Abstract

A microphone is provided. The microphone has a housing; a back plate positioned within the housing; a die positioned within the housing and coupled to a circuit board having conductive traces; and a conductive layer positioned between the die and the back plate, wherein the conductive layer mitigates coupling of an electrical signal between the conductive traces and the back plate.
