Please refer to Fig. 1 to Fig. 4.Fig. 1 is the schematic diagram of each assembly in the existing electromagnetic shaker 10; Fig. 2 is the schematic diagram after electromagnetic shaker 10 combinations; Fig. 3 is the schematic side view of electromagnetic shaker 10 along Fig. 2 Vertical Centre Line 3-3.Existing electromagnetic shaker 10 is a shell with housing 12A, 12B, and a runner 16 promptly is installed among housing 12A, the 12B in rotating mode, makes this runner 16 can flatly rotate (direction of arrow 25 indications in Fig. 2 just) around a vertical rotation axis 26 on horizontal plane 27; And Fig. 4 is the schematic top plan view of runner 16 along the direction of rotating shaft 26.In housing 12A, 12B, except rotating runner 16, also be provided with conductive brush 14A, 14B, and magnet 18A, 18B.And also be provided with

coil

20A, 20B on the runner 16 in addition, can conduct electricity to the conducting strip 22 of

coil

20A, 20B, and mass 15.Magnet 18A, 18B are fixed in the both sides, bottom side of housing 12B; The end of each brush 14A, 14B is fixed on the housing 12A, and the other end then contacts (as Fig. 2, shown in Figure 3 with conducting strip 22 on the runner 16; For the clear configuration that shows each assembly in the electromagnetic shaker 10, the part of housing 12A, 12B is removed among Fig. 2, Fig. 3).Brush 14A, 14B on associating housing 12A, the 12B and magnet 18A, 18B add conducting strip 22,

coil

20A and 20B on the runner 16, can be rotor with runner 16 just, realize out the function of a motor (similarly being d.c. motor).Shown in Fig. 2, Fig. 3, when brush 14A, 14B are electrically connected on one drive circuit 24 (similarly being a battery), the driving electric that drive circuit 24 provided just can be via brush 14A and 14B, conducting strip 22 and is transferred to

coil

20A, 20B on the runner 16, allow

coil

20A, 20B bring into play the function of electromagnet, the reciprocation of alternately repelling each other with magnet 18A, 18B on the housing 12B, inhaling mutually, drive runner 16 itself around rotating shaft 26 direction along arrow 25 rotate.

In order to bring into play the function of electromagnetic shaker 10 vibrations, runner 16 is designed to the shape (as shown in Figures 1 to 4) of non-circle symmetry especially, the relevant configuration of

coil

20A, 20B is countershaft 26 symmetries not also, one side of adding runner 16 also is provided with a mass 15 (being the object that a material density, weight differ from runner 16 basically), above-mentioned these counterbalance design all are to make the barycenter (mass centre) of runner 16 depart from rotating shaft 26 as far as possible, allow runner 16 become an eccentric runner.Just as shown in Figure 4, because special counterbalance design makes runner 16 become eccentric runner, projected position and its rotation rotating shaft 26 that centered on of its barycenter 19 on horizontal plane 27 has suitable departing from.So, when runner 16 rotated on horizontal plane 27, the unbalanced of its counterweight will produce the seismic wave of propagating along horizontal plane 27, and the direction of its vibration transmission is just shown in the arrow among Fig. 1 to Fig. 3 28.

Please refer to Fig. 5.Fig. 5 is the principle schematic of another kind of existing electromagnetic shaker 30.Be fixed with coil 34A, 34B in the housing 32 of electromagnetic shaker 30, opposite side then is provided with a rubber-like swing arm 36.One end of swing arm 36 is fixed on the housing 32, and the other end then is provided with a pendulum mallet 38 with magnetic.When coil 34A, 34B are electrically connected in one drive circuit 44 and during the driving electric that becomes when receiving, coil 34A, 34B just can bring into play the function of electromagnet, the magnetic force that changes in time and alternately pendulum mallet 38 is produced attraction or repels, allow the pendulum mallet 38 can be under the resiliency supported of swing arm 36 and swing back and forth between coil 34A, 34B, just the direction along arrow 40 swings back and forth.So, existing electromagnetic shaker 30 just can send seismic wave along the direction of arrow 42A, 42B, reaches the function of its vibrations.

By above description to existing electromagnetic shaker as can be known, the direction that existing electromagnetic shaker 10 and 30 sends seismic wave all limits to some extent, can not send multidirectional seismic wave.As shown in Figures 1 to 4, existing electromagnetic shaker 10 can only send the seismic wave of propagating along horizontal plane 27, can't send the seismic wave perpendicular to horizontal plane 27.That is to say that existing electromagnetic shaker 10 can't send seismic wave along the direction of rotating shaft 26.Similarly, the electromagnetic shaker 30 among Fig. 5 also can only send the seismic wave of vertical direction along arrow 42A, 42B, can't send the seismic wave of horizontal direction along arrow 46 (Fig. 5).Because these existing electromagnetic shakers all are restricted sending on the direction of seismic wave, also make the vibrations cue that it sent be attenuated easily, offset jointly.For instance, the existing electromagnetic shaker 30 of picture in Fig. 5, if the user carry, when wearing the electronic installation that is equiped with electromagnetic shaker 30, just make the two ends up and down of its housing 32 be subjected to the extruding of arrow 42B, 42A direction respectively, existing electromagnetic shaker 30 will be cancelled or decay in the vibrations that arrow 42A, 42B send, and can't send the vibrations cue effectively.In like manner, concerning the existing electromagnetic shaker 10 among Fig. 1 to Fig. 4, if the user is when carrying the electronic installation that is equiped with electromagnetic shaker 10, make the housing of electromagnetic shaker 10 be subjected to the extruding of horizontal plane direction all around, the seismic wave that electromagnetic shaker 10 sends in the horizontal plane direction also will be cancelled, and can't effectively send the vibrations cue.

Summary of the invention

Therefore, main purpose of the present invention promptly is to provide a kind of electromagnetic shaker and related electronic device that can send seismic wave in a plurality of different directions, to overcome the shortcoming of prior art.

In the present invention, be the seismic wave that produces the horizontal plane direction with the eccentric runner that horizontally rotates around rotating shaft, produce seismic wave with interlinked mechanism again perpendicular to this horizontal direction.In one embodiment of this invention, this interlinked mechanism is one around rotating shaft, has the interlock rail that height rises and falls, and when runner rotates around rotating shaft, will move up and down along with this interlock rail, produces seismic wave perpendicular to this horizontal plane along rotor shaft direction.In another embodiment of the present invention, this interlinked mechanism can be realized its purpose by electromagnet; This electromagnet can be on the direction of rotating shaft the runner of attraction/repulsion alternately with magnetic, drive runner and move up and down, also can produce seismic wave perpendicular to horizontal plane.In addition, the auxiliary body that the present invention also can slide up and down along rotor shaft direction in the housing sidewall setting of electromagnetic shaker then is provided with the interlock rail that height rises and falls on the runner.When runner rotated, the auxiliary body that is embedded in the interlock rail will slide up and down jointly, also can make electromagnetic shaker of the present invention be produced the seismic wave of propagating in vertical direction.No matter be which kind of embodiment, electromagnetic shaker of the present invention can both send the omnirange seismic wave of the level of having concurrently, vertical direction.When the present invention is applied to the electronic installation of mobile phone, calling set etc., no matter how the user carries electronic installation, the comprehensive vibrations that electromagnetic shaker of the present invention produced all are difficult for being squeezed and are cancelled, and can send the vibrations cue effectively, convenient user's work, life.

auxiliary body

108A, 108B also just rise and up slide jointly (just sliding along the direction of arrow 126A) along with the track of interlock rail 118, just the situation shown in the state Tb.By the time runner 96 rotates 180 degree backs (just rotating 90 degree backs again at state Tb) by state Ta, and the spiral rising trace of interlock rail 118 is also just driving

auxiliary body

108A, 108B and rising to peak, shown in state Tc.But, when having arrived state Tc, spiralling track is also ended in the interlock rail 118, and turning to the track of rapid drawdown, this also makes

auxiliary body

108A, 108B to return back to state Ta (elastic force of

spring

114A, 114B can guarantee that

auxiliary body

108A, 108B return back to the position among the state Ta apace) in moment by state Tc apace.So,

auxiliary body

108A, 108B just can send the seismic wave of vertical direction when returning back to state Ta by state Tc, just the seismic wave of propagating along arrow 126A, 126B.In other words, rotate the horizontal direction seismic wave that is produced by eccentric runner 96, add the vertical direction seismic wave that runner 96 drives

auxiliary body
