Is an Amplifier a Speaker?

Let me ask weakly, is an amplifier a speaker? What is the difference between it and a speaker? For example, TDA series, such as 7388 or 7297?
After reading this article below, it seems that TDA is an amplifier that can be used in musical instruments, right?

No, they are not the same.

Compare the results of and and you'll see. The output of an amplifier is an electric current. The higher you turn up the volume, the stronger the electric current, measured in Watt. The output of a speaker is sound, measured in decibel.

But it's not unreasonable to say the a set of computer speakers found by both amplifies the sound coming from the USB or headphone jack it's connected to (makes it louder) and outputs the sound into the air (so you can hear it).

It all depends on the context, that you only give by referring to a type number. That's not enough.
