Abstract

PURPOSE:To improve the output of the low sound band to make the output characteristic flat, by making the width of the metallic plate of the vibration tip part wider than that of a fixed metallic plate and setting the value of the dimension ratio to the effective length of the vibration to a 2-3 range. CONSTITUTION:A piezoelectric plate 13 is combined with the center of a metallic plate 12 having a racket form of the table tennis by adhesion or the like, and the narrower side of the metallic plate 12 is inserted to a fixed part 14 of speaker case and is fixed, and the wider side of the metallic plate is used as the vibration tip part. The value of a dimension ratio d/l obtained by dividing a width (d) of the vibration tip part by an effective length l is limited in a 2-3 range. By this constitution, the output characteristic is made flatter to enhance the output throughout a wide band.
