| contents | Microelectromechanical systems (MEMS) speakers are compact, scalable alternatives to traditional voice coil speakers, promising improved sound quality through precise semiconductor manufacturing. This review provides an overview of the research landscape, including ultrasound pulse-based and thermoacoustic sound generation, classifying MEMS speakers by actuation principle: electrodynamic, piezoelectric, and electrostatic. A comparative analysis of performance indicators from 1990-2025 highlights the dominance of piezoelectric MEMS with direct air displacement, focusing on miniaturization and efficiency. The review outlines upcoming research challenges and identifies potential candidates for achieving full-spectrum audio performance. A focus on innovative approaches could lead to wideband adoption of MEMS-only speakers. |
