Abstract

The embodiments of the invention provide a mobile terminal which includes a metal rear cover, a mainboard, and a loudspeaker support. The mobile terminal is characterized in that the loudspeaker support has a tune trope which is externally provided with a through hole. The side of the loudspeaker facing towards the metal rear cover is provided with a first metal area, and the side of the loudspeaker support facing away from the metal rear cover is provided with a second metal area. The through hole enables communication between the first metal area and the second metal area. The metal rear cover and the first metal area are communicated. The mainboard is provided with a spring thereon. The spring abuts against the second metal area. According to the embodiments of the invention, the mobile terminal is intended for addressing the problem of voice leaking in the periphery of the through hole of the tune trope after sealing caused by the fact that the grounding of the metal rear cover requires penetration of the through hole of the tune trope.

Description

technical field [0001] The invention relates to the field of mobile terminal structure design, in particular to a mobile terminal. Background technique [0002] With the popularization of integrated metal technology, more and more alloy materials are applied to the front shell and back cover of mobile terminals. However, the unique magnetism of the metal alloy material will greatly interfere with the performance of the radio frequency antenna of the mobile terminal and affect the call quality of the mobile terminal. [0003] In the prior art, the electromagnetic interference problem is solved by grounding the metal back cover, specifically, by setting a shrapnel at a designated position on the motherboard, and opening a hole in the speaker bracket so that the shrapnel touches the metal back cover through the opening superior. Because the position of the shrapnel on the main board has been fixed in advance, the position of the shrapnel corresponding to the hole must be in t...
