Abstract

전화기의 착신경보음으로 멜로디나 벨중 어느 하나를 사용자가 선택할수 있도록 제어하는 회로에 관한 것이다.The present invention relates to a circuit for controlling a user's choice of a melody or a bell by a telephone ringing tone.

벨로써 착신 경보 가능함은 물론이고, 다양한 멜로디를 내장하여 사용자의 선택에 의해 벨 대신 멜로디 음을 착신 경보음으로 이용할수 있으며, 전원공급상의 문제로 인한 착신 멜로디 기능 수행 불가능 상태일시에는 벨로써 착신 경보하도록 자동 전환 가능하다.As well as ringing incoming alarm, various built-in melody can be used as a ringing alarm sound instead of bell by user's choice.When the incoming melody function cannot be performed due to power supply problem, incoming ringing alarm as bell Automatic switching is possible.
