How Do You Make A Piezo Transducer?
A piezo transducer pickup is a fun and inexpensive way to record your acoustic guitar or even play it through an electric guitar amplifier to use effects like distortion and delay. The pickup is made out of a piezo buzzer element, which can be purchased at many electronics stores for as little as $3. The piezo buzzer’s transducer element, when wired correctly, acts as a small microphone, transferring any sound made by your acoustic instrument into a usable electronic signal. Carefully break open the piezo buzzer. Remove the round metal transducer element from inside the buzzer. This is what will act as your pickup or microphone. Use wire strippers to remove the rubber shielding from the ends of a 1-foot shielded audio cable. You should see a red wire (the signal wire) and a black wire (the ground wire) on the inside of the cable’s shielded casing. Solder the signal wire (the red wire) to the center of the piezo buzzer transducer element. This is the part of the transducer that detects
