Problems solved by technology

Most of the existing lute strings are made of a single steel wire rope or a steel wire rope compounded with a nylon rope on the outer layer. Because the lute strings are subjected to repeated external forces for a long time during the playing process, they are prone to fatigue damage and breakage, and the service life is short. convenient

Abstract

The invention discloses a long-life lute string. The lute string has a layered composite structure. The inner core of the layered composite structure is steel wire. The outer layer; the outer surface of the inner core of the steel wire is provided with a coating, the coating is a cermet composite coating; the middle layer is a copper-based alloy layer; the inner core of the layered composite structure is formed by a single steel wire or multiple steel wires Steel twisted rope. The setting of the coating can effectively improve the strength and elastic modulus of the inner core, thereby improving the ability of the inner core to resist fatigue damage, and preventing the original cracks on the surface of the inner core from further expanding under the condition of repeated playing for a long time. At the same time, because the coating composition contains both metal and ceramics, the timbre played by the pipa strings not only has the bright characteristics of metal sounds, but also has the relatively mild and soothing characteristics brought by ceramics.

Description

technical field [0001] The invention relates to a part for playing a musical instrument, in particular to a long-life lute string. Background technique [0002] Pipa, a stringed plucked string instrument, was born around AD. Pipa is made up of components such as string heads, backboards, panels, pegs, phases, frets, binding strings and strings. The strings of the pipa are the sound source of the pipa. The player plays the strings with both hands and ten fingers to make the strings vibrate, thereby emitting sounds of different frequencies. the sound of. [0003] Although strings do not account for an important proportion of pipa in terms of value, pipa strings play a vital role in the pronunciation of pipa. The quality of strings and the matching between strings and pipa itself are related to the performance of the entire pipa. . Therefore, in recent years, pipa players and manufacturers, while vigorously carrying out pipa reforms, are also constantly exploring the best m...
