【Specific embodiment】
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1-Figure 3, a kind of linear electric machine 100 is included shell, the vibration component located inside the shell, is connected with shell
Magnetic steel component and for vibration component being flexibly supported the Flexible Connector 103 in inside the shell.Shell includes side and opens
Housing 101 and be connected with housing 101 and form the cover plate 102 of receiving space.Housing 101 have longer side limit and with longer
The shorter lateral sides that side is connected.
Vibration component includes coil 104 and the mass 105 being connected with coil 104.Coil 104 has major axis and short
Axle, mass 105 has two, sets respectively and is connected with the short axle of coil 104.
Magnetic steel component includes the two main magnet steel 106 being oppositely arranged and is located in the soft magnetism material between two main magnet steel 106
Material 108, two main magnet steel 106 polarity identical magnetic poles are oppositely arranged.Coil 104 is arranged around main magnet steel 106.Magnetic steel component also enters
One step includes the side magnet steel 107 around coil 104.Side magnet steel 107 is along the longer side limit setting of housing 101, side magnet steel 107
Form magnetic gap and main magnet steel 106 between.Of reciprocating vibration along Z-direction under the action of a magnetic force after coil 104 energising.Side magnet steel
On can also be not provided with soft magnetic materials.
Because coil 104 is arranged around main magnet steel 106, therefore main magnet steel 106 and side magnet steel 107 all can do in Z-direction
Obtain thicker, the thickness of shell can be made full use of, therefore increase magnetic field intensity, improve Magnetic driving power.
