Abstract: A wearable electronic device includes a device body and a wearing element. The wearing element is connected to the device body. The device body includes a conductive upper cover, a conductive lower cover, an insulating frame and a circuit system. The insulating frame is disposed between the conductive upper cover and the conductive lower cover and forms an accommodating space therewith. The circuit system is disposed in the accommodating space. The conductive upper cover has a first feeding point. The conductive lower cover has a second feeding point. The circuit system is coupled to the first feeding point and the second feeding point respectively.

Abstract: An I/O shield used in an electronic apparatus is provided. The electronic apparatus comprises a casing having an opening. The I/O shield comprises a body and at least a flexible lateral plate. The body has an edge with many protrusions arranged thereon. The flexible lateral plate has a first lateral edge and a second lateral edge parallel to the first lateral edge. The first lateral edge is disposed on the edge. The flexible lateral plate tilts towards the protrusions, and a surface of the flexible lateral plate faces the protrusions. When a rim of the opening is situated between the protrusions and the flexible lateral plate, the flexible lateral plate forms a bend structure between the first lateral edge and the second lateral edge, so that part of the surface near the second lateral edge presses the rim and clamps the rim of the opening together with the protrusions.
