＜1. about sprung parts 〉
(1) about sprung parts 10A
The sprung parts 10A of expression present embodiment among Fig. 1.This sprung parts 10A is the parts that support magnetic circuit portion 130 (referring to Figure 12, Figure 13), and is the parts that this magnetic circuit portion 130 applied active force.Sprung parts 10A has outer frame 20A, interior protuberance 30A, top extension 40A and support portion 50A.In addition, sprung parts 10A forms as material with the rubber-like metal.But in order to reduce the influence from magnetic circuit etc., sprung parts 10A does not adopt the ferromagnetism material but is formed by the material a little less than the magnetic.As such material stainless steel is arranged, as the material of bringing into play better elastic SUS301 is for example arranged.
In addition, extension 40A in top is from the part of interior protuberance 30A towards end side extension longitudinally.As shown in Figure 1, top extension 40A from interior protuberance 30A respectively towards distolateral and another distolateral extension.Therefore, in Fig. 1, there are four altogether in top extension 40A.In addition, as shown in Figure 2, top extension 40A with along with from interior protuberance 30A towards support portion 50A and gradually the mode of trend top (Z 1 side) be designed to ramped shaped.In addition, top extension 40A and interior protuberance 30A are corresponding to the cantilever portion described in claims.
In addition, shown in Fig. 3 (A), the ramp shaped of top extension 40A is designed to linearity in the time of can forming side-looking, and the shape that is bent with respect to the boundary member of interior protuberance 30A and support portion 50A.But shown in Fig. 3 (B), the ramp shaped of top extension 40A is designed to curve-like in the time of also can forming side-looking.Under the situation of Fig. 3 (B), top extension 40A is designed to along with near interior protuberance 30A or support portion 50A and the angle that forms with respect to directions X diminishes.
In addition, support portion 50A is mounted in the part in the magnetic circuit portion 130.One of extension 40A is distolateral distolateral with another above this support portion 50A was arranged at respectively.Support portion 50A is designed to the top extension 40A in laterally (Y-direction) separation is coupled together to each other.In addition, based on utilizing support portion 50A to support the relation of magnetic circuit portion 130, support portion 50A is designed to wideer than top extension 40A.
In the sprung parts 10A of above such structure, support portion 50A is by top extension 40A and away from interior protuberance 30A.And top extension 40A is designed to ramped shaped.Therefore, can make support portion 50A be positioned at top (Z1 side) with respect to outer frame 20A, can guarantee the stroke of magnetic circuit portion 130 when above-below direction (Z direction) is mobile thus.
But in sprung parts 10A, top extension 40A is that fulcrum is out of shape with interior protuberance 30A, and support portion 50A carries out circular-arc motion according to its distortion.Therefore, with respect to magnetic circuit portion 130, support portion 50A is designed at directions X mobile.
In addition, in sprung parts 10A, the ramp shaped of extension 40A is under the situation of linearity such shown in Fig. 3 (A) up, can easily make this sprung parts 10A by the pressure processing of metallic plate, thereby can improve the productivity ratio of sprung parts 10A.In addition, in sprung parts 10A, the ramp shaped of extension 40A is under curvilinear situation such shown in Fig. 3 (B) up, can prevent from forming the situation of the such stress raiser of sweep among Fig. 3 (A) for example.
In addition, sprung parts 10A shown in Figure 1 also can use with following such form.That is, as shown in Figure 4, the 22A of short-movie portion along Y-direction among the outer frame 20A is contacted with bonnet 110 with chamfered section 23A, perhaps they are configured in respect to bonnet 110 near and relative position on.On the other hand, the 21A of lengthy motion picture portion is designed to along with tending to the ramped shaped of top (Z 1 side) gradually towards vertical center side from the root portion with respect to chamfered section 23A.That is to say that the 21A of lengthy motion picture portion and top extension 40A similarly are the different structure of height and position between with respect to the root portion of chamfered section 23A and interior protuberance 30A, go up the stroke of mobile usefulness at above-below direction (Z direction) in order to guarantee magnetic circuit portion 130.By like this, sprung parts 10A can guarantee the stroke of magnetic circuit portion 130 when above-below direction (Z direction) is mobile more fully.
(2) about sprung parts 10B
The expression sprung parts 10B dissimilar with sprung parts 10A among Fig. 5.This sprung parts 10B with outer frame 20B, interior protuberance 30B, top extension 40B, rotating part 60B and support portion 50B as main structural detail.
In addition, the interior protuberance 30A of interior protuberance 30B and above-mentioned sprung parts 10A is similarly interior side-prominent towards what surrounded by outer frame 20B.But interior protuberance 30B and each top extension 40B is designed to independently state accordingly, rather than as the interior protuberance 30A of sprung parts 10A by the structure of extension 40A dual-purposes above two.Therefore, the interior protuberance 30B that is the interior protuberance 30B of X1 side and X2 side has the configuration in a little gap.
In addition, one of top extension 40B distolateral being connected on the interior protuberance 30B.And, among the extension 40B, there is the line part 41B from the distolateral linearly extension longitudinally of one up, also be connected with the oblique shape extension 42B that extends obliquely from line part 41B, and then tiltedly shape extension 42B is connected on the rotating part 60B.In addition, tiltedly shape extension 42B is designed to slightly parallel with chamfered section 23B.
In addition, linearly when the ramp shaped of top extension 40B can form the such side-looking of above-mentioned Fig. 3 (A), be curved shape in the time of also can shown in Fig. 3 (B), forming side-looking like that.
In the sprung parts 10B of above such structure, except the common action effect of the action effect that produces with above-mentioned sprung parts 10A, can also produce following such action effect.Namely, in sprung parts 10B, at support portion 50B when above-below direction (Z direction) is mobile, because support portion 50B is designed to shaped as frame and is installed in the magnetic circuit portion 130, therefore, not only produce the distortion along its bearing of trend in the distortion of top extension 40B, also produce the crooked such distortion of top extension 40B.Be described in detail, not only have the composition of directions X in the distortion of top extension 40B, also have the composition of Y-direction.That is, the oblique shape extension 42B of top extension 40B and line part 41B are out of shape with the state of distortion.Then, follow the distortion of such distortion by top extension 40B, support portion 50B can be with mobile at above-below direction (Z direction) to the repressed state of the movement of directions X with respect to magnetic circuit portion 130.
In addition, because interior protuberance 30B is the structure that independently arranges with respect to each top extension 40B, therefore, between the interior protuberance 30B of adjacency, there is a little distance.Therefore, compare with the support portion 50A of sprung parts 10A, it is flatly mobile at above-below direction (Z direction) that support portion 50B makes magnetic circuit portion 130 keep easily.That is, compare sprung parts 10A, in sprung parts 10B, can be suppressed at the situation that support portion 50B sidewinders.
(3) about sprung parts 10C
The dissimilar sprung parts 10C of expression and sprung parts 10A and sprung parts 10B among Fig. 6.This sprung parts 10C with outer frame 20C, interior protuberance 30C, the first top extension 40C1, return portion 70C, the second top extension 40C2 and support portion 50C as main structural detail.
In addition, in sprung parts 10C, only there is one in support portion 50C in the central portion office of vertical (directions X), and is designed to area greater than the support portion 50A among the sprung parts 10A.
In addition, as shown in Figure 6 and Figure 7, the first top extension 40C 1 is identical with the top extension 40A of sprung parts 10A, and one distolateral (X1 side) is connected on the interior protuberance 30C, but another of this first top extension 40C1 distolateral (X2 side) is connected on the return portion 70C.Then, return portion 70C is connected on the second top extension 40C2, and still, this second top extension 40C2 and the first top extension 40C1 are extension inversely, and one distolateral (X1 side) is connected on the 50C of support portion.That is, via interior protuberance 30C, the first top extension 40C1, return portion 70C and the second top extension 40C2 path till the 50C of support portion, be designed to zigzag from the 21C of lengthy motion picture portion.
In addition, the first top extension 40C1 is designed to along with tending to the ramped shaped of top (Z1 side) gradually towards return portion 70C from interior protuberance 30C, and the second top extension 40C2 also is designed to along with tending to the ramped shaped of top gradually towards support portion 50C from return portion 70C.By like this, in sprung parts 10C, the support portion 50A that the height and position of support portion 50C becomes and is higher than sprung parts 10A.Thus, in sprung parts 10C, the stroke of mobile usefulness is gone up greater than sprung parts 10A at above-below direction (Z direction) by magnetic circuit portion 130.
In addition, the ramp shaped of the first top extension 40C1 and the second top extension 40C2, linearly in the time of can forming the such side-looking of above-mentioned Fig. 3 (A), be curved shape in the time of also can shown in Fig. 3 (B), forming side-looking like that.
In the sprung parts 10C of above such structure, except the common action effect of the action effect that produces with above-mentioned sprung parts 10A, can also produce following such action effect.Be designed to zigzag from the 21C of lengthy motion picture portion to the part between the 50C of support portion.In other words, to be designed to current collection arc for sprung parts 10C.Therefore, can guarantee that support portion 50C is big at the above-mentioned sprung parts 10A of stroke ratio, the 10B of the last mobile usefulness of above-below direction (Z direction).
In addition since sprung parts 10C to be designed to current collection arc, therefore, do not have unnecessary distortion.And then, owing in sprung parts 10C, there is notch 24C, therefore, when utilizing pressure processing to come die-cut metallic plate, can form the position of support portion 50C than the high such three-dimensional shape in the position of outer frame 20C.Namely, under the situation that does not have notch 24C, if the first top extension 40C 1 and the second top extension 40C2 extended than unfertile land or with operations such as the first top extension 40C 1 and the second top extension 40C2 install separately, be difficult to then realize that the position of support portion 50C is higher than the structure of outer frame 20C.But, owing in sprung parts 10C, there is notch 24C, therefore, if adjust the interval of this notch 24C is narrowed down, the position that then can easily realize support portion 50C is with respect to the high such stereochemical structure of outer frame 20C.
In addition, in sprung parts 10C, can make the length in the path that is constituted by the first top extension 40C1 and the second top extension 40C2 greater than top extension 40A, 40B.Therefore, on the above-below direction (Z direction) only under the situation of mobile phase with stroke, can dwindle the angle that the first top extension 40C1 and the second top extension 40C2 form with respect to outer frame 20C.By like this, can reduce the load to sprung parts 10C, thereby can seek the long lifetime of sprung parts 10C.
(4) about sprung parts 10D
The expression sprung parts 10D dissimilar with sprung parts 10A～10C among Fig. 8.But sprung parts 10D is and the similar type of sprung parts 10C.
This sprung parts 10D with outer frame 20D, interior protuberance 30D, the first top extension 40D1, return portion 70D, the second top extension 40D2 and support portion 50D as main structural detail, but, be with the difference of sprung parts 10C, in sprung parts 10D in protuberance 30D be positioned on such position away from vertical (directions X) central authorities such as chamfered section 23D.Thus, the slope direction of the first top extension 40D 1 and the second top extension 40D2 and sprung parts 10C are reverse.In addition, in sprung parts 10C, only there is one in support portion 50C in the central portion office of vertical (directions X), still, in sprung parts 10D, is support portion 50D and is arranged at the vertically structure at the two ends of (directions X) (having two altogether) respectively.
In addition, in structure shown in Figure 8, because interior protuberance 30D is connected on the chamfered section 23D, therefore, be almost non-existent state of this interior protuberance 30D.That is, not only have under the situation that the directions X composition also has the Y-direction composition at bearing of trend as chamfered section 23D, can adopt the structure of protuberance 30D in omitting.
In the sprung parts 10D of above such structure, except the common action effect of the action effect that produces with above-mentioned sprung parts 10C, can also produce following such action effect.
That is, as Fig. 8 and shown in Figure 9, in sprung parts 10D, the length of support on the directions X in being connected to of the first top extension 40D1 on the protuberance 30D (outer frame 20D) from, greater than the length of support among the sprung parts 10C from.Therefore, compare with the support portion 50C of sprung parts 10C, it is flatly mobile at above-below direction (Z direction) that support portion 50D makes magnetic circuit portion 130 keep easily.That is, compare sprung parts 10C, in sprung parts 10D, can be suppressed at the situation that support portion 50D sidewinders effectively.
(5) about sprung parts 10E (bonnet integral type)
The expression sprung parts 10E dissimilar with sprung parts 10A～10D among Figure 10.This sprung parts 10E (referring to Figure 11～Figure 13) be integrated this point, is the difference with above-mentioned sprung parts 10A～10D with respect to bonnet 110.In addition other structures of sprung parts 10E are identical with above-mentioned sprung parts 10D, therefore, omit the explanation of the each several part of sprung parts 10E.
More than the sprung parts 10E of such structure owing to be integrated with bonnet 110, therefore, can cut down the parts number of packages of multifunction oscillatory exciter 100.In addition, compare with the situation that this parts number of packages is not cut down, can reduce the man-hour of assembling usefulness by the parts number of packages of cutting down multifunction oscillatory exciter 100.
＜2. about having used the multifunction oscillatory exciter of sprung parts 〉
Next, the multifunction oscillatory exciter 100 that has used above-mentioned sprung parts 10 is described.Figure 11 is the stereogram of the outward appearance of expression multifunction oscillatory exciter 100, and Figure 12 is the exploded perspective view of multifunction oscillatory exciter 100, and Figure 13 is expression along the sectional side view of the A-A line of Figure 11 state after with 100 cuttings of multifunction oscillatory exciter.In addition, the stereogram of Figure 14 state that is expression when bottom surface side (below side) is observed multifunction oscillatory exciter 100.
In addition, in Figure 12, as an example of multifunction oscillatory exciter 100, represented to use the multifunction oscillatory exciter 100 of sprung parts 10D.But employed sprung parts 10 is not limited to sprung parts 10D in the multifunction oscillatory exciter 100, also can use the sprung parts 10 of any one type among above-mentioned sprung parts 10A～10D.In addition, as sprung parts 10, can also use with bonnet 110 to be integrated sprung parts 10E.Therefore, though in Figure 12 and Figure 13, illustrate sprung parts 10D, in the following description, do not distinguish sprung parts 10A～10E especially and describe.
