Abstract

The utility model discloses a kind of piano bass strings, it include the overspun wire ontology being made of core string and winding silk, the winding silk ring-wound forms annular package outer layer on core string, it is formed in tail end around buckleing after the tail portion twisted shape winding of the core string, and the tail end end of core string is wound around on core string ontology, forming fried dough twist after the tail portion twisted shape winding of the core string winds section；It is characterized in that：One section that silk winding is wound on the core string is equipped with the one or more of raised lines or groove being wrapped on core string.The bass string increases the frictional force between winding silk and core string, keeps the effect around string preferable, avoids loosening and generating husky sound.

Description

Piano bass string

Technical field

The utility model is related to piano technical fields, are especially a kind of piano bass string.

Background technology

A kind of piano bass string, including overspun wire main body are disclosed at present, and the overspun wire main body includes core string and is wrapped in Winding silk on core string, the winding silk ring-wound form annular clad, the overspun wire body end on core string The end of winding silk be wrapped between core string and annular clad；It is formed in tail end after the tail portion twisted shape winding of the core string Around button；End after the core string winding is flushed with the lateral wall of the winding section.The piano bass string of the above this structure exists Following disadvantage：Due to winding silk ring-wound on core string after, it is long-term beaten pronunciation after, be easy to cause winding silk pine Dynamic, to cause piano to generate husky sound when playing, the frictional force that the main reason for generation is wound around between silk and core string is insufficient, Keep the effect around string poor.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of frictional force increased between winding silk and core string, makes Effect around string is preferable, avoids the piano bass string for loosening and generating husky sound.

The technical solution of the utility model is to provide a kind of piano bass string having following structure, including by core string and The overspun wire ontology of silk composition is wound, the winding silk ring-wound forms annular package outer layer on core string, the core string It is formed around button in tail end after the twisted shape winding of tail portion, and the tail end end of core string is wound around on core string ontology, the core string The winding of tail portion twisted shape after form fried dough twist and wind section；One section that silk winding is wound on the core string is equipped with one or more Item is wrapped in raised line or groove on core string.

The quantity of the raised line is one, and the height of raised line is 0.3~0.5mm, and the raised line is wrapped between core string Away from being equal.

The quantity of the groove is one, and the depth of groove is 0.3~0.5mm, and the groove is wrapped between core string Away from being equal.

The core string is equipped with a raised line and a groove, and the two parallel equidistant is wound.

After using the above structure, the utility model has the following advantages：Due to being wound the one of silk winding on the core string Section is equipped with the one or more of raised lines or groove being wrapped on core string, and the outer wall of winding silk can be made to be embedded in opening for groove To carry out axial limiting to winding silk in mouthful；Or the outer wall of the winding silk after winding be mutually against raised line outer wall it is outer thus Axial limiting is carried out to winding silk, both the above mode can increase the frictional force between wrapping wire and core string, make the effect around string Preferably, it avoids loosening and generating husky sound.

As shown in the figure：

1, core string, 1.1, raised line, 1.2, groove, 2, winding silk, 3, around button, 4, fried dough twist wind section,

Specific implementation mode

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

As shown in Figs 1-4, the piano bass string of the utility model includes the overspun wire sheet being made of core string 1 and winding silk 2 Body, 2 ring-wound of winding silk forms annular package outer layer on core string 1, after the tail portion twisted shape winding of the core string 1 It is formed around button 3 in tail end, and the tail end end of core string 1 is wound around on 1 ontology of core string, the tail portion twisted shape of the core string 1 Fried dough twist is formed after winding winds section 4；One section that the winding of silk 2 is wound on the core string 1 is equipped with one or more of be wrapped in Raised line 1.1 on core string 1 or groove 1.2.

The quantity of the raised line 1.1 is one, and the height of raised line 1.2 is 0.3~0.5mm, and the raised line 1.1 is wrapped in The spacing of core string 1 is equal, and the outer wall of the winding silk 2 after winding is mutually against outside the outer wall of raised line 1.1 to winding silk 2 Axial limiting is carried out,

The quantity of the groove 1.2 is one, and the depth of groove 1.2 is 0.3~0.5mm, and the groove 1.2 is wrapped in The spacing of core string 1 is equal, the outer wall of winding silk 2 can be made to be embedded in the opening of groove 1.2 to carry out axis to winding silk 2 To limit.

The core string 1 is equipped with a raised line 1.1 and a groove 1.2, and the two parallel equidistant is wound, and winds in this way The outer wall of winding silk 2 afterwards is mutually against other 2 outer wall of winding silk adjacent simultaneously outside the outer wall of raised line 1.1 and is embedded in groove In 1.2 opening, to carry out axial limiting to winding silk 2, winding effect is greatly increased.
