Title:
振動ユニットおよびその駆動方法
Document Type and Number:
Japanese Patent JP7331549
Kind Code:
B2
Abstract:
To provide a vibration unit in which the amount of information transmitted when responding is increased, and a driving method thereof.SOLUTION: In a vibration unit 1, when a plurality of piezoelectric vibrators 20 are presses in order, a control unit 50 transmits a driving signal to the piezoelectric vibrators 20 pressed later. At this time, the control unit 50 transmits the different driving signals to the piezoelectric vibrators 20 for each pressing order to vibrate the piezoelectric vibrators 20. Therefor, the vibration unit 1 can give different responses to a user according to the pressing order of the piezoelectric vibrators 20, and can give various information according to the types of responses.SELECTED DRAWING: Figure 8
