Abstract: A mobile terminal and a mobile terminal antenna production method. The mobile terminal uses an insulation film layer on an insulation rear housing as a carrier of a radiating element of an antenna, and the radiating element is located within the entire mobile terminal, thereby effectively increasing a height of the radiating element of the antenna relative to a circuit board with the antenna not affecting an appearance of the mobile terminal. Compared with a conventional support solution, this manner can increase a height of about 0.2 mm to 0.6 mm This reduces an impact caused by a metal component on the circuit board on antenna radiation, and further increases a bandwidth and efficiency of the antenna so that the antenna can cover a frequency band used in a handheld communications system.

Abstract: An unlocking apparatus which includes a circuit board, a snap-on structure, and a shape memory alloy strip. The circuit board is configured to supply power to the shape memory alloy strip, the snap-on structure is fixedly connected to the shape memory alloy strip, and after being powered on, the shape memory alloy strip deforms, so that the snap-on structure is driven to move and to be unbuckled from a card slot of a locked component. In the foregoing structure, components for driving unlocking are merely the shape memory alloy strip and the circuit board supplying power to the shape memory alloy strip, greatly simplifying the entire unlocking structure.
