THERMOACOUSTIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a thermoacoustic device which uses carbon nanotubes.

SOLUTION: The thermoacoustic device includes a signal device and a sound wave generator including a carbon nanotube structure. The carbon nanotube structure is connected to the signal device. The carbon nanotube structure includes at least one carbon nanotube film. Carbon nanotube films each include a plurality of carbon nanotubes having lengthwise ends connected together by intermolecular force. The heat capacity per unit area of the carbon nanotube structure is ≤2×10-4J/cm2.
