Description of the Invention: [Technical Field] The present invention relates to a sound emitting device', and more particularly to a sound emitting device based on a carbon nanotube. [Prior Art] The sounding device is generally composed of a signal input device and a sounding element, and a signal is input to the sounding element by the signal input device to emit a sound. The thermoacoustic swell is a type of sounding device that is a sounding device based on thermoacoustic effects, ® HDArnold and LB.Cmndall in the literature "The thermophone as a precisi〇n source of sound", Phys. Rev. 10 A simple thermoacoustic device is described in p22-38 (1917) which uses a platinum sheet as the sounding element. Since the sounding frequency of the sounding element is related to the heat capacity per unit area, that is, the heat capacity per unit area is large, the sounding frequency range is narrow, and the sound wave intensity is low; when the heat capacity per unit area is small, the sounding frequency range is wide, and the sound wave intensity is still. Therefore, it is desirable to obtain a wide range of audible frequencies and a higher acoustic intensity. The metal sheet with a smaller heat capacity of 10 is limited by the material itself, and the thickness can be as small as Ο.μm, and the sounding device using the crystal sheet as the sounding element can produce the highest sounding frequency only. Up to 4 kHz. In addition, 'Yanshan et al. disclose the sounding device for making carbon nanotubes ^^^^Flexible > Stretchable ^ Transparent Carbon Nanotube Thin

The carbon nanotube structure includes a > 'a carbon nanotube film, at least a nano carbon line structure or a combination thereof. The thickness of the carbon nanotube structure (the diameter of the linear structure) is 05 nm to mm. Preferably, the carbon nanotube structure has a thickness of α 5 μm. The heat capacity may be less than (10), and the ear per square centimeter Kelvin.
