VIBRATION MOUSE THAT PROVIDE REAL TIME VIBRATION FEEDBACK

摘要

The present invention relates to a vibration mouse which provides vibration feedback corresponding to visual information. A piezoelectric vibration body (6) is formed by integrating a piezoelectric device layer (8), having a piezoelectric effect, with a center electrode plate (10). Both end portions of the piezoelectric vibration body (6) are fixated to generate vibration by vertical bending displacement. At least one actuator (4) to which a weight piece (12) for increasing vibration of the piezoelectric vibration body (6) is attached is installed on the inside of a body (2) of the vibration mouse (1) so that the vibration mouse can respond to fast variable vibration in a high frequency band in real time. Therefore, the vibration mouse provides realistic sensation to a user by transmitting various vibration amounts corresponding to the visual information in a quick vibration response. Accordingly, the vibration mouse can transmit vibration sensation with the visual information at a high response speed and thus enables a user to have synchronization sensation. In addition, the vibration mouse can transmit various vibration patterns such intensive vibration and subtle vibration by adjusting a vibration amount of the actuator (4) based on intensity of vibration or controlling an eccentric vibration motor (16) to rotate in a low frequency.
