[0048] ​As the background art, the related art microphone device has the problem that the board assembly cannot be stably retained in the shell, and the inventor has found that the cause of this problem is that the board is fixedly arranged on the profile bracket, and the profile bracket provided with the board is arranged in the shell of the microphone. However, this mounting method causes the microphone device to have many assembly parts, and it is not convenient to fixedly arrange the mounting bracket provided with the board in the shell, which will inevitably cause the problem of unstable connection structure between the profile and the shell.

[0049] In addition, the terminal portion of the board assembly is connected with the connecting wire, and when the terminal portion is affected by the pulling force of the connecting wire, the connection position between the terminal portion and the board may be deformed or broken, thereby reducing the service life of the board assembly.

[0050] To solve the above technical problems, the embodiment of the present application provides a microphone device, which is provided with an integrally formed mounting bracket in the shell, and a limiting bracket is arranged on the outer circumferential surface of the shell. During the assembly of the microphone, the worker only needs to insert the board assembly into the mounting bracket of the shell, and the terminal portion of the board assembly is limited by the limiting bracket to achieve the positioning effect of the board assembly in the shell, thereby avoiding the need for a separate profile bracket for mounting the board assembly in the related art. By using the integrally formed structure of the shell and the mounting bracket, the connection stability between the mounting bracket and the shell is improved, and the board assembly arranged in the mounting bracket is kept in a stable mounting state.

[0051] Further, the terminal portion of the board assembly is located in the limiting hole of the limiting bracket, so that the limiting bracket supports the terminal portion, effectively avoiding the horizontal support effect of the limiting bracket on the terminal portion when the terminal portion is connected with the connecting wire, thereby avoiding the deformation or breakage between the terminal portion and the board caused by the pulling of the connecting wire.

[0052] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.
