Embodiments of the present invention provides a method and apparatus for playing audio, applied to the field of audio playback, for solving the problem of mismatch between audio information and video information played by the mobile terminal due to changes in the spatial attitude of the mobile terminal in the process of playing multimedia files. Embodiments of the present invention provides a method of playing audio for a mobile terminal having a spatial attitude sensor, the mobile terminal comprises at least 3 speakers, said at least 3 speakers are not in the same straight line, the method comprising: when the mobile terminal is rotated on the screen, the spatial attitude information is obtained; Controls the audio content played by each speaker according to the spatial attitude information, so that the speaker located on the left side of the currently playing video information plays the left channel, and the speaker located on the right side of the currently playing video information plays the right channel. Embodiments of the present invention provides a method and apparatus for playing audio may be applied to a mobile terminal having a spatial attitude sensor.
Description
technical field [0001] The invention relates to the field of audio playback, in particular to a method and device for playing audio. Background technique [0002] With the development of society, more and more multimedia files are played on mobile terminals. During the playback process, since the direction of the audio signal output by the channel is fixed, how to make the sound effect of playback change with the change of the spatial posture of the mobile terminal become a problem to be solved. In the prior art, a mobile terminal uses dual speakers to play an audio signal, while playing an audio signal through a left channel while playing another audio signal through a right channel, so as to achieve a stereo effect. [0003] Mobile terminals such as mobile phones and tablet computers can be used to play multimedia files, wherein the played multimedia files are mostly composed of audio information and video information. [0004] Currently, mobile terminals are mostly prov...
