Abstract

본 발명은 TV의 MLR(Mass Loaded Reflex)스피커 시스템에 관한 것이다.The present invention relates to a mass loaded reflex (MLR) speaker system of a TV.

일반적으로 저음역 중강이나 저음재생 한계를 낮추기 위하여 베이스 리플렉스 스피커 시스템(Bass Reflex Speaker System)이 다수 사용되고 있다.In general, a bass reflex speaker system is used to lower the bass midrange or bass reproduction limit.

본 발명은 이 베이스 리플렉스 시스템을 이용한 것으로서 상협 하광의 캐비티(Cavity)와 그 양측면부에 도파관을 연통시켜서 된 스피커 박스를 TV 캐비넷의 CRT 후방공간에 설치하므로써, TV의 스피커 시스템으로서는 상당히 낮은 주파수 대역까지 저음을 재생할 수 있도록 한 것이다.The present invention utilizes this bass reflex system, and by installing a speaker box in which the cavity of the upper and lower light beams and the waveguides are connected to both sides thereof in the rear space of the CRT of the TV cabinet, the speaker system of the TV can reach a very low frequency band. The bass can be played back.
