Description
Technical field
The invention belongs to the mobile communication equipment technical field, relate to a kind of mobile terminal, relate in particular to a kind of mobile terminal of simultaneously supporting 3 segmentation earphones and 4 segmentation earphones; Simultaneously, the invention still further relates to a kind of operation method of simultaneously supporting the mobile terminal of 3 segmentation earphones and 4 segmentation earphones.
Background technology
At present, the music walkman equipment such as MP3 and PC terminal are all supported 3 segmentation earphones, and mobile terminal is only supported 4 segmentation earphones.When everybody uses earphone, often encounter the situation that the mobile terminal mistake is used 3 segmentation earphones, the other side that causes making a phone call can not hear the sound of oneself or listen to the music the situations such as the switching song is abnormal.
The signal definition of 3 segmentation earphones is illustrated in fig. 1 shown below.The signal definition of 4 segmentation earphones commonly used has two kinds, shown in following Fig. 2 and Fig. 3.From Fig. 1, Fig. 2 and Fig. 3, the main distinction of 3 segmentation earphones and 4 segmentation earphones is:
(1) 3 segmentation earphone has 3 pins, and the position of pin one is the same with length with the position of 4 segmentation earphone pin ones and pin two with length.
(2) 4 segmentation earphones have between MIC signal and MIC, GND a mechanical switch, and 3 segmentation earphones do not have MIC signal and mechanical switch.
When with 4 segmentation earphones, being inserted into the common mobile terminal of only supporting 4 segmentation earphones, during conversation, because 4 segmentation earphones have the MIC signal, both sides can normally hear the other side's sound, when the user presses mechanical switch, MIC signal and GND conducting, it is low that system detects the MIC signal, with this, answers or hangs up the telephone; When listening to the music, the user presses by mechanical switch, MIC signal and GND conducting, and it is low that system detects the MIC signal, with this, switches song.
When with 3 segmentation earphones, being inserted into the common mobile terminal of only supporting 4 segmentation earphones, in the time of conversation, because 3 segmentation earphones do not have MIC, cause the other side to can't hear the sound of oneself.Because the position of 3 segmentation earphone pin ones is the same with length with the position of 4 segmentation earphone pin ones and pin two with length, the insertion of 3 segmentation earphones, cause mobile terminal side MIC signal and GND signal conduction, it is low that system detects the MIC signal, the meeting automatic call answering, and mobile terminal is at this time in headset mode.Equally, when listening to the music, the insertion of 3 segmentation earphones, cause mobile terminal side MIC signal and GND signal conduction, and it is low that system detects the MIC signal, and system can be switched song always, can't normally listen to the music.
In view of this, nowadays in the urgent need to designing a kind of new mobile terminal, in order to overcome the above-mentioned defect of existing mobile terminal.
