Abstract:
A packaged microphone has a lid structure with an inner surface having a concavity, and a microphone die secured within the concavity. The packaged microphone also has a substrate coupled with the lid structure to form a package having an interior volume containing the microphone die. The substrate is electrically connected with the microphone die. In addition, the packaged microphone also has aperture formed through the package, and a seal proximate to the microphone die. The seal acoustically seals the microphone and the aperture to form a front volume and a back volume within the interior volume. The aperture is in acoustic communication with the front volume.
