Disclosed are a method for producing a honeycomb sound insulation structure, a honeycomb sound insulation structure, a nacelle and an aircraft. The invention relates to a method for producing a honeycomb soundproof structure, wherein a portion of a membrane (21) of a diaphragm (20) comprising acoustic outlets (24) is inserted into holes (15) of a perforated membrane (14) covering cells (11) of the honeycomb structure (10), and the diaphragm (20) is pressed into the cells (11) and the perforated membrane (14) is deformed, and the diaphragm is fixed at the position. The invention also relates to a honeycomb sound insulation structure, an aircraft nacelle comprising such a honeycomb sound insulation structure and an aircraft comprising such a nacelle. This method enables different types of diaphragms to be inserted into cells of different configurations according to the sound frequency to be processed, and enables the diaphragms to be fixed in the cells.
生产蜂窝隔音结构的方法、蜂窝隔音结构、短舱和飞行器。本发明涉及一种用于生产蜂窝隔音结构的方法,其中包括声学出口(24)的隔膜(20)的薄膜(21)的一部分被插入到穿孔薄膜(14)的孔(15)中,所述穿孔薄膜覆盖所述蜂窝结构(10)的小室(11),并且所述隔膜(20)被压入所述小室(11)并且所述穿孔薄膜(14)发生变形,并且所述隔膜被固定在此位置处。本发明还涉及一种蜂窝隔音结构、包括这种蜂窝隔音结构的飞行器短舱以及包括这种短舱的飞行器。这种方法使得能够根据要处理的声音频率将不同类型的隔膜插入到不同构型的小室中,并且使得所述隔膜能够被固定在小室中。
