또 상기 측벽(112)에는 이웃하는 타 흡음체의 내부에 구비된 측흡음판(104)을 통한 흡음효과를 얻을 수 있도록 통과 관통홀(106)이 형성되고, 상기 흡음체 전방의 각 모서리 내측에는 음파를 유입하는 유입관통홀(107)이 형성되며, In addition, the side wall 112 has a through hole 106 formed therein so as to obtain a sound absorbing effect through the side sound absorbing plate 104 provided inside the other sound absorbing body, and the sound wave inside each corner in front of the sound absorbing body. An inflow through-hole 107 is formed to inflow,

또 상기 후방흡음판(103)의 중앙에는 측벽의 폭보다 상대적으로 짧은 길이지지봉(108)이 장착되어 상기 진동판을 구성하는 중앙판(121)이 지지봉(108)의 끝단에 함몰되게 고정됨으로써, 상대적으로 공기층(111)의 부피를 확장시켜 용수철진동 현상을 증폭시켜 음파를 소멸시키고, 또한 상기 후방 및 측흡음판(103,104)은 다공부를 통해 음파를 흡음하는 스폰지 또는 유리섬유나 암면 등으로 구성되어 있다.In addition, the center of the rear sound absorbing plate 103 is relatively shorter than the width of the side wall length of the support rod 108 is mounted so that the central plate 121 constituting the diaphragm is fixed to the end of the support rod 108 to be relatively, The volume of the air layer 111 is expanded to amplify the spring vibration phenomenon to extinguish the sound waves, and the rear and side sound absorbing plates 103 and 104 are made of a sponge or glass fiber or rock wool that absorbs sound waves through the porous part.

상기와 같은 종래기술은 먼저 진동판(102)으로 유입되는 음파가 굴곡격판(221)을 따라 소용돌이 현상을 일으키게 함으로써 흡음면적을 증가시켜 흡음효과를 얻을 수 있으며 유입되는 음파가 굴곡격판을 통해 미세하게 떨림에 따라 공기층에서 용수철 진동현상이 일어나게 됨으로써 음파의 에너지를 소모시켜 흡음되는 기능이 발휘되는 구조로 이루어져 있다.In the prior art as described above, the sound wave introduced into the diaphragm 102 first causes a vortex phenomenon along the curved plate 221 to increase the sound absorbing area to obtain a sound absorbing effect, and the incoming sound wave shakes finely through the curved plate. As a result of the spring vibration phenomenon in the air layer is made of a structure that consumes the energy of the sound wave to absorb the sound.

상기와 같은 종래기술은 소리에너지를 흡음하는 흡음부가 스폰지나 유리섬유 또는 암면 등이 대부분 불투명체로 구성되어 흡음체를 경계로 시야를 방해하여 매우 답답하게 느껴져 생활이 상당히 불편하였고, 또 상기 종래기술은 상기 공기층의 면적이 안쪽으로 갈수록 점점 작아지는 구조로 되어 있어 내부로 유입되는 소리에너지 또한 적어져 흡음 및 방음 효과가 다소 떨어지는 문제가 있다. In the prior art as described above, the sound-absorbing portion that absorbs sound energy is composed of most non-transparent materials such as sponge, glass fiber, or rock wool, which obstructs the view around the sound absorbing body, making it very frustrating. As the area of the air layer becomes smaller toward the inside, there is a problem that the sound energy introduced into the interior also decreases, so that the sound absorbing and soundproofing effects are somewhat reduced.

또한 일반적으로 흡음이라 함은 소리에너지를 흡수하여 소멸시키는 것으로, 이에 사용되는 흡음판은 그 소재와 방법에 따라 매우 다양한 종류는 있으나 전· 후면의 시야가 잘 보이는 투명 흡음판은 전무한 실정이며, 도로방음용으로 사용되고 있는 투명판은 음파를 반사하며 차단하는 방음효과만 있어 방음/차음판으로만 설치를 하고 있는 실정이고, 종래의 투명 흡음판으로는 합성수지 투명판재에 미세한 구멍을 타공하여 흡음판으로 사용하는 방법도 있으나 이 역시 흡음 효과가 약해 흡음판이라고 할 수 없으며 가격이 비싸 특수한 곳에만 사용하고 있는 실정이다.In general, sound absorption means to absorb and dissipate sound energy, and there are various types of sound absorbing plates depending on the material and method, but there are no transparent sound absorbing plates having good visibility of the front and rear sides. The transparent plate used in the present invention has only a soundproofing / soundproofing plate that reflects and blocks sound waves, and the conventional transparent sound absorbing plate is also used as a sound absorbing plate by drilling a fine hole in a transparent resin sheet. However, this also has a weak sound absorbing effect is not a sound absorbing plate is expensive and the situation is used only in special places.

그리고 도로용 투명흡음판으로는 투명판의 틀 내부 테두리에 일정한 넓이의 흡음재를 부착하여 전방에서 발생된 충격음파가 투명판에 부딪힌 후 틀 내부 테두리에 부착된 흡음재에서 일부만 흡수되고 나머지 음파는 반사하는 투명 흡음판이 사용되고 있으나 이 또한 흡음효과는 매우 적다 할 것이다.      In addition, a transparent sound absorbing plate for the road is attached to a sound absorbing material having a certain width on the inner rim of the transparent plate so that the impact sound waves generated from the front hit the transparent plate, and only a part of the sound absorbing material attached to the inner rim of the frame is absorbed. A sound absorbing plate is used, but this also has a very low sound absorbing effect.

따라서 흡음효과를 높일 방법으로는 측면의 흡음재 부착 면적넓이를 넓힐수록 흡음효과는 높아지나 투명흡음판으로서의 실용가치가 없고, 최소의 넓이로 흡음효과를 높이는 방법은 아직 알려지지 않아 많은 연구 개발을 하고 있는 실정이다.       Therefore, as a method of enhancing the sound absorption effect, the sound absorbing effect is increased as the area of the side of the sound absorbing material is increased, but there is no practical value as a transparent sound absorbing plate, and the method of increasing the sound absorbing effect to the minimum area is not known yet. to be.

이에 본 발명은 상기와 같은 문제를 해결하기 위해 안출된 것으로, 합성수지의 아크릴판과 같은 투명체로 된 흡음플레이트와 방음플레이트를 흡음프레임을 매개로 일정간격 이격시켜 흡음공간부를 형성하고 상기 흡음공간부로 소리에너지를 유입시켜 흡음 및 방음이 이루어지도록 하는 동시에 흡음/방음체 전·후면이 잘 보이도록 시야를 확보할 수 있도록 된 투명한 흡음/방음체를 제공하는데 그 목적이 있다. Accordingly, the present invention has been made to solve the above problems, the sound-absorbing plate and the sound-absorbing plate made of a transparent material such as acrylic plate of synthetic resin spaced at a predetermined interval through the sound-absorbing frame to form a sound-absorbing space portion and the sound into the sound-absorbing space portion It is an object of the present invention to provide a transparent sound absorbing / sound absorbing body which can secure energy so that the sound absorbing and soundproofing can be made by introducing energy, and the front and rear surfaces of the sound absorbing / soundproofing body can be easily seen.

상기와 같은 목적을 달성하기 위한 본 발명의 탄성력을 갖는 투명흡음 및 방음체는 투명한 아크릴 합성수지판으로 되되 거미집형상의 소리유입통로(11)와 장공형 소리유입통로(12) 및 원형 소리유입통로(13)가 구비된 흡음플레이트(14)와, 투명한 아크릴 합성수지판으로 되어 소리에너지를 차단/방음하는 방음플레이트(15)와, 상기 흡음플레이트(14)와 방음플레이트(15)를 일정간격으로 이격시겨 내부에 흡음공간부(16)가 형성되도록 설치된 사각프레임(17) 및 상기 사각프레임(17)의 각 벽의 내측에 구비되어 소리에너지를 흡수하여 소멸시킬 수 있도록 된 흡음재(18)로 구성된 것을 특징으로한다.Transparent sound-absorbing and sound-proofing body having an elastic force of the present invention for achieving the above object is made of a transparent acrylic synthetic resin plate but the cobweb-shaped sound inflow passage 11 and the long hole-shaped sound inflow passage 12 and the circular sound inflow passage ( 13) is provided with a sound-absorbing plate 14, a transparent acrylic synthetic resin plate to block the sound energy / sound insulation plate 15, and the sound-absorbing plate 14 and the sound-proof plate 15 at a predetermined interval It is composed of a rectangular frame 17 installed to form a sound absorbing space portion 16 inside the bran and a sound absorbing material 18 provided to the inside of each wall of the rectangular frame 17 to absorb and dissipate sound energy. To be characterized.

상기와 같이 본 발명에 따른 탄성력을 갖는 투명 흡음 및 방음체는 흡음부와 방음부를 합성수지의 아크릴판으로 된 투명체로 구성하여 흡음/방음체 전·후면이 잘 보일 수 있도록 함으로써 활용성을 극대화할 수 있는 효과가 있고, 또 흡음판에 소리에너지를 유입하는 통로를 거미집 형상으로 중심에서부터 외부로 향할수록 발산하는 형태를 이루면서 소리에너지 유입면적을 증가시켜 흡음효율을 높일 수 있으며, 또한 투명의 얇은 아크릴판으로 된 흡음판이 소리에너지를 통과시키면서 탄성적으로 진동을 일으킴으로써 일부 소리에너지가 진동에너지로 변환되어 흡음효율을 더욱 높여 주는 효과를 얻을 수 있다.As described above, the transparent sound absorbing and soundproofing body having elastic force according to the present invention can maximize the utility by making the sound absorbing and soundproofing parts transparent and made of acrylic plate of synthetic resin so that the sound absorbing / soundproofing body can be easily seen. The sound absorbing efficiency is increased, and sound absorption efficiency is increased by increasing the sound energy inflow area as the cobweb shape is diverted from the center to the outside. By absorbing the sound absorbing plate through the sound energy and elastically vibrating, some sound energy is converted into the vibration energy to obtain the effect of further improving the sound absorption efficiency.
