Latest news

TWS earphones pack an extraordinary amount of technology into a very small space: Bluetooth, ANC, microphones, a battery etc. Getting the acoustics right in that environment is a serious engineering challenge.
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.
