<P>PROBLEM TO BE SOLVED: To provide a thermoacoustic device and a sound transmission system using the same, especially, a thermoacoustic device using carbon nanotubes and a sound transmission system using the same. <P>SOLUTION: The thermoacoustic device includes an electromagnetic signal device and a sound wave generator including a carbon nanotube structure. The electromagnetic signal device transmits an electromagnetic signal to the carbon nanotube structure. Alternatively, the thermoacoustic device includes the electromagnetic signal device and the sound wave generator including the carbon nanotube structure. The electromagnetic signal device transmits the electromagnetic signal to the carbon nanotube structure. The carbon nanotube structure transduces the electromagnetic signal into heat to make a medium generate thermoacoustic effect. <P>COPYRIGHT: (C)2010,JPO&INPIT |
