Description

technical field

[0001] The invention relates to a sounding device, in particular to a sounding device 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.

[0003] There are many kinds of existing loudspeakers, which can be divided into electrodynamic loudspeakers, electromagnetic loudspeakers, electrostatic loudspeakers and piezoelectric loudspeakers according to their working principles. Although they work in different wa...
