Abstract
A camera system with a camera body, a loudspeaker grille, a loudspeaker assembly, a waterproof membrane, and a support structure. The loudspeaker grille allows passage of sound waves from inside to outside the camera body. The loudspeaker assembly has a loudspeaker that converts a signal into the sound waves; and an audio circuit board that processes an audio signal into the signal. The waterproof membrane prevents moisture from passing into the camera body while allowing the sound waves to pass through. The support structure is located between the waterproof membrane and the loudspeaker assembly. A compressible spacer is coupled to the loudspeaker assembly. A loudspeaker adhesive connects the compressible spacer and the loudspeaker. A loudspeaker housing is configured to supporting the loudspeaker assembly, the loudspeaker grille, the waterproof membrane, and the support structure. A first loudspeaker cavity exists between the loudspeaker grille and the waterproof membrane.
