Referring to Fig. 2, the step of the method for the vibration optimization of another embodiment of the present invention, including：
Step 21, it is caused when obtaining the mobile terminal sounding to shake when the mobile terminal is in beep pattern
Move the first strong and weak measurement parameter.
Specifically, during mobile terminal sounding, vibration strong or weak caused by mobile terminal can use displacement, speed and acceleration
The parameter characterizations such as degree.Preferably, the measurement parameter is acceleration.
In the embodiment, using the acceleration transducer of mobile terminal as vibrating sensor, collection mobile terminal, which produces, to shake
Acceleration magnitude (the change speed of vibration velocity) during vibration when dynamic characterize mobile terminal caused by vibration strong or weak, that is, represent

In the embodiment, during the audio signal generated when determining the mobile terminal sounding according to voice data, detection
Whether the mobile terminal is in noise scenarios；If mobile terminal is in noise scenarios, extract described in the voice data
The audio signal generated during mobile terminal sounding.
Specifically, when the mobile terminal is in noise scenarios, the voice data includes the mobile terminal sounding
Noise signal in Shi Shengcheng audio signal and the mobile terminal local environment；Wherein described noise signal is the audio
All audio frequency signal in addition to the audio signal generated in data when mobile terminal sounding.Detect in the voice data whether
Include noise signal；When including the noise signal in the voice data, the voice data is carried out at parsing

After interior part is decayed, ensure to the inhibition level of audio signal strength (sound intensity during mobile terminal sounding) compared with
In the case of small, being optimal of oscillation intensity caused by mobile terminal is suppressed.
If being unsatisfactory for formula (1), according to predetermined decay intensity step-length order incremented by successively, with more than the first filtering
The part that second wave filter of decay intensity corresponding to device is in the audio signal in default low-frequency range is filtered place
Reason, until meet the condition of formula (1), so as to ensure it is less to the inhibition level of audio signal strength in the case of, to movement
Being optimal of oscillation intensity caused by terminal suppresses.
As another implementation, when first measurement parameter is more than predetermined threshold value, according to predetermined frequency steps
It is long, the low frequency model of the part in the audio signal for being stepped up generating during the mobile terminal sounding in default low-frequency range
Enclose, until the ratio between the variable quantity of first measurement parameter and the variable quantity of the second measurement parameter is less than preset ratio threshold
Value.

After reason, sound when the first measurement parameter of caused vibration strong or weak is A2 and mobile terminal sounding during mobile terminal sounding
Second measurement parameter of loudness is B2.
If detecting the ratio between the variable quantity of the first measurement parameter and the variable quantity of the second measurement parameter, meet formula
(1), then it represents that after decaying to the part in the audio signal that is generated during mobile terminal sounding in default low-frequency range,
In the case of guarantee is less to the inhibition level of audio signal strength, oscillation intensity caused by mobile terminal is optimal
Change and suppress.
If detecting the ratio between the variable quantity of the first measurement parameter and the variable quantity of the second measurement parameter, public affairs are unsatisfactory for
Formula (1), then according to predetermined frequency step, increase in the audio signal in the low frequency model for presetting the part in low-frequency range
Enclose, and using predetermined decay intensity wave filter to being in after adjusting step in the audio signal that is generated during mobile terminal sounding
Part in default low-frequency range is (such as：Less than 820Hz) attenuation processing is carried out, until meeting the condition of formula (1), so as to ensure
In the case of less to the inhibition level of audio signal strength, being optimal of oscillation intensity caused by mobile terminal is pressed down
