I have never really fully understood how a speaker vibrating air molecules which then in turn vibrate the membrane in your ear works. How can a speaker make multiple sounds at the exact same time if its based on movement of a physical object?
In: Physics
Your ear does only one thing; vibrate. Your brain interprets all the overlapping sounds it hears in those vibrations. A microphone does the same thing and turns vibrations into electrons. A speaker does the inverse. The first telephones only had a single combination mouth / ear piece. It all works because the multiple waves from the environment combine together. This happens whether the waves are air, electrons, light, etc.
