Problems solved by technology

At present, each audio-visual equipment is plugged into the porous power socket separately, which is inconvenient to use, and there are many unsafe factors, such as unstable sound and image caused by unstable mains power, distortion of sound and image caused by noise interference, and overvoltage of the power supply burns the sound. like equipment etc.
Chinese patent "special socket for home theater" (CN2378855Y) is characterized in that a multipurpose button switch is arranged on the original porous power socket, one of the buttons of the multipurpose button switch is used as a zero circuit, and other buttons are connected in series with the jacks of the porous power supply respectively. But there is still no change to the power supply
So far, no dedicated power supply for home theater has come out
