     BACKGROUND 
     Field 
     The disclosure relates to an operation control method and an electronic device thereof, for example, for controlling an operation mode of another electronic device. 
     Description of Related Art 
     Various electronic devices, such as a smartphone, a tablet PC, a portable multimedia player (PMP), a personal digital assistant (PDA), a laptop personal computer, or a wearable device, are being widespread. 
     An electronic device may output sound data using a wearable electronic device such as an earphone or a headset. The electronic device may be connected to an earphone or a headset in a wireless communication method (e.g., Bluetooth), and may transmit/receive a variety of control information to output sound data to the earphone or headset. 
     A wireless earphone device or a wireless speaker may be inserted near the ear canal of the user&#39;s ear, or may be worn to be positioned between the outside of the user and the user&#39;s eardrum in a form that completely covers the ear, so that the user may be unable to hear an external sound while wearing the wireless earphone device or the wireless speaker. 
     When no external sound is introduced into the wearable electronic device such as the earphone and/or headset, the user can enjoy a higher quality sound in an immersed manner, but it may be difficult for the user to properly respond to an external situation when no external sound is introduced. 
     A wearable device such as an earphone and/or a headset needs to be controlled according to circumstances so that a sound can be enjoyed without an external sound being introduced or a user&#39;s response is possible when an external sound is introduced. 
     SUMMARY 
     Embodiments of the disclosure provide an electronic device that may control a wearable electronic device so that the external sound of the wearable electronic device may or may not be introduced based on the operating state of the electronic device. 
     An electronic device according to various example embodiments of the disclosure may include: a memory, a communication module comprising communication circuitry configured to communicate with an external electronic device, and a processor operatively connected to the memory and the communication module, wherein the processor may be configured to: identify whether the external electronic device is in a worn state through the communication module, and transmit a control command through the communication module to change an audio output mode of the external electronic device based on an operating state of the electronic device being changed according to a command stored in the memory so that a designated condition is satisfied to thereby control an operation of the external electronic device according to the designated condition. 
     A method of operating an electronic device according to various example embodiments of the disclosure may include: identifying whether an external electronic device is in a worn state, identifying whether a designated condition is satisfied according to a change in an operating state of the electronic device, and transmitting a control command to change an audio output mode of the external electronic device and monitoring an operation of the external electronic device based on the designated condition being satisfied. 
     According to various example embodiments, it is possible to control an external sound to be introduced or not to be introduced through a wearable device such as an earphone and/or a headset based on the operating state of the electronic device, so that the user can enjoy a sound in an immersed manner by preventing and/or reducing the external sound from being introduced according to the operating state of the electronic device, or the user can appropriately respond to an external situation by allowing the external sound to be introduced. 
     According to various example embodiments, it is possible to configure the operating state of the electronic device for controlling an external sound to be introduced or not to be introduced through a wearable device such as an earphone and/or a headset, so that the operation of the wearable device may be controlled according to a condition configured for each user.

     According to an embodiment, one (e.g., the first electronic device  210 ) of the external electronic devices  210  and/or  220  may serve as a primary to communicate with the electronic device  101 , and the other (e.g., the second electronic device  220 ) of the external electronic devices  210  and/or  220  may serve as a secondary to communicate with the first electronic device  210  which is the primary electronic device. In an embodiment, when each of the first electronic device  210  and the second electronic device  220  is implemented as an earbud, the first electronic device  210  may be referred to as a primary earbud or primary equipment (PE), and the second electronic device  220  may be referred to as a secondary earbud or secondary equipment (SE). For example, the first electronic device  210  may communicate with the electronic device  101  through the first communication link  201  as the primary, and the second electronic device  220  may communicate with the first electronic device  220  through the second communication link  202  as the secondary. In this case, a third communication link  203  between the second electronic device  220  and the electronic device  101  may be in an idle state and/or in an unconnected state. For example, as the secondary electronic device, the second electronic device  220  may sniff the first communication link  201  between the first electronic device  210  and the electronic device  101  to acquire data transmitted from the electronic device  101  to the first electronic device  210 . 
     Hereinafter, a case in which the first electronic device  210  among the external electronic devices  210  and/or  220  is communicably connected to the electronic device  101  through the first communication link  201  as the primary electronic device in the initial operation to transmit/receive data and the second electronic device  220  sniffs the first communication link  201  as the secondary to acquire data will be described as an example. In this case, the third communication link  203  with the electronic device  101  may be in an idle state and/or in an unconnected state. 
     According to an embodiment, the first electronic device  210  as the primary may allow the second electronic device  220  to operate as the primary to be communicably connected to the electronic device  101  through the third communication link  203  by a role switch with the second electronic device  220  as the secondary. For example, the first electronic device  210  may switch its role to the secondary (slave) to communicate with the primary second electronic device  220  through the second communication link  202 , and may acquire data transmitted from the electronic device  101  to the second electronic device  220  through sniffing on the third communication link  203 . For example, the second electronic device  210  that has switched its role to the secondary may switch the first communication link  201  with the electronic device  101  into an idle state and/or a non-connected state. 
       FIG.  3    is a block diagram illustrating an example configuration of an electronic device  300  (e.g., the first electronic device  210  or the second electronic device  220  of  FIG.  2   ) according to various embodiments.

     The processor  320  may include various processing circuitry and execute, for example, software (e.g., a program) to process a control command and/or audio data received from an electronic device (e.g., the electronic device  101  of  FIG.  2   ) connected through the communication circuit  310 , and may store information according to the processing result or information generated according to the operation of various components in the memory  330  or transmit the information to other electronic devices (e.g., the electronic device  101 , the first electronic device  210 , and/or the second electronic device  220 ). To this end, the processor  320  may control at least one other component (e.g., hardware or software component) of the electronic device  300  and may process or operate a variety of data. 
     The memory  330  may store a variety of data used by at least one component (e.g., the processor  320  or the sensor  360 ) of the electronic device  300 . The data may include, for example, input data or output data for software (e.g., a program) and commands related thereto. The memory  330  may include a volatile memory or a nonvolatile memory. 
     According to an embodiment, as at least a part of data processing or operation, the processor  320  may load commands or data received from another component (e.g., the sensor  360  or the communication circuit  310 ) into the volatile memory, may process the commands or data loaded into the volatile memory, and may store the resultant data in the nonvolatile memory. 
     The communication circuit  310  may support establishment of a communication channel through a communication link (e.g., the first communication link  201 , the second communication link  202 , or the third communication link  203 ) between the electronic device  300  and the electronic device  101  or between the electronic device  300  and another electronic device (e.g., the second electronic device  220  or the first electronic device  210 ), and/or may support communication performance through the established communication channel. 
     According to an embodiment, the communication circuit  310  may include a wireless communication module (e.g., a cellular communication module, a local area wireless communication module, or a global navigation satellite system {GNSS} communication module) or a wired communication module. 
     According to an embodiment, the communication circuit  310  may communicate with the electronic device  101  through the first communication link  201  and the third communication link  203  (e.g., a local area wireless communication network such as Bluetooth, Wi-Fi direct, or infrared data association {IrDA}). 
     According to an embodiment, the communication circuit  310  may communicate with another electronic device (e.g., the second electronic device  220 ) through the second communication link  202  (e.g., a local area wireless communication network such as Bluetooth, Wi-Fi direct, or infrared data association {IrDA}). 
     According to an embodiment, the communication circuit  310  may include an antenna module. The antenna module of the communication circuit  310  may transmit or receive a signal and/or power to or from the outside (e.g., the electronic device  101 ). According to an embodiment, the antenna module of the communication circuit  310  may include one antenna including a radiator including a conductor or a conductive pattern provided on a substrate (e.g., a PCB). 
     According to an embodiment, the antenna module may include a plurality of antennas. In this case, among the plurality of antennas, at least one antenna suitable for a communication scheme used in a wireless communication network such as the first communication link  301 , the second communication link  302 , and/or the third communication link  303  may be selected by the communication circuit  310 . The signal or power may be transmitted or received between the communication circuit  310  and an external electronic device (e.g., the sound source electronic device  101 ) through the selected at least one antenna. According to various embodiments, another component (e.g., an RFIC) other than the radiator may be additionally provided as a portion of the antenna module. 
     According to an embodiment, the sensor  360  may include a contact or grip sensor, an acceleration sensor, and/or a gyro sensor, but is not limited thereto. The contact or grip sensor may detect, when the electronic device  300  is brought into a contact with, for example, the user&#39;s ear for a designated time period or more and/or a designated intensity or more, this contact, and may transmit a sensor signal to the processor  320 . The acceleration sensor and/or the gyro sensor may detect motion and/or inertia of the electronic device  300 . The acceleration sensor and/or the gyro sensor may include a circuit (e.g., an integrated circuit {IC}) for controlling the operation of the acceleration sensor and/or the gyro sensor. For example, the circuit (e.g., an integrated circuit {IC}) for controlling the operation of the acceleration sensor and/or the gyro sensor may be included in the electronic device  300  and may be implemented as the processor  320 . 
     According to an embodiment, the processor  320  may determine whether the electronic device  300  is worn based on a sensor value obtained from the contact or grip sensor, the acceleration sensor, and/or the gyro sensor of the sensor  360 , and may transmit, to the electronic device  101 , a signal indicating that the electronic device is worn when it is determined that the electronic device  300  is worn. 
     According to an embodiment, the speaker  350  may output an audio signal to the outside of the electronic device  300 . The processor  320  may output an electrical signal (audio signal) processed based on the audio data received from the wirelessly connected electronic device  101  as a sound through the speaker  350 . 
     The microphone  340  may convert a sound obtained from the outside into an electrical signal. The sound introduced into the microphone  340  may include, for example, the sound of the speaker  350  reflected from the inside of the user&#39;s external auditory meatus in addition to the sound generated in the user&#39;s external environment when the electronic device  300  is worn. 
     According to an embodiment, the processor  320  may mix and output the sound acquired from the microphone  340  and the audio data received from the electronic device  101  according to the audio output mode of the electronic device  300 . For example, when the audio output mode is an ambient sound canceling mode, the processor  320  may mute the sound acquired from the microphone  340  and may output only an audio signal converted from the audio data through the speaker  350 . For example, when the audio output mode is the ambient sound listening mode, the processor  320  may mix the sound acquired from the microphone  340  and the audio signal converted from the audio data, and may output the mixed data through the speaker  350 . The processor  320  may change or maintain the audio output mode to the ambient sound canceling mode or the ambient sound listening mode based on an audio mode control command received from the electronic device  101  through the communication circuit  310 . As another example, the processor  320  may transmit information according to the processing result of the control command received from the electronic device  101  to the electronic device  101 . 
     Although not illustrated, the electronic device  300  may include a battery for supplying power required for each component. The electronic device  300  may further include a power management circuit (not illustrated) for controlling charging of the battery using power supplied from an external power source and managing power supplied to each component. The battery may include, for example, a non-rechargeable primary cell, a rechargeable secondary cell, and/or fuel cell. 
       FIG.  4    is a flowchart illustrating an example operation of an electronic device (e.g., the electronic device  101  of  FIG.  1  or  2   ) for controlling an operation of an external electronic device (e.g., the electronic device  300  of  FIG.  3   ) according to various embodiments. 
     According to an embodiment, the external electronic device  300  may include a headphone, an earphone, and/or an earbud, or the like, which can be worn on the user and provide a sound to the user based on audio data received from the electronic device  101  through a communication function. Hereinafter, an example in which the external electronic device  300  is implemented as a wearable electronic device such as an earbud will be described, but various embodiments may not be limited thereto. 
     According to various embodiments, the electronic device  101  may include a portable and/or movable electronic device such as a smartphone, a tablet PC, a portable multimedia player (PMP), a personal digital assistant (PDA), a laptop PC, and a wearable device. 
     According to various embodiments, the electronic device  101  may be an electronic device capable of reproducing music or videos, and accordingly, may provide audio data processed by an audio module (e.g., the audio module  170  of  FIG.  1   ) to the external electronic device  300 . 
     According to various embodiments, the electronic device  101  may be connected to the external electronic device  300  using a local area wireless communication network such as Bluetooth (or BLE), Wi-Fi direct, or infrared data association (IrDA) to transmit audio data or a variety of control information including a control command. The electronic device  101  may receive information on confirmation of reception and processing results and/or information on the operating state from the external electronic device  300 . 
     According to an embodiment, in operation  401 , a processor (e.g., the processor  120  of  FIG.  1   ) of the electronic device  101  may confirm whether the external electronic device  300  is in a worn state. 
     According to an embodiment, the processor  120  may be connected to the external electronic device  300  through the communication module  190  to receive a signal for confirming whether the external electronic device  300  is in a worn state from the external electronic device  300 . For example, the processor  120  may receive, from the external electronic device  300 , related information for confirming whether the external electronic device  300  is in a worn state based on a sensor signal of a sensor (e.g., the sensor  360  of  FIG.  3   ) of the external electronic device  300 . For example, the processor  320  of the external electronic device  300  may establish a connection with the electronic device  101  through a wireless communication network as the external electronic device  300  is activated, and may transmit, to the electronic device  101 , information indicating that the external electronic device  300  is worn based on the sensor signal received through the sensor  360  as the external electronic device  300  is worn on the user. 
     According to an embodiment, the processor  120  of the electronic device  101  may be connected to the external electronic device  300  through a communication module (e.g., the communication module  190  of  FIG.  1   ) by instructions stored in a memory (e.g., the memory  130  of  FIG.  1   ), for example, using local area wireless communication such as Bluetooth. When allocating communication resources in communication with the external electronic device  300  through the communication module  300  using local area wireless communication such as Bluetooth, the processor  120  may relatively assign a processing priority to a control command for switching an audio output mode. For example, in allocating communication resources, the processor  120  may relatively assign a priority to the control command for switching the audio output mode compared to the audio data. Accordingly, the control command for switching the audio output mode may be transmitted to the external electronic device  300  without delay. Meanwhile, when the communication resource is allocated, the processor  120  may allow the audio data to be streamed without delay by assigning a relatively lower priority to control information excluding the control command for switching the audio output mode, compared to the audio data. 
     According to an embodiment, in operation  403 , the processor  120  of the electronic device  101  may monitor the operating state of the electronic device  101  when the external electronic device  300  is in a worn state to determine whether a designated condition is satisfied. 
     According to an embodiment, the processor  120  of the electronic device  101  may store information on a designated condition for the operating state of the electronic device  101  in a memory (e.g., the memory  130  of  FIG.  1   ), and may monitor the operating state of the electronic device  101  to determine whether the designated condition is satisfied. 
     According to an embodiment, the designated condition for the operating state of the electronic device  101  may include information indicating whether at least one application and/or component is activated or operated. For example, the designated condition may include a case in which at least one application and/or component in which a user&#39;s utterance can be expected or a user&#39;s response according to the user&#39;s recognition is requested is activated and operated. For example, the designated condition may include activation of a near field communication (NFC) tag and/or a magnetic secure transmission (MST) tag application in which tagging and confirmation thereof are required. For example, the designated condition may include a case in which an application for simple payment authentication that requires user&#39;s fingerprint recognition and/or password authentication is activated. For example, the designated condition may include a case in which a recording application requiring user&#39;s recognition or response and/or a photographing application are executed. 
     For example, the designated condition may include a case in which the activation of at least one application and/or component in which a user&#39;s utterance can be expected or a user&#39;s recognition is requested or a user&#39;s response is required as described above is terminated and the operation is terminated. 
     According to an embodiment, the designated condition may be configured in advance in the electronic device  101  or may be configured by the user. For example, the processor  120  of the electronic device  101  may display a screen for configuring a condition for changing an operation mode of the external electronic device  300  on a display (e.g., the display module  160  of  FIG.  1   ) according to a user input, which will be described later in detail. 
     According to an embodiment, when the designated condition is satisfied, in operation  405 , the processor  120  may transmit a control command requesting a change in the audio output mode for the external electronic device  300  to the external electronic device  300 . 
     According to an embodiment, the audio output mode of the external electronic device may include an ambient noise canceling mode to which, for example, active noise cancellation (ANC) technology is applied, and/or an ambient sound listening mode in which the ANC technology is not applied or an external sound introduced through the microphone (e.g., the microphone  340  of  FIG.  3   ) of the external electronic device  300  is output through the speaker  350 . The name used for the ambient sound canceling mode or the ambient sound listening mode is merely an example. The ambient sound canceling mode may include an operation mode in which various technologies are applied to increase the immersion in the audio signal output by blocking sounds introduced from the outside except for the audio signal generated by the audio data, and the ambient sound listening mode may include an operation mode that does not block the sounds introduced from the outside and may further include an operation mode in which the sound introduced from the outside is output through the speaker  350  at least a certain volume or more together with the audio signal. For example, in a case in which an activation condition of at least one application and/or component in which a user&#39;s utterance can be expected in the electronic device  101 , a user&#39;s recognition is requested, or a user&#39;s response is required is satisfied, an audio output mode change command for changing the ambient sound canceling mode to the ambient sound listening mode may be transmitted to the external electronic device  300 . 
     According to an embodiment, according to the audio output mode change command transmitted from the electronic device  101 , the external electronic device  300  may change the audio output mode from the ambient sound canceling mode to the ambient sound listening mode or from the ambient sound listening mode to the ambient sound canceling mode. For example, in the case in which an activation condition of at least one application and/or component in which a user&#39;s utterance can be expected in the electronic device  101 , a user&#39;s recognition is requested, or a user&#39;s response is required is satisfied, as the audio output mode change command for changing the ambient sound canceling mode to the ambient sound listening mode is transmitted from the electronic device  101  to the external electronic device  300 , the audio output mode of the external electronic device  300  may be changed to the ambient sound listening mode correspondingly. For example, in a case in which an activation termination condition of at least one application and/or component in which a user&#39;s utterance can be expected in the electronic device  101 , a user&#39;s recognition is requested, or a user&#39;s response is required is satisfied, as the audio output mode change command for changing the ambient sound listening mode to the ambient sound canceling mode is transmitted from the electronic device  101  to the external electronic device  300 , the audio output mode of the external electronic device  300  may be changed to the ambient sound canceling mode accordingly. 
     According to an embodiment, the external electronic device  300  may change the audio output mode from the ambient sound listening mode to the ambient sound canceling mode according to a user input. For example, when a touch input (e.g., a long touch or a double touch) to the external electronic device  300  is generated, the audio output mode may be changed from the current mode to another mode. For example, when the touch input to the external electronic device  300  is generated, the audio output mode may be changed from the ambient sound listening mode to the ambient sound canceling mode. As another example, after the audio output mode for the external electronic device  300  is changed to the ambient sound canceling mode, when a touch input is generated again, the audio output mode may be changed from the ambient sound canceling mode to the ambient sound listening mode. 
     According to an embodiment, the electronic device  300  may mix the sound acquired from the microphone  340  with the audio data received from the electronic device  101  according to the audio output mode, or may mute or output the sound acquired from the microphone  340 . For example, when the audio output mode is the ambient sound canceling mode, the processor  320  may reverse the phase of wave with respect to the sound acquired from the microphone  340  and may output the resultant data through the speaker  350 , thereby causing destructive interference with respect to the sound acquired from the microphone  340  to block ambient sounds and allowing the user to focus on the audio signal. For example, when the audio output mode is the ambient sound listening mode, the electronic device  300  may mix the sound acquired from the microphone  340  and the audio signal converted from the audio data, and may output the mixed data through the speaker  350 . 
     According to an embodiment, the electronic device  300  may store the currently operating audio output mode in the memory  330  according to the change in the audio output mode. 
     According to an embodiment, in operation  407 , the processor  120  of the electronic device  101  may monitor the audio output mode of the external electronic device  300 . 
     According to an embodiment, the processor  120  of the electronic device  101  may transmit/receive a variety of information through communication with the external electronic device  300 , and may receive information on the processing result according to a change command of the operation mode from the external electronic device  300 . For example, the processor  120  may receive information indicating that the audio output mode has been changed according to the command change of the audio output mode to the external electronic device  300 . For example, the processor  120  may receive information indicating that the audio output mode changed according to the audio output mode change command of the external electronic device  300  is operating. 
     According to an embodiment, the external electronic device  300  may detect a user&#39;s voice utterance using an acceleration sensor and/or the microphone  340  of a sensor (e.g., the sensor  360  of  FIG.  3   ), and may operate to change the audio output mode to the ambient sound listening mode or maintain the ambient sound listening mode when the voice utterance is detected. When the audio output mode is changed, the external electronic device  300  may notify the electronic device  101  of the mode change. 
     According to an embodiment, the external electronic device  300  may be implemented to operate a timer at a time point when the audio output mode is changed to the ambient sound listening mode according to the control of the electronic device  101  and/or at a time point when it is determined that the audio output mode is changed to the ambient sound listening mode or the audio output mode is maintained according to a user&#39;s utterance, and to maintain the ambient sound listening mode for a designated time. For example, the timer for maintaining the ambient sound listening mode may be configured as time required to maintain the activation of the at least one application and/or component in which a user&#39;s utterance can be expected, a user&#39;s recognition is requested, or a user&#39;s response is required. 
     According to an embodiment, when the external electronic device  300  terminates the ambient sound listening mode according to the expiration of the timer, the external electronic device  300  may notify the electronic device  101  of the termination of the ambient sound listening mode. Accordingly, the electronic device  101  may confirm that the above-described condition is satisfied and confirm the termination of the ambient sound listening mode of the external electronic device  300 , or may transmit a control command for maintaining the ambient sound listening mode to the external electronic device  300 . 
     According to an embodiment, the processor  120  may transmit a request for identifying the current operation mode or operating state of the external electronic device  300  periodically or if necessary, and may receive a response thereto from the external electronic device  300 . 
     According to an embodiment, the processor  120  may display information on a change in the operation mode and/or the current operation mode of the external electronic device  300  on a display (e.g., the display module  160  of  FIG.  1   ). 
       FIGS.  5 ,  6  and  7    are diagrams illustrating examples of an operation of an electronic device (e.g., the electronic device  101  of  FIG.  1   ) for controlling an operation of an external electronic device (e.g., the electronic device  300  of  FIG.  3   ) according to various embodiments. 
       FIG.  5    illustrates an example of a screen of a display for configuring an operating state condition of the electronic device  101  for changing a current operation mode to an ambient sound listening mode for the external electronic device  300  according to a setting function. 
     An ambient sound listening mode setting screen of  FIG.  5    may provide a selection button  501  for enabling or disabling an ambient sound listening mode function. 
     According to an embodiment, the ambient sound listening mode setting screen may provide a voice detection selection button  505  for enabling the ambient sound listening mode to be activated as the user&#39;s utterance is detected when the ambient sound listening mode is used. In a case of using the ambient sound listening mode, the electronic device  101  may control the audio output mode of the external electronic device  300  to be changed to the ambient sound listening mode when the user&#39;s utterance is detected. 
     According to an embodiment, when the ambient sound listening mode is used, as a designated application is activated, the ambient sound listening mode setting screen may provide an app execution detection selection button  507  to activate the ambient sound listening mode. According to this, in a case in which the ambient sound listening mode is used, the electronic device  101  may control the audio output mode of the external electronic device  300  to be changed to the ambient sound listening mode when the execution of one of the designated applications is detected. 
     According to an embodiment, the ambient sound listening mode setting screen may include a detailed setting button  503  for providing a more detailed configuration menu. 
       FIG.  6    illustrates a detailed setting screen for an ambient sound listening mode target application provided according to the selection of the detailed setting button  503  of  FIG.  5   . 
     Referring to  FIG.  6   , the detailed setting screen may provide a list of selectable applications so that the external electronic device  300  changes the audio output mode to the ambient sound listening mode when an application configured for various applications is executed. For example, the detailed setting screen may provide a selection button  601  for a payment application (e.g., Samsung Pay app), a selection button  605  for a recording application (e.g., a voice recording app), and/or a selection button  607  for an image taking application (e.g., a camera app). As an example, the displayed application may be provided through the detailed setting screen so that various applications capable of being executed in the electronic device  101  can be included in a condition for changing the audio output mode of the external electronic device  300  to the ambient sound listening mode. 
     In  FIG.  7   , a setting screen for configuring the volume of audio data and ambient sound may be displayed in the ambient sound listening mode provided according to the selection of the detailed setting button  503  of  FIG.  5   . 
     Referring to  FIG.  7   , a volume setting screen may provide a sound bar  701  for configuring the volume of an audio signal and a sound bar  705  for configuring the volume of an ambient sound. For example, when the volume is not configured separately, the external electronic device  300  may mix an audio signal and an ambient sound signal and may output the mixed signal through a speaker (e.g., the speaker  350  of  FIG.  3   ) so that the audio volume and ambient sound volume are configured to be heard at a level of 50:50 by default. For example, when the volume is configured to a volume of 30 for the audio volume sound bar  701  and a volume of 70 for the sound bar  705  of the ambient sound volume, the audio signal and the ambient sound signal may be mixed and output the mixed signal through the speaker  350  so that the audio volume and the ambient sound volume are configured to be heard at a level of 30:70 according to the settings. 
       FIG.  8    is a signal flow diagram illustrating an example operation of an electronic device (e.g., the electronic device  101  of  FIG.  1  or  2   ) for controlling the operation of an external electronic device (e.g., the external electronic device  210  or  220  of  FIG.  2    or the external electronic device  300  of  FIG.  3   ) according to various embodiments. 
     According to an embodiment, the external electronic device  300  may include a headphone, an earphone, and/or an earbud, or the like, capable of being worn on the user and providing a sound to the user based on audio data received from the electronic device  101  through a communication function. Hereinafter, an example in which the external electronic device  300  is implemented as a wearable electronic device such as an earbud will be described, but various embodiments may not be limited thereto. 
     According to various embodiments, the electronic device  101  may include, for example, and without limitation, a portable and/or movable electronic device such as a smartphone, a tablet PC, a portable multimedia player (PMP), a personal digital assistant (PDA), a laptop PC, a wearable device, or the like. 
     According to various embodiments, the electronic device  101  may be an electronic device capable of reproducing music or videos, and accordingly, may provide audio data processed by an audio module (e.g., the audio module  170  of  FIG.  1   ) to the external electronic device  300 . 
     According to various embodiments, the electronic device  101  may be connected to the external electronic device  300  using a local area wireless communication network such as Bluetooth (or BLE), Wi-Fi direct, or infrared data association (IrDA) to transmit audio data or a variety of control information including a control command. The electronic device  101  may receive information on confirmation of reception and processing results and/or information on the operating state from the external electronic device  300 . 
     According to an embodiment, in operation  801 , the external electronic device  300  may detect the wearing of the external electronic device  300 . For example, the external electronic device  300  may detect whether the external electronic device  300  is worn on the user&#39;s ear based on a sensor signal of a sensor (e.g., the sensor  360  of  FIG.  3   ) including a proximity sensor, a grip sensor, and/or an acceleration sensor. 
     According to an embodiment, in operation  803 , the external electronic device  300  may notify the electronic device  101  of detection of the wearing of the external electronic device  300 . For example, as the external electronic device  300  is activated, the external electronic device  300  may establish a connection with the electronic device  101  through a wireless communication network, and may transmit, to the electronic device  101 , information indicating that the external electronic device  300  is worn based on the sensor signal received through the sensor  360  as the external electronic device  300  is worn on the user. 
     According to an embodiment, the electronic device  101  may be connected to the external electronic device  300  through a communication module (e.g., the communication module  190  of  FIG.  1   ), and may receive the wearing detection signal from the external electronic device  300 . 
     According to an embodiment, in operation  831 , the electronic device  101  may adjust a priority for communication resource allocation in wireless communication in order to give a priority to a control command for a mode change for the external electronic device  300 . For example, the electronic device  101  may be connected to the external electronic device  300  through a communication module using local area wireless communication such as Bluetooth communication, and may assign a processing priority for the control command for switching the audio output mode when allocating the communication resource in communication with the external electronic device  300  through the communication module  190 . For example, in allocating communication resources, the electronic device  101  may relatively assign a priority to the control command for switching the audio output mode in allocating the communication resources, compared to the audio data. Accordingly, the control command for switching the audio output mode may be transmitted to the external electronic device  300  without delay. Meanwhile, when the communication resource is allocated, the electronic device  101  may allow the audio data to be streamed without delay by assigning a relatively lower priority to control information excluding the control command for switching the audio output mode, compared to the audio data. 
     In general, when the external electronic device  300  to which active noise cancellation (ANC) technology is applied is worn, it may be difficult to hear an ambient sound because the ambient sound is shielded. Accordingly, when a wearer&#39;s utterance is detected using a microphone or a vibration sensor, a function of switching to the ambient sound listening mode may be provided. However, even in this case, since the ambient sound listening mode is activated only when the wearer speaks, ambient sounds such as words from the other party or warning sounds from the surroundings are shielded before the wearer speaks and the wearer cannot hear the ambient sounds, so that it may be difficult to determine the corresponding situation. For example, the user may not be able to hear the ambient sound at the time of the other party&#39;s conversation during simple payment, a tapping sound when using a transportation card, or in a situation where photographing or recording is taking place. 
     According to an embodiment, in operation  833 , when the external electronic device  300  is in a worn state, the operating state of the electronic device  101  may be monitored to determine whether a designated condition for entering the ambient sound listening mode is satisfied. 
     According to an embodiment, the electronic device  101  may identify information on the designated condition for entering the ambient sound listening mode for the operating state of the electronic device  101  from a memory (e.g., the memory  130  of  FIG.  1   ), and may determine whether the condition is satisfied by monitoring the operating state of the electronic device  101  based on the identified information. 
     According to an embodiment, the designated condition for the operating state of the electronic device  101  may include various cases in which the activation condition of at least one application and/or component in which a wearer&#39;s utterance of the external electronic device  300  can be expected in the electronic device  101 , a wearer&#39;s recognition is requested, or a wearer&#39;s response is required is satisfied. For example, the designated condition may include activation of a near field communication (NFC) tag and/or a magnetic secure transmission (MST) tag application for which tagging and confirmation thereof are required. For example, the designated condition may include a case in which an application for simple payment authentication that requires user&#39;s fingerprint recognition and/or password authentication is activated. For example, the designated condition may include a case in which a recording application and/or a photographing application requiring user&#39;s recognition or response are executed. 
     According to an embodiment, according to the designated condition for the operating state of the electronic device  101  for entering the ambient sound listening mode, even before the wearer&#39;s utterance of the external electronic device  300 , by responding in advance to situations in which it is necessary or expected to listen to ambient sounds, the wearer may listen to the ambient sounds and determine the situation. 
     According to an embodiment, in operation  835 , when the designated condition is satisfied, the electronic device  101  may transmit a control command for allowing an audio output mode for the external electronic device  300  to be changed to an ambient sound listening mode, to the external electronic device  300 . 
     According to an embodiment, the ambient sound listening mode of the external electronic device  300  may include an operation mode in which sounds introduced from the outside are not blocked and further include an operation in which the sounds introduced from the outside are output through the speaker  350  at least a predetermined volume or higher together with an audio signal. 
     According to an embodiment, in operation  805 , according to an audio output mode change command transmitted from the electronic device  101 , the external electronic device  300  may store the current audio output mode. For example, when the current audio output mode is the ambient sound canceling mode, the fact that the ambient sound canceling mode is operating may be stored, and the electronic device may return to the ambient sound canceling mode, which is the current audio output mode, when a situation required to return to the ambient sound canceling mode occurs. 
     According to an embodiment, in operation  807 , the external electronic device  300  may notify the electronic device  101  of a change in the audio output mode of the external electronic device  300 . For example, the external electronic device  300  may notify the electronic device  101  that the audio output mode is changed to the ambient sound listening mode as a result of processing the audio output mode change command of the electronic device  101 . 
     According to an embodiment, in operation  837 , the electronic device  101  may display, for example, a change in the audio output mode of the external electronic device  300  on a display (e.g., the display module  160  of  FIG.  1   ). 
     According to an embodiment, in operation  809 , the external electronic device  300  may change the audio output mode to the ambient sound listening mode. 
     According to an embodiment, the external electronic device  300  may mix and output a sound acquired from the microphone  340  and audio data received from the electronic device  101  according to the ambient sound listening mode. For example, the external electronic device  300  may mix the sound acquired from the microphone  340  and the audio signal converted from the audio data, and may output the resultant data through the speaker  350 . 
     According to an embodiment, in operation  811 , the external electronic device  300  may detect a user&#39;s voice utterance using an acceleration sensor and/or the microphone  340  of a sensor (e.g., the sensor  360  of  FIG.  3   ), and may change the audio output mode to the ambient sound listening mode or maintain the ambient sound listening mode when the voice utterance is detected. 
     According to an embodiment, in operation  813 , when the wearer&#39;s utterance is not detected, the external electronic device  300  may start the operation of a delay timer. For example, by operating the delay timer, the electronic device  300  may maintain the ambient sound listening mode for a predetermined period of time even when the wearer&#39;s utterance is not detected, and may terminate the ambient sound listening mode when the wearer&#39;s utterance is not continuously detected for a predetermined period of time. 
     According to an embodiment, the external electronic device  300  may operate a timer at a point in time when the audio output mode is changed to the ambient sound listening mode and/or at a time point when it is determined to change the audio output mode to the ambient sound listening mode or maintain the ambient sound listening mode according to the wearer&#39;s utterance, or may operate the timer at a time point when the user&#39;s utterance is last detected to maintain the ambient sound listening mode for at least a predetermined period of time. For example, the timer for maintaining the ambient sound listening mode may be configured as time required to maintain the activation of the at least one application and/or component in which a user&#39;s utterance can be expected, a user&#39;s recognition is requested, or a user&#39;s response is required. 
     According to an embodiment, in operation  839 , the electronic device  101  may determine whether a condition for terminating the ambient sound listening mode as the audio output mode of the external electronic device  300  is satisfied, and may transmit a command for terminating an ambient sound listening mode to the external electronic device  300  in operation  841  when the condition is satisfied. 
     According to an embodiment, a condition for terminating the ambient sound listening mode of the external electronic device  300  may include various cases in which an activation condition of at least one application and/or component in which the wearer&#39;s utterance can be expected, the wearer&#39;s recognition is requested, or the wearer&#39;s response is required is satisfied. For example, the condition for terminating the ambient sound listening mode may include termination of use of a near field communication (NFC) tag and/or a magnetic secure transmission (MST) tag application requiring tagging and confirmation thereof. For example, the condition for terminating the ambient sound listening mode may include a case in which payment is completed according to an application for simple payment authentication that requires user&#39;s fingerprint recognition and/or password authentication. For example, the condition for terminating the ambient sound listening mode may include a case in which a recording application and/or a photographing application requiring user&#39;s recognition or response is terminated. 
     According to an embodiment, in operation  815 , the external electronic device  300  may determine whether the timer expires or the command for terminating the ambient sound listening mode is received from the electronic device  101 . 
     According to an embodiment, when the timer expires or the command for terminating the ambient sound listening mode is received, the external electronic device  300  may return to the previous mode (e.g., the ambient sound listening mode) in operation  817 , and may notify the electronic device  101  of the return in operation  819  when the ambient sound listening mode is terminated. 
     According to an embodiment, the electronic device  101  may display information on the change in the operation mode and/or the current operation mode of the external electronic device  300  on the display in operation  843 . 
     According to an example embodiment, an electronic device (e.g., the electronic device  101  of  FIG.  1   ) may include: a memory (e.g., the memory  130  of  FIG.  1  or  2   ), a communication module comprising communication circuitry (e.g., the communication module  190  of  FIG.  1   ) configured to communicate with an external electronic device (e.g., the external electronic device  210 ,  220 , and/or  330  of  FIG.  2  or  3   ), and a processor operatively connected to the memory and the communication module, wherein the processor may be configured to: confirm that the external electronic device is in a worn state through the communication module, and transmit a control command through the communication module to change an audio output mode of the external electronic device based on an operating state of the electronic device being changed according to an instruction stored in the memory so that a designated condition is satisfied, to thereby control the operation of the external electronic device according to the designated condition. 
     According to an example embodiment, the processor may be configured to control the communication module to assign a priority to resource allocation for transmitting the control command for changing the audio output mode of the external electronic device. 
     According to an example embodiment, the audio output mode may include an ambient sound listening mode in which an ambient sound is introduced through a speaker of the external electronic device and an ambient sound canceling mode in which the ambient sound is canceled.
