Abstract: In a method for transferring data via a digital television (DTV) network and a mobile communication network using an electronic device, the method receives a DTV signal via the DTV network and detects a decode error rate (DER) of the DTV signal at a first frequency. The method further detects the DER of the DTV signal at a second frequency and detects an average signal strength of the mobile communication network when the DER is continuously greater than a first threshold value. The method builds an electronic connection between the electronic device and a multimedia server via the mobile communication network and receives multimedia data from the multimedia server when the DER is continuously greater than a second threshold value and when the average signal strength is continuously greater than a third threshold value.

Abstract: A speaker module includes a speaker, a bracket and a pair of conductive pins. The bracket holds the speaker. The pair of pins is arranged diagonally on the corners of the bracket and is configured for mounting to and electrically connecting the speaker with a PCB.

Abstract: In a navigation method for tracking a second electronic device using a first electronic device, the first electronic device receives position information of the second electronic device. A position of the second electronic device is marked on a navigation map stored in the first electronic device. The first electronic device is directed to track the second electronic device according to the marked position on the navigation map.

Abstract: A slidable assembly for an electronic device includes a housing, a slidable button, and a stopper. The housing defines a receiving groove, a slot, and a plurality of ports. The slidable button is slidably received in the receiving groove, and includes a seal ring for sealing the plurality of ports. The stopper is attached to the slot of the housing for abutting one side of the slidable button and stopping the slidable button from sliding out of the receiving groove. The slidable button is slid in the receiving groove to expose or cover the plurality of ports.

Abstract: A wire arrangement structure includes a first fixed rod, a second fixed rod, a movable rod, a wire, and an elastic member. The elastic member is connected to the movable rod. When the second fixed rod slides relative to the first fixed rod, the elastic member provides a force to move the movable rod to adjust the length of the wire.

Abstract: In a method to unlock a touch screen of an electronic device, a press operation is received from the touch screen pressed by a user. The touch screen includes an unlocking interface. The method determines whether the press operation is within a press area of the unlocking interface. When the press operation is within the press area, the method further controls an indicator of the unlocking interface to move at a default speed, and locates a stop position of the indicator on the touch screen when the indicator stops moving. The method unlocks the touch screen when the stop position is within a predefined area of the unlocking interface.
