Piezo Circuits Click Sound Generator
January 10, 2009
Often in computer controlled systems, you would like to generate a “click” sound
whenever a button is pressed. This provides the user with audible feedback that
the pushbutton press has been acknowledged. The two circuits below generate such
a sound. A click sound is generated each time the logic input swings from a
logic low to high condition.
