Abstract: An earphone receiving assembly for receiving an earphone includes a main body surrounding an accommodating space for receiving the earphone and defining an opening communicating with the accommodating space, a cover releasably locked in the opening, and a releasing assembly. The releasing assembly includes a fastening member secured to the main body and a rotating member rotatably assembled to the fastening member. The cover is slidably assembled to the rotating member. When the cover is released from being locked within the opening, the rotating member rotates and lifts the cover from the opening to expose the earphone.

Abstract: A control key assembly for an electronic device includes a housing and a control key. The housing forms a receiving portion defining an opening having two spaced-apart arms. The control key is received in the receiving portion. The control key includes a first hook and a second hook. The first hook and the second hook are slidably engaged in the opening, and alternatively latch with the two arms when the control key is slid between first and second positions.

Abstract: A chip card holder for holding a chip card is disclosed including a base member, a mounting frame and a holding member. The mounting frame is made of metal materials and secured to the base member. The holding member is used to hold the chip card and is slidably mounted within the mounting frame. When the holding member is completely received in the mounting frame, the mounting frame and the base member cooperatively enclose and preventing the chip card from electromagnetic interference.

Abstract: A portable electronic device includes a housing, a printed circuit board, a flexible printed circuit board, and a clip. The printed circuit board is attached to one side of the housing. The flexible printed circuit board is attached to another side of the housing. The clip is attached to the housing. The clip includes at least one arcuate portion, and the arcuate portion elastically presses the flexible printed circuit board to the printed circuit board.

Abstract: A mobile communication device includes a main body, a cover, a slide enabling assembly. The cover is attached to the cover. The slide enabling assembly is mounted between the base and the cover, the slide enabling assembly includes a retaining board mounted to the main body, a sliding board mounted to the cover, a bracket assembly and a button. The sliding board is slidably mounted to the retaining board by the bracket assembly; when the button is pushed, the bracket assembly impels the sliding board to slide and tilt relative to the retaining board so that the cover slides and tilts relative to the main body.

Abstract: A chip card retaining mechanism (200) used in an electronic device (100) includes a sliding seat (20) and a sliding member (30). The sliding seat includes a main body (22) and two vertical portions (242) extending, respectively, from two opposite sizes of the main body. Each vertical portion defines a guide slot (26). The main body defines an opening (222) for receiving a connector (104) of the electronic device. The sliding member includes a stopping portion (36) and a receiving groove (35) for receiving a chip card (102). The stopping portion is positioned on one end of the sliding member. A shaft (39) is mounted on another end of the sliding member, and the two respective ends thereof are inserted into a corresponding guide slot so that the sliding member is slidably attached to the sliding seat.

Abstract: A pivot switch mechanism (200) mounted on a shell (20) of an electronic device (300) includes a fixing portion (30) and an operating portion (40). The fixing portion (30) is mounted on the shell (20) and is connected with the operating portion (40) in a spring-biased manner. The fixing portion (30) defines a receiving hole (32) and two receiving grooves (28). The operating portion (40) includes two resisting columns (48) and at least one pivotal shaft (424). The operating portion (40) is located in the receiving hole (32). The at least one pivotal shaft (424) is received in the receiving grooves (28). When the operating portion (40) is pressed, the operating portion (40) rotates/pivots relative to the receiving grooves (28) via the at least one pivotal shaft (424). When the pressure on the operating portion (40) is released, the operating portion (40) returns to its original position.
