Examples of events occurring in the mobile terminal include call signal reception, message reception, and key signal input. The alarm unit 153 may output a signal for notifying occurrence of an event in a form other than an audio signal or a video signal. For example, the signal may be output in the form of vibration. When a call signal is received or a message is received, the alarm unit 153 may output a vibration to inform this. Alternatively, when a key signal is input, the alarm unit 153 may output a vibration in response to the key signal input. Through the vibration output as described above, the user can recognize the occurrence of the event. Of course, the signal for notification of event occurrence may be output through the display unit 22 or the voice output module 152.

The memory 160 may store a program for processing and controlling the controller 24, and may provide a function for temporarily storing input / output data (for example, a phone book, a message, a still image, a video, etc.). It can also be done.

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), RAM Random Access Memory (RAM) Static Random Access Memory (SRAM), Read-Only Memory (ROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), Programmable Read-Only Memory (PROM) magnetic memory, It may include at least one type of storage medium of the optical disk. In addition, the mobile terminal 100 may operate a web storage that performs a storage function of the memory 150 on the Internet.

The controller 24 typically controls the overall operation of the mobile terminal. For example, perform related control and processing for voice calls, data communications, video calls, and the like. In addition, the controller 24 may include a multimedia module 181 for multimedia reproduction. The multimedia module 181 may be implemented in the controller 24 or may be implemented separately from the controller 24.

The power supply unit 190 receives an external power source and an internal power source under the control of the controller 24 to supply power for operation of each component.
