Nano-Crystal Coating Composite Diaphragm
10mm Composite Cavity Dynamic Structure:Adopting the Aria’s decentralized dynamic structure, the high-performance 10mm composite cavity with high-frequency phased waveguide leverages a N52 Nd magnet internal magnetic circuit and 0.035m ultra-thin imported CCAW sound coil to obtain high energy conversion efficiency, and deliver outstanding performance with full dynamic range and rich details.
Accurate Calculatioof Acoustic Coupling Cavity:In order to match the frequency response as closely as possible to the VDSF Target Response, the acoustic coupling cavity needs to be carefully controlled. Through volume and dimension calculation, FEA finite element simulation and 3D printing experiment verification, an acoustic coupling cavity has been created which can accurately reproduce the ideal frequency response.
