A question on speakers, drivers, and amps?

Question

do all little speakers that you buy have drivers on them, such as the pc speakers, and car audio speakers?

How can i tell if it has a driver on the back of the speaker(it looks like a magnetic so i cant tell the difference?)

Cause i bought some pc speakers and they 5w and i dont think a driver is on the back, all i see is a magnetic

Answer 1

If they are "powered" cpu speakers usualy get a boost from the subwoofer they are plugged into if they simply plug into the back of your cpu then they probly are not powered

Answer 2

yes thats it

Answer 3

All speakers have some kind of driver on them ,unless you don't count some  tweeters but even a piezo has a cystal which makes the sound.Are you talking about power ,what makes a speaker loud.there are some PC speakers that are powered so they do not need a amp.Other PC speaker need a seperate amp to work.
