Abstract
A thermoacoustic device includes a substrate, at least one first electrode, at least one second electrode and a sound wave generator. The at least one first electrode and the at least one second electrode are disposed on the substrate. The sound wave generator is contacting with the at least one first electrode and the at least one second electrode. The sound wave generator is suspended on the substrate via the first electrode and the second electrode. The sound wave generator includes a carbon nanotube structure.
