The microphone unit can be easily assembled onto the device via the connector and electrical connection post, while also shortening the microphone cavity length, reducing the front cavity volume, and improving acoustic performance.

[0025] To describe in detail the structure of the microphone module and electronic device of this utility model, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Figures 1 to 3 The schematic structure of the microphone module according to Embodiment 1 of this utility model is shown from different angles.

[0027] like Figures 1 to 3 As shown in the figure, the microphone module of Embodiment 1 of this utility model includes a microphone unit 1, a connector 2, and an electrical connection post 3 disposed on the connector 2. The microphone unit 1 is fixed on the connector 2 and is electrically connected to the connector 2. The electrical connection post 3 is positioned and electrically connected to the circuit board of the external device. The microphone unit 1 is then assembled on the device through the connector 2 and the electrical connection post 3. This not only simplifies the application of the microphone unit 1 on the device, but also reduces the overall installation requirements, effectively shortens the length of the microphone cavity, reduces the front cavity volume, and improves acoustic performance.

[0028] In this first embodiment, the connector 2 adopts a shell structure, including a flat electrical connection part 21, a receiving groove 22 disposed on the electrical connection part 21, and a spring piece located in the receiving groove 22; wherein, the microphone unit 1 is limited in the receiving groove 22 and elastically contacts and conducts with the spring piece, the electrical connection post 3 is distributed on the electrical connection part 21, and the microphone unit 1 conducts with the electrical connection post 3 through the spring piece, and then connects to the external whole machine through the electrical connection post 3.

[0029] Specifically, to ensure the stability of the microphone unit 1, at least two latches 23 can be set at the opening of the receiving slot 22. The microphone unit 1 is elastically fastened in the receiving slot 22 through the cooperation of the latches 23 and the spring piece. In the application process, the microphone module formed by the microphone unit 1 and the connector 2 is a whole structure. The microphone can be assembled by connecting and positioning it with the whole machine through the electrical connection post 3, thereby effectively reducing the assembly operation and improving the assembly efficiency.

[0030] In addition, for microphone units 1 of different types or sizes, corresponding receiving slots 22 structures can be set, and the springs located in the receiving slots 22 can be distributed on the bottom and / or side walls of the receiving slots 22. The specific position and size of the springs can be set according to the distribution of the solder pads of the microphone unit 1. After the microphone unit 1 is limited in the receiving slots 22, the contact and conduction between the springs and the solder pads of the microphone unit 1 can be completed.

[0031] To ensure the microphone functions, a first through hole 24 corresponding to the sound hole position of the microphone unit 1 can be provided on the receiving groove 22. The position of the first through hole 24 can be located on the bottom plate or side wall of the receiving groove 22, depending on the position of the microphone in the receiving groove 22, and is not limited to the specific structure shown in the figure.

[0032] It should be noted that in this first embodiment, the connector 2 is a shell-like structure, so the electrical connection posts 3 can be set on the electrical connection part 21 and distributed around or at least on one side of the microphone unit 1. During the assembly process, the electrical connection posts 3 can be directly inserted into the corresponding electrical connection holes of the whole machine to complete the assembly positioning and electrical connection operation. The setting position and number of electrical connection posts 3 can be flexibly set according to the installation requirements of the whole machine, and are not limited to the specific structure shown in the figure of setting one electrical connection post 3 on the left side of the microphone unit 1 and setting two electrical connection posts 3 on the right side of the microphone unit 1.

[0033] Figures 4 to 6 The schematic structure of the microphone module according to the second embodiment of the present invention is shown from different angles.

[0034] like Figures 4 to 6 As shown in the figure, the microphone module of Embodiment 2 of this utility model includes a microphone unit 1, a connector, and an electrical connection post 6 disposed on the connector; wherein, the microphone unit 1 is fixed on the connector and is connected to the connector, and the electrical connection post 6 is positioned and connected to the circuit board of the external whole machine, thereby realizing the assembly of the microphone unit 1 on the whole machine through the connector and the electrical connection post 6.

[0037] It should be noted that in both embodiments described above, a socket structure can be provided at a preset installation location on the entire device, such as on the circuit board. During the assembly of the microphone module, the electrical connection post 6 can be directly inserted into the corresponding socket to achieve connection and conductivity between the microphone unit 1 and the entire device. Furthermore, when the number of socket positions allowed on the entire device is insufficient for effective positioning of the microphone module, non-conductive positioning posts can be provided on the connector, and corresponding positioning holes can be provided inside the entire device (such as on the circuit board or housing). With the assistance of the positioning posts and holes, and in conjunction with the electrical connection post, effective assembly with the entire device can be achieved.
