    摘要: A breather valve and a portable communication device including a breather valve are provided. The breather valve includes a housing having a bottom portion having an opening and side portions, a rigid substrate located within the housing and a breathable membrane mounted to the rigid substrate. The breather valve further includes a gasket having a top surface and a bottom surface, and a preloaded compression element across the gasket and the rigid substrate. The gasket has an upper energy director located at the top surface and a lower energy director located at the bottom surface. The preloaded compression element provides at least a first compressive position providing a contact between the lower energy director and the bottom portion of the housing and a second compressive position in which air passes around the lower energy director and the upper energy director.
