The tab object applying the tab may be the main body of the mobile terminal 100, the display unit 151, or an object that can apply an external force to the object. For example, a finger, a stylus pen, or a pen may be used. (pen), pointer, fist, etc. The tab object is not limited to an object capable of applying a touch input to the mobile terminal 100 according to the present invention, and may apply an external force to the main body, the display unit 151 or the object of the mobile terminal 100. It is irrelevant if it is a thing.

The object to which the tap gesture is applied may include at least one of a main body of the mobile terminal 100 and an object on which the mobile terminal 100 is placed.

Meanwhile, in the present invention, the tap or the tap gesture may be detected by at least one of an acceleration sensor and a touch sensor included in the tap detector. Here, the acceleration sensor is a sensor capable of measuring dynamic forces such as acceleration, vibration and shock of the main body of the mobile terminal 100.

That is, the acceleration sensor may detect the movement (or vibration) of the main body of the mobile terminal 100 generated by the tap gesture and detect whether a tap is applied to the object. Accordingly, the acceleration sensor is located close to the main body of the mobile terminal 100 so as to detect a tap on the main body or the touch screen of the mobile terminal 100 or to detect whether movement or vibration has occurred in the main body of the mobile terminal 100. It can detect that the object is being tapped.

As described above, the acceleration sensor may detect the movement or vibration of the main body of the mobile terminal 100, as well as the case where the tap is applied to the main body of the mobile terminal 100 or the display unit 151. The tap may be sensed even when applied to the off point.

In the mobile terminal 100 according to the present invention, in order to detect a tap on the main body or the display unit 151 of the mobile terminal 100, only one of the acceleration sensor and the touch sensor is used, or the acceleration sensor and the touch sensor are sequentially used. Alternatively, the acceleration sensor and the touch sensor may be used at the same time. Meanwhile, in order to detect a tap, a mode using only an acceleration sensor may be referred to as a first mode and a mode using a touch sensor as a second mode, and utilize both an acceleration sensor and a touch sensor (simultaneously or sequentially). Mode) may be referred to as a third mode or a hybrid mode.

On the other hand, when detecting a tap through the touch sensor, it may be possible to more accurately determine the position where the tap is detected.

Meanwhile, in the mobile terminal 100 according to the present invention, in order to detect the tap through an acceleration sensor or a touch sensor, a minimum current or power is consumed even when the display unit 151 of the mobile terminal 100 is in an inactive state. Can operate in a specific mode. This particular mode may be referred to as a 'doze mode'.

For example, in the dose mode, in a touch screen structure in which the touch sensor and the display unit 151 form a mutual layer structure, only a light emitting device for outputting a screen from the display unit 151 is turned off. The sensor may be in a state of maintaining an on state. Alternatively, the dose mode may be a mode in which the display unit 151 is turned off and the acceleration sensor is maintained in an on state. Alternatively, the dose mode may be a mode in which the display unit 151 is turned off and the touch sensor and the acceleration sensor are both turned on.

Therefore, in the dose mode state, that is, the display unit 151 is turned off, or the display unit 151 is turned off (the display unit 151 is deactivated), the user displays the display unit 151. When the tap is applied to at least one point on the screen or a specific point of the main body of the mobile terminal 100 or the display unit 151, the tab is removed from the user through at least one of a touch sensor or an acceleration sensor that is on. Can be detected.

In addition, the tap detector may determine that “tap” for controlling the mobile terminal 100 is detected only when at least two taps are applied within a reference time. For example, when a single tap is applied to the display unit 151 by a touch object capable of applying a touch to the display unit 151, the tap detector may recognize the single tap as a touch input. . That is, in this case, the controller 180 does not control a function corresponding to the one tap, but a function according to a touch input corresponding to the one tap (for example, outputted at a point where the touch input is applied). The ability to select an icon).

Therefore, the control unit 180 is a 'tap' for controlling one or more functions only when a tap is detected by at least two or more (or a plurality of) taps continuously applied within a reference time. It can be determined that it was detected.

That is, the tap gestures may mean that at least two or more tap gestures are continuously detected within a reference time. Accordingly, in the following description, "tap" detected may mean that an object such as a user's finger or a touch pen is touched on the main body or display unit 151 of the mobile terminal 100 a plurality of times. .

In addition, the controller 180 may determine whether the tap is detected not only within the reference time but also by the user's different finger or by one finger. For example, when the tabs are sensed by the display unit 151, the controller 180 determines whether the tabs are made through one finger or by using different fingers, respectively, by using a fingerprint detected in the portion where the taps are applied. Can be detected. Alternatively, the controller 180 recognizes the position where the taps are detected on the display unit 151 or the acceleration generated by the taps through at least one of a touch sensor and an acceleration sensor included in the tap sensing unit. It can be detected whether or through the fingers of each other or made through different fingers.

Further, the controller 180 further considers whether the user inputs the tabs through one hand or one finger or through both hands or at least two fingers, in consideration of the angle and distance at which the tab is applied or the direction in which the fingerprint is recognized. It can be determined whether or not the input.

The taps may mean a plurality of tappings that are continuously detected within a reference time. Here, the reference time may be a very short time, for example, a time within 300 ms to 2 s.

To this end, when it is detected that the mobile terminal 100 or the display unit 151 is first tapped for the tap detecting unit, the tap detecting unit may next tap after the first tap within a reference time from the time when the first tap is detected. Can detect if there is. When the next tap is detected within a reference time, the tap detector or the controller 180 may determine that a tap for controlling a specific function of the mobile terminal 100 is detected according to an embodiment of the present invention. have. As such, the controller 180 recognizes the user as a 'valid tap' only when the second tap is detected within a predetermined time after the first tap is detected, thereby determining whether the user wants to control the mobile terminal 100 or by mistake. You can tell if a tab is applied.

In addition, there may be a number of ways for the 'valid tap' to be recognized. For example, the controller 180 may tap the main body by the second reference number or the second reference number of times within a predetermined time after detecting the first tap that strikes the first reference number or the first reference number of times or more. This detection may be recognized as the 'valid tap'. Here, the number of the first reference number of times and the number of the second reference number of times may be the same or different. For example, the first reference number may be one time and the second reference number may be two times. As another example, both the first reference number and the second reference number may be one time.

In addition, the controller 180 may determine that the “taps” are detected only when the tap is applied within the “predetermined area”. That is, when it is detected that the main body of the mobile terminal 100 is first tapped, the controller 180 can calculate a predetermined area from the point where the first tap is detected. The controller 180 taps the first or second reference number of times or more than the first or second reference number of times in the “predetermined region” within the reference time from the time when the first tapping is detected. If is detected, it may be determined that the first tap or the second tap is applied.

On the other hand, the reference time and the predetermined region described above may be variously modified according to the embodiment.

Meanwhile, the first tap and the second tap may be sensed as separate taps according to the location where each tap is sensed, as well as the reference time and the predetermined area. That is, the controller 180 may determine that the first tap and the second tap are applied when the second tap is detected at a position spaced a predetermined distance or more from the position where the first tap is detected. In addition, when the first tap and the second tap are recognized based on the detected position, the first tap and the second tap may be sensed at the same time.

In addition, when the first tab and the second tab are configured with a plurality of touches, that is, a plurality of taps, a plurality of touches respectively constituting the first tab and the second tab may also be sensed at the same time. For example, while the first touch constituting the first tab is detected, the first touch constituting the second tab is located at a position spaced a predetermined distance or more from a position at which the first touch of the first tab is detected. If detected, the controller 180 can detect the first touch constituting the first tap and the second tap, respectively. The controller 180 detects an additional touch input detected at each location, and when the touch is detected at the first reference number or the second reference number of times at each location, the controller 180 determines that the first tap and the second tap are applied. can do.

On the other hand, when a tap for the main body or the display unit 151 of the mobile terminal 100 is detected from the tap detection unit a plurality of times, the controller 180 can execute the mobile terminal 100 based on the detected taps a plurality of times. At least one of the functions may be controlled.

For example, the controller 180 may control at least one of functions executable on the mobile terminal 100 when the plurality of taps correspond to a preset condition. For example, the controller 180 compares a plurality of preset touch input patterns with a pattern formed by the plurality of taps, and according to any one of the plurality of preset touch input patterns, You can release the lock. In this case, the controller 180 may perform any one function corresponding to the one touch input pattern.

Here, the function may mean all kinds of functions that can be executed or driven in the mobile terminal 100. For example, one of the functions may be an application installed in the mobile terminal 100. For example, 'an arbitrary function is executed' may mean that 'an arbitrary application is executed or driven in the mobile terminal 100'.

As another example, the function may be a function necessary for basic driving of the mobile terminal 100. For example, a function necessary for basic driving may be a function of turning on / off the lighting provided in the display unit 151, and switching the mobile terminal 100 from the unlocked state to the locked state or vice versa. There may be a function for switching to a released state, a function for setting a communication network, a function for changing setting information of the mobile terminal 100, and the like.

2 is a conceptual diagram illustrating the inside of a mobile terminal 200 according to an embodiment of the present invention, and FIG. 3A is a diagram conceptually illustrating an internal structure of the mobile terminal 200 illustrated in FIG. 2, and FIGS. 3B and FIG. 3C is a conceptual diagram illustrating the first space 200a and the second space 200b illustrated in FIG. 3A, respectively.

2 to 3C, the mobile terminal 200 includes a terminal body, a first speaker 210, a second speaker 220, and a partition 230.

Various components for implementing the mobile terminal 200 may be disposed in the internal space of the terminal body. The internal space may be equipped with a battery 290 for supplying power to the components as shown in FIG.

The first speaker 210 and the second speaker 220 are disposed to be spaced apart from each other in the internal space of the terminal body. In the drawing, the first and second speakers 210 and 200 are illustrated as disposed on the lower end of the terminal body, but may be disposed on the upper end of the terminal body or between the upper end and the lower end of the terminal body.

In general, a speaker is a device that converts a low frequency electric signal into a sound wave and reproduces it. The mobile terminal 200 of the present invention includes an audio channel composed of a plurality of speakers, and outputs different sound signals from each speaker to provide more three-dimensional sound.

The partition portion 230 is formed to partition the internal space into a first space 220a in which the first speaker 210 is disposed and a second space 220b in which the second speaker 220 is disposed. The resonance spaces for the respective acoustic signals output from the second speakers 210 and 220 are independently provided. The partition 230 may protrude from the bottom of the inner space. The resonance refers to a phenomenon in which the amplitude of an object increases because the frequency of a wave is the same as the natural frequency of another object.

The mobile terminal 200 may further include a first speaker hole 210a and a second speaker hole 220a.

The first speaker hole 210a and the second speaker hole 220a are formed on one surface of the terminal body, respectively, and communicate the first and second spaces 200a and 200b with the outside of the mobile terminal 200, respectively. It is formed to make. For example, the first speaker hole 210a and the second speaker hole 220a may be formed at lower ends of the main body of the terminal, as shown.

According to the present exemplary embodiment, the first and second spaces 200a and 200b are formed by the structure of the partition wall 230 that divides the internal space of the terminal body into the first space 200a and the second space 200b. The resonance space is provided for the first speaker 210 and the second speaker 220 respectively disposed in the first speaker 210, and the acoustic signals output through the first and second speakers 210 and 220 are respectively provided in the first and second spaces 200a,. Since the resonance is generated in each of (200b), it is possible to further improve the quality of the sound output through the mobile terminal 200.

[More details]

In addition, the sound signal resonated in the second space 220b after being output through the second speaker 220 is not only a second speaker hole 220a but also a receiver 252a disposed at an upper end of the terminal body. It can be output outside the main body. Accordingly, surround sound may be provided to the user through the receiver 252a and the second speaker hole 220a respectively positioned at the upper end and the lower end of the terminal body .

Meanwhile, the mobile terminal 200 may further include a packing part 240.

The packing part 240 is attached to the terminal body to block the first space 200a and the second space 200b from the outside, and together with the partition wall 230, the first and second spaces 200a, At least a portion of 200b). For example, the packing part 240 may be formed along the outer circumference of the terminal body. In addition, the packing part 240 may be configured to provide a dustproof and a waterproof function of the first and second spaces 200a and 200b.

According to such a configuration, the first and the second parts are formed by the packing part 240 attached to the terminal body to block the first space 200a and the second space 200b partitioned by the partition wall part 230 from the outside. As the shielding degree of the two spaces 200a and 200b is increased, noise affecting the acoustic signal output through the first speaker 210 and the second speaker 220 can be suppressed. As a result, the quality of sound output through the first and second speakers 210 and 220 may be further improved.

In addition, the partition 230 and the packing 240 may be formed as a seamless body (seamless body). Accordingly, the shielding effect on the first space 200a and the second space 200b can be further improved.

4A is a diagram conceptually illustrating an internal structure of a mobile terminal 200 according to another embodiment, and FIGS. 4B and 4C are diagrams illustrating a first space 200a and a second space 200b, respectively, shown in FIG. 4A. Conceptual diagram.
