Claim 30:
31. A method of operating a liquid-resistant microphone of an electronic device, the method comprising:
receiving sound from an environment external to the electronic device at a sound-responsive element of the liquid-resistant microphone through a non-porous membrane of the liquid-resistant microphone and through first opening in a substrate of the liquid-resistant microphone; and
generating an electronic signal based on a motion of the sound-responsive element due to the received sound,
wherein the motion of the sound-responsive element due to the received sound causes airflow through a second opening in the substrate between a front volume of the liquid-resistant microphone that is at least partially defined by the non-porous membrane and an interior cavity of the electronic device that is separated from a back volume of the liquid-resistant microphone by a cover mounted to the substrate.
