Change, the machinery decay of opposite linear can be also provided for suspension system, the damping effect of loudspeaker is finally then shown as.
The ins and outs of the structure for the voice coil loudspeaker voice coil that the loudspeaker that the utility model embodiment is provided is used refer to foregoing
Embodiment related content, will not be repeated here.
In order to preferably explain the utility model, refering to Fig. 3, for raising one's voice using the utility model voice coil loudspeaker voice coil and common voice coil loudspeaker voice coil
Device Qms (mechanical quality factor) comparison diagram, in the utility model embodiment, " Coil in/out " are represented Fig. 3 abscissas
Be " the up/down displacement of voice coil loudspeaker voice coil relative equilibrium position ", it is negative to offset up just, to offset downward；In ordinate " Qms "
What " Qm " was represented is " mechanical quality factor ", and " s " represents loudspeaker unit " speaker ", and Qms implication is " loudspeaker unit
Quality factor "；According to the existing Qm on mechanical quality factor definition, Qm values are used to reflect certain inverting element or system
Mechanical loss size, mechanical loss is smaller, and Qm values are bigger；Mechanical loss is bigger, and Qm values are smaller；Implement in the utility model
In mode, mechanical loss is mainly shown as the damping i.e. loudspeaker of loudspeaker generation for the energy for overcoming interior friction and consuming
Amount, that is to say, that Qms value is bigger, and mechanical loss is smaller, and the damping of the performance of loudspeaker is smaller；So can from figure
To draw a conclusion：
1st, the offset according to the voice coil loudspeaker voice coil of abscissa in loudspeaker Inner up/down can be drawn, when voice coil loudspeaker voice coil motion amplitude is consistent
When (i.e. Y value is consistent), the loudspeaker B of voice coil loudspeaker voice coil of the present invention is employed than being consumed using the loudspeaker A of general voice coil loudspeaker voice coil
Energy it is more, damping is more excellent；
2nd, according to the comparison of ordinate Qms numerical value, abscissa be voice coil loudspeaker voice coil displacement it is constant in the case of, using this practicality
Mechanical damping of the loudspeaker B of the new voice coil loudspeaker voice coil mechanical damping than the loudspeaker A using common voice coil loudspeaker voice coil is big, and damping increase
Reach 20%.
2 conclusions more than, and actual experiment data are combined, the voice coil loudspeaker voice coil that the utility model is used can be effectively to raising
The mechanical damping of sound device is controlled, and obvious to the damping increase of loudspeaker.
In summary, the loudspeaker that the utility model embodiment is provided, by using voice coil loudspeaker voice coil described in the utility model, energy
Make its export the rear delay characteristics of tonequality more preferably, be not in excessive lingering sound and sound parsing power is high, sound is fuller.
The utility model embodiment also provides a kind of method for manufacturing the voice coil loudspeaker voice coil described in above-described embodiment, new for this practicality
The manufacture method for the voice coil loudspeaker voice coil that type embodiment is provided, is the manufacturing step flow chart of the utility model voice coil loudspeaker voice coil, in this reality refering to Fig. 4
With in new embodiment：
S1, makes skeleton, as needed selection material cut-parts, gluing, while being voice coil loudspeaker voice coil coil 2 and damping on skeleton 1
Mark is carried out in the coiling position of control unit 3, glue used should be can high-temperature baking adhesion, material should be completely covered in glue
Surface；
S2, coiling voice coil loudspeaker voice coil coil and connection damping control part, by tool by the rolled forming of skeleton 1, make on skeleton
To be preferred, the skeleton 1 can be rolled into cylindrical shape；According to actual needs, the skeleton 1 can also be rolled into other shapes,
Such as track type, is not only limited in cylindrical shape；Refering to Fig. 5, the speech coil framework completed state provided for the utility model embodiment
Figure, after skeleton is rolled into cylindrical shape, the first of the position that the two ends of skeleton 1 are mutually connected 12 does not engage at 11 and second, and protects
0.3 millimeter to 0.5 millimeter gap is held, to cause skeleton 1 when being moved in loudspeaker with certain deformation and ductility, it is to avoid
After heated, the skeleton 1 is deformed because of expansion；
The coiling position of S3, high-temperature baking, voice coil loudspeaker voice coil coil 2 and damping control part 3 is with reference to the mark position in S1；As
It is preferred that, the selection of material of damping control part 3 should meet conductive non-magnetic attribute, still, if the material used is conduction
And magnetic conduction, then material therefor outer covering magnetic masking layer or do other magnetic screens processing come make damping control part not by
What external magnetic field influenceed can also；Damping control part 3 should be fitted close with skeleton 1 not to be loosened, in socket damping control part 3
Before, the first gluing of their inwall faying face, glue used should be able to high-temperature baking adhesion, and glue can be covered with S1 middle skeletons surface
Form strong bond；If being used as damped part 3 using becket in S2, then can be one-time formed loop configuration,
Can be strip material be rolled into after annular mechanism again will head and the tail it is integrally welded；If being used as damping control portion using wire coil
Part 3, then it should be using being wound on skeleton 1 with the identical method of voice coil loudspeaker voice coil coil 2, and tack wire rod, line can be used in wire coil
Material top layer glue should be able to cover glue with the surface of S1 middle skeletons 1 and form firm coiling, can high-temperature baking adhesion, wire coil coiling
It is afterwards that wire rod head and the tail are integrally welded and ensure that wire coil can form close access；Preferably, at 180 DEG C to 200 DEG C
Under baking temperature, complete skeleton 1 and voice coil loudspeaker voice coil coil 2, skeleton 1 are bonding with damping control part 3, according to actual conditions, can adopt
Preferable adhesive effect is reached with different baking temperatures；
S4, the then bright and beautiful silk thread on skeleton, the lead-out wire of voice coil loudspeaker voice coil coil 2 and bright and beautiful silk thread 4 are connected together；So that bright and beautiful silk thread
Circuit pathways, then then bright and beautiful silk thread 4 on skeleton 1 are formed between 4 and voice coil loudspeaker voice coil coil 2, specifically, by the bright and beautiful silk thread 4 with
The lead-out wire of the voice coil loudspeaker voice coil coil 2 mutually weld that terminate on the skeleton 1, optionally, and the protection of upper Protection glue is described
The position of bright and beautiful silk thread 4 and the skeleton 1 mutually then.
In summary, the voice coil loudspeaker voice coil manufactured by the manufacture method of voice coil loudspeaker voice coil provided in an embodiment of the present invention, can be to loudspeaker
Mechanical damping control effectively, and does not influence the other performance of loudspeaker, while improving the output tonequality of loudspeaker.
The utility model is not limited to above-mentioned embodiment, and other are any without departing from Spirit Essence of the present utility model and original
Change done down, modification, replacement, combination, simplification are managed, equivalent substitute mode is should be, is all considered as being included in this practicality
Within new protection domain.
