摘要： The disclosed technology provides solutions for preventing the ingress of potentially harmful materials, such as moisture and debris, into a sensor housing. In some aspects, an ingress-protection sub-assembly is provided. The sub-assembly can include a t-protector mounted to an outer surface of a face-plate, wherein the t-protector is disposed above an inlet in the face-plate, a printed circuit board (PCB) mounted to an inner surface of the face-plate, and a membrane disposed between the PCB and the face-plate. Methods for assembling and mounting a sub-assembly are also provided.

摘要： Aspects of the present disclosure relate to sealing and protecting micro-electromechanical systems (MEMS) microphones. In some cases, a MEMS microphone protection apparatus may include a housing, at least one acoustic port extending through the housing providing an aperture; and at least one membrane positioned within the at least one acoustic port. In some examples, the membrane can seal the at least one acoustic port.
