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.

The new Cypress MEMS speaker from xMEMS Labs achieves 40X louder bass response on a single monolithic, miniaturized device, achieving well above the 130dB SPL at low frequencies, required for ANC implementations on TWS earbuds. The new xMEMS Cypress achieves this groundbreaking performance by using ultrasound technology. The new development will be demonstrated at CES 2024 by appointment only, with mass production scheduled for late-2024.
