Particularly, as shown in Figure 4, the method for the adjustment audio gain parameter of present embodiment comprises the steps:
Generally all be provided with a plurality of level of sound volume in each terminal, the purpose that level of sound volume is set is to be provided with the volume of the sound of control loudspeaker output, so the corresponding audio gain parameter of each level of sound volume, the relation between level of sound volume and the audio gain parameter can be stored in the terminal with the form of volume of reception table of grading.The user is when having selected a level of sound volume, and the audio gain parameter of current setting is exactly and this level of sound volume corresponding audio gain parameter.Utilize this audio gain parameter just can be to the described audio electrical signal processing and amplifying that gains.
Can utilize an acoustoelectric sensor to gather the sound of loud speaker output, this acoustoelectric sensor is arranged on the position near loud speaker, receives the sound that loud speaker broadcasts, and the volume of definite sound that receives.(MIC) is similar for the function of this acoustoelectric sensor and microphone, does not describe in detail at this.
In the embodiment of the invention, the corresponding volume reference value of level of sound volume that described default volume reference value is and sets, each level of sound volume can corresponding volume reference value, for example, the volume reference value of the first level of sound volume correspondence is 10db, and the volume reference value of the second level of sound volume correspondence is 20db.What store in the volume of reception table of grading at this moment, is corresponding relation between level of sound volume and audio gain parameter, the volume reference value.
This step is under a certain level of sound volume, collect the volume of the voice signal that loud speaker broadcasts after, the volume volume reference value corresponding with this level of sound volume of gathering compared.
In another embodiment of the present invention, this default volume reference value also can be a fixed reference, and irrelevant with level of sound volume.
Step 460 is adjusted the corresponding audio gain parameter according to comparative result.
In one embodiment of the invention, as shown in Figure 5, this step comprises:
For example, if current level of sound volume is the 2nd grade, corresponding volume reference value is 20db, if this moment, terminal received audio signal by network side from the conversation opposite end, after audio signal is converted to the voice signal broadcast from loud speaker, the volume that acoustoelectric sensor collects is 10db, volume reference value less than current volume grade correspondence, then can increase the gain of audio signal, be twice as the yield value that increases audio gain parameter being increased, make audio signal amplify the back volume and can reach 20db substantially through gain.Equally, the wave volume that collects when acoustoelectric sensor is 30db, greater than the volume reference value 20db of current volume grade correspondence, then needs to reduce the yield value of audio gain parameter, makes audio signal amplify the back volume through gain and still can reach 20db substantially.
If volume reference value be the fixed reference with the irrelevant acquiescence of level of sound volume, then no matter be in what level of sound volume at present, after adjust volume afterwards all will with the fixed reference basically identical of this acquiescence.
In one embodiment of the invention, this adjustment process can also be a real-time and dynamic, promptly in the sound playing process, execution in step 440-460 periodically: the volume to voice signal is gathered, compare with reference value, adjust according to comparative result, make the volume of voice signal be consistent substantially with reference value.

Whether step 610 judges the wave volume that detects greater than reference value, if, execution in step 620; If not, execution in step 630.
Step 620 by first adjusted value of setting, reduces described first adjusted value with the yield value of gain parameter.
After the adjustment, owing to be dynamically to adjust in real time,, and compare,, then current gain parameter value is reduced described first adjusted value again, until basic identical with reference value if at this moment still big than reference value with reference value so adjusted volume is still gathered.
Step 630 judges that whether the wave volume that detects is less than reference value.If, execution in step 640; If not, then flow process finishes.
Step 640 by second adjusted value of setting, increases described second adjusted value with the yield value of gain parameter.Through constantly adjusting, finally also can reach the essentially identical purpose of wave volume and reference value.
Described first adjusted value can be identical with second adjusted value, also can be different; Those of ordinary skill in the art as can be known, the granularity of adjustment is more little, promptly first adjusted value and second adjusted value are more little, then the precision of Tiao Zhenging is high more, but it is long more to adjust to the time that reference value needs.Can set suitable adjustment granularity according to actual needs.
In current level of sound volume is under the situation of other values, equally can be according to the current audio gain parameter of discrepancy adjustment of the wave volume of the gathering volume reference value corresponding with this grade.
