    That’s one type. Condenser style microphones are another. Even regular speakers can be used as (mediocre) microphones.

    But “generating electricity by bending crystals” is by far the coolest one.

      It for sure does not surprise me that other kinds of microphones exist, but I strongly agree with your last sentence.
