Make sure that you are driving the piezo at the frequency that the
datasheet specifies. Piezo buzzers are resonant in a specific frequency
range. If you are outside of that range, they will under perform.

Hiya everyone!
Does anyone have any simple schematic or any ideas how to amplify the
sound of a 2 pin piezo?
For now I drive it simply from a controller pin, but the sound is
somewhat quiet for an alarm clock, so I'm looking for something different.
Thanks! :)
