Abstract

The embodiment of the invention provides a mobile terminal and a method for improving call quality, relates to the technical field of communication, and aims to solve the problem that the call qualityis reduced due to the fact that the call function of the mobile terminal is interfered in a charging scene. The charging circuit of the mobile terminal comprises a first switch, an inductor connectedwith the first switch, a second switch, a switch controller and a plurality of capacitors. The second switch comprises an input end and a plurality of output ends, the input end is connected betweenthe first switch and the inductor, the plurality of output ends are in one-to-one correspondence with the plurality of capacitors, and each output end is connected with one end of the corresponding capacitor. The switch controller is connected with the second switch, and the switch controller is used for controlling the input end to be communicated with any output end. And the other ends of the plurality of capacitors are connected in parallel, and the plurality of capacitors are grounded after being connected in parallel. The mobile terminal in the embodiment of the invention is used for a communication scene.

Description

technical field

[0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a mobile terminal and a method for improving call quality. Background technique

[0002] As the functions of mobile terminals are gradually enriched, the application range of mobile terminals is more extensive. Therefore, people use mobile terminals more and more frequently, which leads to faster power consumption of mobile terminals, so that mobile terminals spend more and more time in charging scenarios. many.

[0003] When the mobile terminal is charging, the charging current will interfere with other functions of the mobile terminal. For example, the frequency multiplication of the clock generated by the charging current falls into the RF receiving frequency band occupied by the call function, thereby reducing the receiving sensitivity of the mobile terminal, thereby reducing the success rate of calling and being called by the user, an...
