Piezo Buzzer 40mm with Cable

The Piezo Buzzer 40mm with Cable is a larger-format pre-wired piezoelectric disc element designed to pick up sound or vibrations in musical instruments and electronic sensing systems. With a 40mm diameter, this buzzer provides higher sensitivity and broader surface contact, making it a great choice for DIY instrument builds such as cigar box guitars, foot stompers, or custom pickups in acoustic instruments.

Unlike smaller buzzers, the 40mm disc offers enhanced signal response and richer tones, especially when used as a contact microphone. The unit comes pre-wired with red and black leads for plug-and-play integration — no soldering required. Just glue or tape it to your project surface and wire it into your circuit. Ideal for makers, musicians, educators, and electronics hobbyists alike.
