Particularly, in Figure 5 shown in
with
represent the sense of current in a certain moment first voice coil loudspeaker voice coil 6 and the second voice coil loudspeaker voice coil 7.Be denoted as in figure
the sense of current be vertical view towards inner, be denoted as
the sense of current is that vertical view is towards outward.The current trend of each voice coil loudspeaker voice coil of simple signal in figure, according to left hand rule, because the direction of left the ring magnetic field force be subject to and the magnetic field force that right ring is subject to is all identical with size, therefore, the direction of the magnetic field force F that whole voice coil loudspeaker voice coil is subject to is for the right.But because voice coil loudspeaker voice coil itself is positioned on pedestal, therefore voice coil loudspeaker voice coil can not move, but due to the relation of active force and reaction force, permanent magnet is subject to active force that is contrary with F direction and the F ' that size is identical, and permanent magnet and balancing weight 2 are together suspended in spatial accommodation, and the strain direction of elastic supporting member for supporting optical member is vertical and lower case side wall, namely lower casing diapire is parallel to, therefore, permanent magnet and balancing weight 2 are together under the action of a magnetic force to left movement the direction of arrow of F and F ' (in the figure).
When the current direction changes (as shown in Figure 6), be denoted as in figure
the sense of current is similarly vertical view towards inner, is denoted as
the sense of current is similarly vertical view towards outward.According to left hand rule, because the direction of left the ring magnetic field force be subject to and the magnetic field force that right ring is subject to is all identical with size, therefore, the direction of the magnetic field force F that whole voice coil loudspeaker voice coil is subject to is for left.But because voice coil loudspeaker voice coil itself is positioned on pedestal, therefore voice coil loudspeaker voice coil can not move, but due to the relation of active force and reaction force, permanent magnet is subject to active force that is contrary with F direction and the F ' that size is identical, and permanent magnet and balancing weight 2 are together suspended in spatial accommodation, and the strain direction of elastic supporting member for supporting optical member is vertical and lower case side wall, namely lower casing diapire is parallel to, therefore, permanent magnet and balancing weight 2 together move right the direction of arrow of F and F ' (in the figure) under the action of a magnetic force.Motion shown in Fig. 5 and Fig. 6 hockets, and makes permanent magnet and balancing weight 2 form the reciprocating motion of left and right, is namely parallel to the vibration of lower casing diapire.
Due to permanent magnet and between the first voice coil loudspeaker voice coil 6 and the second voice coil loudspeaker voice coil 7, there is magnetic gap, and the magnet on both sides (i.e. the first permanent magnet 9 and the 3rd permanent magnet 11) is tilted-putted, compared with vertical mode of placing, the magnet slant setting on both sides can be increased the area through voice coil loudspeaker voice coil, magnetic flux density through voice coil loudspeaker voice coil is increased, thus make permanent magnet and balancing weight 2 when bilateral reciprocation, magnetic flux through voice coil loudspeaker voice coil also increases greatly, and then promotes the vibrating effect of electronic product.
Describe in an illustrative manner according to oblique magnetizing motor of the present utility model above with reference to accompanying drawing.But, it will be appreciated by those skilled in the art that the oblique magnetizing motor that above-mentioned the utility model is proposed, various improvement can also be made on the basis not departing from the utility model content.Therefore, protection range of the present utility model should be determined by the content of appending claims.
