Reversing radar dynamic scanning response sounding device

The utility model discloses a dynamic scanning response sounding device of a reversing radar, and particularly relates to the technical field of reversing radars, which comprises a reversing radar probe, a radar driving module, a singlechip, a buzzer and a buzzer driving module, the reversing radar probes are installed on a front bumper and a rear bumper of an automobile, the reversing radar probes are connected with the single-chip microcomputer through the radar driving module, and the buzzer is connected with the single-chip microcomputer through the buzzer driving module. The single-chip microcomputer sends PMM waves with a certain frequency to the buzzer driving module through an output pin of the single-chip microcomputer PWM1, the single-chip microcomputer sends a switch control signal to the buzzer driving module through an output pin of the single-chip microcomputer PWM2, and when the switch control signal is at a low level, the buzzer driving module sends the PMM waves to the buzzer, and the buzzer
