This speaker does not have a moving cone like most speakers, instead there is a metal rod wrapped with the voice coil. When current is pulsed through the coil the metal will expand and contract – and once pressed against a flat surface or cavity it becomes a speaker!

Pressed against your jaw or ear bone turns your skull into a speaker cavity – the result being sound seeming to originate within your head that no one else can hear!

If you plan to use the bone conduction transducer for prolonged direct contact with skin, we recommend that cover the transducer and wire connections to prevent accidental shorting of driver current through the skin, due to sweat and electrolyte accumulation around the metal parts.

This has 8 ohm impedance and should be run at about 1W. It pairs great with the TPA2012 breakout – just connect it as you would with any other speaker!
