This design can ensure that the connection between the noise reduction microphone 6 and the flexible circuit board 8 is stable and reliable, and functional problems caused by poor connection can be avoided. By fixing the flexible circuit board 8 in position using the mounting posts 57, the assembly process can be made simpler and more efficient. The mounting posts 57 help ensure the correct position of the circuit board, and also help with subsequent maintenance and repair.

[0043] The flexible circuit board 8, also known as a flexible printed circuit board (FPC), is a soft circuit board composed of a flexible substrate (usually a polyester film or a polyamide film) and a conductive circuit. The flexible circuit board 8 can be bent, folded and curved, and can better adapt to complex internal structures and space constraints, thereby achieving a more flexible and compact layout. Specifically, a main control circuit board 8 is also provided in the headset, and the noise reduction microphone 6 is electrically connected to the main control circuit board 8 through the flexible circuit board 8, thereby realizing the collection, transmission and processing of sound signals. In addition, the battery 3 and the speaker 4 are also electrically connected to the main control circuit board 8 directly or indirectly to realize the normal operation of the battery 3 and the speaker 4.

[0044] like Figure 4 , Figures 6 to 8 As shown, a guide support block 54 is provided at the edge of the speaker bracket 5, and the flexible circuit board 8 is guided to the side of the speaker bracket 5 away from the sound outlet 12 through the guide support block 54, and the edge of the speaker 4 is supported on the guide support block 54. The guide support block 54 helps to guide the flexible circuit board 8 to the correct position, ensuring that the circuit board is correctly connected to the speaker bracket 5 and is located in the appropriate position. The edge of the speaker 4 supported on the guide support block 54 can provide additional support and stability to prevent the speaker 4 from loosening or being damaged due to vibration or movement during use. By supporting the edge of the speaker 4 on the guide support block 54, it can be ensured that the connection between the speaker 4 and the flexible circuit board 8 is stable and reliable, avoiding performance problems caused by improper connection.

[0045] Furthermore, a guide groove 55 extending from the edge to the mounting column 57 is provided on the side of the speaker bracket 5 facing the speaker 4. The flexible circuit board 8 is guided to the noise reduction microphone 6 through the guide groove 55 and is electrically connected to the noise reduction microphone 6. The provision of the guide groove 55 can help accurately position the flexible circuit board 8, ensure that it is connected to the noise reduction microphone 6 at a specific position, and help improve the accuracy and stability of the connection.
