A pedestrian sound warning device having an active early-warning function for use in a new-energy vehicle, and the pedestrian sound warning device comprises: an infrared detection module (28), for detecting whether there are people around the vehicle and outputting an infrared detection signal; a main control module (21), for receiving the infrared detection signal and transmitting an audio play command to an audio chip module (22), according to the infrared detection signal; the audio chip module (22), for transmitting sound signals to a power amplifier module (23); and the power amplifier module (23), for driving a speaker (27) to play the sound signals. The warning device is equipped with the infrared detection module (28) and an ambient sound signal acquisition module (26) to actively determine whether a sound warning needs to be sent; therefore, the warning device is able to minimize and reduce occurrences of pedestrian sound warnings as much as possible, and solve the problem wherein pedestrian sound warnings are always sounding regardless of whether there is a pedestrian in front of the vehicle; further, the warning device allows a user to download a sound of his or her choice, and features other functions such as a road memory function knob (29), making the device smarter.
