Terminal assembly structure of MEMS microphone
The present disclosure provides a terminal assembly structure of a MEMS microphone, including a signal let out board disposed at a terminal and a silicon microphone disposed on the signal let out board. The silicon microphone includes a housing, a substrate forming an accommodation space with the housing, an MEMS chip and a waterproof member. The substrate is configured with a sound inlet connected to the outside. The waterproof member is sandwiched between the MEMS chip and the substrate. A position where the signal let out board corresponds to the silicon microphone is configured with an accommodation hole. The housing is accommodated in the accommodation hole. The substrate abuts a surface of the signal let out board and covers the accommodation hole. A surface of the substrate where the housing is assembled, is provided with at least one pad electrically connected with the signal let out board.
