Title:
PIEZOELECTRIC VIBRATION GENERATING DEVICE AND INSTRUMENT PROVIDED WITH PIEZOELECTRIC VIBRATION GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/016630
Kind Code:
A1
Abstract:
Provided are: a piezoelectric vibration generating device that is finished with less manufacturing time and has a longer lifespan than the prior art, and that uses a circular vibrating plate and piezoelectric vibrating element; and an instrument provided with said piezoelectric vibration generating device. A vibrating shaft 17 is configured from a metal screw member arranged so as to pass through a third through-hole 4 provided to a vibrating plate 3, a second through-hole 13 of a piezoelectric vibrating element 15, and a first through-hole 5 of a first case half-section 7, so that a head part 17C is positioned on a side near a second case half-section 9 and a screw part 17D at the distal end extends out to the exterior of the first case half-section 7. A metal nut member 19 is fitted with the screw part 17D.
