[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, in combination with the drawings, the preferred embodiments of the present utility model will be described in detail.

[0027] An embodiment of the present utility model provides a headset, as Figures 1 to 5 shown. The headset includes a housing 1, a main control circuit board 3, and a carrier sheet 4; the housing 1 includes a middle housing 11 and a rear housing 12. The main control circuit board 3 is installed in the middle housing 11. The rear housing 12 corresponds to the main control circuit board 3 and covers the middle housing 11. The carrier sheet 4 is installed between the main control circuit board 3 and the rear housing 12.

[0028] An antenna pin 31 is provided on the main control circuit board 3, and an antenna is provided on the carrier sheet 4. The antenna has an antenna contact corresponding to the antenna pin 31; the antenna contact abuts against the antenna pin 31.

[0029] In the headset of the present utility model, a carrier sheet 4 is provided between the rear housing 12 and the middle housing 11, so that the carrier sheet 4 is located between the main control circuit board 3 and the rear housing 12. An antenna pin 31 is provided on the main control circuit board 3, and an antenna is provided on the carrier sheet 4. The antenna has an antenna contact corresponding to the antenna pin 31. After the rear housing 12 is covered on the middle housing 11, while the installation of the carrier sheet 4 is completed, the antenna contact abuts against the antenna pin 31, thereby completing the connection between the antenna and the antenna pin 31. Since the antenna is provided on the carrier sheet 4, the carrier sheet 4 provides an independent design space for the antenna and is not attached to the main control circuit board 3 and affected by the main control circuit board 3. Therefore, the design freedom is high and the antenna design difficulty is reduced.

[0030] Moreover, since the antenna is provided on the carrier sheet 4, the carrier sheet 4 realizes a non-integral connection with the antenna pin 31 through the antenna contact. The connection between the carrier sheet 4 and the main control circuit board 3 is detachable. During assembly, after the carrier sheet 4 and the main control circuit board 3 are respectively installed, covering the rear housing 12 on the middle housing 11 can complete the installation and connection of the antenna while installing the rear housing 12. The assembly is convenient and the subsequent disassembly is also convenient.

[0031] Specifically, on a Bluetooth headset, the antenna is responsible for wirelessly transmitting the audio signal in the Bluetooth headset to a paired device, such as a smartphone, a tablet, or other audio sources. In addition to transmitting signals, the antenna can also be responsible for receiving signals from the paired device to ensure two-way communication of the audio stream. The technical solution of the present utility model is particularly applicable to headsets (TWS+ANC dual-feed noise-canceling headsets) that incorporate True Wireless Stereo (TWS) technology and Active Noise Canceling (ANC) function. The middle shell 11 and the rear shell 12 can be further bonded by glue, and the main control circuit board 3 can be installed in the middle shell 11 by screws, limit posts, etc.

[0032] The antenna pins 31 include an antenna signal pin 311 and an antenna ground pin 312, and there are two antenna contacts corresponding to the antenna signal pin 311 and the antenna ground pin 312. The antenna signal pin 311 is the part used to transmit or receive wireless signals. In the antenna system of the headset, the antenna signal pin 311 transmits audio signals or other data signals for communication with other devices, carrying the signal transmission function from the headset to external devices (such as smartphones or other audio sources). The antenna ground pin 312 is used to form a complete circuit loop to ensure the correct transmission and reception of signals. In the headset antenna system, the ground pin provides a reference point and return path for the circuit, ensuring that the signal can complete the loop smoothly. The ground pin also helps to reduce interference and noise in the circuit and improve the anti-interference ability of the entire system. The antenna signal pin 311 and the antenna ground pin 312 together constitute the signal transmission and loop closing parts in the antenna system. The antenna signal pin 311 is responsible for signal transmission and reception, while the antenna ground pin 312 ensures the correct flow and stability of the signal in the circuit. Both together ensure the normal operation of the antenna system and the effectiveness of signal transmission. And in this solution, the connection with the antenna signal pin 311 and the antenna ground pin 312 is achieved by setting two antenna contacts on the antenna.

[0033] Specifically, the antenna signal pin 311 and the antenna ground pin 312 are elastic pins. Due to their elastic force during the connection process, the elastic pins can provide a firm contact, ensuring the stability and quality of signal transmission and reducing problems caused by poor contact. Moreover, the elastic pins elastically pressing against the carrier sheet 4 can also play a role in pressing and fixing the carrier sheet 4. The elastic pins are specifically metal elastic pins. The metal elastic pins have good electrical conductivity, can effectively transmit signals, and reduce the resistance during signal transmission, thereby improving the stability and reliability of signal transmission.

[0034] The carrier 4 is an FPC. The FPC (Flexible Printed Circuit) is flexible, capable of adapting to the design requirements of various shapes and sizes. At the same time, it is lightweight and does not add too much weight. It can be bent and folded according to the design needs to adapt to complex mechanical structure designs. Applied to this solution, it can be designed and installed between the rear shell 12 and the middle shell 11 more easily. Specifically, the shape of the FPC can adapt to the shape of the rear shell 12.

[0035] Further, a touch area 41 for touching the earphone is also provided on the carrier 4, and connection pins 33 are provided at the electrical connection contacts corresponding to the touch area 41 on the main control circuit board 3; the electrical connection contacts of the touch area 41 are abutted against the connection pins 33. The setting of the touch area 41 enables the user to control the earphone through touch operations, improving the convenience and intuitiveness of the operation and enhancing the user experience. Integrating the touch area 41 on the carrier 4 can save space and make more efficient use of the internal space of the earphone, which is beneficial to a more compact design. The connection pins 33, as the electrical connection points on the main control circuit board 3 corresponding to the touch area 41, play a role in connecting the electrical connection contacts of the touch area 41 on the carrier 4, realizing the electrical connection between the touch area 41 and the main control circuit board 3, ensuring the transmission quality and stability of the touch signal, and thus guaranteeing the accuracy and reliability of the touch function. Specifically, when in use, the user can control the earphone by touching at the position of the rear shell 12 corresponding to the touch area 41. For example, a single click is for play / pause switching, answering a call (left earphone), hanging up a call (right earphone), a double click is for switching to the previous track (left earphone), switching to the next track (right earphone), a triple click is for waking up the voice assistant of the mobile phone (left earphone), switching the game mode (right earphone), and a long press for 1 second is for rejecting an incoming call. Of course, different touch methods can also be designed according to actual control needs, which will not be elaborated here. Specifically, the touch area 41 can be provided with a capacitive touch sensor to realize the touch function of the touch area 41.

[0036] In an optional embodiment, the touch area 41 is located at one end of the carrier 4, and the antenna contacts are located at the other end of the carrier 4. By separately arranging the touch area 41 and the antenna contacts at both ends of the carrier 4, the space of the carrier 4 can be utilized to the maximum extent, ensuring the layout of different functional modules within the limited space of the carrier 4. Separately arranging the touch area 41 and the antenna contacts can also reduce the risk of electromagnetic interference between them, reducing the interference between the two, especially the interference to the antenna, and improving the stability and reliability of the overall earphone system.

[0037] Such as Figure 2 、 Figure 4 and Figure 5As shown in the figure, a limiting post 121 is provided on the inner wall surface of the rear shell 12, and a limiting hole 42 is provided on the carrier sheet 4. The carrier sheet 4 is mounted on the limiting post 121 through the limiting hole 42. Through the design of the limiting post 121 and the limiting hole 42, accurate positioning can be achieved, the position of the carrier sheet 4 is fixed during the assembly process, ensuring the correct alignment of the carrier sheet 4 and its cooperation with the main control circuit board 3, effectively preventing unnecessary movement or shaking of the carrier sheet 4 during use, and ensuring the structural stability of the earphone. Specifically, two limiting holes 42 are arranged at intervals along the length direction of the carrier sheet 4, and the limiting posts 121 are correspondingly arranged.

[0038] The housing 1 further includes a front shell 13, and the front shell 13 and the middle shell 11 are fitted and installed; a microphone 32 is provided at one end of the main control circuit board 3 away from the front shell 13, and a first avoidance notch 43 is provided on the carrier sheet 4 at one end corresponding to the microphone 32 away from the front shell 13. The setting of the first avoidance notch 43 can play a role in the carrier sheet 4 avoiding the microphone 32, preventing the carrier sheet 4 from pressing the microphone 32 when the assembly may not be in place. The microphone 32 (Microphone) is a component on the earphone for receiving sound. The front shell 13 and the middle shell 11 are fitted and installed to form a sound cavity, and necessary parts of the earphone, such as a battery, a speaker, and a noise reduction microphone 32, can be further arranged in the sound cavity. The battery, the speaker, and the noise reduction microphone 32 are electrically connected to the main control circuit board 3, and conventional technologies can be adopted, which will not be elaborated here.

[0039] In an optional embodiment, a limiting rib 122 is provided at one end of the rear shell 12 close to the front shell 13, a limiting groove 111 is provided on the middle shell 11 corresponding to the limiting rib 122, and the limiting rib 122 is embedded in the limiting groove 111; a second avoidance notch 44 is provided on the carrier sheet 4 at one end corresponding to the limiting rib 122 close to the front shell 13. Through the design of the limiting rib 122 and the limiting groove 111 in this solution, accurate alignment between the rear shell 12 and the middle shell 11 can be achieved, ensuring the correct position of the rear shell 12 and the middle shell 11 during the assembly process and simplifying the assembly process. The design of the limiting rib 122 and the limiting groove 111 can also increase the connection strength between the rear shell 12 and the middle shell 11, improve the overall structural stability of the product, and reduce problems caused by looseness. The second avoidance notch 44 corresponding to the limiting rib 122 can ensure the convenient installation of the carrier sheet 4.

[0040] In an optional embodiment, a first rib 123 is provided on the inner wall surface along the edge at one end of the rear shell 12 close to the front shell 13, and a third avoidance notch 45 is provided on the carrier sheet 4 at one end corresponding to the first rib 123 close to the front shell 13. The second avoidance notch 44 can ensure the convenient installation of the carrier sheet 4.
