Problems solved by technology

[0002] As a national musical instrument, the erhu has always maintained a traditional structure, but with the development of music, the demand for music performance is increasing, and the traditional erhu has been difficult to adapt to the rich and complex modern music.
In particular, for the impromptu solo in modern rock music, it is necessary to raise and lower the overall pitch in many places, and it is necessary to ensure the continuity and mellowness of the music. On the traditional erhu, the transfer can only be achieved by changing the handle as a whole. can not achieve

Embodiment 1

[0013] exist figure 1 In the first shown embodiment, the rock erhu includes a qin barrel 1, a qin bar 2, a qin head 3, a qin shaft 4, and strings 5; The piano bridge 11 attached to the piano skin of the piano tube 1 is fixed on the bottom of the piano tube 1;

[0014] Described piano bar 2 comprises lower half section 22, upper half section 21; Matching threaded rod 211. The threaded pipe 221 is axially connected to the lower half section 22 of the piano bar 2 through the basic bearing 7, the inner ring of the basic bearing 7 is fixed to the lower half section 22 of the piano bar, and the outer ring is connected to the second half section 22 of the piano bar. 221 is fixed; and, in the first embodiment, the outer diameter of the outer ring of the basic bearing 7 is equal to the outer diameter of the threaded pipe 221, which is not only beautiful, but also prevents the basic bearing 7 from causing obstacles to hand displacement; The outer periphery of the threaded pipe 221 is...

Embodiment 2

[0017] exist figure 2 , image 3 In the shown second embodiment, different from the first embodiment, the lower end surface of the basic bearing 7 is not higher than the lower end surface of the threaded pipe 221; An additional bearing 8 that can slide along the axially extending chute 220 that is formed on the surface of the piano bar 2, the additional bearing 8 is an elastic return bearing, and its structure is as follows: image 3 As shown, there is a return spring 83 surrounding the inner ring 81 between the inner ring 81 and the outer ring 82, and the two end legs of the spring 83 are fixed in the outer ring 82 so that the outer ring 82 rotates relative to the inner ring 81 , drive the return spring 83 to twist to form a reset force; when the external torque applied to the outer ring 82 contacts, the outer ring 82 can be reset under the action of the elastic reset force; the inner ring of the additional bearing 8 A slider matching the chute 220 is formed, and the upper...

Abstract

The invention provides a rock and roll erhu which comprises a canister, a bar, a head, a shaft and strings, wherein the strings wind the shaft, downwards crosses over a bridge on the canister and then is fixed at the lower part of the canister; the bar comprises a lower half section and an upper half section; the upper end of the lower half section is pivoted with a thread tube; a thread rod matched with the thread tube is arranged at the lower part of the upper half section. In the playing process, a player with the rock and roll erhu can continuously and freely key the whole strings up and down under a condition of not switching the holding position on the strings, so that the erhu is suitable for extemporaneous performance.

Description

technical field [0001] The invention relates to the field of musical instruments, in particular to an erhu. Background technique [0002] As a national musical instrument, the erhu has always maintained a traditional structure, but with the development of music, the demand for music performance has been increasing, and the traditional erhu has been difficult to adapt to the rich and complex modern music. In particular, for the impromptu solo in modern rock music, it is necessary to raise and lower the overall pitch in many places, and it is necessary to ensure the continuity and mellowness of the music. On the traditional erhu, the transfer can only be achieved by changing the handle as a whole. can not achieve. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a rock erhu, which can freely and continuously raise and lower the overall tone of the strings without switching the position during performance...
