Description

Technical Field

[0001] This utility model relates to the field of musical instrument processing technology, specifically a musical instrument string. Background Technology

[0002] Strings are an important component of plucked string instruments such as the guzheng and guitar, and the quality of the strings directly affects the quality of the instrument to a certain extent.

[0003] Existing strings generally consist of a core and a winding layer. The winding layer is typically made up of one or two specific winding threads tightly wound around the outside of the core in a spiral manner. While this spiral winding method does not significantly improve the tensile strength of the string, it can lead to string breakage when subjected to significant plucking, thus affecting the normal use of the instrument. Furthermore, the cross-section of the winding threads is generally circular and the material is relatively hard, resulting in an uneven string surface after spiral winding. Even with the application of string glue, the friction and pain to the fingers are still significant in the initial stages of use, reducing the comfort of playing the string. Utility Model Content

[0004] The purpose of this invention is to provide a string in which the braided layer and the string core can simultaneously withstand axial tension, thereby greatly improving the tensile strength of the string and making it less prone to string breakage during use. Furthermore, the braided layer can be tightly woven, resulting in a smoother surface of the string after weaving, thus improving the comfort of using the string.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a string, including a string core, and at least one braided layer wrapped around the outside of the string core.

[0006] Preferably, the string includes glue, which is used to fix the braided layer to the string core.

[0007] Preferably, the core is made of metal, nylon, or silk.

[0008] Preferably, the braided layer comprises a silk bundle, wherein the silk bundle comprises at least one silk thread.

[0009] Preferably, four layers of braided fabric are wrapped around the outer side of the string core from the inside out.

[0010] Furthermore, the two adjacent braided layers are bonded together using silk glue or string glue, and the braided layer that is in contact with the string core is also bonded together using silk glue or string glue.

[0011] Furthermore, a layer of string glue or silk glue is coated on the outside of the strings.

[0012] Preferably, the woven layer has a plain weave.

[0013] Preferably, the outer side of the string core is wrapped with seven layers of the braided layer from the inside to the outside.

[0014] The beneficial effects of this utility model are: the utility model has a simple structure and is convenient to process and manufacture; the braided layer is wrapped around the outside of the string core, and when the string is tightened, the braided layer and the string core can resist the tension synchronously, thereby improving the tensile strength of the string to a certain extent. At the same time, when the braided layer has multiple layers, the tensile strength of the string can be further improved; the braided layer can achieve a relatively tight weave, so after the braided layer is completed, the surface of the string is relatively smooth, thereby reducing the friction pain when using the string, and thus improving the comfort of using the string.

[0018] The following will describe specific embodiments and appendices. Figure 1 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] This utility model provides a string (such as...) Figure 1The instrument (described above) includes a string core 1, with at least one braided layer wrapped around its outer surface. In practical applications, the braided layer and the string core 1 form a single string. When the string is tensioned, the braided layer and the string core 1 are simultaneously subjected to axial tension. Because the braided layer is woven, it possesses strong tensile strength, which in turn gives the string strong tensile strength, preventing it from easily breaking during use and ensuring the instrument's usability. When the braided layer is multi-layered, the string's tensile strength is further enhanced. Furthermore, when the braided layer uses relatively soft fiber materials and is tightly woven, the surface of the braided layer becomes smoother, improving the string's comfort. To further improve string comfort, a layer of string glue or silk glue can be applied to the outer surface of the string.

[0020] In practical applications, to further improve the stability of the braided layer wrapping around the string core 1, the string also includes glue. The glue is used to fix the braided layer and the string core 1. Specifically, after the braiding of the layer is completed, glue can be applied to the braided layer. The glue penetrates between the braided layer and the string core 1. After the glue solidifies, the braided layer and the string core 1 are fixedly connected. In this specific embodiment, the glue can be: leather glue, bone glue, fish glue, PVA glue, CA glue, or EPOXY epoxy resin glue.

[0021] In practical applications, the material of the string core 1 can be metal, nylon, or silk. When the material of the string core 1 is metal, it can be steel wire.

[0022] In the actual processing of the strings, in order to smoothly weave the braided layer and at the same time ensure the sound quality of the strings, the braided layer includes a silk bundle 25, which includes at least one silk thread. In this specific embodiment, the silk bundle 25 includes one silk thread. The weaving parameters of the braided layer using the silk bundle 25 can be set according to the existing weaving process.

[0023] Based on the above embodiments, to ensure the tensile strength and comfort of the strings, four braided layers are sequentially wrapped around the outer side of the string core 1 from the inside out. Specifically, these are the first braided layer 21, the second braided layer 22, the third braided layer 23, and the fourth braided layer 24. To facilitate the tight connection of the four braided layers and the tight connection between the first braided layer 21 and the string core 1, adjacent braided layers are bonded together using silk glue or string glue. The braided layer that is bonded to the string core 1 (i.e., the first braided layer 21) is bonded together using silk glue or string glue. Since silk is relatively soft, the braided layers can be densely woven using silk bundles, resulting in a smoother surface and improved string comfort. To further improve string comfort, a layer of string glue or silk glue can be applied to the outer side of the string (i.e., the outer side of the fourth braided layer 24).

[0024] In the actual weaving process of the braided layer, in order to facilitate the control of the surface smoothness of the braided layer through the weaving process, the braided layer can be made into a plain weave structure.

[0025] In practical applications, in order to further improve the tensile strength of the strings, seven woven layers can be sequentially included from the inside to the outside of the string core 1 during the manufacturing process.

[0026] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

[0027] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. For those skilled in the art, several improvements and modifications can be made without departing from the concept of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
