Inventors:

Shin H. Chen - Chicago IL

International Classification:

G10D 300
G10D 108

US Classification:

84291

Abstract:

A wishbone shape articulated lateral drive assembly (19, 20) is mounted on the inner panel of the back plate (13) in a stringed instrument to energize and drive said plate (13) sideways causing sound box (15) panels to generate phase distinct vibrations as a result of sound boards' (12, 13) unison flapping movement so that clarity and response of tones improved. In order to combine the improved sound with the original sound of the instrument for increasing the tonal range, manual switching capability (21) is provided within the sound box (15) for selection of tone colors from outside the instrument. A treble enhancing assembly (45, 47) additionally is provided to brighten the instruments' sound in general and highlight the treble in particular so that tone color is improved beyond that which can be provided by conventional instruments.
