Title:
SOUND PRODUCTION DEVICE AND CONTROL METHOD THEREFOR, AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/050971
Kind Code:
A1
Abstract:
Disclosed in the present invention are a sound production device and a control method therefor, and a control device. Two sound production units are controlled to work according to relevant parameters related to environmental noise, such that phases of sound outlet holes of the two sound production units are the same or opposite; when the environmental noise is relatively large, the two sound production units are controlled to work, such that the phases of the sound outlet holes of the two sound production units are the same to enable the sound produced by the two sound production units to have a mutual enhancement effect; and when the environmental noise is low, the two sound production units are controlled to work, such that the phases of the sound outlet holes of the two sound production units are opposite to enable the sound produced by the two sound production units to be mutually counteracted, thereby reducing the effect on an environment. Therefore, the sound production device provided by the present invention can be used in different noise environments.
