Tool and process for producing diaphragm of loudspeaker

Abstract

The invention relates to a tool for producing a diaphragm of a loudspeaker. The tool comprises a substrate and a seat cover, wherein a plurality of round locating slots are formed in the surface of the substrate, a first ring groove and a second ring groove are formed in each locating slot, each first ring groove and the corresponding second ring groove are concentric, each second ring groove is arranged at the outer side of the corresponding first ring groove, a central hole is arranged in each first ring groove, line pressing grooves and lead grooves communicated with the locating slots and the line pressing grooves are arranged in positions, which are arranged at two sides of the locating slots, on the substrate, each lead groove is arranged on the central line of the corresponding locating slot and is vertical to the corresponding line pressing groove, and the substrate is further provided with limited posts; compressing grooves matched with the locating slots are arranged in the substrate, a round locating column and an arc-shaped hole concentric to the locating column are arranged at the center of each compressing groove, line clip grooves corresponding to the lead grooves are arranged in the seat cover, and a line clip structure is formed by each lead groove and the corresponding line clip groove. The tool has the characteristics of automatic operation and capabilities of avoiding inconsistent line stack effect of a voice coil, which is caused by manual operation, and effectively controlling line stack force of a lead and the like.

Description

technical field [0001] The invention relates to the technical field of loudspeaker voice coil sound film gluing, in particular to manufacturing tooling and technology of the loudspeaker diaphragm. Background technique [0002] The diaphragm is composed of a sound film and a voice coil. At present, the pointing method of the sound film is to lead the two leads of the voice coil from the same point, and fix the two leads on the sound film with glue, and then use glue to point the lead wires of the voice coil on the sound film. On the membrane, the lead wires and dotted lines are generally completed by manual cooperation, and the shape and glue volume of the dotted lines are completely controlled manually, but the voice coil and the sound membrane are comparative devices, requiring high precision and quality. Manual cooperation cannot meet the specified requirements, which will result in low gluing efficiency, low output, inconsistent wire loosening effect, and inconsistent con...
