Existing microphone then need use manual welding if can not bear the high temperature of reflow soldering etc., and this kind welding manner influence production efficiency, and the increase production cost.And the surface mount microphone can bear the high temperature of reflow soldering etc., but because therefore height of flange influence welding needs the pad height of microphone circuit plate is improved, forms boss, is higher than height of flange.Yet still there are some problems in above-mentioned surface mount microphone, and as boss very difficult control on circuit board technique of wiring board, and cost is still higher; Pad does not have versatility, and different application terminal product needed is redesigned different wiring boards to satisfy its pad requirement.
[utility model content]
The technical problem of the required solution of the utility model is to provide a kind of surface mount microphone, its can solve effectively existing microphone pad at the different application end product can not be general limitation, and solved the wiring board manufacture difficulty that former surface mount microphone need increase pad.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of surface mount microphone is provided, and it comprises a shell, a vibrating membrane, a back pole plate and a printed circuit board (PCB); Described shell is provided with the cavity that can accommodate vibrating membrane, back pole plate and printed circuit board (PCB); Described vibrating membrane is located on the back pole plate, and described printed circuit board (PCB) is connected with back pole plate; Wherein, the superficial layer that described printed substrate extends cavity is provided with a wiring board that is connected with the outside, and described wiring board is provided with and can designs so that microphone has the pad of interchangeability according to the application terminal product.
The wiring board of described surface mount microphone is connected with printed substrate by scolder or other binding agents.
The bottom surface of the shell of described surface mount microphone is provided with balancing slit, circular trough and sound hole, and described vibrating membrane is fixedly arranged on an end of close sound hole in the cavity body, and described back pole plate and vibrating membrane be arranged in parallel; End face away from sound hole on the described shell is provided with opening, and described printed substrate is fixedly arranged on an end of close opening in the cavity.
The back pole plate of described surface mount microphone and the marginal portion between the vibrating membrane have pad to support the formation space.
The cavity that also has been provided with the fixed insulation effect between the printed circuit board (PCB) of described surface mount microphone and the back pole plate has reached the copper ring of electric action.
Compared with prior art, the utility model surface mount microphone covers one deck wiring board again according to the feature of the circuit of application terminal product on printed circuit board (PCB), realize that a microphone is interchangeable to multiple application terminal product, can solve effectively existing microphone pad at the different application end product can not be general limitation, and solved the wiring board manufacture difficulty that former surface mount microphone need increase pad, improved the utilance of microphone product greatly.
