High-End Loudspeakers for Smartphones & Small Appliances
What is a MEMS-based loudspeaker?
The best sound quality still comes from bulky high-end loudspeakers. CEA-Leti is going a step further into making loudspeakers compatible with micro-fabrication processes with a new piezoelectric micro-loudspeaker using almost exclusively silicon. CEA-Leti small loudspeaker achieves similar performance as larger loudspeakers using conventional manufacturing techniques. It is fitted into a 3D printed horn that mechanically improves performances.
CEA-Leti researchers will tune this loudspeaker using a system approach to
improve performances and make sure it fits well into current applications, such
as smartphones and other IoT devices. Additional digital signal processing,
acoustical tuning and packaging techniques will be investigated.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
