ELI5, why can’t we convert sound to electrical energy for use? I know microphones convert sound to electrical signals but why is producing energy from waste sound not viable?
In: Physics
Microphones don’t generate electricity by the sound, but are fed electricity which powers the magnet allowing the sound to be transferred as a different electric signal when sound is introduced.
It would take a lot of sound to generate electricity. You could have coils and magnets set right to allow the vibrations to move everything just right. This would be not a lot different than turbine or piezoelectric might be.
