Bone Conductor Box

Turn almost anything into a speaker with a bone conductor transducer and Adafruit's TPA audio amplifier.

If your next project needs some sound, a bone conductor transducer will have you experimenting with all sorts of objects. If you've ever wired a speaker system before, you'll find this DIY electronics project is fun and easy!

This incredible speaker does not have a moving cone like most speakers you've seen, instead, a small metal rod is wrapped with the voice coil. When current is pulsed through the coil, the magnetic field causes a piece of metal to expand and contract - if pressed against a flat surface or cavity it turns it into a speaker!
