Electrical conductor of high magnetic permeability material for audio circuits

摘要

An improvement in the high frequency sound quality of audio circuits using copper electrical interconnections is realized by replacing copper electrical interconnections with interconnections of a material exhibiting a greatly reduced skin depth at audio frequencies. At the moment, without the availability of practical room-temperature superconductors, the most practical method is to use a material possessing a high magnetic permeability. By this means, phase dispersion due to the skin effect is virtually eliminated.
