Abstract:
A microphone includes a microphone base that has a first surface and a second surface. The microphone also includes a microelectromechanical system (MEMS) device coupled to the first surface of the microphone base. The microphone also includes a cover coupled to the first surface of the microphone base, such that the cover divides the first surface into a covered portion where the cover encloses the MEMS device, and a non-covered portion extending away from the cover. The microphone also includes one or more pads on the uncovered portion of the first surface of the base. The microphone also includes a port extending through the base from the first surface to the second surface.
