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.
Claims15
A camera comprising:
- a camera body comprising a loudspeaker grille;
- a loudspeaker housing comprising a wall fixedly attached to an internal portion of the camera body, wherein a portion of the wall protrudes into an internal area of the loudspeaker housing to form a lip portion, wherein the lip portion comprises a first surface that is facing externally away from the loudspeaker housing and a second surface that is facing internally towards the loudspeaker housing;
- a loudspeaker assembly fixedly attached to the loudspeaker housing, the loudspeaker assembly comprising:
- a loudspeaker;
- and
- an audio circuit board fixedly attached to the loudspeaker;
- a waterproof membrane attached to the first surface of the lip portion of the loudspeaker housing and separating the loudspeaker assembly from the loudspeaker grille;
- a support structure attached to the second surface of the lip portion of the loudspeaker housing and separating the waterproof membrane from the loudspeaker assembly, the support structure configured to limit an amount of deformation of the waterproof membrane, the support structure fixedly attached to the loudspeaker assembly and the second surface of the lip portion of the loudspeaker housing and comprising an array of support structure ports configured to allow passage of sound waves from the loudspeaker to the waterproof membrane;
- the loudspeaker housing configured to mechanically support the loudspeaker assembly, the loudspeaker grille, the waterproof membrane and the support structure such that
- a first loudspeaker cavity exists between a first side of the loudspeaker grille and a first side of the waterproof membrane,
- a second loudspeaker cavity exists between a second side of the waterproof membrane and a first side of the support structure, and
- a third loudspeaker cavity exists between a second side of the support structure and a first side of the loudspeaker assembly.
A camera comprising:
- a camera body comprising a loudspeaker grille;
- a loudspeaker housing comprising a wall fixedly attached to an internal portion of the camera body, wherein a portion of the wall protrudes into an internal area of the loudspeaker housing to form a lip portion, wherein the lip portion comprises a first surface that is facing externally away from the loudspeaker housing and a second surface that is facing internally towards the loudspeaker housing;
- a loudspeaker assembly fixedly attached to the loudspeaker housing;
- a waterproof membrane attached to the first surface of the lip portion of the loudspeaker housing and separating the loudspeaker assembly from the loudspeaker grille;
- a support structure attached to the second surface of the lip portion of the loudspeaker housing and separating the waterproof membrane from the loudspeaker assembly, the support structure configured to limit an amount of deformation of the waterproof membrane, the support structure fixedly attached to the loudspeaker assembly and the second surface of the lip portion of the loudspeaker housing and comprising an array of support structure ports configured to allow passage of sound waves from the loudspeaker to the waterproof membrane;
- and
- the loudspeaker housing configured to mechanically support the loudspeaker assembly, the loudspeaker grille, the waterproof membrane and the support structure.
