Orientation detection-based directional vehicle horn opening platform

The invention relates to a directional vehicle horn opening platform based on orientation detection. The platform comprises a loudspeaker array, a horn triggering mechanism and field driving equipment, wherein the loudspeaker array comprises a plurality of loudspeaker units disposed at different positions of a vehicle body, and the different positions respectively correspond to different directions of the vehicle; the horn triggering mechanism is arranged in the center of a steering wheel and used for sending a triggering detection command when the sensed pressing pressure is larger than or equal to a preset pressure threshold value; and the field driving equipment is used for starting one or more loudspeaker units of which the positions are close to or consistent with a current identification direction relative to the direction of the vehicle when receiving the trigger detection command and the current identification direction. The directional vehicle horn opening platform based on orientation detection is intelligent in design, mute and environmentally friendly. As whistling warning operation is only carried out on nearby human bodies or vehicles and directions in which many human bodies or vehicles are distributed, the on-site warning effect is ensured while the environmental pollution is reduced.
