Abstract:
A vibration exciter, comprising a housing having an accommodating cavity, a stator assembly assembled in the housing, and a vibrator assembly assembled in the accommodating cavity and driven by the stator assembly to vibrate. The stator assembly comprises a pole core (21) fixed to the inner side of the housing and magnetic steel (22) fixed to the side of the pole core (21) away from the housing; the vibrator assembly comprises a frame (31) elastically connected to the housing, counterweight blocks (321, 322) fixed to the frame (31), and a coil (34) wound around the outer side of the frame (31); the frame (31) is integrally formed and is of a solid structure; the coil (34) is wound on the frame (31) in a concentrated manner. Because the frame (31) is of an integrally formed solid structure, when the coil (34) is wound, the frame (31) is not prone to deformation, the shape of the coil (34) can be controlled, and the coil (34) has a good shape.
