Hi all,
Just starting out with my little amplifier project and I just have a couple quick questions regarding the piezo pickup portion.
I bought a Radioshack piezo buzzer, opened it up and got the piezo element out and I also have my 1/4" mono audio jack but I am unsure of what to connect.
Firstly, for the piezo, it has three different contact points:
What is the purpose of the center region connected to the blue wire? I am guessing that the brass is the grounding connection and the larger crystal portion is the signal. No idea what the small portion is for though.
Also, once I figure out the connections for ground and signal for the piezo, where would I be connecting them to the 1/4" mono audio jack? This is the jack that I have:
Thanks a lot!
