Document Type and Number:
WIPO Patent Application WO/2021/000090
Kind Code:
A1
Abstract:
Disclosed is a vibration electric motor, comprising a shell (1), a vibrator (3), and a stator (2), wherein the vibrator (3) comprises a magnetic circuit structure (33) used for vibration, the stator (2) comprises a coil (21) used for driving the magnetic circuit structure (33) to vibrate, the wire winding plane of the coil (21) is parallel to the vibration direction of the vibrator (3), the magnetic circuit structure (33) comprises a first magnetic steel set (333) arranged on one side of the coil (21) in the vibration direction of the vibrator (3) and a second magnetic steel set (335) arranged on the other side of the coil (21) in the vibration direction of the vibrator (3), the first magnetic steel set (333) and the second magnetic steel set (335) are symmetrically arranged, each of the first magnetic steel set (333) and the second magnetic steel set (335) comprises a plurality of pieces of magnetic steel arranged in an array manner, the magnetic steel is magnetized in the direction perpendicular to the vibration direction of the vibrator (3), the magnetizing directions of every two adjacent pieces of magnetic steel are opposite, and the pieces of magnetic steel, opposite in position, of the first magnetic steel set (333) and the second magnetic steel set (335) have the same magnetizing direction. The vibration electric motor increases the drive and enables the response speed to be fast and the vibration effect to be better.
