In practical application, the calibration parameters can perform corresponding phase compensation and gain setting on the first parameters, so that more accurate initial parameters can be obtained, and the noise reduction effect on the voice signals is improved. In practical applications, when the folding angle changes, the distance parameter and the phase parameter in the first parameter also change, so that the required calibration coefficients also differ. In practical applications, due to the limitation of robustness of the algorithm, when the distance between the two microphones gradually approaches, the noise reduction effect will be deteriorated, and therefore, different calibration coefficients need to be called to ensure the noise reduction effect of the voice signal.
In an embodiment, as shown in fig. 5, the invoking a calibration coefficient corresponding to a folding angle of the folding screen to calibrate the first parameter and generate a second parameter includes:
s501: and determining a first angle range in which the folding angle of the folding screen is located.

After the foldable angle of the foldable screen is divided into different ranges, a first angle range is determined according to the foldable angle of the foldable screen, for example, when the foldable angle of the foldable screen is 30 °, the first angle range in which the foldable angle of the foldable screen falls is 0 ° to 45 °.

In practical application, the more the value ranges divided by the foldable angles are, the calibration coefficients corresponding to different angles can be accurately obtained, and the noise reduction effect of the voice signal can be improved.
