"But there's one glaring issue with smart glasses today: bulkiness. Also: I tested Meta Ray-Ban Display alternatives, and these are better in several ways for less money Various components in smart glasses, from camera sensors to batteries to speakers, demand real estate that goes beyond traditional eyewear sizes. In turn, the added bulk can make the worn experience a burden and inadvertently compromise the room needed for cooling systems, preventing them from running at an optimal level."
"Mike Housholder, VP of Marketing at xMEMS Labs, tells me there's a sweet spot when it comes to the weight of smart glasses: 30 grams. For reference, the Meta Ray-Bans weigh around 50 grams. So how do you slim things down without sacrificing performance? xMEMS is pitching a micro loudspeaker, codenamed Sycamore. According to Housholder, it's 70% smaller and 90% lighter than traditional coil speakers, and the reduction in real estate was evident the moment I picked up a pair of proto"
Smart glasses remain bulkier than traditional eyewear, compromising comfort and internal cooling. Various components such as camera sensors, batteries, and speakers occupy significant real estate inside frames. Added bulk can limit space for cooling systems and cause thermal performance issues. xMEMS Labs developed solid-state audio and thermal solutions for headphones, earbuds, and smart glasses. The Sycamore micro loudspeaker is 70% smaller and 90% lighter than traditional coil speakers, freeing internal space. A micro cooling fan-on-chip actively manages heat to prevent performance throttling. A target weight of about 30 grams is identified for comfortable smart glasses, versus about 50 grams for Meta Ray-Bans.
