EMBEDDED DIELECTRIC AS A BARRIER IN AN ACOUSTIC DEVICE AND METHOD OF MANUFACTURE
First Claim
1. A microphone base, the base comprising:
- a plurality of metal layers;
a plurality of core layers, each of the plurality of core layers being disposed between selected ones of the metal layers;
a dielectric membrane disposed between other selected ones of the plurality of metal layers;
a port that extends through the metal layers and the core layers but not through the dielectric membrane;
such that the dielectric membrane has a compressed portion and an uncompressed portion, the uncompressed portion extending across the port and the compressed portion being in contact with the other selected ones of the metal layers;
such that the compressed portion of the membrane is effective to operate as a passive electronic component and the uncompressed portion is effective to act as a barrier to prevent at least some external debris from traversing through the port.

Abstract
A microphone base includes a plurality of metal layers and a plurality of core layers. Each of the plurality of core layers is disposed between selected ones of the metal layers. A dielectric membrane is disposed between other selected ones of the plurality of metal layers. A port extends through the metal layers and the core layers but not through the dielectric membrane. The dielectric membrane has a compressed portion and an uncompressed portion. The uncompressed portion extends across the port and the compressed portion is in contact with the other selected ones of the metal layers. The compressed portion of the membrane is effective to operate as a passive electronic component and the uncompressed portion is effective to act as a barrier to prevent at least some external debris from traversing through the port.
