Description
Technical field
This utility model relates to a kind of coil and applies the speaker of this coil, more particularly, it relates to a kind of silver copper-clad coil and
Apply its speaker.
Background technology
Speaker is the most common a kind of electro-acoustic transducer device, and the most common speaker has moving-coil type and moving iron type loud-speaker.
Whether coil-moving speaker or moving iron type loud-speaker, coil is all indispensable driving element, is passed through in coil
Alternating current, coil will produce alternating magnetic field, utilizes this electromagnetic principle to realize electroacoustic conversion, so that speaker sends sound
Sound.At present, the coil of speaker is all made by copper cash, and copper cash has good electric conductivity, and price is relatively low, therefore copper
Line becomes the good wire rod making loudspeaker coil.
But, along with people are more and more higher to the requirement of speaker quality, people are in terms of the structure of speaker and material etc.
All it is made that a large amount of improvement, makes the quality of speaker be increased dramatically, produce a lot of high-grade audio amplifier and earphone etc..But
The coil of major part speaker still uses copper cash to make, and the electric conductivity of copper cash is not best, if can find more preferably
Material make coil, it is possible to promote further the quality of speaker；It will be appreciated that the electric conductivity of silver is in metal material
Best, but silver is a kind of important noble metal, price is higher, therefore uses silver wire to make coil, and its cost is the highest,
Cause the use demand being difficult to meet ordinary consumer.
Summary of the invention
1. utility model to solve the technical problem that
The purpose of this utility model is to overcome existing loudspeaker coil above shortcomings, it is provided that a kind of silver copper-clad coil and should
With its speaker, use the technical solution of the utility model, utilize silver copper-clad wire producing coil, take full advantage of wire and exist
Kelvin effect under alternating current effect, has given full play to the electric conductivity of the silver being positioned on surface, has further improved speaker
Tonequality, and reduce the cost of coil.
2. technical scheme
For reaching above-mentioned purpose, the technical scheme that this utility model provides is:
A kind of silver copper-clad coil of the present utility model, this coil is entwined by the silver-colored copper-clad wire being coated with insulating barrier, institute
The silver-colored copper-clad wire stated includes copper inner core and the silver-colored integument being wrapped on copper inner core.
A kind of speaker of the present utility model, applies above-mentioned silver-colored copper-clad coil.
3. beneficial effect
The technical scheme using this utility model to provide, compared with existing known technology, has the advantages that
A kind of silver copper-clad coil of the present utility model and apply its speaker, utilizes silver copper-clad wire producing coil, makes full use of
Wire Kelvin effect under alternating current effect, has given full play to the electric conductivity of the silver being positioned on surface, has further improved
The tonequality of speaker, and reduce the cost of manufacture of coil.
Accompanying drawing explanation
Fig. 1 is the conductive wire cross-section structural representation of a kind of silver copper-clad coil of the present utility model.
Label declaration in schematic diagram:
1, copper inner core；2, silver integument；3, insulating barrier.
Detailed description of the invention
For further appreciating that content of the present utility model, in conjunction with accompanying drawing, this utility model is described in detail.
Shown in Fig. 1, a kind of silver copper-clad coil of the present utility model, this coil is by the silver-colored copper-clad being coated with insulating barrier 3
Wire is entwined, and silver copper-clad wire includes copper inner core 1 and the silver-colored integument 2 being wrapped on copper inner core 1.
Below in conjunction with embodiment, the utility model will be further described.
Embodiment
As it is shown in figure 1, a kind of silver copper-clad coil of the present embodiment, this coil is by the silver-colored copper-clad wire being coated with insulating barrier 3
Being entwined, silver copper-clad wire includes copper inner core 1 and the silver-colored integument 2 being wrapped on copper inner core 1.A kind of silver of the present embodiment
Copper-clad coil, can use as the coil of moving-coil type or moving iron type loud-speaker, and insulating barrier 3 material can be common polyester, poly-
Urethane and polyimides etc., silver integument 2 can use the techniques such as plating to be attached on copper inner core 1, the silver-colored copper-clad in the present embodiment
The shape of cross section of wire is circular, naturally it is also possible to use flat, square equal cross-section.When being passed through alternating current in coil,
In the cross section of winding wire, the marginal portion electric current density of wire is big, and core electric current density is little (i.e. " Kelvin effect ",
Also referred to as " kelvin effect "), and it is electric conductivity extraordinary silver integument 2 in the marginal portion of winding wire, gives full play to
The electric conductivity of silver, further improves the tonequality of speaker；And the core of wire is copper inner core 1, this copper inner core 1
Also there is preferable electric conductivity, and cost is relatively low, reduce the cost of manufacture of coil, be therefore more prone to by ordinary consumption
The favor of person.
The present embodiment also discloses a kind of speaker, the above-mentioned a kind of silver copper-clad coil of this loudspeaker applications, make speaker
Tonequality is purer, significantly improves the performance of speaker, and makes speaker have relatively low cost, meets ordinary consumer
Demand.
A kind of silver copper-clad coil of the present utility model and apply its speaker, utilizes silver copper-clad wire producing coil, makes full use of
Wire Kelvin effect under alternating current effect, has given full play to the electric conductivity of the silver being positioned on surface, has further improved
The tonequality of speaker, and reduce the cost of manufacture of coil.
Below being schematically described this utility model and embodiment thereof, this description does not has restricted, shown in accompanying drawing
Be also one of embodiment of the present utility model, actual structure is not limited thereto.So, if this area is common
Technical staff is enlightened by it, in the case of creating objective without departing from this utility model, without creatively designing and this technology
Frame mode that scheme is similar and embodiment, all should belong to protection domain of the present utility model.
