High-volume Erhu cylinder

Abstract

The invention discloses a high-volume Erhu cylinder, comprising a cylinder part, a rod, skin, a bridge and a string. The skin is bonded at a front end of the cylinder part. The bridge is clamped between the skin and the string. The cylinder part is composed of a first cone-shaped rib part, a protruding arc part and a second cone-shaped rib part. The first cone-shaped rib part and the second cone-shaped rib part are arranged at two sides of the protruding arc part respectively. The maximal aperture of the second cone-shaped rib part is larger than the maximal aperture of the first cone-shaped rib part. According to the high-volume Erhu cylinder provided by the invention, the resonance frequency range of the cylinder is widened, the volume is increased, the tone is soft and beautiful, the timbre is pure, the sensitivity is high, and a performance of large force can be born. Thus, under a precondition that the tone and the timbre are guaranteed, the Erhu volume is effectively increased, and thus the application range of Erhu is expanded, thereby facilitating spread of traditional culture.

Description

technical field [0001] The invention relates to a musical instrument, in particular to a high-volume erhu tube. Background technique [0002] The history of Erhu can be traced back to the Tang Dynasty, and it has become a uniquely attractive stringed instrument in my country. The structure of the erhu is relatively simple, consisting of nine main parts: the qin tube, the qin rod, the qin skin, the peg, the strings, the bow rod, the jack, the bridge and the bow horsetail; in the structure of the erhu, the qin tube and the Mongolian The piano skin on the piano tube is the most important sound-generating component. The strings vibrate under the friction of the bow horsetail, the piano skin vibrates through the piano bridge, and the piano tube resonates to produce sound. However, the prior art is difficult to further effectively increase the volume of the erhu under the premise of ensuring the sound quality and timbre of the erhu, thereby limiting the application range of the e...

Problems solved by technology

However, it is difficult for existing technologies to further effectively increase the volume of Erhu on the premise of ensuring the sound quality and timbre of Erhu, thus limiting the scope of application of Erhu, which is not conducive to the spread of traditional culture

For example, for the impromptu performance after gossip, due to the limitation of the environment, the lower volume will make it difficult for the audience to hear, but it is difficult to avoid the deterioration of the sound quality and timbre of the erhu by simply increasing the volume, so as to affect the interest of the audience
