Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, etc. of a touch object to be touched on the touch screen on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object, which touches the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera 121, a photosensor, and a laser sensor. The camera 121 is a kind of camera sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The power supply unit 190 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components. The power supply unit 190 includes a battery, the battery may be an internal battery configured to be chargeable, and may be detachably coupled to the terminal body for charging or the like.

In addition, the power supply unit 190 may include a connection port, and the connection port may be configured as an example of an interface 160 through which an external charger for supplying power for charging the battery is electrically connected.

As another example, the power supply unit 190 may be configured to charge the battery in a wireless manner without using the connection port. In this case, the power supply unit 190 may use at least one of an inductive coupling method based on a magnetic induction phenomenon from an external wireless power transmission apparatus and a magnetic resonance coupling method based on an electromagnetic resonance phenomenon Power can be delivered.

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

Referring to FIGS. 1B and 1C, the disclosed mobile terminal 100 includes a bar-shaped terminal body. However, the present invention is not limited thereto and can be applied to various structures such as a folder type, a flip type, a slide type, a swing type, and a swivel type in which a watch type, a clip type, a glass type or two or more bodies are relatively movably coupled . A description of a particular type of mobile terminal, although relevant to a particular type of mobile terminal, is generally applicable to other types of mobile terminals.

Here, the terminal body can be understood as a concept of referring to the mobile terminal 100 as at least one aggregate.

Hereinafter, based on sharing audio data between a mobile terminal having the above-described configuration and features and an external device connected to the mobile terminal through a Bluetooth communication method, a sound output from the external device The method of outputting the data will be described in more detail with reference to the accompanying drawings. FIG. 2 is a conceptual diagram for explaining a control method according to an embodiment of the present invention, and FIGS. 3A, 3B and 4 are conceptual diagrams for explaining the control method shown in FIG.

In the mobile terminal according to the present invention, sound output from any one of the terminals can be output from at least one other terminal through data communication between the mobile terminal and the fixed terminal. For example, when music corresponding to a first sound source is reproduced in a first terminal, music corresponding to the first sound source may be reproduced in a second terminal in data communication with the first terminal. Therefore, in the second terminal, even when the sound source is not stored, the sound source can be used through communication with the first terminal.

In this specification, as described above, the function of sharing the sound output from the first terminal with the second terminal is called an 'audio sharing function'. Such an audio sharing function may be replaced by other terms (e. G., "Listening mode "," audio channel mode ", etc.), and it will be apparent that the scope of the technology according to the present invention is not limited by the above terms .

Further, as described above, the audio data shared between the mobile terminals or between the mobile terminal and the fixed terminal to perform an audio sharing function can be shared through a specific communication method. Here, the specific communication method may be a Bluetooth (TM) communication method. Hereinafter, a method of performing the audio sharing function using the Bluetooth communication method will be described in more detail.

For convenience of explanation, a terminal receiving audio data is referred to as a "mobile terminal ". Such a mobile terminal may have the configuration shown in Figs. 1A, 1B, and 1C. The terminal that transmits audio data is referred to as "external device ". Here, the type of the external device is not limited, and the external device can be various kinds of electronic devices supporting the Bluetooth communication mode and the audio sharing function.

In step S210, the mobile terminal searches for an external device capable of Bluetooth communication. Here, searching for an external device may be performed based on the audio sharing function being requested, or even before the audio sharing function is requested. For example, the external device search can be performed corresponding to the Bluetooth communication function being activated. Meanwhile, the search for an external device capable of Bluetooth communication can be performed by the wireless communication unit 110. Hereinafter, although the wireless communication unit 110 is not described in detail, it is obvious that the overall performance of the wireless communication is performed by the wireless communication unit 110. [

Meanwhile, when the external device is searched, the information about the searched external device is output to the display unit 151 of the mobile terminal (S220). Here, the information on the searched external device may be a list of items including identification information of the searched external devices.

Meanwhile, steps S210 and S220 may be performed irrespective of an audio sharing function request. That is, steps S210 and S220 are performed to perform Bluetooth communication with the terminal. Therefore, if steps S210 and S220 are performed before the audio sharing function is requested, at least one of steps S210 and S220 may be omitted even if the audio sharing function request is received.

The mobile terminal can search the external device and receive the identification information of the external device from the searched external device. Here, the identification information may be exchanged even in a state in which no pairing is performed between the mobile terminal and the external device.

Here, "pairing" means a state in which information can be transmitted between the mobile terminal and an external device, that is, a connection is made so as to transmit valid data. In order to perform pairing, an authentication process must be performed between the mobile terminal and the external device. If the external device rejects the pairing, the pairing may not be performed between the external device and the mobile terminal. In addition, if the mobile terminal and any external device have been paired in the past, the authentication process may not be repeated or the authentication information for authentication may be omitted.

On the other hand, the mobile terminal may be in a state that (i) it is paired with all of the searched external devices, (ii) is paired with some of the searched external devices, or (iii) is not paired with all of the searched external devices.

As described above, when a list including information on external devices capable of Bluetooth communication is output and an audio sharing function is requested (S230), the mobile terminal searches for an external device (S240). For example, when an audio sharing function is requested in a state in which a list 200 corresponding to information on an external device capable of Bluetooth communication is output, as shown in FIG. 3A, Among the external devices corresponding to the items included in the list 200, a list 200a including information on external devices that support the audio sharing function is output as shown in (b) of FIG. 3a .

As described above, the request for the audio sharing function may be performed in a state in which an external device is searched and information is output in order to perform Bluetooth communication. Steps S230 and S240 may be applied to this example.

That is, if the request for the audio sharing function is received prior to performing the search for the external device capable of Bluetooth communication, the mobile terminal performs the search for the external device that supports the audio sharing function while enabling Bluetooth communication .

In response to the audio sharing function request, the control unit 180 reselects the external devices that support the audio sharing function among the searched external devices, or refers to the identification information of the external devices previously received to support the audio sharing function It is possible to recognize the external device.

Meanwhile, the audio sharing function request can be made in various ways. For example, as shown in FIG. 3A, an icon associated with the audio sharing function included in the setting screen for Bluetooth communication ) Can be selected.

On the other hand, when a list (200a) containing information of an external device supporting the audio sharing function is outputted and one of the items (for example, yield to "Device C") is selected (S250) The controller 180 may establish a connection for sharing audio data with an external device corresponding to the selected item. The control unit 180 may establish a pairing with an external device corresponding to the item corresponding to the item being selected. Here, the external device that performs the audio sharing function may be referred to as "shared external device ".

In the case where the external device corresponding to the selected item refuses to perform the audio sharing function with the mobile terminal even if any one of the items is selected, the mobile terminal performs an audio sharing function with the external device It may not.

For example, the mobile terminal may transmit a message requesting to perform an audio sharing function to the external device in response to the item being selected. 3B, the external device having received the message outputs guide information indicating that the audio sharing function is requested to the mobile terminal, or receives a message for selecting the user to perform an audio sharing function with the mobile terminal Information (see 310 in Fig. 3B).

Meanwhile, when a sound is output from the external device in a state where the mobile terminal and the external device are connected (S260), audio data for the output sound, that is, audio to be output is transmitted to the mobile device from the external device (S270) . The transmission of the audio data may be carried out in the following manner: i) the sound is transmitted at the same time that the sound is outputted from the external device, ii) it is transmitted before the sound is outputted from the external device, or iii) have.

When the audio data corresponding to the output target sound is received by the mobile terminal in the external device, the mobile terminal outputs a sound corresponding to the output target sound (S280, see Figs. 2 and 3A). Here, the output target sound is received by the mobile terminal from the external device via Bluetooth communication.

According to the i) and iii), the mobile terminal can output the output target sound with a delay and a sound output from the external device. According to the case (ii), the mobile terminal can output the output target sound simultaneously with the sound output from the external device.

More specifically, the audio data may include volume information of the external device in addition to sound data related to the sound. Therefore, in the mobile terminal, based on the volume information included in the audio data, the sound corresponding to the audio data received from the external device can be outputted at a volume equal to or corresponding to the volume set at the external device.

Thus, the audio data includes volume information, and the control unit 180 outputs sound corresponding to the audio data at a volume corresponding to the volume information included in the audio data. Meanwhile, when the volume of the external device is changed, the volume of the sound output from the mobile terminal may be changed to a volume corresponding to the volume changed in the external device. That is, in the external device, the volume information currently set in the external device can be included in the audio data corresponding to the output target sound (or sound corresponding to the audio data to be transmitted to the mobile terminal), and the volume of the external device If changed, the changed volume information can also be included. Therefore, the mobile terminal can output the output target sound at the volume set by the external device based on the audio data.

When a sound is output based on data stored in the mobile terminal, rather than sound corresponding to the audio data received from the external device, the mobile terminal transmits the audio data, not the volume information included in the audio data, It is possible to output a sound at a volume set in the mobile terminal.

That is, the mobile terminal can refer to the volume set by the external device only when a sound corresponding to the audio data received from the external device is output. Further, even when a sound corresponding to the audio data is output, the volume of sound corresponding to the audio data can be changed based on the volume control command in the mobile terminal. The volume control command may be received based on the user's selection.

On the other hand, in the external device, only the sound related to the application or the function corresponding to the predetermined type in the external device can be shared with the mobile terminal. In the external device, only the audio data corresponding to the application or the function corresponding to the predetermined type among the audio data for the output target sound can be selectively transmitted to the mobile terminal. For example, an external device may share a notification tone for a text message when a character is received, but not share a ringing tone when a call is received.

On the other hand, information on whether or not to share a sound may be stored in advance in a memory of an external device or a mobile terminal. Therefore, the external device refers to the information stored in the memory of the external device to share the audio data, or receives information existing in the memory of the mobile terminal, and can transmit the audio data to be shared to the mobile terminal only have.

Further, according to the present invention, since the mobile terminal and the external device share the audio data, even if the mobile terminal is not provided with an application installed in the external device and generating sound for the shared audio data do. For example, in a case where an external device is reproducing a movie through a video player named "A ", and the external device does not have a video player" A " installed in the mobile terminal, To the mobile terminal. Therefore, in the mobile terminal, even if the moving picture player "A" is not installed, the sound of the movie being reproduced can be outputted.

Meanwhile, in the mobile terminal according to the present invention, if audio data is not received from the external device for the reference time, the communication connection for the audio sharing function can be released. In addition, the controller 180 of the mobile terminal may output guidance information indicating that the audio data is not received from the external device before the reference time elapses. Such guide information can be output in any one of auditory, visual, and tactile methods.

On the other hand, an external device can perform an audio sharing function with a plurality of mobile terminals. That is, in the external device, audio data corresponding to the output target sound can be shared with a plurality of mobile terminals.

Also, the mobile terminal can perform an audio sharing function with a plurality of external devices. In this case, when audio data is simultaneously received from a plurality of external devices, the control unit 180 selects a sound corresponding to audio data received from an external device having a higher priority among a plurality of external devices based on a predetermined priority And output it. In this case, the audio data that has not been output may be outputted after the sound corresponding to the audio data having the priority order is output, or may not be outputted.

As described above, according to the present invention, sound reproduced from one terminal can be reproduced in another terminal through audio data sharing among terminals. 4 (a), when the external device 300 corresponds to a TV, the user watches the image through the external device 300, It is possible to listen to the sound corresponding to the image output from the device 300. [

4 (b), when the music is reproduced in the external device 300, when the application related to the music reproduction is not installed in the mobile terminal 100, or when there is no sound source The user can use the music played on the external device 300 through the mobile terminal 100. [

Hereinafter, a method of executing or ending an audio sharing function based on a user selection will be described in detail with reference to the accompanying drawings. 5A, 5B, 6A and 6B are conceptual diagrams for explaining a method of executing or ending the audio sharing function. 3A, an embodiment has been described in which an audio sharing function is requested in a state in which an external device is searched and information is output in order to perform Bluetooth communication. The audio sharing function may be requested in various ways have. That is, in FIG. 3A, after a specific external device to perform an audio sharing function is selected, an external device that supports the audio sharing function is searched, and then a specific external device to perform the audio sharing function is selected How to do it.

As another example, in the mobile terminal, a search for an external device capable of Bluetooth communication is performed, and in a state where the list 200 for external devices capable of Bluetooth communication is output as shown in FIG. 5A (a) , When a specific item (for example, an item for an external device corresponding to "Device A") is selected, as shown in FIG. 5A, A list 210 containing information on the functions that can be output may be output. The information on the functions may be referred to from identification information or separate data received from the external device.

If the audio sharing function is supported by the external device corresponding to the specific item, the list 210 may include an item 211 related to the execution of the audio sharing function. Accordingly, the controller 180 may request the external device to perform the audio sharing function in response to the item 211 being selected. The operation in the mobile terminal and the external device with respect to the audio sharing function can be applied to the same or similar operations as those shown in Figs. 2, 3A and 3B, and thus a detailed description thereof will be omitted.

On the other hand, as another example, a search for an external device capable of Bluetooth communication is performed in the mobile terminal, and a list 200 for external devices capable of Bluetooth communication is output as shown in (a) 5B, if a specific item (for example, an item for an external device corresponding to "Device B") is selected in the state of FIG. 5B, A list 210 containing information on functions that can be performed may be output. The information on the functions may be referred to from identification information or separate data received from the external device.

In this case, if the audio sharing function is not supported by the external device corresponding to the specific item, the list 220 may not include an item related to the execution of the audio sharing function. Accordingly, the user can recognize whether the external device supports the audio sharing function through individual selection for each item.

On the other hand, with the audio sharing function being performed with the external device, the mobile terminal can terminate the audio sharing function based on the user's selection. The user's choice can be made in a variety of ways.

For example, as shown in FIG. 6A, a GUI (Graphical User Interface) for managing settings related to Bluetooth communication or an audio sharing function may be terminated based on a selection of a user on the GUI screen 200a . The GUI related to the Bluetooth communication may include an item 201a including information on an external device currently performing an audio sharing function.

6A, the control unit 180 determines whether or not the item 201a is selected as a function that can be performed in association with the external device corresponding to the selected item 201a, as shown in FIG. 6A, And outputting a list 210 including information on the information items.

In this case, the list 210 may include an item 211a related to the execution of the audio sharing function. Accordingly, the control unit 180 can terminate the audio sharing function with the external device in response to the item 211a being selected. In this case, the pairing between the external device and the mobile terminal can be canceled.

As shown in (a) of FIG. 6B, the control unit 180 of the mobile terminal may output notification information or a window for setting a terminal function And an indicator window 230 indicating that the audio sharing function is being executed. This window 230 may be output based on a predetermined touch (e.g., a drag touch) with respect to a predetermined area (e.g., the upper end of the display unit) of the mobile terminal. In this way, the control unit 180 can output the notification information 231 for the audio sharing function in the window 230, receive the user's selection on the window 230, As shown, the audio sharing function can be terminated.

5A, 5B, 6A, and 6B, a description is given of the operation of the audio sharing function described in FIGS. 5A, 5B, 6A, and 6B, The embodiment of the request for termination can be equally applied to an external device.

Hereinafter, a method of setting a sound to be shared with a mobile terminal among output target sounds in an external device will be described in more detail with reference to the accompanying drawings. 7A, 7B, and 7C are conceptual diagrams illustrating a method for setting a sound to be output.

In the external device, only sound associated with an application or function corresponding to a predetermined type in the external device can be shared with the mobile terminal. In the external device, only the audio data corresponding to the application or the function corresponding to the predetermined type among the audio data for the output target sound can be selectively transmitted to the mobile terminal. For example, an external device may share a notification tone for a text message when a character is received, but not share a ringing tone when a call is received.

On the other hand, information on whether or not to share a sound may be stored in advance in a memory of an external device or a mobile terminal. Therefore, the external device refers to the information stored in the memory of the external device to share the audio data, or receives information existing in the memory of the mobile terminal, and can transmit the audio data to be shared to the mobile terminal only have.

On the other hand, selection of an application or a function corresponding to a predetermined type corresponding to audio data to be shared with an external device may be performed by an external device or a mobile terminal, or both.

7A, if the audio sharing function is requested in the mobile terminal 100, the control unit 180 determines whether the audio sharing function is enabled, as shown in FIG. 7A, A GUI (Graphical User Interface) or such a GUI screen 250 for receiving an application to be shared audio data through the Internet. Accordingly, the user of the mobile terminal can perform selection of the sound to be shared through such screen. The time at which the screen 250 is output may vary.

As another example, as shown in (b) of FIG. 7A, an application or function corresponding to a predetermined type can be selected on the external device side. 7B, when the mobile terminal 100 requests the audio sharing function, the external device 300 notifies the notification information 301 that the execution of the audio sharing function is requested, Can be output. On the other hand, in this case, as shown in FIG. 7B (b), in the external device, a GUI (Graphical User Interface) for receiving an application to be shared audio data through the audio sharing function, (310) to select an output target sound to be shared with the mobile terminal from the user. 7A and 7B, the application or function corresponding to the predetermined type can be selected individually, as shown in FIGS. 7C and 7B, Mode so that the applications or functions shared may be different depending on the mode.

For example, if the first mode (e.g., incognito mode) is selected, as shown in FIG. 7C (b), an application or function related to privacy (e.g., a phone ringtone, ) Are not shared. If a second mode (for example, a normal mode) different from the first mode is selected, all sounds generated in the external device can be shared. The selection for this mode can be made from either the mobile terminal or the external device.

In addition to the above-mentioned methods, the selection of the sound to be shared can be performed through various methods.

Hereinafter, a method for changing the Bluetooth communication method used for the audio sharing function to another communication method according to the communication state between the mobile terminal and the external terminal will be described in detail with reference to the accompanying drawings. 8A, 8B and 8C are conceptual diagrams illustrating a method of outputting information related to a communication state.

The audio sharing function according to the present invention may share the audio data through the Bluetooth communication method, so that the distance between the terminals may be restricted. Therefore, if the distance between the terminals is far enough that the Bluetooth communication is impossible, the audio sharing function may be terminated. Accordingly, when at least one of the mobile terminal and the external device has a data communication sensitivity between the devices, the control unit induces an audio sharing function with the external device through a communication method different from the Bluetooth communication method Guidance information can be output.

In this case, the control unit of at least one of the mobile terminal and the external device can determine whether the communication state between the devices is good based on at least one of the data transmission rate, the reception rate and the transmission rate. For example, when the mobile terminal 100 and the external device 300 can communicate with each other within a reference distance 'a' as shown in (a) of FIG. 8A, When the mobile terminal 100 and the external device 300 move away from the reference distance 'a' to a distance of 'b' as shown in FIG. 8 (b), the controller 180 Information can be output. Such announcement information may be output through at least one of an auditory, visual, and tactile manner.

As an example, the control unit 180 can output guidance information 261 informing that the communication state with the external device is currently poor, as shown in (a) of FIG. 8B. Also, the control unit 180 can determine the reason why the communication state is not good, and output information based on the determination. For example, if it is determined that the communication state is not good due to the distance between the devices, the control unit 180 may output guidance information for inducing the mobile terminal to be located near the external device.

As another example, the controller 180 may generate guide information 262 for inducing an audio sharing function with the external device through a communication method different from the Bluetooth communication method, as shown in FIG. 8B (b) Can be output. If the user selects to use another communication method based on the guidance information 262, the control unit 180 displays screen information for selecting a communication method (for example, pop-up Window, 263). The communication method may be at least one of various communication methods such as Wi-Fi Direct, Wi-Fi, 4G, 3G, and LTE. Meanwhile, when one of the communication methods is selected through the screen information 263, the controller 180 can newly establish a communication connection with the external device to perform the audio sharing function using the selected communication method. For example, when the Wi-Fi Direct function is selected, the control unit 180 may perform an authentication process for data communication with an external device. In this case, the authentication process can be similarly performed on the external device side. On the other hand, when the communication mode is selected, the controller 180 outputs information on the selected communication mode to the external device, and receives permission to perform the audio sharing function according to the selected communication mode. The permission may be made based on information included in data received from an external device.

On the other hand, if the communication mode is selected, the controller 180 can activate a wireless communication module for performing the selected communication mode, and can transmit information on the communication mode to an external device. Therefore, on the external device side, the communication module can be activated so as to use the communication method based on the information on the communication method.

Meanwhile, although the above description has been made with reference to the mobile terminal, the above embodiments can be similarly applied to an external device, and a detailed description thereof will be omitted.

The control unit 180 can display the graphic data by overlapping with the screen information previously displayed on the display unit 151. [ On the other hand, the control unit 180 may generate a new area while displaying at least a part of the screen information previously displayed on the display unit 151, and display the graphic data in the generated area. For example, when the connector of the earphone 400 is coupled to the earphone port, the controller 180 displays graphic data (e.g., an image having the shape of the earphone connector) indicating that the earphone is connected to the display unit 151 It can be displayed in an area adjacent to the earphone port (not shown). Accordingly, the emotional effect indicating that the earphone connector is coupled to the earphone port can be provided to the user. Thereafter, at least one execution menu may be displayed on the display unit 151 so that the function related to the detection result can be executed, wherein one of the related functions may be an audio sharing function. 9A, when the graphic object 271 for receiving an execution request for the audio sharing function is output to one area 270, the graphic object 271 is selected The control unit 180 may determine that an audio sharing function execution request has been received. In response to such a request, the control unit 180 may output screen information for setting an audio sharing function. For example, as shown in (c) of FIG. 9A, the controller 180 may output the list on the display unit to select an external device that supports the audio sharing function, Can be selected. If any one of the external devices is selected, the controller 180 can output a sound corresponding to the audio data received from the selected external device through the interface.

Meanwhile, when the graphic object 271 is selected in the one area 270, the controller 180 determines whether the Bluetooth communication function is activated. If the Bluetooth communication function is inactivated, can do.

9A and 9B, when the connection between the earphone 400 and the interface is released, sound output corresponding to the audio data received from the external device is output Can be stopped. In this case, the control unit 180 outputs a subtitle (or subtitle information) 271 corresponding to the audio data received from the external device to one area of the display unit, or, as shown in FIG. 9 (c) It is possible to output notification information 272 indicating that the earphone connection is released.

Here, the caption information may be received from the external device, or may be generated by referring to the audio data in the mobile terminal itself.

On the other hand, as shown in (c) of FIG. 9, when the earphone connection is released, the control unit 180 determines whether or not to perform the audio sharing function, such as ending the audio sharing function or using a speaker instead of the earphone It can be received from the user. Therefore, the user can unintentionally prepare for the case where the earphone is disconnected from the mobile terminal. Also in this case, the control unit 180 can also output the caption information 273 corresponding to the audio data, as shown in Fig. 9C.

Meanwhile, when the earphone is reconnected within the reference time after the connection between the earphone and the mobile terminal is released, as shown in (a) of FIG. 9d, A sound corresponding to the audio data can be output again through the earphone. If the connection between the earphone and the mobile terminal is canceled, the control unit 180 can output the caption. If the connection between the earphone and the interface unit is not established during the reference time, the control unit 180 ends the output of the caption, The sharing function can be terminated.
