The speaker is the thing that sound comes out of. The amplifier is what controls the volume. A speaker can work without an amp, but it would only be able to "play back" at the same volume level as the sound went in. (output = imput) The amp is useless on its own. Speakers and amplifiers are used together to electronically amplify sound. We usually talk about a TV or stereo's "speakers" whereas we talk about a guitar or bass "amp." http://www.ehow.com/facts_7358053_amps-vs_-speakers.html

no, sorry. An amplifier makes things bigger. Bigger voltage/signals means louder for sounds. The speaker does the transformation from electrical signals into sound.

This is how I understood it. A speaker is a device that turns electric signals to sound waves. Some speakers are large and require stronger electric signals to power them. In that case you would need an amplifier to "scale up" the signals powerful enough to drive these speakers.
