Beschreibung
Zusammenfassung:	An acoustic system includes a sound-electro converting device, a electro-wave converting device, and a sound wave generator. The electro-wave converting device is connected to the sound-electro converting device. The sound wave generator is spaced from the electro-wave converting device and includes a carbon nanotube structure. The sound-electro converting device converts a sound pressure to an electrical signal and transmits the electrical signal to the electro-wave converting device. The electro-wave converting device emits an electromagnetic signal corresponding to the electrical signal and transmits the electromagnetic signal to the carbon nanotube structure. The carbon nanotube structure converts the electromagnetic signal into heat, and the heat transfers to a medium causing a thermoacoustic effect.
