What is the difference between a microphone and a speaker? A microphone and speaker. Um, okay, well the difference is a microphone is a device that captures sound waves and converts them into electrical signals, whereas a speaker is a device that takes electrical signals and converts them back into sound waves. Essentially, a microphone is an input device for audio, while a speaker is an output device. Microphones are used to record or transmit sound, whereas speakers are used to play or broadcast sound.
