Based on above-mentioned mobile terminal, the present invention also provides the earphone insert state detection method of described mobile terminal, please refer to Fig. 2 and Fig. 3, said method comprising the steps of:
Step S10, central processing unit detect the first voltage of the first detection pin and the second voltage of the second detection pin in real time, and judge that whether described first voltage and/or the second voltage are lower than a reservation threshold.
In the present embodiment, the mode that mobile terminal adopts two-way to detect judges the left and right ear insert state of earphone.By power module 60, first bleeder circuit 30 and the second bleeder circuit 40 are powered.The high level produced through the first bleeder circuit 30 is loaded on the first detection pin D1, namely produces the first voltage of a high level.The high level produced through the second bleeder circuit 40 is loaded on the second detection pin D2, namely produces the second voltage of a high level.When earphone does not insert, earphone socket the 1st pin and the 2nd pin unsettled, the first voltage and the second voltage keep high level.Because the left ear 701 of earphone and auris dextra 702(are also left horn and right horn) impedance be 16 ohm or 32 ohm, much smaller than the equiva lent impedance of the first bleeder circuit 30 and the second bleeder circuit 40, as shown in Figure 2, when earphone insert and the left ear 701 of earphone and auris dextra 702 function normal time, high voltage on earphone socket the 1st pin be connected with left ear 701 is pulled down to ground, and namely the first voltage is converted to low level by high level; The second voltage in like manner on earphone socket the 2nd pin is also converted to low level.Correspondingly can arrange reservation threshold is 0.7V, judges that whether pressure value that the first the first voltage and second detecting pin D1 detects second voltage of pin D2 is converted to by high level the low level, i.e. the identifiable design earphone that are less than 0.7V and whether inserts and whether the function of the left ear 701 of earphone and auris dextra 702 is normal like this by the central processing unit of mobile terminal.
Step S20, when judging described first voltage and/or the second voltage lower than described reservation threshold, show corresponding judged result, and the voice signal received by mobile terminal is play by earphone.
Pressure value based on the first voltage and/or the second voltage has 3 kinds of combinations, and described step S20 specifically comprises following 3 kinds of situations:
1, when judging that described first voltage is lower than described reservation threshold, and when described second voltage exceedes reservation threshold, display judged result is earphone auris dextra fault, and the voice signal that mobile terminal receives is play by left ear.
In this step, the first voltage transitions is low level, and the second voltage keeps high level, shows that the link in the left ear 701 of earphone is normal, the high level on earphone socket the 1st pin can be dragged down; But the link in auris dextra 702 is abnormal, may disconnect, therefore earphone socket the 2nd pin can not be connected to ground, then keeps high level.By judged result---earphone auris dextra malfunction coefficient is on the display screen of mobile terminal, the left ear of reminding user can use, auris dextra can not use, the voice signal that mobile terminal receives transfers to left ear 701 through L channel L and plays, voice signal exports through R channel R, because auris dextra 702 fault sound cannot broadcast.
2, when judging that described first voltage exceedes described reservation threshold, and described second voltage lower than reservation threshold time, display judged result be the left ear fault of earphone, the voice signal that mobile terminal receives is play by auris dextra.
In this step, the first voltage keeps high level, and the second voltage transitions is low level, and the link showing in the left ear 701 of earphone may disconnect and cause earphone socket the 1st pin to be connected to ground, but the link in auris dextra 702 normally makes the second voltage be dragged down.By judged result---the left ear malfunction coefficient of earphone is on the display screen of mobile terminal, and the left ear of reminding user can not use, and auris dextra can normally use.The voice signal that mobile terminal receives cannot be play at left ear 701, and voice signal broadcasts in auris dextra 702.
When 3, judging described first voltage and the second voltage all lower than described reservation threshold, display judged result is that earphone inserts normally, and the voice signal that mobile terminal receives is play by the left and right ear of earphone.
In this step, because the first voltage and the second voltage are all changed in order to low level, show that the link in the left ear 701 of earphone and auris dextra 702 is normal, earphone socket the 1st pin and the 2nd pin thereof are connected to ground, by judged result---earphone inserts and is normally presented on the display screen of mobile terminal, reminding user earphone can normally use, and the voice signal that mobile terminal receives is transferred to left ear 701 from L channel L respectively, is transferred to auris dextra 702 carries out audio frequency broadcast from R channel R.User can receive calls, listens to the music or listen to the radio programme.User can be made to know the left ear of earphone and the service condition of auris dextra by above-mentioned judgement.
Step S30, when judging that described first voltage and the second voltage exceed described reservation threshold simultaneously, central processing unit controls mobile terminal and does not respond, and enquiry module controls central processing unit starting state query pattern according to the operational order of user.Please refer to Fig. 4, this step specifically comprises;
S301, when judging that described first voltage and the second voltage exceed reservation threshold simultaneously, judge whether earphone inserts.Earphone does not insert or earphone inserts and its left and right ear all damages the first voltage and the second voltage all may be caused simultaneously to exceed described reservation threshold.The two kinds of situations needing point earphone to insert or not insert operate respectively accordingly.
S302, when earphone does not insert, central processing unit control mobile terminal do not respond.If earphone does not insert, earphone socket the 1st pin and all unsettled the first voltage and the second voltage of making of the 2nd pin thereof keep high level.Now determine do not have plugged earphone, mobile terminal, without the need to response, keeps current operating state.
S303, when earphone inserts, central processing unit control mobile terminal do not respond; Enquiry module controls central processing unit starting state query pattern according to the operational order of user, judges the matching status of earphone and mobile terminal and show judged result.
If earphone inserts but the first voltage of detecting of central processing unit and the second voltage are high level, illustrate that earphone may break down or the correlation module fault of mobile terminal.The operational order that now need be inputted by user carrys out starting state query pattern, judges the matching status of earphone and mobile terminal further, namely determines the problem of earphone or the problem of mobile terminal; Please refer to Fig. 5, this step specifically comprises:
Step S3031, control central processing unit starting state query pattern by clicking enquiry module, its coordinate parameters on the display screen of mobile terminal is transferred to central processing unit by enquiry module.
For the mobile terminal of touch-screen class, after user's plugged earphone, mobile terminal is without any response, can point touching screen on enquiry module, enquiry module communicates with central processing unit, makes central processing unit starting state query pattern.This enquiry module is arranged on optional position or the fixed position of display interface, and it has corresponding coordinate parameters, namely the icon of this enquiry module coordinate on the touchscreen.This coordinate parameters is transferred to central processing unit by enquiry module.
Step S3032, receive described coordinate parameters when central processing unit, and when judging that current first voltage and the second voltage exceed reservation threshold, display judged result is earphone fault.
Described coordinate parameters is equivalent to a control command, after central processing unit receives coordinate parameters, central processing unit can be controlled again detect the first detection pin and second and detect voltage on pin, when judging the magnitude of voltage of current first voltage and the second voltage still as high level, display judged result is earphone fault, and the left and right ear of prompting user earphone all damages.Judge that the non-serviceable condition of earphone fault is that central processing unit receives coordinate parameters and detects that the first voltage and the second voltage are high level.In the specific implementation, enquiry module 50 can also be used for the multiple confirmation of other earphone using state.Other earphone using state comprises: left ear can use but auris dextra can not use, and left ear can not use but auris dextra can normally use, and earphone can normally use.
