A kind of earphone identification call method and mobile phone based on mobile phone provided by the present invention are mainly distinguished different earphones by handset identity, and the user is provided the demand under different occasions.What detect insertion when mobile phone is mobile phone during with four signal pins earphones, and each function can normally be used; And when mobile phone detect insertion be three signal pins earphones the time, the user is in when conversation, the main microphone on the mobile phone open fuselage is for user's use, the user can also continue to use original earphone to listen to sound, and need aim at the main microphone on the mobile phone when giving orders or instructions.
For making purpose of the present invention, technical scheme and advantage clearer, clear and definite, below develop simultaneously with reference to accompanying drawing that the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
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, mobile phone will compatible become the earphone of three signal pins of mobile phone standard (not with Mike's syllogic stereophone, as shown in Figure 1) and the earphone of four signal pins (band Mike, these two kinds of earphones as shown in Figure 2).
As shown in Figures 2 and 3, be respectively the headset plug of standard four signal pins and the physical dimension figure of socket.Wherein, conductive ring and contact shell fragment be defined as respectively L (L channel), R (R channel), MIC (microphone), GND ().
In the headset plug of standard four signal pins shown in Figure 2: L (L channel) 101 is the plug tip of electric conducting material, 102 are the insulation ring set, R (R channel) 103 encircles electric conducting material in first, MIC (microphone) 104 encircles electric conducting material in second, GND () the 105 plug end ring sets for conduction, 106 is plug end hand grip part.Fig. 3 is the socket adaptive with the headset plug of Fig. 2,111 is the tip contact shell fragment of L (L channel), 113 be the R R channel first in ring contact shell fragment, 114 be MIC second in encircle the contact shell fragment, 115 be GND () end-rings contact shell fragment, 116 is the socket ring set.
After earphone inserted, the microphone of mobile phone input path switched to earphone MIC (microphone) from mobile phone.Earphone socket is standard 4 contacts, but the headset plug of 3.5MM is divided into two classes at present: the four-part form earphone that a class is described for Fig. 2.
An other class does not then have the earphone of three signal pins of MIC, as shown in Figure 1, wherein, 11 is L channel plug tip, 12 is the R channel conducting ring, and 13 is ground wire, can obviously find out from the earphone of four signal pins of the earphone of three signal pins of Fig. 1 and Fig. 2, the earphone of three signal pins is the same with the earphone total length of four signal pins, but the ground wire 115 of the earphone of its ground wire 13 to four signal pins of the earphone of three signal pins is long.
Two corresponding positions of conductive ring of the MIC of the earth connection 13 of three signal pins headset plugs (as shown in Figure 1) and four signal pins headset plugs (as shown in Figure 2) and GND are independent GND signal pins.This just means, when insert on the mobile phone be three signal pins earphones the time, the MIC signal pins of earphone socket has just linked to each other with the GND signal on the mobile phone, and the GND signal pins of earphone socket links to each other with ground on the mobile phone, be MIC signal and ground short circuit, level is low, and will close earphone MIC passage earlier in case leak-stopping this moment.
And when insert be four signal pins earphones the time, earphone MIC signal outside does not have and ground short circuit, and is moved to high level on the head circuit of mobile phone inside.So just can distinguish different earphones by the level on the MIC signal that detects earphone.
Promptly when the earphone of three signal pins inserts as shown in Figure 3 handset earphone plug, the MIC holding wire that makes mobile phone inside and GND () link to each other, make that the MIC holding wire is a low level.Use does not have the earphone of MIC, if according to normal flow process, after earphone inserts, the microphone input path of mobile phone will switch to GND (), converse by earphone this moment, then can only answer, and can not talk.Method of the present invention when earphone inserts, can be distinguished two kinds of headset plugs, can bring great convenience to the user, and is as described below.

So, among the present invention, preferably, adopt after earphone is confirmed to insert fully, open timer, adopting the N time is to detect an earphone MIC signal level every 150 milliseconds, and continuous three detections judge whether this microphone signal level is low level.Described low level is level closely, is less than or equal to 0.3V approximately.Be about to timer and be made as 150 milliseconds, the continuous like this three times low level time that detects is at least 300 milliseconds, the time of pressing greater than common button (is about 200 milliseconds through testing authentication repeatedly), so just avoided causing by hanging up on the earphone (or answering) key the unusual interference of level to a greater degree by mistake, and the possibility that the disconnected situation of the erroneous judgement that causes occurs.
Step S230, when continuous plural number time (once, preferably be three times) when detection microphone signal level is low level, the earphone of then judging current insertion is three signal pins earphones, open mobile phone master MIC passage during conversation, the microphone that switch mobile phone carries is imported as audio frequency, earphone is exported as audio frequency, and closes earphone MIC passage.
Step S240, when continuous plural number time (once, preferably be three times) when detection microphone signal level is not low level, the earphone of then judging current insertion is four signal pins earphones, open earphone MIC passage during conversation and send words, the microphone that adopts earphone to carry is imported as audio frequency, earphone is exported as audio frequency, and closes mobile phone master MIC passage.
Therefore, the embodiment of the invention based on the earphone of mobile phone identification call method, have following advantage, 1, this method is simple effectively practical, do not increase cost; When 2, the user uses three signal pins earphones, according to different application scenarios, the mode of operation that switch mobile phone is different.When only listening to the music, need not to open any MIC passage; During conversation, open that main MIC is user-friendly on the mobile phone.
