Mechanical energy to electrical energy
a speaker converts electrical energy into mechanical energy also called kinetic energy some energy is also lost in the form of thermal energy.
Mechanical energy to electrical energy
Crating the Circuit alone would be electric energy and when the speaker is operating it would turn into sound energy.
A speaker converts the energy of discrete electrical impulses to the energy of sound waves in the air.
IF you use speaker as microphone, you can use it as a transducer to convert soun energy into electrical signals
Mechanical to Sound.
you cant, you can only use type chat
you use kinetic energy when you eat
