Very Loud Piezoelectric Beeper Electronic Circuit
designed by David Johnson, P.E.

This circuit generates a continuous tone instead of a pulsing one for your hobby project. As seen in the schematic, the hobby circuit delivers about 110db (12 inches away) from a 9v to 12v source using a single inexpensive C-MOS IC. An off-the-shelf piezoelectric beeping device from Panasonic is driven at resonance to insure maximum efficiency.
