Material optimization Smaller, Lighter, and Decibel Dense Microspeakers for Consumer Electronics Using Advanced Magnetic Alloys

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.

Ordered Growth in Hiperco® 50 Alloys

Increasing demand for tighter tolerance laminations to meet challenging design criteria led to the investigation of a net dimensional changes in Hiperco 50 alloys (49Fe-49Co-2V) after post-fabrication annealing. This white paper evaluates the root cause and explores a special process designed to improve the dimensional change characteristics of Hiperco 50 alloys.
