Piezo Signalgeber mit Rückkopplungselektrode
Der große Vorteil bei diesem Schwingkreis, dass die Piezoscheibe mit ihrer Resonanzfrequenz betrieben wird und dabei die größtmögliche Lautstärke erzeugt wird.
Beim Anlegen eine Gleichspannung verformt sich die Metallscheibe. Dabei wird zusätzlich eine Spannung in der Rückkopplungselektrode erzeugt, die wiederum den Schwingkreis steuert und auf die Resonanzfrequenz einschwingt.
