Webinar: Smaller, Lighter, and Decibel-Dense Microspeakers

Steady progress in the miniaturization of electronics combined with increasing demand for multimedia technology requires smaller micro speakers with higher audio output. The goal of improving “decibel (dB) density” adds additional functionalities in consumer electronic devices, but one of the key constraints in miniaturization is the magnetic circuit of the device. Carpenter Technology developed and studied design with high-performance alloys and found an enhancement in performance with reduced device size and better system level benefits.

In this webinar, we share our findings and provide insights into making a power and dB dense smaller and lighter magnetic assembly for microspeakers.
