Embedded Dielectric As A Barrier In An Acoustic Device And Method Of Manufacture

摘要

A base assembly for an acoustic transducer includes a first substrate with an acoustic port and a dielectric layer having a substantially uniform initial density. One surface of the dielectric layer contacts the first substrate. An opposite surface of the dielectric layer contacts a second substrate having an acoustic port. The respective acoustic ports of the first and second substrates are aligned with each other. The first substrate, the dielectric layer, and the second substrate are laminated together. A substantial portion of the dielectric layer laminated to the first and second substrates has a higher final density due to compaction than does a portion of the dielectric layer disposed in the respective acoustic ports of the first and second substrates.
