Abstract
A thermoacoustic device includes a substrate, a first electrode and a second electrode, at least two supporting members, and a first carbon nanotube film. The substrate includes a surface. The first electrode and the second electrode are located on the surface of the substrate and spaced from each other. The at least two supporting members are spaced from each other and respectively located on surfaces of the first electrode and the second electrode. The at least two supporting members include a plurality of carbon nanotubes parallel with each other and substantially perpendicular to the surface of the substrate. The first carbon nanotube film is supported by the at least two supporting members and has a portion between the at least two supporting members suspended above the substrate. The supporting members electrically connect the first carbon nanotube film with the first electrode and the second electrode.
