Description

Manual mode inflexion device for 21-subtense Chinese zither

Technical field

The present invention relates to national musical instruments Zheng modulation device, a kind of manual mode inflexion device for 21-subtense Chinese zither

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 or the like, 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 by 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; The increase pedal that also has; Cause and carry trouble or the like, 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 the original means problem of coming modulation by mobile zither sign indicating number.

Technical solution of the present invention design manual mode inflexion device for 21-subtense Chinese zither, its feature: the bottom is wooden an of arch, wooden length is the width of Zheng, there is pin at wooden two ends, bipod is fixed on Zheng width two ends, is 21 Transponders of the same form on the wooden arching face, is inverted T-shaped web joint lower end on the side in the middle of wooden pact, the web joint upper end is 21 groove arc covers, and 21 string modulation device two ends are baffle plates.Advantage of the present invention is a manual mode inflexion device for 21-subtense Chinese zither, and from then on Zheng can change six accent, that is: A, D, G, C, F and fall B and transfer, and simple operation, accuracy in pitch does not absolutely rebound, and every Transponder works independently, no sound has been filled up the Zheng modulation blank, perfect Zheng expressive force.
