Piezo signal generator with feedback loop electrode
The great advantage of this resonant circuit is that the piezo disk is operated at its resonant frequency and the highest possible volume is generated.
When a DC voltage is applied, the metal disk deforms. In this case, an additional voltage is generated in the feedback electrode, which in turn controls the resonant circuit and adjusts to the resonant frequency.
