Abstract: A cover for protecting an audio port of an electronic device is provided. The cover includes a check valve, a bellows, and an air vent. The check valve moves between a first position to allow audio pressure to exit the audio port and a second position to fluidly seal the audio port. The bellows at least partially surround the audio port when the cover is attached to the electronic device and move the check valve from the first position to the second position in response to a pressure exerted on the bellows. The air vent is attached to the bellows and allows audio pressure to pass through the air vent and to restrict passage of at least some water through the air vent.

Abstract: A protective case for an electronic device having a touch screen and an audio port. The protective case includes a front portion including a rigid frame extending around a perimeter and a screen aperture configured to provide access to the touch screen of the installed electronic device. The protective case includes a back portion removably attached to the front portion and includes a sealing member configured to directly contact a portion of the electronic device. The sealing member has an aperture defining a circumference configured to encircle the audio port of the installed electronic device and form a water-proof seal between the installed electronic device and the sealing member of the protective case. The protective case includes a vent mesh covering the aperture of the sealing member and configured to allow air to pass through the vent mesh and to resist the flow of water through the vent mesh.
