Further, which further includes two bayonets 44, and two bayonets are respectively arranged at the both sides of connecting portion, and two bayonets are located at bullet On the non-vibration direction of spring.

Further, the connecting portion is connected with elastic portion by arc-shaped transition area 47.

The utility model has the advantage of：

Spring described in the utility model is by being repeatedly bent to form, when being compressed, the stroke of the spring of reduction, and drop The low stress of spring, improves the service life that spring uses.

The bending number and windowing size, reconfigurable of spring described in the utility model, improve the adaptation of spring Property.

Brief description of the drawings

In order to make the purpose of this utility model, technical solution and advantage clearer, below in conjunction with attached drawing to this practicality It is new to be described in further detail, wherein：

Fig. 1 is the new exploded view of this reality；

Fig. 2 is the structure chart of spring；

Fig. 3 is the side view of spring.

Embodiment

Below with reference to attached drawing, the preferred embodiment of the utility model is described in detail；It is it should be appreciated that it is preferred that real Example is applied only for illustrating the utility model, rather than in order to limit the scope of protection of the utility model.

It is provided by the utility model can mover assembly can be applied to portable consumer electron-like device, such as mobile phone, the palm Game player, guider, tablet computer or palm multimedia entertainment equipment etc..

A kind of two-stage linear vibration motor can mover assembly, including iron core 1, coil 2, two spacing fixed blocks 3, springs 4 And FPC5, the coil is around being located on iron core；Two elastic portions of the spring are located at the both ends of coil respectively, positioned at spring On direction of vibration；Two spacing fixed blocks are located at the both sides of spring respectively, on the non-vibration direction of spring；The FPC's One end is fixed on one of them spacing fixed block and is connected with coil, input terminal of the other end as external electric signal.

If the utility model be equipped with can mover assembly both sides the magnet steel to magnetize through 45 degree, it is possible to achieve two sides To vibration.45 degree of angles are done to magnet steel to magnetize and (magnet steel is diagonally filled corresponding N, S pole), when allowing iron core with magnet steel interaction The component of the power of performance Y-direction and Z-direction, can when the change frequency of coil current is consistent with the resonant frequency of spring Y-direction Mover assembly does Y-direction reciprocating motion, and the vibration sense that motor produces Y-direction is felt；When the change frequency and spring Z-direction of coil current Resonant frequency it is consistent when, can mover assembly do Z-direction reciprocating motion, the vibration sense that motor produces Z-direction is felt.
