Specific embodiment
The present invention is described further with specific embodiment with reference to the accompanying drawing:
Embodiment as depicted in figs. 1 and 2 is a kind of flat vibration motor of ultrathin, including lower bracket components 1, is set to
Vibration component 2 on lower bracket components and the casing 3 to match with lower bracket components；As shown in Fig. 2, the lower bracket components packet
Bottom bracket 11 is included, coil 12 and FPC pad 13 on bottom bracket；As shown in figure 3, the vibration component includes mass block
21,4 magnet steel 22 and 4 elastic slices 23；The mass block is equipped with 4 through-hole 211 and 4 grooves 212；As shown in Figure 1, each
Elastic slice includes the first fixing end 231, the second fixing end 232, the arc-like sheet being all connected with the first fixing end and the second fixing end
233；Each through-hole is symmetrically distributed on mass block, and each groove is symmetrically distributed on the outer edge of mass block；Each
One fixing end is welded on each groove, and each magnet steel is symmetrically embedded in each through-hole by glue；It welds at the both ends of coil
On FPC pad, FPC pad plays the role of turn-on power, and each magnet steel is respectively positioned on the surface of coil；Casing plays support
The effect of motor operation and protection internal structure of motor.
