Abstract

본 발명은 전화기의 벨신호를 가변시킬 수 있는 가변장치를 사용하여 복수의 전화기로부터 출력되는 벨신호음을 가변시켜 어느 전화기에서 출력되는 벨신호음인지를 금방 인식 가능하도록 하기 위한 전화기의 벨신호가변장치에 관한 것으로, 송신측의 전화통화신호에 의해 수신측의 벨신호발생회로(10)로부터의 전화벨신호에 따른 전화벨소리를 출력시키는 스피커(22)를 갖춘 전화기에서 상기 벨신호발생회로(10)로부터 출력되는 벨신호를 가변시키는 가변장치(12)를 포함하여 구성된 것이다.The present invention uses a variable device that can vary the bell signal of the telephone to change the ring tone to be output from a plurality of telephones to the bell signal variable device of the telephone to quickly recognize which ring tone to be output from which telephone In the present invention, a telephone having a speaker 22 for outputting a telephone ringing sound corresponding to a telephone ringing signal from a ringing signal generating circuit 10 on the receiving side by a telephone call signal on the transmitting side is outputted from the ringing signal generating circuit 10. It is configured to include a variable device 12 for varying the bell signal.
