Abstract

The invention discloses a long-service-life Chinese lute string. The Chinese lute string is of a laminated composite structure, an inner core of the laminated composite structure is a steel wire, an intermediate layer is coated on the outer surface of the inner core, and a nylon outer layer is arranged on the outer surface of the intermediate layer; a coating is arranged on the outer surface of the steel wire inner core, and the coating is a metal ceramic composite coating; the intermediate layer is a copper-based alloy layer; and the inner core of the laminated composite structure is a steel wire twisted rope formed by combining a single steel wire or a plurality of steel wires. The coating is arranged to ensure that the strength and elastic modulus of the inner core can be effectively increased, so that the fatigue damage resistance of the inner core can be improved, and original cracks on the surface of the inner core can be prevented from being further expanded to cause breakage under the condition that the Chinese lute string is played repeatedly for a plurality of times for a long term; and meanwhile, because components of the coating comprise both metals and ceramics, the playing tone of the Chinese lute string disclosed by the invention has the characteristic of bright metal sound, and also has the characteristic of relatively mild and soothing sound produced by the 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...
