    • Disclosed is a diaphragm having a flexible film portion and an outer peripheral flange portion integrally provided on the peripheral edge of the film portion, said outer peripheral flange portion being provided between and held by a first housing and a second housing, wherein the film portion is prevented from rising upward when the diaphragm is attached to the housings. The outer peripheral flange portion has a first pressed surface which is one surface of the diaphragm in the thickness direction and which is in close contact with the first housing, and a three-dimensional shape composed of a projected portion or a recessed portion, on the first pressed surface. When the outer peripheral flange portion is attached to the first housing and the second housing while being compressed and deformed therebetween, the three-dimensional shape defines voids in the thickness direction between the outer peripheral flange portion and the first housing.
    • 公开了一种膜片,其具有柔性膜部分和一体地设置在膜部分的周缘上的外周边凸缘部分,所述外周凸缘部分设置在第一壳体和第二壳体之间并由第一壳体和第二壳体保持,其中膜部分 当隔膜附接到壳体时,防止其向上升起。 外周凸缘部分具有第一挤压表面,该第一压制表面是厚度方向上的膜片的一个表面,并且与第一壳体紧密接触,并且具有由突出部分或凹入部分组成的三维形状 第一次按压表面。 当外周凸缘部分在第一壳体和第二壳体之间被压缩和变形地附接到第二壳体和第二壳体时,三维形状在外周凸缘部分和第一壳体之间限定厚度方向上的空隙。
