SMART SPEAKER DEVICE, AND METHOD AND SYSTEM FOR CONTROLLING SMART SPEAKER DEVICE

WIPO Patent Application WO/2021/227570

A1

Provided are a smart speaker device, and a method and system for controlling a smart speaker device. The smart speaker device comprises: a first sound detection module used to detect a first sound signal directly reaching the first sound detection module; a second sound detection module used to detect a second sound signal directly reaching the second sound detection module, wherein the first sound signal and the second sound signal are simultaneously emitted by the same sound emission apparatus; an angle determination module used to determine a time difference between a reception time of the first sound signal and a reception time of the second sound signal, wherein a relative angle between the smart speaker device and the sound emission apparatus is determined on the basis of a distance between the first sound detection module and the second sound detection module and the time difference; and a sound emission module used to directionally emit sound to the sound emission apparatus on the basis of the relative angle. The invention implements directional sound emission by calculating a relative angle.
