Answer: "sound wave → electrical signal → radio wave → sound wave"
Why: A microphone converts the original sound into an electrical audio signal, that audio signal modulates a radio-frequency carrier which is sent out as a radio wave. The receiver antenna picks up the radio wave, demodulates it back to an electrical audio signal, and a speaker converts that electrical signal back to sound.
