ABSTRACT:
A piezoelectric vibrating plate covered by a conductive layer at a vibrating distal end of the vibrating plate and at an obverse face. Slits cut in the conductive layer separate piezoelectric vibrators in a first area of the vibrating plate from non-vibrating dummy vibrators in a second area of the vibrating plate.
