Summary:PROBLEM TO BE SOLVED: To provide an earphone using carbon nanotubes. SOLUTION: The earphone includes at least one housing, and at least one sound wave generator disposed in the housing. The sound wave generator includes a carbon nanotube structure. The carbon nanotube structure includes a self-supporting structure. The thermal capacity per unit area of the carbon nanotube structure is ≤2×10-4J/(cm2K). COPYRIGHT: (C)2010,JPO&INPIT
