Embodiment 1

[0024] Such as Figure 1-2 As shown, the present invention provides a zither soundboard 2 is made of carbon fiber board, the thickness of the zither soundboard 2 is 1-3mm.

[0025] The preparation method of a kind of zither soundboard 2 prepared by the carbon fiber board provided by the invention is as follows: (1) carbon fiber is made into carbon fiber prepreg cloth by impregnating epoxy resin; (2) carbon fiber prepreg cloth is superimposed layer by layer (3) At a temperature of 130° C., a 500-ton press is used for one-time curing and hot pressing to obtain a guzheng soundboard of a carbon fiber board.

[0026] Through expert appraisal, the guzheng prepared with carbon fiber board provided by the present invention has significantly better resonance effect than the guzheng prepared with wooden board. The timbre of the zither and the extended lingering sound.

[0027] Measurements were carried out on the guzheng prepared by the carbon fiber guzheng soundboard provided by the ...

Embodiment 2

[0032] Such as Figure 1-2 Shown, a kind of zither soundboard is characterized in that, zither soundboard 2 and zither first board 1, bottom plate 4 with holes and zither tail board 3 are all made of carbon fiber board; the thickness of carbon fiber board is 1-3mm.

[0033] Guzheng soundboard 2 and zither first board 1, base plate 4 with holes and zither tail board 3 are made as follows: (1) make carbon fiber prepreg cloth by impregnating carbon fiber with epoxy resin; (2) carbon fiber prepreg cloth (3) At a temperature of 130°C, a 500-ton press is used for one-time curing and hot pressing to obtain the guzheng soundboard 2 and the first zither board 1 of the carbon fiber board. Base plate 4 and kite tail plate 3.

[0034] The guzheng made of the carbon fiber board zither soundboard 2, the first zither board 1, the bottom plate 4 with holes and the zither tail plate 3 has passed the expert appraisal. Improve the timbre of the guzheng and prolong the lingering sound.

Embodiment 3

[0037] Such as Figure 1-2 As shown, the present invention provides a kind of guzheng soundboard 2 is to make with carbon fiber and glass fiber composite plate, and the thickness of guzheng soundboard 2 is 1-3mm.

[0038] The characteristics of glass fiber are high tensile strength, high modulus of elasticity, good rigidity, and low price. Carbon fiber and glass fiber composite board can reduce the cost of guzheng.

[0039]The preparation method of the guzheng soundboard 2 of described carbon fiber and glass fiber is as follows: (1) carbon fiber and glass fiber are made carbon fiber prepreg cloth and glass fiber prepreg cloth by impregnating epoxy resin; (2) carbon fiber prepreg (3) At a temperature of 130 ° C, a 500-ton press is used for one-time curing and hot pressing to obtain carbon fiber and glass fiber composite panels. Soundboard 2 and zither first board 1, bottom plate 4 with holes and zither tail board 3.

[0040] The guzheng made of the guzheng soundboard made of ...

Abstract

The invention provides a Guzheng soundboard. The Guzheng soundboard as well as a Guzheng head board, a pored base board and a Guzheng tail board are all made of carbon fiber boards or carbon fiber and glass fiber composite boards. With respect to the Guzheng consisting of the Guzheng soundboard, the Guzheng head board, the pored base board and the Guzheng tail board which are all made of the carbon fiber boards or the carbon fiber and glass fiber composite boards, the characteristics of enhanced resonance, improved frequency response, durability, light weight and long service life of the Guzheng are achieved, the defects of cracking and deformation of a wooden material, influences of environment conditions and the like are avoided, and dual optimizations in structure and property are realized for the Guzheng instrument, thereby increasing the sound of the Guzheng, improving the tone of the Guzheng and prolonging the aftersound. For the Guzheng soundboard or the Guzheng consisting of the Guzheng soundboard, the Guzheng head board, the pored base board and the Guzheng tail board, which are made of the carbon fiber boards or the carbon fiber and glass fiber composite boards, a measurement is carried out within a range of 40-70db, and compared with a Guzheng made of a wooden soundboard, the Guzheng provided by the invention has sound intensity improved by 4.8-7.1% averagely.

Description

technical field [0001] The invention belongs to the technical field of musical instruments, and in particular relates to a zither soundboard. Background technique [0002] Guzheng is an ancient national musical instrument in my country. So far, it has a history of more than 2,000 years, which can be described as a long history. The guzheng's first board, panel, tail board, bottom board with holes and outer frame are closed to form a guzheng box, in which the first board, sound board, bottom board with holes, outer frame and transverse partition are closed to form a box. The resonance box of the guzheng. Since the Three Kingdoms period, the evolution and changes in the history of the guzheng have basically not changed the tradition of choosing wood for the guzheng. Usually the outer frame of the guzheng is made of mahogany, rosewood and other hardwoods or a metal frame with hardwood to ensure its good strength; the guzheng soundboard is made of relatively soft and light pa...
