Voice prompt device of crosswalk signals

The utility model discloses a voice prompt device of crosswalk signals. According to the voice prompt device, a microcontroller circuit (2) detects traffic light states of crosswalk signals at real time through a traffic light signal detection circuit (6). When pedestrians pass by, a pedestrian infrared sensor detection circuit (7) detects pedestrians and outputs a signal to the microcontroller circuit (2). According to the traffic light states, the microcontroller circuit (2) controls a prompt voice generation circuit (3). When the red light is on, a voice signal of ''red light danger and no passing'' is outputted; when the green light is on, a voice signal of ''green light, please passing'' is outputted. After power amplification by an audio power amplifier circuit, the voice signal is outputted to a loudspeaker (5) for voice prompt. When there is no pedestrian, any voice prompt is not carried out so as to minimize noise pollution.
