- THD Podcast 63 - xMEMS Disrupting the $10B Speaker Market with Worlds First True MEMS Piezo Speakers
The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market.
In episode 63, Michael Ricci, Director of Electroacoustic Engineering at xMEMS, joins us to tell us all about the world's first truly piezo MEMS speaker. The xMEMS team of audio and piezo MEMS semiconductor experts are disrupting the $10B speaker market with the first True MEMS speakers. xMEMS addresses in-ear personal audio devices delivering a new combination of audio fidelity, size, energy consumption and uniformity not possible with traditional voice coil or hybrid MEMS approaches.Until now, the industry has relied on antiquated, centuries-old multi-component voice coil speakers requiring labor-intensive, high variability factory assembly lines. xMEMS leverages semiconductor precision and manufacturing scalability. Micron-level precision and scalability of semiconductor process permits Speaker-to-speaker uniformity and repeatability. The Piezo MEMS drive creates speakers with faster mechanical response than possible with legacy technologies. We are bringing a new era in sound by replacing decades old, manually-assembled, highly-variable voice-coil speaker technology including dynamic drivers and balanced armature drivers, with a high-precision, high consistency, monolithic semiconductor process.Please like, subscribe, share, and comment with your feedback!

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market.
In episode 62, Mickael Bouffaut and Rick Modina join the podcast to introduce their engineering and mass production facility. We think this is what people need to see in terms of how products are built. There is a massive gap between the shelf and the mind in what it takes to make a product. Kaertech focuses on advanced med-tech type products and we felt this was the perfect factory to give our viewers a factory tour.Please like, subscribe, share, and comment with your feedback!

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market.
In episode 61, Dr. Finnur Pind, CEO of Treble Technologies, joins to tell us about their cutting-edge sound simulation technology and processes. They are bringing this next generation technology to market with the vision of enabling designers of the built environment to create a better sounding world. The technology revolves around using sound simulation and rendering software to model acoustic behaviour in buildings, structures, or other enclosures such as cars. There are also applications in VR and gaming that hold great promise.The research work which serves as the basis of Treble was done at the Technical University of Denmark (DTU), in close collaboration with Ecole Polytechnique Federale de Lausanne (EPFL) and Virgina Tech. This work was led by leading scientists in the field of acoustics and scientific computing, most of whom are closely involved in Treble Technologies today. The company is based in the city center of Reykjavík, Iceland.Please like, subscribe, share, and comment with your feedback!

An exciting new company that lists Mark Cuban as one of the main investors.Link for Whitepaper: https://docsend.com/view/ssbfntufdqzda6qnQuestion in the episode:Simon asked, “So you’ve got your ANC earbuds, then you steal off one of the microphone audio streams, process that then you get an output signal in what format? I2S that you mix back into the BT Chip?”Answer: Yes, the external ANC mic, also often known as the 'feed-forward' mic, in contrast to the internal canal mic that is feed-back mic is where the external content comes from for the Chatable processing.Please like, subscribe, share, and comment with your feedback!
