Extrusion blow molds and manufacturing methods for certain speaker cabinets and speaker cabinets

摘要

The present invention provides a speaker cabinet. The speaker cabinet has a closed space inside, and a plurality of reinforcing rib connectors pass through the space between the two surfaces having the maximum area inside the closed space. When these two surfaces begin to move closer to or further from each other, the reinforcing rib connector provides resistance in the opposite direction of the movement. The speaker cabinet and the reinforcing rib connector are integrally manufactured by extrusion blow molding. The present invention provides a speaker cabinet in which the total capacity of the speaker cabinet can not be changed during use, the cabinet is very lightweight, and the inner wall of the cavity is also very thin. Sufficiently meet the requirements for sound quality and portability. [Selection diagram] Fig. 1
