Vibration generating device with movable case including magnets and disposed inside stationary case

Abstract

A vibration generating device includes a fixed case; a movable body disposed inside the fixed case; a support member configured to support the movable body with respect to the fixed case such that the movable body is configured to vibrate along a first direction; and a coil attached to the fixed case. The movable body includes a magnetic field generator configured to generate a magnetic field along a second direction perpendicular to the first direction, and a movable case configured to accommodate the magnetic field generator. A plurality of magnetic members including a permanent magnet constitute the magnetic field generator. The plurality of magnetic members are accommodated in the movable case such that the plurality of magnetic members are stacked in the first direction and are not movable relative to each other. A plurality of movable case members separable in the first direction constitute the movable case.
