Description
Technical field
The application relates to electroacoustic conversion art, particularly relates to a kind of motor for acoustic apparatus, receptor and audio frequency and sets
Standby.
Background technology
Various types of mikes and receptor (transducer) have been applied to many fields of people's daily life, for people
Life bring many facilities.In these devices, different electrical components is installed together on housing or assembly
In.Such as, receptor typically can include coil, magnetic support parts, armature and magnet, and these elements are mounted
In receiver shell.Other type of acoustic apparatus can include other type of parts.
Transducer can be used in the multiple application of such as sonifer etc.Also can be at such as personal computer or honeycomb electricity
Other application of words etc uses these devices.
As it has been described above, receptor includes magnetic support parts.As the important electrical components of receptor, magnetic support portion
Part may be used for supporting or protection magnet, can be by using radium-shine welding by magnetic support parts and receiver shell phase
Fixing.
Typically can use to extrude or stack technique and prepare magnetic support parts.Stack technique with employing and prepare magnetic support
As a example by parts, it can be had certain thickness lamination and stacked by multiple and make, and generally, lamination can use stamping-out work
Skill prepares.For ensureing that receptor has preferably performance, typically require the concordance of the inner space of magnetic support parts
Preferably, described concordance may refer to the inner space of magnetic support parts for supporting the flatness of the inwall of magnet.
Therefore, this is to using punching process to propose higher requirement with prepared lamination；And stamping-out can produce blanking accordingly,
Thus causing the waste of raw material, cost increases.Extrusion process is used to prepare magnetic support parts then mould used to extruding
The bearing capacity of tool and the raw-material plastic fluidity of preparation magnetic support parts have higher requirement.Concrete,
The raw material of preparation magnetic support parts is squeezed the effect of power in extrusion die cavity, produces plasticity through mould outlet and becomes
Shape also ultimately forms magnetic support parts.In the process, raw material applies bigger action of compressive stress to extrusion die；
And on the other hand, raw material should have preferably plastic fluidity.So so that use the mode of extruding to prepare magnetic
There is the problem that processing technique is more complicated in support member.
And solve to extrude or stack technique and prepare the problems referred to above that magnetic support parts exist, generally can use sheet metal worker
Skill prepares magnetic support parts.Concrete, substantially square plate can be bent to form described magnetic part.
Utilize sheet metal process that the manufacturing process of magnetic support parts and flow process can be made to be greatly simplified, thus improve manufacture efficiency fall
Low production cost.And owing to the surface of the original plate for manufacturing magnetic support parts can be more smooth, therefore can make
The concordance of the inner space obtaining the magnetic support parts that sheet metal obtains is preferable.
Generally, would generally there is fillet at bending part in the magnetic support parts utilizing sheet metal process to prepare, the product of fillet
Life can cause existing between magnetic support parts and receiver shell bigger gap.Now it is intended to utilize radium-shine welding to two
When person is fixed, the melted material of generation is difficult to this bigger gap filling full, so causes radium-shine failure welding
(laser rejections), causes easily loosening between magnetic support parts and housing.Time serious, melted material will along this relatively
Big gap falls in housing, so will be unable to the gap filled between the two, thus cause magnetic support parts without
Method is fixed with housing.
