Title:
LINEAR VIBRATION MOTOR AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/166012
Kind Code:
A1
Abstract:
A linear vibration motor and an electronic device. The motor comprises: a magnetic body (201); a rotor (301), comprising a permanent magnet (302); linear movement support bodies (104, 105). The rotor (301) is mounted on the linear movement support bodies (104, 105), and moves along a linear movement path defined by the linear movement support bodies (104, 105). The magnetic body (201) is arranged along the direction of the linear movement path near to the rotor (301) so as to interact with the permanent magnet (302), thereby enabling the rotor (301) to tend towards a balanced position on the linear movement path when in a non-excited state. The material of the magnetic body (201) is a soft magnetic material. The present technical solution allows for the omission of mechanical springs.
