Hi,
What's a good amplifier for Piezo buzzer.
I want to have 50Vp-p on the buzzer so it's very luad.
Please help.
yes it can.
When you say amplifier, what voltage level of piezo drive signal do have at present.?
I have 20Vp-p on Piezo now. But it's not as luad as I need. What can I do to have it
lauder
I think I'm not using the right buzzer in the operating frequency. I have to change the buzzer and then I don't think as big as 20V amplification is required. 10V may be ok. what do you think?
hi,
What sound intensity do you want in dB at what frequency.????
What will be the piezo sounder driving circuit.??
I need 85 dB at 400Hz to 1100Hz.
I'm using a trasnistor to drive it.
what's sound pressure?Sound pressure must be stated at a certain distance.
Why must the driver be a push-pull?A single transistor can't drive a piezo transducer. The driver must be push-pull.
What happens if we have a resistor in parallel? Can' it discharge the capacitor of the Buzzer?I piezo transducer is a capacitor that has no resistance so a single transistor can pull it only in one direction but not drive it with AC.
