  • the coil unit 130 is provided between the vibrating body 110 and the rotating shaft portion (shaft hole 151), but the present invention is not limited to this, and the vibrating body 110 and the rotating shaft portion (shaft hole 151)
  • a magnet unit 140 may be provided between the two.
  • the vibrating body 110 is suspended by the elastic member 120, but the present invention is not limited to this, and the vibrating body 110 is supported by the elastic member 120 at least if the vibrating body 110 can vibrate in the left-right direction. It may be configured not to be suspended.
