The explanation given by your source confuses these two phenomena.
Yes, audio equipment and cables support mechanical resonances, with frequencies in the audio band. This affects electrical performance through Faraday induction, and allows for performance improvement by ensuring adequate isolation and damping.
Electrical resonances exist in any segments of wiring terminated by mis-matched impedances. The relevant frequencies are in the VHF and higher radio bands and are completely inaudible to any living thing. However, electrical noise in the RF range can mix with the audio signal within audio equipment and create spurious audio-band artifacts.
Fuses may support both kinds of resonant behavior, as the elements can vibrate acoustically and the fuse holder represents an impedance change in the wiring path. I can see how a modified fuse design could help the acoustic behavior, but not how it would affect the electrical behavior.
