Electro-Mechanical Frequency Response of a Piezo-MEMS Speaker Measured by Laser Diode Feedback Interferometry

Journal of microelectromechanical systems
Piezo-MEMS speakers based on the inverse piezoelectric effect are becoming increasingly attractive thanks to their low power consumption and are good candidates for miniaturized devices for in-ear audio systems.

Unveiling vibration features of a smartphone piezo-actuated audio-screen with feedback interferometry

Frontiers in Optics + Laser Science 2025 (FiO, LS)
For preliminary investigations of vibration modes of a smartphone screen, turned into a next-gen loudspeaker by electrically driven piezoceramic transducers attached to it, we exploited semiconductor laser feedback interferometry.
