Reacquire earphone keystroke trigger signal；If it is determined that the result that earphone keystroke state changes is yes, then into next step
Suddenly.
Step S430, earphone keystroke is interrupted and is triggered.
Four-wire system earphone is in order to take microphone (mic) call function, and last ring of four-wire system earphone heads can all connect
An analog-digital converter (ADC) is connect, the premise for we providing discriminating method is given in this ADC presence.
In the prior art, when earphone is inserted, the driving of script for the compatible four-wire system earphone on the basis of three-wire system earphone,
The timer of 6 seconds is started, if again without the presence for detecting four-wire system earphone Fourth Ring at the end of 6 seconds,
The button detection function of closing earphone will be given tacit consent to.And the presence of this button sense channel is also our new technical scheme wounds
Convenience is made.
Magnitude of voltage on step S440, test earphone analog-digital converter.
Step S450, determines whether effective button triggering.
Button on microphone (mic) circuit of earphone has concatenated an inductance filtered to mic in itself, and its resistance is very
Small, button normally presses the magnitude of voltage read after connection from ADC and there was only 8mV to 10mV, and this magnitude of voltage just provides electricity
Press the preset voltage value in comparison process.
And the toy trumpet of the left and right acoustic channels of earphone is the device that an internal resistance is 32 Ω in itself, during extraction on short circuit plug
Mic keys and ground wire after the magnitude of voltage that is read from ADC but have 20mV to 23mV.
Magnitude of voltage on analog-digital converter and preset voltage value are contrasted, when the magnitude of voltage on analog-digital converter does not exist
When within preset voltage value scope (8mV to 10mV), the triggering of this button is judged for false triggering, and enter step S470, shielding
This trigger signal simultaneously changes earphone state to extract；When the magnitude of voltage on analog-digital converter is within the scope of preset voltage value
When, judge that the triggering of this button is effective, then into step S460, make corresponding button triggering response.Wherein, button is triggered
Response includes the pause broadcasting of music, upper one bent, next bent control and connection or the process such as hang up the telephone.
So far, signal detection process idiographic flow when earphone is extracted terminates.
To the detection process of button trigger signal when earphone is extracted in the present embodiment, earphone not only can be normally recognized
Mobile phone is connect extremely caused by call function and button line traffic control function, button exception-triggered when can also avoid extracting earphone
Logical, phone is hung up and the problem of phone is hung up extremely by abnormal, in addition, when playing music or video, be also not in by
Earphone, which is extracted, causes pause, the problems such as switching backward.If not it is intentional in this way, earphone extract after music automatic pause
This common phenomenon would not occur in that.
Relative to prior art, the earphone operation detection method that the present invention is provided, when earphone is inserted, is temporarily inserted into earphone
The earphone in hole is used as four-wire system earphone and using the earphone as three-wire system earphone, while constantly the 4th pin of test earphone
