New Speaker, Headphone, and Earphone Perspectives with Voice Coil January 2022

We're off to a great start in 2022. Starting with details about the promise of Iron Nitride (FeN) magnets, followed by an article about Liquid Injection Molding Silicon for Next-Generation Headphone Surrounds. Next up, James Croft reviews a surround speaker patent granted to Klipsch, and Vance Dickason characterizes the Satori MW13TX-4 TPCD-cone woofer from SB Acoustics and the high-power WF275BD01 10.75" woofer from Wavecor. All articles now available to read online, PDF and print.

Looking forward to serving the loudspeaker industry for another year, Voice Coil starts strong with a focus on Headphone OEM Devices and Parts, and a Spotlight article on speaker design, written by Brian Cho, the CEO of Resonado Labs. In his first Acoustic Patents column for 2021, James Croft writes about a signal processing system, allowing users to control a lower frequency acoustic range of a loudspeaker system, and Vance Dickason kicks off his Test Bench characterizations with the new Bold North Audio BWX-6502 Midbass, and the Wavecor TW022WA09 22mm textile dome tweeter.

The high-end headphone market continues to grow as the generic headphone product category expands globally. With wireless now sending mainstream consumers in completely new directions for personal audio, there is still room for brands to grab a share of the market in the wired, premium segment. The new PM-50 Planar Magnetic headphones are a way for Andover Audio to enter the space, proposing a relatively affordable ($500) design that still manages to surprise with walnut housings and replaceable ear-cushions.

For the January 2019 edition of Voice Coil magazine, Mike Klasco and Nora Wong have compiled a special Focus article on New Materials for Earphones and Headphones. For those looking to differentiate their new products, the two Menlo Scientific consultants provide a unique and valuable perspective on multiple possibilities and designs for drivers, materials for assemblies and enclosures, choices for headbands and ear cushions, signal processing, and even cables.

Voice Coil January 2019 is now available. This edition focuses on New Materials for Earphones and Headphones and also includes a valuable listing of Earphone and Headphone Manufacturers and a schedule of headphone-centric events for the year. In Acoustic Patents, James Croft looks at a new patent of a multilayer voice coil plate and flat speaker based on the same, while in this month's Test Bench Vance Dickason features a 1" compression driver from Radian Audio Engineering, and a 1" soft dome tweeter from Eminence.
