Abstract:
Provided are a piezoelectric acoustic transducer and a method of fabricating the same. In the piezoelectric acoustic transducer, a piezoelectric portion is formed in a portion of a diaphragm, and a deformation layer is formed in another portion of the diaphragm. Deformation of the piezoelectric portion is transferred to the deformation layer, or deformation of the deformation layer is transferred to the piezoelectric layer so that the deformation layer vibrates with the piezoelectric layer.
