Embodiment
The invention provides a kind of headset detection processing method based on mobile terminal and mobile terminal, for making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In order to solve due to the iPhone wire control earphone microphone problem that microphone cannot normally work in the mobile terminal of non-iPhone mobile phone, first the present invention detects whether earphone inserts mobile terminal, again after the earphone of detection insertion mobile terminal is iPhone wire control earphone, when needing the microphone using described iPhone wire control earphone, the first predetermined voltage for starting described microphone is loaded to it; After the microphone of described iPhone wire control earphone is started working, control to stop loading described first predetermined voltage, continue to load the second predetermined voltage to described microphone, make microphone keep normal work.So just can solve mobile terminal well cannot the problem of compatible iPhone wire control earphone microphone, such that whether the earphone no matter inserting mobile terminal is iPhone wire control earphone, normally can both use microphone.
Refer to Fig. 1, Fig. 1 is the headset detection process flow figure based on mobile terminal provided by the invention, comprises the following steps:
Whether step S100, mobile terminal detect has the earphone of band microphone to insert, and when mobile terminal detects that the earphone of band microphone inserts, detects and judges that the microphone path of the earphone of this insertion is whether as open-circuit condition;
Step S200, after judging that the microphone path of earphone of this insertion is as open-circuit condition, then judge that the earphone of current insertion is as iPhone wire control earphone;
Step S300, when described mobile terminal needs the microphone using described iPhone wire control earphone, control to load the first predetermined voltage for starting described microphone to the microphone of described iPhone wire control earphone;
Step S400, after the microphone of described iPhone wire control earphone is started working, control to stop loading described first predetermined voltage, continue to load the second predetermined voltage to described microphone, make microphone keep normal work.
Below above-mentioned steps is described in detail.
In the step s 100, whether Test earphone inserts in mobile terminal.In the present embodiment, whether no matter whether earphone is iPhone wire control earphone, first detect in the earphone interface of mobile terminal and have earphone to insert, and detects and judge that the microphone path of earphone of this insertion is whether as open-circuit condition.
In step s 200, if the earphone inserting mobile terminal is iPhone wire control earphone, due to the microphone of iPhone wire control earphone being in series with an application-specific integrated circuit, make the resistance value on microphone path very high, be about 3.97M ohm, microphone path is high-impedance state, i.e. open-circuit condition.In the present embodiment, after judging that the microphone path of earphone of this insertion is as open-circuit condition, then judge that the earphone of current insertion is as iPhone wire control earphone.
In step S300, when described mobile terminal needs the microphone using described iPhone wire control earphone, control, to first predetermined voltage of the microphone of described iPhone wire control earphone loading for starting described microphone, the microphone of described iPhone wire control earphone to be started working.In the present embodiment, the magnitude of voltage that described first predetermined voltage is is more than or equal to 2.5V, after loading the first predetermined voltage to the microphone of described iPhone wire control earphone, on the path of the microphone of iPhone wire control earphone, resistance can reduce greatly, for normal microphone resistance, be about 1.2K ohm, microphone path shows as conducting state, like this IC connected with the microphone of iPhone wire control earphone is activated, microphone is started working.
In step S400, after the microphone of described iPhone wire control earphone is started working, control to stop loading described first predetermined voltage, continue to load the second predetermined voltage to described microphone, make microphone keep normal work.In the present embodiment, the magnitude of voltage of described second predetermined voltage is more than or equal to 1.5V, after the microphone of iPhone wire control earphone is started working, as long as keep the voltage on described microphone to ensure to be more than or equal to 1.5V, namely continue loading second predetermined voltage, so the microphone of iPhone wire control earphone will keep normal work.
Further, described step S200 also comprises: when detecting and judging that the microphone path of the earphone of this insertion is as conducting state, and microphone path resistance is 0.7K-2.2K ohm, then judge the earphone of the earphone of the current insertion of mobile terminal as common band microphone, control to enter normal running flow process.The earphone of described common band microphone is non-iPhone wire control earphone.The earphone that described normal running flow process is common band microphone inserts after mobile terminal, normal with mobile terminal alternately, without the need to operations such as on-load voltages.In the present embodiment, when the microphone path of earphone insertion being detected is conducting state, the resistance of microphone path is generally 0.7K-2.2K ohms, then show that the earphone inserted is the earphone of common band microphone, i.e. non-iPhone wire control earphone, so mobile terminal enters normal running flow process, i.e. Row control earphone conveniently, normally uses this plugged earphone.
Further, described step S300 also comprises: the load time controlling to load described first predetermined voltage to the microphone of described iPhone wire control earphone is 10ms.In the present embodiment, this load time can regulate according to the actual needs.
Further, in described step S400, the magnitude of voltage of described second predetermined voltage is 1.8V.
Preferably, the headset detection processing method based on mobile terminal provided by the invention, after step S400, also comprises:
Step S500, after detecting that described iPhone wire control earphone is pulled out, control stop load described second predetermined voltage.In the present embodiment, after described iPhone wire control earphone is pulled out, control to stop loading described second predetermined voltage, avoid wasting energy, described mobile terminal waits for that again plugged earphone is to trigger above-mentioned steps.
Preferably, between step S400 and step S500, also comprise:
S401, after detecting that the voltage on described microphone is less than one the 3rd predetermined voltage, return step S300.Wherein, the magnitude of voltage of described 3rd predetermined voltage is 1.5V.In the present embodiment, when the voltage on microphone is less than the 3rd predetermined voltage, namely after 1.5V, the microphone inserting the iPhone wire control earphone of mobile terminal cannot normally work, and so returns step S300, loads the first predetermined voltage for starting described microphone to the microphone of described iPhone wire control earphone, wherein, the magnitude of voltage of described first predetermined voltage is more than or equal to 2.5V, reactivates the IC connected with the microphone of iPhone wire control earphone, thus microphone is started working again.
Headset detection processing method based on mobile terminal provided by the invention, efficiently solve because the iPhone wire control earphone microphone IC that connects makes iPhone wire control earphone insert the problem that normally cannot use microphone function after in mobile terminal, its implementation is simple, and can not hardware cost be increased, make iPhone wire control earphone after the mobile terminal being inserted into non-iPhone mobile phone, the microphone of iPhone wire control earphone also can normally work, like this, no matter user inserts whether the earphone of mobile terminal is iPhone wire control earphone, can both normally use its microphone function, substantially increase the experience sense of user, facilitate greatly for user brings.
