How the vibration component 4 illustrated in the present embodiment below in conjunction with accompanying drawing is hung and to be fixed in described installing space by described elastic supporting member for supporting optical member 3, and described elastic supporting member for supporting optical member 3 has the characteristics of high damping.In Figure 2-4, described elastic supporting member for supporting optical member 3 comprises after minute body formed having interconnective the first brace 31 of a part and the second brace 32 at least, form the strain gap between the part do not connected of described the first brace 31 and described the second brace 32, described vibrating motor has two elastic supporting member for supporting optical member 3, described first brace 31 of each described elastic supporting member for supporting optical member 3 and the sidewall 12 of described casing 1, 13 connect, described the second brace 32 is connected with described vibrating mass 41, described the first brace 31 has the first extension hook 311, described first extends hook 311 holds the bottom surface of described vibrating mass 41 and is welded and fixed with described bottom surface, and described vibrating mass 41 is not contacted with the bottom surface 14 of described casing 1, described the second brace 32 has the second extension hook 321, described first extends hook 321 blocks the sidewall of described vibrating mass 41 and is welded and fixed with the sidewall of described vibrating mass 41, and the sidewall that makes described vibrating mass 41 not with the sidewall 12 of described casing 1, 13 contacts.After installation, two described elastic supporting member for supporting optical member 3 lay respectively at the both sides of described vibrating mass 41, thereby described vibrating mass 41 is suspended in described casing 1, and the strain gap that the first brace 31 and the second brace 32 form is parallel to the bottom surface 14 of casing 1, is also that the distortion square parallel of elastic supporting member for supporting optical member 3 is in the bottom surface 14 of described casing 1.
The first brace 31 of elastic supporting member for supporting optical member 3 described above and the second brace 32 adopt a minute body formed mode moulding respectively, and then the part of the two is connected, and form the strain gap between the part do not connected.Due to described the first brace 31 and described the second brace 32 minutes, be connected again after body formed, therefore, during fabrication, can require according to the precompression of elastic supporting member for supporting optical member 3 link position of described the first brace 31 of design and the second brace 32, changed the deformation gap of the not coupling part formation of described the first brace 31 and the second brace 32, thereby make the vibrating motor of the present embodiment there is universality preferably.
At this, described the first brace 31 is welding with the fixed form of described casing 1, be specially laser welding, described the second brace 32 is also laser welding with the connected mode of described vibrating mass 41, certainly can also adopt other welding manners well known in the art maybe described vibrating mass 41 and the second brace 3 of described elastic supporting member for supporting optical member 3 can be fixed, and in vibrating mass 41 vibration processes, make it can not produce the fixed form of relative displacements with the second brace 3.Described elastic supporting member for supporting optical member 3 is spring.Described vibrating mass 41 adopts a kind of heavy alloy tungsten gold to manufacture, and density is greater than 17g/cm3, adopts the compacting sintering form to make, and can under very little volume, higher quality be arranged, thereby improves vibratory output.
Vibrating motor in the present embodiment, in order to realize frivolous purpose, in order to reach the purpose of the thickness that reduces casing 1, be arranged on the magnetic pole of two permanent magnets 42 on described vibrating mass 41 over against described coil 5, and the polarised direction over against the described magnetic pole of coil 5 is contrary, the magnetic pole polarised direction formed when as shown in Figure 6, coil 5 is switched on is parallel with the direction of magnetization of the permanent magnet 42 on vibrating mass 41.Particularly, the wherein magnetic pole of that is fixed on two permanent magnets 42 on described vibrating mass 41 is contrary with the magnetic pole of another piece, see Fig. 6, and the magnetic pole plane parallel of permanent magnet 42 is in the bottom surface 14 of casing 1, also be parallel to coil 5, that is, the N utmost point of permanent magnet 42 or the S utmost point are over against the bottom surface 14 of casing 1, also over against coil 5.
During coil 5 energising, it obtains alternating current from outside, electric current flows along the coiling direction of coil 5, the a certain moment, in Fig. 6, the magnetic field on the left side produces the electric current outside perpendicular to drawing, in Fig. 6, the magnetic field on the right produces perpendicular to drawing electric current inwards, simply illustrate each magnetic line of force direction in figure, according to left hand rule, it is F1 ' that magnetic field, the left side produces magnetic field force, direction to the right, it is F2 ' that magnetic field, the right produces magnetic field force, direction equally to the right, and both sizes are identical, therefore, the direction of the magnetic field force that whole coil 5 is subject to is for left, but, because coil 5 itself is positioned in the sidewall 12 of casing 1, on 13, therefore coil 5 can not move, but the relation due to active force and reaction force, two permanent magnets 42 are subject to respectively direction and F1 ', F1 and F2 effect that F2 ' opposite direction size is identical, and permanent magnet 42 together is suspended in installing space with vibrating mass 41, and the strain direction of elastic supporting member for supporting optical member 3 is parallel to the bottom surface 14 of casing 1, therefore, permanent magnet 42 and vibrating mass 41 1 coexist under the effect of magnetic field force to left movement (F1 in figure, the direction of arrow of F2).If the sense of current changes, permanent magnet 42 together moves right with vibrating mass 41, and the reciprocating motion that forms left and right with this, be parallel to the vibration of bottom surface.Because the direction of vibration of vibration component in vibrating motor is the bottom surface 14 that is parallel to casing 1, therefore, on the thickness direction of casing 1, does not need reserved larger gap to vibrate for it, thereby realized the frivolous and flat of motor.
As a kind of distortion of the present embodiment, two permanent magnets 42 can be made to one, the pole orientation of half is contrary with second half pole orientation, also can produce the effect identical with a upper execution mode.
Above-mentioned embodiment just is explained in detail the technical solution of the utility model; the utility model has more than and only is confined to above-described embodiment; those skilled in the art should be understood that; the above-mentioned principle of every foundation and the improvement of spirit on the utility model basis, substitute, all should be within protection range of the present utility model.
