Full-spring-framework fine adjustment looping cord of erhu

Abstract

The invention belongs to the erhu manufacturing field, particularly relates to a full-spring-framework fine adjustment looping cord of an erhu. The erhu full-spring-framework fine adjustment looping cord comprises a spring fine adjustment framework A (15) and a spring fine adjustment framework B (16), which are components of same specification, same shape and same structure. Each spring fine adjustment framework is formed by winding a stainless steel wire continuously, and comprises a spring framework upper sleeve spring (9), a pressure spring (10), a spring framework lower sleeve spring (11), a spring framework limiting gear (12), a spring framework right hoop (13) and a spring framework left hoop (14); fine adjustment nut posts (8) are installed in the spring framework upper sleeve spring (9) and the spring framework lower sleeve spring (11) of each spring fine adjustment framework A (15), as well as in the spring framework upper sleeve spring (9) and the spring framework lower sleeve spring (11) of each spring fine adjustment framework B (16), so as to connect each spring fine adjustment framework A (15) and the corresponding spring fine adjustment framework B (16) into an integral fine adjustment framework; and the fine adjustment frameworks are hooped at appropriate positions of a neck (1) through the spring framework right hoops (13) and a spring framework left hoops (14). The full-spring-framework fine adjustment looping cord has the advantages of being ingenious in design, novel and unique, smooth in hand feeling and simple in operation.

Description

technical field [0001] The invention belongs to the field of musical instrument systems, in particular to an erhu full-spring structure fine-tuning jack. Background technique [0002] The production process of erhu has always followed the original and backward manual method of the workshop. The key reason is that there is no in-depth research and development on the production process. The erhu is a uniquely attractive stringed national musical instrument. Its timbre is close to the human voice, and it has a high emotional rendering power. However, the structure of the erhu is simple, and the production method is relatively extensive, so it will bring some inconvenience when playing. A series of troubles. The erhu full-spring structure fine-tuning jack is a kind of erhu jack with simple structure and rich functions, which uses discrete fine-tuning to erhu scale calibration, oscillating string length limitation and quick transfer. At the same time, it brings convenience to ...
