Why Smart Speakers Need This Driver?

Challenges with Conventional Drivers

Low Sensitivity = Poor Voice Recognition

Typical 80-85dB drivers need higher power amplification, causing voice wake-up delay.

Limited Cavity Space = Hard to Fit

Smart speakers are compact; traditional external magnet designs are too tall for height-restricted cavities.

Voice and Music Cannot Both Excel

Insufficient frequency ceiling or high distortion causes robotic voice and thin, lifeless music playback.

High Power Draw = Shorter Battery Life

Low-sensitivity drivers drain more power, shortening portable smart speaker runtime significantly.

XDEC 50mm Multimedia Speaker Solution

95dB Ultra-High Sensitivity = Crystal-Clear Voice

Achieves 95dB at just 0.1W input. Fast wake-up response, high recognition accuracy, works well with small amplifiers.

Compact 50mm x 11mm Internal Magnet = Easy Cavity Fit

Internal magnet structure only 11mm total height; round design fits standard smart speaker round cavities, no custom bracket needed.

F0~19KHz Wide Response = Optimized for Voice + Music

F0 at 480-720Hz with 19KHz ceiling, distortion under 5%, delivering clear speech and layered musical playback.

2W Low Power Design = Extended Battery Life

2W/3W power spec perfectly matches portable smart speaker power budgets for efficient voice wake operation.
