Description

A kind of piano bass string

Technical field

This utility model relates to piano technical field, is especially a kind of piano bass string.

Background technology

Piano bass string is arranged on piano sympathetic response dish, is used for playing.A piano of the applicant's earlier application at present Bass string, including overspun wire main body, described overspun wire main body includes core string and the winding silk being wrapped on core string, described winding Silk ring-wound is formed on core string annular clad, described overspun wire body end be wound around silk end be wrapped in core string and Between annular clad.The described end being wound around silk is wrapped in the shape on core string in the shape of a spiral.The described end being wound around silk Portion is wrapped in the number of turns on core string and is at least two circles.After the other end bending of this core string is wound around in twisted shape after buckleing, in crimped end It is wound around in Extension Spring-type.Although the most this structure solve vibrations that bass string in use produces and be wound around silk itself The reason of tension force, can make the winding silk being wrapped on core string produce loose, and make bass string produce Sha Muyin in performance, make sound Matter is impaired.But yet suffer from following shortcoming: owing to the core string of internal layer is round wire, i.e. circular in cross-section, such outer layer After winding, loose and cause Sha Muyin because being easily caused annular clad by the effect of tension force, thus affect the normal of piano and send out Sound.

Utility model content

The technical problems to be solved in the utility model is to provide one makes winding silk to be firmly wrapped on core string, keeps away Exempt from loose and produce the piano bass string of husky wood sound.

The technical solution of the utility model is to provide a kind of piano bass string with following structure, including overspun wire main body, Described overspun wire main body includes core string and the winding silk being wrapped on core string, and described winding silk ring-wound is formed on core string Annular clad, the end being wound around silk of described overspun wire body end is wrapped between core string and annular clad；Described core The afterbody twisted shape of string is formed around button at tail end after being wound around；Described core string is wound in this section of a ring-wound along its length It is provided with several grooves, between adjacent two grooves, is provided with interval.

Spacing between described adjacent grooves is equal.

The degree of depth of described groove is 1/2nd of core string radius.

The top side of described groove is equipped with fillet R.

After using above structure, this utility model has the advantage that owing to described core string is wound a ring-wound It is provided with several grooves in this section along its length, between adjacent two grooves, is provided with interval, so make the groove on core string have Limited location effect, is wound around after silk is wound around, can preferably be wrapped on core string, so when piano playing, it is to avoid loose and produce Sha Muyin.

As improvement, the spacing between described adjacent grooves is equal, makes more uniform.

As improvement, the top side of described groove is equipped with fillet R, thus is avoided that scuffing is wound around silk.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, Figure 2 and Figure 3, piano bass string of the present utility model, including overspun wire main body, described overspun wire main body Including core string 1 and the winding silk 2 being wrapped on core string 1, described core string 1 generally piano wire, piano wire has high resisting Zhang Qiangdu and preferable plasticity, and circularity is good, the change of line footpath is little, described winding silk 2 generally copper cash, described winding silk 2 Ring-wound forms annular clad 2.1 on core string 1, and the end 2.2 being wound around silk 2 of described overspun wire main body section start 3 twines It is wound between core string 1 and annular clad 2.1, the end 2.2 being wound around silk 2 is wrapped in core string 1 and is wound around between silk 2, not only The free end being wound around silk 2 it is fixed on core string 1 and is wound around between silk 2, and carrying by being wound around the end 2.2 extruding winding silk 2 of silk 2 The high intermolecular forces being wound around silk 2 and core string 1, makes to combine between winding silk 2 and core string 1 more stable, reduces being wound around silk 2 and produce Loose possibility, makes bass string not send Sha Muyin in performance, and can be close at overspun wire main body section start by being wound around silk 2 Destination county side is wound around toward section start, reversely starts ring-wound and arrives overspun wire main body destination county, complete to twine after arriving section start Around.Described core string is wound in this section of silk 2 ring-wound and is provided with several grooves 1.1 along its length, adjacent two grooves Interval it is provided with between 1.1.These several grooves 1,1 use Sheet Metal Forming Technology to make zigzag structure.

Spacing between described adjacent grooves 1.1 is equal, is wound around silk 2 and is wrapped in more uniformly on core string 1.

The degree of depth of described groove is 1/2nd of core string 1 radius, the most both can guarantee that winding effect, and also can guarantee that core string The intensity of 1.

The top side of described groove 1.1 is equipped with fillet R, after punch process, uses polishing mode, forms fillet.
