Abstract
Implementations of audio cables including a conductor spirally wrapped in a non-conductive thread to centrally position the conductor within a channel comprising mostly air include a first conductor having a first diameter, and a non-conductive thread spirally wrapped around the center conductor, the non-conductive thread having a second diameter. A first jacket surrounds the center conductor and thread, having an inner diameter approximately equal to the first diameter plus twice the second diameter. A second conductor surrounds the first jacket and/or the center conductor and thread. In many implementations, the first diameter is less than the second diameter.
Claims12
An audio cable, comprising:
- a first conductor having a first diameter;
- a non-conductive thread spirally wrapped around the first conductor having a second diameter;
- a first jacket surrounding the first conductor and thread, having an inner diameter approximately equal to the first diameter plus twice the second diameter;
- and
- a second conductor contacting the first jacket;
- and
- a channel formed by an inner surface of the first jacket;
- wherein a sum of the cross-sectional areas of the first conductor and thread is equal to less than 30% of a cross-sectional area of the channel.
