Structure of speaker signal line

Abstract

A structure of a speaker signal line having a middle filler layer, a plurality of transmission conductors and an outer coating portion, wherein, the middle filler layer is comprised of many hollow tubes. The transmission conductors are equidistantly spaced and wrapped over the middle filler layer. The coating portion is made of polyvinyl chloride composition. The middle filler lay is formed in the way of entangling to increase its strength and flexibility. The transmission conductors are spaced mutually in different layers and wrapped over the middle filler layer in mutual contrary directions. All the elements above are combined together by adding the outer coating portion, thereby, the inductive resistance induced by the transmission conductors equidistantly spaced in different layers and wrapped in mutual contrary directions can be mutually offset.
