A breathable space is disposed in the base. The breathable space penetrates from the first surface to the second surface. The breathable space is located inside the decorating ring. The first adhesive layer is located inside the decorating ring and is connected to the first surface through fastening. The first adhesive layer forms a first channel connected to the breathable space. The cover is connected, through fastening, to a surface that is of the first adhesive layer and that faces away from the base. A first gap is formed between a peripheral side face of the cover and an inner side face of the decorating ring. The first gap is connected to the breathable space through the first channel. The waterproof breathable film is fastened onto the base and covers the breathable space. When the housing assembly having the decorating assembly is applied to the electronic device, the electronic device can quickly balance internal and external air pressure.
