Abstract
A microphone can include a cover having a series of slits and a nest. The nest can be configured to receive a first diaphragm, a second diaphragm, and a PCB in a stacked arrangement, such that the PCB is positioned between the first diaphragm and the second diaphragm. Also, the first diaphragm can define a first plane, the second diaphragm can define a second plane, and the PCB can define a third plane and the first plane, the second plane, and the third plane can extend parallel to one another. The cover can also include slits having a first length and a second length, and the first length can be greater than the second length. The slits can extend both radially and axially.
