Description

The simple and easy string modulation device of lifting of 21 string Zheng

Technical field

The present invention relates to national musical instruments Zheng modulation device, a kind of 21 string Zheng are lifted the string modulation device

Background technology.

At present in the national musical instruments field Zheng modulation device is arranged also, but the apparatus structure existing problems: the destruction that has original moulding; The device with heaviness that has is placed in the resonant tank; And influence sympathetic response heavily again, the increase pedal that also has; Cause and carry trouble, and fatal a bit be that sound is inaccurate after the ubiquity modulation, so the popularization of Zheng modulation so far with use very littlely, still rest on and lean on mobile zither sign indicating number to come on the original means of modulation.

Summary of the invention

The objective of the invention is to solve Zheng modulation: the destruction that has original moulding; The device with heaviness that has is placed in the resonant tank; And influence sympathetic response heavily again, the increase pedal that also has; Cause and carry trouble, and fatal a bit be: sound is inaccurate after the ubiquity modulation, thus the popularization of Zheng modulation so far with use very littlely, still rest on and lean on mobile zither sign indicating number to come the problem of modulation.

Technical scheme of the present invention designs 21 Zheng and lifts the string modulation device, its characteristic: the bottom is the arch crane span structure, and the length of arch crane span structure is the width of Zheng; There is pin at the crane span structure two ends, and bipod is fixed on Zheng width two ends, are that 21 of the same form are lifted the string Transponder on the crane span structure arch face; The central approximately side of crane span structure is a projection; Projection connects inverted T-shaped web joint lower end, and the web joint upper end is 21 groove arc covers, and 21 are lifted string Transponder two ends is baffle plates.Advantage of the present invention is that 21 Zheng are lifted the string modulation device, and from then on Zheng can change 6 accent, that is: A, D, G, C, F and fall B and transfer; And string is not hindered in simple operation, and accuracy in pitch absolutely; Do not rebound, every Transponder works independently, no sound; It is blank to have filled up Zheng modulation, perfect Zheng expressive force.

Fig. 3 is a rear view, Transponder duty among the figure, and the bottom is a Transponder base 1, and the right-hand member of base 1 is an obtuse angle shape handle 2, and the upper end of obtuse angle shape handle 2 is taper knobs 13.

Fig. 4 is a rear view, and a Transponder is treated worker's state among the figure, and is the same.

Fig. 5 is a vertical view, and arch crane span structure 14 among the figure is a projection 15 in the middle of crane span structure 14 bottoms are about.

Fig. 6 is left oblique view, is that 21 Transponders of the same form are treated worker's state among the figure, and top is 21 Transponder taper knobs 13 of the same form, and 21 Transponder bottoms of the same form are arch crane span structures 14, and crane span structure 14 is a projection 15 in the middle of making an appointment with.
