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

Often, these size transducers are pressed against the jaw or ear bone to turn the skull into a speaker cavity. The effect is a sound of perfect quality that comes from inside your head and that no one else can hear. You can also press it against the elbow bone and put a finger in the ear to hear the audio transmitted by the arm! As there is no need for air, we have seen this type of module covered with plastic so that it can be used for waterproof headphones for swimmers. Other fun tips you can try: press against a table or wall to make a flat speaker, or at the end of a plastic cup to point the sound in a particular direction.

If you plan to use the bone conduction transducer for prolonged direct skin contact, we recommend covering the transducer and wire connections with something to prevent accidental shorting of the conductor current through the skin due to perspiration and electrolyte build-up around the metal parts.

This transducer is light and small and has an impedance of 8 ohms and should operate at about 1W. It fits perfectly with any of our audio amplifiers like TS2012 or MAX98306. Just connect it like any other speaker.
