Medium Surface Transducer with Wires - 4 Ohm 3 Watt Shipping:4-6 Days Details for item #3131Turn any surface wall table etc into a speaker with a surface transducer. This type of 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 and if it's pressed against a surface it turns the transducer into a speaker! Often these size transducers are pressed up against a
