Problems solved by technology

In order to prevent the metal back cover from interfering with the antenna signal, the mobile terminal equipment of the related art usually has a non-metallic design on the part of the metal back cover opposite to the antenna module, and a metal wire design on the rest. Some boundaries exist, and the appearance of the shell cannot be guaranteed to have a high consistency, which affects the overall appearance of the mobile terminal device
Another improved mobile terminal device is to migrate the antenna module to the metal back cover as a whole, and use the metal back cover as the antenna radiator, but this structure has the defect that the antenna resonant frequency and bandwidth are difficult to adjust

Abstract

The invention provides a mobile terminal. The mobile terminal includes a shell having an accommodating space, and a mainboard and an antenna module which are accommodated in the accommodating space, the shell includes a metal rear cover which at least partially serves as a radiator of the antenna module and includes a first metal part, a second metal part and a third metal part which are arranged in mutual insulation coordination, the mainboard includes a grounding part and a feed part, the antenna module includes a grounding dynamic switch and a feed dynamic switch unit, the grounding dynamic switch unit is connected between the grounding part and the first metal part, one end of the feed dynamic switch unit is connected with the feed part, and the other end is selectively connected with the first metal part or the second metal part. In the mobile terminal provided by the invention, resonant frequency of the antenna module of the mobile terminal is adjusted through state cooperation of the grounding dynamic switch unit and the feed dynamic switch unit, thereby improving efficiency of an antenna.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a mobile terminal. Background technique [0002] With the continuous development of mobile terminal equipment such as mobile phones and tablet computers, people have higher and higher requirements for terminal signals, call effects and appearance of mobile communications. Mobile terminals with all-metal back covers are popular among consumers because of their metal texture, robustness, and wear resistance. [0003] However, the all-metal back cover will form a signal shielding effect on the antenna module in the mobile terminal device. In order to prevent the metal back cover from interfering with the antenna signal, the mobile terminal equipment of the related art usually has a non-metallic design on the part of the metal back cover opposite to the antenna module, and the rest of the metal wire design, but this design is due to the metal part and the non-meta...
