Abstract
The invention relates to a vibrator which comprises permanent magnets, a coil and a hollow cylinder body, wherein, the permanent magnets are one pair, the two permanent magnets are respectively fixedon two sides of a magnetic conductive sheet, the ends with the same polarity of the two permanent magnets are opposite, the two permanent magnets and the magnetic conductive sheet are positioned in acavity of the cylinder body, a magnetic conductive ring is sheathed at the middle part of the surface of the cylinder body, the coil is divided into two parts and wound on the surface of the cylinderbody which is positioned on two sides of the magnetic conductive ring, a housing is sheathed outside the cylinder body, and two ends of the coil are introduced out of the housing. The vibrator has theadvantages of reasonable structure, sensitive vibration, good vibration effect and long service life, and can be widely applied on products like massage devices, sex toys, mobile phones and the like.
Description
Technical field
The present invention relates to a kind of electromagnetic shaker, specifically a kind of electromagnetic vibrator.
Background technology
The basic structure of existing a kind of electromagnetic vibrator is, is provided with the vibrations part that has magnet in the cavity of a hollow component, against spring is arranged, is wound with coil in the outside of hollow component between the one or both ends of vibrations part and the hollow component.When this kind electromagnetic vibrator passed through alternating current at coil, the vibrations part that has magnet can produce vibrations.The shortcoming that above-mentioned existing electromagnetic vibrator exists is: the location of vibrations part be by with spring against realizing that the amplitude the during vibration of vibrations part can be subjected to the influence of spring, vibrating effect is not ideal enough; Especially at the electric current by coil hour, the resistance of spring can be more obvious to the obstruction of vibrations part.
Summary of the invention
The object of the present invention is to provide a kind of sensitivity, little electromagnetic shaker of vibrations part when vibrations damping of shaking.
For achieving the above object, the present invention adopts following scheme: a kind of electromagnetic shaker, include permanent magnet, coil and hollow cylinder, permanent magnet is a pair of, two permanent magnets are separately fixed at the both sides of a magnetic conduction sheet, and the end that two permanent magnet polarity are identical is relative, two permanent magnets and magnetic conduction sheet are in the cavity of cylinder, be with a magnetic guiding loop at the middle part of damaged surface, the coil separated into two parts is wrapped on the surface of cylinder of magnetic guiding loop both sides, the outside of cylinder is with housing, outside the two ends pass-out housing of coil.
By such scheme as seen, when coil passes through alternating current, the polarity of the continuous conversion in coil two ends can make vibrations part constantly reciprocating motion in cylinder that two permanent magnets and magnetic conduction sheet constitute, realize vibrating effect, because two outsides of vibrations part are without any obstruction, the little and vibrations of vibrations part when vibrations damping freely; When the coil no power, because two permanent magnets are all attractive to magnetic guiding loop, like this, the vibrations part then can rest on the middle part in the cylinder all the time.
The present invention is rational in infrastructure, and vibrations are sensitive, vibrating effect is good, and long service life, and it can be applied on the products such as massager, sex toy, mobile phone widely.

Referring to Fig. 1, Fig. 3
The bottom of housing 1 is fixed with a connecting plate 7 that is similar to " L " shape, the cooperation of pegging graft each other of the connecting plate 7 on the two housings 1.By the pegging graft each other and the position that housing 1 and magnetic guiding loop 3 contact with each other is carried out bonding of two connecting plates 7, two housings 1 is enclosed within on the cylinder 2 reliably.
Referring to Fig. 1, Fig. 2
Have the radiating groove 1b more than two in the side of housing 1, have the through hole 1a that communicates with cylinder 2 cavitys in the end of housing 1.Radiating groove 1b can make the good heat radiation of coil 6, and the effect of through hole 1a is, back and forth during vibrations, the gas of cylinder 2 cavitys can be discharged from through hole 1a at two permanent magnets 5 and magnetic conduction sheet 4.
Referring to Fig. 4
Being in tie point between two parts of coil 6 of magnetic guiding loop both sides and two the end of a thread of whole winding 6 is arranged on the upper junction plate 7, its concrete mode is: be provided with four contacts on connecting plate 7, wherein contact A links to each other with contact B, contact A and contact B are the tie point between two parts of the coil 6 that is in the magnetic guiding loop both sides, two parts of coil 6 are realized interconnecting by joining with contact A, contact B respectively, and two the end of a thread of whole winding 6 are connected with contact C, contact D respectively.Be connected to lead 8, the lead 9 of drawing outside housing at contact C, contact D, promptly two the end of a thread of coil 6 are connected to pass-out housing outer lead 8, lead 9 respectively, then can realize outside two the end of a thread pass-out housings of coil 6.
