The display unit 151 may operate as an entire area or may be divided into a plurality of areas and operated. In the latter case, the plurality of areas can be configured to operate in association with each other.

For example, an output window 151a and an input window 151b are displayed on the upper and lower portions of the display unit 151, respectively. In the input window 151b, a soft key 151c in which a number for inputting a telephone number or the like is displayed is output. When the soft key 151c is touched, a number corresponding to the touched soft key is displayed on the output window 151a. When the first operation unit 116 is operated, call connection to the telephone number displayed on the output window 151a is attempted.

When the soft keys 135c are touched through the touch pad 135, characters, numbers, symbols, etc. corresponding to the touched soft keys are displayed on the output window 135a. As described above, the touch input through the touch pad 135 is advantageous in that it is possible to prevent the soft key 135c from being covered by the finger when touching, compared with the touch input through the display unit 151. [ In the case where the display unit 151 and the touch pad 135 are formed to be transparent, the fingers located on the rear side of the terminal body can be visually confirmed, thereby enabling a more accurate touch input.

The display unit 151 or the touch pad 135 may be configured to receive a touch input by scrolling, as well as the input method described in the above embodiments. The user can move a cursor or a pointer located on an object displayed on the display unit 151, for example, an icon or the like, by scrolling the display unit 151 or the touch pad 135. [ Further, when the finger is moved on the display portion 151 or the touch pad 135, the path along which the finger moves may be visually displayed on the display portion 151. [ This will be useful for editing the image displayed on the display unit 151. [

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad 135 are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. The one function may be, for example, activation or deactivation of the display unit 151 or the touch pad 135, and the like.

The proximity sensor 141 described with reference to Fig. 1 will be described in more detail with reference to Fig.

4 is a conceptual diagram for explaining the proximity depth of the proximity sensor.

As shown in FIG. 4, when a pointer such as a finger of a user approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen detects the pointer and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to the distance between the proximity-touched pointer and the touch screen (hereinafter referred to as "proximity depth").

The distance at which the proximity signal is output when the pointer approaches the touch screen is referred to as a detection distance. The proximity signal output from each proximity sensor is simply used by using a plurality of proximity sensors having different detection distances, The depth is known.

In FIG. 4, for example, a cross-section of a touch screen having proximity sensors capable of sensing three proximity depths is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d ₀ ), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d ₁ , it is recognized as a proximity touch of the first proximity depth. If the pointer is located on the touch screen at a distance of d ₁ or more and less than distance d ₂ , it is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance of d ₂ or more and less than d ₃ distance, it is recognized as a proximity touch of the third proximity depth. If the pointer is located at a distance d ₃ or more on the touch screen, it is recognized that the proximity touch is released.

Accordingly, the controller 180 can recognize the proximity touch as various input signals according to the proximity and proximity positions of the pointer to the touch screen, and perform various operation controls according to the various input signals.

Hereinafter, embodiments of the present invention will be described. In the present invention, the display unit 151 is assumed to be the touch screen 151 for convenience of explanation. As described above, the touch screen 151 can perform both the information display function and the information input function.

The audio control method of the mobile terminal according to the embodiment of the present invention can be implemented in the mobile terminal 100 described with reference to FIG. 1 to FIG. Hereinafter, an audio control method of a mobile terminal according to an embodiment of the present invention and an operation of the mobile terminal 100 for implementing the audio control method will be described in detail with reference to FIG. 5 and necessary drawings.

The mobile terminal 100 may provide a call function and a broadcast reception function as described above. The call function includes at least one of a call origination function and a call reception function.

The control unit 180 may receive a broadcast including the first audio signal (S100). In step S100, the control unit 180 may receive the broadcast through the broadcast receiving module 111 or the wireless Internet module 113. [ The broadcast received in step S100 may include not only the first audio signal but also a video signal and a data signal. Herein, it is assumed that the broadcast received in step S100 includes the first audio signal and the video signal.

The controller 180 outputs the first audio signal through the audio output unit 152 (S110). For example, referring to FIG. 8, the control unit 180 receives a broadcast through channel 06, outputs a video signal through the display unit 151, and outputs the video signal through the audio output unit 152 1 audio signal.

The control unit 180 starts the call function (S120). The start of the call function means an initial operation of receiving a call from the outside or sending a call to the outside. The call function may be performed using the mobile communication module 112 or the wireless Internet module 113. [ Hereinafter, embodiments of the present invention will be described assuming that a call is received from the outside of the call functions provided by the mobile terminal 100. [

FIGS. 9A and 9B, FIGS. 10A and 11A show examples of screens displayed according to an embodiment of the present invention when a call is received from the outside.

In the present invention, a text mode and an audio mode are provided as described later. The text mode and the voice mode may be applied when the call function and the broadcast receiving function are simultaneously performed. The text mode and the voice mode may be preset to be automatically performed or may be manually selected by the user whenever the call function and the broadcast receiving function are simultaneously performed.

Broadcast content in general can include audio information and video information. In particular, when a call function such as receiving a call or calling a call is performed while the mobile terminal 100 is receiving broadcast content including audio information, audio information included in the broadcast content, The audio information (for example, the other party's voice) received from the other party may be mixed. According to the embodiments of the present invention described below, the mobile terminal 100 changes the audio information included in the broadcast content and the audio information received at the time of performing the call function into text information, ). A mode in which the audio information included in the broadcast content is changed to text information is referred to as the voice mode and a mode in which the audio information received in performing the call function is changed to text information is referred to as the text mode. The details of the text mode and the voice mode will be described later.

If the call function and the broadcast receiving function are simultaneously performed, the control unit 180 determines whether one of the text mode and the voice mode is set to be performed automatically (S130). If the automatic execution is set as a result of the determination in step S130, the controller 180 determines whether the automatic mode is set to the text mode (step S140). If the automatic mode is set to the text mode, the controller 180 performs the text mode as described below (see FIG. 6). Alternatively, if it is determined in step S140 that the automatic mode is not the text mode, the controller 180 performs the voice mode as described below (see FIG. 7).

For example, FIG. 9A shows an example of a screen in which the voice mode is set to be performed automatically. 9A, when a call is received from "Hong Kil Dong" while receiving a broadcast corresponding to "CH 06 ", the controller 180 notifies the user of the call reception through the first pop-up window 20a Informs the user that the current "voice mode" is set via the first pop-up window 20a.

For example, FIG. 9B shows an example of a screen in which the text mode is set to be performed automatically. 9B, when a call is received from "Hong Kil-dong" while receiving a broadcast corresponding to "CH 06 ", the controller 180 notifies the user of the call reception through the second pop-up window 20b Quot; text mode "is set through the second pop-up window 20b.

The first pop-up window 20a and the second pop-up window 20b correspond to a user interface (UI) or a graphical user interface (GUI).

9A and 9B, the user can reject the call by starting the call by the voice mode by selecting the call start icon 21, or by selecting the call end icon 22. The user can select the call start icon 21 or the call end icon 22 by touching the call start icon 21 with a finger or a stylus pen.

On the other hand, if it is determined in step S130 that the text mode or the voice mode is not automatically performed, the controller 180 may select one of the text mode and the voice mode A user interface can be provided [S150]. The provision of the user interface is performed corresponding to the start of the call function.

10A and 11A show an example of providing the selection user interface 20c. Fig. 10A shows a case where the user selects "text mode ", and Fig. 11A shows a case where the user selects" voice mode ".

The control unit 180 receives a selection signal for selecting one of the text mode and the voice mode through the selection user interface 20c (S160). If the received selection signal indicates that the text mode is selected (S170). If it is determined in step S170 that the received selection signal is the text mode, the controller 180 performs the text mode as described below (see FIG. 6). If the received selection signal is the voice mode, the controller 180 performs the voice mode as described below (see FIG. 7).

Hereinafter, the text mode and the voice mode according to the embodiment of the present invention will be described in detail. First, the text mode will be described with reference to FIG. 6 and necessary drawings.

The control unit 180 converts the second audio signal (or the voice of the other party) received from the outside through the mobile communication module 112 or the wireless Internet module 113 into text by starting the call function [ S200]. The mobile terminal 100 may include a voice / text conversion module that converts voice to text (Speech To Text (STT)) and converts text to voice (Text To Speech).

The control unit 180 displays the converted text on the display unit 151 in step S200 and outputs the first audio signal included in the received broadcast through the audio output unit 152 [S210]. Accordingly, the user can hear the audio information included in the broadcast through the sound output unit 152, and the voice of the other party can be converted into text and viewed through the display unit 152. [

When the call reception function and the call origination function are performed, it is general that not only the voice of the other party but also the user of the mobile terminal 100 transmits voice information to the other party.

In this document, the information that the user of the mobile terminal 100 wants to transmit to the other party can be transmitted in the form of audio information (for example, user's voice). Here, the user may input voice through the microphone 122 or input text through the user input unit 130 or the touch screen 151 (S220).

When the voice is input, the control unit 180 transmits the input voice to the other party through the mobile communication module 112 or the wireless Internet module 113. If the text is input, the control unit 180 converts the input text into voice using the voice / text conversion module (S230) and transmits the voice to the other party (S240).

For example, referring to FIGS. 10B and 10C, the controller 180 converts the voice received from the opposite party of the call currently being executed into text into a first text display area 31, A virtual keyboard 30 for receiving text from a user of the mobile terminal 100 may be provided to the touch screen 151. [ The text (corresponding to "I") input through the virtual keyboard 30 can also be displayed in the first text display area 31. [

10B and 10C show examples of different screen configurations, respectively. For example, in the case of FIG. 10B, the virtual keyboard 30 is provided transparently or semi-transparently over an image included in a broadcast currently being received. For example, in the case of FIG. 10C, an area 35 in which an image included in a broadcast currently being received is displayed and an area in which the virtual keyboard 30 is provided are provided separately. In the case of FIG. 10C, the image included in the broadcast may be smaller in size than the image before the start of the call function.

Meanwhile, the text mode may be converted into the voice mode while the broadcast receiving function and the call function are simultaneously performed. The conversion from the text mode to the voice mode may be performed in various ways.

For example, the selection user interface provided in step S150 described above may be continuously provided while the broadcast receiving function and the call function are simultaneously performed. For example, referring to FIG. 10B, the selection user interface 32 may be provided on the touch screen 151 in the form of an icon. When the user selects the first icon 32 by touching the first icon 32 with a finger or a stylus pen, the text mode currently being performed can be converted to the voice mode.

Also, for example, a conversion function from the text mode to the voice mode may be assigned to a specific key button included in the user input unit 130. [ The user can switch between the text mode and the voice mode by pressing the specific key button.

That is, the controller 180 determines whether the voice mode is changed during the text mode operation (S250). If the voice mode is changed, the controller 180 performs the voice mode (refer to FIG. 7) .

The controller 180 determines whether the call currently being executed is terminated at step S260. When the call is terminated, the controller 180 displays the virtual keyboard 30 and the first text display area 31 on the display unit 151, And returns to the screen configuration of FIG.

Hereinafter, the voice mode will be described with reference to FIG. 7 and the necessary drawings.

Under the voice mode, the control unit 180 performs a call with the other party by voice (S300). Calling by voice is a method of outputting a voice received from the other party through the sound output unit 152 and transmitting a voice input from the user of the mobile terminal 100 through the microphone 122 to the other party It says.

The control unit 180 converts the first audio signal included in the received broadcast into text using the voice / text conversion module [S310], and converts the text converted in step S310 to the display unit 151 (S320). Referring to FIG. 11B, a second text display area 37 in which audio information included in a broadcast is converted into text and displayed is provided.

As described in the text mode, the voice mode can also be converted to the text mode by various methods. For example, a second icon 38 may be provided on the touch screen 151 to which the function of converting the voice mode into the text mode is assigned. If the user selects the second icon 38 by touching it with a finger or a stylus, the currently performed voice mode may be converted to the text mode. Also, for example, as described in the text mode, the text mode can be converted from the voice mode to the text mode by selecting the specific key button included in the user input unit 130. [

That is, the controller 180 determines whether the text mode is changed during the speech mode (S330). If the text mode is changed, the controller 180 performs the text mode (see FIG. 6) .

8, the control unit 180 determines whether the current call is terminated at step S340. When the call ends, the second text display area 37 is removed from the display unit 151, The audio output unit 152 outputs the first audio signal included in the received broadcast.
