Referring to Fig. 1, the production method of the Sound cable includes step S101 to S104.
Four S101, production first conductive core lines.
Specifically, each first conductive core line include include the first conductor and be coated on outside the first conductor first
Insulating layer.First conductor is metallic conductor, and for example, by using conductor made of copper or aluminium etc., which is flexiplast
(TPE, Thermop lastic Elastomer) insulating layer, TPE insulating layer can not only guarantee that insulation effect was good, but also can drop
The thickness of the low insulating layer reduces extruding of the bending front and back plastic shrink to the first conductor, and then increases the anti-of Sound cable
Pulling force.
More specifically, the first insulating layer is using structure made from modified PE material, and using first made of PVC material
Insulating layer is compared, since the polarization of PE interior molecules is weaker than the polarization of PVC interior molecules, thus using first made of modified PE material

Dynamic unwrapping wire mode, guarantees each strand even tension of the first intermediate core wire, to improve the energy of Sound cable bending and tension
Power.
The intermediate core wire of the second of the Sound cable be twisted using four second conductive core lines and be made, i.e., using extremely
The mode that few two copper wire elder generation bundle strands close strand again is made, while being all made of active unwrapping wire mode when closing and twisting, and guarantees this in second
Between core wire each strand even tension, thus further increase Sound cable bending and tension ability.
The combination core wire of the Sound cable is by the way that a first intermediate core wire and a second intermediate core wire to be twisted
It is made, while using active unwrapping wire mode when twisted, guarantee each strand even tension of the combination core wire, to further mention
The ability of high sound equipment cable folding and tension.
