Description
Technical field
The present invention relates to electromagnet.
Background technology
Existing high-frequency vibration electromagnet is to form different magnetic field forces by sense of current in change coil, by magnetic
Field force acts on and active force is transferred to shell surface and forms vibration by electrician's iron of linear movement.The defect of such vibration electromagnet is
The effect of electrician's iron only single receiving coil magnetic field force, stroke, amplitude are all less than normal, and generated effect of vibration power is weaker, and
It is that noise phenomena is apparent when shell carries out the transmission of active force.
Invention content
The technical problem to be solved in the present invention is, provides a kind of improved high-frequency vibration electromagnet.
The technical solution adopted by the present invention to solve the technical problems is：High-frequency vibration electromagnet, including skeleton, outside skeleton
It places and is arranged with coil, endoporus is axially formed in the skeleton, the first permanent magnet, second are installed in the endoporus of the skeleton
Permanent magnet and third permanent magnet, first permanent magnet, third permanent magnet are fixed on the both ends of endoporus, second permanent magnet
It is movably installed in endoporus, and corresponding with the coil position；Wherein, one end of second permanent magnet and the first permanent magnet
Inner end, the second permanent magnet the other end and the inner end of third permanent magnet be that like pole is opposite.
The foregoing high-frequency vibration electromagnet, the coil are set to one end of skeleton partially.
The high-frequency vibration electromagnet, endoporus both ends wall surface are equipped with embedded groove, the first permanent magnet,
Third permanent magnet is individually fixed in corresponding embedded groove.
The foregoing high-frequency vibration electromagnet, the coil are externally provided with shell.
Implement technical scheme of the present invention, at least there is advantageous effect below：By the cooperation of each permanent magnet, effectively add
The strong oscillation intensity of electromagnet.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing：
Fig. 1 is utility model diagram；
Fig. 2 is one schematic diagram of the utility model use state；
Fig. 3 is two schematic diagram of the utility model use state；
Fig. 4 is three schematic diagram of the utility model use state；
Mark is described as follows in figure：

Specific implementation mode
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
The specific implementation mode of the present invention.
High-frequency vibration electromagnet as shown in Figure 1, including skeleton 1, skeleton 1 are placed be arranged with coil 2 outside, the skeleton 1
Middle axial direction is formed with endoporus 3, and the first permanent magnet 4, the second permanent magnet 5 and third permanent magnetism are equipped in the endoporus 3 of the skeleton 1
Body 6 is generally permanent magnet, and first permanent magnet 4, third permanent magnet 6 are fixed on the both ends of endoporus 3, second permanent magnetism
Body 5 is movably installed in endoporus 3, and corresponding with 2 position of the coil；Wherein, one end of second permanent magnet 5 with first forever
The inner end of magnet 4, the second permanent magnet 5 the other end and the inner end of third permanent magnet 6 be that like pole is opposite.
As in Figure 2-4, coil 2 generates different magnetic directions by changing electric current inflow direction, the first permanent magnet 4,
The pole orientation of second permanent magnet 5 and third permanent magnet 6 is fixed, immutable.Fig. 2：When 2 no power of coil, the second 5 liang of permanent magnet
Hold polarity identical with the polarity of the first permanent magnet 4,6 corresponding end of third permanent magnet respectively, identical charges repel each other ensures the second permanent magnet 5
It is not contacted with any one end, is maintained at intermediate state.Fig. 3：Magnetic field N is generated when coil 2 is powered ' ' ' S ' ' ' when, according to anisotropic phase
Principle is inhaled, the second permanent magnet 5 moves right at this time；The first permanent magnet 4 pushes to the right the second permanent magnet 5, third permanent magnet 6 simultaneously
Thrust compressed, but third permanent magnet 6 and the second permanent magnet 5, according to principle of same-sex repulsion, the two does not contact.Fig. 4：Change line
2 current directions are enclosed to be powered behind generation opposing magnetic field, identical charges repel each other by the SN of S ' ' ' N ' ' ' and the second permanent magnet 5 that coil 2 generates, the
Two permanent magnets 5 move downward；6 compressed energy of third permanent magnet release simultaneously pushes the second permanent magnet 5 to move downward, the
The thrust of one permanent magnet 4 is compressed.
So by the current direction of varying cyclically coil 2, the second permanent magnet 5 generates axial reciprocating motion, both ends
The reciprocating motion energy impact that first permanent magnet 4 and third permanent magnet 6 are generated by the second permanent magnet 5, impact are transmitted to skeleton 1
On, production vibration.Second permanent magnet 5 itself has magnetic field, and the magnetic field formed that is powered with coil 2 forms cooperation to realize axial direction
Movement, then assisted by the first permanent magnet 4, third permanent magnet 6, it is stronger to the effect of vibration of skeleton 1.
In some embodiments, 2 eccentric setting of coil is that the stroke dynamics of the second permanent magnet 5 is uneven in one end of skeleton 1
Weighing apparatus, forms difference, and vibrating effect is more obvious.2 periphery of coil can be arranged shell 7 according to specific installation requirements and form protection,
And embedded groove can be set in 3 both ends wall surface of endoporus, the first permanent magnet 4, third permanent magnet 6 are individually fixed in corresponding embedded groove
In.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the present invention can have various changes, combination and variation.All within the spirits and principles of the present invention, made by
Any modification, equivalent substitution, improvement and etc. should be included within scope of the presently claimed invention.
