AUDIO OUTPUT CONFIGURATION FOR MOVING DEVICES
20230048755 · 2023-02-16 ·

Described herein is a system for recalibrating an audio configuration for mobile or moving devices. The system may configure a multi-device output group to generate synchronous output audio using multiple devices. For example, the output group may include a first device generating a first portion of output audio corresponding to a first channel and a second device generating a second portion of the output audio corresponding to a second channel. If the second device detects motion and/or movement indicating a change in its location, the system may recalibrate the output group to continue generating the output audio without the second device. For example, the first device or a new device can generate the second portion of the output audio instead of the second device. When the second device returns, the system can recalibrate the output group to include the second device again.

METHOD FOR IMPLEMENTING STEREO OUTPUT AND TERMINAL

A first sound element is connected to a left sound-emitting hole and an upper sound-emitting hole. A second sound element is connected to a right sound-emitting hole and the upper sound-emitting hole. A third sound element is connected to a lower sound-emitting hole. When the terminal is in a portrait mode, a processor controls the first sound element and the second sound element to play sound channels on different sides and emit a sound from the left sound-emitting hole and the right sound-emitting hole. When the terminal is in a landscape mode, the processor controls the first sound element and/or the second sound element to play a sound channel on one side and emit a sound from at least one of the left sound-emitting hole, the right sound-emitting hole, and the upper sound-emitting hole, and the processor controls the third sound element to play a sound channel on another side.
