Vibration motor and haptic device

Vibration motor and haptic device

A vibration motor includes a stationary portion and a movable portion vibrable in an axis direction with respect to the stationary portion. The stationary portion includes a coil and a housing. The housing includes a first region expanding in a first direction orthogonal to the axis direction, and a...

description A vibration motor includes a stationary portion and a movable portion vibrable in an axis direction with respect to the stationary portion. The stationary portion includes a coil and a housing. The housing includes a first region expanding in a first direction orthogonal to the axis direction, and a second region disposed on one side in a second direction orthogonal to the axis direction and the first direction relative to the first region and expanding in the first direction. In a cross-section across the axis direction, a distance in the second direction between the second region and the first region is longest at a center in the first direction of the first region. In the cross-section, a shape formed by the first and second regions is asymmetric with respect to an axis extending parallel to the first direction through a center of the housing in the second direction.
