Abstract
본 발명은 전화기에 관한 것으로, 더욱 상세하게는 발신자를 인식하여 특정의 링신호를 출력하는 발신자 인식기능을 구비한 링신호출력장치에 관한 것이다. 이 링신호출력장치는, 상기 국선과 연결되어, 상기 국선을 통해 입력되는 특정의 착신신호의 전압 레벨을 조절하기 위한 레벨 시프트의; 상기 레벨 시프트의 출력단자와 연결되고, 상기 레벨 시프트를 통해 입력되는 전압 레벨이 조절된 착신신호를 원래의 신호로 복조하는 디코더와; 상기 디코더의 출력단자와 연결되고, 상기 디코더에서 복조되어 출력하는 신호에 설정된 음향신호를 선택, 출력하는 음향선택단자와; 상기 음향선택단자의 출력단자와 연결되고, 상기 출력되는 음향신호를 증폭하는 증폭기와; 상기 증폭기의 출력단자와 연결되고, 상기 증폭되어 출력되는 음향신호를 출력하는 스피커를 포함함을 특징으로 한다.The present invention relates to a telephone, and more particularly, to a ring signal output device having a caller recognition function for recognizing a caller and outputting a specific ring signal. The ring signal output device is connected to the trunk line, and has a level shift for adjusting a voltage level of a specific incoming signal inputted through the trunk line; A decoder connected to an output terminal of the level shift and demodulating an incoming signal whose voltage level inputted through the level shift is adjusted into an original signal; A sound selection terminal connected to an output terminal of the decoder and configured to select and output a sound signal set in a signal demodulated and output by the decoder; An amplifier connected to an output terminal of the sound selection terminal and amplifying the output sound signal; And a speaker connected to the output terminal of the amplifier and outputting the amplified and output sound signal.
