Abstract:
A vibration motor includes a stationary portion including a casing and a coil; a vibrator including a magnet, and supported to be capable of vibrating in one direction with respect to the stationary portion; and an elastic member arranged between the stationary portion and the vibrator. The magnet is arranged on an upper side of the coil in a vertical direction perpendicular to the one direction. The elastic member includes a fixing portion fixed to a side surface of the vibrator, and a top plate portion joined to the fixing portion, and fixed to an upper surface of the vibrator. The top plate portion is arranged opposite to the magnet in the vertical direction.
