    Abstract: Aspects of the subject technology relate to liquid-resistant microphone modules for electronic devices. A microphone module may include a non-porous membrane that seals the front volume of the microphone module from the external environment of the electronic device. The microphone module may also include a substrate having an opening that allows airflow between the front volume and an interior cavity within the housing of the electronic device. In various implementations, an inductive vent and/or a resistive vent may be provided over the opening in the substrate.

    Abstract: Aspects of the subject technology relate to low noise microphone assemblies for electronic devices. A microphone assembly may include components for sensing sound, mounted on a substrate, under a cover disposed on the substrate. The components may receive sound through an opening in the substrate. The microphone assembly may include an interposer on the substrate. The interposer includes one or more contacts on a surface that is spatially separated from the surface of the substrate, in a direction perpendicular to the surface of the substrate. A first side of the substrate may be mounted to an inner surface of a housing of the electronic device. The components, the cover, and the interposer may be mounted to an opposing second side of the substrate. A flexible printed circuit may be coupled to the contacts on the surface of the interposer, and mechanically attached to a surface of the cover.

    Abstract: A liquid-resistant microphone assembly includes a substrate defining a sound-entry region and a microphone transducer coupled with the substrate. The transducer has a sound-responsive region acoustically coupled with the sound-entry opening defined by the substrate. A liquid-resistant port membrane spans across the sound-entry opening defined by the substrate. The membrane is gas-permeable. An adhesive layer is positioned between the substrate and the liquid-resistant port membrane, coupling the liquid-resistant port membrane with the substrate and spacing the liquid-resistant port membrane from the substrate to form a gap between the membrane and the substrate. The adhesive layer defines an aperture having a periphery extending around and positioned outward of the sound-entry region. Modules and electronic devices incorporating such a microphone transducer also are disclosed.
