Method for fixing microphone shell and circuit board

Abstract

The invention discloses a method for fixing a microphone shell and a circuit board. The method comprises the following steps: firstly, fixing the shell and the circuit board in respective fixing frocks; secondly, connecting the shell onto the circuit board in a butted manner; thirdly, applying a current on the shell and fusing the part of the shell connected with the circuit board, so as to enable the shell to be combined with the circuit board; fourthly, coating sealant in the connecting part of the shell and the circuit board to reinforce the sealed fixing of the shell and the circuit board. According to the method provided by the invention, the shell is fixed on the circuit board, the operation is simple, the edge sealing of a plurality of microphones can be accomplished once, the sealing effect of the microphone after edge sealing is good, the integral edge sealing consistency is better, and the fixing of the shell and the circuit is stable, so as to avoid the phenomenon of deflection or un-tight edge sealing between the shell and the circuit board.

Description

technical field [0001] The invention relates to the technical field of microphones, and more specifically, to a method for fixing a microphone shell and a circuit board. Background technique [0002] With the progress of society and the development of technology, in recent years, as the volume of electronic products such as mobile phones and notebook computers has been continuously reduced, people have higher and higher requirements for the performance of these portable electronic products, which also require matching electronic products. Parts continue to shrink in size, performance and consistency. Under this background, many new products have been released in the field of microphone products, which are one of the important parts of the above-mentioned portable electronic products. [0003] When conventional microphones combine the shell with the circuit board, the shell is usually pressed onto the circuit board by an edge banding machine for edge banding or the shell is ...

Problems solved by technology

[0003] When conventional microphones combine the shell with the circuit board, the shell is usually pressed onto the circuit board by an edge banding machine for edge banding or the shell is directly fixed to the circuit board for edge banding by fixing glue, and the shell is sealed by the edge banding machine. Sealing with the circuit board, this sealing method needs to seal the microphones one by one, which is cumbersome to operate; for the microphone that connects the shell and the circuit board through the fixing glue, because the shell and the circuit board are only connected by the fixing glue Connection, when the connection is fixed and unstable, there is a phenomenon of deflection or loose edge sealing
