piezoelectric vibrator |
| abstract |
An object of the present invention is to provide a piezoelectric vibrating body capable of emitting sound waves efficiently and instantaneously expressing vibration called a tactile sensation when a voltage is applied. The present invention is a piezoelectric vibrator comprising a piezoelectric laminate in which alignment film layers made of polylactic acid and conductive layers are alternately stacked, and grippers for holding both ends thereof, adjacent to each other via the alignment film layer. One of the conductive layers is short-circuited to the negative electrode, and the other is short-circuited to the positive electrode. The orientation film layers sandwiched by each conductive layer are stacked in such a way that the expansion and contraction direction is the same direction when the current flows. (ii) The piezoelectric laminate has the same orientation Two parallel surfaces whose plane direction is parallel to the film layer, and two end surfaces A and B sandwiched by these parallel surfaces and parallel to each other, (iii) the two ends of the holding include the end surface A and the end surface B respectively, and , applying stress to the piezoelectric laminate between the end faces A and B through the holding tool. |
