US 2013/0156203 A1 · TERMINAL HAVING A PLURALITY OF SPEAKERS AND METHOD OF OPERATING THE SAME

Abstract

A terminal including a plurality of speakers and a method for operating the same are provided. The method includes generating a request for an audio data playback, processing a signal according to the audio data playback, determining an audio pass which will output the processed signal corresponding to the audio data, when the audio pass which will output the processed signal corresponding to the audio data is determined, dividing an audio signal to be transferred to sub amplifiers in a front terminal of at least one dual amplifier connected to a plurality of speakers in one-to-on correspondence and including two sub amplifiers corresponding to a dual amplifier, transferring the divided audio signal to a corresponding sub amplifier of the dual amplifier, and amplifying the processed signal corresponding to the audio data and transferring the amplified processed signal corresponding to the audio data to the speakers by the dual amplifier.

A terminal having a plurality of speakers, the terminal comprising:

a speaker module including the plurality of speakers;
a speaker support circuit including at least one dual amplifier having two sub amplifiers corresponding to a dual amplifier and amplifying an audio signal to be transferred to corresponding speakers of the plurality of speakers, signal lines connecting the speaker module to a CODEC, and at least one of a dividing circuit and a divider dividing an audio signal from the CODEC to the sub amplifiers of the dual amplifier;
and
the CODEC for separately providing audio data to be supplied to the at least one dual amplifier for a left speaker group and a right speaker group to the speaker support circuit as a differential signal, respectively.
