#190943 - Tweaking after simulation
Responding to: Ralph Sac's previous message
I simulated the original cct
https://photos.go..._PaUkisAv4
https://photos.go...E1Xfz9Idqk and I didn't like the duty cycle of audio o/p waveform
so I modified it to 50% duty cycle for higher volume waveform and frequency that matches resonance of piezo buzzer

Hope this leads to perfection.

Unfortunately insert image does not work anymore in this site!
PS:
OOps! forgot to add piezo buzzer to the simulation to see its effect on o/p Waveform.
Working on it.
