Tone amplification erhu

Abstract

The invention discloses a tone amplification erhu, comprising an erhu barrel, erhu post, an erhu skin, bridges and strings. The erhu skin is pasted in the front of the erhu barrel; the bridges are clamped and fixed between the erhu skin and the strings; the erhu barrel consists of a first circular-truncated cone, a recess arc part and a second circular-truncated cone; the minimum cross profiles of the first circular-truncated cone and the second circular truncated cone are connected to the two ends of the recess arc part; and a plurality of grooves are arranged in the recess arc part. The tone amplification erhu barrel widens the resonance frequency range, increases volume, can bear intense playing and is soft and pure in the tone and high in sensitivity. As a result, the tone amplification erhu can increase the volume of the erhu, widens the application range of the erhu and is beneficial for propagation of the traditional culture.

Description

Technical field [0001] The invention relates to a musical instrument, in particular to an amplifying erhu piano tube. Background technique [0002] Erhu's history can be traced back to the Tang Dynasty, and it has now become a stringed instrument with unique charm in my country. The structure of the erhu is relatively simple, consisting of nine main parts: the piano tube, the shaft, the skin, the pegs, the strings, the bow shaft, the jack, the weight and the bow horsetail; The piano skin on the piano tube is the most important sounding component. The strings vibrate under the friction of the bow and horsetail. The piano code makes the piano skin vibrate, and the piano tube generates resonance and sounds. However, the existing technology 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 erhu and not conducive to the spread of traditional culture....

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
