摘要： A haptic actuator includes a housing having a ferromagnetic wall. The ferromagnetic wall has a set of one or more half shear ferromagnetic features protruding from the ferromagnetic wall into the housing. A movable magnet is positioned within the housing. A pair of springs, respectively attached to opposite sides of the housing and opposite ends of the movable magnet, bias the movable magnet toward a position of rest between the pair of springs. An electric coil is attached to the set of one or more half shear ferromagnetic features and positioned between the movable magnet and the set of one or more half shear ferromagnetic features.

摘要： A vibrator support structure, a vibration motor including the vibrator support structure, and an electronic device including the vibration motor are provided. The vibrator support structure includes a housing, a vibrator, and a first support member. The vibrator is slidable in a first direction D1 and a second direction D2 that crosses the first direction D1. The vibrator is supported within the housing by the first support member, which includes a first deformation portion and a first engagement portion. The first deformation portion undergoes elastic deformation associated with vibrations of the vibrator in the first direction D1. The first engagement portion engages with the vibrator in such a manner that the vibrator produces a sliding motion associated with vibrations of the vibrator in the second direction D2.
