This paper reports piezoelectric aluminum nitride (AlN) based microelectromechanical systems (MEMS) speakers. We introduce a novel geometry of microspeakers based on AlN to meet the requirements of modern applications such as phones, tablets, laptops, and in ear applications. We introduce the principle, design, and characterization results. The speakers were fabricated on cavity silicon on insulat...
