First embodiment
It please refers to Fig.1 to Fig.3, present embodiments provides a kind of linear vibration motor 100, the linear vibration motor 100
Including stator component, oscillator component and silencing spring 80.
Stator component includes bottom plate 10 and the printed circuit board being mounted on bottom plate 10 20, coil 30 and shell 40.Line
Circle 30 is connected to by printed circuit board 20 with extraneous power supply.Oscillator component and silencing spring 80 are located at bottom plate 10 and surround with shell 40
Cavity in.
Oscillator component includes magnetic yoke 50 and the magnet being mounted on inside magnetic yoke 50 60 and is mounted on matching outside magnetic yoke 50
Pouring weight 70.Magnetic yoke 50 is closed at one end, the tubbiness of open at one end.Clump weight 70 is ring-type, and is set in the outer peripheral surface of magnetic yoke 50.
Gap between the corresponding magnetic yoke 50 of coil 30 and magnet 60, during oscillator component vibrates up and down in shell 40, magnet 60
Extend into or out gap.
Silencing spring 80 is hollow cyclic structure, and silencing spring 80 is located at the periphery of coil 30 and is spaced with coil 30
Setting.One end of silencing spring 80 is connected to shell 40 close to one end of bottom plate 10, and the other end of silencing spring 80, which is welded on, matches
On pouring weight 70, thus in 40 internal vibration of shell under the action of enabling oscillator component silencing spring 80.
The working principle of linear vibration motor 100 provided in this embodiment: referring to Fig. 3, coil 30 passes through printed circuit
After plate 20 is connected to extraneous power supply, 30 periphery of coil forms electric field, and printed circuit board 20 will control the variation of electric field, magnet 60
By the effect of electric field force in the electric field of variation, meanwhile, also by under the elastic force effect of silencing spring 80, magnet 60 connects magnet 60
Upper and lower linear oscillator is realized the function of linear vibration motor 100 by logical magnetic yoke 50 and clump weight 70.
Fig. 4 to Fig. 5 is please referred to, shell 40 is closed at one end, the tubbiness of open at one end.Oscillator component and silencing spring 80
It is arranged inside shell 40, silencing spring 80 fills up the cavity of shell 40 as far as possible and oscillator component is supported on inside shell 40,
Silencing spring 80 is relatively uniform to the support force of oscillator component.
Fluted 41 are opened up on the side wall of shell 40 and close to the position of open end, one end of silencing spring 80 is welded in
In groove 41, in such manner, it is possible to improve the bonding strength between silencing spring 80 and shell 40.
Referring to Fig. 6, noise reduction elastic slice 81 includes bending section 811 and the first company for being connected to 811 both ends of bending section
Socket part 812 and second connecting portion 813, first connecting portion 812 (end for being located at right side in Fig. 6) is for being welded on stator component
On, second connecting portion 813 (end for being located at left side in Fig. 6) is for being welded on oscillator component.
Preferably, the junction of second connecting portion 813 and bending section 811 forms notch 814, and notch 814 is for reducing the

Card noise reduction elastic slice 81 is spaced apart from each other, and is not interfere with each other.
It is become larger on bending section 811 from middle part to both ends width, the width of first connecting portion 812 and second connecting portion 813
Degree is greater than the width of bending section 811, makes the entirety of noise reduction elastic slice 81 in the structure type of big at both ends and small in middle, to improve noise reduction bullet
The vibrating fatigue service life of piece 81.
In this way, the part on bending section 811 since middle part closer to first connecting portion 812 and second connecting portion 813 is got over
Width can offset the influence of first connecting portion 812 and the welding of second connecting portion 813 to the intensity of noise reduction elastic slice 81.
Preferably, for connect oscillator part second connecting portion 813 size be greater than for connecting shell 40 first
Interconnecting piece 812, in this way, guarantee that oscillator component can be stablized, balancedly be supported, meanwhile, avoid noise reduction elastic slice 81 and shell
Welding range between 40 is excessive, influences the intensity and elastic force of noise reduction elastic slice 81.Further, since welding will reduce the strong of material
Degree, the minimum part of 81 intensity of noise reduction elastic slice are also first connecting portion 812 and the part that groove 41 welds, therefore, the first connection
The length (length that first connecting portion 812 is welded in groove 41) that portion 812 extends in groove 41 can be set according to strength demand
2 to 3 times of 812 width of first connecting portion are calculated as, to guarantee to have enough weld strengths, meanwhile, guarantee that noise reduction elastic slice 81 has
There is enough intensity.
It is easily understood that first connecting portion 812 and 813 local inclination portion of second connecting portion, 811 sizes are larger, but the
The region that one interconnecting piece 812 and second connecting portion 813 are actually used in welding is not entire first connecting portion 812 and the second connection
Portion 813, only solder joint can be fallen in first connecting portion 812 and second connecting portion 813, and the area of actual welding connects much smaller than first
The area of socket part 812 and second connecting portion 813.
Preferably, on bending section 811 both ends the ratio between width and the width at middle part are as follows: be greater than 1 and be less than or equal to 3.The
The ratio between the width of the widest part on one interconnecting piece 812 or the width of second connecting portion 813 and bending section 811 are as follows: greater than 1 and be less than or
Equal to 3.
Fig. 7 to Fig. 8 is please referred to, silencing spring 80 includes inner ring 82 and at least three noise reduction elastic slices 81, it is preferable that this implementation

Second connecting portion 813 successively contact integrally.In this way, inner ring 82 and second connecting portion 813 are welded on oscillator component together,
The stability that silencing spring 80 supports oscillator component can be further increased, oscillator component is avoided to occur in vibration processes partially
It moves, shock other component makes a noise.
Preferably, three noise reduction elastic slices 81 are spaced uniformly, and identical position is corresponded on three noise reduction elastic slices 81 positioned at same
On circumference.
It is easily understood that the quantity of noise reduction elastic slice 81 may be 3 to 6, it can for larger-size vibrating motor
5 or 6 noise reduction elastic slices 81 are designed, vibrating motor lesser for size can design 3 or 4 noise reduction elastic slices 81.
The first connecting portion 812 of three noise reduction elastic slices 81 for being connected to shell 40, three noise reduction bullets evenly and at intervals
The second connecting portion 813 of piece 81 is connected to evenly and at intervals on clump weight 70, and the bending section 811 of three noise reduction elastic slices 81 is mutual
Every setting.In this way, three noise reduction elastic slices 81 are spaced apart from each other completely, every 81 independence and freedom of noise reduction elastic slice has been played to the maximum extent
The ability of oscillation avoids three noise reduction elastic slices 81 from interfering with each other, and avoids issuing vibrating noise.In particular, three first connecting portions
812 is mutually indepedent, and the position for making silencing spring 80 actually play elastic vibration is increased, and elastic property is improved.
The maximum curvature at middle part on the bending section 811 of every noise reduction elastic slice 81, the middle part correspondence on each bending section 811 are set
Set a second connecting portion 813.In this way, the compact-sized of silencing spring 80 can not only be made, and make on each bending section 811
The Curvature varying of various pieces is more gentle, thus, the stress for generating silencing spring 80 in vibration processes is smaller.
