Abstract:
A vibration generator includes a circumferential wall portion, a vibrating body arranged inside the circumferential wall portion in an opposing relationship with a coil and configured to reciprocatingly vibrate in one direction, a band-shaped leaf spring arranged between the vibrating body and the circumferential wall portion to support the vibrating body on the circumferential wall portion, and a damper member including a base portion attached to one of the vibrating body and the leaf spring and a tip end portion extending toward the other of the vibrating body and the leaf spring. The tip end portion of the damper member makes sliding contact with the leaf sprig or the vibrating body.
