    • PURPOSE: A sound emitting device is provided to emit a sound wave through expansion and compression of surrounding air by using temperate change of a carbon nanotube. CONSTITUTION: A sound emitting device is composed of a signal input device(12), a sound generation element(14), a first electrode(142), and a second electrode(144). The first electrode and the second electrode are installed at both ends of the sound generation element. The first electrode and the second electrode are electrically connected to the both ends of a signal input device. A signal from the signal input device is inputted through the first electrode and the second electrode to the sound generation element. The signal includes one or more than one of electromagnetic wave, alternating current, an audio electric signal, and an optical signal. The sound generation element includes the carbon nanotube structure.
