I recently explained how speakers and microphones work to my wife. We were on a long drive and the topic of bluetooth headsets came up. I have a Plantronics 520 headset and the audio quality is pretty good. I casually mentioned that it's amazing how these tiny devices are able to create sound in such a wide range of frequencies and barely use any power. She asked me what's the big deal. I asked if she knew how speakers and microphones (dynamic) work and she said no.

Aha! For the next twenty minutes, I went over the basics of electromagnetism, diaphragms, and sound waves. I explained how so many different components work together to make sure the sound is captured and recreated exceptionally well. I felt pretty excited explaining something I had known since I was a tinkering kid to someone listening intently. After I was done, I said "Isn't that amazing?" and she said "Not as much as you" and smiled. That made my day.



That's funny, I have the same headset and consider the audio quality just barely usable. In any kind of noisy environment I have to crank the volume all the way up and jam the earpiece in, and even then it's still hard to hear and be understood.
