Abstract
A loudspeaker includes a magnetic system defining a magnetic gap, a vibrating system, and a supporting system. The vibrating system includes a diaphragm, a voice coil bobbin disposed in the magnetic gap, a coil lead wire having a first end and a second end, and a voice coil wound around the voice coil bobbin and electrically connected to the first end. The supporting system includes a frame fixed to the magnetic system and receiving the vibrating system. The frame has a terminal electrically connected to the second end of the coil lead wire. The diaphragm is received in the frame. The voice lead wire includes at least one carbon nanotube wire structure. The carbon nanotube wire structure includes a plurality of carbon nanotubes.
