I'm not lying to you. Of course, you have to connect the TV to something, which is not sold in the market. I assembled it myself. Assembly parts are available in the market, but it's hard to buy! For example, if you need to use the power amplifier of your mobile phone, you have to take it apart. I wonder if you are willing to give up? Spend around 300 yuan.
If you want to know what I told you to use, assemble and copy!
