Description

방음부스{Soundproof Booth}Soundproof Booth

본 발명은 방음부스에 관한 것으로, 더욱 상세하게는 방음부스의 측벽부를 제작하는 방음패널의 내측으로 차음판을 더 설치하여 방음 성능을 향상시킨 방음부스에 관한 것이다. The present invention relates to a soundproofing booth, and more particularly, to a soundproofing booth having improved soundproofing performance by further installing a soundproofing plate inside a soundproofing panel for manufacturing the sidewall of the soundproofing booth.

일반적으로 방음부스는 외부의 소리가 내부로 유입되는 것을 차단하여 외부 소음으로부터 방해받지 않거나, 혹은 내부의 소리가 외부로 흘러나가는 것을 차단하여 자기만의 독립된 공간을 확보하여 주위의 다른 사람들에게 소음 피해를 주지 않고 노래연습, 음악감상, 악기연주 등과 같은 다양한 목적과 다양한 용도로 활용할 수 있는 공간을 말한다.In general, soundproof booths block external sounds from entering the interior so that they are not disturbed by external noise, or they block internal sounds from flowing to the outside to secure their own independent space and cause noise damage to others around them. It refers to a space that can be used for a variety of purposes and for various purposes, such as singing practice, listening to music, and playing an instrument, without giving it away.

이러한 방음부스는 악기나 보컬 연습, 녹음 등과 같이 특수 목적 이외에도, 집중력이 요구되는 수험생이나 홈시어터 등을 구축하여 영화를 감상하는 사용자들을 위해 가정집에 설치되어 사용되고 있으나, 설치 비용과 설치시간이 많이 소요되고, 설치 후 이사갈 때 철거비용이 추가로 발생되기 때문에 보급 확대에 한계가 있다.These soundproof booths are installed and used in homes for students who need concentration, or users who build home theaters and watch movies, in addition to special purposes such as musical instruments, vocal practice, and recording, but installation costs and installation time are high. There is a limit to the expansion of distribution because additional demolition costs are incurred when moving out after installation.

이러한 방음부스의 일례들이 대한민국 등록실용신안 제20-0347868호(등록일: 20040406), 대한민국 등록실용신안 제20-0347854호(등록일: 20040406), 대한민국 등록특허 제10-1109854호(등록일: 20120118) 등을 포함하여 다수의 선행문헌들에서 제안된 바 있었다.Examples of such soundproof booths are Republic of Korea Utility Model Registration No. 20-0347868 (registration date: 20040406), Republic of Korea Utility Model Registration No. 20-0347854 (registration date: 20040406), Republic of Korea Patent Registration No. 10-1109854 (registration date: 20120118), etc. It has been suggested in a number of prior literatures, including

상기한 선행문헌들에서 제안된 방음부스들은 방음부스의 벽체를 합성수지를 이용하여 규격화된 방음판넬로 분할 제작하고, 이들을 상호 조립하는 방식으로 설치함에 따라 방음부스를 원하는 형태와 크기로 간편하게 조립할 수 있고, 또한 필요에 따라 확장 또는 축소가 가능하여 이동 설치 및 보관이 용이한 이점을 제공하였다. The soundproof booths proposed in the preceding documents are manufactured by dividing the wall of the soundproofing booth into standardized soundproofing panels using synthetic resin, and by installing them in a mutually assembling manner, the soundproofing booth can be easily assembled into a desired shape and size. , and can be expanded or reduced as needed, providing the advantage of easy installation and storage.

그러나 상기 선행문헌들에서 제안된 방음부스들은 벽체가 아크릴과 같은 합성수지로 이루어짐에 따라 차음 및 흡음 효과가 미흡하였고, 고중량의 강화유리를 사용하는 경우에는 파손으로 인해 취급이 번거로워 조립 및 해체가 어려운 문제가 있었다. 또한, 내부 소리가 벽체를 통해 반사되어 잔향(반사음)이 생성됨에 따라 최적화된 방음공간을 제공하는데 한계가 있었다. However, the soundproof booths proposed in the preceding documents had insufficient sound insulation and sound absorption effects as the walls were made of synthetic resin such as acrylic. there was In addition, there is a limit in providing an optimized soundproof space as internal sound is reflected through the wall to generate reverberation (reflection sound).

특히, 상기 선행문헌들에서 제안된 방음부스들은 방음부스의 핵심 기능인 방음 성능을 향상시키기 위해서는 두께를 두껍게 하여야만 되는 문제점이 있었다. In particular, the soundproof booths proposed in the preceding documents had a problem in that the thickness had to be increased in order to improve the soundproofing performance, which is a core function of the soundproof booth.
