Abstract: A mobile device includes a system circuit board, a metal frame, one or more other antenna elements, a display device, a first feeding element, and an RF (Radio Frequency) module. The system circuit board includes a system ground plane. The metal frame at least includes a first portion and a second portion. The metal frame at least has a first cut point positioned between the first portion and the second portion. The metal frame further has a second cut point for separating the other antenna elements from the first portion. The first cut point is arranged to be close to a middle region of the display device. The first feeding element is directly or indirectly electrically connected to the first portion. A first antenna structure is formed by the first feeding element and the first portion.

Abstract: A key structure comprises a baseplate, a film circuit board, an elastic body and a keycap. The film circuit board includes a deformation region and a support region. The support region is disposed on the baseplate, and a deformation space is formed between the deformation region and the baseplate. The elastic body is disposed on the film circuit board. The keycap is disposed on the elastic body.

Abstract: The disclosure discloses a keyboard key structure. The keyboard key structure includes a switch circuit board, a first luminescent circuit layer, a switch element, and a keycap. The first luminescent circuit layer is disposed on the switch circuit board, and includes a plurality of miniature light emitting diodes. The switch element passes through the first luminescent circuit layer and is configured to contact the switch circuit board. Two of the plurality of miniature light emitting diodes are respectively located on two opposite sides of the switch element. The keycap is connected to the switch element and covers the plurality of miniature light emitting diodes. The keycap further has at least one light transmissive portion.

Abstract: A keyboard module pivotally connected to an electronic device is provided. The keyboard module comprises a bottom plate, a plurality of keys, a keyboard frame and a hinge structure. The plurality of keys are disposed on the bottom plate. The key includes a keycap and a support member for connecting the keycap to the bottom plate. The keyboard frame includes a plurality of openings to expose the keycaps. The hinge structure pivotally connects a display module of the electronic device with the keyboard frame or the bottom plate. When the display module rotates to drive the keyboard frame (or the bottom plate), the keycap moves relative to the keyboard frame (or the bottom plate). An electronic device including the keyboard module is also provided.

Abstract: A key testing device is for testing a key with a keycap. The key testing device includes a loading unit and a sleeve. The loading unit includes a block and a rod. The rod includes a first end and a second end. The first end is detachably connected the block. The sleeve is sleeved around the loading unit, and the sleeve includes a partition plate with a through hole. The second end can pass through the through hole. When the sleeve is above the key and the second end contacts the keycap, the gravity of the loading unit is turned from the partition plate to be applied on the keycap. Consequently, since the key testing device can make the pressure pressing on the key be accurate via a loading unit, the probability of misjudgment is decreased.
