How to sing Be There Or Be Square.
You'd better look at the instruction manual, and you should have an introduction to the functions and methods!
By the way, this also has a AUX function, that is, you can connect the phone to the loudspeaker via the audio line, and use it as a small speaker.
The loudspeakers are able to support the U disk, TF card, do not know the Be There Or Be Square you use can not support, I use the successful E180C can be directly inserted U disk and use the TF card,
