An electronic device capable of auto-tracking a sound source includes a driving member including a rotor, a housing fixed to the rotor; a first sound sensor positioned on the housing for detecting sound from the sound source to generate a first sound signal. A second sound sensor positioned on the housing spaced from the first sound sensor for detecting sound from the sound source to generate a second sound signal. A third sound sensor positioned on a perpendicular bisector of the connection line of the first sound sensor and the second sound sensor for detecting sound from the sound source to generate a third sound signal. A microphone positioned on a perpendicular bisector of the connection line of the first sound sensor and the second sound sensor, and a processor positioned in the housing for analyzing intensities of the three sound signals, and controlling the driving member to rotate.
