ABSTRACT:
A disc of piezoelectric ceramic with a plurality of parallel slots cut into a top surface. Another plurality of slots is cut into the bottom surface of the disc with the parallel slots on the top being perpendicular to the parallel slots on the bottom. For one application a shallow keyway slot is cut into the top and/or bottom surface, traversing the already cut slots, to serve as a receptacle for an electrode ribbon.
