일반적으로 종래의 자동차용 메인 소음기는 단순히 파이프 경로 변경 등을 통한 저주파 부밍과 고주파 기류음을 낮추는 것에만 관심을 가지고 있었으며, 아이들(IDLE) 및 저주파 부밍 감소를 위하여 배압 증대를 하게 되고, 이는 출력 저하 등의 악영향을 초래하게 되는 문제가 있었다.In general, the main car silencer of the prior art was interested only in lowering the low frequency and high frequency airflow by simply changing the pipe path, and increasing the back pressure to reduce the idle and the low frequency booming. There was a problem that causes adverse effects such as.

따라서 스포츠카에 있어서는 단순히 소음저감이 아닌 스포티 사운드를 구현할 수 있도록 하는 것이 바람직하다.Therefore, in the sports car, it is desirable to realize sporty sound instead of simply reducing noise.

본 발명에 있어서 제1챔버(31)와 제2챔버(32) 사이에 설치되는 제1배플(21), 그리고 제4챔버(34)와 제5챔버(35) 사이에 설치되는 제4배플(24)에는 각각 타공부(21a)(24a)가 마련된다. In the present invention, the first baffle 21 provided between the first chamber 31 and the second chamber 32, and the fourth baffle provided between the fourth chamber 34 and the fifth chamber 35 ( 24 is provided with perforations 21a and 24a, respectively.

또한 타공부(21a)가 형성된 제1배플(21)을 경계로 제1챔버(31)와 분리된 제2 챔버(32), 그리고 타공부(24a)가 형성된 제4배플(24)을 경계로 제5챔버(35)와 분리된 제4챔버(34)는 각각 특정 주파수를 잡는 헬름홀쯔 공명실 역할을 담당하게 된다.In addition, the second chamber 32 separated from the first chamber 31 and the fourth baffle 24 formed with the perforated part 24a are bounded by the first baffle 21 formed with the perforated part 21a. The fourth chamber 34, which is separated from the fifth chamber 35, serves as a Helmholtz resonance chamber that captures a specific frequency.

본 발명에 있어서는 제1출구파이프(51)의 제4챔버(34) 통과부위 및 제2출구파이프(52)의 제2챔버(32) 통과부위에 타공부(51a)(52a)가 형성되어 롱테일파이프(Long Tail Pipe) 구조에 있어서 기주 공명 주파수를 파기하는 역할을 하게 된다.In the present invention, the perforated portions 51a and 52a are formed at the passage portion of the fourth chamber 34 of the first outlet pipe 51 and the passage portion of the second chamber 32 of the second outlet pipe 52 to form a long tail. In the pipe structure (Long Tail), the role of destroying the host resonance frequency.

즉, 스포티 사운드의 경우 발진 부밍 증대로 외부 소음 법규를 만족하는 데에 어려움이 있는데, 본 발명에서는 각 출구파이프(51)(52)에 타공부(51a)(52a)를 마련하여 기주 공명 주파수를 파기할 수 있도록 하고, 그에 따라 아이들(IDLE) 부밍을 개선함은 물론 외부 소음 문제 영역 개선으로 법규를 만족할 수 있게 된다.That is, in the case of sporty sound, it is difficult to satisfy the external noise regulation by increasing the oscillation booming. In the present invention, perforated parts 51a and 52a are provided in each outlet pipe 51 and 52 to increase the host resonance frequency. It can be destroyed, thereby improving IDLE booming and satisfying the law by improving the area of external noise problem.
