Abstract
The invention relates to an assembly process for a post-installation magnetic circuit of a loudspeaker. A voice coil positioning gauge jig is used in the assembly process. The assembly process includes the first step that a magnet and a spring washer are placed into a permeability bowl in sequence, and the magnet and the spring washer are bonded through glue to form the magnetic circuit; the second step that the voice coil positioning gauge is installed into a permeability bowl hole of a basin rack from the lower surface of the basin rack, a voice coil is fixed on the voice coil positioning gauge in a plugged connection fit mode, and the voice coil and a soldering lug are soldered together through a built-in guide wire of the voice coil to be combined into an assembly intermediate body; the third step that a vibrating diaphragm is in center alignment with the voice coil, the vibrating diaphragm and the voice coil are bonded together through the glue, and the edge of the vibrating diaphragm and the basin rack are bonded together through the glue; the fourth step that the voice coil positioning gauge is taken out from the permeability bowl hole of the basin rack, the magnetic coil is placed into the permeability bowl hole of the basin rack in a plugged connection fit mode, and the magnetic circuit and the permeability bowl are bonded into a whole through the glue. The assembly process has the advantages of reducing the positioning process when the voice coil is assembled at a time, greatly reducing the probability of voice coil deviation and improving yield of products.
Description
Technical field
The present invention relates to a kind of loud speaker assembly technology, particularly after a kind of loud speaker, magnetic circuit assembly technology is installed.
Background technology
At present, the diaphragm of loudspeaker and voice coil loudspeaker voice coil are combined into the manufacturing process of sound film group, mainly by tool fixture, undertaken, dimensional fits by basin frame group and sound film group is realized location, because material itself and tool fixture exist tolerance and assembling process to have the factors such as accumulated tolerance, make to have the voice coil loudspeaker voice coil hidden danger of circle partially in final loudspeaker unit, cause final decrease in yield.
Summary of the invention
Problems and shortcomings in view of above existence, after the invention provides a kind of loud speaker, magnetic circuit assembling new technology is installed, concrete technical scheme is, magnetic circuit assembly technology is installed after a kind of loud speaker, Assembly part comprises washer, magnet, magnetic conductor bowl, basin frame, voice coil loudspeaker voice coil, vibrating diaphragm, weld tabs, it is characterized in that: in assembling, use voice coil positioning gage tool, assembly technology flow process comprises the following steps
1., magnet, washer are put into successively to magnetic conductor bowl and by the bonding magnetic circuit that is combined into of glue;
2., voice coil positioning gage is packed into below basin frame in the magnetic conductor bowl hole of basin frame, voice coil loudspeaker voice coil plug connects and is fixed on voice coil positioning gage, wire and weld tabs that voice coil loudspeaker voice coil carries with it weld together, and are combined into assembling intermediate;
3., by vibrating diaphragm and voice coil loudspeaker voice coil center-aligned and bond together with glue, vibrating diaphragm edge and basin frame glue bond together;
4., voice coil positioning gage is taken out in the magnetic conductor bowl hole of basin frame, magnetic circuit plug is connect in the magnetic conductor bowl hole of Combined with Radiotherapy engagement frame, and be integral with glue is bonding.
Described voice coil positioning gage tool is a ladder important actor being comprised of four cylinders that diameter does not wait from small to large, wherein go up most ground floor cylinder diameter Cheng Sai identical with voice coil loudspeaker voice coil internal diameter and connect cooperation, height is identical with voice coil loudspeaker voice coil height 1/2, and second layer cylinder diameter is identical with magnetic circuit external diameter.
The invention has the beneficial effects as follows the position fixing process while having reduced by a voice coil loudspeaker voice coil assembling, greatly reduce the voice coil loudspeaker voice coil probability of circle partially, improved the rate of finished products of product.
