About the three-pin boost inductance of the Piezo buzzer Diaphragm
The driving circuit of the piezoelectric ceramic buzzer is only 3V because it uses a button battery, and a three-pin boost inductor is used. The driving waveform is a 5.1Kz square wave
The questions as below: 1. What principles should the boost inductor work follow to design? Is it according to resonance?
2. The parameters currently selected for the boost inductor. The driving current is fast 30mA during operation, and the button battery can not stand it. Is there any basis for parameter design? The number ratio of front and rear? Inductance ratio? Secondary inductance value?
If you want to get the answer, please contact the engineers of FBelec
