Electronic string instrument with bend detector
First Claim
1. An electronic musical instrument of the stringed type, wherein sounds are produced by the performer by interacting with the strings of the instrument, and wherein bending of a string causes an alteration of a parameter of the sound produced, comprising,an instrument having a plurality of strings,tone generator means responsive to said performerstring interaction for producing an audio output,a Hall effect device, which outputs an electrical signal,a permanent magnet disposed in spaced relation to the Hall effect device,means responsive to the bending of a string for causing an alteration in the spacing between said Hall effect device and said permanent magnet for causing a variation in the electrical signal outputted by the Hall effect device, andmeans responsive to said variation in electrical signal for causing a change in a parameter of said audio output which is produced by said tone generator means.

Abstract
An electronic musical instrument of the stringed type wherein bending of a string results in a change in a parameter of the sound produced. At the bridge of the instrument, each string is connected with a leaf spring which is moved towards the nut end of the instrument when the string is bent. Each leaf spring is connected with a Hall effect device, and the spacing between it and a permanent magnet is changed when the spring moves, thus causing a variation in the output of the Hall effect device, which variation alters a parameter of the audio output produced by a tone generator means.
