If 202, terminal detects that the voice signal of main Mike's input is abnormal, one secondary Mike is arranged as main wheat terminal
Gram, words are sent in order to carry out voice by the main Mike after setting.
Wherein, when terminal detects the voice signal i.e. main Mike's exception of exception of main Mike's input, specified main Mike
It may damage, voice cannot have been carried out again and send words, a secondary Mike can be arranged at this time as main Mike, in order to pass through setting
Main Mike afterwards carries out voice and send words, to guarantee that terminal can be normally carried out voice communication.
In addition, Mike's switching method provided in an embodiment of the present invention is also applied for scene when terminal is recorded.
Specifically, whether the voice signal that can detecte main Mike's input in more Mikes is abnormal, if terminal is examined when terminal is recorded
The voice signal for measuring main Mike input is abnormal, then one secondary Mike is arranged as main Mike terminal, after through setting
Main Mike records, when main Mike occurs abnormal in more Mikes so as to solve the prior art, terminal cannot normally into
The problem of row recording.Unlike progress voice communication, when being recorded by main Mike, secondary Mike can not work, number
Word signal processor DSP does not need to carry out noise reduction process to the signal of typing yet, that is to say, that if terminal detects that main Mike is defeated
The voice signal that enters is abnormal, then terminal one idle Mike can be arranged as main Mike, in order to pass through the main Mike after setting
It records.
The embodiment of the present invention provides a kind of Mike's switching method, when the voice signal for detecting main Mike's input in more Mikes

When the method that embodiment provides is able to solve main Mike's appearance exception in more Mikes of the prior art, terminal cannot proceed normally language
The problem of sound is conversed.
The embodiment of the present invention provides a kind of Mike's switching method, is used for more Mike's terminals, which includes that Mike's routing is opened
It closes, and the input terminal of Mike's routing switch is connect with more Mikes, and the output end of Mike's routing switch is defeated with coder Codec's
Enter end connection, referring to Fig. 3, mainly may comprise steps of:
301, whether the voltage for the voice signal that terminal detects main Mike's input by Mike's routing switch is abnormal.
In this step, terminal can pass through Mike before the voice signal that main Mike inputs is by coder Codec
Whether the voltage that routing switch detects the voice signal of main Mike's input is abnormal.
Illustratively, comparator can be set in Mike's routing switch, detects the electricity of the voice signal of main Mike's input
Whether pressure is abnormal.Specifically, main Mike can not typing voice letter when leading to main Mike's exception due to main Mike damage etc.
Number, the signal of the main Mike input detected at this time may be the noise of circuit, due to the usually smaller example of the amplitude of circuit noise
Such as less than 10mV, it is believed that main Mike is without input signal, i.e., the voice signal of main Mike's input is abnormal, and otherwise, main Mike is just
The voice signal of typing should be the voice signal of user and being superimposed for ambient noise when often.Therefore, it is possible to by the one of comparator
End is set as the constant voltage of 10mV, the other end is connect with the voice signal that main Mike inputs, if main Mike in specified time
The voltage magnitude of the voice signal of input is less than 10mV, it may be considered that main Mike's no signal inputs, the voice of main Mike's input
The electric voltage exception of signal.Illustratively, which can be 1 minute.
Simultaneously as the voltage magnitude of ambient noise is generally higher than 10mV, thus can also be by Mike's routing switch
Comparator come comparison secondary Mike input voice signal whether be less than 10mV, if the voltage magnitude of ambient noise is small in secondary Mike
In 10mV, it may be considered that the input of secondary Mike no signal, the electric voltage exception of the voice signal of secondary Mike input, the i.e. secondary Mike are different
Normal cisco unity malfunction.
In addition it is also possible to Mike's routing switch be designed by other hardware circuits, to detect the language of main Mike's input
Whether the voltage of sound signal is abnormal, and the embodiment of the present invention is without limitation.
It should be noted that terminal can once examine the voice signal of main Mike input when being conversed every time
It surveys；Main Mike occurs abnormal in communication process in order to prevent, and terminal can also periodically believe the voice of main Mike input
It number is detected, such as can be primary every detection in 10 minutes, here without limitation.
If 302, electric voltage exception, terminal determines that the voice signal of main Mike's input is abnormal.
If in step 301, Mike's routing switch detects the electric voltage exception of the voice signal of main Mike's input, then can be true
The voice signal of fixed main Mike's input is abnormal, may thereby determine that main Mike is abnormal.
It should be noted that terminal can also be set before the voice signal that main Mike inputs is by coder Codec
Processing unit is set, spectrum analysis is carried out to the voice signal of main Mike input, if the frequency spectrum of the voice signal of main Mike input is not
In user voice signal spectral range (such as voice spectrum range is generally 80Hz~12kHz), then main Mike can be determined
The voice signal of input is abnormal；Or the processing unit can also determine the language of main Mike's input by way of speech recognition
Whether sound signal is abnormal.Whether the embodiment of the present invention is abnormal to the voice signal for specifically how detecting main Mike's input not to limit
It is fixed.
303, terminal passes through Mike's routing switch for the output port and coder of the main Mike of voice signal exception
Input port corresponding with main Mike disconnects in Codec, and selectes secondary Mike according to preset Mike's sequence, by what is selected
Input port connection corresponding with main Mike in the output port and coder Codec of secondary Mike.
When terminal determines the voice signal exception, i.e. main Mike's exception of main Mike's input in step 302, main Mike may
It has been damaged that, voice cannot be carried out again and send words.At this point, terminal can be by Mike's routing switch by the main wheat of voice signal exception
Gram output port and coder Codec in input port corresponding with main Mike disconnect, and according to preset Mike
Sequence selectes secondary Mike, by input terminal corresponding with main Mike in the output port and coder Codec of selected secondary Mike
Mouth connection, thus the main Mike that setting is new.Wherein, the process schematic of the new main Mike of Mike's routing switch setting may refer to
Fig. 4.In the output port and coder Codec for the secondary Mike that will be selected after input port connection corresponding with main Mike,
The secondary Mike is set as main Mike, can carry out voice by the new main Mike after setting at this time and send words, to guarantee to use
Family can be normally carried out voice communication.
Select secondary Mike according to preset Mike sequence during, currently to be selected if being detected in step 301
It, then can be according to the preset selected sequence of Mike's sequence when electric voltage exception, that is, secondary Mike exception of the voice signal of secondary Mike input
In come secondary Mike after current secondary Mike, and be set to new main Mike.
Illustratively, terminal can be right according to information such as the use habit of position and user of more Mikes in mobile phone
Preset Mike's sequence is configured, and preset Mike is sequentially written in memory.For example, if it is 1 that mobile phone, which has number, 2,
33 Mikes are located at positive bottom, front top and back side middle part, then No. 1, No. 2, No. 3 Mike's groups can be set
It closes, and according to the use habit of user, No. 1,2 can be set by the i.e. preset Mike's sequence of the main Mike preferentially used sequence
Number, No. 3 Mikes, i.e. No. 1 Mike is higher than No. 2 Mikes as the priority of main Mike, and No. 2 Mikes are high as the priority of main Mike
In No. 3 Mikes., can be using No. 1 Mike as main Mike when being conversed, No. 2 Mikes, No. 3 Mikes are as secondary Mike；When 1
When number Mike's exception, No. 2 Mikes can be arranged as main Mike according to preset Mike's sequence, No. 3 Mikes as secondary Mike, when
When No. 1 Mike restores normal, No. 1 Mike can be restored to be arranged as main Mike, No. 2 Mikes, No. 3 Mikes are secondary Mike；When No. 1
When Mike, No. 2 Mikes are abnormal, No. 3 Mikes can be arranged as main Mike according to preset Mike's sequence, at this point, due to No. 1
Mike, No. 2 Mikes are abnormal, thus it includes secondary Mike that terminal, which only includes main Mike not, and terminal carries out voice by main Mike and send
Words, but voice de-noising cannot be carried out by secondary Mike.It is of course also possible to by Mike's sequence in No. 1, No. 2, No. 3 Mike's combinations
It is set as No. 2, No. 1, No. 3 or No. 3, No. 2, No. 1 etc..
In addition, also can be set No. 1, No. 2 Mikes combine or No. 1, No. 3 Mikes' combinations or 1 if mobile phone includes 3 Mikes
Number Mike combination etc., at this point, do not include that some or certain several Mikes in Mike's combination of setting will not work, it is as not busy
Set Mike.The embodiment of the present invention combines with preset Mike's sequence without limitation the Mike being specifically arranged.
In addition, currently used main Mike can be highest priority in Mike's combination when starting to carry out voice communication
Mike, be also possible to the main Mike being arranged when last call.
It should be noted that the embodiment of the present invention is so that Mike's routing to be arranged between Mike and coder Codec and opens
It closes come what is be illustrated, which also can integrate inside coder Codec, and the embodiment of the present invention does not limit
It is fixed.
Certainly, Mike's switching method provided in an embodiment of the present invention is also applied for scene when terminal is recorded.
Specifically, when terminal is recorded, the voltage that the voice signal of main Mike's input can be detected by Mike's routing switch is
No exception, if electric voltage exception, terminal determines that the voice signal of main Mike's input is abnormal, at this point, terminal is opened by Mike's routing
It closes and disconnects input port corresponding with main Mike in the output port and coder Codec of the main Mike of voice signal exception
Connection, and secondary Mike is selected according to preset Mike's sequence, it will be in the output port and coder Codec of selected secondary Mike
Input port corresponding with main Mike connects, when main Mike occurs abnormal in more Mikes so as to solve the prior art, eventually
The problem of end cannot proceed normally recording.Unlike progress voice communication, the secondary Mike when being recorded by main Mike
It can not work, digital signal processor DSP does not need to carry out noise reduction process to the signal of typing yet, that is to say, that if terminal
Detect that the voice signal of main Mike input is abnormal, then terminal one idle Mike can be arranged as main Mike, in order to pass through
Main Mike after setting records.
The embodiment of the present invention provides a kind of Mike's switching method, when passing through wheat between more Mikes and coder Codec
Gram routing switch, when detecting the voice signal exception of main Mike's input in more Mikes, by the main Mike's of voice signal exception
Input port corresponding with main Mike disconnects in output port and coder Codec, then suitable according to preset Mike
Sequence selectes secondary Mike, by input port corresponding with main Mike in the output port and coder Codec of selected secondary Mike
Connection can carry out voice by the main Mike after setting at this time and send words to set new main Mike for the secondary Mike, because
And when being able to solve that main Mike occurs abnormal in more Mikes of the prior art, the problem of terminal cannot proceed normally voice communication.
The embodiment of the present invention provides a kind of Mike's switching method and mainly may comprise steps of referring to Fig. 5:
501, whether the voltage for the voice signal that terminal detects main Mike's input by digital signal processor DSP is abnormal.
In this step, terminal can pass through number after the voice signal that main Mike inputs is by coder Codec
Whether the voltage that signal processor DSP detects the voice signal of main Mike's input is abnormal.Due to by coder Codec it
Afterwards, the analog voice signal of Mike's input has been converted to digital signal.When main Mike damage etc. due to lead to main wheat
When gram exception, main Mike can not typing voice signal, at this point, the main Mike's input signal detected before coder Codec
It may be the noise of circuit.Illustratively, since the noise signal voltage magnitude of circuit is smaller, turn by coder Codec
Changing into after digital signal is constant low level (if inverted processing may also be constant high level), thus can consider master
For Mike without input signal, i.e., the voice signal of main Mike's input is abnormal.When main Mike is normal, the voice signal of typing should be
The voice signal of user is superimposed with ambient noise, and the signal after coder Codec analog-to-digital conversion should be height electricity
The digital signal at flat interval.Therefore, it is possible to detect the electricity of the voice signal of main Mike's input by digital signal processor DSP
Whether pressure is constant voltage, if then may determine that the voice signal electric voltage exception of main Mike's input.Similarly, when secondary Mike exception
When, it is also possible to the voltage for the voice signal for causing secondary Mike to input is steady state value, thus, secondary wheat can also be detected by this method
Whether the voltage of the voice signal of gram input is abnormal.
It is of course also possible to whether the voltage that the voice signal of main Mike's input is detected by other methods is abnormal, such as
Whether the voltage by detecting the voice signal of main Mike's input is more than a certain threshold value, if being specified more than this in specified time
Threshold value, it may be considered that the electric voltage exception of the voice signal of main Mike input, the embodiment of the present invention are detected to using which kind of mode
Whether the voltage of the voice signal of main Mike's input is abnormal without limitation.
It should be noted that one-time detection can be carried out to the voice signal of main Mike input when being conversed every time,
Periodically the voice signal of main Mike input can also be detected, such as can be primary every detection in 10 minutes, here
Without limitation.
If 502, electric voltage exception, terminal determines that the input signal of main Mike is abnormal.
If in step 501, digital signal processor DSP detects the electric voltage exception of the voice signal of main Mike's input, then
It can determine that the voice signal of main Mike's input is abnormal, may thereby determine that main Mike is abnormal.
It should be noted that digital signal processor DSP can also carry out frequency spectrum point to the voice signal that main Mike inputs
Analysis, if the frequency spectrum of the voice signal of main Mike input (such as voice spectrum range one not in user voice signal spectral range
As be 80Hz~12kHz), then can determine that main Mike's input signal is abnormal, so that it is determined that whether main Mike abnormal.The present invention is real
It is whether abnormal to the voice signal for specifically how detecting main Mike's input without limitation to apply example.
503, terminal selectes secondary Mike according to preset Mike's sequence by digital signal processor DSP, and then controls choosing
Fixed secondary Mike carries out voice by coder Codec as main Mike and send words.
When terminal determines the voice signal exception, i.e. main Mike's exception of main Mike's input in step 502, main Mike may
It has been damaged that, voice cannot be carried out again and send words.At this point it is possible to by digital signal processor DSP according to preset Mike's sequence
Secondary Mike is selected, and then controls selected secondary Mike as main Mike and send words by coder Codec progress voice.Specifically
, digital signal processor DSP can be by output port corresponding with the main Mike of voice signal exception in coder Codec
It is disconnected with input port corresponding with the main Mike of voice signal exception in digital signal processor DSP, and according to default
Mike's sequence select secondary Mike, by coder Codec with the corresponding output port of secondary Mike and digital signal selected
Input port connection corresponding with main Mike in processor DSP, thus the main Mike that setting is new.Wherein, digital signal processor
The process schematic of the new main Mike of DSP setting may refer to Fig. 6.It, can be with after the secondary Mike that will be selected is arranged as main Mike
