An automatic return system includes a charging station and an automatic traveling device. A sound wave transmitter is disposed on the charging station, and the automatic traveling device includes a sound wave receiver, a processor, and a controller. Controlling, by the controller when an automatic traveling device starts to return, a sound wave receiver to continuously detect sound waves in different directions transmitted by a sound wave transmitter; performing, by the processor, intensity analysis on the sound waves in different directions continuously detected by the sound wave receiver, and obtaining the direction of a sound wave with the highest sound intensity; and controlling, by the controller, a traveling direction of the automatic traveling device according to the direction of the sound wave with the highest sound intensity, so that the automatic traveling device returns to the charging station.
