Abstract

The invention relates to a sound-producing device, which comprises an electromagnetic wave signal input device and a sound-producing element, wherein the sound-producing element comprises a carbon nanotube structure which contacts with a medium; and the electromagnetic wave signal input device transmits electromagnetic wave signals to the carbon nanotube structure, the carbon nanotube structure is heated by absorbing the electromagnetic wave signals, so that the medium is heated to produce sound waves. The invention also relates to the sound-producing element.

Description

technical field [0001] The invention relates to a sounding device and a sounding element, in particular to a sounding device and a sounding element based on carbon nanotubes. Background technique [0002] The sounding device generally consists of a signal input device and a sounding element. The electrical signal is input to the sound generating element through the signal input device, and then the sound is emitted. The sound emitting element in the prior art is generally a loudspeaker. The loudspeaker is an electro-acoustic device that converts electrical signals into sound signals. Specifically, the speaker can convert audio electric power signals within a certain range into audible sounds with less distortion and sufficient sound pressure level. There are many types of speakers. Although they work in different ways, they generally push the surrounding air by generating mechanical vibrations, causing the air medium to fluctuate so as to realize the conversion of "electr...
