Abstract: This invention provides a speaker cabinet, and the aforementioned speaker cabinet includes a containment space within; multiple reinforcing rib connectors pass through the space between the two faces on the inside of the aforementioned containment space with the largest area; when these two faces start moving towards or away from each other, the reinforcing rib connectors provide resistance in the opposite direction of the movement; the aforementioned cabinet and reinforcing rib connectors are created in one piece via extrusion blow moulding. The invention provides a speaker cabinet, where the total capacity of the cabinet can remain unchanged during use, and the cabinet is very light-weight, and the inner walls of the cavity are also very thin. Completely fulfils sound quality and portability requirements.

Abstract: This invention discloses a kind of speaker structure with a loading hole. A characteristic is that it includes an active cavity that has a cone hole and a loading hole; a loudspeaker is sealed and secured on the said cone hole; the said active cavity is connected to the outside air through the said loading hole; the cone of the said loudspeaker has one side which is connected to the free space; another characteristic of this invention is that it includes a driven cavity that is connected to the said active cavity through the said loading hole; the cross-sectional area of the said loading hole is smaller than the cross-sectional area of the air passage on its either side; further, it is not larger than ? the effective area of all the vibration units in the said active cavity; also, the volume of the said active cavity does not exceed half the total volume of the said active cavity and driven cavity. The loading hole constitutes a loading component which improves the transient response of the speaker body.
