Title:
THERMOACOUSTIC DEVICE
Document Type and Number:
Japanese Patent JP2010136368
Kind Code:
A
Abstract:
To provide a thermoacoustic device, specifically, the thermoacoustic device utilizing a carbon nanotube.
This device includes: a signal device; and a sound wave generator including a carbon nanotube structure. At least a part of the carbon nanotube structure contacts a liquid medium. The carbon nanotube structure converts a signal from the signal device into heat. The density of the liquid medium is converted to generate sounds. The heat capacity of the carbon nanotube structure per unit area is 0 (not including 0) to 2×10
