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 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.

Abstract: Provided in the present application are an acoustic reinforcing material block and an application thereof, a micro loudspeaker and an electronic device. The raw materials of the acoustic reinforcing material block include a porous material, an adhesive, and an adjuvant loaded in a structural framework. The micro loudspeaker comprises an upper housing and a lower housing which form an inner cavity, and a loudspeaker unit located in the inner cavity, wherein the inner cavity is divided into a front cavity and a rear cavity, and the front cavity is in communication with a sound outlet hole; and a front cavity resonant cavity which is in communication with the front cavity and filled with an acoustic enhancing material is provided in the upper housing.

Abstract: The present disclosure provides a porous bulk material and an electronic apparatus thereof, and an apparatus capable of reducing wind noise and an application thereof. The apparatus comprises an external sound channel, a zeolite material, and a sound pickup hole, wherein the zeolite material is disposed between the external sound channel and the sound pickup hole. The present disclosure further provides an application of the apparatus in an electronic device provided with a microphone. According to the apparatus, the wind noise can be effectively reduced, and the call quality of a communication device is obviously improved.
