    摘要: Provided are a piezoelectric micro-acoustic transducer and a method of fabricating the same. In the piezoelectric micro-acoustic transducer, a diaphragm is divided into a first region and a second region. The first region may be formed of a material capable of maximizing the exciting force, and the second region may be formed of a material having less initial stress and a lower Young's modulus than the first region. Also, the second region has a corrugated shape.
