ABSTRACT:
A crystal sound producer has a piezoelectric crystal plate diaphragm which produces sound waves when applied with a voltage thereacross. A waveform transform plate has slits or linear grooves through which the sound waves from the diaphragm are radiated in semicylindrical waves. As these semicylindrical waves propagate in the air, they superpose one another to form generally plane waves which sound natural to the human hearing. The crystal sound producer can be used in portable articles such as badges.
