Abstract
본 발명은 스테레오 신호에 대해 좌, 우측 2개의 스피커를 이용하여 3차원 이미지의 소리를 재현함에 있어 소리의 공간감을 확대하므로써 음장감과 아울러 저역음을 강조하는 생동감있는 사운드의 재현과 좌우 스피커의 센터측에 위치하는 음성 대역 및 중역대의 신호를 그대로 유지하는 균형잡힌 사운드를 재현시키는 한편 음원에 따른 특정대역의 보강을 고려한 서라운드 ㄷ스템에 관한 것이다.The present invention is to reproduce the sound of the three-dimensional image by using two left and right speakers for the stereo signal by reproducing the spatial sense of the sound, and to reproduce the lively sound that emphasizes the low frequency and the sound field sense and the center side of the left and right speakers The present invention relates to a surround sound system that considers reinforcement of a specific band according to a sound source while reproducing a balanced sound that maintains a signal of a voice band and a midrange located at the same position.
공간감을 확대하기 위한 기존 기술은 원 스테레오의 좌측과 우측의 음을 L+R 그리고 L-R의 신호 처리 및 주파수적인 보상을 거쳐 최종 매트릭스에에서 재배치함으로서 다수의 입체감은 형성할 수 있으나 L-R 신호의 주파수 및 위상특성이 좌측과 우측에 부가되어지면서 음의 좌우 균형이 깨어짐에 따라 음균형 손실 및 원음 손실의 영향이 크고 특히 L+R신호의 부가로 인해 오히려 스프트에 따라서는 스테레오감을 없애버리는 역효과 및 음의 명료성이 떨어지는 역현상이 일어나는 것이었다.Existing techniques to increase the sense of spatiality can be achieved by relocating the left and right notes of the original stereo to the final matrix through L + R and LR signal processing and frequency compensation. As the phase characteristic is added to the left and the right, the balance of the left and right of the sound is broken, so the effects of the balance loss and the original sound loss are large, and in particular, the addition of the L + R signal removes the stereo effect depending on the shift. The inverse of the intelligibility of the phenomenon was occurring.
본 발명은 좌, 우측 각각의 신호원으로부터 스테레오 이미지를 주파수적 측면에서의 추출을 위한 각 신호 채널측의 공간성조성부 및 좌우 각채널의 원음의 보강 및 유지를 위한 대역보상부 그리고 각채널의 매트릭스 수단, 최종단에서 특정 대역의 보강을 위한 대역보상부를 구성하므로써 상기된 문제점을 해결한 것이다.The present invention provides a spatial composition part on each signal channel side for extracting a stereo image from the left and right signal sources, and a band compensator for reinforcing and maintaining the original sound of each of the left and right channels, and matrix means of each channel. The above problem is solved by configuring a band compensator for reinforcing a specific band in the final stage.
