最新消息

High-frequency response above 8 kHz is critical to sound clarity and stereo imaging in headphones, yet most drivers struggle to reproduce it cleanly. Our latest white paper examines why peaks and valleys appear in this frequency range and what it takes to eliminate them.

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.
