Abstract:
An audio capture device for a submersible camera including a supporting structure to prevent a waterproof membrane from deflecting beyond a point that will cause damage to the membrane. A microphone assembly includes a microphone for detecting ambient sound and generating an electrical signal representing the ambient sound. The microphone assembly is covered by a waterproof membrane to prevent water from reaching the microphone assembly. One or more supporting rings near the waterproof membrane prevents the waterproof membrane from deflecting more than a threshold deflection.
