xMEMS Announces Mass Production of Cypress Full-Range PiezoMEMS Ultrasonic Transducer

xMEMS Labs announced that its Cypress full-range MEMS “sound-from-ultrasound” microspeaker, together with the Alta-S companion drive ASIC, is now ready for mass production. This represents the industry’s first commercially viable full-range solid-state audio solution capable of meeting the demanding Sound Pressure Level (SPL) requirements for noise-cancelling true wireless stereo (TWS) earbuds. It also indicates that xMEMS is fully convinced that the device will be deemed safe to humans and for extended usage inside the ears.

To be unveiled at CES 2025 is a new example of a MEMS microspeaker company that now offers an integration with a MEMS microphone. SonicEdge, the startup that pioneered ultrasound MEMS drivers and has yet to enter the market, will present SonicTwin, an integrated speaker-microphone in a single package. Combining the company's patented modulated ultrasound technology that eliminates traditional mechanical vibrations, makes the integration with a microphone and sensors much easier with potential benefits also for ANC and lower-power in TWS earbuds and headphones.
