Two mobile phones
The phone needs to be full, with the phone with the higher pixel camera broadcasting live, and the other phone playing background music.
The sound card is connected.
At this time, you need a 3.5-3.5 mobile phone connection cable (the connection cable that comes with the purchase of the sound card), this connection cable is connected to the music input interface of the sound card, and the other end is connected to the mobile phone. If the mobile phone interface Type is Type-C, you need to bring your own conversion interface. Connect the first phone
Use the 3.5-3.5 phone cable to plug one end into the [Music input] port of the sound card and the other end into the phone headphone jack. If the phone uses a Type-C interface, then you also need a conversion cable connection. That's how you connect your phone to your sound card. Generally new mobile phones, especially Xiaomi and Apple, which have canceled the headphone jack, need to use the Type-C adapter. Because this interface on the mobile phone is fast to charge, supports blind insertion (can be inserted back to front), supports two-way charging, and has fast data transmission speed. It is expected that all mobile phones will use this interface in the future.
3. Connect a second phone
Here the audio cable only needs to be connected to the red one. Plug the red connector into the earbud output of the sound card, then connect the other one to the phone. The interface Type of my live broadcast mobile phone is Type-C, so I use a adapter.
When the connection is finished, fix the live phone to the tripod. Accompaniment mobile phone is not fixed, convenient to pick up at any time to change the background music.
Turn on the Bluetooth Settings in your phone and you'll be done
