As shown in the Fig. 4-2, being denoted as " ⊙ " sense of current is that vertical view faces out, and is denoted asThe sense of current is that vertical view is towards inner, it is assumed that the energising direction of the first stator coil be "And ⊙ ", the energising of second stator coil and the first stator coil is in opposite direction is " ⊙ and", according to left hand rule the first stator coil and the second stator coil, the Impact direction in magnetic field is F ' to the left, owing to stator coil maintains static, and relation based on active force Yu counteracting force, then permanent magnet stress F to the right.So, just driven balancing weight to do translational motion to the right together by the permanent magnet of motive force to the right, thus extrude the bolster (such as, spring or shell fragment) on the right side of balancing weight, the bolster on the left of stretching balancing weight.
In like manner, when the sense of current in the first stator coil and the second stator coil changes simultaneously, according to left hand rule, the direction of the magnetic field force F ' that stator coil is subject to is to the right.But owing to stator coil maintains static, then permanent magnet is by the active force of in opposite direction with F ' and that size is identical F, just driven balancing weight to do translational motion to the left together by the permanent magnet of motive force to the left, make the bolster at balancing weight two ends continue to be stretched/extrude after extruding/extended state restores to the original state simultaneously.Alternately, the oscillator making vibrating mass and the balancing weight of permanent magnet and conductive magnetic yoke/Magnet composition be formed moves reciprocatingly in the direction of the mounting plane being parallel to stator, thus realizes the vibration of linear vibration motor in above-mentioned motion.
It should be noted that the situation that the permanent magnet that stator is provided only in the situation of oscillator side and vibrating mass is set to two pieces is all similar with the vibration principle of above-mentioned linear vibration motor, here is omitted.
Shown in Fig. 1, in another detailed description of the invention of the present utility model, it is symmetrically arranged with at the two ends of balancing weight 5 and recommends Magnet 4 and house and recommend the accepting groove of Magnet 4 and (include accepting groove 51a and accepting groove 51b, lower same), recommend Magnet 4 for two pieces and be individually positioned in corresponding accepting groove.Position corresponding with recommending Magnet 4 on shell is fixedly installed and recommends coil 2 around recommend Magnet 4, after recommending coil 2 energising, the Magnet 4 of recommending recommending coil 2 internal with it matches, it is fixed on shell immovable owing to recommending coil 2, so that recommending Magnet 4 by active force onesize, in opposite direction, move reciprocatingly offer driving force along on the direction of the plane parallel at stator place for oscillator.
Wherein, for convenience of to recommending the coiling of coil 2 and fixing, linear vibration motor of the present utility model can also include recommend coil rack 3, recommend coil 2 to be wound on and recommend on coil rack 3, by being fixed on recommending coil rack 3 on the shell of linear vibration motor, it is possible to realize indirectly making to recommend coil 2 and be fixed on shell.
It addition, can also arrange shell fragment 10 at the two ends of balancing weight 5, one end of shell fragment 10 is connected with balancing weight, and the other end is fixed on shell, thus is hung on by oscillator in the space that shell is formed, and the vibration for oscillator provides elastic restoring force;The magnetic field of change is produced after magnetic conduction core energising in stator, moved reciprocatingly along the direction parallel with stator place plane by the always drive vibrator of walking changing magnetic field magnetic line, i.e. permanent magnet in vibrating mass and the magnetic conduction core in stator produces the traction thrust interacted, and finally makes linear vibration motor vibrate
