DC Arc Plasma Jet is the only technique which can be used for high quality diamond film deposition at high growth rate. Thus it is ideal for the preparation of freestanding diamond domes for high performance loudspeakers.

Applications

CVD diamond tweeter domes are suitable for high performance loudspeakers. The domes are made by DC Arc Plasma Jet, which guaranteed the conformal high quality growth of synthetic diamond on a 3-D carrier. The synthetic diamond could subsequently be removed from the carrier as free-standing domes, free of cracks, and with high yields.

Advantages

High quality semitransparent polycrystalline diamond

Excellent thermal stability and high thermal conductivity

High cone break-up frequency

Low total harmonic distortion (THD)

High power tolerance
