SOUND ABSORBING TYPE SOUNDPROOF PANEL
Disclosed in the present invention is a sound absorbing-type soundproof panel, which comprises: a front surface plate at which a plurality of sound absorbing holes are punched for introducing sound waves and air entrance; a rear surface plate which is arranged at the rear side of the front surface plate at a predetermined interval; a side surface plate which is provided at both side surfaces of the front surface plate and the rear surface plate; a first diffraction plate which is built between the front surface plate and the rear surface plate, and in which a plurality of first grates are vertically arranged to be in parallel with each other at a predetermined interval while forming a first slit having a shape with the width becoming narrower from the front side toward the rear side to restrict the passing of the noise introduced by means of the noise absorption holes; a second diffraction plate which is built between the rear surface plate and the first diffraction plate, and in which a plurality of second grates are vertically arranged to be in parallel with each other at a predetermined interval while forming a second slit having a shape with the width becoming narrower from the front side toward the rear side to restrict the passing of the noise introduced by means of the first slit; and an air space formed between the second diffraction plate and the rear surface plate at the rear side. Therefore, the overall thickness may be minimized.
본 발명에서는 음파 유입 및 공기 출입을 위한 다수의 흡음구멍이 뚫린 전면판, 상기 전면판의 뒤쪽에 일정한 간격을 두고 배치된 후면판, 상기 전면판과 상기 후면판의 양쪽 측면에 구비된 측면판, 상기 전면판과 상기 후면판 사이에 내장되고, 상기 흡음구멍을 통해 유입되는 소음을 제한하여 통과시키기 위해 앞쪽에서 뒤쪽으로 갈수록 점차 폭이 좁아지는 모양의 제1슬릿을 형성하는 다수의 제1그레이트가 상하로 평행하게 일정한 간격을 두고 배열된 제1회절판, 상기 후면판과 상기 제1회절판 사이에 내장되고, 상기 제1슬릿을 통해 유입되는 소음을 제한하여 통과시키기 위해 앞쪽에서 뒤쪽으로 갈수록 점차 폭이 좁아지는 모양의 제2슬릿을 형성하는 다수의 제2그레이트가 상하로 평행하게 일정한 간격을 두고 배열된 제2회절판 및 상기 제2회절판과 배후의 상기 후면판과의 사이에 형성된 에어 스페이스를 포함하는 흡음형 방음판을 개시한다.
