CMOS Piezo Transducer Buzzer Driver Circuit
A CMOS gate and transistor buffer can be used as an effective driver for a piezoelectric or piezoceramic transducer.
|ICa And ICb||CD4011|
|S1||Single Pole Double Throw Switch|
This CMOS oscillator circuit for driving piezo-electric elecments.
S1 switch configurations
1 = ENABLE
2 = INHIBIT
You can change piezoelectric transducer sound changing R2 and C1 values.
PIN A connected to +5V and PIN B connected to Q1 collector.
