STMicroelectronics Expands MEMS Microphones with Next-Generation Micro-Machined Acoustic Devices

The innovative MEMS microphones that use sensor technology from OMRON will significantly raise the bar in sound quality, reliability, and cost-effectiveness for existing and emerging audio applications like cell phones, wireless devices and games that respond to voice inputs, across a range of market segments. MEMS microphones have recently emerged to compete with the traditional electret condenser microphones (ECM). Leveraging established high-volume silicon manufacturing processes, micro-machined acoustic devices meet price points set by electret microphones, while boasting superior reliability and robustness. Importantly, MEMS microphones can be made smaller than the most compact ECMs and are less susceptible to mechanical vibration, temperature variations and electromagnetic interference, which is important in cell phones and other devices with an audio input, such as notebook computers, video recorders, digital cameras, as well as hearing aids or electronic stethoscopes…
