Question

What is an example of an energy transformation from electrical to sound energy?

Answer 1

How about a Microphone!

Answer 2

The actual process involves beginning with sound, converting it to electric signals, then converting it back again to sound.

For example: the microphone picks up the sound waves of the singer or talker, converts it to an electric signal, then an electronic device amplifies it and converts it back to sound with speakers for the audience to hear

So,you can say that Audio Speaker is actually a device that converts electrical energy into sound energy!
