Abstract
The invention provides a vibration motor having a housing assembly, an elastic connector, a pole plate, a plurality of magnets and a plurality of coils. The coils and the magnets are matched to drive the pole plate to move in at least two directions within the housing assembly. The coils are arranged on the outer side of the pole plate and fixed on the housing assembly so as to be suitable for a small-size vibration motor, then limitation of coil sizes is effectively avoided. Arrangement of the coils is facilitated, and process flows of the vibration motor during specific assembly can be optimized.
