Description

Electromagnetic shaker

Technical field

The utility model 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.

The utility model content

The purpose of this utility model is to provide a kind of sensitivity, little electromagnetic shaker of vibrations part when vibrations damping of shaking.

For achieving the above object, the utility model 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 utility model 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.

Embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1

The electromagnetic shaker that the utility model provides, include permanent magnet 5, coil 6 and hollow cylinder 2, permanent magnet 5 is a pair of, two permanent magnets 5 are separately fixed on the both sides of a magnetic guiding loop 4 by bonding mode, and the end that two permanent magnets, 5 polarity are identical is relative, two permanent magnets 5 are in the cavity of cylinder 2 with magnetic conduction sheet 4, and two permanent magnets 5 cooperate with the cavity clearance of cylinder 2 with the vibrations part that magnetic conduction sheet 4 constitutes.Be with a magnetic guiding loop 3 at the middle part on cylinder 2 surfaces, coil 6 separated into two parts are wrapped on the surface of cylinder 2 of magnetic guiding loop 3 both sides, and the housing 1 that the outside of cylinder 2 is with is two.

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.
