Abstract

Disclosed is a mobile communication terminal supporting a three-dimensional stereo sound effect. The mobile communication terminal has a memory for storing sound data having a three-dimensional stereo sound effect and sound data having no three-dimensional stereo sound effect; a three-dimensional sound generation unit for reading the sound data from the memory when an incoming call is generated or when playback is requested by a user, and for reconstructing the read sound data to have a three-dimensional stereo sound effect; and a speaker for outputting the reconstructed sound data in a type of audible sound.

Claims

1. An apparatus for supporting three-dimensional stereo sound in a mobile communication terminal, the apparatus comprising:

a memory for storing non-three-dimensional sound data;

a three-dimensional sound generation unit for reading the sound data from the memory when an incoming call is generated or when playback is requested by a user, and for reconstructing the read sound data to have a three-dimensional stereo sound effect; and

a sound output unit for outputting the reconstructed sound data in a type of audible sound.

2. The apparatus as claimed in claim 1, further comprising a decoding unit for decoding the sound data read from the memory by a Motion Picture Experts Group-1 Audio layer 3 (MP3) decoding scheme or a MPEG-2 Advanced Audio Coding (AAC) decoding scheme and for transmitting the decoded sound data to the three-dimensional sound generation unit, when the sound data is in an MP3 format or an AAC format.

3. The apparatus as claimed in claim 1, further comprising an encoding unit for encoding the reconstructed sound data without distortion of the three-dimensional stereo sound effect, and transmitting the encoded sound data to the memory.

4. The apparatus as claimed in claim 3, wherein the encoding unit converts the reconstructed three-dimensional sound data into MP3 format or AAC format.

5. The apparatus as claimed in claim 1, wherein the sound output unit is a speaker, which comprises at least two speaker devices so that three-dimensional sound can be played.

6. The apparatus as claimed in claim 1, wherein the sound data is prestored in the memory by a manufacturer, or is download to the memory from a provider server or a user'"'"'s personal computer through a wireless or wired interface.

7. A method for playing and storing sound data having a three-dimensional stereo sound effect in a communication terminal, the method comprising the steps of:

acquiring non-three-dimensional sound data;

reconstructing the acquired sound data to three-dimensional sound data having the three-dimensional stereo sound effect; and

outputting the reconstructed sound data in a type of audible sound.

8. The method as claimed in claim 7, further comprising a step of decoding sound data read from a memory by an MPEG-1 layer 3 (MP3) decoding scheme or an MPEG-2 Advanced Audio Coding (AAC) decoding scheme before reconstructing the read sound data, when the read sound data is in an MP3 or AAC format.

9. The method as claimed in claim 7, further comprising a step of encoding the reconstructed sound data without distortion of the three-dimensional stereo sound effect in order to store the reconstructed sound data in the memory.

10. The method as claimed in claim 9, wherein, in the step of encoding, the reconstructed three-dimensional sound data is converted to an MP3 or AAC format.

11. The method as claimed in claim 7, wherein, in the step of outputting, the three-dimensional sound data is output using at least two speaker devices so that three-dimensional sound can be played.

12. The method as claimed in claim 7, wherein the non-three-dimensional sound data is prestored in the memory by a manufacturer, or is download to the memory remotely from a provider server or directly from a user'"'"'s personal computer.
