The product integrates a series of basic elements such as audio box, audio shield tube and line square.It is a line device concealed in the wall.

First, in order to eliminate the problem of signal interference caused by the winding of strong and weak wire,The product uses a strong electric special tube and a weak current to shield the round tube, which guides the strong and weak electricity to separate the lines.

At the same time, in order to ensure the installation procedure is simple and the installation quality is stable, there is a horizontal reference bubble in the video box on the upper and lower ends to avoid the horizontal repetition of the adjustment work that may occur at the time of installation.

The product has entered the stage of crowdfunding production, which will be sold in some Tongzheng outlets this month.
