Abstract
A microphone assembly for exterior use on vehicles having a housing base including at least one compartment, a PCBA (printed circuit board assembly) with at least one acoustic membrane, a sealing cover to at least partially overlap with the compartment is disclosed. The sealing cover has at least one opening with said opening at least partially aligned with said acoustic membrane. The assembly has a housing cover including a first grid at least partially aligned with said opening in the sealing cover, and a shielding cover. The shielding cover has a second grid at least partially aligned with said opening in the sealing cover. The first grid and the second grid are aligned in offset in order to provide a labyrinth path without straight passthrough passages from the exterior of the microphone assembly to the acoustic membrane.
