In one embodiment of the present invention, a digital microphone fixing structure of an electronic device mainly includes a main board 1, an elastic circuit board 2, a microphone unit 3 and a contact spring mechanism 5.
Wherein, the upper surface of one end of the elastic circuit board 2 is provided with a microphone unit 3 for receiving external sound waves. In general, the microphone unit 3 may be soldered to the elastic circuit board 2, and a microphone chip or other structure is provided in the microphone unit 3, so as to be in signal connection with the elastic circuit board 2. The other end of the elastic circuit board 2 is electrically connected with the main board 1, and each contact spring piece mechanism 5 is arranged on the main board 1 and is positioned between the main board 1 and the other end of the elastic circuit board 2. The upper end and the lower end of each contact spring plate mechanism 5 are respectively abutted against the other ends of the main board 1 and the elastic circuit board 2, and under the action of the pressing force of the two, the other ends of the main board 1 and the elastic circuit board 2 are kept in tight physical connection through the contact spring plate mechanisms 5, so that stable point connection is ensured.
Thus, the digital microphone fixed mounting structure provided by the embodiment ensures stable signal transmission between the elastic circuit board 2 and the main board 1 through the physical butt between the elastic circuit board 2 and the main board 1 by the contact type spring plate mechanism 5, so that the receiving signal of the microphone 3 can be transmitted to the main board 1 through the elastic circuit board 2 and the contact type spring plate mechanism 5 in sequence, stable signal connection between the microphone and the main board 1 is realized, and normal operation of the microphone is ensured.
Furthermore, the flexible flat cable 6 can be used for realizing signal connection between one end of the elastic circuit board 2 and the other end of the elastic circuit board 2, so that the relative position relationship between one end of the elastic circuit board 2 and the other end of the elastic circuit board can be conveniently adjusted, and the flexible flat cable is more suitable for electronic equipment with complex installation space and narrow installation environment. Of course, signal connection CAN be realized between two ends of the elastic circuit board 2 through a cable, a data plug, wireless communication and other modes, such as a USB interface, a CAN bus, a WIFI module and the like.
In addition, considering that the microphone unit 3 is disposed on the upper surface of one end of the elastic circuit board 2, the load of the elastic circuit board 2 is relatively large, and for this reason, the adhesive layer 7 is disposed on the bottom surface of the elastic circuit board 2, and the connection stability between the two can be effectively improved by the surface connection between the adhesive layer 7 and the main board 1.

The supporting frame 903 is generally used for installing the other end of the elastic circuit board 2, and after the one end of the elastic circuit board 2 is installed in place, the supporting frame 903 can further compress the elastic circuit board 2, so that the other end of the elastic circuit board 2 maintains a pretightening force on the contact spring mechanism 5. In order to facilitate positioning and mounting of the other end of the elastic circuit board 2 in the top shell 9, in this embodiment, a plurality of positioning holes 202 are preset on the edge of the other end of the elastic circuit board 2, and meanwhile, positioning columns 904 with the same number and distribution are additionally arranged on the supporting frame 903, so that positioning and mounting of the elastic circuit board 2 can be conveniently realized through cooperation of each positioning column 904 and the positioning hole 202, and meanwhile, connection stability is ensured.
