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!\u003c\/p\u003e\n\u003cp\u003eOften 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.\u003c\/p\u003e\n\u003cp\u003eIf 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.\u003c\/p\u003e\n\u003cp\u003eThis transducer is lightweight and small and has \u003cstrong\u003e8 ohm\u003c\/strong\u003e impedance and should be run at about \u003cstrong\u003e1W\u003c\/strong\u003e. 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.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/bMnwgO8dxxQ?si=rljtYmhgt2dFcsQ1\u0026amp;start=421\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBone conduction transducer with metal rod and voice coil design\u003c\/li\u003e\n\u003cli\u003eNo moving cone – uses magnetic field to expand and contract metal for sound\u003c\/li\u003e\n\u003cli\u003eCan be pressed against bone or flat surfaces to create speaker cavities\u003c\/li\u003e\n\u003cli\u003eProduces sound perceived from within the head without external audio\u003c\/li\u003e\n\u003cli\u003eWaterproof design suitable for underwater use and swimming\u003c\/li\u003e\n\u003cli\u003eLightweight and compact form factor\u003c\/li\u003e\n\u003cli\u003e8 ohm impedance\u003c\/li\u003e\n\u003cli\u003eOperates at approximately 1W power\u003c\/li\u003e\n\u003cli\u003eCompatible with audio amplifiers such as TS2012 breakout and MAX98306\u003c\/li\u003e\n\u003cli\u003ePre-soldered wires included\u003c\/li\u003e\n\u003cli\u003eRecommended protective covering (such as Sugru) for prolonged skin contact to prevent electrical shorting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 14mm x 21.5mm\u003c\/li\u003e\n\u003cli\u003eWeight: 9.6g\u003c\/li\u003e\n\u003cli\u003ePower handling: 1 watt RMS\/2 watt max\u003c\/li\u003e\n\u003cli\u003eLe: 1.26 mH\u003c\/li\u003e\n\u003cli\u003eImpedance: 8 ohm\u003c\/li\u003e\n\u003cli\u003eRe: 5.8 ohms\u003c\/li\u003e\n\u003cli\u003eFrequency response: 300-19,000 Hz (but will vary with what you use as the transducer surface)\u003c\/li\u003e\n\u003cli\u003eFs: 1,600 Hz\u003c\/li\u003e\n\u003cli\u003eSPL: 90.1 dB 1W\/1m (but will vary with what you use as the transducer surface)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDatasheet\u003c\/li\u003e\n\u003cli\u003eDrawing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Bone Conductor Transducer with Wires - 8 Ohm 1 Watt\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":52217197723936,"sku":"shv1787257217104","price":5.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/3231\/3120\/files\/bone-conductor-transducer-with-wires---8-ohm-1-watt_1.jpg?v=1787257221","url":"https:\/\/www.elmwoodbasket.shop\/products\/bone-conductor-transducer-with-wires-8-ohm-1-watt","provider":"My Store","version":"1.0","type":"link"}
