It is enhanced, according to Ampere's law (screw law), the poly- magnetic portion 83 of two iron core stators 8 will have polarity and can attract
Or repel corresponding magnet, so as to drive the iron core 2 to rotate.
When magnet is distributed by Fig. 5 modes, after coil 7 is powered, such as within the scope of positive wave, two iron core stators 8
For the magnetism in two poly- magnetic portions 83 on the contrary, one end forms the poles N, one end forms the poles S.At this time since identical charges repel each other that there is a natural attraction between the sexes for magnet,
As shown in fig. 7, the poly- magnetic portion 83 of the poles S will attract the poles N magnet, and push away the poles S magnet；The poly- magnetic portion 83 of the poles N will attract the poles S magnetic
Iron, and the poles N magnet is pushed away, so that iron core 2 rotates, clockwise as shown in Figure 7 rotation.And in negative wave range
When interior, as shown in figure 8, its operation principle is similar, since current direction is reversed, thus the magnetic of poly- magnetic portion 83 will invert, to
Current magnet can be repelled, and attract the magnet of neighbouring opposite polarity, so that iron core 2 rotates backward, such as Fig. 8
Shown in rotate counterclockwise.When being persistently passed through positive and negative square wave to coil 7, iron core 2 will in limited angle reciprocating rotary
It is dynamic, to drive 1 reciprocating rotation of central rotating shaft.
When magnet is distributed by Fig. 6 modes, after coil 7 is powered, such as within the scope of positive wave, two iron core stators 8
The polarity in two poly- magnetic portions is identical, is such as all the poles N, is in the poles N as shown in Figure 10 at this time since identical charges repel each other that there is a natural attraction between the sexes for magnet
Poly- magnetic portion 83 will attract the poles S magnet, and push away the poles N magnet it is as shown in Figure 10 so that iron core 2 rotates
Clockwise rotates.And when within the scope of negative wave, as shown in figure 11, operation principle is similar, since current direction is reversed, thus it is poly-
The magnetic of magnetic portion 83 will invert, and be changing into the poles S by the poles N, so as to repel the current poles S magnet, attract the neighbouring poles N magnetic
Iron, so that iron core 2 rotates backward, as shown in figure 11 rotates counterclockwise.When being persistently passed through positive and negative square wave to coil 7
When, iron core 2 will in limited angle reciprocating rotation, to drive central rotating shaft 1 move back and forth.
Since 2 rotational angle of iron core is small, high-frequency vibration can be generated, and can guarantee that the vibration of generation is stablized.
The present invention connects iron core 2 and fixed seat 4 by profile leaf spring 91, and profile leaf spring 91 and iron core 2 and fixed seat 4 connect
Contacting surface is big, and its dog-ear 911 is effective against itself torsion, thus solves the problems, such as that conventional elastic piece and spring are yielding.This
Outside, outer housing 5 of the invention is coated on outside iron core stator 8, not only can effectively protect internal structure, but also its end is open,
Can quick pairing connection fixing base 4, when assembly, after one end of profile leaf spring 91 is fixed, profile leaf spring 91 can be inserted into solid
In reservation 4, assembly then can be rapidly completed, which reduce assembly difficulty, substantially increase assembly effect.The present invention's is small-sized
High-frequency vibration device has assembly simple, be unlikely to deform, low noise the features such as, it has strong practicality, preferably widelys popularize.
