US 7,746,201 B2 · Portable electronic device with hall sensor

Abstract

A portable electronic device includes a cover section (54), a body section (52), a magnet (60) and a hall sensor (70). The cover section has a printed circuit board secured therein. The body section has a connecting portion, and the body section is rotatably connected to the cover section with the connecting portion. The magnet is secured in the connecting portion, and the hall sensor is electrically attached to the printed circuit board. The magnet acts on the hall sensor according to relative rotation between the cover section and the body section, thereby switching the portable electronic device to a work mode when the cover section is opened away from the body section or a power save mode when the cover section is closed to the body section.
