1. A camera comprising:
a housing comprising a port configured to allow passage of sound waves from an external area of the camera to an internal area of the camera;
a circuit board comprising an opening;
a microphone coupled to a first surface of the circuit board adjacent to the opening;
a compressible spacer coupled, by an adhesive, to a second surface of the circuit board that is diametrically opposite to the first surface of the circuit board, wherein the compressible spacer is located entirely on a side of the circuit board adjacent to the second surface, and wherein the compressible spacer is substantially circular with an opening extending through the compressible spacer that is aligned with the microphone; and
a waterproof membrane disposed between the housing and the compressible spacer and covering the opening of the compressible spacer, wherein the waterproof membrane is configured to vibrate so that sound waves extend there through to the microphone.
