Abstract
A sound wave generator includes a carbon nanotube film. The carbon nanotube film comprises a plurality of carbon nanotubes entangled with each other. At least part of the carbon nanotube film is supported by a supporting element. The carbon nanotube film produces sound by means of the thermoacoustic effect.
Claims26
