  • Vibration motor with magnetic steel assembly and elastic support between pillars
    Patent number: 11515774
    Abstract: The present disclosure discloses a vibration motor including a fixing frame, a suspending frame, an iron core, a drive coil, an elastic support and a magnetic steel assembly. The magnetic steel assembly includes a first magnetic steel, a second magnetic steel and a third magnetic steel that are superimposed in order. Polarity directions of the first magnetic steel and third magnetic steel are parallel with a central axis of the drive coil. A side of the first magnetic steel that the side facing the second magnetic steel has the same polarity with a side of the third magnetic steel that the side facing the second magnetic steel. The vibration motor can generate two magnetic loops whose magnetic forces increases drive force of the vibration motor.
