How does crystal radio detect radio signals?

Crystal Radio instantly converts the radio signal into a signal that is audible to the human ear. Since the radio does not use external energy, the energy source comes directly from the radio waves themselves, this radio detects in the AM band those that have traveled from stations (transmitters) thousands of miles away.
