Abstract
The present invention relates to field of acoustics, disclose the dynamic ferrum loudspeaker of a kind of corrosion protection voice coil loudspeaker voice coil, including a upper shell, a lower house, in upper shell and lower house, be provided with motor sub-assembly, be additionally provided with LP blades layer in dynamic ferrum loudspeaker, LP blades layer be arranged on upper shell and or lower house inner surface on.In terms of existing technologies, the present invention by loudspeaker upper shell and or lower house inner surface on LP blades layer oxygen in consuming loudspeaker is set, instead of over weld Copper Foil.Thus solve the problem that in prior art, extra soldered Copper Foil has the risk that comes off when in use.
Description
Technical field
The present invention relates to field of acoustics, be specifically related to the dynamic ferrum loudspeaker of a kind of corrosion protection voice coil loudspeaker voice coil.
Background technology
In order to reduce cost, dynamic ferrum loudspeaker more and more use Self-binding cord to process voice coil loudspeaker voice coil, compare enamel-covered wire and add epoxy
The method for winding of resin glue, the protection of voice coil loudspeaker voice coil reduces much, is effectively protected voice coil loudspeaker voice coil (mainly preventing the corrosion of enamel-covered wire)
It it is unusual key.A kind of method is the enclosure interior a piece of Copper Foil of welding at dynamic ferrum loudspeaker, consumes relative closure shell with it
The oxygen in internal portion, to delay the erosion to voice coil loudspeaker voice coil.This method is since it is desired that the making of extra soldered, and cost advantage is little, and
And have the potential risk come off.For avoiding the problem that extra soldered Copper Foil has the risk that comes off when in use.Therefore, need to be to existing
Technology is had to be improved.
Summary of the invention
The invention provides the dynamic ferrum loudspeaker of a kind of corrosion protection voice coil loudspeaker voice coil, the most extra in order to solve in prior art
The problem that welding Copper Foil has the risk that comes off.
For achieving the above object, the technical solution used in the present invention is:
Described dynamic ferrum loudspeaker are provided with groups of motors in including a upper shell, a lower house, described upper shell and described lower house
Part, is additionally provided with LP blades layer in described dynamic ferrum loudspeaker, described LP blades layer be arranged on described upper shell and or described lower house in
On surface.
In terms of existing technologies, by the upper shell of loudspeaker and or lower house inner surface on arrange LP blades layer use
Oxygen in consuming loudspeaker, the Copper Foil of the welding of instead of over.Thus solve in prior art the most extra
The problem that welding Copper Foil has the risk that comes off.
Further, described motor sub-assembly includes armature, iron core and voice coil loudspeaker voice coil.
Further, described voice coil loudspeaker voice coil is Self-binding cord voice coil loudspeaker voice coil.
Further, described LP blades layer thickness is less than one millimeter.
Further, described LP blades layer thickness is 3-5 micron.
Further, described LP blades layer is arranged on described upper shell and or described lower house inner surface in the way of plating
On.
Further, described LP blades layer is arranged on described upper shell and or described lower house inner surface in the way of hot pressing
On.
Further, described LP blades layer is copper LP blades layer.
Further, described copper LP blades layer is provided with silver or other high potential metals.
Due to the fact that the above technical scheme of use so that it is have the beneficial effect that
The present invention by loudspeaker upper shell and or lower house inner surface on LP blades layer is set in consuming loudspeaker
Oxygen, instead of over welding Copper Foil.Thus solve in prior art extra soldered Copper Foil when in use and have de-
The problem of the risk that falls.The Copper Foil of LP blades layer is made firmly to be attached to by improving modes such as using plating, hot pressing further
On housing and lower house inner surface.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of the dynamic ferrum loudspeaker of a kind of corrosion protection voice coil loudspeaker voice coil of first embodiment of the invention；
Reference in corresponding Figure of description is with reference to as follows:
Lower house 1, motor sub-assembly 2, LP blades layer 3, voice coil loudspeaker voice coil 4.
Detailed description of the invention
For the technological means making invention realize, create feature, reach purpose and effect is easy to understand, below in conjunction with
Accompanying drawing, is expanded on further the present invention.
First embodiment of the present invention provides the dynamic ferrum loudspeaker of a kind of corrosion protection voice coil loudspeaker voice coil, as it is shown in figure 1,
Dynamic ferrum loudspeaker include a upper shell, a lower house 1, are provided with motor sub-assembly 2 in upper shell and lower house 1, dynamic ferrum loudspeaker
Being additionally provided with LP blades layer 3 in, LP blades layer 3 is arranged on upper shell and lower house 1 inner surface in the way of plating.LP blades
Layer 3 thickness are less than one millimeter, and LP blades layer 3 preferably thickness is 3-5 micron.LP blades layer 3 is copper LP blades layer.
Motor sub-assembly 2 includes armature, iron core and voice coil loudspeaker voice coil 4.The voice coil loudspeaker voice coil that voice coil loudspeaker voice coil 4 turns to for Self-binding cord, it is also possible to be enamel-cover
The voice coil loudspeaker voice coil of line coiling.
When assembling when, upper shell and lower house 1 fasten, and are sealed in by motor sub-assembly 2 in upper shell and lower house 1.
Now, the oxygen sealed in space is consumed by crossing the copper LP blades layer at upper shell and lower house 1 inner surface, it is to avoid
The oxygen erosion to voice coil loudspeaker voice coil 4, is effectively protected life-span and the acoustics of loudspeaker.Copper oxide structure after aoxidizing due to copper causes
Close difficult drop-off, the significantly more efficient effect that loudspeaker are played protection.
Second embodiment of the present invention provides the dynamic ferrum loudspeaker of another kind of corrosion protection voice coil loudspeaker voice coil, itself and the first embodiment
Technical characteristic is similar, differs primarily in that: LP blades layer 3 is arranged on upper shell and lower house 1 inner surface in the way of hot pressing.
Third embodiment of the present invention provides the dynamic ferrum loudspeaker of another kind of corrosion protection voice coil loudspeaker voice coil, itself and the first embodiment
Technical characteristic is similar, differs primarily in that: copper LP blades layer is provided with silver or other high potential metal, now high potential metal
Effectively accelerate the Oxidation of copper, accelerate the effect consuming the oxygen sealed in space.Certainly, when upper shell and lower casing
Before body 1 not combination, silver or other high potential metals be covered, it is to avoid in advance copper LP blades layer is consumed.
In terms of existing technologies, the present invention by the upper shell of loudspeaker and or lower house inner surface on anti-invading is set
Erosion layer is used for consuming the oxygen in loudspeaker, the Copper Foil of the welding of instead of over.Thus solve in prior art use time
Wait the problem that extra soldered Copper Foil has the risk that comes off.LP blades layer is made by improving modes such as using plating, hot pressing further
Copper Foil is firmly attached on upper shell and lower house inner surface.
Above the specific embodiment of invention is described.It is to be appreciated that invention is not limited to above-mentioned specific
Embodiment, the equipment and the structure that do not describe in detail the most to the greatest extent are construed as being practiced with the common mode in this area；
Those skilled in the art can make various deformation within the scope of the claims or amendment make some simple deductions, deformation or
Replacing, this has no effect on the flesh and blood of invention.
