1.When is using the piezoelectric ceramic sheet to make a buzzer, why the wire can't be soldered on the piezoelectric ceramic sheet? In addition, capacitance of the piezoelectric ceramic sheet is the same as the ceramic capacitor?
The piezoelectric ceramic is used to make the buzzer. If this problem occurs, it is caused by the mismatching between the welding material, the solder wire for the specific reason.Calculating the capacitance of the piezoelectric ceramic is the same as the piezo ceramic capacitor, and the formula of the piezo plates and blocks capacitor is used.
2.About piezoelectric ceramic , if you want to vibrate, then what are the simple methods? In addition, how much voltage can it generate if it is mechanically vibrated?
If you want the piezoelectric ceramic to vibrate, then the simple method is to connect it to the secondary AC voltage of the small transformer. About mechanical vibration of the piezoelectric ceramic , the range of its voltage rises and falls, it is 0.1-0.15V, which is very small.
