Product development stage determines adjustable gain range of the different balanced devices under different level of sound volume according to experimental result, alternatively,
Product service stage, by user's sets itself.
Here, a level of sound volume corresponds to the adjustable gain range of at least one balanced device in mapping table.For example, described can
Gain ranging is adjusted to include at least one of the following: the first adjustable gain range, the second adjustable gain range；It wherein, described first can
Adjust gain ranging for configuring the first balanced device, the second adjustable gain range is for configuring the second balanced device.
Step 202: being based on the level of sound volume, determine that the level of sound volume is corresponding adjustable from level of sound volume mapping table
Gain ranging；Wherein, the adjustable gain range of the level of sound volume mapping table Hi-Mid amount grade is no more than amount of bass grade

The second indication information is used to indicate that the intelligent equalization device is adjustable and the graphic equalizer is non-adjustable.
That is, when comprising multiple adjustable balanced devices, user can choose wherein 1 be adjusted.Figure is equal
Weighing apparatus and intelligent equalization device mutual exclusion configuration, i.e., one wherein be in adjustable state when, another is in non-adjustable state, is in
The balanced device of adjustable state can adjust system sound volume, and the balanced device in non-adjustable state can not adjust system sound volume.
Step 205: receiving the gain adjustment parameter that user inputs from the adjustment interface of the audio balanced device；
In practical application, this method further include: whether detection volume adjusting function is opened, if opening, judgement is GEQ effective
Or IEQ is effective, if GEQ is effective, it is disable, 40% opacity that IEQ, which is arranged,；If IEQ is effective, GEQ, which is arranged, is
Disable, 40% opacity；If detecting the operation that switches between IEQ and GEQ, keep original IEQ adjustment parameter or
GEQ adjustment parameter is constant.
Specifically, user is on adjustment interface after control display interface shows the adjustment interface of the audio balanced device
Gain adjustment parameter is set, for example, selecting " open, abundant or full " for intelligent equalization device as shown in Figure 3, as shown in Figure 4
Gain is arranged for different frequency by sliding slider for graphic equalizer.

In playing process, when user adjusts level of sound volume, the system that can trigger recalculates basic volume, according to calculating
To basic volume inquire mapping table again, to obtain corresponding GEQ gain ranging (or IEQ gain), and to configuration unit
Configuration-direct is sent, for configuring GEQ adjustable gain range (or IEQ gain).
In further embodiments, the preGain value of audio-frequency information can also be corresponded in mapping table including level of sound volume；Institute
The method of stating includes: to determine the preGain value of audio-frequency information when detecting volume adjustment event；It is determined based on the preGain value
Level of sound volume and adjustable gain range.
As shown in table 4, under Doby panorama sound system frame, different preGain values correspond to different level of sound volume and difference
Basic volume, current volume level and GEQ adjustable gain model can be determined according to the current preGain value of electronic equipment
It encloses and IEQ gain.
Table 4
It when playing sound, needs to calculate the preGain value of audio stream plays, is inquired according to the preGain value being calculated
Mapping table to obtain corresponding IEQ gain, and sends configuration-direct to configuration unit, and the IEQ for configuring target equalizer increases
Benefit.
In playing process, when user adjusts level of sound volume, the system that can trigger recalculates preGain value.According to calculating
Obtained basic volume inquires mapping table again, to obtain corresponding IEQ gain, and sends configuration-direct to configuration unit, uses
In the IEQ gain of configuration target equalizer.
Here, the executing subject of step 201 to step 206 can be the processor of electronic equipment.Electronic equipment can be
Has the electronic equipment of audio output function, for example, mobile phone, tablet computer, laptop, desktop computer, intelligent sound box etc..
It by adopting the above technical scheme, is the different adjustable gain range of equalizer setting according to different level of sound volume, especially
It is in high volume levels for the lesser adjustable gain range of equalizer setting, is that equalizer setting is larger in amount of bass grade
Adjustable gain range, in this way, the level of sound volume of electronic equipment gone when being in higher level adjustment balanced device gain, can keep away
Exempt to be arranged due to equalizer gain excessive, upper limit value of the system sound volume for causing electronic equipment to export more than security regulations.
