Better Microspeakers Utilizing Hiperco Alloys
This Voice Coil Spotlight article by Aminul Md Mehedi (Senior Application Development Engineer at Carpenter Technology Corp.) explains how the Carpenter-developed high-performance Hiperco 50 and Hiperco 27 soft magnetic alloys can contribute to better performing microspeakers and earphone drivers, improving "decibel (dB) density" in miniaturized consumer electronic devices. This article was originally published in Voice Coil, November 2020.
The Capacitance Multiplier
In this article for audioXpress, Bill Reeve helps us to make sense of a misunderstood circuit. A capacitance multiplier is useful as a power supply low-pass filter. It is commonly said that, like Miller capacitance, the capacitor’s value in this circuit is “multiplied” by the transistor gain (β) to lower the filter’s pole frequency. The transistor-enhanced filter does that and more, as the article explains in detail. This article, an excellent tutorial on analog circuit design, was originally published in audioXpress, August 2012.
Bold North Audio Expands Range with New Carbon Fiber Cone Woofers
American audio solutions manufacturer MISCO announced the introduction of the BWF-6503, a 6.5" red carbon fiber woofer, and the BMW-4001, a 4" carbon fiber midwoofer to its growing line of premium and performance-based drivers.

AMS Launches Smallest Proximity Sensor To Enable Integration of New Functionality In Space-Constrained Wireless Earbuds
AMS launched the TMD2636, a fully integrated proximity sensor which occupies 30% less space than currently available solutions, and delivers transformational added value to manufacturers of True Wireless Stereo (TWS) earbuds. The new TMD2636 fully integrated proximity sensor module is supplied in an ultra-low-profile package. This means that an earbud can now accommodate multiple proximity sensors to increase reliability or add new features and still save power when the earbud is not in use.
Focal Unveils Clear MG Professional Open-Back Headphones
