<p>PURPOSE: A tactility presentation device is provided to increase a driving displacement transmission amount by enabling a driving displacement transferring bar having the piezoelectric body to have a driving displacement about a curving transformation of the piezoelectric body. CONSTITUTION: A ring shaped elastic plate(110) has opening inside. Piezoelectric bodies(120a,120b) are included in the top and the lower part of the elastic plate. According to sanction voltage the piezoelectric body generates driving displacement. One side of the driving displacement transfer bar(130) is fixed on the top of the piezoelectric body. Another side of the driving displacement transfer bar is expanded towards the opening. The piezoelectric body has the same shape and size with the elastic plate'.</p> |
