Vibration exciter

The present disclosure discloses a vibration exciter comprising: a housing having a housing cavity, a stator assembly fixed in the housing, and a vibrator assembly housed in the housing cavity and driven to vibrate by the stator assembly; the stator assembly comprises a pole core fixedly attached to the inner side of the housing and a magnet fixedly attached to the side of the pole core that is back from the housing; the vibrator assembly includes a bracket housed in the housing cavity, a coil wound on the outside of the bracket, a counterweight fixed to the bracket, and a column assembly fixed to the end of the bracket and elastically connected to the housing; the bracket is a solid structure. When the coil is wound, it is wrapped around the bracket and column assembly, which is not easily deformed and improves the consistency of the coil shape.
