Hi folks,
I was driving a piezo transducer with 6V(peak-peak), 2 kHz using a function generator. I saw on the oscilloscope that the waveform did
not looked like a square wave. I know that a piezo transducer is like a capacitor. I thought that the distorted waveform was
due to fast charging and discharging of the piezo transducer. So I tried to put a 1k resistor in parallel with the piezo and the waveform did not changed (still distorted). I tried decreasing and increasing the value of voltage and parallel resistor but the waveform did not changed .
In my knowledge, the sound is louder when the piezo waveform is close to square wave. what are the ways to make the piezo waveform close to square wave so it will have louder sound? Attached is the piezo waveform I captured.
Thanks
