Abstract

본 발명은 정선속도 재생기에 있어서 원형음을 재생할 때 그 재생속도를 제어하는 기술에 관한 것으로, 일반적인 정선속도 재생기에 있어서는 재생기의 조절하는 기능이 구비되어 있지 않아 상기와 같이 원형음을 보다 효과적으로 사용할 수 없는 결함이 있었는바, 본 발명은 이를 해결하기 위하여 메모리소자(2)에 기록된 음성데이타의 리드할 때, 그 리드신호(CS)의 주파수를 조정하는 수단으로 재생속도를 자유롭게 가변할 수 있게 한 것이다.The present invention relates to a technique for controlling the reproduction speed when playing a circular sound in a fixed speed player, the general fixed speed player is not equipped with a function of adjusting the player can be used more effectively as described above. In order to solve this problem, the present invention provides a means for adjusting the frequency of the read signal CS so as to freely change the playback speed when reading the audio data recorded in the memory device 2. will be.
