Pressure-resistant sound absorption structure with supporting structure

The invention discloses a pressure-resistant sound-absorbing structure with a supporting structure, and the structure comprises a substrate layer structure, and the outer surface of the substrate layer structure is fixedly connected with a sound-absorbing covering layer or a sound-absorbing wedge structure; the cavity is formed or not formed in the base layer structure and formed in the sound absorption covering layer and the sound absorption wedge structure, and the base layer structure seals the close end of the cavity; and the framework is arranged in the cavity and is used for supporting the inner wall of the cavity. The cavity in the sound absorption layer can be supported by the framework, so that the cavity structure is not prone to large deformation, and the acoustic performance of the cavity structure is guaranteed. 本发明公开一种具有支撑结构的耐压吸声结构，包括，基底层结构，外表面连接固定有吸声覆盖层或吸声尖劈结构；空腔，开设或不开设在基底层结构内，以及，开设在吸声覆盖层和吸声尖劈结构内，且基底层结构封闭空腔的靠近端；骨架，设置在空腔内且用于支撑所述空腔内壁。本发明能够实现利用骨架对吸声层内的空腔进行支撑，使得空腔结构不易产生较大形变，保证其声学性能。
