And a microphone 180 for inputting a user voice and various sound signals.

On the keypad 110, keys for inputting numbers, symbols, characters, and the like, and keys for selecting various menus and executing various functions are arranged. When a specific key is pressed by the user, the keypad 110 generates a key signal for inputting numbers, symbols, and characters, or a key signal for instructing execution of a call service, and transmits it to the controller 140.

The memory 120 includes predetermined menu items provided to the user, for example, a phone book, a mobile phone setting, a schedule management, a convenient function, a fun function, a screen setting, a volume ringtone, and a submenu associated with the menu items. Save menu items.

The memory 120 stores various additional information, a driving program for providing a call and various additional services, and also uses the rotation data sensed by the position sensing unit 130 according to the present invention as a parameter. Stores an execution program used when calculating the rotation direction of the.

The position detecting unit 130 is configured in a form of being embedded in the mobile communication terminal 100, and serves to detect and transmit location data that is changed in association with the movement of the mobile communication terminal 100 to the control unit 140. As shown in FIG. 2, the sensor unit 131 and the A / D converter 132 are included.

The sensor unit 131 detects a position signal of the mobile communication terminal 100 having a predetermined direction and angle and changes according to movement, and provides the A / D conversion unit. More specifically, the geomagnetic sensor and speed It is composed of either sensor or gyro sensor.

At this time, the geomagnetic sensor is able to obtain the absolute orientation by using the principle of the magnetic needle to detect the direction of the magnetic force generated by the earth itself, and in this case, by detecting the magnetic field change generated in conjunction with the movement of the mobile communication terminal, the corresponding mobile communication terminal Serves to detect the position signal.
