Abstract
Official abstract text for this publication.
There is provided a piezoelectric vibration actuator including: a flat cover member; a vibration portion including a vibration plate that is spaced apart from the cover member in parallel by a predetermined distance and a piezoelectric element that generates a vibration force by repeatedly expanding and contracting according to power applied from the outside; a weight portion disposed on the vibration portion to increase the vibration force of the piezoelectric element; and a binding member fixing the vibration portion and the weight portion. In addition, an enclosure portion is interposed between the weight portion and the vibration portion to enclose the center areas of the vibration portion, thereby making it possible to protect the piezoelectric element.
