EXPANDABLE ACOUSTIC REINFORCEMENT MEMBER AND MANUFACTURING METHOD THEREFOR AND USE THEREOF
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 member is increased, and an internal pore volume is increased. The member is applied to a loudspeaker, and an expansion trigger treatment is performed on the member, so that the apparent volume of the member is increased, and the internal pore volume is increased, such that the acoustic performance of the loudspeaker assembled with the member is improved; meanwhile, pressing is performed between the members, and between the member and a cavity wall of a specific space of the loudspeaker, so that the member is fixed, thereby achieving the effects of eliminating noise in the use process of the loudspeaker and preventing collisions and crushing of the member to generate falling powder, and prolonging the service life of the member.
