| titleOfInvention | soundproof structure |
| abstract | The present invention provides a small soundproof structure with high soundproof performance in a low frequency band. The soundproof structure of the present invention has at least one soundproof unit including: a frame having a hole; an elastic layer laminated on the frame on one opening surface of the frame; and a film laminated on the elastic layer so as to cover the hole When the membrane vibration of the membrane occurs, the effective displacement at the position where the amplitude of the membrane becomes the largest in the region bonded to the elastic layer is 0.4% to 10% of the effective displacement at the position where the vibration of the membrane becomes the largest. |
