Piezo Lydgiver - 3-12Vac 2,5kHz 75dB, ledning Vognmand DIN-normeret mellemspændingssikringThe piezoelectric ceramic buzzer has a simple structure in which a ceramic piezo element is glued til a vibration plate. The piezoceramic element expands eller shrinks diametrically when an alternating spnding is applied. This characteristic is used til bend the vibration plate, which generates sound. The acoustic generating method can be subdivided roughly into the self drive oscillation method og the external drive oscillation method. The former
