[0056] The power management module 188 can manage the power supply to the electronic device 101. According to an embodiment, the power management module 188 can be implemented as at least part of, for example, a power management integrated circuit (PMIC).

[0057] Battery 189 can power at least one component of electronic device 101. According to embodiments, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable rechargeable battery, or a fuel cell.

[0058] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and supporting direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). A corresponding one of these communication modules can communicate via a first network 198 (e.g., a short-range communication network, such as Bluetooth). TMThe wireless communication module 192 can communicate with external electronic devices 104 via a Wi-Fi Direct or Infrared Data Association (IrDA) network or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a local area network (LAN) or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can use user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196 to identify and verify electronic devices 101 in the communication network (such as a first network 198 or a second network 199).

[0059] Wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies (e.g., new radio (NR) access technologies). NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), or ultra-reliable low-latency communication (URLLC). Wireless communication module 192 can support high-frequency bands (e.g., millimeter-wave bands) to achieve, for example, high data transmission rates.

In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas by, for example, communication module 190.

[0062] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via inter-peripheral communication schemes (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0063] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199.

According to an embodiment, all or some operations to be performed on electronic device 101 can be performed on one or more of external electronic devices 102, external electronic devices 104, or server 108.

Electronic device 101 may provide the result as at least a partial response to the request, with or without further processing of the result. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing can be used.

[0064] Figure 2 This is a view illustrating the operation of a wearable electronic device based on rotation according to an embodiment.

[0065] According to an embodiment, electronic device 201 (e.g., Figure 1 The electronic device 102 can be displayed (e.g., Figure 1 Display module 160 or Figure 2 The display 260) outputs an image. In this case, wearable electronic devices 301a and 301b (e.g., connected to electronic device 201) output an image. Figure 1Each of the electronic devices 101 can be output via an output device (e.g., Figure 1 155 or audio output module Figure 3 The output device 360 ​​outputs the sound image. Wearable electronic devices 301a and 301b can perform spatial audio functions based on head tracking technology. Spatial audio function can refer to the function of controlling the position of the sound image so that the user wearing the wearable electronic devices 301a and 301b can perceive that the sound is output from a specific direction. Spatial audio function based on head tracking technology can refer to the function of controlling the position of the sound image to be positioned in the reference direction even when the head of the user wearing the wearable electronic devices 301a and 301b is rotated from a reference direction to a specific direction. When the spatial audio function based on head tracking technology is performed in the wearable electronic devices 301a and 301b, the user wearing the wearable electronic devices 301a and 301b can perceive that the sound is output from the reference direction. For example, the user wearing the wearable electronic devices 301a and 301b can perceive that the sound is output from the front direction (e.g., the direction along which the electronic device 201 is located) before rotating their head. Users wearing wearable electronic devices 301a and 301b can feel the sound output from the left side (e.g., the direction in which electronic device 201 is located) after rotating their head to the right.

[0066] According to embodiments, wearable electronic devices 301a and 301b can be based on sensors (e.g., Figure 1 Sensor module 176 or Figure 3 The sensor 376 obtains sensing values ​​to determine how much the wearable electronic devices 301a and 301b have rotated from a reference direction, and the direction of the output sound image is positioned relative to the sound in the first direction. The reference direction can refer to the frontal direction of the user wearing the wearable electronic devices 301a and 301b or the direction along which the user views the electronic device 201. Therefore, the user can perceive sound being output from the reference direction through each of the wearable electronic devices 301a and 301b.

[0067] According to an embodiment, wearable electronic devices 301a and 301b can determine whether to activate the ambient sound listening function based on the degree to which wearable electronic devices 301a and 301b rotate from a reference direction toward a specific direction.

[0068] For example, refer to Figure 2 (a) Wearable electronic devices 301a and 301b can identify a reference orientation. For example, wearable electronic devices 301a and 301b can use sensors (e.g., Figure 3The sensor 376 identifies the reference orientation. Alternatively, wearable electronic devices 301a and 301b can be connected via a communication module (e.g., Figure 1 Communication module 190 or Figure 3 The electronic device 201 can identify the reference direction via the communication module 390. The electronic device 201 can identify the reference direction via the wearable electronic devices 301a and 301b. The reference direction can refer to the frontal direction of the user wearing the wearable electronic devices 301a and 301b or the direction along which the user views the electronic device 201. According to an embodiment, the wearable electronic devices 301a and 301b can output notification information via the output device 360 ​​to cause the user wearing the wearable electronic devices 301a and 301b to gaze at the reference direction for a predetermined time. According to an embodiment, the electronic device 201 can also identify the reference direction via a display (e.g., a...). Figure 1 Display module 160 or Figure 3 The display 260 outputs notification information to instruct a user wearing wearable electronic devices 301a and 301b to gaze in a reference direction. According to an embodiment, when it is detected that a user has gazed in a first direction for a predetermined time, wearable electronic devices 301a and 301b can determine the first direction as the reference direction.

[0069] refer to Figure 2 (b) Wearable electronic devices 301a and 301b can detect whether they have rotated from a first direction using sensor 376. According to an embodiment, wearable electronic devices 301a and 301b can detect from the first direction to a second direction using sensor 376. For example, the second direction could be a rightward direction relative to the first direction. However, the second direction being a rightward direction is merely an example, and the inventive concept is not limited thereto.

[0070] Wearable electronic devices 301a and 301b can obtain a rotation angle between a first direction and a second direction. Wearable electronic devices 301a and 301b can identify whether the rotation angle, indicating the degree of rotation, is greater than a specified value. When the rotation angle is detected to be greater than the specified value, wearable electronic devices 301a and 301b can activate an ambient sound listening function. For example, the ambient sound listening function may refer to outputting through an output device 360 ​​via a microphone included in at least one of the wearable electronic devices 301a and 301b (e.g., ...). Figure 1 Input module 150 or Figure 3The wearable electronic devices 301a and 301b acquire ambient sound through microphone 350. When the ambient sound listening function is activated, the wearable electronic devices 301a and 301b can output the ambient sound acquired through microphone 350 via output device 360. In this case, the wearable electronic devices 301a and 301b can control output device 360 ​​to position the sound image in a first direction to notify the user that the sound is output from the first direction. After activating the ambient sound listening function according to the above method, when the wearable electronic device 301 rotates back to the designated area corresponding to the first direction within a specified time, the wearable electronic devices 301a and 301b can deactivate the ambient sound listening function. The designated area can be an area based on the first direction and a designated value. For example, when the designated value is 45 degrees, the wearable electronic devices 301a and 301b can set the area formed by 45 degrees to the right and 45 degrees to the left along the first direction as the designated area. In this case, the wearable electronic devices 301a and 301b can stop outputting ambient sound.

[0071] When the rotation angle indicating the degree of rotation is less than a specified value, wearable electronic devices 301a and 301b may not activate the ambient sound listening function. When the ambient sound listening function is not activated, wearable electronic devices 301a and 301b may output only sound, not ambient sound. In this case, wearable electronic devices 301a and 301b can control the sound image to be positioned in a first direction to provide the user with immersive sound output from the first direction. According to an embodiment, wearable electronic devices 301a and 301b position the sound image in a second direction in which the user is looking, so that the user can perceive the sound being output from the second direction in which the user is looking.

[0072] Traditional wearable electronic devices can only continuously output the sound of the image, even when the user rotates their head to observe the surrounding environment while viewing the reproduced image on the screen. Wearable electronic devices 301a and 301b according to various embodiments of the present invention can activate an ambient sound listening function when the user rotates their head to observe the surrounding environment. For example, when a user wearing wearable electronic devices 301a and 301b rotates their head by a predetermined angle or greater, wearable electronic devices 301a and 301b can activate the ambient sound listening function.

[0073] At the same time, Figure 2In the illustration, wearable electronic devices 301a and 301b are shown as wireless in-ear headphones, but the technical concept of this disclosure is not limited to this. For example, wearable electronic devices 301a and 301b can be implemented as headphones (e.g., a headphone device) or other types of sound output devices.

Figure 2 (301a) and wearable electronic devices worn on the user's right ear ( Figure 2 Any one of (301b). In this case, other wearable electronic devices 301a or 301b can be implemented in the same or similar manner as wearable electronic device 301. Alternatively, wearable electronic device 301 can be implemented as a headset device. According to an embodiment, electronic device 201 can be implemented as a smartphone or tablet PC.

[0085] According to an embodiment, processor 220 can send a control signal to wearable electronic device 301 to activate the ambient sound listening function of wearable electronic device 301 based on the degree of rotation of wearable electronic device 301. According to an embodiment, processor 320 can perform the operation of activating the ambient sound listening function through output device 360 ​​based on the control signal.

[0086] According to an embodiment, the processor 320 can perform its operations independently without a control signal from the electronic device 201. For example, even when not based on a control signal received from the electronic device 201, the processor 320 can activate the ambient sound listening function based on the degree of rotation of the wearable electronic device 301.

[0087] According to an embodiment, microphone 350 can acquire ambient sound. According to an embodiment, output device 360 ​​can be implemented as a speaker. According to an embodiment, output device 360 ​​may include a first channel for outputting sound based on signals received from electronic device 201 and a second channel for outputting ambient sound of wearable electronic device 301. The first channel and the second channel may refer to different channels. According to an embodiment, processor 320 can output sound through the first channel and output ambient sound of wearable electronic device 301 through the second channel.

[0088] First, it is described that the processor 320 is implemented to activate the ambient sound listening function based on the degree of rotation of the wearable electronic device 301, even when not based on a control signal received from the electronic device 201.

[0089] According to an embodiment, wearable electronic device 301 can be communicatively connected to electronic device 201. According to an embodiment, electronic device 201 can communicate via display 260 (e.g., ...). Figure 3 The display 260 can reproduce content (e.g., movies, music, or videos) or make call connections to external electronic devices. According to an embodiment, the electronic device 201 can send content- or call-based signals (e.g., voice signals) to the wearable electronic device 301 via the communication module 290.

[0090] According to an embodiment, the processor 320 can output sound based on a signal of first intensity via the output device 360.

[0091] According to an embodiment, while outputting sound at a first intensity, the processor 320 can identify a first orientation of the wearable electronic device 301 worn by the user via the sensor 376. According to an embodiment, the first orientation may refer to the frontal orientation of the user wearing the wearable electronic device 301 or the direction along which the user wearing the wearable electronic device 301 faces the electronic device 201. Alternatively, the processor 320 can identify the first orientation via the sensor 376 before outputting sound. According to an embodiment, the processor 320 can output notification information via the output device 360 ​​to cause the user wearing the wearable electronic device 301 to face forward or towards the electronic device 201 for a specified period of time. According to an embodiment, the processor 220 can output notification information via the display 260 to cause the user wearing the wearable electronic device 301 to face forward or towards the electronic device 201.

[0092] According to an embodiment, when the processor 320 detects, via the sensor 376, that the device has been looking in a specific direction for a specified time, that specific direction can be determined as a first direction. According to an embodiment, the processor 320 can use the sensor 376 to detect whether the wearable electronic device 301 has rotated from the first direction. The first direction can be determined as 0 degrees.

[0093] According to an embodiment, when the wearable electronic device 301 rotates to a second direction, the processor 320 can identify a first sense value corresponding to a rotation angle indicating the degree of rotation between the first and second directions. According to an embodiment, the second direction can refer to a rightward, leftward, upward, or downward direction from the first direction.

[0094] According to an embodiment, the processor 320 can identify whether the rotation angle indicating the degree of rotation is greater than a first specified value. According to an embodiment, the first specified value may refer to the rotation angle used to determine whether to activate the ambient sound listening function. The first specified value may be set by the processor 320 or by the user. For example, the first specified value may be 45 degrees. For example, the processor 320 can identify that the wearable electronic device 301 has rotated 30 degrees to the right from a first direction. For example, the processor 320 can identify that the wearable electronic device 301 has rotated 30 degrees to the left from a first direction. For example, the processor 320 can identify that the wearable electronic device 301 has rotated 30 degrees upward from a first direction. For example, the processor 320 can identify that the wearable electronic device 301 has rotated 30 degrees downward from a first direction.

[0095] According to an embodiment, when the rotation angle indicated by the first sensing value is not greater than a first specified value, the processor 320 can identify or determine that the user wearing the wearable electronic device 301 is facing forward or towards the electronic device 201. According to an embodiment, the processor 320 can continuously output sound only at a first intensity through the output device 360 ​​based on determining that the user is facing forward or towards the electronic device 201.

[0096] According to an embodiment, when the rotation angle indicated by the first sensing value is greater than a first specified value, the processor 320 can activate the ambient sound listening function.

[0097] According to an embodiment, when it is detected that the rotation angle indicated by the first sensing value is greater than a first specified value, and when it is detected that the wearable electronic device 301 faces the second direction for a first specified time from the time when the rotation angle indicated by the first sensing value is greater than the first specified value, the processor 320 can activate the ambient sound listening function. According to an embodiment, the first specified time may refer to the time during which the processor 320 determines whether to activate the ambient sound listening function. The first specified time may be set by the user or by the processor 320.

[0098] According to an embodiment, when the rotation angle indicated by the first sensing value is greater than a first specified value and the wearable electronic device 301 is detected to be facing the second direction more than a specified number of times, the processor 320 can activate the ambient sound listening function. According to an embodiment, the specified number of times may refer to the number of times the processor 320 determines whether to activate the ambient sound listening function. The specified number of times may be set by the user or by the processor 320.

[0099] According to an embodiment, when the wearable electronic device 301 is detected to have rotated from a first direction to a third direction by the sensor 376, the processor 320 can identify a second sensing value corresponding to the rotation angle between the first direction and the third direction. According to an embodiment, when the wearable electronic device 301 is detected to be facing the third direction more than a specified number of times, the processor 320 can activate the ambient sound listening function even when the rotation angle indicated by the second sensing value is less than a first specified value.

[0100] According to an embodiment, when the wearable electronic device 301 is detected to be moving towards a third direction at a speed greater than a specified speed, the processor 320 can activate the ambient sound listening function even when the rotation angle indicated by the second sensing value is less than the first specified value.

[0101] According to an embodiment, when the ambient sound listening function is activated, the processor 320 can output the ambient sound of the wearable electronic device 301 obtained through the microphone 350 while simultaneously outputting sound through the output device 360. According to an embodiment, the processor 320 can output sound at a second intensity. According to an embodiment, the second intensity can be less than the first intensity. According to an implementation, the first intensity and the second intensity can be the same. For example, when a call is connected to an external electronic device, the processor 320 can output a call-based sound intensity at a second intensity less than the first intensity. For example, when reproducing content, the processor 320 can output a content-based sound intensity at a second intensity less than the first intensity.

[0102] According to an embodiment, when the ambient sound listening function is activated, the processor 320 can output ambient sound through the output device 360 ​​without outputting sound. According to an embodiment, when the ambient sound listening function is activated, the processor 320 can stop reproducing content. According to an embodiment, the processor 320 can stop outputting sound based on the cessation of content reproduction.

[0103] According to an embodiment, when a spatial audio function based on head tracking technology is executed, the processor 320 can control the output device 360 ​​such that the sound image of the sound output through the output device 360 ​​is positioned in a first direction. According to an embodiment, the processor 320 can control the output device 360 ​​such that the sound image is positioned in the first direction, regardless of the magnitude of the rotation angle between the first and second directions. For example, even when the wearable electronic device 301 rotates from the first direction to the right, the user wearing the wearable electronic device 301 can perceive that the sound is output from the user's left side. Therefore, the wearable electronic device 301 can provide the user with the effect of sound output from the first direction. According to an embodiment, when the wearable electronic device 301 rotates to the second direction such that the rotation angle from the first direction is greater than a first specified value, the processor 320 can control the output device 360 ​​such that the sound image of the ambient sound is positioned in the second direction. According to an embodiment, the user wearing the wearable electronic device 301 can perceive that the sound is output from the first direction and that the ambient sound of the wearable electronic device 301 is output from the second direction. According to an embodiment, the wearable electronic device 301 can more realistically transmit ambient sound to the user by positioning the sound image of the ambient sound in a second direction facing the user. According to an embodiment, the wearable electronic device 301 can control the output device 360 ​​so that the sound image of the ambient sound is positioned at the user's location. For example, the user can perceive the ambient sound emanating from the user's body (e.g., head). However, this is an example, and according to various embodiments of the invention, the wearable electronic device 301 can position the sound image of the ambient sound at different locations.

[0104] According to an embodiment, when the wearable electronic device 301 is detected to have rotated to a second direction and the rotation angle indicated by the first sensing value is less than a first specified value, the processor 320 can control the output device 360 ​​so that the sound image of the sound output through the output device 360 ​​is positioned in the second direction. According to an embodiment, the processor 320 can provide sound to the user more realistically by positioning the sound image of the sound in the second direction facing the user. According to an embodiment, when the wearable electronic device 301 is detected to have rotated to a second direction and the rotation angle indicated by the first sensing value is greater than the first specified value, the processor 320 can control the output device 360 ​​so that the sound image of the sound output through the output device 360 ​​is positioned in the first direction. In this case, the processor 320 can control the output device 360 ​​so that the sound image of the ambient sound is positioned in the second direction. According to an embodiment, the wearable electronic device 301 can transmit ambient sound to the user more realistically by positioning the sound image of the ambient sound in the second direction facing the user. According to an embodiment, the wearable electronic device 301 can control the output device 360 ​​so that the sound image of the ambient sound is positioned at the user's location. For example, a user can perceive ambient sounds emanating from their body (e.g., head). According to an embodiment, wearable electronic device 301 can provide a user with an environment where they can focus on ambient sounds by controlling output device 360 ​​such that the position of the ambient sound's sound image differs from the position of the sound's sound image.

[0105] According to an embodiment, when the wearable electronic device 301 is detected to have rotated back to a designated area corresponding to the first direction within a second specified time period from the time the ambient sound listening function is activated via the output device 360 ​​(e.g., the time of outputting ambient sound), the processor 320 may stop outputting ambient sound. The designated area may be an area based on the first direction and a first specified value. For example, when the first specified value is 45 degrees, the processor 320 may determine the first direction as 0 degrees and set the area formed by 45 degrees to the left and 45 degrees to the right of the first direction as the designated area. Alternatively, the designated area may refer to the area formed by 45 degrees upward and 45 degrees downward of the first direction. The second specified time may be set by the user or by the processor 320. The second specified time may be different from or the same as the first specified time.

[0106] According to an embodiment, if the wearable electronic device 301 does not rotate back to the designated area corresponding to the first direction within a second specified time from the time the ambient sound listening function is activated (e.g., the time of outputting ambient sound), the processor 320 may not stop outputting ambient sound. According to an embodiment, if the wearable electronic device 301 rotates back to the designated area corresponding to the first direction after the second specified time from the time the ambient sound listening function is activated, the processor 320 may stop the output of ambient sound based on a separate user input for stopping the output of ambient sound. According to an implementation, when the wearable electronic device 301 rotates back to the designated area corresponding to the first direction after the second specified time, the processor 320 may stop outputting ambient sound. Therefore, the wearable electronic device 301 can provide the user with an environment where the user can focus on and listen to sounds relevant to the content.

[0107] According to an embodiment, processor 320 can be implemented to perform operations by receiving control signals from electronic device 201. For example, processor 320 can send control signals to wearable electronic device 301 to output ambient sound according to the degree of rotation of wearable electronic device 301. According to an embodiment, wearable electronic device 301 can send sensor values ​​or changes in sensor values ​​obtained by sensor 376 to electronic device 201 via communication module 390, and receive control signals from electronic device 201 for activating the ambient sound listening function. According to an embodiment, processor 320 can perform the operation of outputting ambient sound based on the control signals.

[0108] According to an embodiment, while the wearable electronic device 301 outputs sound at a first intensity, the processor 220 can obtain the first orientation of the wearable electronic device 301 worn by the user through the communication module 290. According to an embodiment, the processor 220 can obtain the first orientation before the wearable electronic device 301 outputs sound. According to an embodiment, the processor 220 can output notification information via the display 260 to instruct the user wearing the wearable electronic device 301 to face forward or towards the electronic device 201.

According to an embodiment, the processor 220 can obtain sensing values ​​from the wearable electronic device 301 in real time and identify whether the wearable electronic device 301 has faced a specific direction for a specified time. According to an embodiment, the processor 220 can periodically obtain sensing values ​​from the wearable electronic device 301 via the communication module 290 and identify whether the wearable electronic device 301 has been facing a specific direction for a specified period of time. According to an embodiment, the processor 220 can determine this specific direction as a first direction.

Figure 3 The direction along which the content on the monitor (260) is viewed or the direction forward.

[0193] According to embodiments, wearable electronic devices 301a and 301b can perform spatial audio functions based on head tracking technology. The spatial audio function based on head tracking technology refers to the function of controlling the position of the sound image to be positioned in the first direction even when the head of a user wearing wearable electronic devices 301a and 301b rotates from a first direction to a specific direction. When the spatial audio function based on head tracking technology is performed, the user wearing wearable electronic devices 301a and 301b can perceive sound output from the first direction. For example, the user wearing wearable electronic devices 301a and 301b can perceive sound output from the front direction before rotating their head. The user wearing wearable electronic devices 301a and 301b can perceive sound output from the user's left side after rotating their head to the right.

[0194] According to an embodiment, sensor 376 can identify whether the rotation angle between the first and second directions is greater than a first specified value when wearable electronic devices 301a and 301b rotate to the second direction. For example, the first specified value can be 45 degrees.

[0195] According to an embodiment, when the rotation angle (e.g., 30 degrees) between the first and second directions is detected to be less than a first specified value, wearable electronic devices 301a and 301b may not activate their ambient sound listening functions. According to an embodiment, each of the wearable electronic devices 301a and 301b can be connected via an output device 360 ​​(e.g., ...). Figure 3 The output device 360 ​​only outputs sound images in the direction of the first direction. Therefore, wearable electronic devices 301a and 301b can provide users with information about the sound output from the first direction.

[0196] According to the implementation, when the rotation angle (e.g., 30 degrees) between the first and second directions is detected to be less than a first specified value, the wearable electronic devices 301a and 301b can position the sound in the second direction by outputting the sound image through the output device 360. Therefore, the wearable electronic devices 301a and 301b can provide the user with immersive sound output from the second direction currently viewed by the user.

[0197] refer to Figure 13 (b) According to an embodiment, wearable electronic devices 301a and 301b can detect a rotation angle of 90 degrees between the first direction and the second direction via sensor 376. When the detected rotation angle (e.g., 90 degrees) between the first direction and the second direction is greater than a first specified value (e.g., 45 degrees), wearable electronic devices 301a and 301b can activate the ambient sound listening function.

[0198] According to an embodiment, when the ambient sound listening function is activated, wearable electronic devices 301a and 301b can output ambient sound simultaneously with the output sound. The direction in which the wearable electronic devices 301a and 301b can output the sound image is positioned relative to the ambient sound in a second direction. Therefore, an immersive output of ambient sound from the second direction can be provided to the user. According to an embodiment, wearable electronic device 301 can control the output device 360 ​​such that the sound image of the ambient sound is positioned at the user's location (e.g., the position of the user's head). For example, the user can perceive the ambient sound being output from the user's body (e.g., head). However, this is an example, and the wearable electronic devices 301a and 301b of embodiments of the present invention can control the positioning of the sound image of the ambient sound at various locations or directions.

[0199] According to an embodiment, wearable electronic devices 301a and 301b can recognize that they have rotated back to a designated area corresponding to a first direction since the ambient sound listening function was activated. For example, the designated area may be a region formed by 45 degrees to the right and 45 degrees to the left relative to 0 degrees. According to an embodiment, when wearable electronic devices 301a and 301b rotate back to the designated area corresponding to the first direction, they can deactivate the ambient sound listening function.
