Description
Technical field
The present invention relates to field of communication technology, more particularly to a kind of detection method of earphone call.
Background technology
It is matched with terminal device in use, user may during earphone is extracted from terminal device in earphone
Will not all it extract moment, but since terminal device detects the signal of earphone extraction, and when triggering call hang-ups
During interrupt signal, the possible therefore kill-call of terminal device, but user misses sometimes when earphone not yet extracts terminal completely
Triggering terminal signal, so as to cause dropped calls.
The content of the invention
In view of the problems of the existing technology, a kind of detection method of earphone call is now provided.
Specific technical solution is as follows：
The detection method of a kind of earphone call a, there is provided earphone interface and inserted with the audio being adapted to the earphone interface
The terminal in hole, the detection method include：
Step S1, the earphone interface are entirely insertable in the audio jack, earphone interface circuit output first voltage, place
Manage device and control the earphone interface circuit conducting using the first voltage；
Step S2, establishes call, and the part earphone interface, the earphone interface circuit are extracted in the audio jack
Export second voltage；
Step S3, one trigger signal of output to the earphone interface circuit, the processor according to the trigger signal and
The second voltage exports an interrupt signal；
Step S4, abandons the interrupt signal to maintain to converse.
Preferably, the earphone interface includes call portion, and the grounding parts being connected with the call portion, connect with the grounding parts
The R channel connect, the L channel being connected with the R channel.
Preferably, the L channel is the part for being firstly inserted into the audio jack.
Preferably, the earphone interface of 3.5 millimeters of the earphone interface.
Preferably, it is the L channel and the R channel part earphone interface to be extracted in the audio jack.
Preferably, the step S3 includes：
Step S31, the trigger signal is exported according to the operation of the break key to earphone.
Preferably, the first voltage is 0.4-1.7V.
Preferably, the second voltage is more than or equal to 1.9V.
Preferably, in the step S3, when exporting the trigger signal to the earphone interface circuit, the earphone interface
Circuit output voltage is less than 0.4V.
Preferably, further included after the step S4：
Step S5, extracts all earphone interfaces, the earphone interface circuit output second in the audio jack
Voltage, the processor export the interrupt signal according to the second voltage；
Step S6, abandons the interrupt signal to maintain the call.
The beneficial effect of above-mentioned technical proposal is：
In above-mentioned technical proposal, if extract audio jack in earphone interface part, it can set to abandoning output
Interrupt signal so that it is invalid that the terminal signaling of output is judged as, so as to not interfere with what user extracted in earphone interface part
When call.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of the embodiment of the detection method of earphone call of the present invention.
Embodiment
It should be noted that in the case where there is no conflict, following technical proposals, can be mutually combined between technical characteristic.
The embodiment of the present invention is further described below in conjunction with the accompanying drawings：
Present embodiments provide a kind of detection method of earphone call, there is provided an earphone interface and with being fitted with earphone interface
The terminal for the audio jack matched somebody with somebody, as shown in Figure 1, detection method includes：
Step S1, earphone interface are entirely insertable in audio jack, and earphone interface circuit output first voltage, processor utilizes
First voltage control earphone interface circuit conducting；
Step S2, establishes call, and part earphone interface, the second electricity of earphone interface circuit output are extracted in audio jack
Pressure；
Step S3, one trigger signal of output to earphone interface circuit, processor are exported according to trigger signal and second voltage
One interrupt signal；
Step S4, abandons interrupt signal to maintain to converse.
In the present embodiment, earphone interface is entirely insertable among audio jack first, at this time in audio jack (Audio
Jack relative displacement is produced in), this relative displacement can cause the level change of earphone interface circuit again, export first voltage.
When audio jack is extracted in earphone interface part, earphone interface circuit output second voltage, and at this moment
If earphone exports trigger signal, processor can processor interrupt signal is exported according to trigger signal and second voltage, pass through
Software design patterns act so that interrupt signal is invalid, can normally keep conversing.
In a preferred embodiment of the invention, earphone interface includes call portion, the grounding parts being connected with call portion, with connecing
The R channel of ground portion connection, the L channel being connected with R channel.
In a preferred embodiment of the invention, L channel is the part for being firstly inserted into audio jack.
In a preferred embodiment of the invention, the earphone interface that 3.5 millimeter of earphone interface.
In a preferred embodiment of the invention, it is L channel and right sound to extract part earphone interface in audio jack
Road.
In a preferred embodiment of the invention, step S3 includes：
Step S31, trigger signal is exported according to the operation of the break key to earphone.
In a preferred embodiment of the invention, first voltage 0.4-1.7V.
In a preferred embodiment of the invention, second voltage is more than or equal to 1.9V.
In a preferred embodiment of the invention, in step S3, when exporting trigger signal to earphone interface circuit, earphone connects
Mouth circuit output voltage is less than 0.4V.
In a preferred embodiment of the invention, further included after step S4：
Step S5, extracts whole earphone interfaces, earphone interface circuit output second voltage, processor root in audio jack
Interrupt signal is exported according to second voltage；
Step S6, abandons interrupt signal to maintain to converse.
In above-described embodiment, since the ENIT-HEADSET pins in earphone interface circuit can be responsible for earphone insertion and pull out
Go out two states, the action hung up the telephone also needs to another signal pins i.e. ACCDET, real-time test earphone state；In earphone
When being not inserted into, ACCDET detects 1.9V (high level), and UI display interfaces do not show earphone icon, earphone path at this time
Also not transmission signal；Interrupt foot EINT-HEADSET after earphone is inserted into be triggered, while ACCDET detects that a scope is
The voltage of 0.4V-1.7V, earphone path, while UI interface display earphone icons can be opened by being followed by subsequent processing device (CPU)；And work as earphone
On hook be pressed after ACCDET will detect low level (0V), then CPU will initiate the action hung up the telephone.User makes
Wanting to extract earphone when being conversed with earphone, but only a hand is idle, then user singlehanded will slowly extract earphone,
The situation of " insertion portion " just occurs during this, (hook key signal transmission is drawn due to the HSMIC on audio jack at this time
Foot) and earphone on GND short circuits, CPU recognizes hook key and is pressed, and exports interrupt signal, is abandoned at this time by software design patterns
Interrupt signal instructs so that call maintains.
To sum up, in above-mentioned technical proposal, if extract audio jack in earphone interface part, can set defeated to abandoning
The interrupt signal gone out so that it is invalid that the terminal signaling of output is judged as, and is pulled out so as to not interfere with user in earphone interface part
Call when going out.
By explanation and attached drawing, the exemplary embodiments of the specific structure of embodiment are given, it is smart based on the present invention
God, can also make other conversions.Although foregoing invention proposes existing preferred embodiment, however, these contents are not intended as
Limitation.
For a person skilled in the art, after reading described above, various changes and modifications undoubtedly will be evident.
Therefore, appended claims should regard whole variations and modifications of the true intention and scope that cover the present invention as.Weighing
