Midpoint between sensor 2053 and falling tone sensor 2054, and third loudness and the 4th loudness have differences
When, then it can be taken between third acoustic sensor 2053 and falling tone sensor 2054 according to third loudness and the 4th loudness
Ratio cut-point as site 2056 in second.
Step 4015 determines Sounnd source direction according to site in site in first and second.
Determining in first in site 2055 and second after site 2056, can according to site 2055 in first and
Site 2056 determines Sounnd source direction in second, wherein Sounnd source direction is that site 2055 in first is directed toward in site 2056 in second
Direction vector, i.e. Sounnd source direction are directed toward sound source 400.
Step 402, the gyration vector that vehicle-mounted bracket is determined according to Sounnd source direction.
Specifically, can be the angle according to Sounnd source direction and the current direction of vehicle-mounted bracket after determining Sounnd source direction
Deviation, also, determine according to angular deviation the gyration vector of vehicle-mounted bracket, gyration vector includes: rotation direction and angle of rotation
Degree.So that setting motor is rotated according to rotation direction and rotational angle, so that vehicle-mounted bracket direction after rotation
Sound source 400.
In the present embodiment, by according to each acoustics sensor being arranged in the acoustic sensor array on vehicle-mounted bracket
The property difference of voice signal accessed by device determines Sounnd source direction, then determines turning for vehicle-mounted bracket further according to Sounnd source direction
Dynamic vector, so that vehicle-mounted bracket is towards Sounnd source direction.So that vehicle-mounted bracket can be according to the Sounnd source direction in vehicle environment
Automatic direction adjusting is carried out, strength youngster improves the usage experience for the terminal device being arranged on vehicle-mounted bracket.
