SPEAKER-RECEIVER-MIKE ALL-IN-ONE SYSTEM AND MOBILE COMMUNICATION TERMINAL BY USING IT AND SPEAKER-RECEIVER-MIKE MODE SWITCHING SCHEME

摘要

A speaker-receiver-microphone integrated apparatus, a mobile terminal using the same and a mode converting method of the mobile terminal are provided to improve the convenience and satisfaction of a user by including a stereo voice recording function and an external loud speaker when reproducing music and movie. A receiver terminal is connected to one side of resistance. A speaker terminal is connected with a coil formed around a vibration plate(300, 400). A microphone terminal is connected to the other side of the resistance. A speaker-receiver-microphone integrated apparatus selectively applies a speaker mode, a receiver mode, and a microphone mode by using the vibration plate. Voltage is applied to both ends of coil through the speaker terminal.
