in response to the first sound output device being positioned within a predetermined range from the plurality of the sound output devices, perform pairing with a second sound output device closest to the first sound output device among the plurality of the sound output devices; and

in response to information about the content source being received from the second sound output device:

request the content source based on the information about the content source to transmit the sound content, a portion of which the second sound output device outputs;

receive the sound content from the content source; and

output a same portion of the sound content output by the second sound output device.

8. A method for controlling a sound output device, the method comprising:

recognizing a plurality of external speakers that receives and outputs sound content from a content source in response to the sound output device being positioned within a predetermined range from the plurality of external speakers, wherein each of the external speakers outputs a different portion of the sound content;

performing pairing with an external speaker closest to the sound output device among the plurality of external speakers;

receiving information about the content source from the paired external speaker;

communicating with the content source based on the information about the content source;

requesting the content source to transmit the sound content, a portion of which the paired external speaker outputs;

receiving the requested sound content from the content source; and

outputting a same portion of the sound content output by the paired external speaker.

9. The method as claimed in claim 8 , further comprising, in response to the pairing with the external speaker closest to the sound output device, receiving connection information about the content source from the paired external speaker, and performing communication with the content source based on the received connection information.

10. The method as claimed in claim 8 , wherein the recognizing the plurality of external speakers comprises in response to the sound output device being positioned within the predetermined range from the plurality of external speakers, recognizing the plurality of external speakers through sensing of at least one of a distance from the plurality of external speakers, a position of the plurality of external speakers, and an arrangement direction of the plurality of external speakers.

11. The method as claimed in claim 10 , wherein the recognizing the plurality of external speakers comprises sensing at least one of the distance from the plurality of external speakers, the position of the plurality of external speakers, and the arrangement direction of the plurality of external speakers using an ultra-wideband (UWB) system.

12. The method as claimed in claim 8 , wherein the predetermined range is changeable in accordance with a user operation.

13. A method for controlling a sound output device, the method comprising:

recognizing a plurality of external speakers in response to the sound output device being positioned within a predetermined range from the plurality of external speakers, wherein each of the external speakers outputs a different portion of a sound content;

performing pairing with an external speaker closest to the sound output device among the plurality of external speakers;

receiving connection information about a display device from the paired external speaker;

communicating with the display device based on the connection information about the display device;

requesting the display device to transmit the sound content, a portion of which the paired external speaker outputs;
