Problems solved by technology

The series of Qin Hu consists of four pieces, which are 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 waist horse is a unique part related to Qin Hu's sound production. It is used to adjust the tension and tightness of the strings. It reacts with the jack to increase the tension of the strings, and even transmits the vibration of the strings to the piano bar to make the head vibrate. , the existing erhu has a qianjin, and there is also a qianjin called a waist horse, but there is no string string waist horse with the above functions. The qianjin is unstable and will run the 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.

Embodiment Construction

[0023] The string-waisted horse matched with the series Qin Hu Qianjin is shown in Figures 1 and 2. It uses rosewood material to make a flat quadrangular pyramid body. The front and rear cone surfaces 2 of the cone body are equilateral triangles. The open string groove 1 supporting the strings has a top cone width of 5-5.5mm, a top cone thickness of 1.5-1.8mm, and a distance of 2.0-2.5mm between the two open string grooves supporting the strings, so that the inner and outer strings have a certain Fixed distance, the tension of the strings does not affect each other when the inner and outer strings are tuned, and the tension of the strings does not affect each other when the inner and outer strings are tuned, so that the tension of the strings is increased. There is a semicircular hole at the bottom of the cone that matches the bar 4. There is a thread perforation for fixing the piano bar above the semi-circular hole of the opening 3. The string waist horse is fixed on the piano...

Abstract

The invention relates to a bridge engaged with a Qianjin of series of Qinhu, which is characterizes in that the invention selects rosewood material to make into a rectangular pyramid cone with flattened shape, the top portion of the pyramid is equipped with two open slots which is used to support the strings, the bottom is equipped with a semi-circle hole with opening, the upper portion of which is equipped with string through holes, the length of edge of the left pyramid surface is bigger than that of the right one of the pyramid cone, the edge of the left pyramid surface is sloping edge, the edge of the right pyramid surface is straight edge, which are formed into non-equilateral right-angle pyramid surface. The product has the advantages and effects that the invention can make the fixed distance of the inner and outer strings and the stretching force of the strings when setting tone doesn't influence with each other, the vibration of the strings can be sufficiently conducted to the Qin body, the integral vibration of the Qin is strengthened, the bridge and the Qianjin form a reverse force to strengthen the stretching force of the strings.

Description

technical field [0001] The invention relates to a stringed waist horse matched with a series of Qinhu jacks, which belongs to the field of stringed musical instrument parts. Background technique [0002] Qinhu is a new type of stringed instrument reformed on the traditional Erhu system. The series of Qin Hu consists of four pieces, which are 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 waist horse is a unique part related to Qin Hu's sound production. It is used to adjust the tension and tightness of the strings. It reacts with the jack to increase the tension of the strings, and even transmits the vibration of the strings to the piano bar to make the head vibrate. , the existing erhu has a qianjin, and there is also a qianjin called a waist horse, but there is no string string waist horse with the above functions. The qianjin is unstable and will run the strings....
