MOBILE PHONE AND ITS EXTERNAL DEVICE CONNECTING METHOD, COMMUNICATION TERMINAL SYSTEM AND ITS USER IDENTIFICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a mobile phone usable for voice input/output means (microphone and speaker) for a communication terminal system or the like. SOLUTION: The mobile phone is characterized in that it includes; a USB interface section 37 connected to a personal computer (PC) via a USB cable 4 to transmit/receive data and detect that the USB cable 4 is connected; and a changeover means that switches a connection destination of the microphone 33 and the speaker 35 to a wireless communication section 32 or the USB interface section 37. When it is detected that the USB cable 4 is connected to the PC, a CPU 31 switches the connection destination of the microphone 33 and the speaker 35 to the USB interface section 37.
