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.
