The circuit utilizes the delaying method which delays the ultrasonic echo signals successively and generats the stereo audible warning signals for the detecting the obstacles. The circuit includes a transmitting unit (10), a receiving unit (20), a signal processing unit (30) converting the echo signals to the audible signals for detecting the direction of the obstacle, and a system control unit (40).
