What to do with an old radio SPEAKER

Hi, I've got a speaker from my butchered old radio. I took its whole part, including wires that it connects, then I told myself why not make my self my personal speaker where I can play it in bluetooth or in drive. But I don't have and materials. What's the missing piece? 
I think i am missing this:
Bluetooth module
Usb Port
ON/OFF switch
volume module(some kind)
yes i need a rechargeable battery
some kind of chip board (arduino i think)

Am I correct?
