So, install the speakers next to the computer. Now inspect the wires that come out from behind one of the blocks of columns. You need two wires: power and audio cable. The power cord can be plug to 220V socket and USB connector (if column is small). The audio cable has a 3.5 mm Jack (like normal headphones).
Now plug the power cord into a 220V outlet (or USB socket on the laptop) and the audio cable into the headphone Jack on the laptop. You can turn on the speakers to adjust the volume to the desired volume and enjoy the sound.
