Description
Technical field
The utility model is related to voice coil technical fields, and in particular to the voice coil of coiling inside and outside a kind of rectangular line.
Background technology
With the promotion of quality of life, people the sound quality of loud speaker is required to come it is higher, and voice coil be in loud speaker not
The element that can lack.Coil on traditional voice coil is formed using common section for circular conducting wire coiling, this line
Type is offline to form a subtriangular gap between line, and the presence in this gap influences whether sound quality.And tradition
Voice coil in coil working when fever it is apparent, heat dissipation effect is poor.
Therefore, gap is small between a kind of line being needed in industry, the coil of good heat dissipation effect.
Invention content
In order to overcome shortcoming and defect in the prior art, the purpose of this utility model is to provide a kind of rectangular lines
The voice coil of coiling.
To achieve the above object, the utility model uses following scheme.
A kind of voice coil of rectangular line coiling, including skeleton and coil;The coil includes exterior loop and interior loop, exterior loop
It is close to skeleton outer wall, interior loop is close to inboard wall of skeleton, and interior loop is formed with exterior loop by same root conducting wire coiling;The conducting wire
Section to be rectangular.
Further, skeleton is enclosed by sheet is rolled into cylindric, and there are the gaps connected for inner-outer coil.
Further, skeleton surfaces externally and internally is equipped with the glue of curing coil.
Further, the number of turns of exterior loop is identical with the number of turns of interior loop.
Further, coil draws at least two electrodes.
Further, two electrodes are separated, and be fixed on coil by insulating layer.
Further, inboard wall of skeleton and outer wall at least one layer line circle of coiling.
The beneficial effects of the utility model:A kind of voice coil of rectangular line coiling is provided, ratio is contacted to obtain between conducting wire and conducting wire
It is relatively close, the gap between line and line is greatly reduced, improves conductor cross-section utilization rate;While inner ring has with outer ring and air
The face being in direct contact, improves heat dissipation effect well.
Description of the drawings
Fig. 1 is the cross-sectional view of the utility model embodiment.
Fig. 2 is the cross-sectional view of the utility model lattice coil.
Specific embodiment
For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and attached drawing further
Explanation, the content that embodiment refers to not is restriction to the utility model.
As shown in Figure 1, inside and outside a kind of rectangular line coiling voice coil, including skeleton 1 and coil;The coil includes exterior loop
3 and interior loop 2, exterior loop 3 be close to 1 outer wall of skeleton, interior loop 2 is close to 1 inner wall of skeleton;The interior loop 2 is with exterior loop 3 by same
A piece conducting wire coiling forms;The section of the conducting wire is rectangular.
The coil of traditional round conductor coiling, line and line are all that line contacts between line and skeleton, the utilization of conductor cross-section
Rate can form larger gap than relatively low.And use coil of the section for rectangular conducting wire coiling, line and line, line and skeleton it
Between be face contact, effectively reduce remaining gap, improve the utilization rate of conductor cross-section.And it can hold in identical space
The number of turns of rectangular line coiling received is more than the number of turns of round wires coiling, optimizes the duty ratio of coil so that in magnetic field force transfer process
Efficiency increases, and then achievees the purpose that improve voice coil sound quality.Meanwhile the pitch of the laps inside and outside skeleton 1, there are one faces and sky for Internal and external cycle
Gas is in direct contact, and increases heat dissipation area, therefore heat-sinking capability also increases.Moreover, pass through inner-outer coil and rectangular line coiling
It is combined, conductive area increases in coil, can allow through larger electric current, is conducive to improve power.
In the present embodiment, before non-coiling in the form of sheets, sheet framework is first rolled into skeleton 1 by when coiling round interior loop
It is cylindric, and there are the line gaps connected for inner-outer coil.Interior loop 2 with exterior loop 3 is formed by same root conducting wire coiling
, when 2 coiling of interior loop reaches a fixing turn, can by skeleton 1 there are gap lay out skeleton outer surface, carry out exterior loop
3 coilings.
In the present embodiment, 1 surfaces externally and internally of skeleton is equipped with the glue of curing coil.When reaching certain high temperature, glue
Water cure coil, makes coil molding.
In the present embodiment, the number of turns of exterior loop 3 is identical with the number of turns of interior loop 2.
In the present embodiment, the coil of 1 inside and outside wall coiling of skeleton is at least one layer.
In the present embodiment, coil draws two electrodes, and is equipped with the insulating layer of one layer of package coil on the electrode, by exhausted
Electrode is fixed on coil by edge layer.
In the present embodiment, 1 inner and outer wall of skeleton at least one layer line circle of coiling.As shown in Fig. 2, 1 inner wall of skeleton and outer
Wall two layers of coil of equal coiling.In addition, the number of plies of 1 inner and outer wall coiling of skeleton can differ.
In the present embodiment, when the voice coil of rectangular line coiling makes, inner-outer coil is by same root conducting wire coiling.First fix one
The skeleton 1 of sheet when coiling interior loop reaches a fixing turn, is fitted in the outer layer of interior loop 2 by electrode, coiling interior loop 2,
It is cylindrical, and there are certain intervals.Conducting wire lays out 1 outer surface of skeleton by gap, carry out 3 coiling of exterior loop to and interior loop
2 number of turns are identical.Then it will start fixed electrode to arrange to the surface of outside coil, be fixed with insulating layer.Draw again after spaced apart
Go out another electrode, then fixed with insulating layer, be finally molded product hot setting.
More than content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes, the content of the present specification should not be construed as in specific embodiments and applications
Limitation to the utility model.
