Patent ID: 7105731

Claim:
A low noise vibrating string transducer comprising: a base plate coupled to a metal plate, wherein said base plate is further coupled to a stringed instrument, said base plate having a volume control knob and a securing clamp for securing strings of said stringed instrument; a bipolar magnet for varying tones of the stringed instrument; a conducting string further comprising a first end and a second end; said conducting string is connected to a tuning knob at said first end and wherein said conducting string is connected to said securing clamp at the second end such that said conducting string is made sufficiently taut by rotating said tuning knob said conducting string rests above said base plate on a bridge wherein said bridge is coupled to said base plate such that said bridge electrically isolates said conducting string from a second conducting string; an amplifier circuit; Said amplifier circuit is coupled to a power source; Said volume control knob is electrically coupled to said amplifier circuit; Said second end of said conducting string is electrically coupled to said amplifier circuit; said bipolar magnet is coupled to said metal plate such that at least a portion of said bipolar magnet is directly below said conducting string, wherein said metal plate is a ground plane for a portion of electronic circuitry, further reducing noise by properly grounding the portion of the electronic circuitry.
