Beryllium Coated Advantages in mass Production of Speakers
This technology is a technique to make speaker diaphragm implanted into Beryllium coated molds (the voice coil can be added in the future).
1.High consistency
Beryllium mold accuracy is much higher than that of hand-fitted cone and surround.
2.Stable quality
Production precision is achieved by machine and mold, replacing manual glue and assembly, so the quality of batches is stable.
3. Widely applied automation
Parts can be implanted and removed in an automated manner, reducing manual use.
4.Competitive cost
Higher than traditional process yields and labor-saving production can provide competitive prices.

What Benefit of Beryllium Technology for Speaker Building.
Beryllium material is the hardest, lightest and fastest transducer material in the existing headphone diaphragm, which can greatly extend the high frequency range and stabilize the low frequency effect, mid-frequency has high sensitivity, and decrease distortion. Ensure deep bass music.
