Double-sound-beam five-string instrument

Abstract

A double-sound-beam five-stringed instrument comprises a resonance box, a box body of the resonance box is formed by splicing a panel, a bottom plate and side plates, and the double-sound-beam five-stringed instrument is characterized in that two upper sound beams are fixedly arranged on the inner wall of the panel in parallel; two first lower sound beams are fixedly arranged on the inner wall ofthe front half part of the bottom plate in parallel; two second lower sound beams are fixedly arranged on the inner wall of the rear half part of the bottom plate in parallel; an upper groove shaped like a Chinese character 'feng' is formed in the inner wall of the panel to form an upper sound tunnel shaped like a Chinese character 'feng'; a lower cross-shaped groove is formed in the inner wall ofthe front half part of the bottom plate to form a front half part cross-shaped sound tunnel; a lower cross-shaped groove is formed in the inner wall of the rear half part of the bottom plate to forma cross-shaped sound tunnel of the rear half part; a transverse sound beam is transversely arranged in the resonance cavity, and the transverse sound beam is arranged at the groove body positions of the left half portion and the right half portion of the groove shaped like the Chinese character 'feng'. According to the scheme, the problems that a high-pitch area cannot be lightened, a low-pitch area is not enough vigorous and mellow, and the piano sound penetrating power is not strong during playing of the five-string instrument in the past are solved.

Description

technical field [0001] The invention relates to a plucked string instrument, in particular to a banjo with double-sound beams. Background technique [0002] The five-stringed qin is a kind of plucked string instrument with a long history and relatively rare, belonging to a kind of Guqin.

[0003] The banjo is divided into upper and lower parts, which are composed of soundboard, string nails, string posts, strings and resonance box. The upper soundboard is mostly made of soft pine or fir wood. The length of the board is 40 cm, the width is 12 cm, and the thickness is 2 cm. At a distance of 2 cm from both ends of the sound board, five iron nails are nailed at one end as strings. The string nails, the distance between the nails is 2 cm; the other end is set with five small iron or wooden s...
