Detailed embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0036] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0037] Referring to Figures 1 - 6 , the present invention provides a fifty-string plucked instrument, including:

[0038] Bracket 1;

[0039] Resonance box 2, arranged on bracket 1;

[0040] A pair of bridge pieces 3 are provided on the top surface of the resonance box 2;

[0041] A tension balance mechanism 4 is provided on the resonance box 2. Twenty-nine strings 5 are provided on the tension balance mechanism. Among them, both ends of twenty-one strings 5 are respectively connected to a pair of bridge pieces 3, and one end of the other eight strings 5 is connected to any one of the bridge pieces 3, and the other end is connected to the top surface of the resonance box 2 through a connecting member;

[0042] Multiple tuning mechanisms 6 are provided on the top surface of the resonance box 2, and the multiple tuning mechanisms 6 are respectively provided at one end of the string 5 close to the bridge piece 3.

[0043] By designing the connection positions of the twenty-nine strings 5, with the tension balance mechanism as the center, there are twenty-nine strings and twenty-one strings on both sides respectively, forming a concept of fifty strings, similar to the cooperation effect of the black keys and white keys of a piano. In this way, there are both pentatonic scale modes and heptatonic scale modes, which completely constitute the twelve-tone equal temperament, expand the range of the pitch of national musical instruments, increase the playing field of the instrument, and improve the playing performance of the instrument.

[0044] And a tension balance mechanism 4 is provided on the string 5, which can adaptively adjust the tension of the string 5 during the playing process, so that the tension of the string 5 remains uniform, and cooperate with the tuning mechanism 6 to tune the string 5, and can maintain a good sound quality effect.

[0045] In an embodiment of the present invention, the tension balance mechanism 4 includes:

[0046] A mounting plate 41 is provided on the top surface of the resonance box 2;

[0047] Multiple upright posts 42 are provided on the mounting plate 41. The multiple upright posts 42 correspond to the twenty-nine strings 5 one by one. A rotating member 44 is rotatably connected to the upright post 42 through a self-resetting member 43. A clamping groove 45 is formed on the rotating member 44, and the string 5 is used to be arranged in the clamping groove 45.

[0048] When the string 5 is plucked, the string 5 can drive the rotating member 44 on the upright post 42 to rotate slightly, forming a slight follow-up effect, so that the self-resetting member 43 stores energy, and then the self-resetting member 43 releases energy to make the rotating member 44 automatically reset, so that the string 5 always maintains a good tension state.

[0049] In an embodiment of the present invention, the self-resetting member 43 is a torsion spring.

[0050] In an embodiment of the present invention, a plurality of grooves 7 are formed on the back surface of the resonance box 2 along the length direction of the string 5, and the plurality of grooves 7 correspond to the plurality of strings 5 one by one. The grooves 7 and the strings 5 echo each other, which can effectively improve the intonation.

[0051] In an embodiment of the present invention, the tuning mechanism 6 includes:

[0052] The slide rail 61 is arranged on the top surface of the resonance box 2;

[0053] The sliding frame 62 is slidably connected to the slide rail 61. An upper clamping plate 64 is threadedly connected to the top plate of the sliding frame 62 through a bolt 63 (the bolt 63 is rotatably connected to the upper clamping plate 64). The bottom plate of the sliding frame 62 is elastically connected with a lower clamping plate 65. The lower clamping plate 65 is located directly below the upper clamping plate 64. The lower clamping plate 65 and the upper clamping plate 64 are used to clamp the string 5.

[0054] By adjusting the position of the sliding frame 62 on the slide rail 61, the tuning operation of the string 5 can be carried out, and by rotating the bolt 63, the upper clamping plate 64 and the lower clamping plate 65 are cooperated to clamp the string 5, avoiding large displacement of the string 5 during the performance.

[0055] In an embodiment of the present invention, a plurality of first through holes are formed on the bottom plate of the sliding frame 62. A first connecting column 66 is slidably penetrated through the first through holes. One end of the first connecting column 66 is connected to the lower clamping plate 65, and the other end is connected to the sliding frame 62 through a spring 67.

[0056] The spring 67 and the first connecting column 66 form an elastic force mechanism, so that the upper clamping plate 64 and the lower clamping plate 65 can effectively clamp the string 5.

[0057] In an embodiment of the present invention, a plurality of second through holes are formed on the bottom plate of the sliding frame 62. A second connecting column 68 is slidably penetrated through the second through holes. One end of the second connecting column 68 is connected to the upper clamping plate 64, and the other end is connected with a clamping block 69. The clamping block 69 is engaged with a clamping plate 610, and the clamping plate 610 is fixedly connected to the slide rail 61.

[0058] During the downward movement of the upper clamping plate 64, the clamping block 69 is driven by the second connecting column 68 to engage with the clamping plate 610, thereby limiting the position of the sliding frame 62 on the slide rail 61, realizing the synchronous fixation of the sliding frame 62 and the string 5. The clamping block 69 and the clamping plate 610 are in a matching serrated structure.

[0059] In an embodiment of the present invention, a pair of sliding grooves 611 are formed on the opposite inner side walls of the slide rail 61. A pair of sliding blocks 612 are connected to the sliding frame 62. The sliding blocks 612 and the sliding grooves 611 correspond to each other and are slidably matched. Through the sliding blocks 612 and the sliding grooves 611, the sliding stability of the sliding frame 62 on the slide rail 61 can be effectively improved.

[0060] In an embodiment of the present invention, the slide rail 61 is adhesively bonded to the top surface of the resonance box 2, and the mounting plate 41 is adhesively bonded to the top surface of the resonance box 2, without changing the structure of the resonance box 2, so that the resonance box 2 maintains a good resonance effect.
