Tilt-shift erhu with sound window in waist

Abstract

The invention relates to a tilt-shift erhu with a sound window in the waist. The tilt-shift erhu comprises an erhu neck and an erhu canister, the erhu neck is arranged at the upper end of the erhu canister, skin is arranged at one end of the erhu canister, and the sound window is formed in the other end of the erhu canister; the sound window comprises an arc-face sound window body and a polygonal-face sound window body, the arc-face sound window body is located on the front face of the erhu canister, the polygonal-face sound window body is located on the end face of the erhu canister, and the arc-face sound window body and the polygonal-face sound window body are arranged in an adjacent mode; the erhu neck is arranged at the 2 / 5 position of the erhu canister and is close to the skin end. By means of the tilt-shift erhu, as the neck is titled, namely the position of the erhu neck of the erhu is changed, generated high-frequency sounds can be strengthened, and low-frequency vibration can be enlarged; the structure of the erhu canister is changed, the abnormal-shaped sound window is formed in one end of the erhu canister, the problem of vibration of a high sound region can be solved, the sound quality of the high sound region is improved, and the sound quality of a middle sound region and a low sound region is not influenced; the area of the skin and the width of edge skin are controlled, it can be guaranteed that incapability of high sound generation due to the fact that the high sound region is rapidly collapsed is avoided after large pull force is borne, and the tilt-shift erhu is not influenced by the damp environment, and the service life is prolonged.

Description

technical field [0001] The invention relates to an erhu in the field of folk musical instruments, in particular to a shaft-shifting erhu with a window at the waist. Background technique [0002] The erhu is a national musical instrument with a long history in China. The erhu includes qin bars, strings, qin tubes, qin shafts, qin rests, and qin bows. There are skins and sound windows on the qin tubes. Side hexagon or equilateral octagon, the sound window is set on one end of the piano tube. [0003] For example, the publication number is CN201392646, and the publication date is that the Chinese utility model patent document on January 27, 2010 discloses a kind of erhu with adjustable sound effects, including a piano tube, a piano bar, a piano shaft, a piano string, a piano bracket, and a piano bow. And the qin skin and the sound window that are installed on the front and rear ports of the qin tube respectively, the qin tube is composed of a plurality of plates, and the qin t...

Problems solved by technology

Then, in order to improve the vibration effect in the high-pitched area based on the traditional qin tube structure, the practice of shortening the length of the qin tube appeared. When the length of the qin tube was shortened, the vibration effect in the high-pitched area was improved. , and will destroy the timbre of the bass area, so how to balance the two is a big problem
