Abstract
PURPOSE:To secure the sufficient output of the melody tone requiring the wide frequency band by installing two units of sound generators which have the resonance points at the high and low positions of the frequency band. CONSTITUTION:Piezoelectric element 4 is sealed to vibrating plate 3 to form piezoelectric sound generator A, which has the resonance point in the low frequency band and is suited to deliver the low-pitched sound part in terms of music, i.e., the signals like the background music. At the same time, piezoelectric element 7 is adhered also to match frame 6 printed on windbreak glass 5 to form piezoelectric sound generator B featuring the resonance point in the high frequency band. Thus the melody is produced from these generators A and B.
