Abstract

The invention provides an onboard directional sound system, a control method and a vehicle. The onboard directional sound system comprises: a plurality of audio players corresponding to a plurality ofareas in the vehicle one to one in order to produce sound to the corresponding in-vehicle areas, wherein each audio player comprises an ultrasonic transducer; an input signal control module connectedto the plurality of audio players through a plurality of audio channels, and configured to send at least one audio signal to the corresponding audio player through at least one audio channel; and anonboard computer configured to select a target audio player from the plurality of audio players according to a user requirement, and control the input signal control module to turn on the audio channel corresponding to the target audio player in order to play the user-selected audio signal through the target audio player. The onboard directional sound system of the present invention can provide anin-vehicle auditory experience of a private sound field for different users.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle-mounted directional audio system, a control method and a vehicle. Background technique [0002] In the cockpit of a car, in order to provide a window for the rear passengers to watch videos, in the related art, the existing products arrange the display screens on the back of the front seats, or design the display screens in the rear space The organization fulfills the individual needs of different members in the car. However, in terms of audio, in order to avoid mutual interference of different audio sounds played by users and to protect the privacy of different users, it is usually to add an independent earphone to play audio content. The way of wearing earphones will increase the number of components in the car, and wearing earphones for a long time will cause discomfort or even damage hearing of the user, which is not conducive to the division of the sound field...
