Small speaker reciever?

-is there such thing as like a little speaker reciver to take the speaker wires from the speaker and to have rca cables so i can connect the little speaker to my laptop. i understand that the speaker needs power which it gets from the stereo receiver or receiver amp. i wanna know do they sell little small ones for practical use so its like speaker connects to reciever- receiver to power and rca. thats it just a small simple one.No. but you can buy a small speaker for your laptop. and if you want to connect your laptop to your receiver then all you need is a cable that goes to your laptop to RCA input connection.
