Vibration motor

A vibration motor comprising:

• a housing with a containment space;
• a vibration component contained in the containment space, including a mass block spaced apart from the housing, a magnet assembly fixed to the mass block, and an elastic component supporting the mass block in the containment space;
• and
• a stator component;
• wherein
• the magnet assembly includes a magnet fixed to the mass block, and the magnet has a magnetizing magnetic circuit with a Halbach array structure;
• when the magnetizing magnetic circuit is a five-pole magnetizing magnetic circuit and the magnet is magnetized segmentally, the magnet includes a first sub-magnet, a second sub-magnet, a third sub-magnet, a fourth sub-magnet, and a fifth sub-magnet arranged in sequence along a vibration direction of the vibration component;
• magnetization directions of the first sub-magnet and the fifth sub-magnet are the same and both are magnetized along a direction vertical to a vibration direction, a magnetization direction of the third sub-magnet is opposite to that of the first sub-magnet and is magnetized along the direction vertical to the vibration direction, and magnetization directions of the second sub-magnet and the fourth sub-magnet are opposite to each other and both are magnetized along the vibration direction.
