Abstract

The invention discloses a process for attaching cloth to a special-shaped metal loudspeaker box. The process comprises the steps of obtaining PU cloth and a metal sheet with the size matched with that of a loudspeaker box shell through cutting, punching barbs on the metal sheet, and punching elastic pieces on the loudspeaker box shell; attaching one side face of the metal sheet to the inner side of the PU cloth, and inserting the barbs into the PU cloth; attaching a hot melt adhesive film to the other side face of the metal sheet to form semi-finished cloth, downwards pressing the loudspeaker box shell for the first time, enabling the bottom face of the loudspeaker box shell to abut against the hot melt adhesive film and attaching the hot melt adhesive film to the surface of the loudspeaker box shell, and embedding the elastic pieces at the bottom of the loudspeaker box shell into the hot melt adhesive film; downwards pressing the loudspeaker box shell for the second time, providing elastic acting force by a lower jig, and when the loudspeaker box shell moves downwards, wrapping the surface of the loudspeaker box shell with the remaining semi-finished cloth according to the shape of the loudspeaker box shell by using the lower jig. The metal sheet can provide a supporting effect for the PU cloth, the cloth can be attached according to the special-shaped structure of the loudspeaker box shell, it is guaranteed that the cloth can be completely attached to the loudspeaker box shell, and the consistency of the cloth and the loudspeaker box shell is good.

Description

technical field [0001] The invention relates to the technology in the field of sound box shell processing, in particular to a cloth attachment process for a special-shaped metal sound box shell.
