Abstract
In one exemplary embodiment, an apparatus includes: a first substrate having an aperture adapted to receive an acoustic signal; a microphone comprising a plate connected to the first substrate and a movable member connected to the first substrate, where the microphone is adapted to transduce the received acoustic signal into an electrical signal; a second substrate connected to the first substrate; at least one wall connected to the first substrate and the second substrate such that the at least one wall, the first substrate, the second substrate and the microphone define an interior cavity; and an electrical component on the second substrate and electrically coupled to the microphone, where the electrical component is configured to generate an output based on the electrical signal.
