Abstract
A unitarily molded seal membrane (310) includes an integral microphone support (304) which includes a diaphragm (306). A cavity wall (406) is located about said diaphragm (306) on one side of the seal membrane (310). The cavity wall (406) defines a cavity area (410) for receiving a microphone (504). The cavity wall aligns the diaphragm (306) in front of the microphone (504), thereby allowing for environmental sealing of the microphone (504).
