Patent ID: 7514614

Claim:
A musical instrument comprising: a substantially rigid body frame having an aperture therethrough; a neck secured to the body frame at a first location; a plurality of strings having first ends and second ends and attached to the neck at the first ends and attached to the body frame at a second location distal the first end, the strings under tension; at least three suspension couplings located at least at third, fourth and fifth locations of the body frame proximate the aperture; a soundboard assembly disposed at the aperture and attached to the suspension couplings the suspension couplings resonantly isolating the soundboard from the body frame, the soundboard assembly having a soundboard comprising a first plate; a bridge secured to the soundboard, the plurality of strings urged against the bridge by the tension of the strings; a transducer having a coil in resonant communication with the soundboard, the soundboard assembly further comprising a magnet structure support comprising a second plate, the soundboard assembly further comprising a separation between the first and second plates defining a chamber between the first and second plates, the second plate having a second aperture therethrough; the transducer having a magnet structure attached to the second aperture of the second plate of the soundboard assembly, the transducer coil attached to the soundboard and suspended in magnetic communication with the magnet structure, whereby: relative motions of the soundboard and second plate cause relative motions of the voice coil and magnetic structure, inducing an electrical output signal.
