Abstract
A Micro-Electro-Mechanical System (MEMS) microphone can include a housing, an integrated circuit (IC), and a MEMS transducer. The housing can include a cover mounted on a base having a first printed circuit board (PCB) facing a second PCB. A first recess can be located in the base and be at least partially defined by an aperture through the first PCB. A second recess can be located in the base and be at least partially defined by a cavity in the first PCB. An internal electrical interface can be located in the housing on a side of the first PCB facing the second PCB. The MEMS transducer can be electrically connected to the IC and include a diaphragm that separates an interior of the housing into a front volume and a back volume, wherein the first recess and the second recess constitute a portion of the back volume.
