Abstract

본 발명은 오디오 재생 장치에 관한 것으로서, 기 자화된 자기 테이프에 기록된 자기적인 음성신호를 전기적은 음성신호로 재생하는 코일과, 상기 코일의 소정 방향으로 감겨진 코어를 구비하는 헤드부와, 상기 헤드부에서 재생된 음성신호를 증폭하는 등화증폭기와, 상기 증폭된 음성신호를 후단부에 안전화된 신호를 공급하는 버퍼와, 상기 버퍼에서 출력되는 음성신호를 인가받아 외부로 출력하는 출력부를 포함하는 오디오 재생 장치에 있어서, 상기 헤드부의 코어에 감겨진 코일의 방향과 반대 방향으로 감겨져 상기 음성신호 재생시 발생되는 잡음을 제거하는 더미코일이 더 포함됨을 특징으로 한다. 따라서, 기자화된 자기 테이프를 재생하는 오디오 재생 장치에서 헤드부의 코어에 감겨진 코일의 방향과 반대로 감겨진 더미코일을 실장함으로써, 음성신호 재생시 데크 구동부의 구동에 의해 발생되는 잡음을 제거한 음성신호를 획득할 수 있는 잇점이 있다.The present invention relates to an audio reproducing apparatus, comprising: a coil for reproducing a magnetic voice signal recorded on a magnetized magnetic tape as an electrical voice signal, a head having a core wound in a predetermined direction of the coil; An equalization amplifier for amplifying the voice signal reproduced by the head unit, a buffer for supplying a signal secured to the rear end of the amplified voice signal, and an output unit for receiving the voice signal output from the buffer and outputting the external signal to the outside; The audio reproducing apparatus, further comprising a dummy coil wound in a direction opposite to the direction of the coil wound around the core of the head to remove noise generated when the voice signal is reproduced. Therefore, in the audio reproducing apparatus for reproducing the magnetized tape, a dummy coil wound in a direction opposite to the direction of the coil wound around the core of the head portion is mounted, thereby eliminating the noise generated by driving the deck drive unit during the reproduction of the audio signal. There is an advantage that can be obtained.
