Specific embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Each implementation method of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In implementation method, in order that reader more fully understands the application and proposes many ins and outs.But, even if without these skills
Art details and many variations based on following implementation method and modification, it is also possible to realize the application technical side required for protection
Case.
First embodiment of the present utility model is related to a kind of mobile terminal.
As shown in figure 1, in present embodiment, the mobile terminal includes：Processor, audio, the first speed-sensitive switch and USB connect
Mouthful.
Specifically, processor can be connected with the detection pin ID of the USB interface, and according to the change of signal come judge access
The type of the earphone of USB interface.In present embodiment, processor can be by a GPIO interface (GPIO3 i.e. in figure) and detection
Pin ID is connected, and detection pin ID can be grounded by a big resistance (resistance is more than 10k ohm).
The speed-sensitive switch has：Selection end, common port, the first output end and the second output end.Wherein, selection end can control
Common port is in same time and an output end conducting.Specifically, (selection end can to select end, common port to be connected with processor
It is connected with a GPIO interface of processor, i.e. GPIO1 in figure)；First output end is connected with audio, audio and USB interface
Differential signal pin DP (D+) and DM (D-) connection；Second output end also connects with the differential signal pin DP and DM of USB interface
Connect.
When the earphone for accessing USB interface is digital earphone, processor can control the choosing of the first speed-sensitive switch by GPIO1
End is selected, its selection common port and the second output end is turned on.Now, processor can send to the common port of the first speed-sensitive switch
Data signal, the data signal is exported to the differential signal pin DP and DM of USB interface by the second output end, is accessed the USB and is connect
The digital earphone of mouth can receive the data signal.
When the earphone for accessing USB interface is for simulation earphone, processor can control the choosing of the first speed-sensitive switch by GPIO1
End is selected, its selection common port and the first output end is turned on.Now, processor sends numeral to the common port of the first speed-sensitive switch
Signal, the data signal is exported to audio by the first output end；Audio when the data signal from the first output end is received,
The data signal is converted into analog signal, and the analog signal of the conversion is sent to the differential signal pin DP of USB interface
And DM, the analog signal is received by the simulation earphone for accessing the USB interface.
It is noted that in present embodiment, processor is also connected with audio, and sends control signal to audio, with
The working condition of audio, such as control audio is controlled to turn the data signal when the data signal from the first output end is received
It is changed to analog signal.
Additionally, in present embodiment, the second speed-sensitive switch also can be set, make the second output of audio and the first speed-sensitive switch
End is connected by second speed-sensitive switch with the differential signal pin DP and DM of USB interface.Meanwhile, can also make processor and be somebody's turn to do
Second speed-sensitive switch connects (the second speed-sensitive switch can be connected with a GPIO interface of processor, i.e. GPIO2 in figure), to control
The data signal of the second speed-sensitive switch and the output switching of analog signal.
Specifically, when the earphone for accessing USB interface is for digital earphone, processor can be opened the second high speed by GPIO2
Concern is changed to data signal output mode, and the second speed-sensitive switch can be by the numeral of the second output end from the first speed-sensitive switch
Signal output to USB interface differential signal pin DP and DM.When the earphone for accessing USB interface is for simulation earphone, processor
Second speed-sensitive switch can be switched to by analog signal output pattern by GPIO2, the second speed-sensitive switch can be by from audio
Analog signal output to USB interface differential signal pin DP and DM.It is seen that, the setting of the second speed-sensitive switch is conducive to
The isolation of data signal and analog signal, prevents both from interfering.
Present embodiment, numeral, mould are carried out at cell phone mainboard end by the GPIO interface (GPIO3 i.e. in figure) of processor
Intend earphone identification, and path switching, earphone are carried out by two analog switches (i.e. the first speed-sensitive switch and the second speed-sensitive switch)
End then only needs to pass through big resistance eutral grounding on corresponding USB ID pin, you can a kind of adaptive hardware compatibility scheme of realization
(i.e. according to the headset type for accessing, selecting output digit signals or analog signal), while meeting numeral, two kinds of users of simulation
The need for colony, help to lift the experience of user.
The second embodiment of present embodiment is related to a kind of mobile terminal.Second embodiment is in first embodiment
On the basis of the further improvement done, mainly the improvement is that：Second embodiment further limits the first speed-sensitive switch, has
Beneficial to the operability of further lifting present embodiment.
