Abstract: A chip card holder is secured to a circuit board. The chip card holder comprises a hollow frame including an opening, a first board, a second board opposite to the first board, two opposite sidewalls and an end board opposite to the opening. The frame has two securing blocks protruding from the first board toward the second board and two latching blocks protruding from the end board; the securing blocks and the latching blocks are for latching the chip card holder to the circuit board.

Abstract: A portable electronic device comprises a cover section, a body section, a tilting adjuster and a rotating adjuster. The body section is adjustably coupled with the cover section. One end of the tilting adjuster is hinged to the body section. One end of the rotating adjuster is hinged to the cover section, the other end of the rotating adjuster is hinged to the other end of the tilting adjuster.

Abstract: An electronic device includes a first housing, a second housing, a drive mechanism and a voice-activated module. The drive mechanism connects the first housing with the second housing. The voice-activated module control the drive mechanism to drive the first housing moving relative to the second housing.

Abstract: A connector is latched to a circuit board, the connector comprises a main body. The main body comprises two opposite ends, each end of the main body having a securing protrusion protruding therefrom, the securing protrusion for latching the connector to the circuit board.

Abstract: An electronic device includes a main body, a display module, a first magnet, a second magnet and a third magnet. The display module rotatably positioned on the main body includes a first surface and a second surface. The first magnet and the second magnet are positioned on one of the main body and the display module, and the third magnet is positioned on the other of the main body and the display module. The third magnet is an electromagnet. The third magnet can selectably face one of the first magnet and the second magnet by changing the polarity of the third magnet, thereby, the display module can rotate relative to the main body and can be fixed at a different position.
