Abstract:
A coaxial audio cable of the invention is design to separate audio signal into high and low pitch, e. g. , for BASS and TREBLE. This is achieved by using two or more different AWG conductors for inner and outer conductive layers. The inner and outer layers of conductors may have different number of wires and are twisted at different angles to match specific operation conditions of the conductors that fulfill different functions. In addition to insulation layers made from Teflon or a similar plastic, the conductive layers that fulfill different functions can be shielded with a metal foil for additional protection against signal interference. The foil may be placed between the inner layer and the outer layer, and additionally over the outer layers, or only around the outer layer. The conductor wires are insulated from each other by being embedded and sealed in a cured insulating coating such as a curable resin. Another distinguishing feature of the cable of the invention is that the conductor wires are twisted with a relatively low angle, which for the inner layer is within the range from 0 to 18 degrees and for the outer layer is from 8 to 12 degrees.
