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 as the human body, so that the pronunciation quality of the huqin will not be affected, but the solid base has no resonance cavity, the overtones are not rich, the sound decays quickly, the reverberation is long, and the sound vibration is hindered. Pronunciation can't respond well

[0004] The existing piano horse is a hollow horse made of bamboo, which is a triangular three-sided drilled hole, and then two gaps are opened at the top of the horse. It is more common but more effective. The bridge of the pan-string huqin has grooves and gaps, and there is no specific structure. The disadvantage is that there are no noise filtering holes. It is not a hard material, and it is prone to vibration between the bridge and the resonance plate. Tight, resulting in jumping or slipping

[0005] The string waist horse is a unique part of Qinhu that is related to sound production. It is used to adjust the tension and tightness of the strings. Vibration, the existing erhu has a qianjin, and there are also those who call the qianjin a waist horse, but there is no string waist code with the above functions. The qianjin is unstable and will run away. There is no fixed distance between the inner and outer strings. The tensions of the strings affect each other and are not easy to control, so that the vibration of the strings cannot be fully transmitted to the body of the piano, and the overall resonance of the piano is affected, so the performance effect is affected.
