Abstract

본 발명은 카 오디오에 관한 것으로 카 오디오에 인가되는 전압을 절환하여 카세트 테이프의 출력모드와 라디오출력모드를 수행하는 카 오디오에 있어서, 데크의 소정위치에 장착되어 탑승자가 카세트 테이프를 투입시켰는지 여부를 감지하는 테이프투입검출부와, 상기 테이프투입검출부의 출력단에 접촉되어 카세트 테이프의 투입여부에 따라 카 오디오의 출력모드를 변환하는 마이컴과, 상기 마이컴의 출력신호에 따라 카 오디오를 동작시키는 전압을 절환하여 카 오디오의 출력모드를 가변시키는 전압절환부를 구비하여 카 오디오의 데크에서 라디오와 카세트 테이프를 출력시키게 하는 전압 절환스위치를 제거하여 카 오디오의 불량률 저하 및 카 오디오의 제조원가를 경감하는 것이다.The present invention relates to car audio, and in car audio performing a cassette tape output mode and a radio output mode by switching a voltage applied to car audio, whether a passenger inserts a cassette tape in a predetermined position of a deck. A tape input detection unit for detecting a signal, a microcomputer that contacts the output terminal of the tape input detection unit, converts a car audio output mode according to whether a cassette tape is inserted, and switches a voltage for operating car audio according to the output signal of the microcomputer Thus, a voltage switching unit for varying the output mode of the car audio is provided to remove the voltage switching switch for outputting the radio and the cassette tape from the deck of the car audio, thereby reducing the defect rate of the car audio and the manufacturing cost of the car audio.
