1. Jumper direct connection: You need a 3.5-to-Lotus jumper. Insert one end of the 3.5 plug into the mobile phone, and one end of the Lotus plug into the aux external audio interface of the speaker.
2. Bluetooth connection: You need a Bluetooth audio receiver, which is specially designed for MP3 speakers with USB port. Plug it into the USB port and follow the instructions so that the phone can be connected to the speaker via Bluetooth.
3. Direct connection of data cable: First, turn on the phone setting option, turn off the USB debugging function, and set the phone to the USB flash drive function. After connecting the data cable, check whether the mobile phone is really in USB flash drive mode. If the phone is in USB flash drive mode, you can't play the music in the phone yet. You need to put the songs in your mobile phone in the root directory of your mobile phone, so you can usually play them.
Note: The first two connection methods can play online music with the mobile phone, and the third one can only play music stored in the mobile phone.
