WIPO Patent Application WO/2019/128436
Kind Code:
A1
Abstract:
The present utility model relates to a sounding device module, comprising a module case and a diaphragm. The module case has an accommodating cavity therein, the diaphragm is fixed in the accommodating cavity, the diaphragm has an upwardly protruding folded ring portion, the protruding folded ring portion faces the inner surface of one side of the module case, and an upwardly recessed groove is provided on the inner surface of the module case facing the folded ring portion. One technical effect of the present utility model lies in that the upper vibration space of the diaphragm can be increased, avoiding the sound quality from being affected by the collision between the diaphragm and the module case caused by insufficient upper vibration space.
