Description

Zheng with modulation device

The utility model relates to a kind of Zheng in national musical instruments field, relates in particular to a kind of Zheng with modulation device.

Zheng is the time-honored a kind of national musical instruments of China, and it comprises the resonator that is connected as a single entity with zither head zither tail between zither head, zither tail, the zither head zither tail, and the S of zither tail end is curved on the resonator panel, and the Yue Shan of zither head end and each root string constitute.The Zheng pronunciation is dulect, liked by people always, improving constantly particularly along with living standards of the people, the people of study Zheng is also more and more, but because Zheng is a five-tone scale, in the time of need playing other two scales, need realize that the personnel that play when needing modulation must realize by traditional modulation method of hand frameshit by the fingering of playing personnel.This modulation method occurs easily that modulation is inaccurate, face is long during frameshit, and even sign indicating number appears falling, therefore, the tradition Zheng is owing to be difficult for modulation, its development and extensively utilization have been influenced, make it and can not arbitraryly play with other musical instrument cooperation, this makes the development of Zheng bring immeasurable loss undoubtedly, also makes composers can't expand the thinking of creation Zheng song simultaneously.

The purpose of this utility model is on the basis of existing traditional Zheng five-tone scale, does not change original Zheng shape system, playing method, and a kind of modulation of can following one's bent is provided, to satisfy the different Zheng with modulation device of playing needs.

The purpose of this utility model is achieved through the following technical solutions: a kind of zither head that comprises, the zither tail, the resonator that is connected as a single entity with zither head zither tail, the S of zither tail end is curved on the resonator panel, the Yue Shan of zither head and the Zheng that starts from each range of sound string formation of the curved side of zither tail S with modulation device, it is characterized in that being provided with modulation device in the zither head cavity, modulation device comprises support, be nested with on support rotating shaft with tangential horizontal vertical, be nested with the cam of corresponding each string in the rotating shaft through key, correspondingly with each cam be provided with the fine setting connecting rod that the end has roller, fine setting connecting rod other end pin joint is pressed the string connecting rod, press the fulcrum pin of string connecting rod to be connected on string holder one side, the pressure string interlinking lever end of nearly fine setting connecting rod connects micromatic setting, press the other end of string connecting rod to be provided with pressure string pin, press and be rotary with the string nail on the string holder between string pin and the micromatic setting, each string nails at string around solid through separately pressure string pin and string holder one side separately, the string holder is rotated with on support through screw, the Handle axis of the modulation handle that is provided with is inserted in the axial hole of rotating shaft one end, the initial protuberance of the cam position difference of each scale string correspondence of the same range of sound in the rotating shaft, the initial protuberance of the cam position of each range of sound identical scale string correspondence is identical; The similarities and differences of the initial protuberance of cam position are by the determining positions of the groove that cooperates with key in the rotating shaft in the cam endoporus; The fine setting connecting rod is stepped, the roller of one end can touch cam, other end pin joint is on the fulcrum and the pressure string connecting rod between the micromatic setting of pressing the string connecting rod, press string connecting rod both ends all to be upturned, the middle part places in the groove of string holder one side, and the pressure string small end portion side direction that connects micromatic setting is towards the rectangular flange of fine setting connecting rod side; Micromatic setting is that the screw threads that is with spring is connected in the screw of pressing string connecting rod right angle flange, and the fine setting connecting rod is touched in the end of screw; Each string splits in the groove of string holder two sides with corresponding pressure string connecting rod; Press string pin vertical junction with the end of the pressure string connecting rod of string ipsilateral.

The ultimate principle that the utility model applied tension is changed voice, cam, fine setting connecting rod and pressure string connecting rod by each string correspondence are realized tension variation, guarantee that by micromatic setting is set the scale after the modulation is accurate, the utility model is adjusted to basic accent with A, can change successively D, G, C, F, ^bB transfers, and returns A and transfers, in performance, as long as the moving modulation handle modulation successively smoothly of plate is gently satisfied and played needs.
