Abstract

The invention applies to the field of mobile terminals, and provides a method, a system and a mobile terminal for realizing the hand-free call of a mobile terminal headset. In the invention, when a user takes a three-segment headset to plug in a mobile terminal matched with a four-contact headset socket to realize the call, after the system for realizing the hand-free call of the mobile terminal headset detects that the mobile terminal is in a call state, the main microphone of the mobile phone is in a working state, accordingly, even if the three-segment headset does not support the sending function, the mobile terminal can also realize the receiving function of the headset and the hand-free call function of the sending of the main microphone, thereby facilitating users to use.

Description

technical field [0001] The invention belongs to the field of mobile terminals, and in particular relates to a method, a system and a mobile terminal for realizing hands-free calling with a mobile terminal earphone. Background technique [0002] As an important accessory of a mobile terminal, earphones have been widely used in people's daily life. Earphones can be divided into three-stage and four-stage types according to plugs. The three-segment earphone only supports the function of receiving calls, and the three-segment earphone plug is used in conjunction with the three-contact earphone socket. figure 1 Shows the structure of a three-segment earphone plug and a three-contact earphone socket, the three-segment earphone plug includes tip 1, middle ring 2 and end 3, and the three-contact earphone jack includes a left channel end 10 and a right channel end 20 , Ground terminal 30 and ground terminal 40, wherein, when the three-section earphone plug is fully inserted into the...
