ABSTRACT:
A vibrato assembly for stringed instruments makes slight and rapid changes in the pitch of the tone produced by stringed instrument. Previously known vibrato assemblies use knife-edge hinges or rolling ball bearings to produce these variations. The vibrato assemblies described herein use flexure bearings to produce variations in the tension of the strings and thereby the pitch of the tones. These flexure bearing vibrato assemblies have the advantages of high strength, zero operational noise and rumble, and virtually zero friction and hysteresis. Additionally, flexure bearing vibrato assemblies provide a robust path between the instrument and the strings resulting in improved tonal quality, range, and sustain.
