Abstract

The invention relates to a sound transmission system, which comprises an acoustoelectric conversion device for converting sound signals to electrical signals; an electric wave conversion device which is electrically connected with the acoustoelectric conversion device and converts the electrical signals produced by the acoustoelectric conversion device to electromagnetic signals; and a sounding component, wherein the sounding component comprises a carbon nanotube structure which contacts with a medium, the electric wave conversion device transmits electromagnetic signals to the carbon nanatube structure which is heated through absorbing the electromagnetic signals, thereby heating the medium to send out sound wave.

Description

technical field [0001] The invention relates to a sound transmission system, in particular to a sound transmission system based on carbon nanotubes. Background technique [0002] The sound transmission system includes two types: wired sound transmission system and wireless sound transmission system. A traditional wired sound transmission system generally consists of an acoustic-to-electric conversion device, a power transmission line and an electro-acoustic conversion device. The acoustic-electric conversion device is generally a microphone or a microphone, and the electro-acoustic conversion device is generally an earpiece, speaker or earphone. The sound-to-electric conversion device converts the sound into an electric signal, and transmits the electric signal to the electro-acoustic conversion device through the power transmission line, and the electro-acoustic conversion device restores the electric signal to a sound signal. However, due to the limitation of power trans...
