摘要： 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.

摘要： The invention provides a speaker module for a mobile terminal with a sound output port. The speaker module includes a speaker box. The speaker box includes a sound output opening for side surface sound. The speaker module also includes a horn barre. The horn barrel has openings arranged at both ends. A sectional area along the sound output direction of the horn barrel changes gradually. By designing a variable sectional surface with different areas or lengths and widths on the horn barrel for stakeout, the size of the variable sectional surface is directly related to the sound quality of each part of the horn barrel. The horn barrel widens the frequency band range. Compared with the related art, the present invention can realize multi-level resonance, has a small volume, is convenient to widen the frequency band range and has flexible avoidance space.

摘要： A flat panel loudspeaker configured for mounting in an opening in a mounting surface includes a planar resonant panel configured to be inserted into an opening in the mounting surface and having a front surface and a rear surface. The flat panel loudspeaker also includes an exciter coupled to the rear surface and configured to cause an active portion of the planar resonant panel to vibrate and generate sound. An outer boundary of the active portion of the planar resonant panel is fixed relative to the mounting surface, the outer boundary defining the active portion as an area of the planar resonant panel. The planar resonant panel comprises an edge portion extending beyond the outer boundary of the active portion in at least one direction. The edge portion is configured to overlap the mounting surface.
