More Information
Summary:A piezoelectric sound generating element capable of providing flatter and less fluctuated sound pressure frequency characteristics includes a diaphragm that is formed in a circular plate shape with a circular profile. A piezoelectric element is affixed to the side of a bottom wall portion of the diaphragm. The piezoelectric element has an asymmetric octagonal profile including a pair of long side portions opposing each other, a pair of short side portions opposing each other, and four connecting side portions.
