The folder opening/closing detection module 180 detects the states of the folder housings of the wireless terminal and outputs folder opening/closing detection signals to the control module 110. In other words, the folder opening/closing detection module 180 detects the folder opening/closing detection signals according to the states of the folder housings of the wireless terminal and outputs the folder opening/closing detection signals to the control module 110. Herein, the folder opening/closing detection module 180 may be realized in various ways. For example, it is assumed that, according to an embodiment of the present invention, the folder opening/closing detection module 180 comprises sensors (making contact with the first folder housing and the second folder housing when they are closed) disposed in the body housing of the wireless terminal and magnets fixed to the first folder housing and the second folder housing of the wireless terminal, respectively, thereby detecting four folder opening/closing states of the folder housings caused by the magnets detected by the sensors. In addition, it is assumed that the folder opening/closing sensors are hall effect ICs. The locations and the number of the sensors and the magnets, which have been optionally selected in the above-described embodiment, are not fixed but may change according to the type of portable terminals used.
Hereinafter, four folder opening/closing detection signals detected by the folder opening/closing detection module 180 will be described with reference to FIGS. 2A to 2D.

In the first folder opening/closing state shown in FIG. 2A, if the sensor (not shown) disposed in the body housing of the wireless terminal, which makes contact with the first folder housing, detects the magnet included in the first folder housing, and if the sensor (not shown) disposed in the body housing of the wireless terminal, which makes contact with the second folder housing, detects the magnet (not shown) included in the second folder housing, the folder opening/closing detection module 180 generates a first folder opening/closing detection signal.
In the second folder opening/closing state shown in FIG. 2B, if the sensor (not shown) disposed in the body housing of the wireless terminal, which makes contact with the second folder housing, detects the magnet (not shown) disposed in the second folder housing, the folder opening/closing detection module 180 generates a second folder opening/closing detection signal.
In the third folder opening/closing state shown in FIG. 2C, if the sensor (not shown) disposed in the body housing of the wireless terminal, which makes contact with the first folder housing, detects the magnet (not shown) included in the first folder housing, the folder opening/closing detection module 180 generates a third folder opening/closing detection signal.
In the fourth folder opening/closing state shown in FIG. 2D, if the sensor (not shown) disposed in the body housing of the wireless terminal, which makes contact with the first folder housing, does not detect the magnet included in the first folder housing, and if the sensor (not shown) disposed in the body housing of the wireless terminal, which makes contact with the second folder housing, does not detect the magnet (not shown) disposed in the second folder housing, the folder opening/closing detection module 180 generates a fourth folder opening/closing detection signal.
The position detection module 190 detects a position of the wireless terminal and outputs a position detection signal to the control module 110. Specifically, the position detection module 190 detects position detection signals according to positions of the wireless terminal so as to output the position detection signals to the control module 110. Herein, according to an embodiment of the present invention, it is assumed that the position detection module 190 is a two-axis acceleration sensor capable of detecting an X axis and a Y axis.
Hereinafter, two position detection signals detected by the position detection module 190 will be described with reference to FIGS. 6A to 9B. FIGS. 6A and 6B are views illustrating an operation of the wireless terminal according to the position detection signals in the first folder opening/closing state. FIG. 6A shows a first position state in the first folder opening/closing state of the wireless terminal, and FIG. 6B shows a second position state in the first folder opening/closing state. Herein, the first position state refers to a state in which the wireless terminal stands upright, and the second position state refers to a state in which the wireless terminal has been rotated 180° from the first position state. FIGS. 7A and 7B are views illustrating an operation of the wireless terminal according to the position detection signals in the second folder opening/closing state.

If the wireless terminal is in an upright position as shown in FIGS. 6A, 7A, 8A, and 9A, the position detection module 190 generates the first position detection signal.
In addition, if the wireless terminal has been rotated 180° as shown in FIGS. 6B, 7B, 8B, and 9B, the position detection module 190 generates the second position detection signal.
FIG. 3 is a flowchart illustrating a method for controlling functions of the display module and the key input modules in the wireless terminal according to an embodiment of the present invention. Specifically, a method for controlling the functions of the display module 160 and the key input module 170 in the wireless terminal including the folder opening/closing detection module 180 shown in FIGS. 2A to 2D will be described below with reference to FIG. 3. According to an embodiment of the present invention, it is assumed that the inner keys and the external keys of the first key input module 171 are realized as alphanumeric keys for inputting numeral information and letter information. In addition, it is assumed that the inner keys and the external keys of the second key input module 172 are realized as function keys for setting various functions.
Referring to FIG. 3, the control module 110 determines whether or not the current mode is a display mode in step 301. Herein, the display mode refers to a mode in which an image is displayed on the first display module 161 due to contact of the body housing and the folder housings in the wireless terminal. In addition, the display mode refers to a mode in which an image is displayed on the second display module 162 due to separation between the body housing and the folder housings in the wireless terminal. If an automatic display change mode is set in the display mode described above, the control module 110 detects the automatic display change mode in step 302. Herein, the automatic display change mode refers to a mode in which the functions of the display module 160 and the key input module 170 are controlled according to the folder opening/closing detection signals of the folder opening/closing detection module 180. Accordingly, if the automatic display change mode is not set, the control module 110 allows the display module 160 and the key input module 170 to perform their general functions regardless of an output of the folder opening/closing detection module 180. However, if the automatic display change mode is set, the control module 110 determines whether the folder opening/closing detection signals are output from the folder opening/closing detection module 180. If the folder opening/closing detection signals are output from the folder opening/closing detection module 180, the control module 110 detects the output of the folder opening/closing detection signals in step 303 and reads the folder opening/closing detection signals output from the folder opening/closing detection module 180.
At this time, if the sensor (not shown) included in the body housing of the wireless terminal, which makes contact with the first folder housing 200-1 of the wireless terminal, detects the magnet included in the first folder housing 200-1, and if the sensor (not shown) disposed in the body housing of the wireless terminal, which makes contact with the second folder housing 200-2, detects the magnet (not shown) disposed in the second folder housing 200-2, the folder opening/closing detection module 180 recognizes this and generates the first folder opening/closing detection signal in step 304. In addition, the control module 110 reads the first folder opening/closing detection signal from the folder opening/closing detection module 180. If the first folder opening/closing detection signal is generated as described above, the control module 110 activates the first display module 161, the numeral keys of the first key input module 171, and the external keys of the second key input module 172 in step 305. In addition, the control module 110 deactivates the second display module 162, the inner keys of the first key input module 171, and the inner keys of the second key input module 172 in step 305. FIG. 2a shows a state in which the first folder housing 200-1 and the second folder housing 200-2 of the wireless terminal are closed.
However, if the sensor (not shown) included in the body housing of the wireless terminal, which makes contact with the first folder housing 200-1, does not detect the magnet (not shown) disposed in the first folder housing 200-1, and if the sensor (not shown) disposed in the body housing of the wireless terminal, which makes contact with the second folder housing 200-2, detects the magnet disposed in the second folder housing 200-2, the folder opening/closing detection module 180 detects this and generates the second folder opening/closing signal in step 306. In addition, the control module 110 reads the second folder opening/closing detection signal from the folder opening/closing detection module 180. If the second folder opening/closing detection signal is generated as described above, the control module 110 activates the first display module 161, the first screen 162-1 of the second display module, the inner keys of the first key input module 171, and the external keys of the second key input module 172 in step 307. In addition, the control module 110 deactivates the second display screen 162-2 of the second display module, the external keys of the first key input module 171, and the inner keys of the second key input module 172 in step 307. FIG. 2B shows a state in which the first folder housing 200-1 is opened and the second folder housing 200-2 is closed.
In addition, if the sensor (not shown) included in the body housing of the wireless terminal, which makes contact with the first folder housing 200-1, detects the magnet (not shown) included in the first folder housing 200-1, and if the sensor (not shown) included in the body housing of the wireless terminal, which makes contact with the second folder housing 200-2, does not detect the magnet included in the second folder housing 200-2, the folder opening/closing detection module 180 detects this and generates the third folder opening/closing signal in step 308. In addition, the control module 110 reads the third folder opening/closing detection signal from the folder opening/closing detection module 180. If the third folder opening/closing detection signal is generated as described above, the control module 110 activates the second screen 162-2 of the second display module 162, the external keys of the first key input module 171, and the inner keys of the second key input module 172 in step 309. In addition, the control module 110 deactivates the first display module 161, the first display screen 162-2 of the second display module 162, the inner keys of the first key input module 171, and the external keys of the second key input module 172 in step 309. FIG. 2C shows a state in which the first folder housing 200-1 is closed and the second folder housing 200-2 is opened.
Finally, if the sensor (not shown) disposed in the body housing of the wireless terminal, which makes contact with the first folder housing 200-1, does not detect the magnet (not shown) disposed in the first folder housing 200-1, and if the sensor (not shown) disposed in the body housing of the wireless terminal, which makes contact with the second folder housing 200-2, does not detect the magnet disposed in the second folder housing 200-2, the folder opening/closing detection module 180 detects this and generates the fourth folder opening/closing signal in step 310. In addition, the control module 110 reads the fourth folder opening/closing detection signal from the folder opening/closing detection module 180. If the fourth folder opening/closing detection signal is generated as described above, the control module 110 activates the second display module 162, the inner keys of the first key input module 171, and the inner keys of the second key input module 172 in step 311. In addition, the control module 110 deactivates the first display module 161, the external keys of the first key input module 171, and the external keys of the second key input module 172 in step 311. FIG. 2D shows a state in which the first folder housing 200-1 and the second folder housing 200-2 are closed.
FIG. 5 is a flowchart illustrating a method for controlling the rotary-type speakers in the wireless terminal according to an embodiment of the present invention. Hereinafter, the method for controlling the rotary-type speakers in the wireless terminal including the folder opening/closing detection module 180 shown in FIGS. 4A and 4B will be described with reference to FIG. 5. A rotary-type speaker according to an embodiment of the present invention includes a first rotary-type speaker and a second rotary-type speaker mounted inside the first folder and the second folder, respectively. In addition, it is assumed that the first rotary-type speaker and the second rotary-type speaker are rotatably moved away from the first folder and the second folder, respectively, or rotatably close to the first folder and the second folder, respectively.
Referring to FIG. 5, in step 501, the control module 110 determines if a current mode is a display mode. Herein, the display mode denotes a mode in which the body housing of the wireless terminal makes contact with the folder housing, thereby displaying an image on the first display module 161 and the body housing of the wireless terminal pivots away from the folder housing, thereby displaying an image on the second display module 162. When an automatic display change mode is set up in the display mode described above, the control module 110 detects the set up of the automatic display change mode in step 502. Herein, the automatic display change mode denotes a mode in which the functions of the first and the second rotary-type speakers 118 and 119 are controlled according to a folder opening/closing detection signal of the folder opening/closing detection module 180. Accordingly, if the automatic display change mode is not set up, the control module 110 performs typical functions for the first rotary-type speaker 118 and the second rotary-type speaker 119 regardless of the output of the folder opening/closing detection module 180. However, if the automatic display change mode is set up, the control module 110 determines if a folder opening/closing detection signal is output from the folder opening/closing detection module 180. If the folder opening/closing detection signal is output from the folder opening/closing detection module 180, the control module 110 detects the folder opening/closing detection signal and reads the folder opening/closing detection signal output from the folder opening/closing detection module 180 in step 503.
Herein, if a sensor (not shown) included in the body housing of the wireless terminal (making contacts with the first folder housing 200-1 of the wireless terminal) detects a magnet (not shown) included in the first folder housing 200-1, and if a sensor (not shown) included in the body housing of the wireless terminal (making contacts with the second folder housing 200-2) detects a magnet (not shown) included in the second folder housing 200-2, the folder opening/closing detection module 180 recognizes the detection so as to generate the first folder opening/closing detection signal in step 504. In addition, the control module 110 reads the first opening/closing detection signal from the folder opening/closing detection module 180. If the first folder opening/closing detection signal is generated as described above, the control module 110 controls the first rotary-type speaker 118 and the second rotary-type speaker 119 to be deactivated in step 505. FIG. 4A illustrates the first folder housing 200-1 and the second folder housing 200-2 of the wireless terminal in the close state.
However, if the sensor (not shown) included in the body housing of the wireless terminal (making contacts with the first folder housing 200-1 of the wireless terminal) does not detect a magnet (not shown) included in the first folder housing 200-1, and if the sensor (not shown) included in the body housing of the wireless terminal (making contacts with the second folder housing 200-2) detects a magnet (not shown) included in the second folder housing 200-2, the folder opening/closing detection module 180 recognizes the detection so as to generate the second folder opening/closing detection signal in step 506. In addition, the control module 110 reads the second opening/closing detection signal from the folder opening/closing detection module 180. If the second folder opening/closing detection signal is generated as described above, the control module 110 controls the first rotary-type speaker 118 to be activated and the second rotary-type speaker 119 to be deactivated in step 507. Herein, the control module 110 detects the rotation state of the first rotary-type speaker 118 and may control the first rotary-type speaker to be activated only when the first rotary-type speaker 118 is rotatably moved away from the first folder housing 200-1. In addition, the second speaker of the second voice inputting/outputting module 116 may be activated together with the first rotary-type speaker. FIG. 4B illustrates the first folder housing 200-1 in the open state and the second folder housing 200-2 in the close state.
In addition, if the sensor (not shown) included in the body housing of the wireless terminal (making contacts with the first folder housing 200-1 of the wireless terminal) detects the magnet (not shown) included in the first folder housing 200-1, and if the sensor (not shown) included in the body housing of the wireless terminal (making contacts with the second folder housing 200-2) does not detect a magnet (not shown) included in the second folder housing 200-2, the folder opening/closing detection module 180 recognizes the detection so as to generate the third folder opening/closing detection signal in step 508. In addition, the control module 110 reads the third opening/closing detection signal from the folder opening/closing detection module 180. If the third folder opening/closing detection signal is generated as described above, the control module 110 controls the first rotary-type speaker 118 to be deactivated and the second rotary-type speaker 119 to be activated in step 509. Herein, the control module 110 detects the rotation state of the second rotary-type speaker 119 and can control the second rotary-type speaker to be activated only when the second rotary-type speaker 119 is rotatably moved away from the second folder housing 200-2. In addition, the first speaker of the first voice inputting/outputting module 115 may be activated together with the second rotary-type speaker 119. FIG. 4C illustrates the first folder housing 200-1 in the close state and the second folder housing 200-2 in the open state.
Finally, if the sensor (not shown) included in the body housing of the wireless terminal (making contacts with the first folder housing 200-1 of the wireless terminal) does not detect the magnet (not shown) included in the first folder housing 200-1, and if the sensor (not shown) included in the body housing of the wireless terminal (making contacts with the second folder housing 200-2) does not detect a magnet (not shown) included in the second folder housing 200-2, the folder opening/closing detection module 180 recognizes the detection failure so as to generate the fourth folder opening/closing detection signal in step 510. The control module 110 reads the fourth opening/closing detection signal from the folder opening/closing detection module 180. If the fourth folder opening/closing detection signal is generated as described above, the control module 110 controls the first rotary-type speaker 118 and the second rotary-type speaker 119 to be activated in step 511. Herein, the control module 110 detects the rotation states of the first rotary-type speaker 118 and the second rotary-type speaker 119 and may control the first rotary-type speaker and the second rotary-type speaker to be activated only when the first rotary-type speaker 118 and the second rotary-type speaker 119 are rotatably moved away from the first folder housing 200-1 and the second folder housing 200-2, respectively. In addition, the first speaker of the first voice inputting/outputting module 115 and the second speaker of the second voice inputting/outputting module 116 may be activated together with the first rotary-type speaker 118 and the second rotary-type speaker 119. FIG. 4D illustrates the first folder housing 200-1 and the second folder housing 200-2 in the open state.
FIG. 10 is a flowchart showing a method for controlling a function of the voice inputting/outputting module in the wireless terminal according to an embodiment of the present invention. Specifically, a method for controlling a function of the voice inputting/outputting module 117 in the wireless terminal including the position detection module 190 shown in FIGS. 6A to 9B will be described with reference to FIG. 10. According to an embodiment of the present invention, it is assumed that the second voice inputting/outputting module 116 is mounted on the first hinge 210-1 coupling the first folder housing with the body housing of the wireless terminal, and the first voice inputting/outputting module 115 is mounted on the second hinge 210-2 coupling the second folder housing with the body housing of the wireless terminal.
Referring to FIG. 10, the control module 110 determines whether a current mode is a communication mode in step 801. If the current mode is the communication mode, the control module 110 determines whether or not the position detection module 190 outputs position detection signals. If the position detection module 190 outputs the position detection signals, the control module 110 detects the output of the position detection signals in step 802 and reads the position detection signals output from the position detection module 190.
At this time, if the wireless terminal is in an upright position, the position detection module 190 detects this and generates the first position detection signals in step 803. After that, the control module 110 reads a first position detection signal from the position detection module 190. When the first position detection signal is generated as described above, the control module 110 activates the first speaker of the first voice inputting/outputting module 115 mounted on the second hinge 210-1 and the second microphone of the second voice inputting/outputting module 116 mounted on the first hinge 210-1 in step 804. When the first position detection signal is generated as described above, the control module 110 deactivates the first microphone of the first voice inputting/outputting module 115 and the second speaker of the second voice inputting/outputting module 116. FIGS. 6A, 7A, 8A, and 9A show the wireless terminal in an upright position in each state of the first to the fourth folder opening/closing states.
The control module 110 not only outputs a voice signal, which is transmitted from the audio processing module 125, through the first speaker of the first voice inputting/outputting module 115, but also performs voice communication in step 807 while receiving a voice signal through the second microphone of the second voice inputting/outputting module 116. If the communication ends, the control module 110 detects the end of the communication and terminates the communication mode in step 808.
In addition, if the wireless terminal has been rotated 180°, the position detection module 190 detects this in step 805 and generates the second position detection signal. The control module 110 reads the second position detection signal from the position detection module 190. When the second position detection signal is detected as described above, the control module 110 activates the first microphone of the first voice inputting/outputting module 115 mounted on the second hinge 210-2 and the second speaker of the second voice inputting/outputting module 116 mounted on the first hinge 210-1 in step 806, and deactivates the first speaker of the first voice inputting/outputting module 115 and the second microphone of the second voice inputting/outputting module 116. FIGS. 6B, 7B, 8B, and 9B show the wireless terminal rotated 180° in each state of the first to the fourth folder opening/closing states.
The control module 110 not only outputs a voice signal, which is transmitted from the audio processing module 125, through the second speaker of the second voice inputting/outputting module 116, but also performs voice communication in step 807 while receiving a voice signal through the first microphone of the first voice inputting/outputting module 116. If the communication ends, the control module 110 detects the end of the communication and terminates the communication mode in step 808.
As described above, according to the present invention, the functions of the wireless terminal are controlled according to the opening/closing states of the folder housings and the positions of the folder housings, so that it is convenient for a user to employ a display module, a key input module, and a rotary-type speaker which have functions automatically controlled according to the opening/closing states of the folder housings. In addition, it is convenient for the user to employ a voice inputting/outputting module having functions automatically controlled according to the positions of the wireless terminal.
While the invention has been shown and described with reference to certain embodiments thereof, it should be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
