MEMS Microphones for consumer

Hearing is the most differentiated of all the senses. Our ears distinguish between up to 400,000 sounds, ten octaves and 7,000 different tone pitches. Inspired by the human senses - our XENSIV™ MEMS microphones give »smart ears« to audio and voice-controlled devices. Making communication more natural and intuitive.

Our XENSIV™ MEMS microphones introduce a new performance class of digital MEMS microphones that overcomes existing audio chain limitations. Infineon’s microphones provide premium digital audio raw data, perfect to combine with advanced audio signal processing algorithms for best noise attenuation experience in any environment.

Immerse yourself in a virtual sound stage! A human auditory system is simulated by placing two Infineon high performance MEMS microphones in the ears of an artificial head. These are connected to an Infineon Audiohub Nano board that sends the recorded sound directly to your headphone. Because of the low self-noise of the microphones, it feels like you are listening with your own ears and are right were the action is!

What is the difference between a high and a low performance MEMS microphone? Hear for yourself! In this demonstrator, we focus on a microphone’s dynamic range, which describes how well microphones can record quiet as well as very loud sounds. The upper limit of a microphone’s dynamic range is defined as the Acoustic Overload Point (AOP) - the maximum volume a signal can have before the physical limits of the microphone are reached. The lower limit is defined by the microphone’s self-noise level, or Signal to Noise ratio (SNR). A microphone can only record sounds above its self-noise level. Here, you will get to hear how recordings sound differently based on whether you use a low or a high dynamic range microphone.

Elliptic Labs demonstrates with the MS Surface Pro X how our XENSIV™ MEMS microphones can be used to automatically lock the laptop screen when the user walks away from the laptop, simplifying laptop security features that make your data safe. Watch Laila Danielsen, the CEO of Elliptic Labs, explaining the joint solution and its benefits.

Always on and ultra-low power voice pick-up on the edge. Cristal clear voice commands delivered to the edge of your application, picked up with ultra-low power consumption! Infineon´s best in class XENSIV™ MEMS microphones are redefining the standards for voice-user-interfaces in challenging situations. Exact voice-pick-up from long-distance, with a whispered voice or even in noisy environments is a challenge for smart assistants. When combined with Syntiant’s programmable Neural Decision Processors (NDPs) and their development platform NDP101B0, applications can be supported for audio and keyword classifications, on- and offline. This enables developers to create custom, always-on voice user interfaces, optimized for battery-powered devices.

In this video, Rafael Hostettler, General Manager of Roboy, explains how Infineon and Roboy are creating the next generation of humanoid robots with equivalent sensory capabilities as humans. Roboy is a research organization in close collaboration with the Technical University of Munich, which tries to push the boundaries of innovation and to use technology in new, unexplored ways to develop the first humanoid robot. Infineon provides its latest state of the art products from the XENSIV™ product family. In the current version of ROBOY 2.0, three major products of Infineon are integrated: 60GHz radar MMIC (for material detection), MEMS microphone (for voice/speech detection) and 3D magnetic sensors (for natural movements of the body parts). The sensors give Roboy its humanity – he can see, hear, feel and understand what is happening around him.

Moshe Sheier, VP Marketing at CEVA, a leader in licensing signal processing platforms and AI processors, presents the CEVA ClearVox and WhisPro reference design for voice-user-interface (VUI) applications, enabled by Infineon digital MEMS technology. This reference platform is ideal for far-field speech recognition in devices, such as smart speakers, voice-enabled IoT, and home automation appliances. In addition, the 17 built in Infineon XENSIV™ MEMS microphones on CEVA’s ultra-low-power DSP-based platform allow engineers to select and define the position/location of the microphones in their final voice-user-interface application.

Tomasz Zernicki, Co-Founder and CTO of Zylia, a leader in the field of 3D audio recording and production, speaks about the first-ever portable recording studio, the Zylia ZM-1. Equipped with 19 Infineon XENSIV™ MEMS microphones and a special software developed by Zylia, the solution can break down and isolate the different sound tracks in real-time, providing a truly unique music experience with high-quality sound.

Our premium partner XMOS is a provider of voice and audio processing and control ICs. In this video, Gwen Edwards, Product Marketing Director at XMOS, talks about the company’s collaboration with Infineon to advance the future of human machine interfaces (HMI) and demonstrates the capabilities of the VocalFusion strereo development kit for Amazon AVS, powered by 4 configurable Infineon IM69D130 XENSIV™ MEMS microphones.
