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.

Luxshare-ICT, one of the largest manufacturers and supplier for global consumer electronics brands, and Austrian MEMS pioneer USound have developed Gemini, an innovative hybrid audio module that offers numerous advantages through its 2-way audio technology combining a MEMS and a dynamic driver coaxially aligned. The solution not only enhances sound quality but allows effective active noise cancellation (ANC) applications with MEMS drivers.

xMEMS Labs and Bujeon Electronics have partnered to create a family of 2-way speaker modules to accelerate design of next generation high-resolution and lossless audio-capable TWS earbuds. The solution integrates a high-performance 9mm dynamic driver custom-designed by Bujeon with an xMEMS' Cowell tweeter, the world’s smallest monolithic MEMS microspeaker at just 22mm. The reference design combines an xMEMS Aptos MEMS speaker amplifier to create a "drop-in" solution compatible with today’s leading TWS system-on-chips.

As a much touted unofficial closing event for CES, Samsung Electronics introduced its latest line of Galaxy smartphones. As the annual tradition mandates, apart from smartphones of multiple sizes, some of which come with a stylus, Samsung also introduced accessories for those phones. In this case, an updated set of True Wireless Earbuds with improved sound quality and intelligent ANC, available in multiple colors, including purple. As a differentiator, the Buds Pro use a two-way driver design.
