Loudspeaker dustproof net preparation method, loudspeaker dustproof net and sound box

The invention relates to a loudspeaker dustproof net preparation method, a loudspeaker dustproof net and a loudspeaker box, the loudspeaker dustproof net preparation method comprises the following steps: providing VHB adhesive tape feeding, the feeding direction of the VHB adhesive tape being a first direction; feeding of a gauze tape is provided, the gauze tape is subjected to die cutting to form gauze, the gauze is attached to the VHB adhesive tape, the feeding direction of the gauze tape is a second direction, and the second direction and the first direction are inclined to form a preset angle; and the PSA pressure-sensitive adhesive is attached to the gauze to form the horn dust screen. Compared with a traditional mode that the first direction and the second direction are directly overlapped, the horn dustproof net manufacturing method has the advantages that the first direction of VHB adhesive tape feeding and the second direction of the gauze tape feeding are adjusted to form the preset angle, so that w
