Abstract: The problem of contaminants entering a microphone assembly through a pressure equalization aperture is mitigated by moving the pressure equalization aperture from a location near the acoustic port to a location on the cover of the microphone assembly. This is achieved by fabricating an aperture reduction structure using a separate dedicated die, with an aperture of diameter ˜25 microns or less disposed on the aperture reduction structure, and then coupling the aperture reduction structure to the cover of the microphone. The relatively smaller aperture on the cover after the coupling of the aperture reduction structure is used for pressure equalization of the back volume of the microphone with a pressure outside of the microphone assembly.
