Below by for the operation principle of Fig. 4 simple declaration the utility model linear vibration motor.According to the left hand rule judging electrical conductor Impact direction in magnetic field, stretch out left hand, make thumb and all the other four finger vertical, and all with palm in same plane; Allow magnetic induction line enter from the centre of the palm, and make four fingers point to sense of current, at this moment the direction of thumb indication is exactly the direction of electrified wire suffered Ampere force in magnetic field.Suppose the sense of current in coil, be denoted as in figure "
" sense of current be vertical view towards inner, be denoted as "
" sense of current be vertical view towards outward, suppose first coil be "
with
", second coil must also be "
with
", such coil just can all stressed F to the right, because coil maintains static, based on the relation of active force and reaction force, then and the stressed F ' left of permanent magnet.So, the permanent magnet being subject to motive force left just drives balancing weight to do translational motion left together, thus the spring on the left of extruding balancing weight, the spring on the right side of stretching balancing weight.In like manner, when the current direction changes, according to left hand rule, the direction of the magnetic field force F that coil is subject to is for left.But because coil maintains static, then permanent magnet is subject to active force that is contrary with F direction and the F ' that size is identical, the permanent magnet being subject to motive force to the right just drives balancing weight to do translational motion to the right together, makes the spring at balancing weight two ends continue to be stretched/to extrude after the reinstatement of extruding/extended state simultaneously.Above-mentioned motion hockets, and the oscillator that the vibrating mass of permanent magnet and conductive magnetic yoke composition and balancing weight are formed moves reciprocatingly in the direction of the mounting plane being parallel to stator.
In the above-described embodiments, vibrating mass comprises four block permanent magnets, but is also not limited to said structure in concrete application process, also suitably can select the quantity of the permanent magnet forming vibrating mass according to the size of vibration force needed for application product.In the embodiment shown in Fig. 1 and Fig. 2, vibrating mass is embedded in balancing weight, to drive balancing weight horizontal vibration.Particularly, be provided with the avoiding structure of dodging stator at the middle part of balancing weight, the center that balancing weight is provided with avoiding structure is provided with the groove holding vibrating mass.In concrete assembling process, first the permanent magnet of composition vibrating mass and conductive magnetic yoke can be fixed together, then in modes such as gluing or laser electric welding, vibrating mass entirety be fixed in a groove.
In addition, linear vibration motor of the present utility model also comprises two vibration axis of guide 51a, 51b, limit spring 52a, 52b and guide vane end stop 53a, 53b being arranged on balancing weight 31 two ends, and limit spring is set on the vibration axis of guide 51a, 51b.In the embodiment shown in Fig. 1, Fig. 2, guide vane end stop 53a, 53b are separately fixed on upper casing 1, two the vibration axis of guides 51a, 51b are separately fixed at the two ends of balancing weight 31, guide vane end stop 53a, 53b are also provided with for the reciprocating pilot hole of the vibration axis of guide.Like this, under the effect in the magnetic field that vibrating mass produces after stator energising, drive balancing weight 31 and be fixed on the vibration axis of guide 51a, 51b limited range internal vibration at pilot hole at balancing weight 31 two ends.
Wherein, be set in the vibration axis of guide 51a, 51b upper limit spring 52a, 52b respectively and be limited between guide vane end stop 53a, 53b of balancing weight 31 and correspondence respectively, for the vibration of oscillator provides elastic restoring force.
In addition, in order to reduce the frictional force between the vibration axis of guide and pilot hole, improve the quality of products as far as possible, can also on one end that the vibration axis of guide gos deep into pilot hole sheathed axle sleeve 54a, 54b, the contact-making surface smooth abrasion-proof of axle sleeve and pilot hole.The increase of axle sleeve reduces the contact area of the vibration axis of guide and pilot hole, and the material that density is high, smooth surface is wear-resisting can be adopted to make axle sleeve, on the basis not increasing cost, the frictional force between the vibration axis of guide and pilot hole can be reduced as far as possible, improve degree of lubrication.
