The audio output device (200) can output an audio signal based on the preferred volume included in the first audio setting information. Although the preferred volume has been described as an example, various pieces of information included in the history information can be equally applied to the audio output device (200).

[0109] At least one processor (120) may obtain first location information of a first external device (310) and second location information of a second external device (320) based on the location of the electronic device (100), and may obtain first audio setting information based on the history information, the first location information, and the second location information.

[0110] For example, at least one processor (120) can obtain first location information and second location information using a preset communication method. At least one processor (120) can transmit a signal requesting location information to a first external device (310) and a second external device (320). The first external device (310) and the second external device (320) can transmit a response signal corresponding to the request signal to the electronic device (100). At least one processor (120) can obtain first location information based on a first response signal received from the first external device (310). At least one processor (120) can obtain second location information based on a second response signal received from the second external device (320).

[0111] The electronic device (100) can identify the location of an external device (or terminal device) that transmitted a response signal based on the measured intensity of the response signal and the reception angle of the response signal. The response signal may include identification information of the device that transmitted the response signal and the output intensity of the response signal.

[0112] The response signal may decrease in intensity at a certain rate or function as the distance increases. The electronic device (100) may compare the output intensity included in the response signal with the measured intensity analyzed from the response signal to identify (or calculate) the distance between the external device (or terminal device) that output the response signal and the electronic device (100).

[0113] For example, if the output intensity is 100, the measurement intensity may be 50. The electronic device (100) can identify the location of the electronic device (100) and the external device (or terminal device) that output the response signal based on the value reduced by 50.

[0114] The electronic device (100) can sense the reception angle of the response signal. The electronic device (100) can identify the output direction of the external device (or terminal device) based on the reception angle of the response signal.

[0115] The electronic device (100) can identify the location of an external device (or terminal device) based on the measured intensity of the response signal and the reception angle of the response signal. The electronic device (100) can identify the relative location of the external device (or terminal device) based on the location of the electronic device (100).

[0116] For example, at least one processor (120) may obtain a photographed image including a space in which an electronic device (100) is placed. At least one processor (120) may identify at least one of a first external device (310) or a second external device (320) from the photographed image. At least one processor (120) may obtain first location information of the first external device (310) and second location information of the second external device (320) based on the photographed image.

[0117] At least one processor (120) can obtain first audio setting information based on history information, first location information, and second location information.

[0118] For example, at least one processor (120) may determine a sound pressure level of the audio output device (200) such that an audio signal output from the audio output device (200) is measured at a preferred sound volume included in the history information at a first coordinate corresponding to the first location information. At least one processor (120) may obtain first audio setting information including the determined sound pressure level of the audio output device (200). The sound pressure level may be described as audio size, audio intensity, audio level, audio output level, volume, sound volume, etc.

[0119] For example, at least one processor (120) may determine a sound pressure level of the audio output device (200) such that an audio signal output from the audio output device (200) is measured at a preferred sound volume included in the history information at a second coordinate corresponding to the second location information. At least one processor (120) may obtain first audio setting information including the determined sound pressure level of the audio output device (200).

[0120] At least one processor (120) can obtain third location information of the audio output device (200) and obtain first audio setting information based on the history information and the third location information.

[0121] At least one processor (120) can obtain third location information of the audio output device (200). The method for identifying the location of the audio output device (200) may be the same as the operation for identifying the locations of the first external device (310) and the second external device (320). Duplicate descriptions are omitted.

[0122] For example, at least one processor (120) may determine a sound pressure level of an audio output device (200) output at a third coordinate corresponding to the third location information so as to correspond to a preferred sound volume included in the history information. At least one processor (120) may obtain first audio setting information including the determined sound pressure level of the audio output device (200).
