Title:
EXPANDABLE ACOUSTIC REINFORCEMENT MEMBER AND MANUFACTURING METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/020311
Kind Code:
A1
Abstract:
An expandable acoustic reinforcement member and a manufacturing method therefor and the use thereof. When one or more expansion trigger conditions are applied, an apparent volume of the expandable acoustic reinforcement member is increased, and an internal pore volume is increased. The expandable acoustic reinforcement member is applied to a loudspeaker, and an expansion trigger treatment is performed on the expandable acoustic reinforcement member, so that the apparent volume of the expandable acoustic reinforcement member is increased, and the internal pore volume is increased, such that the acoustic performance of the loudspeaker assembled with the expandable acoustic reinforcement member is improved; meanwhile, pressing is performed between the expandable acoustic reinforcement members, and between the expandable acoustic reinforcement member and a cavity wall of a specific space of the loudspeaker, so that the expandable acoustic reinforcement member is fixed, thereby achieving the effects of eliminating noise in the use process of the loudspeaker and preventing collisions and crushing of the acoustic reinforcement member to generate falling powder, and prolonging the service life of the acoustic reinforcement member.
