Form the elastic bearing components 33,33 that constitute continuously from support foot 31 in the both sides of the directions X of supporting mass 30.
As depicted in figs. 1 and 2, the elastic bearing component of giving prominence to the outstanding elastic bearing component 33 of a side of directions X and the opposing party to directions X from support foot 33 33 is for clipping the structure that the Y-Z face faces with each other and claims.
Amplify shown in the expression like Fig. 4, elastic bearing component 33 has middle board 34.Of Fig. 3, middle board 34 forms from the last direction of sidepiece to the Z direction towards directions X of the support foot 31 of supporting mass 30 and is bent into the right angle.In Fig. 4, the length dimension of the Y direction of middle board 34 is represented by W.
In elastic bearing component 33, be provided with clamping part 35 to the position of the outside of directions X devices spaced apart from said middle board 34.As shown in Figure 3, on clamping part 35, form with said in the middle of the parallel maintenance board 35a of board 34 and with keep the crooked elasticity retention tab 35b of the opposed mode of board 35a.As shown in Figure 4, through keeping the fixedly board 12 of board 35a and elasticity retention tab 35b clamping framework 10.At this moment, keep board 35a and fixedly the inner surface 12a of board 12 connect airtight elasticity retention tab 35b and the fixedly outer surface 12b elasticity crimping of board 12, and clamping part 35 is fixed in fixedly board 12.
As shown in Figure 4, the outer surface 34a of middle board 34 is parallel each other with the inner surface 35c that keeps board 35a, between them, is provided with the first strain portion 36.The first strain portion 36 passes through to constitute the leaf spring material and the middle board 34 of supporting mass and keep board 35a integrally formed.
The first strain portion 36 has two distortion board 36a, 36b.Distortion board 36a, 36b form the length dimension band plate shape bigger than the width dimensions of Z direction that third direction is the Y direction.Variant part 36a, 36b form, and the thickness of slab direction is towards first direction (directions X), and width is the Z direction towards second direction, and length direction is the Y direction towards third direction.
The base portion of distortion board 36a is continuous via 36c of base curve portion and middle board 34, and the base portion of distortion board 36b is continuous with maintenance board 35a via the 36d of base curve portion.The front portion of distortion board 36a is continuous via the 36e of bent intermediate portion with the front portion of the 36b of distortion board.
The length direction of distortion board 36a and distortion board 36b is towards the Y direction, and therefore the thickness of slab direction, is to produce crooked deformation on the directions X at first direction mainly towards directions X, and its curvature direction is the Y direction.The bending center line of 36c of base curve portion and the 36d of base curve portion and the 36e of bent intermediate portion is the Z direction towards second direction, is to produce crooked deformation on the directions X at first direction mainly.
The first strain portion 36 is that directions X has first coefficient of elasticity ground and carries out strain through the crooked deformation separately of distortion board 36a, 36b crooked deformation and the 36c of base curve portion, 36d and the 36e of bent intermediate portion separately towards first direction.The first strain portion 36 is given to the required bending stress of the crooked deformation of first direction little, first coefficient of elasticity is smaller value.Through the deformation along directions X of the first strain portion 36, vibrating body 20 and the supporting mass 30 that carries it can vibrate to directions X.First eigentone of this moment is by the total quality and the decision of said first coefficient of elasticity of vibrating body 20 and supporting mass 30.Because first coefficient of elasticity is smaller value, therefore first eigentone is lower.
When first direction was the directions X vibration, its direction of vibration was the shear direction of the distortion board 38 of the formation second strain portion 39 at vibrating body 20.In addition, strain portion 39 and the first strain portion 36 to compare flexural rigidity enough big.Therefore, when first direction was the directions X vibration, the second strain portion 39 was indeformable basically at vibrating body 20 and supporting mass 30.
Is that the Z direction is when moving at vibrating body 20 and supporting mass 30 to second direction; Shearing force with respect to the distortion board 36a, 36b and the bend 36c that constitute the first strain portion 36,36d, the oriented width of 36e effect (Z direction); In addition, also effect has very little torsion.Make the first strain portion 36 make the first strain portion 36 enough big to the required power of directions X flexural deformation to shear direction and the required force rate of torsional direction distortion.That is, the first strain portion 36 is in a ratio of high value to the coefficient of elasticity of Z direction and first coefficient of elasticity to directions X.Therefore, be Z direction when moving at vibrating body 20 and supporting mass 30 to second direction, in the first strain portion 36, be difficult to produce elastic deformation, when the Z direction is vibrated, the first strain portion 36 is difficult to produce the vibration interference on the direction of not expecting.
As shown in Figure 4, in elastic bearing component 33, be formed with the notch 37,37 that the support foot 31 of supporting mass 30 is cut to directions X at the both ends of middle board 34.In Fig. 4, the penetraction depth size of notch 37,37 is represented by D.The leaf spring material of the part that promptly in Fig. 4, is clipped by width dimensions W and penetraction depth dimension D as the scope leaf spring material, that clipped by notch 37,37 that constitutes support foot 31 becomes distortion board 38.Distortion board 38 is not fixed through the lower surface 22c with respect to the yoke 22 that constitutes vibrating body 20 such as bonding agent.Constitute the second strain portion 39 by distortion board 38 with from the said centre board 34 of these distortion board 38 bendings.
When vibrating body 20 and supporting mass 30 when second direction is the action of Z direction, the second strain portion, 39 strains.The main variant part of the second strain portion 39 is distortion board 38, and with respect to moving of the Z direction of vibrating body 20 and supporting mass 30, distortion board 38 produces crooked deformation to the Z direction.At this moment, also produce crooked deformation in middle board 34 and the crooked interface of being out of shape board 38.
When the penetraction depth D of notch 37,37 changed, the length dimension of the directions X of distortion board 38 changed, and second coefficient of elasticity changes.Thus, change through making penetraction depth D, what can adjust vibrating body 20 and supporting mass 30 is the eigentone of Z direction to second direction.But because the variation of the penetraction depth D of switch-in part 37,37 does not bring any variation to first variant part 36, therefore when adjustment second coefficient of elasticity, first coefficient of elasticity of the first strain portion 36 can not change.
As shown in Figure 1, framework 10 is provided with opposed paired magnet supporting board 13,13 on the Y direction.On the inner surface of a side magnet supporting board 13, be fixed with and member 42a take place in the coil 41 common magnetic fields that constitute magnetic drive divisions 40, on the inner surface of the opposing party's fixedly board 12, be fixed with same and the coil 41 common magnetic fields generation member 42b that constitute magnetic drive divisions 40.
Shown in Fig. 5 (A), member 42a takes place and has first magnet 43a that is positioned at upside and the second magnet 44a that is positioned at base plate 11 sides in a side magnetic field.The first magnet 43a and the second magnet 44a are the length dimension elongated shape bigger than the width dimensions of Z direction of directions X.In Fig. 5 (A), the center O 1 of the first magnet 43a is positioned at the left side, and in Fig. 5 (A), the center O 2 of the second magnet 44a is positioned at the right side.The first magnet 43a become the N utmost point with the opposed magnetic pole strength of outstanding end 21b magnetic core 21 by excitation, the second magnet 44a is become the S utmost point with the opposed magnetic pole strength of outstanding end 21b by excitation.
When vibrating body 20 under the state that is not having the external force effect is supported to neutral attitude through elastic bearing component 33,33; The center O 0 of the outstanding end 21b of magnetic core 21 is positioned at intermediate point with respect to said center O 1 with center O 2 on directions X, and on the Z direction, is positioned at intermediate point.
Member 42b takes place and clips X-Z face and said magnetic field and member 42a takes place in the face of the title structure in the magnetic field that the opposed the opposing party of member 42a takes place with magnetic field shown in Figure 5.Magnetic field take place member 42b have with the said first magnet 43a in the face of the first magnet 43b that claims, with the second magnet 44b of the said second magnet 44a in the face of claiming.Need to prove the not shown second magnet 44b in Fig. 1.The first magnet 43b and the opposed magnetic pole strength of outstanding end 21b magnetic core 21 that member 42 takes place in magnetic field is become the S utmost point by excitation.The second magnet 44b is become the N utmost point with the opposed magnetic pole strength of outstanding end 21b by excitation.That is, the opposed first magnet 43a is become reciprocal polarity with the magnetic pole strength of the first magnet 43b by excitation, and the opposed second magnet 44a is become reciprocal polarity with the magnetic pole strength of the second magnet 44b by excitation.
