A piezoelectric blade protection structure for a plurality of juxtaposed piezoelectric blades mounting onto a circuit board to provide protection and anchoring effect for the piezoelectric blades. A protection member is mounted onto the vibration nodes of the piezoelectric blades to prevent the piezoelectric blades from broken by improper impact of external forces. The protection member, piezoelectric blades and circuit board are interposed respectively by a upper elastic element and a lower elastic element to provide a desired vibration space and anchoring for the piezoelectric blades.
