Acoustic response characteristic different everywhere on the screen or shell of electronic equipment and distribute different acoustics signal processing configurations, make electricity
Identical/similar acoustics effect can be generated by being respectively under corresponding acoustics signal processing configuration on the screen or shell of sub- equipment
Fruit.It should be noted that the equal flexibly configurable of shape, size and quantity that the screen of electronic equipment divides, specific to divide
Mode is as shown in Figure 4.
About the step S21, it specifically can refer to following steps progress: being distributed as according to the acoustic response the multiple
Acoustics signal processing configuration is formulated in different sound-emanating areas respectively, so that the acquisition of the plurality of different sound-emanating areas is consistent
Audio frequency effect.
About the step S11, can by the sensor (for example, ultrasonic sensor) that is arranged on electronic equipment come
The screen of user's ear and electronic equipment or the relative position of shell are monitored, so that it is determined that LisPos are on the electronic equipment
Locating sound-emanating areas can not also additionally increase sensor, and pass through the capacitance touching control screen sensing electronic equipment of electronic equipment
The ear of user sound-emanating areas locating on the electronic equipment.
It preferably, can also include detecting whether the electronic equipment is in earpiece operating mode before step S11
Step, as shown in Figure 5.It executes and then carries out " step S31: detecting that the electronic equipment is in earpiece operating mode "
The LisPos of step S11 detect, so that the detection of LisPos is only executed when electronic equipment enables handset mode, and at it
When his mode (such as earphone exports audio mode), because not utilizing screen or shell sounding, without being adjusted according to LisPos
The configuration of the acoustics signal processing of screen or shell.
About the step S12, behind the sound-emanating areas locating for abovementioned steps S11 setting LisPos, can utilize should
Then sound-emanating areas corresponding acoustics signal processing configuration utilizes treated the audio-signal-driven hair to handle audio signal
Sound area domain exports acoustic vibration and sounding, to export the audio output effect for being able to use family and obtaining consistent audio experience；
Specifically, the step 12, which further includes steps of, searches the configuration form to obtain LisPos institute
Locate the corresponding acoustics signal processing configuration in sound-emanating areas；Audio is believed using the acoustics signal processing configuration found
Number handle and according to sound-emanating areas output acoustic vibration and sounding locating for treated audio-signal-driven LisPos.
It should be noted that above various methods the step of divide, be intended merely to describe clear, when realization can be merged into
One step splits certain steps, is decomposed into multiple steps, as long as comprising identical logical relation, it is all special at this
In the protection scope of benefit；To added in algorithm or in process it is inessential modification or introduce inessential design, but
The core design of its algorithm and process is not changed all in the protection scope of the patent.
