Abstract

4 채널 돌비 사운드 시스템에 사용되는 중앙 채널 확성기 시스템이 제공된다. 제1확성기(18)는 엔클로저(10)이 전방에 설치되고, 제1확성기(18)보다 낮은 주파수 범위를 갖고 제1확성기(18)보다 큰 원뿔 크기를 각각 갖는 제2 및 제3확성기(12,14)는 제1확성기(18)의 수직 평면 후방에서 약 40도 각도로 제1확성기(18)의 각 측면상의 엔클로저(10) 전방에 설치된다. 이같은 배치로 근접하게 이격된 중앙 채널 확성기 시스템에서 방지하는 음의 파괴적 소멸이 최소화된다.A central channel loudspeaker system for use with a four channel Dolby sound system is provided. The first loudspeaker 18 includes the second and third loudspeakers 12 having an enclosure 10 installed in front and having a lower frequency range than the first loudspeakers 18 and a larger cone size than the first loudspeakers 18, respectively. 14 is installed in front of the enclosure 10 on each side of the first loudspeaker 18 at an angle of about 40 degrees behind the vertical plane of the first loudspeaker 18. This arrangement minimizes the destructive dissipation of sound that is prevented in closely spaced central channel loudspeaker systems.
