Abstract
An apparatus includes an electromagnetic signal device, a medium, and a sound wave generator. The sound wave generator includes a carbon nanotube structure. The carbon nanotube structure includes one or more carbon nanotube films. Each carbon nanotube film includes a plurality of carbon nanotubes entangled with each other. The electromagnetic signal device transmits an electromagnetic signal to the carbon nanotube structure. The carbon nanotube structure converts the electromagnetic signal into heat. The heat transfers to the medium and causes a thermoacoustic effect.
