It is sent to noise reducing apparatus via short range communication module, as long as mobile terminal and noise reducing apparatus establish junction service annexation,
Enter noise reduction mode of operation.
Generally, in car as a example by active noise reduction, noise reducing apparatus can store the inner space configuration information of relevant vehicle, and
Need in car by mobile terminal strengthen noise reduction region can enumerate, such as, at center armrest, main driving position storage
In thing case, co-driver, co-driver storage tank, player No.5, heel row, the information such as back right, these regions can be as movement
Terminal reference position information in car, is sent to noise reducing apparatus (such as, ANC system side apparatus), by noise reducing apparatus according to phase
Close the inner space configuration information of vehicle, determine mobile terminal positional information in car, and the mobile terminal of respective model
The position of mike, determine the mike of the mobile terminal reference coordinate information in car, so can save sound localization
Module.
Alternatively,
Described information sending module 14, is additionally operable to the mutual alignment information of the speaker by described mobile terminal and mike
Issue described noise reducing apparatus.
Mobile terminal can also by the locally downloading storage of mutual alignment relation information of the mike of self and speaker,
And when connecting with noise reducing apparatus (such as, ANC system side apparatus), it is sent to noise reducing apparatus, so long-range without noise reducing apparatus
Retrieval and download relevant information, or when the relational structural information of noise reducing apparatus inconvenience remote download mobile terminal, it is also possible to
Determine the mike of the mobile terminal positional information in car.
The active noise reducing device that the application provides, mobile terminal, can be according to client as the expansion equipment of noise reduction system
Need, neatly mobile terminal is placed on the position, relevant range needing to strengthen noise reduction, noise measuring can be improved
Degree of accuracy, in order to the built-in process chip of noise reducing apparatus can be according to the noise signal and original solid of mobile terminal mike detection
Determine the noise signal of mike detection, generate the de-noising signal with correlated noise signal opposite in phase, raising by noise reducing apparatus
This de-noising signal play by sound device, strengthens noise reduction；When the speaker of mobile terminal is suitable for playing de-noising signal, by movement
The speaker of terminal plays de-noising signal, can further enhance noise reduction.
