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

As shown, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention controls the components of the above-described mobile terminal 100, including a process of setting and releasing the lock screen, which will be described later. Each step of the embodiments can be performed.

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

In general, when a user inputs a preset line or figure pattern, pin number, or password through the displayed lock screen, the lock state of the mobile terminal 100 is released, and the user manipulates the mobile terminal 100 to display an application desired by the user. You can run it.

In this embodiment, the lock state of the mobile terminal 100 is set and released using a negative pattern instead of the general line or figure pattern, pin number, or password as described above.

In the present embodiment, when a user input through a predetermined specific component of the user input unit 130 is received (S210), the controller 180 of the mobile terminal 100 checks the current state of the mobile terminal 100 (S220). ).

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

In the present embodiment, the lock screen includes an image for inputting a sound pattern. The image for inputting the sound pattern may be, for example, in the form of a piano keyboard which is intuitively easy to recognize the sound, and may adopt any image capable of recalling the sound, such as the score form, the note display, and the like. In the following embodiments will be described the piano keyboard form as an example.

As an image form for inputting a sound pattern, the piano keyboard may be implemented to allow touch input of all of the sounds corresponding to the white and black keys, or may be implemented to allow only the white keys to be touched.

3 illustrates an example of a lock screen including an image for inputting a sound pattern in the form of a piano keyboard.

Referring to the drawings, the upper portion of the lock screen shows a sound pattern input image in the form of a piano keyboard, and the lower portion shows a simple phrase for guiding the user's sound pattern input.

Text such as a phrase for guiding a sound pattern input may be omitted, and a part corresponding to an inputtable sound in the form of a piano keyboard may be displayed to be distinguished from other parts by a specific figure or a different color or highlight.

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

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

Referring to the drawings, for example, the user may sequentially touch the first, third, and fifth white keys from the left to input sound patterns corresponding to the degrees, beauty, and soles respectively corresponding thereto.

In addition, the time interval for sequentially touching each key may 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 sound is continuously input according to the rhythm.

The number of keys input by the user can be sequentially inputted without restriction on the length of the input sound.

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

The input sound pattern is not only limited in length, but may also include the same sound, here, the same key, in the selection of each sound constituting the sound pattern. However, it may be preferable that the sound pattern is composed of a plurality of sounds, that is, at least two or more sounds in order to prevent unlocking according to any input.

Referring to the drawings, as a sound pattern corresponding to degrees, beauty, soles, and degrees, the keys of the first and fourth notes are the same. According to this method, music in which the same sound is repeated can be used as a user-defined sound pattern.

FIG. 6 is a diagram for explaining another example of inputting a sound pattern through an image of a piano keyboard shape.

In the mobile terminal 100, a terminal implemented to enable a plurality of different touch inputs at the same time, that is, a terminal capable of multi-touch, may set a sound pattern for simultaneously inputting different sounds.

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

Referring to the drawings, a pattern of notes is input as a chord by simultaneously touching the positions of piano keys corresponding to FIGS.

When a sound pattern is input as a chord, since a plurality of sounds are input even with a single sound pattern input, even when a sound pattern composed of one input is used, unlocking according to any input can be sufficiently prevented.

When the user inputs a specific sound pattern, the controller 180 receives the input sound pattern (S240), checks whether the sound pattern matches the preset sound pattern (S250), and if the sound pattern matches, locks the mobile terminal 100. The state is released (S260).

The user may preset a sound pattern for releasing the locked state of the mobile terminal 100 through an environment setting menu for controlling the mobile terminal 100 such as terminal configuration of the mobile terminal 100.

On the other hand, the length or time of each sound, that is, the duration of each key or individual touch can be determined to determine the identity of the sound pattern only by the order of the sound without particular limitation. That is, the sameness of the sound patterns may be determined by considering only the sequential order of the resulting sound patterns irrespective of the length or length of each individual sound.

However, the present invention is not limited thereto, and in accordance with not only the sameness in the order of the notes, but also the length and the beat of the note, the correspondence within a predetermined error range for a predetermined time length for each note constituting the note pattern. It may be implemented to determine whether or not.

For example, if 1 second is set to 1 second for the first degree, 2 seconds to the longest sound for the first degree, and 1 second for the shortness for the sole, the sound patterns of the actual degrees, beauty and sole are sequentially For example, when the input signal is input within an error range of, for example, about 20% at 1 second, 2 seconds, and 1 second, the same sound pattern may be determined.

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

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

In addition, in the present invention, the screen 710 for performing a quick launch function may be displayed instead of the home screen after 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 limited to the execution of the quick execution function, and may be partially released only for the execution of the application registered as the quick execution function.

That is, when the locked state of the mobile terminal 100 is released to perform the quick execution function, the application may be implemented such that only the application registered with the quick execution function is selected and executed in the quick execution screen by displaying the quick execution screen.

In addition, the unlocking for performing the quick launch function may be set to be released using a different sound pattern than the unlocking of the entire application for the home screen display.

In addition, the application displayed on the quick launch screen may be limited to an application registered by the quick launch function, but may be implemented to display a predetermined number of applications in the order of applications frequently used by the user without user registration or together with the user registration application.

The quick launch screen may be implemented such that the application is executed by selecting the icon by displaying a shortcut icon of an application registered as a quick launch function in the lock screen without unlocking the lock screen.

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

As shown, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention controls each component of the above-described mobile terminal 100 to set and release the lock screen and perform a quick execution function. Inclusion, each step of the embodiments described below can be performed.

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

When it is determined that the state of 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 are diagrams for describing a process of releasing a control state of a mobile terminal 100 and performing a quick execution function through a lock screen.

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

That is, as shown in FIG. 9, when the user touches the white keys displayed on the lock screen for a long time, for example, recently used applications may correspond to the positions of the white keys in order from the left. .

In this case, the types of keys touched by the user and the applications displayed corresponding thereto may be the order of applications recently used for each of the white keys, as described above. Alternatively, the user may preset the application for each of the white keys. In addition, the types and methods of the keys to which the applications are set in correspondence are various. For example, the applications may correspond to the black keys, respectively, or the user may preset the types of the corresponding keys or the application corresponding methods themselves.

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

For example, the location where the application is displayed may be on a black keyboard as shown in FIG. 9, and various locations such as the top or bottom of the lock screen may be set.

Meanwhile, the user may check an application corresponding to the touched keyboard and touch another key again to display another application. In this case, another application may be displayed instead of the previously displayed application.

Subsequently, while the application corresponding to the touched keyboard is displayed, the user may input a preset sound pattern for unlocking the locked state.

Accordingly, the controller 180 receives the input sound pattern (S860), and checks whether the predetermined sound pattern matches the preset sound pattern (S870).

If the input sound pattern matches the preset sound pattern, the controller 180 controls each component of the mobile terminal 100 to execute the selected application (S880).

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

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
