Abstract
PURPOSE:To obtain a piezoelectric sounding body which has small higher harmonic distortion by supporting the peripheral part of the sounding body by two rubber O rings from above and below. CONSTITUTION:A diaphragm is formed by sticking piezoelectric materials 12 which electrodes 11 formed on both surfaces on a circular metallic plate 13 and its peripheral part is supported by sandwiching the peripheral part between rubber O rings 14 whose diameter is equal to that of the support part and fixing the rubber O rings 14 to a fixing body 15. At the contact between the fixed rubber O rings 14 and diaphragm, the diaphragm is not fixed completely and supported nearly in a free state because the rubber O rings 14 provide easiness to move in a torsional direction. The diaphragm is therefore displaced efficiently under the same driving conditions and a sounding body having high sound pressure level is obtained. Consequently, unnecessary vibrations in modes other than a main mode hardly occur and a sound with small distortion can be generated.
