More Information
Summary:A piezoelectric vibration module includes a vibration plate adapted to have one end fixed and the other end not fixed and driven in a vertical direction based on the fixed first end, a first piezoelectric element attached to the top or bottom of the vibration plate and adapted to generate a vibration power when power is applied, and a weight formed in the other end of the top or bottom of the vibration plate and adapted to control the vibration frequency of the piezoelectric vibration module. The first piezoelectric element is attached to the top or bottom of the vibration plate with a predetermined interval from a fixed point at the one end of the vibration plate.
