US 2017/0289723 A1 · AUDIO OUTPUT CONTROLLING METHOD BASED ON ORIENTATION OF AUDIO OUTPUT APPARATUS AND AUDIO OUTPUT APPARATUS FOR CONTROLLING AUDIO OUTPUT BASED ON ORIENTATION THEREOF

Abstract

Provided is a method of controlling an audio output according to an orientation of an audio output apparatus, performed by the audio output apparatus, the method including receiving a stereo signal; detecting the orientation of the audio output apparatus using a sensor; outputting the stereo signal to a left speaker unit and a right speaker unit from a viewpoint of a user who views a front surface portion of the audio output apparatus on which two speaker units are arranged; and down-mixing the stereo signal and outputting the down mixed signal to at least one among an upper speaker unit and a lower speaker unit from the user's viewpoint.

A method of controlling an audio output according to an orientation of an audio output apparatus, performed by the audio output apparatus, the method comprising:

receiving a stereo signal;
detecting the orientation of the audio output apparatus using a sensor;
outputting the stereo signal to a left speaker unit and a right speaker unit on a front surface portion of the audio output apparatus on which two speaker units are arranged in current arrangement of speaker units;
and
outputting a signal obtained by down-mixing the stereo signal to at least one of an upper speaker unit and a lower speaker unit in the current arrangement of the speaker units.
