Abstract

A stringed musical instrument device that functions as a peripheral for a computer or computing device, whereby electronic transducers placed inside and/or outside the instrument convert the vibrations of the strings and/or the instrument body from an analog electrical signals to digital signals. The digital signals are then transmitted via Class Compliant USB and/or FireWire-IEEE 1394 and/or IEEE 802.11 wireless and/or Bluetooth® wireless protocols to any computer or computing device that accepts data via those protocols. This device requires no external power, amplification, analog-to-digital conversion, software or hardware. This device is an improvement over the prior art in that it accurately and immediately represents on a computer or computing device the signals that are being sent from the instrument and reduces the number of devices needed to accomplish the task of sending digital signals to a computer or computing device.

Claims

1. A stringed musical instrument device that also functions as a peripheral for a computer or comparing device, comprising:

a body having a soundboard;
