Abstract
An electromagnetic vibrator includes a movable body producing vibration by revolving motion or reciprocating motion with respect to its center axis through being powered from the outside. The vibrator also includes an outer shell supporting the moving body and having two mounting faces, one being vertical and the other being parallel to the center axis. A portable device employs this electromagnetic vibrator. This structure allows the portable device to gain vibration in either direction, thereby increasing the versatility of the device. When a plurality of the electromagnetic vibrators are mounted to a device with their center axes in different directions or in the same direction, vertical and lateral vibrations can be produced at the same time, so that the device owns complex vibration modes and performs versatile functions.
