Problems solved by technology

However, some people think that it is troublesome to buy tickets for such occasions, and it is inconvenient to be crowded. In order to reduce economic expenses and achieve real pressure relief, some people instead set up sounding devices at their own homes or rent a place to hold parties.
[0003] However, due to environmental influences, traditional speakers cannot automatically adjust the volume according to the wind, which will cause the volume of the sound heard by the listener to fluctuate, affecting the listening experience of the audience

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. Background technique [0002] Nowadays, with the development of society, people are under more and more pressure, and the communication and interaction between people are gradually less. In order to relieve the pressure in life, many people begin to work or When it's a holiday, you will want to find some ways to decompress, and the methods are nothing more than going out for a walk or watching a movie. But these lack the interaction between people, so more and more people like to go to concerts or musicals to relieve the pressure accumulated on weekdays. However, some people think that it is troublesome to buy tickets for such occasions, and it is inconvenient to be crowded. In order to reduce economic expenses and achieve real pressure relief, some people instead set up sound-generating device...
