An electronic device is able to be embedded in a mobile device with a plurality of antennas. The antennas are electrically coupled to the electronic device through a connector. The electronic device includes a plurality of built-in antennas, a communication processor, a plurality of antenna switching circuits, and a control processor. The built-in antennas receive a wireless mobile communication signal. The communication processor calculates the reception strength of the wireless signal received by each of the built-in antennas or each of the antennas. Each of the antenna switching circuits is electrically coupled to one of the built-in antennas or one of the antennas according to a control signal. The control processor correspondingly outputs the control signal according to the reception strength of the wireless signal received by the built-in antenna and the antenna.

A keyboard device includes an operation surface. One long side of the operation surface is referred to as a proximal side, which nears a user operating the keyboard device; and the other long side is referred to as a distal side. A key unit is positioned on the proximal side, wherein the key unit includes a plurality of keys. A camera module is positioned on the distal side. An angle between a border of a field of view of the light sensor and the operation surface is set at a particular angle thus user's hand lays outside the field of view of the light sensor when the user is manipulating the key unit.

A portable electrical device includes a tablet PC, a bottom plate, a support arm and a pivot portion. The tablet PC includes a breach and a first magnetic inducing member arranged inside the breach. One end of the support arm is pivoted to the bottom plate, and the other end of the support arm is pivoted to the pivot portion, and the other end of the pivot portion is with a second magnetic inducing member. When the second magnetic inducing member is moved into the breach to magnetize the first magnetic inducing member, the tablet PC is securely coupled with the pivot portion so that the tablet PC can be rotated; on the contrary, when the second magnetic inducing member is removed from the breach, the tablet PC can be totally independent to the support arm and the bottom plate.

A virtual control device is provided for an electronic device. The virtual control device includes a first lens, a second lens, a first photosensitive unit, a second photosensitive unit and a processor unit. The first photosensitive unit is arranged behind the first lens by a focal length, and obtains a first image via the first lens. The second photosensitive unit is arranged behind the second lens by the focal length, and obtains a second image via the second lens. The processor unit determines the object-position coordinates of a virtual control plane according to a first position of the projection of the object on the first photosensitive unit and a second position of the projection of the object on the second photosensitive unit, and the processor unit provides the object-position coordinates to the electronic device.
