Description of the Invention: [Technical Field] [0001] The present invention relates to a sounding device, and more particularly to a sounding device based on a thermal sounding film. [Prior Art] [0002] A sounding device generally consists of a signal input device and a sounding element. The signal is input to the sounding component by the signal input device to emit a sound. The thermoacoustic device is one of the sounding devices, which is a sounding device based on the thermoacoustic effect, see the document "The Thermophone", EDWARDC. WENTE, Vol. XIX, No. 4, p333-345 & "On Some Thermal Effects of Electric Currents, ', William Henry Preece, Proceedings of the Royal Society of London, Vol. 30, pp 408-41 1 (1879-1881). This document discloses a thermo-acoustic device that A conductor is connected to an alternating current to achieve sound. [0003] HD Arno 1 d and IB Cranda 11 are described in the document "The therraophone as a precision source of sound", Phys. Rev. 10, p22-38 (191 7). A simple thermal sounding device adopts a platinum film as a thermal sounding film. Since the sounding frequency of the thermal sounding film is closely related to the heat capacity per unit area, the heat capacity per unit area is large, the sounding frequency range is narrow, and the intensity is low; The heat capacity is small, the sound frequency range is wide, and the intensity is high. To obtain sound waves with a wide sounding frequency range and high intensity, a single sounding component is required. The smaller the heat capacity of the bit area, the better. Due to the heat capacity per unit area of the material, the 09715182 production order number A〇101 page 4/30 pages 1013308316-0 1376679 101 years. August 14th, according to the replacement page The sounding device of the platinum sheet as a thermal sounding film has a sound frequency of up to 4 kHz, and the sounding frequency range of the sounding device is narrow. [0004] Since the early 1990s, carbon nanotubes have been used (see Helical) Microtubules of graphitic carbon, Nature, Sumio Iijiraa, vol 354, p56 (1991)) represent the unique structure and properties of nanomaterials that have attracted great attention. In recent years, along with carbon nanotubes and nai The research of rice materials continues to deepen, and its broad application prospects are constantly emerging. For example, due to the unique electromagnetic, optical, mechanical, and chemical properties of carbon nanotubes, a large number of electron sources and sensing signals are present in the field. Applications such as new optical materials, soft ferromagnetic materials, etc. have been reported.
