The invention discloses a vehicle-mounted pedestrian warning device based on a multi-sound-source system, and belongs to the technical field of driving safety auxiliary devices. The vehicle-mounted pedestrian warning device comprises a shell, a PCB and a loudspeaker; the PCB and the loudspeaker are both arranged in the shell; an acquisition module, a conversion module, a noise reduction module, a filtering module, an audio processing module and a control module are arranged on the PCB; the audio processing module is connected with the audio output module, and the audio output module is connected with the loudspeaker; and the control module is connected with the loudspeaker. The vehicle-mounted pedestrian warning device based on the multi-sound-source system is an integrated low-speed pedestrian alarm based on an integrated loudspeaker and a controller as an execution core, multiple sound effects are achieved by integrating a plurality of modules on a PCB to be selected by a user, the requirements of a pure electric vehicle and a plug-in hybrid electric vehicle are met at the same time, and the vehicle-mounted pedestrian warning device based on the multi-sound-source system is suitable for being used by the user. When the vehicle is started and the vehicle speed is lower than 20Km/h, the function requirement of giving out proper prompt sound to people outside the vehicle can be met, and personalized choices are provided for drivers and passengers.
