Piezoelectric audio transducer
First Claim
1. A three-terminal audio transducer, wherein the outer periphery of a vibrator, which comprises a piezoelectric element placed on a metallic diaphragm, is securely supported on an acoustic casing, and wherein an elastic part is arranged between said casing and a fixing part of said audio transducer so as to be fixed to a mounting body, and wherein said elastic part has sufficient elasticity to enable said vibrator and casing and elastic part to vibrate in a well balanced fashion.

Abstract
A piezoelectric audio transducer adapted to produce a sound output when a vibrator which is formed by bonding a piezoelectric element to a metallic diaphragm is electrified, wherein the audio transducer is formed by securely supporting the outer periphery of the vibrator on an acoustic casing, and a fixing part to be fixed to a mounting body is provided on the audio transducer and is connected to the casing with an elastic body interposed therebetween so as to thereby enable the casing which is fixed to the mounting body to vibrate integrally with the vibrator when said vibrator is vibrated.
