摘要

The loudspeaker has an assembly cone with a smaller diameter end (6) connected with a voice coil body (5) and a lower centering (7). A large diameter end (1) of the assembly cone is connected with a diaphragm (2) and upper centering (9), where the diaphragm has arbitrary shape. The assembly cone has an adhesive gap and another adhesive gap (10) for assembling the upper centering, where the assembly cone has ventilation openings. The assembly cone is riveted with the diaphragm, where the assembly cone is made of plastic by injection molding.
