Dynamic diaphragm component is directly secured together, and forms sub-assembly 150 so that vibrating diaphragm component and the assembling side of second shell 120
Formula is simpler, can be accurately positioned, and vibrating diaphragm component need not be deep into case inside as traditional assembly method
Wall is positioned using the boss being arranged on case inside wall.In addition using machine spraying hot-melt adhesive technique, hand is not used
Work coats epoxy glue, improves work efficiency, and controls the diaphragm vibration plate 140 to arrive by adjusting the thickness of membrane support frame 130
The distance of second shell 120, simpler so as to adjust the ratio of diaphragm both sides cavity, positional precision higher.Go out acoustic aperture 170
It is arranged in second shell 120, can spatially accommodate entire connecting hole 160, when can make assembling, observe that conducting piece is
It is no to be inserted into connecting hole 160, play the role of detection to the accurate positionin of assembling.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that come for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
