Huqin

Abstract

The invention relates to a Huqin. The Huqin comprises a qin rod, a qin shaft, a bow seat, a bow, a connection frame and a qin cylinder, wherein the qin shaft comprises a first qin shaft and a second qin shaft, one ends of the first qin shaft and the second qin shaft respectively penetrate through the upper end of the qin rod, the second qin shaft is arranged below the first qin shaft, the bow seat is arranged at the lower end of the first qin shaft, one end of the bow seat is fixedly connected with the qin rod through a first wooden screw, the bow is arranged between the bow seat and the qin shaft, the connection frame comprises a qin rod seat, an oblique groove arm and a qin cylinder hoop, a lower end of the qin rod stretches into and is fixed on the upper end of the qin rod seat, the qin rod seat is connected with the oblique groove arm, the oblique groove arm is connected with the qin cylinder hoop, the qin cylinder hoop is fixedly sleeved at an outer ring of the qin cylinder, the lower end is clamped through a screw, a distance from a connection portion of the lower end of the oblique groove arm and the upper end of the qin cylinder hoop to a central axial line of the qin cylinder is in a range of 5-10mm, and one end of the qin cylinder away from the qin cylinder hoop is sleeved with a qin cylinder back mouth hoop. Compared with the prior art, the Huqin has advantages of stable structure, intelligible, intensive and resonant sound, playing convenience, no cylinder crack and prolonged service life.

Description

technical field [0001] The invention relates to the technical field of national stringed musical instruments, in particular to a huqin. Background technique [0002] The erhu of the prior art all is that the qin bar is inserted in the qin tube, as figure 1 and figure 2 As shown; its main defects are: [0003] 1. The length of the rod inserted into the tube is 73.32mm, which greatly hinders and disturbs the refraction, conduction, resonance of the sound in the tube, and the formation of the sound column in the tube; [0004] 2. The position of the bow end, that is, the piano rod on the upper surface of the piano tube, protrudes 10 mm from the central axis, so that the bow hair cannot be moved perpendicular to the surface of the piano, and the sound of the piano is not sensitive enough, crisp, full, translucent; [0005] 3. There is no bow seat, and the bow hangs directly on the piano shaft when it is in the piano, which is very loose and not fixed; the main problems are ...

AI Technical Summary

Problems solved by technology

[0003] 1. The length of the rod inserted into the tube is 73.32mm, which greatly hinders and disturbs the refraction, conduction, resonance of the sound in the tube, and the formation of the sound column in the tube;

[0004] 2. The position of the bow end, that is, the piano rod on the upper surface of the piano tube, protrudes 10 mm from the central axis, so that the bow hair cannot be moved perpendicular to the surface of the piano, and the sound of the piano is not sensitive enough, crisp, full, translucent;

[0005] 3. There is no bow seat, and the bow hangs directly on the piano shaft when it is in the piano, which is very loose and not fixed; the main problems are as follows:

[0006] ① The rosin on the bow hair always sticks to the strings, making the strings astringent and affecting the flexibility of left fingering;

[0008] ③Bows are not collected during the interval between band rehearsals. The bows are not fixed, irregular, unstable, and thrown around. It is easy for players to collide with each other, which affects rehearsals;

[0009] ④The most important thing is that once the bow is hung, the bow's own gravity will slide down, the ponytail is easy to eat into the yard, and it is easy to be broken when taking the bow
