FIG. 1 illustrates an operating environment of an output device according to an embodiment of the disclosure.
Referring to FIG. 1, an audio output device 100 may include a first output device 101 and a second output device 102. For example, the first output device 101 may be mounted on one ear of a user, and the second output device 102 may be mounted on the other ear of the user. In an embodiment, the first output device 101 may communicate with an external electronic device 10 and the second output device 102. The audio output device 100 may operate in association with the external electronic device 10, and may operate standalone.
According to an embodiment, the external electronic device 10 may be one of various mobile devices such as a smartphone, a tablet personal computer (PC), a smart watch, or the like. The external electronic device 10, for example, may output a voice received from any other electronic device during a phone call, a sound source stored in the external electronic device 10 or a sound source being streamed in real time through a communication network, a sound generated upon playing at least one content, or the like. In an embodiment, the voice or the sound source may be transmitted to the audio output device 100, and may be output by the audio output device 100. The audio output device 100 may include the first output device 101 and the second output device 102. The first output device 101 and the second output device 102 are illustrated in FIG. 1 as being kernel-type earphones, but a type of the first output device 101 and the second output device 102 is not limited thereto. For example, the first output device 101 and the second output device 102 may be open-type earphones. Below, a configuration of the first output device 101 will be described with reference to FIG. 1.
According to an embodiment, the first output device 101 may include a wingtip 111, an ear tip 121, a speaker 131, a heart rate (HR) sensor 141, and a terminal 151. The wingtip 111 may be coupled on the periphery of the first output device 101 so as to be replaceable. For example, the wingtip 111 may have elasticity, and may help the first output device 101 to be closely mounted on user's ear. The wingtip 111 may form the exterior of the first output device 101. The ear tip 121 may be coupled at one end of the first output device 101. The ear tip 121 may be, for example, a cylindrical shape. The ear tip 121 may have elasticity, and may help the first output device 101 to be closely mounted on user's ear. The speaker 131 may be positioned within a housing of the first output device 101. The sound output by the speaker 131 may be transferred to user's eardrum through a hollow of a tip. The HR sensor 141 may be positioned within the housing of the first output device 101. When the first output device 101 is mounted on user's ear, the HR sensor 141 may measure a heartbeat of the user by using at least one light emitting unit which may output a light in a specified wavelength range. For example, the at least one light emitting unit may include at least one of an infrared (IR) light emitting unit, a red light emitting unit, a green light emitting unit, a blue light emitting unit, or a white light emitting unit. The first output device 101 may determine whether the first output device 101 is worn by the user, based on the data measured by the HR sensor 141. The terminal 151 may be electrically connected with a charging device, and a battery (not illustrated) of the first output device 101 may be charged through the terminal 151.
The configuration of the first output device 101 illustrated in FIG. 1 is exemplary, and at least a part of the first output device 101 having the configuration illustrated in FIG. 1 may be omitted or replaced. As described above, according to an embodiment, the first output device 101 may be an open earphone. For example, the first output device 101 may not include the wingtip 111. For another example, the first output device 101 may include a speaker, at least a portion of which is exposed, on one surface of the first output device 101 instead of the ear tip 121.
According to an embodiment, the first output device 101 may be wirelessly connected with the external electronic device 10. The first output device 101 may be connected with the external electronic device 10 by wireless communication (e.g., Bluetooth or Bluetooth low energy (BLE)). The first output device 101 may be connected with the external electronic device 10 through a hands-free profile (HFP) or an advanced audio distribution profile (A2DP). In the case where the first output device 101 is connected with the external electronic device 10 through the HFP, the external electronic device 10 may be set to an HFP audio gateway (AG), and the first output device 101 may be set to an HFP hands-free unit (HF). In the case where the first output device 101 is connected with the external electronic device 10 through the A2DP, the external electronic device 10 may be set to an A2DP source (SRC), and the first output device 101 may be set to an A2DP sink (SNK).
According to an embodiment, the first output device 101 may be wirelessly connected with the second output device 102. The first output device 101 may be connected with the second output device 102 by wireless communication (e.g., Bluetooth or BLE). For example, the first output device 101 may be connected with the second output device 102 through the HFP or A2DP. In this case, the first output device 101 may operate as a master, and the second output device 102 may operate as a slave. An example is illustrated in FIG. 1 as the first output device 101 operates as a master and the second output device 102 operates as a slave, but the disclosure is not limited thereto. For example, the second output device 102 may operate as a master, and the first output device 101 may operate as a slave. According to an embodiment, each of the first output device 101 and the second output device 102 may operate as a master. For example, the first output device 101 and the second output device 102 may operate independently of each other. The first output device 101 and the second output device 102 may operate independently of the external electronic device 10.
According to an embodiment, the first output device 101 may be wirelessly connected with the second output device 102. When connected with the external electronic device 10, the first output device 101 may receive audio data associated with a voice or a sound source. The first output device 101 may receive the audio data in a streaming manner and may output the received audio data through the speaker 131. The first output device 101 may transmit the received audio data to the second output device 102. The first output device 101 may output a sound source stored in the first output device 101 or the second output device 102. In this case, the first output device 101 may not be connected with the external electronic device 10. According to an embodiment, the second output device 102 may include a wingtip 112, an ear tip 122, a microphone hole 162, and a touch pad 172. The wingtip 112 and the ear tip 122 of the second output device 102 may be identical to the wingtip 111 and the ear tip 121 of the first output device 101. Although not illustrated in FIG. 1, the second output device 102 may include a speaker, an HR sensor, and a terminal which are identical to those of the first output device 101. Also, although not illustrated in FIG. 1, the first output device 101 may include a microphone hole and a touch pad which are identical to those of the second output device 102.
According to an embodiment, the microphone hole 162 may be formed at a housing of the second output device 102. A microphone may be positioned below the microphone hole 162, and a sound may be transferred to the microphone through the microphone hole 162 from the outside.
According to an embodiment, the touch pad 172 may be formed at a location where the touch pad 172 is exposed when the second output device 102 is inserted into user's ear. The touch pad 172 may sense a contact of user's body. When a touch input is sensed by the touch pad 172, for example, the second output device 102 may perform a function, which corresponds to the touch input, such as play, stop, fast-forward, rewind, volume control, call connection, call end, or the like.
According to various embodiments, the external electronic device 10 may obtain data which are sensed by sensors included in the first output device 101 and the second output device 102. For example, the external electronic device 10 may obtain data sensed by the first output device 101 and data sensed by the second output device 102 through the first output device 101. For another example, the external electronic device 10 may obtain data from each of the first output device 101 and the second output device 102.
According to an embodiment, the external electronic device 10 may identify objects associated with the first output device 101 and the second output device 102, based on a result of comparing the obtained data. For example, the external electronic device 10 may determine whether a first object (e.g., a user which utilizes the first output device 101) and a second object (e.g., a user which utilizes the second output device 102) are different from each other. For example, the external electronic device 10 may determine whether the audio output device 100 is used by a plurality of users. For example, the external electronic device 10 may determine whether the audio output device 100 is used by a plurality of users, by comparing data sensed by the first output device 101 and data sensed by the second output device 102.
According to an embodiment, the external electronic device 10 may control the audio output device 100 based on the data sensed by the first output device 101 and the second output device 102. For example, the external electronic device 10 may control the first output device 101 and the second output device 102 in an associated state or in an independent state. For example, when it is determined that the first object associated with the first output device 101 and the second object associated with the second output device 102 are different from each other, the external electronic device 10 may control the first output device 101 and the second output device 102 so as to operate independently of each other. For another example, when it is determined that the audio output device 100 is used by a plurality of users, the external electronic device 10 may allow the first output device 101 and the second output device 102 to operate independently of each other.
According to an embodiment, the external electronic device 10 may control the audio output device 100 through communication with the audio output device 100. For example, the external electronic device 10 may control the first output device 101 and the second output device 102 by transmitting a signal to the first output device 101 or the second output device 102. In this case, the external electronic device 10 may transmit a signal to a master device of the audio output device 100. For another example, the external electronic device 10 may control the first output device 101 and the second output device 102 by transmitting a signal to the first output device 101 and the second output device 102. In this case, each of the first output device 101 and the second output device 102 may operate as a master device.
According to an embodiment, the external electronic device 10 may set a state of the audio output device 100 through communication with the audio output device 100. For example, the external electronic device 10 may control states of the first output device 101 and the second output device 102 by transmitting a signal to the first output device 101 or the second output device 102. In this case, the external electronic device 10 may transmit a signal to a master device of the audio output device 100. For another example, the external electronic device 10 may control states of the first output device 101 and the second output device 102 by transmitting a signal to the first output device 101 and the second output device 102. In this case, each of the first output device 101 and the second output device 102 may operate as a master device.
According to an embodiment, depending on an operation state of the audio output device 100, the external electronic device 10 may provide information about operation states of the first output device 101 and the second output device 102 or a user interface for controlling the first output device 101 and the second output device 102. For example, when it is determined that the first object associated with the first output device 101 and the second object associated with the second output device 102 are different from each other or when it is determined that the audio output device 100 is used by a plurality of users, the external electronic device 10 may provide, on a display, user interfaces which may control the first output device 101 and the second output device 102 individually. According to an embodiment, the first output device 101 and the second output device 102 may be associated with different applications. For example, the external electronic device 10 may display, on the display, a user interface corresponding to an application associated with the first output device 101 and a user interface corresponding to an application associated with the second output device 102.
According to an embodiment, based at least on information sensed by the first output device 101 and the second output device 102, the external electronic device 10 may set the first output device 101 or the second output device 102 to a master device and may set the other device to a slave device. Also, the external electronic device 10 may provide a notification to the master device. For example, the notification may be associated with a call or a message to the external electronic device 10. For another example, the notification may be associated with an operation state of the audio output device 100.
According to various embodiments, at least a part of the above-described operations of the external electronic device 10 may be performed by the first output device 101. For example, the first output device 101 may obtain data which are sensed by sensors included in the first output device 101 and the second output device 102. For example, the first output device 101 may identify objects associated with the first output device 101 and the second output device 102, by comparing data sensed by the first output device 101 and data sensed by the second output device 102. For example, the first output device 101 may determine whether a first object (e.g., a user which utilizes the first output device 101) and a second object (e.g., a user which utilizes the second output device 102) are different from each other. For example, the first output device 101 may determine whether the audio output device 100 is used by a plurality of users. For example, the first output device 101 may determine whether the audio output device 100 is used by a plurality of users, by comparing data sensed by the first output device 101 and data sensed by the second output device 102. According to an embodiment, the first output device 101 may control the audio output device 100 based on the data sensed by the first output device 101 and the second output device 102. For example, the first output device 101 may control the first output device 101 and the second output device 102 so as to operate in an associated state or in an independent state. Also, the above-described operations may be performed by the second output device 102. Below, exemplary embodiments will be more fully described with reference to FIGS. 2 to 13.

FIGS. 4A and 4B are views for describing how to determine whether an audio output device is worn by a plurality of users, according to an embodiment of the disclosure.
Referring to FIGS. 4A and 4B, an external electronic device 40 may communicate with a first output device 401 and a second output device 402. For example, the external electronic device 40, the first output device 401, and the second output device 402 may correspond to the external electronic device 10, the first output device 101, and the second output device 102 illustrated in FIG. 1. An example is illustrated in FIGS. 4A and 4B as the external electronic device 40 communicates with the first output device 401, but the external electronic device 40 may communicate with the second output device 402 or may communicate with the first output device 401 and the second output device 402.
According to an embodiment, the first output device 401 may receive information sensed by the second output device 402. For example, the first output device 401 may determine operation states of the first output device 401 and the second output device 402 based at least on information sensed by the first output device 401 and information sensed by the second output device 402.
According to an embodiment, the first output device 401 may determine an operation state based on biometric information (e.g., heartbeat information). Referring to FIG. 4A, the same heartbeat information (e.g., a heart rate, a heartbeat timing, a heartbeat interval, a heartbeat waveform, and/or a heartbeat frequency) is sensed by the first output device 401 and the second output device 402. In this case, the first output device 401 may determine that the first output device 401 and the second output device 402 are used by the same user. Referring to FIG. 4B, different heartbeat information is sensed by the first output device 401 and the second output device 402. In this case, the first output device 401 may determine that the first output device 401 and the second output device 402 are used by different users.
According to another embodiment, the first output device 401 may determine an operation state based on non-biometric information (e.g., an output direction and/or a distance). For example, referring to FIG. 4A, the first output device 401 and the second output device 402 may face the same point. In this case, the first output device 401 may determine that the first output device 401 and the second output device 402 are used by the same user. Referring to FIG. 4B, the first output device 401 and the second output device 402 may face different points. In this case, the first output device 401 may determine that the first output device 401 and the second output device 402 are used by different users. For example, the first output device 401 may determine directions in which the first output device 401 and the second output device 402 face, based on angular velocity and/or acceleration information of the first output device 401 and the second output device 402 obtained by using sensing modules (e.g., the sensing module 251 of FIG. 2 and the sensing module 252 of FIG. 2) of the first output device 401 and the second output device 402. For another example, returning to FIG. 4A, in the case where the first output device 401 is spaced from the second output device 402 by a specified distance or more, the first output device 401 may determine that the first output device 401 and the second output device 402 are used by different users. For example, the first output device 401 may determine a distance between the first output device 401 and the second output device 402, based at least on an intensity of a communication signal or a response speed through communication circuits (e.g., the communication circuit 261 of FIG. 2 and the communication circuit 262 of FIG. 2) of the first output device 401 and the second output device 402.
According to an embodiment, when it is determined that the first output device 401 and the second output device 402 are used by different users, the first output device 401 may transmit information corresponding to the use by the plurality of users to the external electronic device 40.
In the above embodiments, a description is given as whether the first output device 401 and the second output device 402 are used by the same user is determined by the first output device 401, but whether the first output device 401 and the second output device 402 are used by the same user may be determined by the external electronic device 40. For example, the external electronic device 40 may receive information sensed by the first output device 401 and the second output device 402 through the first output device 401. For another example, the external electronic device 40 may receive information sensed by the first output device 401 from the first output device 401 and may receive information sensed by the second output device 402 from the second output device 402.
The operation states of the first output device 401 and the second output device 402 may be determined as described above. Below, a method in which an electronic device displays an operation state based on determining the operation state will be described with reference to FIG. 5.
FIG. 5 is a view illustrating a method in which an electronic device displays an operation state of an audio output device, according to an embodiment of the disclosure.
Referring to FIG. 5, according to an embodiment, an electronic device 50 (e.g., the external electronic device 10 of FIG. 1) may display operation state information indicating an operation state of an external audio output device (e.g., the audio output device 100 of FIG. 1) in at least a portion on a display 58 (e.g., the display device 360 of FIG. 3). For example, the electronic device 50 may display the operation state information in a first display area 580 on the display 58.
According to an embodiment, the electronic device 50 may display the operation state information by using at least one of an image, a character, an icon, or a pop-up message. For example, when the operation state information is changed, the electronic device 50 may display the changed operation state information on the display 58 by using a pop-up message. For example, the operation state information may be information indicating whether the external audio output device is used by a plurality of users.
According to an embodiment, the electronic device 50 may display an operation state of an external audio device on a first display area 580 (e.g., a task bar, an indicator, or a notification bar) by using at least one icon. For example, in the case where the external audio device is connected (e.g., paired) with the electronic device 50, the electronic device 50 may display a first icon 581 (e.g., a Bluetooth icon) indicating a connection of the external audio device in the first display area 580. Also, in the case where the external audio output device is used by a plurality of users, the electronic device 50 may display a change of the operation state of the external audio output device on the first display area 580. For example, the electronic device 50 may display a second icon 582 changed from the first icon 581 on the first display area 580. For another example, the electronic device 50 may display a third icon 583 or a fourth icon 584 indicating operation state information corresponding to a plurality of users on the first display area 580 together with the first icon 581.
Meanwhile, shapes of the icons illustrated in FIG. 5 are exemplary, and icon shapes are not limited thereto. Also, according to an embodiment, the electronic device 50 may notify a change of an operation state through a visual, auditory, and/or tactile notification.
The notification method according to a change of the operation state of the external audio output device is described with reference to FIG. 5. As described above, in the case where an external audio output device is used by different users (e.g., in the case where the external audio output device is used by a plurality of users), a first output device (e.g., the first output device 101 of FIG. 1) and a second output device (e.g., the second output device 102 of FIG. 1) of the external audio output device may operate independently of each other. Below, an independent control method of an external audio output device according to an operation state will be described with reference to FIGS. 6A and 6B.
FIG. 6A illustrates a user interface for an independent volume control of an audio output device, according to an embodiment of the disclosure.
Referring to FIG. 6A, according to an embodiment, an electronic device 60 (e.g., the external electronic device 10 of FIG. 1) may display a user interface for controlling an operation of an external audio output device (e.g., the audio output device 100 of FIG. 1) in at least a portion on a display 68 (e.g., the display device 360 of FIG. 3). For example, in the case where the external audio output device is used by a plurality of users, the electronic device 60 may display a user interface 680 for controlling the external audio output device in a specified area (or a partial area) on the display 68. For example, in the case where the external audio output device is used by a plurality of users, the electronic device 60 may display the user interface 680 including a first user interface for controlling a first output device of the external audio output device and a second user interface for controlling a second output device of the external audio output device in a specified area (or a partial area) on the display 68.
According to an embodiment, a user interface may be an interface for adjusting an output volume of the external audio output device. For example, when a user input for adjusting an output volume is received, the electronic device 60 may display the user interface 680 on the display 68. For example, the user input for adjusting the output volume of the external audio output device may be received through the electronic device 60 or the external audio output device.
According to an embodiment, the electronic device 60 may display the user interface 680 at a specified location of the display 68. For example, the electronic device 60 may display the user interface 680 on the top, the center, or the bottom of the display 68. For another example, the electronic device 60 may display the user interface 680 at a location on the display 68, which is adjacent to a physical button for a volume control of the electronic device 60.
FIG. 6B illustrates an independent volume control of an audio output device, according to an embodiment of the disclosure.
According to an embodiment, referring to FIG. 6B, a first output device 601 (e.g., the first output device 101 of FIG. 1) and a second output device 602 (e.g., the second output device 102 of FIG. 1) of an external audio output device 600 (e.g., the audio output device 100 of FIG. 1) may include a first touch sensor 671 and a second touch sensor 672, respectively. For example, a first user input 691 may correspond to an input for a volume control received by the first output device 601, and a second user input 692 may correspond to an input a volume control received by the second output device 602. However, the first touch sensor 671 and the second touch sensor 672 are exemplary input devices, and input devices of the first output device 601 and the second output device 602 are not limited thereto. For another example, the first output device 601 may include a first input device, and the second output device 602 may include a second input device. For example, the first input device and the second input device may include at least one button (e.g., a button which may receive a push input, a roll input, a scroll input, and/or a toggle input). According to an embodiment, an independent volume control may be performed based on whether the first output device 601 and the second output device 602 are used by the same user. For example, depending on whether the first output device 601 and the second output device 602 are used by the same user, different operations may be performed in response to the first user input 691 and the second user input 692.
According to an embodiment, the first output device 601 and the second output device 602 may be used by the same user. For example, each of the first output device 601 and the second output device 602 may adjust a volume of the external audio output device 600. For example, referring to FIG. 6A, the electronic device 60 may display only one scroll bar for a volume control in a specified area (or a partial area) on the display 68. For another example, the first output device 601 may adjust a volume of the external audio output device 600 in response to the first user input 691 and may change a sound source to be played in response to the second user input 692.
According to an embodiment, returning to FIG. 6B, the first output device 601 and the second output device 602 may be used by different users. For example, the first output device 601 may adjust a volume of the first output device 601 in response to the first user input 691. For another example, the second output device 602 may adjust a volume of the second output device 602 in response to the second user input 692. For example, referring to FIG. 6A, when the first user input 691 or the second user input 692 is received, the electronic device 60 may display two scroll bars for respectively adjusting volumes of the first output device 601 and the second output device 602 on the user interface 680.
Embodiments associated with a volume control are described with reference to FIGS. 6A and 6B. However, an independent control of the first output device 601 and the second output device 602 is not limited thereto. For example, an output mode (e.g., a stereo mode or a mono mode), an output characteristic, and/or an independent sound source control of the first output device 601 and the second output device 602 may be applied to the first output device 601 and the second output device 602. Below, various embodiments associated with an independent control will be described with reference to FIGS. 7, 8, 9A, and 9B.

FIG. 10 illustrates a master device setting method, according to an embodiment of the disclosure.
Referring to FIG. 10, according to an embodiment, an electronic device 1003 (e.g., the external electronic device 10 of FIG. 1) may determine a master device based on heartbeat information of an external electronic device 1004. For example, the external electronic device 1004 may be a wearable device (e.g., a smart watch) which may be mounted on user's body and may include an HR sensor. For example, the external electronic device 1004 may be a device which communicates with the electronic device 1003.

For example, it may be determined that the second heartbeat information of the second output device 1002 and the third heartbeat information of the external electronic device 1004 are identical. In this case, the electronic device 1003 may set the second output device 1002 to a master device. Also, the electronic device 1003 may set the first output device 1001 to a slave device.
According to an embodiment, one output device of the first output device 1001 and the second output device 1002 may be in advance set to a master device.

For example, the first output device 1001, the second output device 1002, and the external electronic device 1004 may obtain biometric information by applying a light having a wavelength in a specified range to a skin of a wearer. For example, the first output device 1001, the second output device 1002, and the external electronic device 1004 may measure biometric information based at least on a current flowing through the skin of the wearer and/or a voltage measured on the skin of the wearer. The electronic device 1003 may set one output device of the first output device 1001 and the second output device 1002 to a master device based on a similarity of the biometric information obtained by the first output device 1001, the second output device 1002, and the external electronic device 1004. For example, the electronic device 1003 may determine a device, which has the highest similarity with the biometric information obtained by the external electronic device 1004 or corresponds to biometric information having a similarity of a specified magnitude or more, from among the first output device 1001 and the second output device 1002 as a master device.
According to an embodiment, the electronic device 1003 may set a master device based at least on a location of the first output device 1001, the second output device 1002, and/or the external electronic device 1004.

For another example, the electronic device 1003 may set an output device, which is out of a specified range from the electronic device 1003 and/or the external electronic device 1004, from among the first output device 1001 and the second output device 1002 to a slave device and may set the other output device to a master device. According to an embodiment, the electronic device 1003 may control the first output device 1001 and the second output device 1002 through the master device.
According to an embodiment, in the case where a notification such as an incoming call or a received message is, the electronic device 1003 may provide the notification only to a master device.

For another example, the electronic device may control the first external audio device and the second external audio device to a state in which the first external audio device is set to operate as a master device and the second external audio device is set to operate as a slave device.
In the case where it is determined that the similarity satisfies the second specified condition, in operation 1120, the electronic device may control the first external audio device and the second external audio device such that the first external audio device and the second external audio device operate independently of each other. For example, the electronic device may control the first external audio device and the second external audio device independently by setting the first external audio device. For another example, the electronic device may control the first external audio device and the second external audio device independently by setting the first external audio device and the second external audio device.
