Polished string

Abstract

The ground and polished string comprises a wire core and a winding wire spirally wound outside the wire core, the surface, in contact with the wire core, of the winding wire is an arc surface, and the surface, away from the wire core, of the winding wire is a plane. The surface, far away from the wire core, of the winding wire is the surface layer of the string, and the surface layer is flattened, so that the surface layer of the string is flat and smooth, damping feeling can be reduced, rapid sliding of fingers of a player in the playing process is facilitated, and the player is not prone to fatigue after playing for a long time. In addition, after the appearance is polished, the tone of the string is warm, and the tone of the string can be kept unchanged for a long time.

Description

Technical Field

[0001] The utility model relates to musical instrument accessories, in particular to a polished musical instrument string. Background Art

[0002] like Figure 1 As shown, a string generally includes a core 2 and a winding 1 spirally wound around the core 2. For example, a string and a manufacturing method thereof with Chinese Patent Publication No. CN110517651A include a core and a winding wound around the core, wherein the winding includes a copper wire, a silver-plated layer covering the surface of the copper wire, and a protective layer covering the silver-plated layer, wherein the protective layer is a mixture of paint and metal powder. The cross-sectional area of ​​the winding is a standard circle, so the spacing between adjacent spiral nodes is large, so the surface resistance of the string is large, which affects the rapid sliding of the player's fingers and makes the player easily fatigued. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a polished string, which reduces the damping feeling on the surface of the string, is conducive to the rapid sliding of the finger of the player, and the player is not easily fatigued after playing for a long time.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a polished string, including a wire core and a winding wire spirally wound outside the wire core, the side of the winding wire in contact with the wire core is a circular arc surface, and the side of the winding wire away from the wire core is a flat surface. The side of the winding wire away from the wire core is the surface layer of the string, and the surface layer is flattened to make the surface layer of the string flat and smooth, which can reduce the damping feeling, facilitate the rapid sliding of the fingers of the performer during the performance, and make the performer less tired during long-term performance; in addition, after the appearance is polished, the tone of the string is warm, and the tone of the string can be kept unchanged for a long time.

[0005] As an improvement, the flat surface is formed by cutting or grinding.

[0006] As an improvement, the distance between the middle point of the outer side surface of the winding and the center of the winding is smaller than the distance between the middle point of the inner side surface of the winding and the center of the winding.

[0007] As an improvement, the cross section of the winding wire is in the shape of a circular segment.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] The side of the wound wire away from the core is the surface of the string. Flattening the surface makes the surface of the string smooth and flat, which can reduce the damping feeling, facilitate the rapid sliding of the player's fingers during the performance, and make the player less prone to fatigue during long-term performance. In addition, after the appearance is polished, the tone of this kind of string is warm, and the tone of the string can remain unchanged for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] like Figures 2 to 4 As shown, a polished string comprises a core 2 and a winding wire 1 spirally wound around the core 2. The winding wire 1 is a copper wire; the side of the winding wire 1 in contact with the core 2 is an unprocessed arc surface 12, and the side of the winding wire 1 away from the core 2 is a processed plane 11, the cross section of the winding wire 1 is a circular segment, and the distance D1 from the middle point of the outer side surface of the winding wire 1 to the center of the winding wire 1 is less than the distance D2 from the middle point of the inner side surface of the winding wire 1 to the center of the winding wire 1; the plane 11 is formed by cutting or grinding. The side of the winding wire 1 away from the core 2 is the surface layer of the string, and the surface layer is flattened to make the surface layer of the string flat and smooth, which can reduce the damping feeling, facilitate the rapid sliding of the fingers of the performer during the performance, and make the performer less tired after long-term performance; in addition, after the appearance is polished, the tone of this string is warm, and the tone of the string can remain unchanged for a long time.
