Abstract
The present disclosure relates to a voice coil lead wire and a loudspeaker using the same. The voice coil lead wire includes a lead wire structure and a core wire structure. The lead wire structure includes at least one lead wire. The core wire structure includes at least one carbon nanotube wire structure. The carbon nanotube wire structure includes a plurality of carbon nanotubes. The at least one lead wire winds around the at least one carbon nanotube wire structure in a helix manner or a twisted manner.
