110: 덕트
120, 130: 헬름홀츠 공명기
120a, 130a: 공동
140: 제1 그루브형 공명기
150: 제2 그루브형 공명기
Claims (3)
- 자동차의 터보 챠저 후방에 설치되어 흡기 소음을 저감시키는 공명기로서,
덕트 내부로 진행하는 공기 유입 경로에 대해 상기 덕트의 반경 방향으로 형성된 공동(cavity)을 갖는 하나 이상의 헬름홀츠 공명기; 및
상기 헬름홀츠 공명기의 후방에 구비되며, 상기 덕트의 반경 방향 외측으로 돌출하는 하나 이상의 그루브형(groove type) 공명기를 포함하며,
상기 헬름홀츠 공명기의 길이는 상기 공동을 기준으로 하여, 전방의 길이가 후방의 길이에 비해 짧은 것을 특징으로 하는 공명기. - 삭제
- 제 1 항에 있어서, 상기 그루브형 공명기는 상기 공기 유입 경로를 따라 순차적으로 형성되는 제1 그루브형 공명기와 제2 그루브형 공명기를 포함하며, 상기 제1 그루브형 공명기의 폭은 상기 제2 그루브형 공명기의 폭보다 좁고, 상기 제1 그루브형 공명기의 높이는 상기 제2 그루브형 공명기의 높이보다 높게 형성되는 것을 특징으로 하는 공명기.
