<P>PROBLEM TO BE SOLVED: To enlarge a vibration to be sensed by a user concerning a mobile apparatus such as a portable telephone with a vibration function. <P>SOLUTION: Vibration motors 2, 3 are mounted on a housing 1 so as to allow mutual shafts to be nearly in parallel with each other. When the direction of a first centrifugal force to be generated with the rotation of a weight 2a becomes vertical to a plane including the shafts of the vibration motors 2, 3, a control part 8 controls the vibration motors 2, 3 thereby to allow the direction of a second centrifugal force to be generated with the rotation of a weight 3a to be nearly the opposite direction with respect to the plane. Further, when the direction of the first centrifugal force becomes in parallel with the plane, the control part 8 drives the vibration motors 2, 3 thereby to allow the direction of the second centrifugal force to be the same as the direction of the first centrifugal force. <P>COPYRIGHT: (C)2013,JPO&INPIT |
