Title:
SOUND-PRODUCING MODULE, SOUND ELIMINATION METHOD FOR SOUND-PRODUCING MODULE, AND SMART GLASSES
Document Type and Number:
WIPO Patent Application WO/2023/000597
Kind Code:
A1
Abstract:
The present application discloses a sound-producing module, a sound elimination method for the sound-producing module, and smart glasses. The sound-producing module comprises a housing and a sound-producing unit, wherein the housing comprises a moving plate and a housing body which has an accommodating cavity; the housing body is provided with a sound hole, and the moving plate is provided with a sound-releasing hole; the sound-producing unit is located in the accommodating cavity and divides the accommodating cavity into a front cavity which communicates with the sound hole and a rear cavity which communicates with the sound-releasing hole; the moving plate can move relative to the housing body so as to change the position of the sound-releasing hole relative to the sound hole. Since the moving plate can move relative to the housing body, the relative position of the sound-releasing hole and the sound hole can be changed. According to wave interference principles, it is known that the sound elimination directivity of the sound-producing module can be changed. By means of using a moving sound-releasing hole, the sound elimination directivity can be adaptively adjusted once the relative position of a crowd is determined, thereby ensuring consumer privacy to the greatest extent.
