In the world of speakers, mass is the enemy of high frequency response. In order to get the crispest highs, some audiophiles swear by speakers in which the moving element …read more Continue reading A Hi-Fi Speaker from some Foil and Magnets
The new, second-generation Google Nest Hub is here, with one big change from its 2018 predecessor: it can track your sleeping patterns from a bedside table, with no wires or wearables required, besides offering all the smarts of Google Assistant.Contin… Continue reading The new Google Nest Hub tracks your sleep from the side of your bed
Scientists at the University of Washington (UW) have leveraged modern machine learning technology to produce a prototype smart speaker that can monitor a person’s heart, without the need for them to physical touch it. The contactless method of tracking… Continue reading Smart speaker uses AI to detect irregular heart rhythms in the room

Back in 2014, French audio house Devialet launched a $2,000, 750-W wireless speaker that looked like nothing else out there, with the drivers at the side pulsing in and out of the unit’s curvy body to generate its enormous distortion-hating sound.Conti… Continue reading Devialet updates its extraordinary Phantom wireless speaker for 2021
Scientists at Germany’s Chemnitz University of Technology have spent years developing compact and discreet speakers that are quite literally paper thin, and the latest breakthrough improves on this technology for a more immersive experience. The scient… Continue reading Printed paper speakers roll into a ring to offer surround sound
Distributed-mode loudspeakers work rather differently from the typical drivers used in 99% of applications. Instead of using piston-like motion to create sound waves, they instead rely on exciting an entire panel to vibrate and thus produce sound. [JGJMatt] decided to build a pair of bookshelf-sized units, with great results.
The …read more

Speaker design used to be as much about woodwork as it was about advanced acoustic mathematics. In recent decades, technologies such as digital signal processing and 3D printing have changed the game significantly. Leaning heavily on these techniques, [ssashton] developed a design called Mr. Speaker.
The speaker contains a 3″ …read more
