How does volume work on computers? How does my computer bring the volume up or down?

eli5: You have a drum. You tap it very lightly and it makes a small sound. You bang on it with all your might and it makes a very very loud sound.
Energy that you input into the sound making directly effects the volume of the sound coming out. Speaker volume is effected by controlling the energy going into the speaker. It’s the same way a dimmer switch on a light bulb works: lower energy, dimmer light. Higher energy, brighter light. Speakers are the same way.
