3A and 3B are front views of a portable terminal for explaining an operation state of the portable terminal related to the present invention.

Various types of time information can be displayed on the display unit 151. [ These pieces of information can be displayed in the form of letters, numbers, symbols, graphics, or icons.

At least one of the letters, numbers, symbols, graphics, or icons may be displayed in a predetermined arrangement for inputting such information, thereby being implemented as a keypad. Such a keypad may be called a so-called " soft key ".

FIG. 3A shows a touch input to a soft key through a front surface of a terminal body.

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. The output window 151a and the input window 151b are areas allocated for outputting or inputting information, 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 131 is operated, call connection to the telephone number displayed on the output window 151a is attempted.

FIG. 3B shows the input of a touch applied to the soft key through the rear surface of the terminal body. FIG. 3A shows a case where the terminal body is vertically arranged, and FIG. 3B shows a case where the terminal body is arranged horizontally. The display unit 151 may be configured to convert an output screen according to a placement direction of the terminal body.

3B shows that the text input mode is activated in the portable terminal. The display unit 151 displays an output window 151a 'and an input window 151b'. In the input window 151b ', a plurality of soft keys 151c' displayed with at least one of letters, symbols, and numbers may be arranged. The soft keys 151c 'may be arranged in the form of a QWERTY key.

When the soft keys 151c 'are touched through the touch pad 135 (see FIG. 2B), characters, numbers, symbols corresponding to the touched soft keys are displayed on the output window 151a'. As described above, the touch input through the touch pad 135 is advantageous in that the soft key 151c 'can not be blocked by the finger when the touch is input, 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 unit 151 or the touch pad 135, the path along which the finger moves may be visually displayed on the display unit 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 activation or deactivation of the display unit 151 or the touch pad 135, for example.

FIG. 4 is an exploded perspective view of a portion referred to as the display portion 151 of FIG. 2A. The film speaker 200 and the touch sensor 136 are combined with the display 151a. For convenience, these components are referred to as a display 151 in the drawings.

Referring to this figure, the display 151a outputs time information as described above. Display 151a has generally rectangular shaped surfaces. Since the time information is outputted through one of the above main surfaces, this surface is referred to as an output surface 151b.

A film speaker 200 is attached to the output surface 151b of the display 151a. The film speaker 200 has a thin film shape such as a film, for example, a speaker made by adding an electrode material containing sound information to a PVDF film used as a finish material for an automobile dashboard. When the current is applied to the PVDF film, the electrode is moved, and the sound is output as the film vibrates. The sound quality of current products can range from 200Hz up to 20,000Hz, which is almost the same as that of a regular magnet type speaker. In addition, since the film speaker can be made transparent in the form of ultra-thin film of, for example, 0.08 mm, interference with the image output from the display 151a hardly occurs even if it is attached to the display 151a.

A spacer 201 may be disposed between the film speaker 200 and the display 151a in order to secure a space for resonance when the film speaker 200 vibrates. The spacer 201 serves to separate the film speaker 200 and the display 151a by a predetermined distance. The space defined by the film speaker 200, the display 151a, and the spacer 201 serves as a space for the above resonance.

A touch sensor 136 may further be disposed between the film speaker 200 and the display 151a. The touch sensor 136 is a sensor constituting the user input unit 130 (FIG. 1) like the touch pad 135 (FIG. 2B), and recognizes the user's touch operation. In this arrangement, the user touches the film speaker 200, and the touch sensor 136 recognizes such touch operation.

In this case, the touch sensor 136 and the film speaker 200 are formed in a light transmission type so that time information output from the display 151a can be recognized from the outside.

The structure may be such that the film speaker 200 is first coupled to the display 151a and the touch sensor 136 is coupled to the film speaker 200, unlike the arrangement structure of this embodiment. Further, the film speaker 200 and / or the touch sensor 136 may be disposed on a surface opposite to the output surface 151b of the display 151a. When the touch sensor 136 is disposed on the opposite side of the output surface 151b, the touch pad 135 of FIG. 3B may be used. In this case, there is an advantage that the display 151a or the film speaker 200 does not receive interference when the touch pad 135 is operated.

FIG. 5 is a conceptual diagram for explaining the operation of the film speaker 200 of FIG.

Referring to this figure, the film speaker 200 includes a plurality of operating areas 210 and 220. These operating regions 210 and 220 can be controlled to operate in different ways. This type of control for the film speaker 200 is performed by the control unit 180 (FIG. 1).

In the figure, the operating regions 210 and 220 are illustratively divided into a first region 210 and a second region 220. In this embodiment, the operating regions 210 and 220 may all output sound, but may be configured to selectively output sound. For example, the first area 210 may be a sound output area, while the second area 220 may be a sound output area.

The operating regions 210 and 220 are differently operated not only in terms of whether or not the sound is output, but also in terms of the content of the sound to be output, the output speed of the sound, the output timing of the sound, the output volume, and the continuity of the sound output. . For example, when a foreign currency is output from the display 151a, the first region 210 outputs a foreign language used in the foreign currency, and the second region 220 outputs Korean dubbed. In this case, it can be said that the contents of sounds output from the respective operation regions 210 and 220 are different. Even if the sound of the same content is output, if the first region 210 outputs sound before the second region 220 for a certain period of time, the sound output timing may be different. Furthermore, any one of the operating regions 210 and 220 may output sound at a volume greater than the other. Also, when sound is output at a normal playback speed in any one of the operation regions 210 and 220, sound may be output at a speed several times faster or slower in the other one.

Referring again to FIG. 5, even when the first area 210 outputs sound, the detail areas among them, for example, the 1-1 zone 211 through the 1-4 zone 214, The output of the form can be done. For example, the output volumes of the areas 211 to 214 may be different from each other or different from each other.

FIG. 6 is a conceptual diagram for explaining the operation of the film speaker 200 according to the modification of FIG.

Referring to this figure, a first region 210 for outputting sounds is arranged along the diagonal line of the film speaker 200. The first region 210 may be divided into the 1-1 region 211 to the 1-4 region 214 as described above.

The first-first region 211 to the first-fourth region 214 may operate so that the sound output from them forms a constant pattern. For example, after the sound is output in the 1-1 zone 211, the sound is output sequentially to the 1-2 zone 212, the 1-3 zone 213, and the 1-4 zone 214 Sound may be output. For example, when a bullet is continuously fired in a movie output from the display 151a, a pattern corresponding to a sound pattern corresponding to a difference in launch timing of bullets and a position where the sounds are output varies. If the user is in a position closer to the first-second area 211 than the other areas 212 to 214, the above-described output pattern may give a louder sound.

On the contrary, if sounds are output sequentially from the 1-4 region 214 to the 1-1 region 211, the user may feel that the sound approaches to the user by moving the region where the sound is output .

The position of the user can be recognized by the sensing unit 140 (FIG. 1) that senses the posture of the main body. When the sensing unit 140 transmits the sensed result of the attitude of the main body to the control unit 180, the control unit 180 controls the operating regions 210 and 220 of the film speaker 200, And controls the 1-1 to 1-4 areas 211 to 214 of the area 210.

7 is a perspective view of the portable terminal 100 for explaining another modification of FIG.

Referring to this figure, in the case of a telephone call, the film speaker 200 can replace the sound output unit 152 (FIG. 2A). Accordingly, the acoustic output section 152 is not shown in this drawing.

Sound may be output in the entire area of the film speaker 200 during a telephone conversation, but it is preferable that the sound output is performed only in a region close to the user's ear, considering the position of the sound output unit 152. [

In the latter case, as the sensing unit 140 senses the attitude of the main body, the control unit 180 can set the area 210 near the user's ear as a sound output area. Thereby, it is possible to prevent sound from being output in the region 220 other than the upper region 210.

Furthermore, it is possible to set the farthest region along the longitudinal direction of the main body from the microphone 122 (Fig. In this case, the specific region is set as the first region 210 regardless of the attitude of the main body.

FIG. 8 is a perspective view illustrating an operation of the portable terminal 100 having the film speaker 200 and the touch sensor 136 of FIG.

Referring to this figure, while the entirety of the plurality of operating regions 210 and 220 of the film speaker 200 output sound, the user can touch one region 210 to operate the touch sensor 136 have.

In this case, the touched area 210 is controlled to stop outputting sound. Even in this case, the peripheral area 220 continues to output sound. This can prevent the touch area 210 of the film speaker 200 from vibrating due to a user's touch, thereby preventing a trouble in outputting the sound. Therefore, even if the film speaker 200 is pressed to operate the touch sensor 136, the possibility that the film speaker 200 outputs an incomplete sound as a whole is lowered.

Alternatively, if the touchpad 135 (FIG. 2B) is used without the touch sensor 136 and the film speaker 200 and the touchpad 135 are arranged symmetrically with respect to the display 151a, Will almost disappear. Further, even when the touch sensor 136 operates as the proximity sensor 141 (Fig. 1), the problem caused by the pressing of the film speaker 200 can be substantially eliminated.

FIG. 9 is a perspective view of a portable terminal 100 for explaining a modification of FIG.

Referring to FIG. 2, the film speaker 200 may output sound in the touched area 210 in order to perform a touch operation on the user touch sensor 136.

For example, with the display 151a outputting the world map, the user can touch the region 210 'occupied by Korea. In this case, the region 210 'corresponding to the South Korea can output a Korean greeting such as' Hello'. In this case, the remaining areas do not output sound. When the user touches the region 210 "occupied by the United States, a greeting called" Good Morning "may be output only in the upper region 210". Accordingly, the user can memorize the location of the country in the world map and the greetings in a more stereoscopic manner by sound output from the regions 210 'and 210 "corresponding to the position of the corresponding country.

In the present embodiment, the upper areas 210 'and 210 "are illustrated as outputting the greeting, but the areas 210' and 210" may output other information such as the current time of the corresponding country.

10 is a perspective view of the portable terminal 100 for explaining another modification of FIG.

Referring to the drawing, a user can touch the left bottom area while sound is output in the entire area of the film speaker 200. Thereby, the output of the sound in the left lower end region 210 is stopped.

In addition, when the user moves the finger touched to the upper right area to perform the drag operation, the area 210 in which the sound is not output is expanded based on the upper direction. On the contrary, the region 210 for outputting sound is reduced to only the upper left region in the entire region of the film speaker 200, except for the lower right end region. This can lead to a result that the overall output volume of the film speaker 200 becomes small.

 Correspondingly, the display 151a can visually output the boundary lines 151c and 151c 'of the area 220 in which the sound is output. By such a visual display, the user can visually recognize a change in the volume due to the dragging.

11 is a perspective view for explaining the operation of the portable terminal 100 according to the modification of FIG.

Referring to this figure, the display 151a is divided into a plurality of screens 151-1 and 151-2, and can be configured to output substantially different contents, respectively. For example, in the left screen 151-1, an image relating to the other party to be video telephony is output, and a music playback screen is output in the right screen 151-2.

In this case, the voice of the other party is output in the first area 210 of the film speaker 200 corresponding to the left screen 151-1, and the voice of the other speaker of the film speaker 200 corresponding to the right screen 151-2 In the second area 220, sound corresponding to music reproduction may be output.

When the user feels trouble interfering with the voice of the other party making a video call by sound according to music playback, the user touches the touch sensor 136 to recognize dragging along one direction (direction from right to left) . In this case, the volume of the first area 210 may be increased, and conversely, the volume of the second area 220 may be lowered.

12 is a perspective view for explaining a portable terminal 100 in which the display 151a and the film speaker 200 are installed in a manner different from that of FIG. 2A, and FIG. 13 is a partial cross-sectional view for explaining the outlet 101a of FIG. 12 .

Referring to FIG. 12, the film speaker 200 and the display 151a are formed as a flexible material. Thereby, the film speaker 200 and the display 151a can be wound inside the main body of the portable terminal 100 and stored or loosened, and can be taken out to the outside.

On one side of the main body, an outlet 101a for drawing out the film speaker 200 and the display 151a is formed. An internal space for accommodating the film speaker 200 and the display 151a is formed in the main body and a rod for winding the film speaker 200 and the display 151a is formed in a part of the internal space, An elastic body for elastically rotating the rod, for example, a torsion spring is provided. The upper rod and the elastic body are indicated by a winding part 230 in this drawing.

The display 151a and the film speaker 200 output video and sound only in the area A corresponding to the area indicated by the display part 151 while being accommodated in the main body, ) Can also output images and sounds.

And another display fixed separately from the fetchable display 151a may be additionally provided. The display 151a may be overlapped with other displays in a state where the display 151a is accommodated in the main body, but may be arranged in parallel with other displays in a state of being drawn out to realize two display areas.

Referring to FIG. 13, the front case 101 of the main body is formed with a locking portion 101b protruding toward the upper internal space. A hook 240 is formed on the display 151a and the film speaker 200 so as to catch the hooking portion 101b.

After the display 151a and the film speaker 200 are pulled out against the elastic force of the winding part 230, the hook 240 is hooked on the hook part 101b. Thereby, the display 151a or the like which is exposed to the outside maintains its position. When the display 151a or the like is to be accommodated in the main body, the hooks 240 may be separated from the latching portion 101b by operating the display 151a or the like in the downward direction in the drawing. By the elastic force of the winding part 230, the display 151a or the like is wound and accommodated in the main body.

FIG. 14 is a perspective view of the portable terminal 100 for explaining an operation method of the film speaker 200 of FIG.
