Piezo Schwingkreis Extern

Das Piezoprinzip beruht, einfach ausgedrückt, auf die gerichtete Verformung eines piezoelektrischen Materials. Dafür wird meistens eine Messingscheibe mit einer vom Durchmesser kleineren Keramikscheibe auf einer Seite fest verklebt.
Beim Anlegen einer Wechselspannung verformt sich nun die Scheibe und wölbt sich in eine Richtung und wieder zurück. Dieser Wechsel folgt entsprechend der Frequenz der Wechselspannung und erzeugt somit einen Ton. Da der Frequenzbereich eher sehr eng gefasst ist, werden Piezo Signalgeber vorzugsweise für die Wiedergabe einer Frequenz mit hohem Schalldruck verwendet. Für eine Verwendung als Sprach- oder Musikwiedergabe ist die Piezoscheibe daher weniger geeignet. Ist die Piezoscheibe in einem Gehäuse verbaut wir dieses System häufig als Piezo Transducer bezeichnet.
