In a further embodiment, the lower casing 12 integrally can also be made up of permeability magnetic material, and so, lower casing 12 itself just may be used
Used as magnetic-conductance portion 121.
Coil 2 has the first edge 21 and the second edge 22, and two edge 21,22 can be each perpendicular to direction of vibration, with
Increase the effective length of coil 2 and the phase separation of Halbach array 4, be perpendicular to paper in the embodiment shown in fig. 1
Direction.
The edge 22 of first edge 21 and second can be straight flange, or arc-shaped edges, for arc-shaped edges, should be perpendicular to
Direction of vibration is construed as the arc-shaped edges with the tangent line perpendicular to direction of vibration.
The Halbach array 4 is included in two side magnet 41a, the 41b arranged on direction of vibration, two pieces of side magnet 41a,
The magnetizing direction of 41b conversely, and the plane where being each perpendicular to coil 2, in the embodiment shown in fig. 1, namely under
Shell 12.
In the embodiment shown in Fig. 1 and Fig. 2, the magnetizing direction of side magnet 41a for from bottom to up, i.e. side magnet 41a's
Lower end is S poles, upper end is N poles；And the magnetizing direction of side magnet 41b is for from top to bottom, i.e., the lower end of side magnet 41b be N poles, on
It is S poles to hold.
In a further embodiment, or side magnet 41a magnetizing direction for from top to bottom, and side magnet 41b
Magnetizing direction is for from bottom to up.
Side magnet 41a the first edge 21 of correspondence, side magnet 41b the second edge 22 of correspondence, so, with magnetizing shown in Fig. 2
As a example by direction, can enable that the magnetic line of force that side magnet 41b sends is passed through with the direction with vertical component at least in part
Second edge 22, and enable to return to the magnetic line of force of side magnet 41a and passed through with the direction with vertical component at least in part
First edge 21, and then produce along the driving force of direction of vibration.
Further, the first edge 21 can also be made to be alignd with side magnet 41a, and causes the second edge 22 and side magnet
41b aligns, wherein, alignment is set to be the first edge 21 and side magnet 41a is located on direction of vibration flat where coil 2
In the coverage of the projection on face, the second edge 22 is located at side magnet 41b in the plane where coil 2 on direction of vibration
Projection coverage in.So, equally by taking the magnetizing direction shown in Fig. 2 as an example, the magnetic that side magnet 41b can be caused to send
The line of force most of can pass through the second edge 22 with generally vertical direction, and enable to return to the magnetic line of force of side magnet 41a
It is most of that first edge 21 is passed through with generally vertical direction, and then realize effective utilization of drive device.
According to Fig. 2, the sense of current in coil 2 is so that the electric current of the first edge 21 from outer sensing and makes
When obtaining the electric current of the second edge 22 from outside interior sensing, electromagnet will apply magnetic force (repulsion) F21 to side magnet 41a, and to side magnetic
Iron 41b applies magnetic force F22 (gravitation), and the two direction is identical, and according to left hand rule, coil 2 is applied to Halbach array 4
The direction of the reaction force F1 of Ampere force is consistent with the direction of magnetic force F21, F22.
When the electric current in coil 2 is with respect to shown in Fig. 2 reversely, magnetic force F21, F22, and the reaction force of Ampere force F1 are also equal
Will be reverse, that is, right side is directed to, and then the driving force vibrated repeatedly is provided to oscillator part.
