[0215] The electronic device (100) can identify at least one of the placement position or placement angle of the audio device (200) based on at least one of the time of transmitting the test audio signal, the time of receiving the test audio signal, the waveform of the transmitted test audio signal, and the waveform of the received test audio signal.

[0216] According to one embodiment, the electronic device (100) can identify at least one of the placement position or the placement angle of the audio device (200) by outputting a test communication packet.

The communication interface (130) may include a first communication module and a second communication module. The electronic device (100) may obtain a first angle of the test communication packet obtained through the first communication module and a second angle of the test communication packet obtained through the second communication module. The electronic device (100) may identify at least one of the placement position or the placement angle of the audio device (200) based on the first angle and the second angle.

[0223] For example, the audio device (200) may include a plurality of communication modules. Each of the plurality of communication modules may transmit a test communication packet. The audio device (200) may include a third communication module and a fourth communication module. The audio device (200) may transmit a test communication packet at a first time point through the third communication module, and may transmit a test communication packet at a second time point through the fourth communication module.

[0224] The electronic device (100) can obtain a third angle of a test communication packet received at a third point in time and a fourth angle of a test communication packet received at a fourth point in time.

[0225] The electronic device (100) can identify at least one of the placement position or placement angle of the audio device (200) based on the third angle and the fourth angle.

[0226] According to various embodiments, the third and fourth communication modules of the audio device (200) may each transmit different test communication packets. When transmitting different communication packets, the third and fourth points in time may be the same. This is because waveform analysis can be used to determine which module transmitted the packet.

[0234] For example, if the audio device (200) is a speaker providing three channels, the audio data may include audio signals corresponding to each of the three channels (three audio signals).

[0235] The electronic device (100) can obtain audio data considering the placement position and placement angle of the audio device (200). This is because the audio channels output are different depending on at least one of the placement position or placement angle of the audio device (200).

[0440] Referring to the embodiment (3500) of FIG. 35, the electronic device (100) can analyze the space in which the electronic device (100) is placed. The electronic device (100) can obtain sensing data to analyze the space in which the electronic device (100) is placed. The electronic device (100) can include a sensor unit. The electronic device (100) can obtain spatial data through the sensor unit.

[0441] The sensor unit may include at least one of a 3D depth camera, a ToF (Time of Flight) sensor, and an image sensor. The electronic device (100) may generate a spatial map in which the electronic device (100) is positioned based on the sensing data. The electronic device (100) may identify the location of the electronic device (100) and the location of the audio device (200) in the spatial map. The spatial map may be a two-dimensional map or a three-dimensional map.

[0442] The electronic device (100) can divide the spatial map into a preset number of segments. The preset number can be determined based on the overall size of the spatial map or the number of audio devices (200) connected to the electronic device (100). The larger the size of the spatial map, the larger the preset number. The larger the number of audio devices (200) connected to the electronic device (100), the larger the preset number.

[0443] The electronic device (100) can divide the entire space of the space map into a preset number of spaces. The division criteria may be front, back, left, right, etc. In the embodiment of FIG. 35, it is assumed that the preset number is 4.

When the audio device (200) is placed in the third space (3503), the electronic device (100) can obtain audio data by assigning a rear left channel (Rear-L) to the audio device (200).

[0448] For example, the electronic device (100) can determine whether an audio device (200) exists in the fourth space (3504) corresponding to the right rear side based on the direction in which the electronic device (100) is viewed, based on the placement location and space map of the audio device (200). When the audio device (200) is placed in the fourth space (3504), the electronic device (100) can obtain audio data by assigning a rear-right channel (Rear-R) to the audio device (200).

[0449] According to another embodiment, the electronic device (100) can obtain audio data by considering the direction in which the plurality of speakers included in the audio device (200) are facing.

[0450] When the audio device (200) is placed in the first space (3501), the electronic device (100) can obtain audio data by selectively allocating the right channel (R) only to a speaker facing the x,y plane (see FIG. 12) among the multiple speakers included in the audio device (200).

[0451] When the audio device (200) is placed in the second space (3502), the electronic device (100) can obtain audio data by selectively assigning the left channel (L) only to a speaker facing the x,y plane (see FIG. 12) among the multiple speakers included in the audio device (200).

[0452] When the audio device (200) is placed in the third space (3503), the electronic device (100) can obtain audio data by selectively assigning the rear left channel (Rear-L) only to a speaker facing the x,y plane (see FIG. 12) among the multiple speakers included in the audio device (200).

[0453] When the audio device (200) is placed in the fourth space (3504), the electronic device (100) can obtain audio data by selectively assigning the rear right channel (Rear-R) only to a speaker facing the x,y plane (see FIG. 12) among the multiple speakers included in the audio device (200).

[0455] Referring to FIG. 36, a control method of an electronic device storing audio content includes a step of identifying an audio device connectable to the electronic device (S3605), a step of obtaining channel configuration information related to a plurality of speakers included in the audio device from the audio device, a position response signal indicating a position of the audio device, and tilt angle information indicating a degree to which the audio device is tilted in space (S3610), a step of identifying a placement position of the audio device based on the position response signal (S3615), a step of identifying a placement angle of the audio device based on the tilt angle information (S3620), a step of obtaining audio data for outputting different audio signals to each of a plurality of speakers of the audio device based on the audio content, the channel configuration information, the placement position, and the placement angle (S3625), and a step of transmitting the audio data to the audio device (S3630).

[0456] Channel configuration information is a control method that indicates a channel corresponding to each of multiple speakers included in an audio device.

[0457] The control method may include a step of re-identifying a placement angle when tilt angle information is changed, a step of changing audio data based on audio content, channel configuration information, placement position, and the re-identified placement angle, and a step of transmitting the changed audio data to an audio device.
