Abstract

본 발명은 스피커 시스템을 구성하는 인클로저(enclosure)내부에 설치된 덕트를 이동시킬 수 있는 덕트 이동수단을 설치한 스피커 시스템(speaker system)의 덕트구조에 관한 것으로, 인클로저의 내측에 설치된 덕트를 이동시켜 덕트의 전체 길이를 가변시킴으로써 음의 미세조정이 가능한 스피커 시스템의 덕트 구조를 제공함에 그 목적이 있는 것으로, 그 구조는 인클로저와, 적어도 하나의 스피커유니트와, 주파수대역을 분할하는 디바이딩네트워크로 이루어지는 스피커 시스템에 있어서, 제1덕트(16)의 내주연에 삽입되어 있고, 덕트이동수단(20)은 상기 제2덕트(18)를 감싸면서 소정방향으로 이동시키도록 된 것이다.The present invention relates to a duct structure of a speaker system provided with a duct moving means capable of moving a duct installed in an enclosure constituting a speaker system. The object of the present invention is to provide a duct structure of a speaker system in which sound fine tuning is possible by varying the overall length of the speaker, the structure comprising an enclosure, at least one speaker unit, and a dividing network dividing a frequency band. In the system, it is inserted in the inner circumference of the first duct 16, the duct movement means 20 is to move in a predetermined direction surrounding the second duct (18).
