To play music on the active speaker/audio amplifier from our smartphone, computer tablet, laptop, etc, we can use audio cable or using the bluetooth for connection.
Especially those using bluetooth, it will be deemed a lot of advantages, because we are free to move while carrying a smartphone, sleeping, sitting, even while walking we can pick and choose favorite songs.
If you have an audio active speaker or audio amplifier without Bluetooth receiver on it, You can add/install bluetooth separately.
Nowadays you can get the bluetooth audio receiver easily and the price in not expensive.
I use generic bluetooth audio receiver, as show below, the quality is very good.
