Description
Technical field
The invention belongs to earphone noise reduction technology field more particularly to a kind of control earphone noise-reduction methods and device.
Background technology
Noise pollution is as one of internationally recognized four big pollutions, with the development of urbanization and the progress of technology, noise
Pollution also becomes more serious.It, can be by controlling earphone noise-reduction method, drop when user plays audio by terminal peripheral earphone
Low environment noise protects the hearing of user.
Earphone noise-reduction method used at present, there are two types of realization method, first way be by earphone physically every
Disconnected noise, makes it cannot be introduced into human ear；The second way is that earphone collects noise, inside earphone into the reverse phase of Row noise with
Superposition offsets the noise into earphone, makes human ear that can not perceive.
However, existing earphone noise-reduction method, needs the hardware switch of the setting adjusting noise reduction on earphone, is unfavorable for earphone
It is highly integrated, and can not achieve automatic noise reduction.The reason is that existing earphone noise-reduction method, is all directly to be carried out using earphone
Adjust noise reduction.Using first way, user can adjust partition journey of the earphone to noise by adjusting the elastic of head wire
Degree and the comfort level worn, using the second way, user can open or close ear by switch on earphone or button
The decrease of noise functions of machine.Therefore, both modes are needed for by the hardware switch on earphone, opening or closing manually
The decrease of noise functions of earphone, it is cumbersome, noise reduction efficacy is reduced, automatic noise reduction is can not achieve.Meanwhile both modes, it needs

Wherein, using terminal microphone, the noise signal of local environment is acquired, there are three types of embodiments, and details are as follows：
The first embodiment：
Every preset assay intervals the noise signal of local environment is acquired using terminal microphone.
It should be noted that too big variation can't usually occur whithin a period of time for the noise signal due to environment, because
This, carries out one-time detection to the noise signal of environment every preset assay intervals, can further save the electricity of terminal
Consumption.
Second of embodiment：
When the distance for leaving the geographical location of noise signal of last acquisition local environment is not less than pre-determined distance, profit
With terminal microphone, the noise signal of local environment is acquired.
It should be noted that since the distance that terminal leaves the geographical location of the noise signal detection of last local environment is super
After crossing pre-determined distance, it is possible to which, because of the distance on geographical location, local environment is also changed, at this time again to local environment
Noise signal carry out one-time detection, can inform the situation of change of the noise signal intensity of user's local environment in time.
It should be noted that it is less than pre-determined distance, but the longer situation of traveling time due to being possible to occur terminal movement,
It, but can not be real-time in order to avoid the noise signal intensity of the local environment in this longer traveling time has changed a lot
Acquisition, at this point, further, step S101 is specially：
When the distance that terminal leaves the geographical location of the noise signal detection of last local environment is less than pre-determined distance
When, if the time of the noise signal detection at this time apart from terminal last time local environment has been more than preset assay intervals, eventually
End also obtains the noise signal detection for carrying out local environment,
Thus the accuracy and real-time of the noise signal detection of local environment are further improved.
Similarly, it should be noted that, the GPS functions that can be carried by terminal obtain the progress of terminal current distance last time
The distance in the geographical location of the noise signal detection of local environment, to judge whether the terminal leaves ring residing for last carry out
The distance in the geographical location of the noise signal detection in border is less than pre-determined distance.
The third embodiment：
When terminal is located at preset location, using terminal microphone, the noise signal of local environment is acquired.
Wherein, preset location can be one or be multiple simultaneously, if preset location is multiple, when described mobile whole
