ABSTRACT:
A vibration device is provided. The vibration device includes a case, a vibrator, a coil, and a spring. The vibrator is disposed inside the case and including a magnet, a yoke, and a weight. The coil is supported by the case. The spring allows the vibrator to be elastically supported by the case. The spring includes a first coupling portion coupled to the vibrator, a second coupling portion coupled to the case, and a connecting portion connecting the first coupling portion to the second coupling portion. The second coupling portion is disposed on a concentric circle with respect to a center of the first coupling portion. A region in which the second coupling portion is disposed on the concentric circle ranges from 40% or more to less than 100% of a total region of the concentric circle.
