Plasma sound box

Abstract

The invention discloses a plasma sound box, which comprises a pulse width modulation module, a power output module, a power supply module and an expansion module, wherein the expansion module outputsaudio signals and is connected with the input terminal of the pulse width modulation module, the output terminal of the pulse width modulation module is connected with the input terminal of the poweroutput module, and the power supply module is a three terminal-integrated voltage regulator 7805 and provides power for the pulse modulation module, the power output module and the expansion module.

Description

technical field [0001] The invention relates to the technical field of plasma audio, in particular to a plasma audio. Background technique [0002] At present, the existing traditional mechanical speakers generally cause the vibration of the diaphragm to cause air vibration to produce sound, but the diaphragm has a certain quality, which leads to distortion of the sound effect. It cannot meet the needs of most music lovers and special people. Therefore, some audio systems use linear power amplification for the audio signal to make the voltage level of the audio signal reach the kilovolt level, and this voltage is directly loaded on the electrode, and then the electrode is driven to discharge, and the arc disturbs the air to form a sound wave. However, the implementation of this kind of plasma sound is relatively complicated, and at the same time, amplifying the audio signal to the level of kilovolts and maintaining the linearity of the signal requires a high level of techno...
