  • Product description:
  • The Application for High-pitched Loudspeaker Film

    CVD diamond (Lab Grown Diamond) has high elastic modulus and low mass density. It is the fastest acoustic propagation materials, and longitudinal wave velocity is as high as 18000 m/s, which is three times more than common diaphragm material AI and Ti. So CVD diamond is an ideal material to making high fidelity acoustics devices. Although the sound propagation speed of material Be is not low, the toxicity of Be has greatly limited its application.

    A 26mm diameter speaker film, made of CVD diamond, has its crossover frequency up to 70kHz, which is more than twice as much as AI and 40% higher than Be.


    Frequency of the diaphragm is high, low total harmonic distortion, high power bearing capacity.


    The film for High-pitched Loudspeaker, etc.
