I'm trying to push sound through this little peizo buzzer for a talkbox. it's normally coennected to what I assume is a square wave generator but in rearsight, I guess it might be an amp. The circuit has 3 terminals. You put gnd to one and hot to either of the others, depending if you want a solid tone or one with tremolo. I wanna use the peizo cause its beep is ear-peircing plus youtube said to do something similar. When I connected the peizo to my amp alone, it worked but not nearly as loud as the beep. I know it lost its power but... but the amp.

How can I push more sound? power it somehow? maybe put its audio through a terminal while connected the circuit? or is this jewel only good for scaring THE LIVING CRAP out of my neighbors?

Yea so is that an amp too? I noticed it can drive those tiny peizos too. What else can it do that I missed?

The 3 terminals on the piezo are part of an oscillator. Th 3rd wire is feedback. The oscillator will produce 110v AC. That's why it is so loud.
