Abstract

The invention discloses a mobile terminal, relating to the field of communication technologies and used for solving the problem that thickness and audio performance of the mobile terminal in the priorart can be hardly considered at the same time. The mobile terminal comprises a shell, a sound production part and a daughter board circuit board are arranged in an internal space defined by the shell; the sound production part and the daughter board circuit board are arranged on a plane vertical to a thickness direction of the mobile terminal; the sound production part is electrically connected with the daughter board circuit board by virtue of a flexible connection device; and the sound production part and a shell part close to the sound production part jointly define a first resonant cavity, the daughter board circuit board and a shell part close to the daughter board circuit board jointly define a second resonant cavity, and the first resonant cavity and the second resonant cavity arecommunicated by virtue of a tunnel through hole formed in the shell.

Description

technical field [0001] The present invention relates to the communication field, in particular to a mobile terminal. Background technique [0002] There is a certain contradiction between the functionality and portability of mobile terminals. Constrained by the thickness of the terminal, some performance has to be compromised. For example, the sound resonance cavity of the speaker inside the mobile terminal cannot occupy a large volume, thereby greatly reducing the audio performance of the mobile terminal. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mobile terminal to solve the problem in the prior art that it is difficult to balance the thickness of the mobile terminal and the audio performance. [0004] In one aspect, the present invention provides a mobile terminal, comprising: a casing, a sounding part and a sub-board circuit board are arranged in an inner space surrounded by the casing; the sounding p...
