Claims (3)

1. Способ изготовления заготовки акустической структуры, в котором обеспечивают сотовый элемент, содержащий первую и вторую кромку, при этом указанный сотовый элемент дополнительно содержит ряд стенок, расположенных между указанными первой и второй кромками, при этом указанные стенки ограничивают ряд ячеек, в котором каждая указанная ячейка имеет площадь поперечного сечения, расположенную перпендикулярно к указанным стенкам, и глубину, ограниченную расстоянием между указанной первой и второй кромками, выполняют мембранные крышки, образованные листом эластичного материала, имеющего толщину и внешнюю границу, при этом указанный лист эластичного материала является достаточно упругим для того, чтобы его можно было свернуть и вставить в упомянутые ячейки с образованием упомянутых мембранных крышек, содержащих резонаторную часть, которая проходит поперечно относительно упомянутых ячеек и имеет внешний край, расположенный у упомянутых стенок, и фланцевую часть, проходящую параллельно упомянутым стенкам и содержащую стопорную поверхность, находящуюся во фрикционном контакте с указанными стенками, при этом указанная стопорная поверхность имеет ширину, при этом ширины стопорной поверхности и способности эластичного материала восстанавливать первоначальную форму достаточно для обеспечения фрикционного сцепления мембранных крышек со стенками ячеек, размещают мембранные крышки в ячейках таким образом, чтобы мембранные крышки зафиксировались на месте только посредством фрикционного сцепления мембранных крышек со стенками, перед выполнением мембранных крышек из листа эластичного материала, проводят обработку указанного листа эластичного материала, а фланцевую часть упомянутых мембранных крышек подвергают перфорации, отличающийся тем, что обработку листа эластичного материала осуществляют путем пропускания через каландр, а перед размещением мембранных крышек выполняют надрезы фланцевой части выкроек мембранных крышек до внешнего края резонаторной части.1. A method of manufacturing a blank of an acoustic structure in which a honeycomb element is provided comprising a first and second edge, wherein said honeycomb element further comprises a series of walls located between said first and second edges, said walls defining a number of cells in which each said the cell has a cross-sectional area perpendicular to the indicated walls, and the membrane covers the depth, limited by the distance between the specified first and second edges, lined with a sheet of elastic material having a thickness and an outer boundary, wherein said sheet of elastic material is sufficiently elastic so that it can be rolled up and inserted into said cells to form said membrane covers containing a resonator portion that extends transversely with respect to said cells and has an outer edge located at said walls and a flange portion extending parallel to said walls and having a locking surface located in the friction con a stroke with the indicated walls, while the specified locking surface has a width, while the width of the locking surface and the ability of the elastic material to restore its original shape is sufficient to ensure friction adhesion of the membrane covers with the walls of the cells, place the membrane covers in the cells so that the membrane covers are fixed in place only by means of friction engagement of the membrane covers with the walls, before performing the membrane covers from a sheet of elastic material, brabotku said sheet resilient material, and a flange portion of said membrane is subjected to perforation lids, characterized in that the elastic material sheet processing performed by passing through calender and operate incisions flange portion patterns membrane covers up the outer edge of the resonator portion before placing the membrane lids. 2. Способ изготовления заготовки акустической структуры по п. 1, отличающийся тем, что количество надрезов фланцевой части выкроек мембранных крышек равно 3.2. A method of manufacturing a blank of an acoustic structure according to claim 1, characterized in that the number of notches of the flange portion of the patterns of the membrane covers is 3. 3. Способ изготовления заготовки акустической структуры по п. 1, отличающийся тем, что количество надрезов фланцевой части выкроек мембранных крышек равно 6.3. A method of manufacturing a blank of an acoustic structure according to claim 1, characterized in that the number of notches of the flange portion of the patterns of the membrane covers is 6.
