Collaborate Disseminate
Here’s a warning we never thought we’d have to give: when you’re in an audio or video call on your phone, avoid the temptation to doomscroll or use an app …read more Continue reading Your Noisy Fingerprints Vulnerable to New Side-Channel Attack
If you’ve ever wondered what lies beneath the barely visible hole in the can of a MEMS microphone, you’re in luck, because [Zach Tong] has a $10 pair of earbuds …read more Continue reading Up Close and Personal with a MEMS Microphone
Conventional speakers work by moving air around to create sound, but tiny speakers that use ultrasonic frequencies to create pressure and generate sound opens some new doors, especially in terms …read more Continue reading Tiny Speaker Busts Past Sound Limits with Ultrasound
These days it’s hard to not come across solid-state (micro-electromechanical systems, MEMS) microphones, as they are now displacing electret microphones almost everywhere due to their small size and low cost. …read more Continue reading After MEMS Microphones, MEMS Speakers Enter The Market
Earlier this year, we introduced solid-state micro-speaker technology from California’s xMEMS Labs that’s designed to replace coil-based drivers in wearable audio products. Creative was then announced as the first manufacturer to include the technology… Continue reading Solid-state micro-speakers bring the low end to ANC earbuds
xMEMS Labs out of Santa Clara, California, is aiming to replace century-old coil-based speaker technology with silicon-based microspeakers, and has launched three Solid-State Fidelity solutions for use in upcoming true-wireless earphones, in-ear monito… Continue reading xMEMS aims for mobile audiophiles with silicon-based microspeakers
There is a bit of a paradox when it comes to miniaturization. When electronics replaced mechanical devices, it was often the case that the electronic version was smaller. When transistors …read more Continue reading MEMS Teardown and Macroscopic Models
The quality of any measurement can only be as good as the instrument used to gather it, and for acoustic measurements, finding a good enough instrument can be surprisingly difficult. …read more Continue reading A Lab-Grade Measurement Microphone For Not a Lot
What does it take to make your own integrated circuits at home? It’s a question that relatively few intrepid hackers have tried to answer, and the answer is usually something …read more Continue reading Old Printer Becomes Direct Laser Lithography Machine
Although today’s earbuds may seem fairly small, they’re limited in form and function by the fact that their speakers require membranes and magnets. A new prototype microspeaker overcomes those limitations, potentially providing more uses for in-ear hea… Continue reading NED microspeaker tech may open up new uses for earbuds
