Along with consumption electronic products develop towards frivolous direction, the various components and parts of its inside also need to adapt to frivolous trend, meanwhile also will keep even strengthen its performance.Motor is not routine yet, use linear vibration electric motor more and that vibrating motor better performances is a flat at present, as shown in Figure 1, the linear vibration electric motor 10 ' of correlation technique mainly comprises the pedestal 11 ' that is provided with spatial accommodation, be positioned at coil 12 ' on the pedestal 11 ', be connected in the resilient support part 13 ' of pedestal 11 ', be suspended on the balancing weight 14 ' and the permanent magnet 15 ' of spatial accommodation by elastic supporting member for supporting optical member 13 ', coil 12 ' is positioned at the below centre of permanent magnet 15 ', and the two is contained in the spatial accommodation of pedestal 11 ' in the lump.Wherein, balancing weight 14 ' is provided with link 140 '.
Elastic supporting member for supporting optical member 13 ' is the key core parts of whole linear vibration electric motor, and the change of its shape and different outside connected modes all can make a big impact to linear vibration electric motor performance and the useful life when working.The elastic supporting member for supporting optical member 13 ' of the linear vibration electric motor 10 ' of correlation technique comprises the fixed part 130 ' continuous with pedestal, is reached by elasticity arm 131 ' connecting portion 132 ' that extend and that be connected with the link 140 ' of balancing weight 14 ' by fixed part 130 ' the extended elasticity arm 131 '.Elastic supporting member for supporting optical member 13 ' links to each other with balancing weight 14 ' by connecting portion 132 '.
Yet the elastic supporting member for supporting optical member of the linear vibration electric motor of correlation technique is provided with four, and its assembling is loaded down with trivial details, and the effective deformation zone of each elastic supporting member for supporting optical member is little, and elastic force is also little naturally, thereby influences vibrating effect.Under identical amplitude situation, the life-span of elastic supporting member for supporting optical member is short.The vibrating effect and the useful life of vibrating motor certainly will have been limited like this.
Therefore, be necessary to propose the assembling that a kind of new technical scheme is simplified the elastic supporting member for supporting optical member of linear vibration electric motor, improve its vibrating effect and increase its useful life.
[utility model content]
It is simple that the technical problem that the utility model need solve provides a kind of assembling, and vibrating effect is good, the linear vibration electric motor of long service life.
According to above-mentioned technical problem, designed a kind of linear vibration electric motor, its objective is such realization: a kind of linear vibration electric motor comprises balancing weight and supports the elastic supporting member for supporting optical member of described balancing weight.Described elastic supporting member for supporting optical member be provided with the junction surface that is connected in described balancing weight, by described junction surface bend extended first elasticity arm, by first elasticity arm extend and towards described first elasticity arm and strain direction for towards described first elasticity arm or away from second elasticity arm of described first elasticity arm and by the extended fixed arm of described second elasticity arm.Wherein, described balancing weight is provided with some sides, and it surrounds the housing of described balancing weight jointly, and the junction of adjacent two described sides is provided with fixed angles.Described elastic supporting member for supporting optical member is provided with at least two, and the junction surface of at least two described elastic supporting member for supporting optical member is fixed on the fixed angles place at two diagonal angles of described housing respectively.Described first elasticity arm extends to the other end by an end of housing one side along this side directions.
Preferably, described junction surface is fixed on the non-conterminous fixed angular positions of described housing respectively.
Preferably, the described junction surface part of described adjacent dual-side that is sticked respectively.
Linear vibration electric motor of the present utility model, its elastic supporting member for supporting optical member assembling is simple, and vibrating effect is good, long service life.

[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 2, a kind of linear vibration electric motor 1 comprises balancing weight 2 and the elastic supporting member for supporting optical member 3 that supports described balancing weight 2.
As shown in Figure 3-4, elastic supporting member for supporting optical member 3 be provided with the junction surface 35 that is connected in balancing weight 2, by extended first elasticity arm 33 of junction surface 35 bendings, by first elasticity arm 33 extend and towards first elasticity arm 33 and strain direction for towards first elasticity arm 33 or away from second elasticity arm 32 of first elasticity arm 33 and by second elasticity arm, 32 extended fixed arms 31.Fixed arm 31 is to be connected with pedestal shown in Figure 24, fixing whole elastic supporting member for supporting optical member 3.Wherein, balancing weight 2 is provided with some sides 36, and it surrounds the housing (not label) of balancing weight 2 jointly, and the junction of adjacent two described sides 36 is provided with fixed angles 37.Elastic supporting member for supporting optical member 3 is provided with at least two, and the junction surface 35 of at least two elastic supporting member for supporting optical member 3 is separately fixed at fixed angles 37 places at two diagonal angles of described housing.First elasticity arm 33 by housing wherein an end of a side 36 extend to the other end along these side 36 directions.
