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 the presence of an object in the vicinity of the detection surface, without mechanical contact by using 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.

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, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched 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 touching 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 sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is arranged to scan the motion of the object to be sensed 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.

In addition, the control unit 180 performs control and processing related to voice communication, data communication, video call, or the like, or performs pattern recognition processing to recognize handwriting input or drawing input performed on the touch screen as characters and images, respectively . Further, the controller 180 may control any one or a plurality of the above-described components in order to implement various embodiments described below on the mobile terminal 100 according to the present invention.

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.

1B and 1C, a mobile terminal according to the present invention includes a main body 200, a display unit 251 disposed on a front surface of the main body, a wheel 201 configured to surround the display unit 251, A wheel 201 may be provided.

The body 200 has a circular shape and may be formed of various materials. For example, various materials may include metals, synthetic resins, and the like.

The display unit 251 may be disposed on the front surface of the main body so as to display visual information. Also, the display unit 251 may be formed in a circular shape.

The display unit 251 may further include a touch sensor to detect a touch input of a user applied to the display unit 251.

The wheel 201 may be formed in a hollow shape (or a donut shape or a ring shape) so as to surround the outer periphery of the display portion 251. In this case, the shape of the wheel 201 may be determined according to the shape of the display unit 251. For example, referring to FIG. 1B, the wheel 201 may be hollow.

The wheel 201 can be formed to move based on the operation of the user. For example, the wheel 201 can rotate based on an external force applied from a user.

Further, the wheel 201 may further include a touch sensor to sense a touch applied to the surface of the wheel. Such a touch sensor can form a layer structure with the surface of the wheel 201.

Accordingly, the user can generate the control command by rotating the wheel 201 or by touching the surface of the wheel 201. [

Hereinafter, a control method of a mobile terminal having at least one of the above-described components will be described with reference to the drawings. In the following description of the drawings, the drawings drawn on the left side are referred to in the order of clockwise or top-down.

2 is a conceptual diagram illustrating a state where a mobile terminal and an external speaker are connected to each other according to the present invention.

The mobile terminal according to the present invention can perform communication with an external speaker through short-range communication. In the short-distance communication, the scheme described above with reference to FIG. 1A may be used.

Referring to FIG. 2, when performing communication with the external speaker, the mobile terminal can audibly output specific contents through an external speaker.

Here, the specific content may be sound content. The specific contents may be stored in the memory 170 of the mobile terminal or may be received in real time on the mobile terminal through communication from an external server (or an external device).

Hereinafter, a method of providing specific contents to be output through an external speaker will be described. 3 is a flowchart illustrating a control method of providing contents in a mobile terminal according to the present invention. 4A and 4B are conceptual diagrams illustrating a method of authenticating a user through a user operation applied to a wheel in a mobile terminal related to the present invention.

A mobile terminal according to the present invention can detect an input pattern corresponding to a touch of a user's finger and a rotational movement of a wheel applied to the wheel (S410).

The control unit 180 may sense at least one of an input corresponding to a touch input by the user's finger applied to the wheel and an input corresponding to the rotational movement of the wheel.

To this end, the mobile terminal may further include a sensing unit for sensing the rotational movement of the wheel and the touch of the user's finger applied to the wheel. For example, the sensing unit may include a gyro sensor and a touch sensor.

Here, the rotation of the wheel may have either a clockwise or counterclockwise direction. In addition, the user can rotate the wheel 201 by applying an external force to the wheel 201. [

The control unit 180 may sense an input corresponding to the rotational motion of the wheel 201. [ The input corresponding to the rotational motion may be different according to the rotational property (e.g., rotational speed, rotational length, etc.) of the wheel 201. [ For example, a rotational movement having a first rotational speed may correspond to a first input, and a rotational movement having a second rotational speed may correspond to a second input.

In addition, the wheel 201 may be divided into a plurality of areas in order to sense a touch applied to the surface of the wheel 201. The plurality of regions may be partitioned based on predetermined reference points. In this case, the controller 180 can detect the touch position based on the position of the area where the touch is detected among the plurality of areas.

In addition, the wheel 201 may further include a skin adhesion sensor for sensing an electrical change of the skin surface. In this case, when the wheel 201 is touched, the controller 180 can detect the skin conductance due to the skin of the finger that touches the wheel 201.

The skin electrical conductivity is a value that numerically indicates the electrical change of the skin. Such skin electrical conductivity may be changed according to the emotional state of the user. For example, if the user is in a stressed state or in an excited state, a skin electrical conductivity that is more exciting than normal skin conduction can be detected.

When the rotation of the wheel 201 and a touch on the surface of the wheel 201 are detected, the controller 180 controls the input corresponding to the rotational motion of the wheel 201 and the input corresponding to the rotational movement of the wheel 201, It is possible to detect an input pattern of an input corresponding to an applied touch.

The input pattern may be a combination of an input corresponding to the rotational motion of the wheel 201 and an input corresponding to a touch applied to the surface of the wheel 201. For example, the input pattern may be an input pattern corresponding to a rotation movement rotating at a first speed in a state where a touch is detected in a specific area.

The input pattern may vary depending on the user. That is, each user can have a unique input pattern. Therefore, the control unit 180 can distinguish the user based on the input pattern.

This unique input pattern can be determined by the size of the user's hand, the propensity of the user, and the like.

For example, as shown in the first drawing of Figs. 4A and 4B, since the size of the hands of the adult and the hands of the child are different from each other, the eye includes two specific regions 202a, 202c, and the adult can apply a touch to another specific two areas 202a, 202d.

As another example, although not shown, a person with a sudden personality may rotate the wheel 201 rapidly, and a person with a sudden personality may rotate the wheel 201 more slowly. As another example, though not shown, the preferred touch positions may be different for each user.

For example, as shown in the first drawing in Fig. 4A, the first user may have a first input pattern rotating at a first speed, with the touch being sensed at the first position of the wheel 201. [ As another example, as shown in the first drawing of Fig. 4B, the second user may have a second input pattern rotating at the second speed, with the touch being sensed at the second position of the wheel 201. [

Also, the controller 180 may detect an input pattern based on the input corresponding to the rotational movement, the input corresponding to the touch applied to the surface of the wheel 201, and the input corresponding to the skin electrical conductivity. A concrete explanation of this will be replaced with the preceding explanation.

The mobile terminal according to the present invention can detect specific user information among a plurality of user information based on an input pattern (S420).

When an input pattern is detected, the control unit 180 can detect specific user information among a plurality of user information based on the detected input pattern.

A plurality of pieces of user information may be stored in the memory 170 by the user. Here, the user information may include ID, identification information, password information, log-in information, and the like.

The control unit 180 may determine an input pattern to be mapped to specific user information. That is, the controller 180 can detect an input pattern of a specific user using the mobile terminal in real time and map the detected input pattern to a specific user. Accordingly, when the specific input pattern is received, the control unit 180 can detect the specific user information mapped to the specific input pattern.

The mobile terminal according to the present invention may display a content list including at least one content mapped to specific user information on the display unit (S430).

The control unit 180 may display the content list including at least one content mapped to specific user information on the display unit 251 when specific user information is detected.

For this, the control unit 180 can perform login based on the specific user information. Here, the login is the operation of the mobile terminal to acquire the right to access the specific information only by the user having the specific user information through the ID and the password of the specific user.

When the login is performed, the control unit 180 may detect a content list including at least one content mapped to specific user information.

The at least one content may be content stored on an external server (e.g., a web server) or content stored on the memory 170 of the mobile terminal.

The external server may be a content server for storing contents. Such an external server may have storage space for storing a plurality of contents (for example, a cloud, a web hard, etc.).

When the login is performed, the control unit 180 may obtain the right to access at least one content stored in the external server. In this case, the control unit 180 may display at least one content on the display unit 251. For example, as shown in FIG. 4A, when the specific user information is detected based on the first input pattern, the controller 180 can perform login based on specific user information. Thereafter, the controller 180 may display a content list including at least one sound content mapped to the specific user A information on the display unit 151.

The at least one content may be content preset by a specific user. For example, a user can select at least one content among a plurality of contents stored in an external server. In this case, the controller 180 may map the selected at least one content to specific user information. Accordingly, the control unit 180 may display at least one content mapped to the specific user information on the display unit 151, when the login is performed, based on the specific user information.

Or the at least one content may be determined by a use pattern of a specific user. In this case, the control unit 180 may detect a usage pattern of a specific user, and may map at least one content to specific user information based on the detected usage pattern. Here, the usage pattern may include information such as frequently played back content, recently played back content, a genre of the content, a maker of the content, and the like. Therefore, the user can receive appropriate contents suitable for his / her taste without any separate control command.

Also, the controller 180 may provide different contents for each user mapped to the input pattern. For example, as shown in FIG. 4B, when a specific user and another user B information are mapped to the detected input pattern, at least one content mapped to other user information is displayed on the display unit 180. [ Can be displayed on the display unit 151.

On the other hand, if the specific user information is not detected based on the detected input pattern, the controller 180 may not perform login. In this case, the control unit 180 may not display the content list including at least one content mapped to the specific user information on the display unit 151.

In this case, the control unit 180 can display the default content set on the display unit 151. The default content may be content that is not mapped to specific user information, that is, content that is provided by an external server, or that is set as a default content at the time of factory initialization of the mobile terminal.

In addition, if the login is not performed, the user can perform login through an external electronic device (e.g., a smart phone or a tablet PC) performing close-range communication with the mobile terminal.

More specifically, when there is an external electronic device that is performing close-range communication with the mobile terminal, the user can operate the external electronic device to perform the login. This login process can be accomplished by inputting an ID and a password in a conventional manner.

When login is performed from the login to the external electronic device, the external electronic device can transmit the login information to the mobile terminal. Accordingly, the mobile terminal can perform login.

The control unit 180 may control an external speaker so that the at least one content is audibly output based on a control command of the user after the content list including the at least one content is displayed. The external speaker may be an electronic device performing short-distance communication with the mobile terminal.

The control unit 180 may communicate with the external speaker through a control command of the user or the wireless communication unit 110 automatically. For example, the control unit 180 may perform communication with a specific external speaker based on a user's control command for communicating with an external speaker. As another example, when the external speaker having the stored identification information is located within a preset range based on the position of the mobile terminal, the controller 180 can automatically communicate with the external speaker.

Accordingly, the present invention can audibly output various contents provided by the mobile terminal through the external speaker.

In addition, in the present invention, in addition to an external speaker, if the speaker itself is provided, at least one content can be output through a speaker provided therein.

In the foregoing, a method of recognizing a user by using a user's input pattern applied to the mobile terminal and providing contents suitable for each user has been described. In this way, the user can conveniently receive customized content without an existing login process.

Hereinafter, a method of controlling the content through the rotational movement of the wheel and the touch applied to the wheel will be described. 5A and 5B are conceptual diagrams illustrating a method of controlling content through a rotational movement of a wheel in a mobile terminal according to the present invention. FIG. 6 is a conceptual diagram illustrating a method of controlling contents through a touch operation on a wheel in a mobile terminal according to the present invention.

The control unit 180 can control the content list including at least one content displayed on the display unit 151 based on the rotational movement of the wheel and the touch applied to the wheel.

More specifically, the control unit 180 may move between two content lists based on rotational movements applied to the wheel and / or touches on the wheel, or may scroll through at least one content included in the content list , And can select specific contents.

For example, as shown in FIG. 5A, the control unit 180 may display a currently displayed content list (e.g., a play list) in a different content list (for example, You can go to the list you listen to frequently). That is, according to the present invention, an operation of moving between a content list and a content list may be performed in accordance with a rotation movement of the wheel 201. [

In addition, the control unit 180 can control the moving direction between the content lists according to the rotational direction of the rotational motion applied to the wheel 201. [ For example, as shown in FIG. 5A, when the first content list is displayed and the wheel 201 is rotated in the first direction, the controller 180 determines that the second content list . ≪ / RTI > 5B, when the second content list is displayed and the wheel 201 is rotated in the second direction opposite to the first direction, the control unit 180 determines that the second content From the list to the first content list.

In addition, the controller 180 may scroll at least one content included in the content list based on the dragging of the wheel 201. [

For example, as shown in the first and second figures of FIG. 5A, the controller 180 may perform scrolling between at least one content based on the dragging of the wheel 201.

Also, although not shown, the controller 180 may scroll the wheel 201 in a direction corresponding to a direction in which the dragging is applied. Accordingly, the user can move through the content list through the operation of rotating the wheel, and after the user moves to the desired content list, the user can retrieve the desired content through the touch.

Meanwhile, the controller 180 can visually distinguish the currently selectable content from at least one content included in the content list with the remaining content. For example, as shown in the first drawing of FIG. 6, the controller 180 may display one content, which is selectable among the three contents, differently from other contents.

The controller 180 may move the selectable content in response to the dragging of the wheel. For example, as shown in the second diagram of FIG. 6, the controller 180 may move the selectable content from B.xxx to D.xxx in response to a drag touch on the wheel.

As shown in the third drawing of FIG. 6, the controller 180 can select specific contents in response to the short touch being applied to the wheel while specific contents are set as selectable contents. In this case, although not shown, the control unit 180 can reproduce the specific content through the external speaker.

In the above, a method of controlling contents through various operations applied to the wheel has been described. Accordingly, the user can easily control the content displayed on the display unit without covering the display unit. The present invention is not limited to the content control method, and various functions such as volume control, content reproduction control, and frequency control can be controlled through various operations applied to the wheel. Such a control method is similar to the above-described method, so that description thereof will be omitted.

Hereinafter, a method of executing different functions associated with each of a plurality of areas included in a wheel will be described. 7 is a conceptual diagram showing a method of executing different functions associated with each of a plurality of areas included in a wheel.

The control unit 180 can associate different functions with respect to each of the plurality of regions included in the wheel 201. [

The different functions are functions executable in the mobile terminal. For example, it can be a favorite function, a recent play list function, a playback control function, a power on / off function, a display on / off function, and a volume control function. The favorite function may be a function of reproducing the content that is reproduced most frequently. The recent play list function may be a display function of a recently played list starting from a point of time when a control command is received. The playback control function can be playback stop, stop playback, start playback, rewind, fast forward, and the like.

These different functions can be linked to a specific area by the user, or can be shipped out in advance in factory of the mobile terminal.

For example, referring to FIG. 7, the control unit 180 sequentially displays a plurality of regions 202a, 202b, 202c, 202d, and 202e included in the wheel 201 in the first region 202a, When defining the area 202e, it is possible to associate the favorite function with the fifth area 202e.

As another example, although not shown, the controller 180 may associate a recent playlist function with the first area 202a and a play stop function with the second area 202b.

The control unit 180 displays an execution screen of a function associated with the specific area on the display unit 151 in response to the touch being applied to a specific one of the plurality of areas 202a, 202b, 202c, 202d, and 202e can do. For example, as shown in the first drawing of FIG. 7, in response to touching the fifth region 202e, the control unit 180 displays an execution screen of the favorite function on the display unit 251 Can be displayed.

In response to a touch being applied to the specific area, in response to the touch being applied to the specific area, the control unit (180) It is possible to reproduce the contents included in the execution screen of the program.

In the foregoing, a method of executing a function associated with a specific area has been described. Through this, the user can perform various functions through a simple operation of touching the wheel.

Hereinafter, a method for selecting a specific content among a plurality of contents will be described in the mobile terminal related to the invention, based on the emotion state of the user. 8A and 8B are conceptual diagrams illustrating a method for selecting a specific content among a plurality of contents based on a user's emotional state in a mobile terminal according to the present invention.

The control unit 180 of the mobile terminal according to the present invention can determine the emotional state of the user through the sensing unit through various sensed sensing information.

More specifically, the control unit 180 controls the skin electrical conductivity of the user's finger applied to the wheel 201, the rotational speed of the wheel 201, and the face image of the user input through the camera 221 provided in the mobile terminal The emotional state of the user can be determined based on at least one of the emotional state of the user. A user's emotional state can have states such as joy, happiness, depression, sadness, and stress.

For example, the control unit 180 may determine a user's emotional state of stress when the skin electrical conductivity of the user's finger has a specific pattern and the rotational speed of the wheel is equal to or greater than a predetermined speed. As another example, when the controller 180 determines that the face image of the user looking at the front of the display unit 151 is a smiling face, the controller 180 can determine the user's emotional state of joy.

The control unit 180 can select specific content from the content list including at least one content based on the determined emotion state of the user. More specifically, the controller 180 may select specific content that is mapped to the determined emotional state of the user. The control unit 180 can reproduce the selected specific content through the external speaker.

For example, as shown in the first drawing in FIG. 8A, the controller 180 can sense the skin electrical conductivity of the user's finger applied to the wheel 201. Thereafter, the controller 180 may determine the emotional state of the user based on the skin electrical conductivity.

8A, the control unit 180 can reproduce the specific content "IF you" based on the skin electrical conductivity of the user's finger applied to the wheel 201. [

The control unit 180 may further include a camera 221 having a front direction of the display unit 151 in the photographing direction. In this case, as shown in the first drawing of FIG. 8B, the controller 180 can receive a face image of a user looking at the display unit 151 through the camera 221.

The control unit 180 can determine the emotion state of the user based on the inputted face image of the user. Thereafter, the controller 180 can reproduce specific contents based on the determined emotion state of the user. For example, as shown in the second diagram of FIG. 8B, the controller 180 may select specific contents called " IF you "based on the determined emotional state of the user, have.

Meanwhile, although not shown, the controller 180 may determine the emotional state of the user through a wearable device associated with the mobile terminal. In this case, the controller 180 can receive the user's biometric information (e.g., heart rate information, fingerprint information, etc.) from the wearable device and determine the emotional state of the user.

Accordingly, the user can be provided with contents suitable for his / her emotional state without applying a separate control command to the mobile terminal.

Hereinafter, a method of controlling the reproduction of the content being reproduced by using the touch operation applied to the wheel will be described. Figs. 9A and 9B are conceptual diagrams showing a method of controlling reproduction of content being reproduced by using a touch operation applied to a wheel. Fig.

The control unit 180 can control reproduction of specific content being reproduced by the external speaker through the touch operation of the user applied to the wheel 201 when the specific content is being reproduced through the external speaker.

More specifically, in response to a user's touch operation being performed during playback of a specific content, the controller 180 controls the playback of the specific content to be paused, stopped, moved to the previous or next song, rewound and fast-forwarded At least one can be performed.

The user's touch operation may be a drag touch, a multi-touch, a multi-drag touch, a short touch, a long touch, a double touch, or the like, which is applied to the wheel 201.

For example, as shown in the first drawing of FIG. 9A, the controller 180 may sense a dragging touch in the first direction applied to the wheel 201 during reproduction of a specific content called "Lemon Pie" . In this case, as shown in the second diagram of FIG. 9A, the controller 180 may move to the content 'I miss you' in response to the drag touch in the first direction.

Likewise, as shown in the third drawing of FIG. 9A, in response to a dragging touch in the second direction having a direction opposite to the first direction, the control unit 180 reads "Lemon Quot; Pie ".

As another example, as shown in the first drawing of FIG. 9B, the controller 180 can detect a multi-drag touch applied to the wheel 201 during reproduction of a specific content called "Lemon Pie ". The multi-drag touch may be a touch that is dragged simultaneously on at least two touch points.

In this case, as shown in the second drawing of FIG. 9B, the controller 180 may perform rewinding of the "Lemon Pie" in response to the multi-drag touch in the first direction.

Likewise, as shown in the third drawing of Fig. 9B, the controller 180 can perform fast forwarding of "Lemon Pie" in response to the multi-drag touch in the second direction opposite to the first direction have.

Accordingly, the user can easily control playback of the specific content being played back from the external speaker through the mobile terminal.

Hereinafter, a method of reproducing specific contents using location information of an external speaker communicating with a mobile terminal will be described. 10A and 10B are conceptual diagrams illustrating a method of reproducing specific contents using position information of an external speaker communicating with a mobile terminal.

The mobile terminal according to the present invention may further include a wireless communication unit 110. [ At this time, the controller 180 may perform communication with an external speaker. For example, the control unit 180 may perform communication with an external speaker using a Bluetooth communication method.

Alternatively, the control unit 180 may communicate with the mobile terminal by wire.

The external speaker communicating with the mobile terminal may be an electronic device located within a predetermined range based on the position of the mobile terminal. That is, the controller 180 may communicate with an external speaker located within a predetermined range based on the position of the mobile terminal.

Also, the control unit 180 may perform a control command of the user or automatically communicate with the external speaker. For example, when an external speaker having identification information previously stored on the memory 170 is detected among the external speakers located within a preset range based on the position of the mobile terminal, You can automatically communicate with your speakers.

If a plurality of external speakers located within a preset range and having identification information previously stored on the memory 170 are detected based on the position of the mobile terminal, Lt; RTI ID = 0.0 > 1, < / RTI >

More specifically, when a plurality of external speakers is detected, the control unit 180 may display an identification information list including identification information of a plurality of external speakers on the display unit 151. FIG. In this case, the user can select one or more external speakers to perform communication among a plurality of external speakers included in the identification information list. Thereafter, the controller 180 may perform communication with the selected one or more external speakers.

Alternatively, when a plurality of external speakers, which are located within a predetermined range on the basis of the position of the mobile terminal and have identification information previously stored on the memory 170, are detected, And can communicate with an external speaker.

More specifically, the control unit 180 can detect a relative distance between a plurality of speakers and a mobile terminal based on a beacon signal of each of a plurality of speakers. Thereafter, the controller 180 can perform communication with the external speaker having the shortest relative distance.

If there is an external speaker having the same relative distance, the controller 180 may select the user or perform communication with one of the external speakers based on a predetermined priority. Here, the predetermined priority may be set by frequently connected communication connection history information or by the user.

On the other hand, the controller 180 may change an external speaker for performing communication based on the location of the mobile terminal.

More specifically, when the position of the mobile terminal changes from the first position to the second position, the controller 180 can cancel the communication with the external speaker performing the communication.

Then, the control unit 180 can perform communication with a new external speaker located within a predetermined range based on the second position. The controller 180 may transmit the content being played back to the new external speaker so that the current content is being reproduced on the new external speaker when there is content being played back on the external speaker performing communication.

Accordingly, the controller 180 can continuously reproduce the content being reproduced through another external speaker even when the position of the mobile terminal is changed and communication with the external speaker is interrupted.

The controller 180 can reproduce specific contents included in the mobile terminal by using an external speaker for performing communication.

At this time, the controller 180 may detect position information of an external speaker performing communication.

More specifically, on the memory 170, information that maps specific position information for each identification information of the external speaker can be stored. At this time, when the controller 180 performs communication with a specific external speaker, the controller 180 may detect position information mapped to a specific external speaker.

In addition, the controller 180 can reproduce specific contents based on at least one of position information and time information of an external speaker performing communication.

More specifically, the controller 180 may map specific contents according to location information of the external speaker based on the history information of reproducing the contents. For example, when the user has the history information in which the user repeatedly reproduces the specific content at the location of the "living room ", the controller 180 can map the specific content to the location" living room ". Alternatively, the user can directly map specific content to specific content.

Alternatively, the controller 180 may map specific content to a specific location based on the location and time information. For example, when there is the history information in which the morning call is repeatedly reproduced at 7:00 am and the bedroom position is 7:00 am, the current time is 7:00 am. If it is detected that the bed room is located, , A morning call can be played.

In addition, the controller 180 may map specific content to specific location information based on information that another mobile terminal communicating with the mobile terminal maps specific content at a specific location. For example, the control unit 180 may receive information on a specific position and specific content mapped from another mobile terminal in which identification information is stored on the memory 170, and store the information on the memory 170. [

Thereafter, the controller 180 may automatically reproduce specific content at a specific location.

For example, as shown in FIG. 10A, when the position of a specific speaker is detected as "living room ", the control unit 180 can reproduce specific contents mapped to the" living room ". As another example, as shown in FIG. 10B, when the position of a specific speaker is detected as "bedroom ", the controller 180 can reproduce the specific content mapped to the" bedroom ".

In the above, a method of reproducing specific contents according to at least one of the position and the time of the external speaker communicating with the mobile terminal has been described. Through this, the user can be provided with the most suitable content based on at least one of the current position and the time.

Hereinafter, a method of sharing content among a plurality of mobile terminals providing content will be described. 11A and 11B are conceptual diagrams illustrating a method of sharing content among a plurality of mobile terminals providing content.

The control unit 180 can share content with an external mobile terminal through communication. Here, the sharing of content may be performed by an external mobile terminal, or by reproducing or storing the stored content on a mobile terminal through communication, or by storing the content being reproduced in an external mobile terminal in its own memory, ≪ / RTI >

More specifically, the control unit 180 can store the identification information of each of the plurality of mobile terminals in the memory 170.

As another example, although not shown, the control unit 180 can control the first and second devices 200b and 200c to simultaneously reproduce the same content.

Accordingly, the user can conveniently control a plurality of mobile terminals through one device.

Hereinafter, a method of synthesizing contents being reproduced by a plurality of mobile terminals connected to one speaker and outputting the synthesized contents as one content will be described. 13 is a conceptual diagram illustrating a method of synthesizing contents being reproduced in a plurality of mobile terminals connected to one speaker and outputting the synthesized contents as one content.

When a plurality of mobile terminals according to the present invention perform communication with one speaker, the contents being reproduced by each of the plurality of mobile terminals can be transmitted to the external server.

Hereinafter, for convenience, the plurality of mobile terminals will be described as the first device 200a and the second device 200b. However, the present invention can be equally applied to two or more devices.

The user can control the reproduction speed, the reproduction position, and the like of the contents reproduced in each of the first and second devices 200a and 200b using the wheels of the first device 200a and the second device 200b. That is, the user can control the content reproduced by each device through each device.

The first device 200a and the second device 200b may transmit the content controlled by the user to an external server.

In this case, the external server can generate one content by synthesizing the content being reproduced by each of the plurality of mobile terminals. In addition, the external server may transmit the synthesized content to the first device 200a and the second device 200b such that the synthesized content is reproduced from the one speaker.

 The first device 200a and the second device 200b can output the synthesized content from one speaker.

For example, as shown in FIG. 13, the first device 200a and the second device 200b can communicate with one speaker 1200. FIG. At this time, the first device 200a and the second device 200b can transmit the content being played back to the external server 1210, respectively.

Thereafter, the first device 200a and the second device 200b can receive the synthesized content obtained by synthesizing the content being played back by the first device 200a and the second device 200b from the external server 1210 have. The first device 200a and the second device 200b can control one speaker 1200 to output the synthesized contents through one speaker 1200 through communication.

Therefore, the user can generate and output the synthesized contents in real time.

According to the present invention, the user can be recognized through the touch applied to the wheel and the rotational movement of the wheel. Thus, the present invention can provide contents suitable for each user without performing a login procedure.

In addition, the present invention can control the content displayed on the display unit through various operations using the wheel. Through this, the user can conveniently control the content through a simple operation using the wheel.
