Abstract

본 발명은 음극선관에 관한 것으로, 종래에는 인바 새도우마스크 적용시 새도우마스크가 진동됨으로써, 음극선관 새도우마스크에 하울링(howling)현상이 발생되어 음극선관의 화질 품위를 손상시키는 문제점이 있었는 바, 새도우마스크(30)를 지지하는 프레임(31)의 장변과 단변 내측변 일정부위에 상기 새도우마스크(30)의 스커트면과 면접촉되는 적어도 1개 이상의 진동흡수부재(32)를 설치하여 구성한 것을 특징으로 하는 본 발명에 의한 음극선관을 제공하며, TV의 동작시 스피커의 진동에 의해 새도우마스크가 진동할 때 이 진동흡수부재(32)와 마스크(30)의 스커트면이 면접촉되어 있기 때문에 외부 요인에 의한 진동을 빠른 시간 내에 흡수하게 되어 간단한 구성으로 음극선관의 제조단가의 상승을 배제하고, 플랫화를 유지하면서 화질에 막대한 영향을 주었던 하울링 현상을 방지하도록 한 것이다.The present invention relates to a cathode ray tube, and in the related art, a shadow mask is vibrated when an inva shadow mask is applied, and a howling phenomenon occurs in the cathode ray tube shadow mask, thereby degrading the quality of the cathode ray tube. At least one vibration absorbing member (32) in surface contact with the skirt surface of the shadow mask (30) on the long side and short side inner side of the frame (31) for supporting the (30) The cathode ray tube according to the present invention is provided, and when the shadow mask vibrates due to the vibration of the speaker during operation of the TV, the surface of the skirt of the vibration absorbing member 32 and the mask 30 is in contact with each other due to external factors. Absorption of vibration in a short time, simple configuration eliminates the increase in manufacturing cost of cathode ray tube, while maintaining a flattening effect on image quality It would have had to prevent the howling phenomenon.
