`(57) Abstract: Provided is ath in linear vibration motor that suppresses the
`occurrence of operating noise. A linear Vibration motor 1 is provided with:
`a stator 10; a movable element 20 elastically supported by the stator 10 so
`as to freely vibrate along an axial direction; and a drive unit 30 that has a
`coil 31 provided to the stator 10 and a driving magnet 32 provided to the
`movable element 20, and that causes the movable element 20 to vibrate in a
`a<3oJ
`K
`reciprocating manner along the axial direction Via current conduction to the
`/\ [732(30)
`coil 31 While attracting the driving magnct 32 via a magnetic body (support
`\Zfl/
`22(20) plate 1 1) disposed on the stator sidc ofthc coil 31. The stator 10 is providcd
`
`with a stationary magnet 14 that is magnetized in a direction intersecting
`the axial direction. The movable element 20 is provided With a movable
`V2190) magnet 24 that faces the stationary magnet 14 While being repelled thereby.
