Abstract

PURPOSE:To increase the output of low frequencies of reproducing sound and to improve the frequency characteristics, by taking the width of an oscillation tip if a piezoelectric oscillator broader than that at the fixed side. CONSTITUTION:A piezoelectric plate 13 is provided at the center of a ping-pong racket-shaped metallic plate 12, the narrower side of the plate 12 is inserted to a speaker case fixed part 14 and fixed, and the wider side of the plate 12 is taken as the oscillation tip. To the oscillation tip of a piezoelectric oscillator 11, the center point of a diaphragm 15 fixing the circumference to a speaker case support 17 via a foamed urethane support 16 is coupled. In this case, the size ratio of a width (d) of the oscillation tip divided by an effective length (l) is selected in the range of 0.75-2. Thus, the acoustic output of the entire sound width can be increased practically.
