Claim 28:
29. An electronic device, comprising:
a housing defining an internal volume;
a microphone module disposed within the internal volume, the microphone module comprising:
a substrate;
a cover mounted to the substrate, wherein the cover separates a back volume of the microphone module from the internal volume,
a front volume that is separated from the back volume by a sound-responsive element and that is fluidly coupled to a first opening in the substrate;
a non-porous membrane that defines a sealed volume that is fluidly coupled to the front volume via the first opening, and that provides a liquid-resistant seal between the front volume and an environment external to the housing; and
a second opening in the substrate that extends from the sealed volume defined by the non-porous membrane, through the substrate, to the internal volume of the housing external to the cover.
