Abstract

The present invention is applicable to the technical field of communication electronic equipment. The present invention provides a mobile terminal and a control method thereof. The mobile terminal includes: a Micro USB interface module, an audio switch module, a control module, an audio transcoder, an isolation switch module, and a charging module And the battery; when the earphone is connected, the control module controls the audio switch module to be turned on, so that the audio signal output end of the audio transcoder is connected with the audio input end of the earphone, and drives the audio switch module to output a charging shutdown signal, isolating The switch module cuts off the path between the Micro USB interface module and the charging module according to the charging shutdown signal, by setting a charging channel independent of the switching switch module, and by setting an isolating switch module in the charging channel, the problem existing in the prior art is solved. The MIC signal of the earphone is affected by the charging path, which causes the audio signal to be damaged.

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 ...
