500 processes the RF signals received by the antenna unit 300, while the touch circuit 600 processes the signals from the touch sensing unit 210. By electrically connecting these two circuits to the metal part 400 respectively, more efficient signal processing and transmission can be achieved, and the two different signals are separated to avoid signal mistransmission or channel interference.

[0049] Among them, the antenna RF circuit 500 can be designed to have multiple input / output ports to support signal processing in different frequency bands. In this way, the antenna assembly can support multiple wireless communication standards simultaneously, such as Bluetooth, Wi-Fi, and NFC, etc. In addition, the antenna RF circuit 500 can also include components such as filters and amplifiers to improve the purity and intensity of the signals.

[0050] Among them, the touch circuit 600 can include a microcontroller, or a low-pass filter circuit 520, or other processing units, which are used to analyze the signals from the touch sensing unit 210 and convert them into corresponding control instructions. The touch circuit 600 can also have the function of learning and memorizing the user's operation habits, so as to provide a more personalized user experience.

[0051] In this embodiment, the antenna RF circuit 500 and the touch circuit 600 are electrically connected through the metal part 400, and fast signal transmission and processing can be achieved. As a connection medium, the metal part 400 not only ensures the stability and reliability of signal transmission, but also can reduce electromagnetic interference and improve the overall performance.

[0052] In addition, the metal part 400 can also be designed to have a shielding function to prevent external electromagnetic interference from affecting the normal operation of the antenna RF circuit 500 and the touch circuit 600. To improve the signal quality and stability of the antenna assembly.

[0053] Optionally, at least part of the housing 200 is set as the antenna unit, or the antenna unit 300 is formed on the housing 200 through a laser engraving process.

[0054] In this embodiment, at least part of the housing 200 is set as the antenna unit, that is, the antenna unit 300 is integrally provided on the housing 200, that is, the housing 200 is regarded as an equivalent antenna, thus eliminating the need for an additional antenna unit 300 component and simplifying the structure of the antenna assembly. It not only reduces the weight of the antenna assembly, but also reduces the production cost. The integrated setting can also make the materials of the antenna unit 300 and the housing 200 closely combined, thereby improving the durability and stability of the antenna assembly.

[0055] Among them, the antenna portion 300 formed on the housing 200 through the laser engraving process can achieve the layout of the antenna portion 300 without adding additional components. The laser engraving process can form a conductive path on the surface of the housing 200, thereby forming the structure of the antenna portion 300. This implementation method not only saves space, but also maintains the aesthetics of the antenna assembly, while reducing the impact on the overall size of the antenna assembly.

[0056] In addition, in another implementation, the antenna portion 300 is provided with an FPC as an antenna and is fixed to the housing 200 through a fixing member. The design of fixing the FPC antenna to the housing 200 through a fixing member enables the FPC antenna to be designed and manufactured independently of the housing 200, and then connected to the housing 200 through a fixing member, so that the antenna portion 300 can be individually tested and optimized during the manufacturing process to ensure that its performance reaches the best. At the same time, the use of the FPC antenna portion 300 can adapt to different shapes and sizes of the housing 200, providing better signal coverage. If an FPC antenna is used, the touch sensing portion 210 and the antenna portion 300 can be more flexibly arranged at different positions of the housing 200 to achieve the best signal reception and transmission effects, and at the same time, a better cooperative working effect can be achieved between the touch sensing area and the antenna, thereby improving the overall performance of the antenna assembly. In addition, the flexible characteristic of the FPC antenna enables it to better conform to the shape of the housing 200, thereby minimizing signal loss and interference.

[0057] In this embodiment, the integrated setting between the antenna portion 300 and the housing 200, the formation of the antenna portion 300 through the laser engraving process, or the use of the FPC antenna portion 300 are all aimed at improving the signal reception and transmission capabilities of the antenna assembly, while maintaining the aesthetics and durability of the antenna assembly. Through the above design methods, the antenna assembly can provide stable and reliable performance in various usage environments, meeting the user's requirements for high-quality audio experience.

[0058] Optionally, referring to Figure 3 , another embodiment of the present invention provides an antenna assembly. Based on the above Figure 1 , Figure 3 and Figure 4 shown embodiments, the metal member 400 is disposed in the accommodation space between the circuit board 100 and the housing 200. When the user touches the housing 200, the touch signal is transmitted to the circuit board 100 through the metal member 400.

[0059] In this embodiment, the setting of the metal member 400 not only provides a good electrical connection channel for the touch sensing portion 210, but also can be used as a part of the antenna portion 300 to enhance the signal reception and emission effects. By placing the metal member 400 in the accommodation space between the circuit board 100 and the housing 200, the limited space can be effectively utilized while ensuring the stability and reliability of signal transmission.

[0060] In this embodiment, the shape and size of the metal part 400 can be adjusted according to actual needs to adapt to antenna component housings 200 of different shapes and sizes. For example, the metal part 400 can be designed as a ring or a strip to cover a specific area of the housing 200, thereby achieving more precise touch control. In addition, the metal part 400 can also be designed to have a certain elasticity so that it can make good contact with the circuit board 100 and the antenna part 300 during the assembly of the antenna component.

[0061] Optionally, referring to Figure 6 , another embodiment of the present utility model provides an antenna component. Based on the above Figure 1 illustrated embodiment, the antenna radio frequency circuit 500 includes an antenna matching circuit 510, a filtering circuit 520, and a radio frequency chip 530, where:

[0062] The input end of the antenna matching circuit 510 is electrically connected to the conductive part 410. The antenna matching circuit 510 is used to tune the signal of the antenna part 300 transmitted by the antenna part 300; the input end of the filtering circuit 520 is connected to the output end of the antenna matching circuit 510. The filtering circuit 520 is used to select and pass the high-frequency signal of the antenna part 300; the input end of the radio frequency chip 530 is connected to the output end of the filtering circuit 520 to receive the corresponding signal of the antenna part 300 transmitted by the antenna part 300.

[0063] In this embodiment, the combined design of the antenna matching circuit 510, the filtering circuit 520, and the radio frequency chip 530 ensures the accuracy and efficiency of signal transmission during the process. The antenna matching circuit 510 optimizes the transmission efficiency of the antenna part 300 by adjusting the impedance matching, thereby improving the quality of signal transmission and reception. The filtering circuit 520 effectively suppresses noise and interference by selectively allowing signals within a specific frequency range to pass through, ensuring the purity of the signal. The radio frequency chip 530, as the core processing unit, is responsible for processing and decoding the signals received by the antenna part 300 and converting them into available data or audio signals. Among them, the radio frequency chip 530 can adopt a radio frequency chip 530 integrated with wireless reception and wireless output capabilities, such as an NFC chip or a Bluetooth chip, etc.

[0064] Optionally, referring to Figure 8 , yet another embodiment of the present utility model provides an antenna component. Based on the above Figure 6 illustrated embodiment, the antenna matching circuit 510 includes a first capacitor C124, a first inductor R72, and a second capacitor C126, where:

[0065] The first end of the first capacitor C124 is electrically connected to the conductive member 410, and the second end of the first capacitor C124 is grounded; the first end of the first inductor R72 is connected to the first end of the first capacitor C124, and the second end of the first inductor R72 is connected to the input end of the radio frequency chip 530; the first end of the second capacitor C126 is connected to the second end of the first inductor R72, and the second end of the second capacitor C126 is grounded.

[0066] In this embodiment, the antenna matching circuit 510 can be a π-type matching circuit. By reasonably selecting the parameters of the first capacitor C124, the first inductor R72, and the second capacitor C126, precise matching of the impedance of the antenna unit 300 can be achieved. This design of the antenna matching circuit 510 helps to improve the transmission efficiency of the antenna unit 300 and ensure good performance of the signal in different frequency bands.

[0067] Among them, the first capacitor C124 and the second capacitor C126 play a role in blocking the DC component in the circuit while allowing high-frequency signals to pass through. The first inductor R72 is mainly responsible for adjusting the resonance frequency of the antenna unit 300. Through combination with the capacitor, optimization of signals in specific frequency bands can be achieved. This π-type matching circuit design is simple and efficient and can meet the requirements of various wireless communication standards.

[0068] In this embodiment, the parameters of the antenna matching circuit 510 can be adjusted according to the actual use environment and the characteristics of the antenna unit 300 to achieve the best matching effect. For example, by changing the values of the inductor and capacitor, the resonance frequency of the antenna unit 300 can be adjusted, thereby optimizing the signal reception and transmission performance. In addition, the matching circuit can be designed to be adjustable for fine-tuning during the production process of the antenna assembly to ensure that each antenna assembly can meet the best performance standards.

[0069] In practical applications, the design of the antenna matching circuit 510 also needs to consider the physical structure and material characteristics of the antenna assembly. For example, the material and shape of the antenna assembly housing 200 may affect the resonance frequency and radiation efficiency of the antenna unit 300. Therefore, these factors can be comprehensively considered when designing the matching circuit to ensure the coordinated operation of the circuit and the antenna unit 300.

[0070] Optionally, referring to Figure 8 , another embodiment of the present utility model provides an antenna assembly. Based on the above Figure 6 shown embodiment, the filtering circuit 520 includes a filter, where:

[0071] The input end of the filter is connected to the output end of the antenna matching circuit 510, and the output end of the filter is connected to the input end of the radio frequency chip 530. The filter is used to select and pass the high-frequency signals of the antenna unit 300.

[0072] In this embodiment, the filter can be, for example, Figure 8 the SAW filter U11 (Surface Acoustic Wave Bandpass Filter) shown in the figure to improve the accuracy of signal processing. With its characteristics of high selectivity and low insertion loss, the SAW filter can effectively filter out unwanted frequency components and ensure the purity and stability of the signal. This type of filter is particularly suitable for wireless communication devices. For example, in TWS earphones, it can ensure the transmission of high-quality audio signals within a limited frequency band.

[0073] In addition, the filter can also be an LC filter, which consists of inductance (L) and capacitance (C) components. It filters signals of specific frequencies through their resonance characteristics to suppress interference signals. The LC filter has high flexibility in design and can adjust its parameters according to different application requirements to achieve the best filtering effect. In some cases, to improve the filtering performance, a cascaded multi-stage LC filter can be used to enhance the suppression ability of specific frequency bands.

[0074] Among them, the bandwidth of the filter can be adjusted according to the wireless communication standard supported by the antenna assembly to adapt to different operating frequency ranges. For example, for TWS earphones, the bandwidth of the filter is usually set between 2.4 GHz and 2.5 GHz, which is a commonly used frequency band for Bluetooth technology. By precisely controlling the bandwidth, the filter can effectively suppress interference from adjacent channels and improve the communication quality of the antenna assembly.

[0075] In addition, the compact design of the filter makes it very suitable for integration inside earphones or small audio devices without taking up too much space. Its low power consumption also means that it has little impact on the battery life of the antenna assembly, which helps to maintain the long-term use of the antenna assembly.

[0076] Of course, the type of the filter can also be other types of filters, not limited to the above two types of filters. For example, ceramic filters or digital filters. Among them, ceramic filters utilize the characteristics of piezoelectric ceramic materials and achieve frequency selection through their mechanical vibration. This type of filter has good temperature stability and a high Q value and can maintain stable performance within a wide temperature range. Ceramic filters are usually used for intermediate frequency (IF) filtering, but can also be designed for radio frequency (RF) applications according to the design. Due to its small size, low cost, and high reliability, ceramic filters are widely used in portable devices.

[0077] The digital filter is implemented by a digital signal processor (DSP) or a microcontroller (MCU), which can provide extremely high flexibility and accuracy. The digital filter can be programmed to achieve various filtering characteristics, such as low-pass, high-pass, band-pass, and band-stop, etc., and can also dynamically adjust the filtering parameters according to the actual signal situation. In addition, the digital filter can also implement complex signal processing algorithms, such as adaptive filtering and noise cancellation, so as to improve the signal quality.

[0078] Optionally, referring to Figure 7 , another embodiment of the present invention provides an antenna assembly. Based on the above Figures 1 to 3 shown embodiment, it includes a touch circuit 600, wherein:

[0079] The input end of the touch circuit 600 is electrically connected to the signal transmission member 420, and the touch circuit 600 is used to select and pass the touch signal.

[0080] In this embodiment, the touch circuit 600 is used to match the touch signal output by the user's operation on the touch sensing part 210 to filter out the high-frequency signal of the antenna part 300 and unnecessary noise. By providing the touch circuit 600, the touch signal can be selected and passed better, thereby improving the interaction experience of the antenna assembly. The touch circuit 600 is electrically connected to the touch sensing part 210 through the signal transmission member 420, ensuring the sensitivity and accuracy of the touch operation. Among them, the touch sensing part 210 can adopt capacitive touch sensing technology. When the user's finger touches, due to the human body capacitance effect, the capacitance value changes and is transmitted to the touch circuit 600 through the signal transmission member 420.

[0081] In order to improve the stability and accuracy of the touch circuit 600, the touch circuit 600 can also integrate a noise suppression function to filter out the noise generated by environmental electromagnetic interference or the internal circuit of the antenna assembly. In addition, the design of the touch circuit 600 can also consider the physical structure and material characteristics of the antenna assembly to ensure the sensitivity and response speed of the touch sensing part 210 area.

[0082] Optionally, referring to Figure 8 , yet another embodiment of the present invention provides an antenna assembly. Based on the above Figure 7 shown embodiment, the touch circuit 600 includes a second inductor L27, a first resistor R121, and a touch chip, wherein:

[0083] The first end of the second inductor L27 is electrically connected to the signal transmission member 420; the first end of the first resistor R121 is connected to the second end of the second inductor L27; the input end of the touch chip is connected to the second end of the first resistor R121.

[0084] In this embodiment, the second inductor L27 and the first resistor R121 play key roles in the touch circuit 600. The second inductor L27 is mainly responsible for suppressing high-frequency noise and preventing it from interfering with the normal transmission of touch signals. By selecting an appropriate inductance value, high-frequency interference can be effectively filtered out to ensure the purity of touch signals. The first resistor R121 plays a role in current limiting, protecting the touch chip from overcurrent damage and stabilizing the level of touch signals at the same time.

[0085] Among them, the touch chip, as the core component of the touch circuit 600, is responsible for receiving and processing signals from the touch sensing unit 210. It can recognize the user's touch actions and convert them into corresponding control instructions. The touch chip usually has the characteristics of high sensitivity and fast response to ensure a smooth interaction experience for users when using the antenna assembly.

[0086] Among them, the touch chip can be a dedicated touch control integrated circuit with multiple touch modes and sensitivity adjustment functions.
