In micro speakers and earphone drivers, the voice coil is the heart of the motor. Its job is straightforward: convert electrical current into mechanical force. But getting that conversion right both efficiently and reliably at miniature scale, is anything but.

As switching power supplies become ubiquitous in modern electronics – from EV chargers to consumer appliances and communication hardware, managing Electromagnetic Interference (EMI) has never been more critical.

This White paper examines how COMSOL simulations can be used to optimize the acoustic design of smart glasses, where sound is radiated in near-field or free-field conditions.
