VIBRATION DEVICE AND VIBRATION METHOD THEREOF

Abstract: in the ic card, the first vibration pattern of the piezoelectric element when the separation distance between the reader-writer and the power receiving unit is short is different from the second vibration pattern of the piezoelectric element when the separation distance is longer. therefore, the user can sense the difference in distance between the ic card and the reader-writer from the difference in vibration pattern. that is, the user may obtain information about the above separation distance, and increase of information communicated to the user is implemented.
