Abstract
A camera system includes an internal loudspeaker assembly for emitting sound waves from the interior of the camera body to the exterior of the camera body through external ports using internal electronic components. Some components of the loudspeaker assembly are sensitive to wet conditions and are protected from the environment by a membrane. The membrane and its support structures are configured to allow the sound waves to translate through the membrane and external to the camera body in both wet and dry environments. The loudspeaker assembly includes a support structure that prevents the membrane from deforming to the point of breaking or to the point of contacting the loudspeaker when submerged.
