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.

November signals another anniversary for Voice Coil, the leading periodical for the loudspeaker industry. In this edition, Md Mehedi writes about how new Hiperco alloys can contribute to improved microspeakers, Mike Klasco discusses "This Year’s Crop of Measurement Microphones," followed by a directory on the topic.

Voice Coil April 2019 featured another great Focus article by Mike Klasco (Menlo Scientific) discussing trends in Microspeakers. With more than 1.6 billion mobile phones built annually, each with a microspeaker for the speakerphone and another for the receiver, this side of the speaker industry attracts the giants. Get the full scoop on one of the hottest market segments.

This key event for the audio industry is the ALMA International Symposium & Expo (AISE), promoted by the Association of Loudspeaker Manufacturing & Acoustics (ALMA) International. The two-day event traditionally happened just before CES. Now, the industry gathering is going to become less of a secret, since this year's AISE is expanding and moving to June 9–10, 2019, just prior to and in affiliation with InfoComm in Orlando, FL. It’s important for everyone to learn more about AISE 2019 and why they need to be there.
