Document Type and Number:
WIPO Patent Application WO/2016/200094
Kind Code:
A1
Abstract:
The present invention relates to a piezoelectric vibration module comprising: a vibration plate, the first end of which is fixed, the second end of which is not fixed, and which is driven in the vertical direction with reference to the fixed first end; a first piezoelectric element attached to the upper or lower surface of the vibration plate so as to generate a vibration force in response to application of power; and a counterweight formed on the upper surface of the vibration plate or on a different end of a different surface thereof so as to adjust the vibration frequency of a piezoelectric vibration module, wherein the first piezoelectric element is attached to the upper or lower surface of the vibration plate at a predetermined interval from a fixed point on the first end of the vibration plate.
