AUDIO PLAYBACK METHOD
Document Type and Number:
WIPO Patent Application WO/2023/155875
Kind Code:
A1
Abstract:
The present application provides an audio playback method. The method comprises: a first device receives a first message sent by a second device. When the first device determines that the second device is within a preset range of the first device, the first device determines a first orientation and a first distance of the second device relative to the first device on the basis of position information of the second device. The first device adjusts the gain of an audio output device located in the first orientation to greater than the gain of an audio output device located in a non-first orientation on the basis of the first orientation and the first distance of the second device relative to the first device. According to the method, gain adjustment is performed on audio loudspeakers in different orientations, so that the position and distance of the second device can be auditorily sensed by a user, thereby improving the interestingness, experience and real-time performance of communicating the traffic situation on the road during driving.
