This application relates to a method, device and unmanned vehicle for directional playback of sound by a vehicle, which is applied to the technical fields of unmanned vehicles, unmanned driving and automatic driving. The system and device of the present invention obtain the Crowd information: control the playback direction and volume of the sound playback device according to the selected crowd, so as to play the sound to the crowd. The unmanned vehicle also includes a vehicle trajectory planning module and a regional crowd monitoring system. The unmanned vehicle obtains the crowd flow information in the current area from the regional crowd monitoring system through the vehicle trajectory planning module for targeted directional playback sound. According to the information of the surrounding crowd, the present invention plays the sound in a directional way, reasonably controls the size and distribution of the sound, and facilitates the efficient use of loudspeakers, directional loudspeaker arrays and other sound amplification equipment. The system and device provided by the present invention can also select a specific playing partner from the crowd, Improved the pertinence of sound playback for unmanned vehicles.
