Due to its versatile mechanical and electrical properties, silicon has taken over the microelectronic and micromechanical worlds. Thanks to CMOS (Complementary Metal Oxide Semiconductor) and MEMS (Micro ElectroMechanical Systems) technologies yielded by this material, electronic devices can interact with our surroundings. This combination has created product categories such as smartphones and wearables, which would have belonged to science-fiction thirty years ago.
Originally patented in 1877, the electrodynamic speaker is a holdover from the 19th century still surviving in our 21st-century products. As one of the only two smartphone functions not having transitioned to solid-state technology, it is responsible for the lacklustre audio performance ubiquitously decried by users. USound has developed its MEMS products such as Ganymede to address that issue and bring a superior audio experience to the mobile world. The technology developed by USound will influence the acoustic market just as LED has influenced the optical sector.
