1. Confirm that Huawei speakers support USB interface: some Huawei speakers only support Bluetooth, Wi-Fi or network connection to play music. If your speaker doesn't have a USB interface, you can't play songs on the U disk in this way.

2. Insert the U disk into the USB interface on the speaker: find the USB interface on the back or side of the speaker, and gently push the U disk containing songs until it clicks into the socket.

3. Click the U disk mode on the speaker: switch to the U disk input source mode according to the speaker description.

4. Select and play the song you want to listen to: Use various buttons on the control panel to select the song you want to play, and then press the "Play" button to start playing.
