Abstract:
1. A protective cover for an electronic device, the protective cover comprising: a case for at least partially enclosing the electronic device, the case having a rigid frame with an inner surface, an outer surface, and a cavity in the rigid frame positioned proximate at least one sound aperture in the rigid frame, the sound aperture being proximate an acoustic opening of the electronic device when the electronic device is installed in the case; and a sound transmission apparatus disposed at least partially in the cavity of the rigid frame, the sound transmission apparatus comprising an acoustic isolation mechanism having an interior face oriented towards the interior of the case and an exterior face that contacts the inner surface of the case, at least one acoustic channel extending from the interior face to the exterior face of the acoustic isolation mechanism, the acoustic channel acoustically coupling the acoustic opening of the electronic device with the sound aperture, at least one acoustic membrane that extends from the external face of the acoustic isolation mechanism to an anchor knob, forming a truncated cone structure, wherein the anchor knob of the sound transmission apparatus is coupled to the inner surface of the case.
