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.

Claims

1. 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.

2. The terminal of claim 1, wherein the dividing circuit comprises:

a first dividing circuit provided between the at least one dual amplifier and the CODEC, and separately providing an audio signal to be supplied to a left speaker group to sub amplifiers corresponding to a specific dual amplifier; and

a second dividing circuit provided between the at least one dual amplifier and the CODEC, and separately providing an audio signal to be supplied to a right speaker group to sub amplifiers corresponding to another dual amplifier

3. The terminal of claim 1, wherein the plurality of speakers are disposed in a predetermined region adjacent to respective corners of the terminal.

4. The terminal of claim 3, further comprising a sensor for collecting a sensor signal to operatively determine a rotating state of the terminal.

5. The terminal of claim 4, wherein the plurality of speakers are connected to the sub amplifiers in one-to-one correspondence, and one of an audio signal to be supplied to a left speaker group and an audio signal to be supplied to a right speaker group may be outputted according to a rotating state of the terminal.

6. The terminal of claim 5, wherein one of an audio signal to be supplied to a left speaker group and an audio signal to be supplied to a right speaker group is changed and outputted to the predetermined number of speakers of the plurality of speakers according to the rotating state of the terminal, and

wherein an audio signal to be supplied to a left speaker group or the right speaker group is continuously outputted to a remaining number of speakers of the plurality of speakers although the rotating state of the terminal is changed.

7. A method of operating a terminal having a plurality of speakers, the method comprising:

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 amplifiers.

8. The method of claim 7, wherein the dividing of the audio signal comprises:

dividing and transferring the audio data received from a CODEC to be transferred to a left speaker group to sub amplifiers included in one of the at least one dual amplifier; and

dividing and transferring the audio data received from the CODEC to be transferred to a right speaker group to sub amplifiers included in a remaining one of the at least one dual amplifier.

9. The method of claim 8, further comprising determining a rotating state of the terminal to determine whether the terminal is operated in a landscape mode or a transverse mode.

10. The method of claim 9, wherein the transferring of the divided audio signal comprises:

when the terminal is arranged in the landscape mode, transferring an audio signal to be transferred to the left speaker group to speakers of the speakers which are biased in a left side of the terminal in the landscape mode relative to a center of a terminal screen; and

transferring an audio signal to be transferred to the left speaker group to speakers of the speakers which are biased in a right side of the terminal in the landscape mode relative to the center of the terminal screen.

11. The method of claim 9, wherein the transferring of the divided audio signal comprises:

when the terminal is arranged in the transverse mode, transferring an audio signal to be transferred to the left speaker group to speakers of the speakers which are biased in a left side of the terminal in the transverse mode relative to a center of a terminal screen; and

transferring an audio signal to be transferred to the left speaker group to speakers of the speakers which are biased in a right side of the terminal in the transverse mode relative the center of the terminal screen.

12. The method of claim 9, wherein the transferring of the divided audio signal comprises transferring audio data of an identical direction to two speakers of the speakers regardless of a mode change when the terminal is changed to the landscape mode or the transverse mode, and transferring audio data to be transferred to the left or right speaker group to a remaining two speakers according the mode change.

13. A terminal for outputting an audio signal, the terminal comprising:

a plurality of speakers;

at least one dual amplifier each of which comprises two sub amplifiers;

a controller configured to determine which of the at least one dual amplifier corresponds to a left speaker group and which of a remaining of the at least one dual amplifier corresponds to a right speaker group based on an orientation of the terminal during operation, to operatively divide the audio signal according to which of the left speaker group and the right speaker group is to output the audio signal, and to operatively transfer corresponding divided portions of the audio signal to the left speaker group and the right speaker group based on the orientation of the terminal during operation.
