Abstract
본 발명은 전화기 주변의 소음레벨에 따라 전화기의 벨음량을 자동으로 조절하여 출력하도록 하는 벨음량 자동조절방법에 관한 것으로, 종래에는 벨음량이 고정되어 있어 전화기 주변의 환경에 따라 벨신호가 소음으로 느껴진다거나 잘들리지 않게 되는 문제점이 있었다.The present invention relates to a method for automatically adjusting a bell sound volume of a telephone set according to a noise level around a telephone set, There is a problem that it is felt or is not audible.
본 발명은 상대방으로 부터의 착신호 도래시 후크스위치(10)와 통화회로(12)를 통해 마이크로프로세서(14)를 구동시키고, 상기 마이크로프로세서 (14)에서는 벨구동부(16)를 구동시켜 벨신호를 스피커(18)로 출력하도록 하는 전화기의 벨음량 자동조절방법에 있어서, 상기 통화회로(12)에는 전화기 주변의 소음을 감지하는 소음감지부(20)가 연결되고, 상기 벨구동부(16)와 스피커(18) 사이에 벨음량조절부(22)가 연결되어 상기 마이크로프로세서(14)는 소음감지부(20)를 통해 감지하는 소음레벨에 따라 벨음량조절부(22)를 제어하여 기존에 설정되어 있는 벨신호에 소음감지부(20)에서 감지한 소음레벨을 합산한 음량의 벨신호를 출력하도록 하는 발명임.The present invention drives the microprocessor 14 through the hook switch 10 and the communication circuit 12 when an incoming call arrives from the other party and the microprocessor 14 drives the bell driver 16, Wherein the noise sensing unit 20 is connected to the communication circuit 12 for sensing the noise of the surrounding area of the telephone, and the bell driving unit 16 and the bell driving unit 16 are connected to each other, The bell volume control unit 22 is connected between the speakers 18 so that the microprocessor 14 controls the bell volume control unit 22 according to the noise level detected by the noise detection unit 20, And outputs a bell signal of a volume obtained by adding the noise level detected by the noise sensing unit 20 to the bell signal.
