MEMS Microphone
For many years the MEMS microphone market has been dominated by a few major vendors, Knowles and Infineon (plus many companies using Infineon die, including AAC). Few new companies have emerged with new technologies that could possibly upset the status quo. Vesper was one such company, but it only had minimal success before it was […]
