Abstract:
A diaphragm includes carbon nanotube wire structures. The carbon nanotube wire structures are crossed with each other and woven together to form the diaphragm with a sheet structure. Each of the carbon nanotube wire structures includes carbon nanotube wires substantially parallel to each other, and closely arranged along an axis of the carbon nanotube wire structure to form a bundle-like structure, or carbon nanotube wires twisted with each other around an axis of the carbon nanotube wire structure in a helical manner to form a twisted structure. A loudspeaker using the diaphragm is also disclosed.
