Abstract

The disclosure relates to an isolation control circuit and method and a mobile terminal. The circuit comprises a switching module, a decoupling module, and an earphone of which a distance with a first antenna is in a preset range; working frequency bands of the first antenna and a second antenna meet preset conditions; a first pin of the earphone is connected with the switching module, and the switching module selectively switches on the decoupling module; the switching module is configured to switch on the decoupling module when the first antenna works, and is configured to not switch on the decoupling module and control the earphone to normally work when the second antenna works; and the decoupling module is configured to eliminate coupling of the earphone on the first antenna. The isolation control circuit in the embodiment of the disclosure improves isolation of the first antenna and the second antenna in the mobile terminal and improves communication quality of the mobile terminal.

Description

technical field

[0001] The present disclosure relates to communication technology, and in particular to an isolation control circuit, method and mobile terminal. Background technique

[0002] With the continuous development of social economy, mobile terminals such as mobile phones have become indispensable tools in people's lives. People can make voice calls, chat online, shop, book tickets, etc. through mobile phones, which greatly facilitates people's lives.

[0003] The current mobile terminals are equipped with antennas of different standards. Due to the space limitation inside the mobile terminal, two antennas whose frequency bands are close but not completely overlapped are often close. Therefore, the problem of insufficient antenna isolation is prone to occur, resulting in The communication quality of the terminal is not high. Contents of the invention

[0004] In order to overcome the problems existing in related technologies, the present disclosure provides an is...
