Permanent magnets are embedded in the counterweight block, the base is provided with a plurality of side walls and a bottom wall perpendicular to the side walls, the coil is arranged on the bottom wall and positioned in the middle below the permanent magnets, the counterweight block comprises a body and bosses, the bosses extend out of the body to two ends respectively along the direction of vibration in a derived manner, and the height of each boss is larger than the distance from the body to the side walls when the elastic supporting parts are in maximum deformation. By the aid of the bosses arranged on the counterweight block in the vibration direction, when the vibration motor falls off, over-large deformation of elastic sheets caused by suffered impact is avoided, so that the elastic sheets are protected from damage.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of vibrating motor that is applicable to most of electronic products.
Background technology
Along with development of electronic technology, the portable consumer electronic product more and more is subjected to pursuing of people, as mobile phone, handheld device, guider or palm multimedia entertainment equipment etc., generally all can use vibrating motor and do system feedback, such as vibrational feedback of the incoming call prompting of mobile phone, information indicating, navigation hint, game machine etc.Use so widely, just require the performance height of vibrating motor, long service life.
Be applied to the vibrating motor in the portable consumer electronic product at present, when electronic product drops because of carelessness, cause the excessive shell fragment that damages of shell fragment deformation in the vibrating motor easily because of the impulsive force in the vibrating motor is excessive.
Therefore, be necessary to provide a kind of new vibrating motor to overcome above-mentioned defective.
The utility model content
The purpose of this utility model is to solve above-mentioned vibrating motor shell fragment of inside when dropping and is hit that power is excessive to cause deformation excessive, thereby damages the deficiency of shell fragment, and a kind of vibrating motor is provided:
A kind of vibrating motor, it comprises loam cake, cooperate the pedestal that forms spatial accommodation with loam cake, be contained in the spatial accommodation and the relative static coil of pedestal, be connected in the elastic supporting member for supporting optical member of pedestal, be suspended on balancing weight in the spatial accommodation by elastic supporting member for supporting optical member, balancing weight is embedded with permanent magnet, pedestal is provided with some sidewalls and perpendicular to the diapire of sidewall, coil is arranged on the diapire and is positioned at the bottom center position of permanent magnet, described balancing weight comprise body and from described body along its direction of vibration to the two ends extended boss of deriving respectively, the distance of body between sidewall when the height of described boss is greater than elastic supporting member for supporting optical member generation largest deformation.
Preferably, when balancing weight was static, the most significant digit when vibrating greater than balancing weight along the distance of its direction of vibration convex platform between sidewall was moved.
Preferably, between described elastic supporting member for supporting optical member is arranged on balancing weight body and pedestal sidewall on the balancing weight direction of vibration.
Preferably, described boss is arranged on and does not press from both sides an end of establishing elastic supporting member for supporting optical member between balancing weight body and the sidewall.
The beneficial effects of the utility model are: by on the direction of vibration of balancing weight boss being set, like this, when product falls, can not causing shell fragment deformation excessive because the impulsive force that is subjected to is excessive, thereby reach the not impaired purpose of protection shell fragment.
Description of drawings
Fig. 1 is the three-dimensional exploded view of the utility model vibrating motor;
Fig. 2 is the cutaway view after the vibrating motor assembling among Fig. 1;
Fig. 3 is the front view that lacks loam cake among Fig. 1 after the vibrating motor assembling.
Embodiment
The utility model is described in further detail below in conjunction with drawings and embodiments.
As depicted in figs. 1 and 2, the utility model provides a kind of vibrating motor 1, it comprises loam cake 10, cooperate the pedestal 11 that forms spatial accommodation with loam cake 10, be contained in the spatial accommodation and the static coil 12 of pedestal 11 relatively, be connected in the elastic supporting member for supporting optical member 13 of pedestal 11, the pcb board 16 that is suspended on the balancing weight 14 in the spatial accommodation and is arranged on pedestal 11 bottoms by elastic supporting member for supporting optical member 13, balancing weight 14 is embedded with permanent magnet 15, pedestal 11 is provided with some sidewalls 111 and perpendicular to the diapire 112 of sidewall 111, coil 12 is arranged on the diapire 112 and is positioned at the bottom center position of permanent magnet 15.Described vibrating motor 1 gives coil 12 energisings by pcb board 16, coil 12 produces magnetic field, thereby allowing coil 12 produce with permanent magnet 15 repels, 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 Figure 3, described balancing weight 14 comprise body 141 and from described body 141 along its direction of vibration X-X to the two ends extended boss 142 of deriving respectively, along on described balancing weight 14 direction of vibration, the distance of body 141 between sidewall 111 when the height H of described boss 142 is greater than elastic supporting member for supporting optical member 13 generation largest deformations, when balancing weight 14 is static, move along the most significant digit of the distance of its direction of vibration X-X convex platform 142 between sidewall 111 during greater than balancing weight 14 vibrations.The height H of described boss 142 is the height of boss 142 relative bodies 141, the most significant digit during 14 vibrations of described balancing weight move be meant vibrating motor 1 when operate as normal the position of balancing weight 14 when static to the displacement farthest that departs from described position.
Between described elastic supporting member for supporting optical member 13 is arranged on balancing weight body 141 and pedestal sidewall 111 on the balancing weight 14 direction of vibration X-X, and be fixed on balancing weight body 141 and the pedestal sidewall 111.Described boss 142 is arranged on and does not press from both sides an end of establishing elastic supporting member for supporting optical member 13 between balancing weight body 141 and the sidewall 111.
By two ends boss 142 is set at balancing weight 14; like this; when vibrating motor 1 is subjected to very big impulsive force when dropping; but being subjected to the protection of boss 142, the elastic supporting member for supporting optical member 13 in it can not produce destructive deformation; thereby reached the purpose of protection elastic supporting member for supporting optical member 13, promoted the useful life of vibrating motor 1 effectively.
Above-described only is better embodiment of the present 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 protection range of the present utility model.
