Sound energy can be converted to electrical energy using a device called a microphone. When sound waves hit the microphone's diaphragm, it vibrates, converting sound waves into electrical signals. These electrical signals can then be amplified and processed to generate electrical energy.

A microphone is a device that converts sound energy into electrical energy. Sound waves cause a diaphragm in the microphone to move, which then generates an electrical signal that represents the sound.
A microphone is a device that converts sound energy into electrical energy.
A loudspeaker or a speaker would transform electrical energy into sound energy by converting electrical signals into vibrations that produce sound waves.
A speaker is the device that converts electrical energy into sound energy. An electrical signal is sent to the speaker, which causes a diaphragm to vibrate and produce sound waves that we hear as sound.
The electrical energy from the outlet powers the radio, which then converts that electrical energy into sound energy that you hear. The transformation is from electrical energy to sound energy.
