Voice coil material -Nomex of paper(NSV)

Asbestos is a heat resistant material that does not conduct electricity or magnetism, and has a lower cost. It is a good material for making sound coil frames for alarms, small caliber (3.5 inches or 5 inches), or bass speakers. It has the following characteristics:(1) The surface is smooth and smooth.(2) It is non-conductive and will not generate magnetic field electrical current (votex) insideSurface smoothness and smoothness: The smoothness and smoothness of the surface is an important indicator for evaluating the quality of voice coils.It is non-conductive and does not generate magnetic field electrical flow inside: The metal voice coil skeleton will generate flow, which consumes some energy, reduces the efficiency of the speaker, and affects the magnetic field in the magnetic gap, reducing the effective frequency range of the speaker. Asbestos is not a conductor, and can prevent the adverse effects of flow.

Temperature resistance from 200 ° C to 220 ° C
