xMEMS Introduces Amplifier-Less MEMS Tweeter for 2-Way Wireless Earbuds

xMEMS unveiled Lassen, the company’s latest member of its growing µFidelity range of MEMS drivers, and the first “amplifier-less” MEMS tweeter optimized for 2-way True Wireless Stereo (TWS) earbuds. According to xMEMS, Lassen brings a number of advantages with no need for a piezo amplifier, reducing cost, size, and power consumption while maintaining exceptional sound performance with up to 115dB SPL in the 6kHz–20kHz range. For manufacturers, Lassen lowers integration costs by 25% making room for other advanced features, and allowing consistent sound quality in mass production.

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.
