发明名称 Vehicular directional microphone assembly for preventing airflow encounter
摘要 A microphone mounting assembly (800A/800b) include one or more transducers (801) mounted to a printed circuit board (PCB) (805) where a spacer (803) is used having a channel (807) positioned on the PCB (805) for allowing acoustical energy to pass through the channel (807) to a port (809) in the PCB (805). A first cover (811) is positioned over the channel (807) for disrupting the direct encounter with airflow into the channel (807) while a top section (813) having a second cover (815) is further positioned adjacent to the first fabric cover (811) for preventing debris from obstructing the first fabric cover (811).
