Bone Conductor Transducer with Wires - 8
Ohm 1 Watt
PRODUCT ID: 1674
Description
Drown out the voices in your head with a bone conduction transducer! 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!
Often these size transducers are pressed up against the jaw or ear bone to turn the skull into a speaker
cavity. The effect is a perfect quality sound that is coming from within your head that nobody else can hear.
You can also press it against your elbow bone and stick a finger in your ear to hear the audio transmitted
through your arm! Since no air is required, we've seen this kind of module covered in plastic so it can be
used for waterproof 'underwater' headphones for swimmers. Other fun tricks you can try: press it against a
table or wall to make a flat speaker, or at the end of a plastic cup to point sound in a particular direction.
If you plan to use the bone conduction transducer for prolonged direct contact with skin, we recommend
that cover the transducer and wire connections with something like Sugru to prevent accidental shorting of
driver current through the skin, due to sweat and electrolyte accumulation around the metal parts.
This transducer is lightweight and small and has 8 ohm impedence and should be run at about 1W. It pairs
great with any of our audio amps such as the TS2012 breakout or MAX98306. Just connect it as you would
any other speaker, we even have some wires pre-soldered on
