Abstract
An electronic device including a signal generating circuit and a movable sensing circuit is provided. The signal generating circuit generates a sensory signal through a signal source. The movable sensing circuit generates a feedback signal in response to a detection signal from the signal generating circuit, and transmits the feedback signal to the signal generating circuit. The signal generating circuit obtains a first distance value between the signal source and the movable sensing circuit based on the feedback signal, and adjusts the intensity of the sensory signal according to the first distance value.
