Abstract
A sound wave generator includes one or more carbon nanotube film. The carbon nanotube film includes a plurality of carbon nanotubes joined end to end by van der Waals attractive force therebetween. At least part of the one or more carbon nanotube film is supported by a supporting element. The one or more carbon nanotube film produces sound by means of the thermoacoustic effect.
