Abstract
The present disclosure relates to a method of producing sound waves. In the method, a carbon nanotube structure is provided. A signal is applied to the carbon nanotube structure and cause the carbon nanotube structure to produce heat. The heat is transferred to a medium in contact with the carbon nanotube structure to cause a thermoacoustic effect for producing sound waves.
