Title:
VIBRATION GENERATOR
Document Type and Number:
WIPO Patent Application WO/2013/190744
Kind Code:
A1
Abstract:
Provided is a vibration generator having a vibration-generating element and a housing part. The vibration-generating element is provided with a cantilever part, a weight part provided on the free-end side of the cantilever part, and a piezoelectric-conversion part for generating electricity using the swinging of the cantilever part. The housing part constitutes at least part of a through-hole through which liquid can pass, and causes the direction from the free-end side to the fixed-end side of the cantilever part to correspond to the direction of the through-hole to allow the cantilever part to be accommodated in the through-hole. The distal end of the weight part projecting from the cantilever part constitutes a curved surface in at least the direction linking the free-end side and the fixed-end side of the cantilever part.
