The lesson remains, 'never give to your child any toys you find in the sea'. Especially dolls. Never pick a doll from the net and take it home. That's a cursed doll, that one is. Don't find a ball and take it home to your boy. That's a cursed ball, that one is. Leave the toys you find and you won't pull spirits from their watery graves. That's the lesson. That's the rule.

Sound is made of wiggling air. Electrons can also be wiggled. If you can convert air-wiggles to electron wiggles, you can send the electric ones down a wire, and do the conversion again to get the air-wiggles back. This is really all a microphone/speaker setup does.
