Embodiment
To enable goal of the invention, feature, the advantage of the present invention more obvious and understandable, below in conjunction with the present invention
Accompanying drawing in embodiment, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described reality
It is only part of the embodiment of the present invention to apply example, and not all embodiments.Based on the embodiment in the present invention, people in the art
The every other embodiment that member is obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Due in the prior art, when debugging the power output of audio frequency apparatus, it is necessary to according to volume register data table
Last value, that is, corresponding volume register value when volume is 100, then down debug successively volume be 99,
98th, the volume register value corresponding to 97 ... 2,1,0, workload is big, and efficiency is low；And entered at the same time using multiple parameters
During row debugging, easily occur that a certain parameter is bigger than normal and the unusual limit, and the less situation of other parameter, it is difficult to determine specified defeated
Go out power.
In order to solve the above-mentioned technical problem, the present invention proposes a kind of adjustment method of audio frequency apparatus power output, reference picture
1, Fig. 1 for first embodiment of the invention sound intermediate frequency equipment power output adjustment method schematic flow sheet, the embodiment of the present invention
In, the above method includes：
Step 101, after debugging instruction is received, the audio is determined according to the volume controlling curve template pre-set
The volume controlling curve of equipment；
In the embodiment of the present invention, it is contemplated that the volume register data table used in debugging volume controlling curve, in difference
It can be shared in scheme, therefore, a volume controlling curve template can be pre-set, for same type of audio frequency apparatus,
The volume controlling curve template can be directly invoked in debugging, it is not necessary to debugged successively again each in volume register data table
Individual numerical value.
It is specifically, further comprising the steps of before above-mentioned steps 101：
Step A：Operated in response to configuration, according to the register value corresponding to the max volume value of the audio frequency apparatus,
It is determined that the register value corresponding to remaining each volume value；
In the embodiment of the present invention, the first register count according to corresponding to the max volume value (such as 100) of above-mentioned audio frequency apparatus
Value, it is determined that the register value corresponding to remaining each volume value, for example, it is assumed that the max volume value 100 of above-mentioned audio frequency apparatus
Corresponding register value is 200, therefore, can be with and because the register value corresponding to minimal volume value 0 is generally 0
Register value corresponding to volume value 1 is arranged to 2, the register value corresponding to volume value 2 is arranged to 4, with such
Push away, the register value corresponding to volume value 99 is arranged to 198.
Step B：According to the register value corresponding to all volume values of the audio frequency apparatus, the volume is set to control
Template curve.
In the embodiment of the present invention, it is determined that after register value corresponding to all volume values of above-mentioned audio frequency apparatus,
