Embodiment 1
[0054] Example 1: A double-sound beam Liuqin (single-sided double-sound beam structure)
[0055] Because the innovation of the present invention all concentrates on the resonance box, so this embodiment will focus on describing the structure and structure of the Liuqin resonance box, and other structures related to the Liuqin can be considered to be realized by prior art, and will not be described in this embodiment. Details.
[0056] The structure and structure of the present embodiment Liuqin resonance box: as Figure 4-Figure 8 , Figure 14 , Figure 15 , Figure 18-Figure 21 As shown, the box body of the resonance box is composed of panel 1 and bottom plate 2 (see Figure 5-Figure 8 ).
[0057] In the resonance box, two upper sound beams 6 (see Figure 4 and Image 6 ), the upper sound bracing 6 is a strip-shaped sound bracing member (see Figure 14 and Figure 15 ), one side of the two upper sound beams 6 is closely fixed on the inner wall of the panel 1, and the...
Embodiment 2
[0062] Example 2: A double-sound beam Liuqin (double-sided double-sound beam structure)
[0063] The difference between embodiment 2 and embodiment 1 is: the base plate 2 of embodiment 1 is a thick plate, and the inner wall of base plate 2 is not provided with double sound beams and groove structures, while the base plate of embodiment 2 is a thin plate, and the base plate The inner wall of 2 is provided with double sound beam and groove structure. The specific content is as follows:
[0064] like Figure 9-Figure 13 , Figure 16 , Figure 17 , as shown, two lower sound beams 7 are arranged in the resonance box (see Figure 10 and Figure 11 ), the lower sound bracing 7 is a strip-shaped sound bracing member (see Figure 16 and Figure 17), one side of the two lower sound beams 7 is closely fixed on the inner wall of the bottom plate 2, and the other side of the two lower sound beams 7 is suspended in the resonance box relative to the panel 1 (see Figure 11 ), the len...

Abstract
A double-sound-beam liuqin comprises a resonance box, a box body of the resonance box is formed by splicing a panel and a bottom plate, and the double-sound-beam liuqin is characterized in that two upper sound beams are fixedly arranged on the inner wall of the panel in parallel; a transverse groove and a longitudinal groove are arranged on the inner wall of the panel, wherein the transverse groove and the longitudinal groove are communicated with each other to form a transverse sound tunnel and a longitudinal sound tunnel; a transverse sound beam is fixedly arranged between the panel and thebottom plate, and the transverse sound beam and the two upper sound beams are combined to divide a space corresponding to the inner wall of the panel into six resonance areas. The double-sound-beam liuqin breaks through the constraint of the traditional design of the internal structure of the traditional willow resonator, boldly proposes a new improved design scheme, solves the problem that the traditional willow cannot give consideration to good resonance timbre and penetrating power in high, medium and low pitch areas, greatly enhances the penetrating power (low attenuation and long transmission) of the willow sound, and has a bright and rigid high pitch area and high sound quality. And the alto area is soft and moist, and the bass area is more mellow in tone quality.
Description
technical field [0001] The invention relates to a traditional Chinese plucked string instrument, in particular to a double-tone beam Liuqin. Background technique [0002] Liuqin, also known as Liuyeqin, Vajra Leg, and Tupipa, is a traditional Chinese plucked string instrument. Originally popular in Jiangsu, Shandong, Anhui and other provinces. It is now popular all over the country, mainly in Linyi, Shandong and northern Jiangsu. It is one of the pear-shaped speaker stringed instruments that have been popular among the people since the Tang Dynasty. Its shape, structure, and playing method are similar to Ruan. [0003] Today, Liuqin plays various roles in the field of Chinese music performance. In the national band, the Liuqin is a high-pitched instrument of the plucked-string instrument group, which has a unique sound effect and often plays an important main melody in the high-pitched area. Because its timbre is not easy to be covered and integrated by other instruments...
