A mobile terminal 100 according to a first exemplary embodiment of the present invention is a folder type mobile terminal, as shown in FIG. 1 and FIG. 2, and includes a first body unit 10, a second body unit 20, and a hinge unit 30. The first body unit 10 has an inside surface 11, an outside surface 13 facing the inside surface 11, and dual speakers 15 respectively installed in opposite end parts of the inside surface 11. The second body unit 20 is installed above the inside surface 11 of the first body unit 10 inside of the dual speakers 15, and has a first display unit 25 installed in an outside surface 23 opposite to an inside surface 21 facing the inside surface 11 of the first body unit 10. The hinge unit 30 connects the first body unit 10 and the second body unit 20, and opens/closes the second body unit 20 with respect to the first body unit 10. Here, the hinge unit 30 connects one end part of the second body unit 20 adjacent to one of the dual speakers 15 and one end part of the first body unit 10.
The dual speakers 15 of the first body unit 10 are installed outside of opposite end parts, that is, opposite short side edge parts of the first display unit 25. Thus, when a user wants to use the first display unit 25 in a landscape mode, a user may turn the mobile terminal 100. In this case, since the dual speakers 15 are positioned outside of the opposite end parts of the first display unit 25, the user may listen to high quality sound output through the dual speakers 15.
The first body unit 10 includes a keypad 17 and a microphone 19 that are installed in the inside surface 11 thereof. When the second body unit 20 is closed, the keypad 17 and the microphone 19 are covered by the second body unit 20, and thus, the keypad 17 and the microphone 19 are not exposed. When the second body unit 20 is opened, the keypad 17 and the microphone 19 are exposed.
The second body unit 20 includes a second display unit 27 installed in the inside surface 21 thereof. That is, the second body unit 20 has two display units 25 and 27. The second body unit 20 includes an earpiece 29 that is installed opposite to the hinge unit 30. In particular, the second body unit 20 is shorter than the first body unit 10 and is installed in a central part of the inside surface 11 of the first body unit 10, which provides a floating effect in which the first display unit 25 appears to float.
The two display units 25 and 27 may be liquid crystal displays (LCDs), however, other display devices such as active matrix organic light emitting diodes (AM OLEDs) may be used. The first display unit 25 installed in the outside surface of the mobile terminal 100 may have a relatively big screen and relatively good resolution, compared with the second display unit 27. For example, the first display unit 25 may be embodied as a large-sized quarter video graphics array (QVGA) LCD and the second display unit 27 may be embodied as a small-sized quarter common intermediate format (QCIF) LCD. However, the present invention is not limited thereto, and thus, the two display units 25 and 27 may have the same size and resolution.
The first display unit 25 may provide a multimedia mode to display a screen of multimedia functions such as digital broadcasts, moving pictures, or MP3 services; and the second display unit 27 may provide a communication mode to display a screen of typical functions such as communication. Further, when displaying a screen, the first display unit 25 may provide a landscape mode, and the second display unit 27 may provide a portrait mode. However, the two display units 25 and 27 are not limited to the above-described modes.
Screens of the two display units 25 and 27 are not turned on simultaneously. In other words, if one of the display units is turned on, the other may be turned off.
In particular, when the first display unit 25 is activated to perform a multimedia mode when the second body unit 20 is closed, the dual speakers 15 are activated. Accordingly, a user may watch an image displayed on the first display unit 25 and listen to high quality sound output through the dual speakers 15 installed outside of the opposite end parts of the first display unit 25.
Further, when the second display unit 27 is activated to perform a communication mode when the second body unit 20 is opened, the earpiece 29 and the microphone 19 are activated.
Since the second body unit 20 having the two display units 25 and 27 is installed in the central part of the first body unit 10, and the dual speakers 15 are exposed outside of the opposite end parts of the second body unit 20, the second body unit 20 may float or protrude with respect to the first body unit 10. Accordingly, when watching digital broadcasts or moving pictures on the first display unit 25, the user may focus on the first display unit 25.
Further, since the dual speakers 15 are arranged in the opposite end parts of the first body unit 10, the weight thereof may be stably distributed in the first body unit 10, and accordingly the user may stably manipulate the mobile terminal 100 while holding the mobile terminal 100.
As described above, since the second body unit 20 having the first display unit 25 is installed in the central part of the first body unit 10, and is shorter than the first body unit 10, the mobile terminal 100 according to the first exemplary embodiment of the present invention may provide a floating effect in which the first display unit 25 appears to float. Thus, the digital broadcasts or moving pictures displayed on the first display unit 25 may be distinct, and the user may focus on an image displayed on the first display unit 25.
Further, in the mobile terminal 100 according to the first exemplary embodiment of the present invention, since the dual speakers 15 are exposed in the same direction as the first display unit 25, an image display direction of the first display unit 25 and a sound output direction through the dual speakers 15 are the same. Accordingly, when the second body unit 25 is closed, the user can watch an image displayed through the first display unit 25 and listen to high quality sound output through the dual speakers 15, in the same direction.
A mobile terminal 200 according to a second exemplary embodiment of the present invention is a slide type mobile terminal, as shown in FIG. 3 and FIG. 4, and includes a first body unit 110, a second body unit 120, and a hinge unit 130. The first body unit 110 has an inside surface 111, an outside surface 113 opposite to the inside surface 111, and dual speakers 115 installed in opposite end parts of the inside surface 111. The second body unit 120 is installed above the inside surface 111 of the first body unit 110 inside of the dual speakers 115, and has a display unit 125 installed in an outside surface 123 opposite to an inside surface 121 facing the inside surface 111 of the first body unit 110. The hinge unit 130 connects the first body unit 110 and the second body unit 120, and opens/closes the second body unit 120 with respect to the first body unit 110. The hinge unit 130 has a sliding hinge to open/close the second body unit 120 by translating the second body unit 120 in a lengthwise direction of the first body unit 110.
Since the second body unit 120 having the display unit 125 is installed in a central part of the first body unit 110, and is shorter than the first body unit 110, the mobile terminal 200 according to the second exemplary embodiment of the present invention may provide a floating effect in which the display unit 125 appears to float. Accordingly, digital broadcasts or moving pictures displayed through the display unit 125 may be distinct, and thus, a user may focus an image displayed on the display unit 125.
Further, in the mobile terminal 200 according to the second exemplary embodiment of the present invention, since the dual speakers 115 are exposed in the same direction as the display unit 125, an image display direction on the display unit 125 and a sound output direction through the dual speakers 115 may be the same. Accordingly, when the second body unit 120 is closed, the user may watch an image displayed through the display unit 125 and listen to high quality sound output through the dual speakers 115, in the same direction.
The dual speakers 115 of the first body unit 110 are installed outside of opposite end parts, that is, opposite short side edge parts of the display unit 125. Thus, when a user wants to use the display unit 125 in a landscape mode, the user may turn the mobile terminal 200. In this case, since the dual speakers 115 are positioned outside of the opposite end parts of the display unit 125, the user may listen to high quality sound output through the dual speakers 115.
A keypad 117 and a microphone 119 are installed in the inside surface 111 of the first body unit 110. The keypad 117 and the microphone 119 are covered by the second body unit 120 and are not exposed when the second body unit 120 is closed. The keypad 117 and the microphone 119 are exposed when the second body unit 120 is opened.
The display unit 125 of the second body unit 120 is typically embodied as an LCD, however other display devices such as an AM OLED may be used. The second body unit 120 may include an earpiece 129 installed in an end part of the outside surface 123 thereof, outside of the display unit 125.
In particular, when the display unit 125 is activated to perform a multimedia mode when the second body unit 120 is closed, the dual speakers 115 are activated. Accordingly, the user may watch an image displayed through the display unit 125 and listen to high quality sound output through the dual speakers 115, in the same direction.
When the display unit 125 is activated to perform a communication mode in the state that the second body unit 120 is opened, the earpiece 129 and the microphone 119 are activated.
Since the second body unit 120 having the display unit 125 is installed in the central part of the first body unit 110 and the dual speakers 115 are exposed outside of the opposite end parts of the second body unit 120, the second body unit 120 may appear to float or protrude with respect to the first body unit 110. Accordingly, when watching digital broadcasts or moving pictures on the display unit 125, the user may focus on the display unit 125.
Since the dual speakers 115 are arranged in the opposite end parts of the first body unit 110, the weight thereof may be stably distributed in the first body unit 110, and accordingly, the user may stably manipulate the mobile terminal 200 when holding the mobile terminal 200.
It will be apparent to those skilled in the art that various modifications and variation can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
