Abstract

PURPOSE:To obtain good acoustic characteristics by installing opposite strings opposite strings for playing which are fixed to the surface diaphragm of the stringed instrument. CONSTITUTION:The stringed instrument 20 is provided with the strings 28 opposite the strings 25 for playing. The strings 28 generate tension 2A by a peg 23. The tension 2A cancels tension 29 generated by the strings 25 for playing at a bridge 24, and bending moment on the top sound board which is generated by a conventional stringed instrument can be prevented from being generated. Namely, the strings 28 opposing the tension of the playing strings 25 of the stringed instrument 20 are provided to reduce the load on the top soundboard, and extra strength which is provided for the tension of the playing strings 25 is eliminated to make the top soundboard vibrate more easily. Further, the strings 28 opposing the tension of the playing strings 25 are used for the stringed instrument to lower the rigidity of the top soundboard, and the vibration characteristics are improved. Further, the strings 28 are tuned corresponding to a music tone and harmonic overtone by the resonance of the strings 28 are generated more to improve the tone quality.

This has the following drawbacks. In order to obtain good characteristics in a stringed instrument, it is necessary to improve the movement of the surface vibration plate 11. However, in the conventional structure, tension 17 is generated by the string 15 and the surface vibration plate 11 has a large force due to the tension 17 and A moment 18 is generated. In order to counteract these forces, the surface vibration plate 11 needs to have a large strength, and this large strength hinders the movement of the surface vibration plate 11 and adversely affects the acoustic characteristics.
