The piezoelectric micro speaker includes a substrate having a cavity formed therein and a diaphragm that is disposed on the substrate that overlaps the cavity. A plurality of first vibrating membranes having concentric annular ring shapes are disposed in a first region of the diaphragm corresponding to a center of the cavity. A second vibrating membrane including a different material from that of the first vibrating membranes is formed in the second region of the diaphragm corresponding to an edge of the cavity. A piezoelectric actuator for vibrating the first vibrating membranes is formed on and between the concentric annular rings of the first vibrating membranes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Piezoelectric micro speaker including annular ring-shaped vibrating membranes and method of manufacturing the piezoelectric micro speaker","description":"A piezoelectric micro speaker and a method of manufacturing the same are provided.
