COMPONENTS & PARTS / OTHER / LARGE SURFACE TRANSDUCER WITH WIRES - 4 OHM 5 WATT
DESCRIPTION
Turn 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 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 flat surface to turn it into a sounding

board. The effect is a surprisingly clear sound that comes from the surface itself. The body of
the transducer is heavy so that it can be placed with the top down on a table. And for another
fun trick, put the transducer at the end of a large plastic cup to point sound in a particular
direction.
This transducer is about 45mm in diameter and has 4Ω impedance and should be run at about
5W. It's slightly larger than the Medium Surface Transducer. It pairs great with any of our audio
amps such as the TS2012 breakout, MAX98306, or you can even try the 20W amplifier, just
keep the gain down so you don't overdrive the transducers. Just connect it as you would any
other speaker, we even have some wires pre-soldered on.
