Obtain other attached drawings, in which:
Fig. 1 is the schematic perspective view of the utility model vibrating diaphragm；
Fig. 2 is the stereochemical structure decomposing schematic representation of the utility model vibrating diaphragm；
Fig. 3 is the schematic perspective view of the utility model microphone device；
Fig. 4 is the cut-away view of the line A-A along Fig. 3.
[specific embodiment]
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-2, the utility model provides a kind of vibrating diaphragm 100 comprising vibration section 1, by the vibration section 1
The outwardly extending ring portion 2 of periphery, from the ring portion 2 to far from the vibration section 1 direction extend fixed part 3 and
It is attached at the top dome 4 of the vibration section 1.
The top dome 4 includes being sticked to be fixed on the main part 41 of the vibration section 1 and prolonged by the periphery of the main part 41
