TRANSDUCER SUPPORTING AND CONTACTING MEANS

摘要

: Supporting and contacting means for piezoelectric audio transducer comprises a cylindrical housing with an annular surface therein which bears resiliently against a first surface of the transducer to hold it against contacts which bear against the second surface. Three uniformly spaced ribs on the inside surface of the housing serve to center the transducer therein so the annular surface will bear only on the resonant node of the vibration. The housing may be conductive so that the annular surface acts as an electrical contact. In one embodiment the annular surface is resiliently attached to the housing.
