Key Differences
A speaker is designed to produce audio output from electrical signals, focusing on sound clarity and fidelity. On the other hand, an amplifier is used to increase the power of these signals before they reach the speaker.
Speakers come in various forms, such as dynamic, planar magnetic, and electrostatic, each with unique sound characteristics. In contrast, amplifiers vary mainly in terms of power output and circuit design, impacting sound quality and volume.
The primary function of a speaker is to convert amplified electrical signals into audible sound through its components like woofers and tweeters. Amplifiers, however, serve to manage and boost the audio signal's strength without actually producing any sound.
In a typical audio system setup, the quality of the speaker is crucial for the final audio output, emphasizing accurate sound reproduction. Amplifiers enhance this by ensuring that the speaker receives enough power to perform efficiently.
While speakers directly interact with the listener by producing sound, amplifiers work behind the scenes, integral for driving the speaker but not directly noticed by listeners.

Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output.
