Virtual Voice Coil (VVC) is the software devoted to loudspeaker design for Woofers, Midranges, Tweeters, Compression Drivers, Headphones, Micro Speakers, etc.
With VVC is possible to select built-in wires or to create new sheets with custom round, square or rectangular wires.
7 different wire materials (Copper, Aluminium, CCAW, HCCAW, UCCAW, Silver, Gold), 11 former materials and 22 reinforcement tape materials. Materials resistivities and densities are automatically updated on all voice coil and loudspeaker parameters.
Circular, Square and Rectangular voice coil shapes, up to 20 layers, selecting Diamond or Hexagonal round wire winding configuration. Series, Bifilar, Parallel plus all combinations of Series-Parallel multilayers connection with a design aid tool. Possibility to define vent holes, copper pads and cuts on voice coil former, or customize exit wire leads with a dynamic regulation of maximum allowed dimension.
Importing the flux density profile from external FEA software (accepting both period or comma decimal separator) is possible to analyze B(x) & Bl(x) asymmetries, permitting to optimize loudspeaker motor design and select the best balance for improving XBl and reducing related non-linear distortions.
All new features added to the differential environment temperature allow a more precise value of the transducer parameters and SPL. Membrane force direction audit avoids errors on the loudspeaker phase response.
±XBl displacement and the Maximum Available mechanical eXcursion (MAX) are constantly updated for any parameter or virtual offset change. The loudspeaker suspensions compliance separation permit to find single component and system resonance frequency. The new surround and spider rates measure their contribution on total suspension system. Moving mouse over voice coil elements or transducer Thiele & Small parameters instantly plot the variation for available wires. Wire Loss and SPL charts permit to maximize transducer efficiency, then the HTML report is useful to export or share graphs and parameters.
