[embodiment]
Below in conjunction with accompanying drawing and execution mode the utility model is described further.
As depicted in figs. 1 and 2; The utility model provides a kind of vibrating motor 1; The pcb board 16 that it comprises the pedestal 11 that is provided with sidewall 111 and diapire 112, cooperates the loam cake 10 that forms spatial accommodation with pedestal 11, be contained in the static coil 12 of the interior also relative pedestal of spatial accommodation 11, be connected in the elastic supporting member for supporting optical member 13 of pedestal 11, be suspended on the balancing weight 14 in the spatial accommodation and be arranged on pedestal 11 bottoms by elastic supporting member for supporting optical member 13; Balancing weight 14 is embedded with permanent magnet 15, and coil 12 is arranged on the diapire 112 and is positioned at the lower position of permanent magnet 15.Said vibrating motor 1 gives coil 12 energisings through pcb board 16; Coil 12 generation magnetic fields; Repel thereby let coil 12 produce with permanent magnet 15, and permanent magnet 15 is fixed in the balancing weight 14, balancing weight 14 is supported by elastic supporting member for supporting optical member 13 again; So permanent magnet 15 drives balancing weight 14 double vibrationses, thereby realize the vibration purpose of vibrating motor 1.
As shown in figures 1 and 3; Said elastic supporting member for supporting optical member 13 comprises the elastically-deformable deformations 131 of generation and is connected deformations 131 and is fixed on the fixed part 132 on balancing weight 14 sidewalls; Said vibrating motor 1 also is provided with stiffening piece 17; Said stiffening piece 17 is provided with weld tabs 171 that spot welding is fixed on balancing weight 14 upper and lower surfaces and is connected said weld tabs 171 and is attached to the brace 172 on said fixed part 132 surfaces; Said brace 172 vertical weld tabs 171, said brace 172 extends catch 173 along deformations 131 surfaces to said deformations 131 directions, on the direction perpendicular to balancing weight 17 direction of vibration X-X; The length of catch 173 is not more than the half the of brace 172 width, but the concrete length of catch 173 will be decided according to the stress distribution situation of reality.
When vibrating motor 1 work, elastic supporting member for supporting optical member 13 is along with balancing weight 14 produces toward complex deformation, and deformations 131 takes place toward complex deformation near the position of fixed part 132 is same; And original owing to there is not the existence of catch 173, this place is easy to fracture, thereby influences the intensity of elastic supporting member for supporting optical member 13; Influence the useful life of vibrating motor 1; Extend catch 173 from brace 172 to deformations 131 now, the relative stiffening piece 17 of the rigidity of catch 173 a little less than, like this; Catch 173 is with elastic supporting member for supporting optical member 13 past complex deformations; Thereby effectively shared the stress of deformations 131, guaranteed the intensity of elastic supporting member for supporting optical member 13 when vibrating motor 1 work thus, made vibrating motor 1 more reliable near the position of fixed part 132.
Above-described only is the preferred embodiments of the utility model; Should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; Can also make improvement, but these all belong to the protection range of the utility model.
