Abstract

The invention relates to a hand controlling type tone switching device used for a 21-string Chinese harp. The invention is characterized in that an arc-shaped wooden frame is arranged at the lower part, legs are arranged at the both ends of the wooden frame. The two legs are fixed at the both ends of the width of the Chinese harp, a straight line type 21-seat tone switching device is arranged on the arch surface of the wooden frame, the lower end of a reverse T-shaped connecting plate is arranged on the side surface approximately in the middle of the wooden frame, 21-groove arc-shaped cover is arranged at the upper end of the connecting plate, and blocking plates are arranged at the both ends of the Chinese harp tone switching device. The invention has the advantages that by adopting the hand controlling type tone switching device for 21-string Chinese harp, six tones are available for the Chinese harp to switch, namely, A, D, G, C, F and B tone, the operation is fast and convenient, the tone accuracy reaches 100 percent without rebounding, each seat of tone switching device can work separately, no noise is generated, the technical blank of the tone switching for Chinese harp is filled up, and the expressive force of the Chinese harp is improved.

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.
