The processor 206 may receive a user's voice through the plurality of microphones 201 . Also, the processor 206 may determine the positional relationship between the electronic device 200 and the user based on a difference in reception time of the user's voice received through each of the plurality of microphones 201 . For example, when receiving the user's voice through the first microphone 201a and the second microphone 201b included in the plurality of microphones 201 , the processor 206 controls the first microphone 201a A positional relationship between the electronic device 200 and the user based on a difference between a first time when the user's voice is received through ) and a second time when the user's voice is received through the second microphone 201b can be judged

According to an embodiment, the processor 206 compares the received first time with the second time, and based on the first threshold value and the compared value, a position between the electronic device 200 and the user relationship can be judged. The electronic device 200 may determine whether the user is within a preset area based on the determined positional relationship.

According to an embodiment, when the value of the received first time is 5 and the value of the received second time is 8, the processor compares the first time with the second time, and a comparison value of 3 can confirm. When the first threshold value is set to 5, the processor 206 may compare the obtained comparison value 3 with a first threshold value 5, in which case, if the comparison value is equal to or greater than the first threshold value, The processor 206 may determine that the user is not located in the preset region, and when the comparison value is less than the first threshold value, determine that the user is located in the preset region.

Accordingly, the processor 206 may determine that the current user is within the preset area.

For example, when the user is located in the preset area, the processor 206 may output at least partially different audio data to each of the plurality of speakers 202 to provide stereo sound. As another example, when the user is located outside the preset area, the processor 206 may output the same audio data to each of the plurality of speakers 202 to provide mono sound. That is, the processor 206 determines whether the user is located in a preset area in which the stereo sound can be provided from the electronic device 200 based on the first threshold value and the second threshold value, and determines the result of the determination. Based on this, you can decide whether to provide stereo sound or mono sound to the user.

As will be described below, referring to FIG. 9 , the first area and the third area may be set as preset areas according to the positions of the first speaker located above the electronic device 200 and the second speaker located below the electronic device 200 . . When the positional relationship between the electronic device 200 and the user determined by the processor 206 is that the user is located in the first area and/or the third area, the processor 206 determines that the user is in the preset area. It is determined that it is located, and in order to provide an optimal sound to the user, at least a portion of different audio data may be output to each of the plurality of speakers 202 to provide stereo sound to the user.

On the other hand, when the processor 206 determines that the user is not located in the preset region in the positional relationship between the electronic device 200 and the user, the processor 206 may provide a mono sound instead of a stereo sound.

According to an embodiment, the processor 206 may receive a user's voice through each of the plurality of microphones 201 , and determine whether to provide a mono sound to the user based on a difference in reception time of the received voice. For example, the processor 206 may determine a positional relationship between the electronic device 200 and the user based on a difference in reception time of a voice received through each of the plurality of microphones 201 .

According to an embodiment, the processor 206 may acquire an image obtained by photographing the object from the camera 204 . Also, the processor 206 may more accurately determine the positional relationship between the electronic device 200 and the user based on the captured image, the time difference between the identified voice signals, and the determined posture of the electronic device. The processor 206 may determine audio data to be output through the plurality of speakers 202 based on the determined positional relationship between the electronic device 200 and the user.

According to an embodiment, when the electronic device 200 is mounted on a cradle, the processor 206 uses the first threshold value, the second threshold value, and the camera 204 to operate the electronic device ( 200) and the user may be determined, and audio data to be output through each of the plurality of speakers 202 may be set based on the determined positional relationship. However, when the posture of the electronic device 200 mounted on the cradle is changed to a posture lying on the ground, the processor 206 determines that the electronic device 200 is lying down through the sensor 203, The positional relationship between the electronic device 200 and the user is determined again based on the user's voice received through each of the plurality of microphones 201 and the image captured by the camera 204, and the plurality of Audio data to be output through each of the speakers 202 may be reset.

According to an embodiment, the processor 206 may determine audio data to be output through the plurality of speakers 202 according to whether the user is located in a preset area. For example, when the user is located in the preset area, the processor 206 may output at least partially different audio data to each of the plurality of speakers 202 to provide stereo sound. As another example, when the user is located outside the preset area, the processor 206 may output the same audio data to each of the plurality of speakers 202 to provide mono sound.

According to an embodiment, the reason that the processor 206 determines that the user is not located inside the preset area and provides the mono sound to the user is that when stereo sound is provided to the user located outside the preset area, the plurality of At least a portion of the audio data output through each of the speakers 202 may cause an extremely aggravated interference phenomenon. Accordingly, since the sound quality of the stereo sound deteriorated due to the interference phenomenon is inferior to that of the mono sound, the processor 206 performs the same through each of the plurality of speakers 202 if the user is not located within the preset area. A mono sound can be provided by outputting audio data.

According to an embodiment, the preset area may be determined according to a location of a plurality of speakers 202 disposed in the electronic device 200 or a size of the electronic device 200 . For example, the preset area may include a sweet spot that provides the best sound quality when stereo sound is provided to the user based on the arrangement positions of the plurality of speakers 202 .

According to an embodiment, when the processor 206 outputs stereo sound through each of the plurality of speakers 202 , the processor 206 uses a filter to prevent crosstalk, which is a phenomenon that occurs when audio data interferes with each other.
