Abstract

The invention discloses a volume control system, comprising a communication network access end and a display device connected with the network access end. A signal sensing module, a control chip connected with the signal sensing module and a loudspeaker connected with the control chip are set in the display device. The signal sensing module is connected with the network access end to continuouslysense signal change of the network access end, and transmits a signal to the control signal. The control chip sends out a control signal to control the loudspeaker to work.

Description

technical field [0001] The invention relates to a control system, in particular to a volume control system. Background technique [0002] The volume of common video playback devices, such as TVs, computer monitors, etc., usually needs to be manually controlled to meet different playback environments. [0003] However, in a common living environment, if people watch and play videos through video playback equipment, if they need to answer incoming calls from communication equipment such as mobile phones, then in order to ensure that the communication is clear and smooth without being disturbed, it is necessary to manually adjust the control device. The volume of the video playback device, turn down the volume or mute it, and when the power connection is over, adjust the volume again. In this way, the volume control operation of the video playback device is relatively cumbersome. With the increasing popularity of smart life, if the video playback device can automatically reco...
