Step 203: in the case where receiving the described first instruction, identifying first voice signal and the rising tone
The volume difference of sound signal.
In the embodiment of the present invention, in the case where receiving the first instruction, it is believed that user is desired with of the invention real
The interaction flow of example is applied, therefore can further identify that the volume of first voice signal and the second sound signal is poor
Value.
Preferably, the volume difference of identification first voice signal and the second sound signal, comprising:
Sub-step A1 (not shown): first voice signal and the second sound signal are demodulated into digital letter
Number.
In the embodiment of the present invention, the first voice signal of the first microphone acquisition and the second sound of second microphone acquisition
Signal is usually analog signal, can by DSP (Digital Signal Processing, Digital Signal Processing) module etc.,
First voice signal and second sound signal are demodulated into digital signal, so that after the first voice signal and demodulation after demodulation
Second sound signal can be by the further analytical calculation of controller.
Sub-step A2 (not shown): defeated according to the first voice signal after demodulation and the second sound signal after demodulation
The volume difference out.
In the embodiment of the present invention, it can will be asked according to the first voice signal after demodulation and the second sound signal after demodulation
After difference, volume difference is obtained；The size of volume difference can be fed back strong between the first voice signal and second sound signal out
Weak relationship；Exemplary, after the first voice signal after demodulation can be subtracted to demodulation second sound signal, it is poor to obtain volume
Value illustrates that the first voice signal is better than second sound signal, volume difference is bigger, illustrates first if then volume difference is positive value
It is more that voice signal is better than second sound signal；If volume difference is negative value, illustrate that second sound signal is better than the first sound letter
Number, negative value is smaller, and to illustrate that second sound signal is better than the first voice signal more.
In concrete application, optionally, volume difference is amplified, output difference signal, because differential signal is poor greater than volume

Aobvious difference condition.
It, can be according to the volume after obtaining volume difference in a kind of optional embodiment of the embodiment of the present invention
Difference and preset signals threshold value, it is determined whether receive predetermined registration operation.
In the embodiment of the present invention, according to the comparable situation of volume difference and preset signals threshold value, analyse whether to receive pre-
If operation.In concrete application, predetermined registration operation can be is struck near any one of the first microphone or second microphone
It hits, or issues and operated compared with loud noise etc., so that the first microphone and second microphone voice signal collected have biggish area
Point, when volume difference is greater than default positive signal threshold value or is less than preset negative signal threshold value, can think to have received default
Operation；Be appreciated that if volume difference is between preset negative signal threshold value and default positive signal threshold value, it may be said that bright first
Microphone and second microphone voice signal collected do not have significant difference, it may be considered that being not received by predetermined registration operation.
In practical applications, user is a kind of easy to operate, identification by tapping the operation of mobile terminal and interacting
High touch control operation can more accurately judge to use along with the shake of mobile terminal in hammer action according to the shake
Whether family will interact with mobile terminal, therefore, pass through the record of acquisition the target jitter signal and step 205 of step 204
Acquisition time and etc. after, it is described according to the volume difference and preset signals threshold value, it is determined whether to receive predetermined registration operation
Step may include step 206, specifically:
Step 204: acquisition target jitter signal.
In the embodiment of the present invention, by taking user wishes to interact by the operation for tapping mobile terminal as an example, it is contemplated that if
First microphone or second microphone collect percussion sound, but the percussion is not for the first microphone or second microphone
, then it may generate erroneous judgement.Therefore, target jitter signal is acquired, and using target jitter signal as subsequent judgement interaction
One of condition can promote interactive accuracy.
In concrete application, target jitter signal, which can be, taps the corresponding dither signal of mobile terminal, specifically, taps
Mobile terminal from mobile terminal, smoothly movement can generate different dither signals, hammer action would generally be trembled with spike
It is dynamic, therefore be acquired the spiky jitter as target jitter signal.
The acceleration detection module in mobile terminal, such as gyroscope acquisition target jitter letter can be passed through in concrete application
Number, the embodiment of the present invention is not construed as limiting the specific equipment of acquisition target jitter signal.
Step 205: recording shake acquisition moment and first voice signal and described of the target jitter signal
The sound collection moment of second sound signal.
In the embodiment of the present invention, the shake acquisition moment for collecting target jitter signal can recorde, and collect first
Then the sound collection moment of voice signal and second sound signal can further analyze dynamic acquisition moment and sound collection
Whether the moment synchronizes, if synchronous it can be said that bright microphone is tapped, if asynchronous it can be said that bright microphone is not affected by and strikes
It hits, when microphone does not receive tapping operation, it is believed that be not received by predetermined registration operation.To avoid generating class due to the external world
Like spike waveform sound close to a certain microphone when generate erroneous judgement, to greatly increase identification accuracy.
Step 206: according to the volume difference and preset signals threshold value and shake acquisition moment and the sound
Acquire the moment, it is determined whether receive predetermined registration operation.
The embodiment of the present invention one kind in the specific implementation, the preset signals threshold value include: default first signal threshold value,
Default second signal threshold value；Default first signal threshold value is higher than the default second signal threshold value；
It is described that moment and the sound collection are acquired according to the volume difference and preset signals threshold value and the shake
Moment, it is determined whether receive predetermined registration operation, comprising:
In the case where the volume difference is higher than default first signal threshold value, determine that first microphone receives
First triggering；In the case where the volume difference is lower than the default second signal threshold value, determine that the second microphone is received
To the second triggering；There are first triggerings, and/or, in the case where second triggering, judge that the shake acquires the moment
Whether matched with the sound collection moment；Under shake acquisition moment and the sound collection moment matched situation,
Judgement receives predetermined registration operation.
In the embodiment of the present invention, when volume difference is higher than default first signal threshold value, illustrate that the first microphone receives the
One triggering, the first triggering specifically can be percussion triggering；When volume difference is lower than default second signal threshold value, illustrate the second Mike
Wind receives the second triggering, and the second triggering is specifically also possible to tap triggering；The first triggering is received in the first microphone, and/or, the
In the case that two microphones receive the second triggering, can further judge shake acquisition the moment and the sound collection moment whether
Match, if matching, illustrates the first microphone, or, second microphone receives tapping operation, mobile terminal receives predetermined registration operation.
It is exemplary, as shown in figure 3, showing when the first microphone is received and tapped three times, collected first sound of the first microphone
The corresponding situation of sound signal and the dither signal that acceleration detection module acquires.
It in the embodiment of the present invention, is designed using dual microphone, the hammer action according to user to a certain microphone, terminal pair
The voice signal that first microphone and second microphone receive amplifies processing, is judged by the threshold value of signal and time,
The synchronous signal jitter data plus acceleration transducer judge jointly, complete user's interaction, can not only eliminate external environment
Noise improves signal-to-noise ratio, due also to increasing the judgement of acceleration detection module, avoids caused by attacking or interfere because of simple sound
Misrecognition.
In actual use, a kind of exemplary mobile terminal structure is as shown in figure 4, the bottom end in mobile terminal is arranged first
Second microphone 20 (secondary microphone) is arranged in the top of microphone 10 (main microphon), mobile terminal, and user only needs to movement
The top of terminal or bottom, which tap, can recognize the corresponding push-button type of percussion, and operation is very simple, especially under special circumstances
Emergency application it is very effective, therefore can significant increase user experience.
Step 207: the number of the predetermined registration operation received within a preset time meets the case where the second preset condition
Under, determine target interactive instruction, and execute the target interactive instruction.
In the embodiment of the present invention, preset time can be determined according to actual application scenarios, exemplary, can be when will be default
Between be set as shorter time, such as 5 seconds, if user it is shorter it is interior issue multiple touch control operation, it may be considered that user needs
It interacts, thus may determine that target interactive instruction, and performance objective interactive instruction.
In concrete application, target interactive instruction and the second preset condition can have corresponding relationship, for example, the second default item
When part is 3, corresponding target interactive instruction is to dial predetermined telephone instruction, if then receiving 3 default behaviour within a preset time
Make, then can be confirmed and dial predetermined telephone instruction, and executes this and dial predetermined telephone instruction.It is understood that the second preset condition is
When 2, corresponding target interactive instruction can be screenshotss instruction etc..It is appreciated that the second preset condition and target interactive instruction
Corresponding relationship can be set by those skilled in the art according to practical application scene, for example, being set separately in preset time
Receive the corresponding target interactive instructions such as 1 predetermined registration operation, 4 predetermined registration operations, 5 predetermined registration operations, target interactive instruction
It can be set according to practical application scene, for example, adjusting volume, mute, alarm, one-touch easy dialing, snapshots, opening
The instruction such as recording is opened, the present invention is not especially limit this.
Below to determine target interactive instruction and performance objective friendship if receiving predetermined registration operation three times within a preset time
Mutually for instruction, illustrate the working principle of the exchange method of the embodiment of the present invention.
If according to the second sound signal of the first voice signal and the second microphone acquisition acquired to the first microphone, point
The predetermined registration operation for receiving and corresponding to second microphone three times is precipitated, specifically, predetermined registration operation can be tapping operation, the second wheat
The second sound signal of gram elegance collection will the first voice signal obviously than the acquisition of the first microphone it is strong, as shown in figure 5, right
There should be 3 of short duration spikes to occur in the sound collection schematic diagram of second microphone.It adapts to, the second preset condition and right
The target interactive instruction answered can be, and in the case where second microphone receives 3 predetermined registration operations, determine first object interaction
It instructs and executes first object interactive instruction.

In the embodiment of the present invention, when using tapping operation as predetermined registration operation, the voice data of percussion is similar to pulse, shorter
Time has the high-amplitude of moment to generate, and this point can distinguish other sound generated in a certain microphone, is preferably handed over
Mutual effect.
It is appreciated that if mobile terminal is because the reasons such as collision, noise collect voice signal, because the collision, making an uproar
Sound etc. is not usually to be directed to one of microphone, so the voice signal difference of the first microphone and second microphone acquisition
Less, as shown in fig. 7, the first microphone and second microphone can have 3 spikes to occur, corresponding differential signal is not yet
Greatly, then the conclusion for not receiving predetermined registration operation can be obtained by analyzing submodule, therefore not will cause the interaction of mistake.Therefore, of the invention
Embodiment can not only eliminate the interference of external environment noise, and the extraneous similar knock generated can also be avoided to make system erroneous judgement,
Exemplary, directly being thrown away the scene put with mobile terminal when mobile terminal a part is tapped can be distinguished, so as to
