ABSTRACT:
Nodal contacts for piezoelectric audio transducer comprise an annular surface in a conductive housing member which is attached resiliently to a circuit board. The transducer is clamped resiliently between the annular surface and first and second contacts mounted to the board. The first contact is situated on a semicircular wall which forms a resonant cavity and the second contact is situated on a post in an aperture defined by the wall. An alternative embodiment utilizes a plastic housing member with slots in the top thereof which allow resilience of the annular surface.
