Very simple. With the glaring exception of the modern AC induction motor
that in 99% of the stuff we buy, ANY other generator can also be used as
a motor, including the ultra cheap electret condenser microphones, ditto
any speaker, including the peizo tweeters, is also a microphone. Its
part of the basic physics everything we use works by.
