Abstract: An electronic device having an interior volume, the electronic device including a sealing mechanism to prevent ingress of water into the interior cavity. The sealing mechanism having a channel having a first opening at an external environment and a second opening that leads to the interior volume, a membrane that covers the second opening, the membrane being air permeable and water resistant such that the membrane allows air to pass and prevents passage of water up to an upper pressure threshold, a stopper mechanism, and a diaphragm comprising a surface arranged to receive an external water pressure and that is air and water impermeable, the diaphragm being coupled to the stopper mechanism that deflects in response to the water pressure such that the diaphragm actuates the stopper mechanism and seals off the channel from at the first opening preventing water pressure at the membrane from exceeding the upper pressure threshold.
