Unique Speakers, Parts, and Concepts in Voice Coil September 2022 

Voice Coil September 2022 offers an article about solutions for Smart Speakers and Voice Processing by Mike Klasco, and an updated directory of Magnet Vendors and Distributors for 2022. James Croft reviews a recent patent awarded to Tymphany for a new Coaxial Loudspeaker design, and Vance Dickason characterizes two very original drivers in Test Bench. The HF1460 compression driver from Faital Pro and the Tang band the W4-2356 4" full-range woofer with an off-centered voice coil.

In Voice Coil September 2021, Vance Dickason writes about DSP crossovers from Danville Signal, Joe Hayes (Vastigo) writes about the DaS AuReality patented 3D loudspeaker technology, and Mike Klasco finds speaker-related technologies that help support smart speaker design efforts. This edition's Test Bench characterizes three new 25mm high-frequency tweeters from BlieSMa, using silk, beryllium, and diamond domes: BlieSMa’s T25S-6, T25B-6, and T25D-6.

At the end of July 2020, audioXpress ran a product release on Vesper's VM3011 intelligent digital micro-electro-mechanical systems (MEMS) microphone. Its claim to fame is a power saving architecture that enables battery standby life that otherwise would be unattainable without the "smarts." There are another half-dozen developers working on integrating all sorts of capabilities within the MEMS mic package. This article, originally published in The Audio Voice newsletter, discusses those developments.

Syntiant, a California-based AI chip company focused on moving machine learning from the cloud to edge devices, announced a partnership with Infineon Technologies, to service the rising demand for voice user interface (VUI) in electronic devices. Optimized for battery-powered devices from true wireless earbuds to mobile phones to smart speakers, Syntiant’s partnership with Infineon enables more efficient voice control and custom command detection to numerous product configurations.
