METHOD AND DEVICE FOR PLAYING 3D SOUND

摘要

The present invention relates to a device and a method for playing 3D sound by means of a speaker and one or more microphones. A method for playing 3D sound according to the present invention comprises the steps of: receiving through wire or wireless communication a first signal which is an audio signal comprising any one of left direction information and right direction information and a second signal which is an audio signal comprising the other one of the left direction information and the right direction information; receiving through microphones a third signal that is being output from an external speaker; determining, on the basis of a fourth signal that is to be output from the speaker; and generating the fourth signal from the second signal by means of the determined variable.

1. A method for playing a stereophonic (3D) sound in a portable device having a first speaker and a microphone, the method comprising:
receiving an audio signal including one of left direction information and right direction information as a first signal and an audio signal including the other one of the left direction information and the right direction information as a second signal from a media playing device through wired or wireless communication; receiving a third signal output by a second speaker of the media playing device through the microphone; determining a compensation parameter for a fourth signal to be output through the first speaker on the basis of the first signal and the third signal; and generating the fourth signal from the second signal by using the determined compensation parameter.
