[0054] Because the innovations of the present invention are all concentrated on the resonance box, so this embodiment will focus on describing the structure and structure of the pipa resonance box, and other structures about the pipa can be considered to be realized by the prior art, and will not be described in this embodiment. Details.
[0055] The structure and structure of the pipa resonance box of the present embodiment: 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 ).
[0056] In the resonance box, two upper sound beams 6 (see Figure 4 with Image 6 ), the upper sound bracing 6 is a strip-shaped sound bracing member (see Figure 14 with Figure 15 ), one side of the two upper sound beams 6 is closely fixed on the inner wall of the panel 1,...
[0062] 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:
[0063] Such as Figure 9-Figure 13 , Figure 16 , Figure 17 , as shown, two lower sound beams 7 are arranged in the resonance box (see Figure 10 with Figure 11 ), the lower sound bracing 7 is a strip-shaped sound bracing member (see Figure 16 with 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 ), ...

Abstract
A double-sound-beam lute 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 lute is characterized in that two uppersound 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 the bottom 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 lute breaks through the constraint of the traditional design of the internal structure of the traditional Chinese lute resonator, boldly proposes a new improved design scheme, solves the problem that the traditional Chinese lute cannot simultaneously have 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 Chinese lute sound, and has a bright and rigid high pitch area and a good sound effect. 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-sound beam pipa. Background technique [0002] Pipa is a traditional Chinese plucked string instrument with a history of more than two thousand years. The earliest musical instrument known as the "pipa" appeared around the Qin Dynasty in China. Pipa is the first plucked stringed instrument, a plucked-stringed string-sounding instrument. Made of wood or bamboo, the resonance box (sound box) is half pear-shaped, with four strings on it. It was originally made of silk thread, but now it is mostly made of steel wire, steel rope, and nylon. The neck and panel are used to determine the "phase" and "quality" of the phoneme. When playing, hold it vertically, press the strings with your left hand, and play with the five fingers of your right hand. It is an important national musical instrument that can be played solo, accompaniment, ensemble, and ensemble. ...
