Abstract

본 발명은 영상표시기기에서 스피커에 의한 브라운관(CPT)의 화면 떨림 방지 구조에 관한 것으로서, 종래에는 스피커에서 발생된 진동이 고체 매체를 통해 직접CPT로 전달되기 때문에 심한 화면 떨림 현상이 발생하는 문제점과, 이로 인하여 사용자가 화면을 보고 작업할때 화면 떨림으로 인하여 눈이 쉽게 피로해 짐은 물론, 화상이 깨끗하지 못해 제품의 신뢰성이 저하된다.The present invention relates to a screen shake prevention structure of a cathode ray tube (CPT) by a speaker in a video display device. In the related art, since a vibration generated in a speaker is directly transmitted to a CPT through a solid medium, a severe screen shake phenomenon occurs. Due to this, when the user looks at the screen and works, the eyes are easily tired due to the shaking of the screen, and the image is not clear and the reliability of the product is deteriorated.

특히, 모니터의 경우 15인치 이상은 섀도우 마스크의 재질이 티브이(TV)보다 훨씬 강하게 진동을 하며, 내부신호 및 정지 화면인 동시에 풀 화이터 패턴을 사용하기 때문에 화면 떨림이 상당히 심하므로서, 상기 l5인치 이상에서는 CPT의 제작업체를 선별 적용하여야 하고, 일정치(0.5W × 2) 이상의 사운드(Sound)출력은 낼수 없는 문제점이 있었다.Particularly, in case of the monitor, the shadow mask material vibrates much stronger than the TV (TV), and because of the internal signal and the still image and the full-figure pattern, the screen shake is quite severe, and thus the l5 inch or more In the CPT manufacturers must be applied selectively, there was a problem that can not produce a sound output over a certain value (0.5W × 2).

따라서, 본 발명은 상기와 같은 문제점을 해결하기 의해 스피커가 체결되는 수단을 구비하고, 체결된 스피커에서 발생되는 진동이 CPT에 직접 전달되지 않도록 진동을 흡수하는 수단을 구비하므로서, 화면 떨림현상의 방지에 따른 높은 와트수(Wattage)의 재생에 의해 선명하고 깨끗한 화면을 제공하여 제품의 품질을 향상시킬 수 있는 영상표시기기에서 스피커에 의한 브라운관(CPT)의 화면 떨림 방지 구조이다.Therefore, the present invention is provided with a means for fastening the speaker by solving the above problems, and having a means for absorbing the vibration so that the vibration generated in the fastened speaker is not directly transmitted to the CPT, preventing the screen shake phenomenon This is a structure that prevents screen shake of CRT by speaker in video display device that can improve product quality by providing clear and clean screen by high wattage reproduction.
