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.

DETAILED DESCRIPTION The present invention addresses the problems discussed above and aims to contribute to realizing such devices having well-advanced.
An electromagnetic vibrator of the present invention comprises the following elements: (a) a movable body revolving or reciprocating with respect to a center axis by being powered from outside; and (b) an outer shell supporting the movable body and including two mounting faces--one is vertical and another is parallel to the center axis.
A portable device of the present invention includes the electromagnetic vibrator discussed above.
This structure allows the vibrator to generate vibration in either direction, and contribute to increasing versatility of the device.
Another portable device of the present invention has a plurality of electromagnetic vibrators in which movable bodies perform either one of revolving or reciprocating movement with respect to the center axes to generate vibration.
The plurality of electromagnetic vibrators are mounted to the device with their center axes lying in specific different directions or in the same direction.
This structure allows vibrators to have complex vibration modes such as generating vertical and lateral vibrations at the same time, and contribute to realizing a device of well-advanced functions.
