Abstract

The invention relates to an acoustic generator vibrating membrane back adhesive patch production method. According to the method, an adhesive layer of a main material is attached onto a first membrane, a shape needed by back adhesive is formed through stamping, a first transparent adhesive tape is torn, first membranes and release membranes thrust at a first positioning hole, a back adhesive shapeforming hole and a second positioning hole are taken away by the first transparent adhesive tape, the release membranes are attached and torn by a second transparent adhesive tape, part of adhesive except for the back adhesive shape forming hole is taken away by the release membranes, and a needed back adhesive shape is formed by discharging waste twice. The acoustic generator vibrating membraneback adhesive patch production method can produce acoustic generator vibrating membrane back adhesive patches in bulk, production efficiency is high, and automation is easily achieved.

Description

technical field [0001] The application belongs to the technical field of adhesive production methods, and in particular relates to a production method for a vibrating film adhesive patch of a sounder. Background technique [0002] The headphone speaker usually includes a central ring recess in the bottom shell. Magnets, front pole pieces, voice coils, diaphragms and covers are placed in the central ring recess in sequence from bottom to top. The bottom shell is combined with a terminal on the bottom side of the edge wall. The plate is used for the lead wire of the voice coil to pass through and is lapped and welded on the terminal plate. The diaphragm is combined with a metal ring on the periphery of the diameter, and a back adhesive layer is coated on the ring-shaped area on one side of the diaphragm. At present, there is no good production process for ring adhesive, and the degree of automation is not high. Contents of the invention [0003] The technical problem to be ...
