A new MEMS tweeter for wireless earbuds doesn't require an amplifier
xMEMS is making is easier for companies to use micro speakers to improve earbud audio quality.
MEMS solid-state drivers have provided a big sound boost to wireless earbuds recently, offering the ability for companies to pack in a hybrid setup for a wider, more immersive soundstage. xMEMS' silicon-based micro speakers have been a popular choice for this purpose, with the company's Cowell and Muir drivers already appearing in products from Creative Labs and others. Since it doesn't require a separate piezo amplifier chip like Cowell and Muir, it's more cost effective to integrate with savings of up to 25 percent compared to the other MEMS drivers.
