Since the method that the present invention reduces super-thin speaker distortion has adjusted reversed folding according to the result that Klippel is tested
Relative altitude between the medial surface and lateral surface of ring can adjust Kms to change position of the voice coil in magnetic circuit system
(x) (the mechanics stiffness of vibrational system is pliable inverse) is in the symmetrical of coil in (in voice coil) and coil out (outside voice coil)
Property and equilbrium position when movement, and then improve the non-linear of vibrational system, effectively reduce non-linear distortion, improve
The acoustical behavior of anti-corrugated rim loudspeaker enables loudspeaker to meet the design requirement of height and acoustical behavior simultaneously.
In conclusion the present invention reduce super-thin speaker distortion method solve loudspeaker in the prior art can not be same
When meet height and acoustical behavior design requirement the technical issues of, the present invention reduce super-thin speaker distortion method it is effective
The non-linear distortion for reducing anti-corrugated rim loudspeaker, enable loudspeaker to meet height simultaneously and the design of acoustics wanted
It asks.

Specific embodiment
With reference to the accompanying drawings and examples, the present invention is further explained.
The inside being related in this specification refers to that close to the side at Microspeaker center, outside refers to raises far from miniature
The side at sound device center；Refer to the direction for being equipped with vibrational system in the orientation being related in this specification, refers under orientation and be equipped with magnetic circuit
The direction of system.
As shown in Figure 1, a kind of super-thin speaker, including frame 20, the upper end of frame 20 are fixed with vibrational system, frame
20 lower end is fixed with magnetic circuit system 50.Vibrational system includes the basin with compound 10 that edge part is fixed on 20 upper surface of frame, compound
The middle part of basin 10 is combined with top dome 40 and voice coil 30, and the end of voice coil 30 is located in magnetic gap 52.Basin with compound 10 includes in being located at
The oscillating plate 14 that portion is combined with top dome 40 and voice coil 30, and it is fastened around the ring 12 of 14 periphery of oscillating plate, the side of ring 12
Edge is fixed in frame 20.In order to reduce the height of loudspeaker, the ring 12 of this loudspeaker is reversed ring, i.e. protrusion direction
Downwards, such structure also results in the poor linearity of vibrational system, non-linear mistake while effectively reducing speaker height
Very serious, for such situation, the present invention provides the methods that reflexed ring Nonlinear Distortion of Loudspeakers can effectively drop in one kind:
A method of super-thin speaker distortion being reduced, the method includes the following steps:
Klippel (sound analysis system) test is carried out to anti-corrugated rim loudspeaker first, obtains Kms (x) curve and Kms
Symmetry range (Kms symmetrical range) curve, the nonlinear situation of vibrational system is obtained according to this two curves；
Then the lateral surface of ring and the relative altitude of medial surface are adjusted according to this test result, adjustable Kms (x) exists
The equilbrium position when symmetry and movement of coil in and coil out reduces and adopts so as to improve the non-linear of vibrational system
With the non-linear distortion of the super-thin speaker of reflexed ring, the acoustical behavior of such loudspeaker is improved.
Citing below provides the embodiment party of two kinds of lateral surfaces that ring is adjusted according to test result and medial surface relative altitude
Formula:
The first, the medial surface of ring is adjusted to by the lateral surface lower than ring according to test result,
As shown in Fig. 2, the medial surface B of basin with compound 10a, ring 12a are slightly below lateral surface A, i.e. the difference in height of the two is small
In the thickness of ring material；
As shown in figure 4, the medial surface B " being lower than lateral surface A " of basin with compound 10c, ring 12c, the difference in height of the two is compared with Fig. 2
Shown in be preferably greater than equal to the thickness of ring material, but be less than the 1/2 of ring height greatly in embodiment.
Second, the medial surface of ring is adjusted to by the lateral surface higher than ring according to test result,
As shown in figure 3, the medial surface B ' of basin with compound 10b, ring 12b are higher than lateral surface A ', the difference in height of the two is preferred
For the thickness more than or equal to ring material, but it is less than the 1/2 of ring height；Difference in height both in present embodiment can also be small
In the thickness of ring material, i.e. medial surface B ' is slightly above lateral surface A '.
The method that the present invention reduces super-thin speaker distortion passes through the opposite of the medial surface and lateral surface for adjusting reflexed ring
It is highly effective to improve the non-linear of vibrational system, non-linear distortion is reduced, the acoustical behavior of loudspeaker is improved.
Above-described embodiment is only effective by the medial surface of adjusting reflexed ring and the relative altitude of lateral surface to the present invention
Improve the nonlinear technical solution of vibrational system for example, be not exhaustion, as long as by adjusting on the inside of ring
The relative altitude of face and lateral surface is fallen within the protection scope of the present invention in the method for reducing Nonlinear Distortion of Loudspeakers.Simultaneously
The structure of loudspeaker is not limited in above structure, and technical solution of the present invention is applicable to any anti-corrugated rim loudspeaker
In, those skilled in the art do not need to pay any creative work according to the description of above-described embodiment can be by skill of the invention
Art scheme is applied in the loudspeaker of other structures, therefore no matter whether the other structures of loudspeaker are same as the previously described embodiments, only
If equal to reduce the method for non-linear distortion of loudspeaker by the relative altitude for adjusting reflexed ring medial surface and lateral surface
It falls within the scope of protection of the present invention.
