Double-arc Chinese zither

Abstract

The invention discloses a double-arc Chinese zither in the field of plucked instruments. The double-arc Chinese zither includes a hollow resonance body consisting of a face plate of upper part, a base plate of lower part, end plates at two ends and front and back side plates. Three ways of bass bars are vertically arranged in the resonance body with a certain spaced distance; a sound hole is arranged in the base plate; the face plate presents upward and raised arc transition from the front side plate to the back side plate and is provided with a Chinese zither horse, a plurality of strings are erected on the Chinese zither horse and fixed with the resonance body at two ends; the diameter of strings gradually thins from the front side plate to the back side plate; and the base plate also presents upward and raised arc transition from the front side plate to the back side plate. In fabrication, the base plate is formed by bending a flat plate, after the Chinese zither is made, the upper surface of the base plate is in a stretching and tension state, has stronger elasticity and can cause sound wave to be better reflected and resounded in the resonance body; acoustic energy attenuates slightly for long time; as the base plate can better coordinate with the face plate for resonance, the timbre of the Chinese zither becomes clearer and more far-reaching, mellower and more lingering. According to the technical proposal, a high-grade Chinese zither can be made.

Description

technical field [0001] The invention relates to a plucked string instrument, in particular to a guzheng. Background technique [0002] The structure of the zither in the prior art mainly includes a hollow resonance body composed of an upper panel, a lower bottom plate, end plates at both ends, and front and rear side plates. There are three sound beams standing upright at a certain distance, the bottom plate is provided with sound holes, and the panel is an upward convex arc transition from the front side panel to the rear side panel. The end of the string is fixed to the resonator; the diameter of the string is gradually reduced from the front side plate to the rear side plate; the pitch of the thick string is low, and the pitch of the thin string is high. When playing, the player plucks the strings facing the rear panel of the guzheng, the strings vibrate, and after resonating through the resonator, the sound is emitted from the sound hole. Its shortcoming is: the bottom...

AI Technical Summary

Problems solved by technology

Its shortcoming is: the bottom plate of existing zither is connected between the front side plate and the lower part of the rear side plate, the bottom plate is a flat plate, and the sound wave is reflected in a plane when it encounters the bottom plate in the resonator, and the bottom plate is not tensioned, and the sound emitted The tone is not clear and mellow enough
