Abstract
A method, applied to a mobile terminal having at least two loudspeakers, includes: setting direction information of a target sound field; and determining filtering parameters of at least two filters according to the direction information. The filters have a one-to-one correspondence with the loudspeakers, and are configured to filter audio signals to be output. The audio signals are filtered using the filtering parameters, to at least adjust phases of the audio signals. The adjusted audio signals are output by the loudspeakers. After the audio signals output by the different loudspeakers are superimposed, the superimposed signal is consistent with a direction indicated by the direction information.
