Abstract

The present invention provides a mobile terminal which relates to the technical field of electronics and solves the problems that the communication effect can be influenced by an existing dust prevention method of a mobile phone, or the dust prevention effect is poor due to the focus of electrostatic charge, and internal devices of the mobile phone can be damaged. The mobile terminal comprises a shell and a circuit board arranged inside the shell, wherein an electroacoustic transducer is arranged on the circuit board, and the ground of the circuit board is electrically connected with the shell; the shell is provided with an opening hole and a sound transmission channel which is penetrated to the electroacoustic transducer from the opening hole; and a dust prevention screen is arranged between the opening hole and the sound transmission channel, an anti-electrostatic material is arranged on the surface of the dust prevention screen, and the dust prevention screen is electronically connected with the shell. According to the scheme of the mobile terminal, the blockage caused by dust and impurities which are absorbed by the electrostatic charge can be reduced, and damages to the internal devices caused by electrostatic discharge can be avoided; and meanwhile, the sound transmission channel does not need to be extended, and the communication effect can be guaranteed.

Description

technical field [0001] The present invention relates to the field of electronic technology, and more specifically, to a mobile terminal. Background technique [0002] The microphone in the mobile phone must be connected to the outside world, so it is vulnerable to the influence of dust and impurities from the outside world, resulting in failure. Generally, by lengthening the sound guide channel or adding a dust-proof net to prevent dust and impurities from entering the microphone. However, since the extension of the sound guide channel will affect the call effect, and the dust-proof net itself will also accumulate electrostatic charges to attract dust and cause blockage, and because electrostatic discharge will cause damage to the microphone device, these two methods have certain limitations. Contents of the invention [0003] An embodiment of the present invention provides a mobile terminal to solve the problem that the existing dust-proof method for mobile phones will a...
