FIG. 2 is a flowchart showing the operation of the mobile terminal of FIG. 1;

As shown in the figure, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention controls each component of the mobile terminal 100 to set and release a lock screen, Each of the steps of the embodiments can be performed.

The lock screen is displayed on the user input 130 to control a component including the power supply 190 and / or the output 150 of the mobile terminal 100 when the mobile terminal 100 is in the locked state. Is displayed on the display module 151 under the control of the controller 180 when a specific signal is input through at least one component among predetermined components such as a specific key pad, a dome switch, a jog wheel, and a jog switch .

When the user inputs a predetermined line, figure pattern, pin number, password, or the like through the displayed lock screen, the locked state of the mobile terminal 100 is released and the user operates the mobile terminal 100 to select an application Can be executed.

In this embodiment, the lock state of the mobile terminal 100 is set and released using a negative pattern, not a general line or figure pattern, pin number, or password, as described above.

The control unit 180 of the mobile terminal 100 checks the current state of the mobile terminal 100 when the user input through the predetermined specific element of the user input unit 130 is received at step S210 ).

If it is determined that the current state of the mobile terminal 100 is locked (Y in S220), the controller 180 controls the display module 151 of the output unit 150 to display a lock screen (S230) .

In this embodiment, the lock screen includes an image for inputting a negative pattern. The image for inputting the sound pattern may be, for example, a piano keyboard type that is intuitively easy to recognize a sound, and may adopt any image capable of reminding sounds such as score, note, and the like. In the following embodiments, the piano keyboard type will be described as an example.

As an image type for inputting a sound pattern, the piano key shape can be implemented so that both the white key and the sound corresponding to the black key can be touch input, or a simple white key can be input.

3 shows an example of a lock screen including an image for a negative pattern input in the form of a piano keyboard.

Referring to the drawing, a piano keyboard-shaped voice pattern input image is shown at the upper end of the lock screen, and a simple phrase for guiding the user's voice pattern input is displayed at the lower end.

Text such as a phrase for guiding the input of a tone pattern may be omitted and a portion corresponding to an inputable tone of the piano keyboard type may be displayed so as to be distinguished from other portions by a specific figure or a different color or highlight.

On the other hand, when the user touches the keyboard part of the piano shape and the user inputs a sound, the controller 180 outputs the sound corresponding to the input part through the sound output module 152 of the output unit 150 can do. In addition, the controller 180 may provide feedback such as vibrations according to a user's touch through the haptic module 154 in response to the touch input of the user.

4 is a diagram for explaining an example of inputting a tone pattern using an image of a piano keyboard shape.

Referring to the drawing, a user may sequentially touch the first, third, and fifth white keys from the left side, for example, and input a tone pattern corresponding to each of the corresponding degrees of figure, scale, and brush.

In addition, a time interval for sequentially touching each key can be set to, for example, a time of about 1 second or 2 seconds, so that the next key is touched within a set time so that the note is continuously input according to the rhythm.

It is possible to sequentially input a plurality of keys set by the user without limitation to the length of the input sound.

5 is a view for explaining another example of inputting a tone pattern through an image of a piano keyboard shape.

Not only the length of the input sound pattern is not limited, but also the same key in the selection of each sound constituting the sound pattern, in this case, the same key can be selected redundantly. However, it is preferable that the sound pattern is composed of a plurality of sounds, that is, at least two sounds, in order to prevent unlocking according to any input.

Referring to the drawings, the key patterns corresponding to the first and fourth keys are the same as the key patterns corresponding to the degrees, the borders, the brushes, and the figures. According to this method, it is possible to utilize music that repeats the same note as a user-set tone pattern.

6 is a view for explaining another example of inputting a tone pattern through an image of a piano keyboard shape.

In a terminal implemented to be able to input a plurality of different touches at the same time in the mobile terminal 100, that is, a terminal capable of multi-touching, it is possible to set a tone pattern for simultaneously inputting different sounds.

Accordingly, a tone pattern can be set so that different notes are input simultaneously to form a chord.

Referring to the drawing, a pitch pattern is input as a chord by simultaneously touching the positions of the piano keys corresponding to the figure, the scale, and the brush.

If a tone pattern is input as a chord, a plurality of notes are input even when only one tone pattern is input. Therefore, even if a tone pattern composed of a single input is used, unlocking according to an arbitrary input can be sufficiently prevented.

When the user inputs a specific tone pattern, the control unit 180 receives the input tone pattern (S240) and checks whether the tone pattern matches the preset tone pattern (S250). If the tone pattern matches, The state is canceled (S260).

The user can preset a tone pattern for releasing the locked state of the mobile terminal 100 through a configuration menu for controlling the mobile terminal 100, for example, a terminal environment setting of the mobile terminal 100. [

On the other hand, it is possible to judge the identity of the tone pattern by the order of the notes without any specific limitation, for the length or time of each note, i.e., the time duration of each key or individual touch. That is, it is possible to determine the identity of the sound pattern by considering only the sequential order of the sound patterns to be input, irrespective of the end or beat of each individual sound.

However, the present invention is not limited to this, and consideration is given to not only the identity in the negative order but also the negative long end or the beat, and for each note constituting the sound pattern, correspondence within a predetermined error range As shown in FIG.

For example, if the first degree is set to 1 second for mono, 2 second for long, and 1 second for sol, for the first, second, and sole notes, the sound pattern of actual, It may be determined that the same sound pattern is input when the sound is input within an error range of about 20%, for example, 1 second, 2 seconds, and 1 second, respectively.

FIG. 7 is a diagram for explaining a quick execution function according to the lock screen release method of FIG. 2. FIG.

In the present invention, the home screen may be displayed after the lock state is released as described above.

Also, in the present invention, a screen 710 for executing a quick launch function (not a home screen) may be displayed after the unlocking as described above.

In this case, the unlocking is not limited to the execution of the entire application executed in the mobile terminal 100 but is limited to the execution of the quick execution function, and may be partially canceled only for execution of only the application registered with the quick execution function.

That is, when the locked state of the mobile terminal 100 is released for executing the quick execution function, only the application registered with the quick execution function can be selected and executed in the quick execution screen by displaying the quick execution screen.

In addition, the unlock for performing the quick execution function may be set to be released using a different sound pattern from the unlock for the entire application for the home screen display.

The application displayed on the quick execution screen may be limited to the application registered with the quick execution function, but it may be implemented to display a certain number of applications without the user registration or with the user registration application in order of the application frequently used by the user.

On the other hand, the quick execution screen may be implemented such that the corresponding application is executed by selecting the icon by displaying a shortcut icon of the application registered as the quick execution function in the lock screen without releasing the lock screen.

FIG. 8 is a flowchart illustrating an operation of the mobile terminal of FIG. 1 according to another embodiment of the present invention.

As shown in the figure, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention controls each component of the mobile terminal 100 to set and release a lock screen and perform a quick execution function And perform the steps of the embodiments described below.

When a user signal for controlling the components including the power supply unit 190 and / or the output unit 150 of the mobile terminal 100 is received (S810) when the mobile terminal 100 is in the locked state, 180) confirms the current state of the mobile terminal 100 (S820).

If it is confirmed that the mobile terminal 100 is in the locked state (S820: Y), the controller 180 controls the display module 151 to display the lock screen (S830).

9 and 10 illustrate a process of releasing the control state of the mobile terminal 100 through the lock screen and performing a quick execution function.

The control unit 180 determines whether a specific sound corresponding to a predetermined specific position on the lock screen displayed on the display module 151 by the user is selected (S840).

That is, as shown in FIG. 9, when a user touches a white key displayed on the lock screen for a long time, recently used applications corresponding to each position of the white key in order from the left can be corresponded in order .

In this case, the types of keys the user touches and the applications displayed corresponding thereto may be the order of applications that have been used recently for each of the white keys as described above. In addition to this, Or the user may set the application for each of the white keys in advance. In addition, the types and methods of the keys to which the applications are set correspond to each other. For example, the applications may be associated with the black keys, and the user may set the types of the corresponding keys and the application corresponding method itself.

When a user touches a specific key, an application corresponding to the key is displayed at a predetermined position of the lock screen (S850).

The position at which the application is displayed may be on a black key, for example, as shown in FIG. 9, and various positions such as the top surface or the bottom surface of the lock screen may be set.

On the other hand, the user can confirm the application corresponding to the touched key and again touch another key to display another application. In this case, other applications may be displayed instead of the previously displayed application.

Then, in a state where the application corresponding to the touched key is displayed, the user can input a predetermined tone pattern for releasing the lock state.

Accordingly, the control unit 180 receives the input tone pattern (S860) and confirms whether or not the tone pattern matches the predetermined tone pattern (S870).

The control unit 180 controls each element of the mobile terminal 100 to execute the selected application (S880) if the input sound pattern coincides with the preset sound pattern.

In this case, depending on the setting, the lock screen is released and the application may be executed or the application may be executed in the lock screen state.
