Loudspeaker control system for intelligently adjusting volume

Abstract

The invention provides a loudspeaker control system for intelligently adjusting volume. The system comprises a wind pressure sensing control unit, which includes a differential amplification module, a reference voltage generation module and a wind pressure sensor module; an audio signal input unit; an audio signal processing unit, which includes a voltage controlled amplification module, a fixed gain amplification module, a power amplification module and a filter module; and a loudspeaker unit which is connected with an output end of the filter module. The device can automatically adjust the loudspeaker volume according to external wind power, and improve the listening experience of audiences.

Description

technical field [0001] The invention belongs to the field of loudspeaker control systems, and in particular relates to a loudspeaker control system for intelligent volume adjustment.
