Series Qinhu

Abstract

The invention relates to a series of Qinhu, which is characterized in that spherical domed type sounding boards, paulownia sound beams and hard maple are taken as materials for preparing a bridge, wherein the sounding boards are provided with netted texture, press-molded and recombined by composite boards of paulownia wood. A string nut engaged with a nut is made of rosewood material, and a hollow base is made of two materials of Mum SPP and Acer mono. The series of Qinhu of the invention, which improves the congenital defects of the structure of traditional musical instruments as urheen, has the advantages that the invention provides the series products capable of forming different high, middle and low registers, stereoscopic harmonic overall of bow instrument groups can be formed, the compass of the string part of Chinese traditional music bands can be widened, performance effect of multiple sounds of string music of the music bands can be increased, and compatibility of the string part in Chinese national symphony and other parts can be enhanced.

Description

technical field [0001] The invention relates to a series of Qin Hu, which belongs to the field of stringed musical instruments. Background technique [0002] Qinhu is a new type of Chinese stringed instrument reformed on the traditional Erhu system. Each series of Qin Hu is a group of four, respectively named Qin Gaohu, Qin Erhu, Qin Zhonghu and Qin Dahu, to correspond to the treble, alto, alto and bass parts. The range covers three octaves. The traditional The pronunciation of the erhu is made of soft leather products, and python skin is the most used leather product, so the source of raw materials is difficult, and it also destroys the ecological balance. At the same time, it is easily affected by climate temperature and humidity. Cause the leather surface to collapse, corrode, crack, short service life, poor stability, large internal damping, bad treble, that is, high-frequency stuffiness, which greatly affects the performance effect. There is also a thin piece of wood o...

Each series of Qin Hu is a group of four, respectively named Qin Gaohu, Qin Erhu, Qin Zhonghu and Qin Dahu, to correspond to the treble, alto, alto and bass parts. The range covers three octaves. The traditional The pronunciation of the erhu is made of soft leather products, and python skin is the most used leather product, so the source of raw materials is difficult, and it also destroys the ecological balance. At the same time, it is easily affected by climate temperature and humidity. Cause the leather surface to collapse, corrode, crack, short service life, poor stability, large internal damping, bad treble, that is, high-frequency stuffiness, which greatly affects the performance effect. There is also a thin piece of wood on the inner side of the vibrating film, which is also useful on the violin. Wooden resonance board, the former can prolong the service life of the membrane, but python skin is still used, the latter resonance board has many layers and different materials, so it is not suitable for Qin Hu;

[0003] The base of the traditional erhu is mostly a wooden solid rectangular wooden support, which is closely matched with the bottom of the piano tube. It is only used to isolate it from the body. There are also metal piano tubes with a piano support on the outside to stabilize the piano tube and prevent the piano tube from sliding. , to ensure that the outside of the metal piano tube has a small area in contact with soft objects such
