Hi,
I am a bit puzzled, I am trying to amplify an audio signal, with a lm386n-1, and I am sure I got the circuit right, as it amplifys loudly through my speaker.
However putting a smaller and more convenient piezo buzzer in place of the speaker, gives me a soft signal, as if there was no amplification.
I put the piezo buzzer directly on the sourcesignal, and the loudness is the same as it is after amplification.
So what is so different in Piezo buzzer as from "normal" loudspeakers, that they seemingly ignore a amplified signal?
Thanks
