Abstract

The invention discloses a sound field expansion method, device and system of a sound box and a computer readable storage medium, is applied to the technical field of audio equipment, and aims to solve the problem that the sound field is small due to the fact that the size of an existing dual-track small intelligent sound box is small and the installation space of a loudspeaker is limited. Obtaining an original left channel audio signal and an original right channel audio signal of an audio signal to be played; respectively carrying out difference expansion processing on the original left channel audio signal and the original right channel audio signal to obtain a final left channel audio signal and a final right channel audio signal; according to the invention, the sound field of the sound played by the left and right loudspeakers in the subjective hearing of the user is wider in the use process, and the sound effect and the user experience can be improved.

Description

technical field [0001] The present invention relates to the technical field of audio equipment, and in particular, to a sound field expansion method, device, system and computer-readable storage medium of a speaker. Background technique [0002] In recent years, smart speakers have become more and more widely used in the home, especially the small two-channel smart speakers are more and more popular. However, due to the small size of the two-channel small smart speakers, the installation space of the speakers is limited, so Restricted by the position of the left and right two-channel speakers, when the two-channel small smart speaker plays music, the user cannot achieve an open sound field in terms of subjective hearing, which affects the user experience. [0003] In view of this, how to expand the sound field of the speaker and improve the sound effect and user experience of the speaker has become a problem to be solved by those skilled in the art.
