Go out, suspension element 106 has substantially rectangular profile entirely around SRS 104.Typically, suspension element 106 is by portion
Divide or side 206A, 206B, 206C and 206D are formed, is connected with 202D by turning 202A, 202B, 202C or with its other party
Formula engages.Side 206A and 206C can be substantially straight and parallel to each other.For example, side 206A and 206C can respectively have
It is parallel to the length dimension (L of the longitudinal axis 204A and 204C as shown in the figure1).In this respect, side 206A and 206C is herein

Say the region or part of the suspension element 106 of each axis intersection in axis 204A to 204D.In some embodiments, axis 204A
It can be perpendicular to axis 204B and 204D with 204C so that right angle or 90 degree of angle are formed at their crosspoint, as schemed institute
Show.As previously described, because these 90 degree angles, when SRS 104 vibrates, turning 202A to 202D can be subjected to especially multiple
Miscellaneous deformation behaviour, this then causes the stress in these regions to increase.These complicated changes are discussed referring now to Fig. 3 and Fig. 4
Shape feature.
Representative, Fig. 3 is the enlarged view at representative turning 202, and Fig. 4 is the turning with reference to described in figure 3
The schematic diagram of deformation.In particular, the amplification turning view of Fig. 3 shows that it is considered as peak and/or central point 302 to have
And curve around object turning 202 relative to the corresponding circumference (c) and radius (r) for putting 302.During operation, when circular
When object turning 202 is moved up and down along z-axis (for example, z-axis as shown in Figure 4), the peak and/or central point 302 at turning 202 by
To the tension force effect in the radial direction along radius (r), and want circumferentially (c) towards or away from point 306 shown in radius
Center movement (x-axis for example, as shown in figure 4).
More particularly, as shown in figure 4, in resting position, suspension element 106 has radius (r) and circumference (c), wherein
Shown circumferential point (c) corresponds to peak 302 shown in Fig. 3.When suspension element 106 is as SRS 104 and voice coil 110 are towards magnetic
When body component 114 (also referred to as inlet wire direction) is moved and moved down along z-axis, suspension element 106 is wanted to reduce radius (r1)
(for example, point 302 is moved towards the central point 306 in Fig. 3) and circumference (c1).In addition, when suspension element 106 is with SRS 104
When being moved up along z-axis far from (also referred to as outlet direction) movement of magnet assembly 114 with voice coil 110, suspension element 106 is thought
Want increased radius (r2) (for example, point 302 is moved far from central point 306) and circumference (c2).It can be seen that from the schematic diagram of Fig. 4 quiet
Only radius (r) and downward radius (r1) radius change between (for example, access location) is less than static radius (r) and upward radius
(r2) radius change between (for example, outgoing line position).
These radially and/or circumferentially change geometrically, is especially introducing stress in a circumferential direction around object,
Maximum stress is along the maximum stress path for passing through turning.Based on selected material (there is specific elasticity), turn
Angle square cun and maximum deflection or offset, can be used standard finite meta analysis to calculate maximum stress path or maximum stress line.It answers
When further understanding, maximum stress path mentioned in this article or maximum stress line are calculated during manufacturing around object
, therefore be also to be calculated before forming " arch " shown in FIG. 1 or " rolling shape " region.In other words, it is to be based on
What flat Microspeaker was calculated around object surface.However, for Microspeaker, even if being formed " shape should be rolled "
After region, although having additional curvature, maximum stress region still can be described as the relatively straight line across turning.
It is contemplated, however, that in other embodiments, slight curving maximum stress line (as shown in dotted line 304) can be used to show
Go out the maximum stress region.For example, being sized to be used for there is " rolling shape " or " arch " region around object and be more than
In the case of the circular object (for example, the distance with bigger between interior comer edge and outer comer edge) of Microspeaker, most
Big line of tension can be slight curving.It will be appreciated, however, that even if in size change and the bending of maximum stress line or with its other party
Formula deviates in the case of straight line (as shown in the figure), and ripple still should be perpendicular to maximum stress line.
In this respect, it can be defined in various ways by the physical location in the maximum stress region shown in line 304.For example,
For Microspeaker, the maximum stress path at suspension element turning 202 or maximum stress line 304 can be defined as across turning
The central point 302 at angle and the line of tension for being parallel to and offsetting from the line 310 tangent with the inner arcuate surface at turning 202 308.
For example, central point 302 can be defined as the region among the inward flange and outer edge at the turning of radius (r) 202.In addition, by
The tangent line 310 for being parallel to turning 202 that can be as shown in the figure in maximum stress path or maximum stress line 304, therefore maximum stress
The tangent line that path or maximum stress line 304 are also referred to as deviated relative to turning inner arcuate surface 308 herein.This
Outside, from figure 3, it can be seen that maximum stress path or maximum stress line 304 also can be perpendicular to the diagonal lines or radial axle at turning 202
312, and can be deviated from inner arcuate surface 308, therefore can be also defined relative to radial axle 312.For example, maximum stress
Path or maximum stress line 304 can be defined as across turning 202 and the line that intersects with radial axle 312, and in some cases
Under divide the radial axle 312 (or diagonal line) at turning 202 equally with 90 degree of angle.
These ambient stress along maximum stress path or maximum stress line 304 are non-linear behaviors and generate feeling of fatigue
Main cause.In order to reduce this stress and the then generation of reduction non-linear behavior and feeling of fatigue, will be answered relative to the maximum
There are multiple ribs of specific orientation or ripple to be introduced into suspension element turning in power region.In particular, turning now to Fig. 2, often
A turning 202A to 202D includes multiple ribs or ripple 208.Rib or ripple 208 can be along the longitudinal direction from the 202A to 202D of turning
The inward flange 106A at each turning extend to outer edge 106B.Rib or ripple 208 can be limited in their own turning,
So that the ripple 208 in adjacent corners is not overlapped.For example, the ripple 208 in their own turning 202A to 202D can turn
It is spaced apart by non-ripple area 210 in angle 202A to the region of the side 206A to 206B between 202D.As discussed herein,
Each turning in the 202A to 202D of turning may include any amount of ripple for being suitable for improving linear behavior and feeling of fatigue.
The specific orientation and structure of ripple are discussed referring now to Fig. 5 to Fig. 8.Fig. 5 shows putting for the turning 202B of Fig. 2
Big plan view from above.Can be seen that turning 202B from this view includes the more of the entire width dimensions (W) across turning 202B
A ripple 208.In other words, from the inward flange 106A of turning 202B to outer edge 106B.Each ripple 208 can have relative to
The identical orientation of maximum stress path or maximum stress line 304 (and tangent line 310).For example, each ripple 208 can perpendicular to
Maximum stress path or the side of maximum stress line 304 upwardly extend.More particularly, from fig. 5, it can be seen that each ripple 208
With the length axis intersected with maximum stress path or maximum stress line 304 with 90 degree of angles or size (L).In addition, such as preceding institute
It states, in the case where maximum stress path or maximum stress line 304 are parallel to tangent line 310, the length axis or size of ripple 208
(L) can also be defined as upwardly extending in the side vertical with tangent line 310 or it is vertical with tangent line 310 or with 90 degree of angle with
Tangent line 310 intersects.In addition, the diagonal line or radial direction of maximum stress path or maximum stress line 304 and tangent line 310 and turning 202
Axis 312 intersects.Diagonal line or radial axle 312 can be considered as extending in diagonal line or in the radial direction and dividing turning 202 equally
Axis, as shown in Figure 5.In some embodiments, maximum stress path or maximum stress line 304 and tangent line 310 can be with 90
The angle of degree intersects with radial axle 312.Therefore, in some embodiments, the length dimension (L) of ripple 208 can be also described
For the line (for example, line 304 or line 310) intersected perpendicular to the radial axle 312 with turning 202.In addition, in some embodiments
In, ripple 208 can be substantially straight structure that is parallel to each other and/or being parallel to radial axle 312.In other words, wave
Line 208 will not be along length dimension (L) complications, bending, bending or otherwise with flexure configuration.Further, it should
, it is noted that although maximum stress path or maximum stress line 304 are shown as straight line, it can slight curving and wave
Line 208 can be perpendicular to the slight curving line.
It has been found that as described herein, when ripple 208 at each corner rather than another angle perpendicular to most
When big line of tension 304 is orientated, ripple 208 more uniformly absorbs circumferential direction and radial deformation during membrane displacement.This is then helped
And reduction circular object feeling of fatigue at any time linear in recovery.For example, Fig. 6 shows and is orientated perpendicular to maximum stress line 304
Ripple 208 and the ripple 602 being orientated with the angle (for example, obtuse angle or acute angle) different from 90 degree relative to maximum stress line
Enlarged view.From fig. 6, it can be seen that the ripple 208 of vertical orientation is relatively evenly absorbed along length dimension (L) by object
Radially and/or circumferentially change and deformation (for example, shrink) caused by power (being shown by arrow 604).On the contrary, just non-perpendicular take
To ripple 208 for, these power 604 so that ripple 208 along length dimension almost in a distorted way anisotropically deform (example
Such as, it shrinks).Compared with relatively uniform deformation, such ripple deformation is being absorbed along radius and/or the circular object of circumference
It is ineffective when change, then in resisting fatigue sense nor so effectively.
Other than the orientation of ripple 208, for the reduction for realizing feeling of fatigue and the improved linearity, each turning 202A
Ripple 208 in each turning in 202D it is continuous and smooth also critically important.In order to illustrate this aspect, Fig. 7 is shown
A series of amplification cross-sectional side view of ripples in each turning.Typically, from this view, it can be seen that ripple 208 by
A series of alternate ribs or ridge 702A, 702B, 702C, 702D, 702E, 702F and 702G and ditch 704A, 704B, 704C,
704D, 704E and 704F are formed.Each in alternate ridge 702A to 702G and ditch 704A to 704F is referred to alternatively as ripple, and
And can be considered continuous because they have be directly connected to or spatial relationship and do not have between adjacent structure space or
Gap.For example, the geometry of ripple 208 can be defined as continuous second derivative, and every other derivative
All it is continuous.In this respect, ripple 208 is also considered as smooth structure, and is transitioned into next wave in a ripple
There is no any lofty bending or turning at line.In other words, the peak that is formed by ridge 702A to 702G and ditch 704A to 704F and
Paddy is bending, or is formed by making line continuous bend and have radius, as previously described.Though it will be further understood that
Seven ridge 702A so are shown to 702G, but may include any amount of ridge or ripple around object turning.In addition, each surround
Object turning may include the ripple of identical quantity or different number.Although in addition, it should be understood that be described in detail one it is specific
Circular object turning, i.e. turning 202B, but each suitable for turning 202A, 202C and 202D of description of turning 202B
Turning.Therefore, all turning 202A to 202D will have perpendicular to maximum stress line and continuous ripple 208.
