  • Linear vibration motor with at least couple linear movement support shafts of the vibrator
    Patent number: 11664712
    Abstract: A linear vibration motor and an electronic device are provided. The linear vibration motor comprises: a magnetic conductive body; a vibrator comprising a permanent magnet; and a linear movement support, wherein the vibrator is mounted on the linear movement support to move along a linear movement path delimited by the linear movement support, wherein the magnetic conductive body is provided in a direction of the linear movement path near the vibrator for interacting with the permanent magnet, such that the vibrator tends towards a balanced position in the linear movement path in a non-activated state, wherein the magnetic conductive body is made of soft magnetic material, wherein the linear movement support comprises at least one guide shaft along which the vibrator can move axially, and wherein the magnetic conductive body is a magnetic conductive ring surrounding the vibrator.
