{"title":"Medium Surface Transducer with Wires - 4 Ohm 3 Watt","handle":"medium-surface-transducer-with-wires-4-ohm-3-watt","url":"/products/medium-surface-transducer-with-wires-4-ohm-3-watt","description":"A medium surface transducer that turns any flat surface — tables, walls, panels — into a speaker. Unlike traditional cone speakers, a voice coil wrapped around a metal rod causes vibration that transfers directly to the surface it's pressed against, producing surprisingly clear sound from the surface itself.\n\nThe transducer has a heavy body so it can simply be placed top-down on a surface. It operates at 4 Ω impedance and 3 W, making it compatible with common Class D audio amplifier breakouts. Pre-soldered wires are included for easy connection.\n\nKey Features\n\n\nSurface-Driven Audio – Turns any flat surface into a speaker\n\nPre-Soldered Wires – Ready to connect to an audio amplifier\n\nHeavy Body – Stays in place on surfaces without mounting\n\n\nSpecifications\n\n\nDiameter – 28 mm\n\nImpedance – 4 Ω\n\nPower Rating – 3 W\n\n\nIdeal For\n\nInteractive audio installations\nHidden speaker projects\nDirectional sound experiments (e.g. mounted in a cup or tube)\nPairing with Class D audio amplifier breakouts\n\n\nPackage Contents\n\n1× Medium surface transducer with pre-soldered wires\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13122,"title":"Default Title","sku":"AF-1785","price":30.83,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":64,"option1":"Default Title"}]}
