Abstract
본 발명은 음성 출력 모드 변환 장치에 관한 것으로, 방송 신호를 수신하는 안테나(10)와, 안테나(10)에서 수신된 방송 신호중 한 채널의 신호를 튜닝하여 출력하는 튜너(20)에서 튜닝되어 제공되는 신호중 4.72MHz 대역의 신호만을 필터링하여 출력하는 대역 통과 필터(band pass filter:30)와, 대역 통과 필터의 출력 신호중에서 55.1KHz주파수에 위치한 파일롯 신호를 검출하므로써 음성 신호의 형태를 판별하고 이에 따라 음성 신호의 출력 모드를 설정하여 출력하는 음성 다중 처리부(40)와 음성다중 처리부(40)에서 판별되는 음성 신호의 형태가 소정의 짧은 시간내에 수시로 변할 경우 음성신호 출력 모드를 모노 모드로 강제 자동 변환하기 위한 제어 신호를 음성 다중 처리부(40)로 출력하는 마이컴(50)과, 음성 다중 처리부(40)의 출력 신호를 음성 신호 처리하여 출력하는 음성 신호 처리부(60)와, 음성 신호 처리부(60)의 출력 신호를 사용자가 들을 수 있도록 처리하여 외부로 송출하는 스피커(70)를 포함하고 구성되어, 스테레오 또는 음성 다중 신호가 포함되는 방송 신호 수신시, 외부 영향에 의해 수신이 잘되지 않아 음성 출력 모드가 수시로 변하여 안정된 음성 출력 신호를 얻지 못할 경우 강제로 음성 신호 출력 모드를 모노 모드로 설정하므로써 안정된 음성 출력 신호를 얻을 수 있도록 한 것이다.The present invention relates to a voice output mode converting apparatus, which is provided by being tuned by an antenna (10) for receiving a broadcast signal and a tuner (20) for tuning and outputting a signal of one channel of the broadcast signal received from the antenna (10). A band pass filter (30) that filters and outputs only signals in the 4.72 MHz band among the signals, and a pilot signal located at a frequency of 55.1 KHz from the output signals of the band pass filter are detected to determine the shape of the voice signal and thereby Forced automatic conversion of the voice signal output mode to mono mode when the form of the voice signal determined by the voice multiprocessor 40 and the voice multiprocessor 40 that sets and outputs the signal output mode changes frequently within a predetermined short time The microcomputer 50 for outputting the control signal for the voice to the multi-processing unit 40 and the output signal of the voice multi-processing unit 40 to process the voice signal A voice signal processor 60 and a speaker 70 that processes the output signal of the voice signal processor 60 so that a user can listen and transmits it to the outside, and includes a stereo or voice multiple signal. When receiving a signal, if the voice output mode changes frequently from time to time due to external influences and a stable voice output signal cannot be obtained, the voice signal output mode is forcibly set to mono mode to obtain a stable voice output signal.
