일반적으로 흡음이라 함은 물체가 소리를 흡수하는 일을 말하는 것으로서, 유리섬유 또는 암면 등의 다공성(多孔性)을 이용하여 흡음을 하거나, 판 또는 천등의 막진동(膜振動)을 이용하여 흡음을 하는 경우가 널리 알려져 있는 실정이다.In general, sound absorption refers to absorption of sound by an object. Sound absorption is made by using porous materials such as glass fiber or rock wool, or sound absorption is performed by using membrane vibration such as plate or cloth. If the situation is widely known.
이에 본 고안은 본 출원인이 기출원한 대한민국 실용신안등록출원 제 2002 - 9606호의 "흡음체"(이하, "종래고안" 이라 칭함)를 개량한 것이다.The present invention is an improvement of the "absorber" (hereinafter, referred to as "priority draft") of the Republic of Korea Utility Model Registration Application No. 2002-9606 filed by the present applicant.
이에 도 6은 본 출원인이 기 출원한 흡음체의 단면도로서, 먼저 그 구성을 설명하면 다음과 같다.6 is a cross-sectional view of the sound absorber previously filed by the present applicant. First, the configuration thereof will be described.
전후방이 개방되어 있고 측벽을 가지며 내부에 공기층(11)이 구비된 틀체(1)와, 상기 틀체(1)의 공기층(11)에 하나 이상으로 장착되어 있으며 음파의 소용돌이 현상을 일으키게 하여 음파를 흡음하고 음파를 공기층으로 통과시켜 음파를 소진하는 진동판(2)과, 상기 틀체(1)의 후방에 장착되어 공기층을 통과한 음파를 흡음하는 후방 흡음판(3)으로 구성된다.One or more frames (1) having an air layer (11) in the front and back and having an open side wall, and an air layer (11) therein, are mounted to at least one of the air layers (11) of the frame (1).

또한 흡음부를 구성하는 굴곡격판이 음파를 통해 미세하게 떨리게 하여(막진동 현상이 일어나게 함) 공기층에서 용수철진동 현상이 일어나게 함으로서, 음파(소리)의 에너지를 소모시킴으로서 흡음의 효과를 얻을 수 있는 것이다.In addition, the bending plate constituting the sound absorbing portion is shaken finely through the sound waves (membrane vibration phenomenon occurs) to cause the spring vibration phenomenon in the air layer, it is possible to obtain the effect of sound absorption by consuming energy of sound waves (sound).
이에, 본 고안은 상기한 흡음체에 있어서 흡음 효과를 좀더 증폭시킬 수 있도록 개량한 것으로서, 흡음체를 구성하는 공기층의 내측 둘레에 다공부를 가지는측 흡음판을 장착함으로서 다공성을 통한 흡음 효과를 극대화시킬 수 있는 흡음체를 제공함을 목적으로 한다.Thus, the present invention is to improve the sound absorbing effect in the above-mentioned sound absorbing body to further amplify, by maximizing the sound absorbing effect through the porous by mounting a side sound absorbing plate having a porous portion in the inner circumference of the air layer constituting the sound absorbing body It is an object of the present invention to provide a sound absorbing material.
또한 전방에 형성된 굴곡격판의 주위에는 공간부의 둘레에 장착된 흡음체로 음파가 유입되는 다수의 관통홀을 형성시켜 다공성을 통한 흡음 효과를 좀더 증폭시킬 수 있는 목적도 있다.In addition, there is also an object to further amplify the sound absorbing effect through the porosity by forming a plurality of through-holes through which sound waves are introduced into the sound absorbing body mounted around the curved portion formed around the curved plate formed in the front.
또 흡음체를 구성하는 측벽에는 하나 이상의 관통홀을 형성시켜 이웃하는 타 흡음체의 내부에 구비된 흡음판을 통한 흡음 효과도 얻고자 하는 목적도 있다.In addition, there is also an object to obtain a sound absorbing effect through the sound absorbing plate provided in the side of the other sound absorbing body by forming one or more through holes in the side wall constituting the sound absorbing body.
또 전방의 각 모서리의 내측에는 공기층과 관통되는 관통홀을 추가로 형성시켜 공기층에 유입되는 음파의 유입량을 극대화함으로서 흡음 효과를 좀더 증폭시킬 수 있는 목적도 있다.In addition, the inside of each corner in front of the air layer and the through-hole further formed to maximize the amount of sound waves flowing into the air layer has the purpose of further amplifying the sound absorption effect.
또 진동판의 중앙부를 후방 흡음판까지 함몰시키지 않음으로서 공기층의 부피를 확장시킴으로서 공기층의 용수철진동 현상을 증폭시켜 음파의 소멸효과를 극대화 하고자 하는 목적도 가지는 것이다.In addition, it is also intended to maximize the extinction effect of sound waves by amplifying the spring vibration phenomenon of the air layer by expanding the volume of the air layer by not recessing the center portion of the diaphragm to the rear sound absorbing plate.

Periphery of the periphery and the periphery of the periphery is formed between each of the sound absorbing portion 22 consisting of a plurality of curved plate 221 forming a spiral combination and the curved plate 221 formed through the sound wave to pass the air layer A diaphragm 2 composed of an opening 23 formed to be introduced into the 11 and a rear sound absorbing plate 3 mounted on the rear of the frame 1 to absorb sound waves passing through the air layer 11. In the sound absorbing body,
상기 공기층(11)의 내측 둘레인 측벽(12)의 내측면에는 다공부를 가지는 측 흡음판(4)이 장착되어 있는 것이다.The side sound absorbing plate 4 having the porous portion is mounted on the inner surface of the side wall 12 which is the inner circumference of the air layer 11.
그리고 상기 굴곡격판(221)들의 외측인 전방 둘레에는 상기 공기층(11)의 둘레에 장착된 측 흡음판(4)으로 음파가 직접적으로 유입될 수 있도록 하나 이상의 흡수 관통홀(5)이 형성되어 있는 것이다.In addition, at least one absorption through hole 5 is formed at a front circumference of the curved plate 221 so that sound waves can be directly introduced into the side sound absorbing plate 4 mounted around the air layer 11. .
또한 상기 측벽(12)들에는 이웃하는 타 흡음체의 내부에 구비된 측 흡음판(4)을 통한 흡음 효과도 얻을 수 있도록 하나 이상의 통과 관통홀(6)이 형성되어 있는 것이다.In addition, at least one through-hole 6 is formed in the sidewalls 12 so as to obtain a sound absorbing effect through the side sound absorbing plate 4 provided in the neighboring sound absorbing body 4.
또 상기 흡음체 전방의 각 모서리 내측에는 공기층(11)과 관통되어 측 흡음판(4) 및 후방 흡음판(3)의 흡음 효과를 증폭시킬 수 있도록 다수의 유입 관통홀(7)이 형성되어 있는 것이다.In addition, a plurality of inflow through-holes 7 are formed inside each corner in front of the sound absorbing body to amplify the sound absorbing effect of the side sound absorbing plate 4 and the rear sound absorbing plate 3.
또 상기 후방 흡음판(3)의 중앙에는 측벽의 폭 보다 상대적으로 짧은 길이 지지봉(8)이 장착되어 상기 진동판(2)을 구성하는 중앙판(21)이 지지봉(8)의 끝단에 함몰되게 고정됨으로서, 상대적으로 공기층(11)의 부피를 확장시켜 용수철진동 현상을 증폭시켜 음파의 소멸효과를 극대화시킬 수 있는 것이다.In addition, the support plate 8, which is relatively shorter than the width of the side wall, is mounted at the center of the rear sound absorbing plate 3 so that the center plate 21 constituting the diaphragm 2 is fixed to the end of the support bar 8 by being recessed.

또 전방의 각 모서리의 내측에는 공기층과 관통되어 음파가 공기층(11)의 내부에 직접적으로 유입되는 유입 관통홀(7)을 형성시켜 공기층(2)으로 유입되는 음파의 양을 늘려 음파의 소멸효과를 향상시킬 수도 있는 것이다.In addition, the inside of each corner in front of the air layer penetrates the air through the air inlet 11 through the inlet through hole 7 is formed to increase the amount of sound wave introduced into the air layer 2 to eliminate the sound wave effect It can also improve.
한편, 도 5는 도 4의 B-B선 단면도로서, 상기 흡음체를 구성하는 측벽에는 하나 이상의 통과 관통홀(6)을 형성시켜 이웃하는 타 흡음체의 내부에 구비된 측 흡음판(4)의 음파 흡수 소멸효과를 더불어 얻을 수 있는 것이다.FIG. 5 is a cross-sectional view taken along line BB of FIG. 4, wherein at least one through-hole 6 is formed in the sidewall constituting the sound absorbing body to absorb sound waves of the side sound absorbing plate 4 provided in the neighboring sound absorbing body. It can be obtained with an extinction effect.
상술한 바와 같이 본 고안은, 흡음체를 구성하는 공기층의 내측 둘레에 다공부를 가지는 흡음판을 장착함으로서 음파의 소멸효과를 극대화 할 수 있는 효과를 가지는 것이다.As described above, the present invention has an effect of maximizing the extinction effect of sound waves by mounting a sound absorbing plate having a porous portion in the inner circumference of the air layer constituting the sound absorbing body.
또한 전방에 형성된 굴곡격판의 주위에는 공간부의 둘레에 측 흡음판의 내부로 음파가 유입되는 다수의 흡수 관통홀을 형성시켜 측 흡음판의 음파 흡수소멸효과을 증폭시킴으로서, 흡음체의 음파 소멸효과를 극대화 할 수 있는 것이다.In addition, by forming a plurality of absorption through-holes in which sound waves are introduced into the side of the side sound absorbing plate around the curved plate formed in the front part, the sound absorbing effect of the sound absorbing body can be maximized by amplifying the sound absorbing effect of the sound absorbing body. It is.
또 흡음체를 구성하는 측벽에는 하나 이상의 관통홀을 형성시켜 이웃하는 타 흡음체의 내부에 구비된 흡음판의 흡음효과를 추가로 얻음으로서, 흡음체의 음파 소멸효과를 좀더 향상시킬 수 있는 효과도 있다.In addition, by forming one or more through-holes on the sidewalls of the sound absorbing body, the sound absorbing effect of the sound absorbing plate provided inside the neighboring sound absorbing body is additionally obtained, thereby further improving the sound wave extinction effect of the sound absorbing body. .
또 전방의 각 모서리의 내측에는 공기층과 관통되는 관통홀을 추가로 형성시켜 공기층으로 음파의 유입량을 극대화함으로서 흡음재를 통한 흡음효과를 좀더 증폭시킴으로서, 흡음체의 음파 소멸효과를 좀더 향상시킬 수 있는 효과도 있다.In addition, the inside of each corner in front of the air layer and penetrating through holes to maximize the inflow of sound waves into the air layer by further amplifying the sound absorbing effect through the sound absorbing material, thereby further improving the sound wave extinction effect of the sound absorbing body There is also.
또 흡음체를 구성하는 공기층의 부피를 확장시켜 공기층의 용수철진동 현상을 증폭시킴으로서, 음파의 소멸효과를 좀더 극대화 하고자 할 수 있는 효과도 있다.In addition, by expanding the volume of the air layer constituting the sound absorbing body to amplify the spring vibration phenomenon of the air layer, there is an effect that can further maximize the extinction effect of sound waves.
