Embodiment
In order to solve the problems, such as the sealing structure of the prior art since the influence of manufacturing tolerance causes sealing reliability poor, this
Invention provides a kind of microphone sealing device, and below in conjunction with attached drawing and embodiment, the present invention is carried out further specifically
It is bright.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, the present invention is not limited.
The structural decomposition diagram and profile of a kind of microphone sealing device of the embodiment of the present invention are respectively such as Fig. 3 and figure
Shown in 4, which includes sealing shroud, elastomer, compressed part and location division；Microphone 8 is welded on mainboard 7, the sealing shroud
It is sleeved on the microphone 8, the elastomer is connected between the sealing shroud and compressed part, and it is described fixed that the compressed part passes through
Position portion is installed on the mainboard 7.
The compressed part includes shaft 2 and clamp spring 4.The shaft 2 is fixedly connected with the sealing shroud, its connection mode can
Be combined as a whole part in a manner of by in-mould injection, and the mode that can also adopt the fixation that is screwed or is buckled is incorporated in one
Rise.Annular groove is provided with the shaft 2, the clamp spring 4 can be stuck in the annular groove, and the annular groove can be one
Can also be multiple, in the present embodiment, 5 annular grooves 21,22,23,24,25 are equidistantly positioned in the shaft 2.The present invention
Middle clamp spring 4 can be connected in different annular grooves, can be realized to the elastic force of the elastomer by this snap fit
