Abstract

The invention discloses a mobile terminal including a display screen, a non-metallic member and a metal back cover mounted on a side of a non-display surface of the display screen. The non-metallic member is located between the metal back cover and the display screen. A groove is disposed in the surface at a side, facing the metal back cover, of the non-metallic member. The metal back cover covers the opening of the groove and forms a resonant cavity with the groove. By forming a cavity structure in the mobile terminal, a low-frequency signal is double-resonated, thereby increasing the low-frequency bandwidth, improving the low-frequency signal receiving performance of the mobile terminal, improving the call quality of users, and satisfying the demand of overseas projects for multi-band signals.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile terminal. Background technique [0002] With the development of science and technology and the higher and higher signal requirements of users for electronic products, many mobile terminals with antennas such as mobile phones on the market currently use metal shells to ensure the strength of use while satisfying the texture and improving the user experience. feel. As we all know, metal is a signal shielding material. In order to avoid the signal shielding of the metal casing from affecting the antenna efficiency, the casing is usually designed to combine metal and non-metal, so that the antenna structure is located in the non-metal area. The non-metal area is usually set at both ends of the mobile terminal. Located outside the shielded display area, a circuit board is installed inside the non-metal area, and electronic components and signal transceiver mod...
