During its specific implementation, as depicted in figs. 1 and 2, also be provided with the earphone interface 130 that is connected with described circuit board of mobile phone 110 on described mobile phone body 100 surfaces.And described circuit board of mobile phone 110 is provided with the earphone interface circuit 200 that is connected with described earphone interface 130.
As shown in Figure 2, described earphone interface circuit 200 comprises ground wire 206, right-channel signals line 201, left channel signals line 202 and the Mac circuit 210 that is connected with earphone interface 130 respectively.Described Mac circuit 210 comprises: the Mike's holding wire 203 (MIC+) that is connected with described earphone interface 130, first pin two 05 that is used for adding Mike's bias voltage that first resistance R 1 and second resistance R 2 by series connection is connected with described Mike's holding wire 203, and second pin two 09 that is used to detect Mike's signal voltage that is connected with described Mike's holding wire 203 by the 3rd resistance R 3 to described Mac circuit.And 204 be MIC-.
Below will do a step to the utility model by a concrete Application Example describes in detail:
Usually, mobile phone has following several talking mode: (1) does not use any earphone, the audio frequency output of using earpiece or loudspeaker to put outward, and mobile phone master Mike is as the talking mode of audio frequency input; (2) use band Mike's earphone to converse; (3) use band Mike's bluetooth earphone to converse (general bluetooth earphone all has Mike).
When the earphone of mobile phone does not form unified interface standard, each tame mobile-phone manufacturers can have the earphone interface definition of oneself to play and conversation with the MP3 that supports earphone, when people in order to pursue more high-quality music taste, hope is used on mobile phone in the high-quality earphone on computer and other stereo sets, and mobile phone will compatible become syllogic stereophone (not being with Mike) and these two kinds of earphones of four-part form stereophone (being with Mike) of mobile phone standard.
Like this, mobile phone of the present utility model has just increased the call mode of a kind of use syllogic stereophone (not with Mike), stereophone is as voice output, mobile phone master Mike is as voice output, when inserting earphone, whether judgement earphone band or not Mike, is set to different earphones and uses pattern, exports configuration if the conversation of band earphone starts corresponding phonetic entry.Convenient for users like this, mobile phone is many a kind of call mode.
In the mobile phone of the utility model embodiment the earphone interface circuit schematic diagram as shown in Figure 2, wherein 1 is earphone ground signalling line, 201 is right-channel signals line (Headset R channel), 202 is left channel signals line (Headset L channel); 210 is Mac circuit, and 203 is (MIC+) Mike holding wire, and 204 is MIC-.
As shown in Figure 2,209 is ADC_sendkey Mike line voltage signal test point, wherein, ADC_sendkey is used for cooperating earphone keystroke to realize that the voltage of receiving/hang-up telephony feature reads pin, is second pin two 09 that is used to detect Mike's signal voltage in the mobile phone base band chip.Need to use an ADC_sendkey pin two 09 to read level on Mike's holding wire in the utility model, distinguishing different headset types, can multiplexing above-mentioned ADC_sendkey pin, also can use other ADC_sendkey pins.
As shown in Figure 2, the 205th, first pin two 05 that adds Mike's bias voltage of mobile phone base band chip output, be used to Mac circuit 210 power supply, first pin two 05 of the described Mike's of adding bias voltage is that first resistance R 1 of 1K and second resistance R 2 that resistance is 1.5K are connected on Mike's holding wire 203 by resistance.130 is the earphone interface of the mobile device of the utility model embodiment, these two kinds of earphones of syllogic stereophone (not being with Mike) that can fit standard and four-part form stereophone (band Mike).As shown in Figure 3,10 for the syllogic of standard not with Mike's stereophone, the interface signal definition from left to right is followed successively by: L channel 11, R channel 12, ground 13.As shown in Figure 4,20 for being standard four-part form band Mike's stereophone, and the interface signal definition from left to right is successively: L channel 21, and R channel 22, Mike 23, ground 24.
Should be with in implementing, its principle in communication process comprises:
The first step with reference to Fig. 2, when earphone has inserted earphone interface 220 need conversations, reads the headset mode type of current insertion, and judges whether this earphone is with Mike.This conversation comprises incoming call conversation and outgoing call.
Whether be with Mike to carry out as follows judging this earphone:
1. with reference to Fig. 2, when mobile phone did not insert earphone, mobile phone base band chip can not exported first pin two 05 of MIC signal bias voltage (approximately 2V) to the described Mike's of adding bias voltage;
2. when mobile phone inserts earphone, the headset detection circuit of mobile device of the present utility model can produce a hardware interrupts, interrupt service routine can drive Mike's bias voltage that first pin two 05 of hardware by the described Mike's of adding bias voltage add 2V to Mac circuit 210, at this moment reads voltage on Mike's holding wire by second pin two 09 that is used to detect Mike's signal voltage and judges that this earphone band or not Mike;
3. if do not insert with Mike's earphone, because the earth signal GND on the syllogic headset plug can link to each other with the Mike's holding wire 203 on the earphone socket on the mobile phone, Mike's signal on the mobile phone is moved to low level, at this moment second pin two 09 that is used to detect Mike's signal voltage is read ground level less than 0.3V, when the magnitude of voltage on Mike's holding wire during less than 0.3V, be identified as the syllogic earphone of not being with Mike, and the prompting user selects syllogic earphone call mode by described toggle switch 120, promptly in current earphone for not with Mike's syllogic earphone the time, selecting the call voice output mode by described toggle switch is earphone horn output, and the phonetic entry pattern is mobile phone master Mike input.
4. if band Mike's four-part form earphone inserts, because the bias voltage of first pin two 05 of Mike's bias voltage is added on Mike's signal, second pin two 09 that is used to detect Mike's signal voltage will be read the high level greater than 1.5V; When the magnitude of voltage on Mike's holding wire during, be identified as the four-part form earphone of the earphone of current insertion, and the prompting user selects four-part form earphone call modes by described toggle switch 120 for band Mike greater than 1.5V.When promptly if current earphone is band Mike's four-part form earphone, can select the call voice output modes by described toggle switch 120 be earphone horn output, and the phonetic entry pattern is earphone Mike input.
Therefore, a kind of mobile device provided by the utility model, can discern the earphone band easily and or not Mike, make the user can use standard syllogic earphone to converse, promptly use the syllogic earphone to make receiver, use mobile phone master Mike as the input of conversation sound simultaneously, it makes mobile phone increase the new function of using standard syllogic earphone to converse, provides users with the convenient.Certainly the user also can directly select four-part form earphone call mode or syllogic earphone call mode by described toggle switch 120 according to the headset type that is inserted.
When the user when using the syllogic earphone to listen to the music, if the phone incoming call is arranged, use cellphone subscriber of the present utility model not need to pull out again earphone and just can proceed to converse, brought convenience to the user like this.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection range of the utility model claims.
