Abstract

The invention is adaptive to the field of communication electronic equipment and provides a mobile terminal and a control method thereof. The mobile terminal comprises a Micro USB interface module, an audio switch module, a control module, an audio transcoding device, an isolation switch module, a charging module and a battery. When an earphone is connected to the mobile terminal, the control module controls the audio switch module to switch on so as to allow the audio signal output terminal of the audio transcoding device to communicate with the audio input terminal of the earphone and drives the audio switch module to output charging switching-off signals; the isolation switch module disconnects the Micro USB interface module and the charging module according to the charging switching-off signals; since a charging channel independent to the audio switch module is arranged, the isolation switch module is arranged in the charging channel, the problem that in the prior art, audio signals are damaged due to influence on MIC signals of the earphone by the charging channel is solved.

Description

technical field [0001] The invention relates to the technical field of communication electronic equipment, in particular to a mobile terminal and a control method thereof. Background technique [0002] With the rapid development of smart phones, people are not only satisfied with the realization of functions, but also put forward higher requirements for product differentiation and perfect vision. Among them, the ultra-thin mobile phone is a major demand of consumers. In order to achieve this goal, the height of the device must be evaluated from various aspects when designing a mobile phone. For example, the 3.5mm headphone jack is an important factor affecting the ultra-thin design of mobile phones. , in order to take into account the function and performance of the earphone, it is necessary to design the earphone interface and the USB socket multiplexed. For the 5pin USB socket, the MIC signal end of the earphone is usually selected to be multiplexed with the ID pin or the ...
