▎ 摘　　要

NOVELTY - The thermoacoustic device has a sound wave generator (102) that is provided with a carbon film. The carbon nanotube layer and graphene layer are stacked on each other. A signal input device is provided to input signals to the sound wave generator. USE - Thermoacoustic device. ADVANTAGE - The sound effect and efficiency of the thermoacoustic device can be increased, by increasing the mechanical strength and toughness of carbon nanotube film and by reducing the coefficient of friction of the carbon nano film. The driving voltage of the thermoacoustic device can be decreased. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the thermoacoustic device. Sound wave generator (102) Electrodes of signal input device (104a,104b) Substrate (208) Recess of substrate (208a)
