ABSTRACT:
A housing for a piezoelectric audio transducer comprises a molded cylindrical body having a transducer-receiving recess. Supporting surfaces are provided in the recess spaced from the inner end surface of the recess for supporting the transducer in spaced relationship to the inner end. Terminal receiving wells are provided in the inner end surface and a contact terminal is mounted in each well. A cantilever spring extends obliquely upwardly from each recess and has a contact portion which bears against a transducer supported on the supporting surfaces. Conductors extend from the terminals to the driving circuit for the transducer.
