The moving signal receiving unit is used to receive the scrolling control signal provided when the mouse wheel scrolls. The signal comparison and analysis unit is used to analyze the pressing control signal and the scrolling control signal, and provide a corresponding volume control command; finally, the volume control unit adjusts the system playback volume of the operating system according to the volume control command. The above-mentioned patent discloses that the volume of the system playback of the operating system is adjusted by using the scrolling control signal provided when the mouse scrolls.

Generally, the cable TV has a large number of channels, and the user can use the remote controller to select the channel to watch. The audio signal output by each cable TV channel is different in size. When the user watches a movie program on a certain channel, the volume of the broadcast may be too low and must use the remote control to adjust the TV to play a larger volume; when using Or change the channel that TV broadcasts, when watching the program of another channel, the volume that it broadcasts may be too big and must utilize remote controller to adjust TV to broadcast less volume again. After changing the channel, the user must properly adjust the volume of the TV broadcast according to the size of the output audio signal of each channel, so as to obtain a more comfortable listening effect.

Current electronic products such as televisions, radios or computers cannot allow users to pre-set the volume of sound corresponding to each channel and store the settings. When the user changes a certain channel, the electronic product can play the function of presetting an appropriate sound level corresponding to the channel to obtain a more comfortable listening effect. The aforementioned two patent cases also cannot achieve this function.
