Abstract

The invention discloses a string-lifting modulation device for a 21-stringed Guzheng. The string-lifting modulation device is characterized in that the right side of a rear beam extends to be widened, the widened width equals the length of a set of modulation device, the upper part of the extended and widened right side of the rear beam is provide with a metal plate strip of the same size, and uniform 21-set string-lifting modulation devices are arranged on the metal plate strip. The string-lifting modulation device for the 21-stringed Guzheng has the advantages that 6 keys, namely the A key, the D key, the G key, the C key, the F key and the B flat key, can be modulated on the Guzheng, the intonation does not rebound, the modulation does not occupy any part of a panel of the Guzheng, thereby providing complete space and complete Guzheng resonance region for the performer, and further improving the expressive force of the Guzheng.

Description

String modulation device lifted by 21 string Zheng

Technical field

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

Background technology.

Also have ' Zheng ' modulation device in current national musical instruments field, but there are problems in apparatus structure: what have destroys original moulding; What have is placed in resonant tank by the device of heaviness; And affect sympathetic response heavily again, the increase pedal also had; Cause and carry trouble, and fatal be a bit that after ubiquity modulation, sound is forbidden, also reliable pressure string modulation, but do not catch up with the best unified specification of current Zheng, utilization cannot be installed, so the propagation and employment of Zheng modulation is very micro-so far, still rests on and come on the primitive approach of modulation by mobile zither code.

Summary of the invention

The object of the invention is to solve Zheng modulation: what have destroys original moulding; What have is placed in resonant tank by the device of heaviness; And affect sympathetic response heavily again, the increase pedal also had; Cause and carry trouble, and fatal a bit: after ubiquity modulation, sound is forbidden, also reliable pressure string modulation, but do not catch up with the best unified specification of current Zheng, utilization cannot be installed, so the propagation and employment of Zheng modulation is very micro-so far, still rest on the problem carrying out modulation by mobile zither code.

String modulation device lifted by technical solution of the present invention design 21 string Zheng, its feature: extend on the right of back hills and widen, the width widened is the length of a Transponder, extending the laths of metal that one piece of same size is added on the top widened on the right of back hills, laths of metal is string Transponder lifted by the same form 21 Zheng.Advantage of the present invention is that string modulation device lifted by 21 string Zheng, from then on Zheng can not only turn 6 tune, that is: A, D, G, C, F and fall B adjust, accuracy in pitch does not rebound, and modulation device does not account for any position of Zheng panel, therefore, for player provides complete space and complete Zheng resonance region, more perfect Zheng expressive force.

Embodiment

Fig. 1 is left oblique view of the present invention, it is a Transponder duty in figure, bottom is Transponder base angle 1, one edged surface at base angle 1 is fixed on the laths of metal 19 that to extend on the right of back hills and widen, the left end of another edged surface is obtuse angle shape handle 2, the middle part of obtuse angle shape handle 2 is fine setting angles 3 of chamfer shape, fine setting angle 3 one edged surface is fixed on obtuse angle shape handle 2, another edged surface is double-deck, double-deck plane is two holes 4 respectively, two holes 4 are installed with two screws 7 respectively, centre is nut 8, nut 8 is rotary with screw 9, the middle and lower part of obtuse angle shape handle 2 is that square lifts the angle of chord 5, lift the angle of chord 5 one edged surface near obtuse angle shape handle 2, another edged surface is double-deck, the plane of bilayer is respectively two nuts 6, two nuts 6 are rotary with two screws 7, the bottom righthand side lifting the angle of chord 5 is double-deck, bilayer there is linchpin 10, linchpin 10 is miniature bearings 11, what have string slot in the middle of bearing 11 is moulds overcoat 12 processed, the upper end of obtuse angle shape handle 2 moulds sleeve 13 processed, the right-hand member at base angle 1 is limit for height block 14, the top of limit for height block 14 is linchpin 15, linchpin 15 is miniature bearings 16, what have string slot in the middle of bearing 16 is moulds overcoat 17 processed, base angle 1 about in the middle of be the little frame 18 of handle.

Fig. 2 is left oblique view of the present invention, is that the same form 21 Transponders 13 treat work state in figure, and extending on the laths of metal 19 widened on the right of back hills is the same form 21 Transponders 13, string 23, zither code 24, panel 27.

Fig. 3 is vertical view of the present invention, and in figure, 21 string Zheng are lifted string modulation device 13 and extended on the laths of metal 19 widened on the right of back hills, zither head 20, mountain, string hole 21, Qian Yue, front end 22, string 23, zither code 24, back hills 19, string hole, rear end 25, zither tail 26, panel 27.The same form 21 is lifted string Transponder and is divided into four groups, and often group has five, and the 5th group one is lifted string Transponder is independent handle, the same form 21 is lifted string Transponder and is being treated man-hour, (under state of nature), the right side (the first direction of zither) swung to by handle, and now Zheng basis is adjusted to A tune.The present invention lifts string Transponder 13 modulation by extending the same form 21 on the laths of metal 19 widened on the right of back hills, because of the technique made, thus simple operation, every Transponder works independently, without sound, and accuracy in pitch a hundred per cent.
