A thermoacoustic device includes a substrate, at least two sound wave generators and at least two signal input devices. The substrate has at least two surfaces. Each of the at least two sound wave generators is located on each of the at least two surfaces. At least one of the at least two sound wave generator includes a carbon film. The carbon film includes at least one carbon nanotube layer and at least one graphene layer stacked with each other. The at least two signal input devices are configured to input signals to the at least two sound wave generator in a one by one manner.
