Ear line information, and according to the acoustic feature model of the ear line information architecture user；Audio status is played when the earphone is in
When, obtain the leakage rate of sound；And the output volume of earphone described in the big minor adjustment according to the leakage rate.Pass through above-mentioned side
Method can realize the automatic adjustment of earpiece volume according to the size of the sound leakage rate of earphone, make user in the mistake for wearing earphone
Volume need not be adjusted in journey manually and can be obtained suitable volume, promotes the audio experience of user.
In one embodiment, as shown in figure 4, it is described when detecting that earphone is inserted into user's ear, according to currently playing
Audio signal obtain associated with the ear internal structure of active user acoustic feature model, specifically include following steps
402~step 406：
Step 402：Obtain the currently playing audio signal of the earphone；
The currently playing audio signal of earphone is obtained, which can be the multimedia text that default application program plays
Part and the voice signal other than the music, voice signal or the hearing user range that send out, which can also be to pass through
The voice signal etc. of user or contact person in journey.
Step 404：Based on the electroacoustic transducer for playing the audio signal, the audio signal is acquired by inside ear
The echo signal formed after the reflection and vibration of structure；
Earphone includes electroacoustic transducer, and electroacoustic transducer can be used as loud speaker, and the corresponding electric signal of audio signal is turned
Change the acoustic signals that user can hear into.Meanwhile electroacoustic transducer is non-to the sound wave in user's ear internal structure (duct)
It is often sensitive, the vibration of diffuser can be caused, the coil being connected with cone is driven to be cut in the magnetic field of permanent magnet
The movement of the magnetic line of force, to generate the electric current changed with the variation of sound wave, (the phenomenon that generating electric current is physically being known as
Electromagnetic induction phenomenon), meanwhile, it will export the electromotive force of audio at coil both ends.Therefore, electroacoustic transducer can also acquire audio
The acoustic echo signal that signal generates after the reflection of ear internal structure and vibration.That is, electroacoustic transducer can also be made
It is used for microphone.Wherein, the principle of microphone is after the electroacoustic transducer carries out energy reverse transformation, by acoustical signal

Wherein, audio signal earphone speaker played is s (t), the acoustic echo in the collected duct of microphone
Signal is r (t), and acoustic feature model associated with the ear internal structure of active user indicates with w (t), therefore can be with
Obtain following expression：
R (t)=s (t) * w (t) (1)
In formula, w (t) is a parameter that can reflect earphone and user's ear coupling, can be used for characterizing earphone and be put
Set the acoustic feature in the space in user's ear.In formula (1), audio signal is s (t) and acoustic echo signal is that r (t) can
It is monitored and is obtained with the voicefrequency circuit by earphone or electronic equipment setting, and then the ear internal junction with active user can be obtained
The associated acoustic feature model w (t) of structure.Wherein, acoustic feature model w (t) can be understood as earphone and be currently located user's ear
The space characteristics of piece internal structure, that is, user's ear can be located to characterize earphone with different acoustic feature model w (t)
Internal different location.Correspondingly, the ear line feature of each user can also be characterized with acoustic feature model w (t).
Further, a noise factor e (t) can also be increased in above-mentioned formula (1), wherein noise factor e (t) includes

It is found that when user is kept in motion lower wearing earphone, with the increase of time t, pass through the sound for the user that earphone is got
It learns characteristic model w (t) and the trend gradually risen is presented, since acoustic feature model w (t) indicates that earphone is currently located user's ear
The space characteristics of internal structure show that the phenomenon that loosening outward occurs in the position that earphone is located inside user's ear, namely show
The amount of leakage of sound increases at this time.As the above analysis, the change curve for the user acoustic feature model w (t) that earphone obtains
The leakage variable quantity for characterizing the sound that earphone is sent out in user's ear, to the change curve of the acoustic feature model w (t) into
It can be obtained the leakage variable quantity of sound after row integral operation, function expression is represented by：
Optionally, during user wears earphone, when earphone is depressed or other external impacts, earphone is in ear
Internal position is also possible to be offset inward, that is to say the acoustic feature model w (t) of user with the increase of time t occur by
Downward trend is walked, the amount of leakage of sound can reduce at this time.Similarly, the change curve of structure acoustic feature model w (t), to this
It can be obtained the leakage variable quantity of sound of the earphone to ear internal blas when after change curve progress integral operation.
