Patent ID: 7141740

Claim:
A sound signal wire, comprising: a first set of support wire units of N strands which forms a first space within the strands; a second set of support wire units of N strands which forms a second space within the strands; a first set of weaving wire units of 2N strands; a second set of weaving wire units of 2N strands; wherein: N is an integer equal to or greater than two; the first set of support wire units and the second set of support wire units are substantially disposed along a circumferential path and alternate with each other to serve as a support for the sound signal wire, and the first space overlaps the second space at a center portion thereof; the first set of weaving wire units rotationally, subsequently weave onto the first and second sets of support wire units along a lengthwise direction of the signal wire, which transversely follows a first path that is substantially a first closed loop formed around the first set of support wire units through the second space formed within the second set of support wire units; and the second set of weaving wire units rotationally, subsequently weave onto the first and second sets of support wire units along a lengthwise direction of the signal wire, which transversely follows a second path that is substantially a second closed loop formed around the second set of support wire units through the first space formed within the first set of support wire units.
