摘要： A vibration actuator includes a coil that extends in a vibration direction and has a flat shape and a magnet that extends in the vibration direction and has a flat shape, so that a case can be made flat or low profile. A weight portion is supported by a shaft, so that, when a drop impact is applied, the weight portion can move along the shaft and the weight portion is not freely moved in the case. A coil spring is disposed between a spring receiving portion and a weight portion. Therefore there is no unnecessary space in the case, so that space can be saved and the vibration actuator can be made compact.
