Presentation Transcript

  1. The following slides are part of a presentation by Peter Larsen, LOUDSOFT on the ALMA Workshop, FEA Analysis for Loudspeakers, Las Vegas, January 5, 2005. FINECone™Proof af Accuracy

  2. FINECone 2D FEA Analysis of 165mm Woofer Pink: Measured responseBlack: Simulated High Accuracy from 200-10kHz

  3. The problem is found!Cone + Surround Break-up @ 1617Hz

  4. FINECone Simulated solution:Modified Surround The cone break-up is now removed!

  5. FINECone Simulated solution:Modified Surround (black)High Accuracy from 200-10kHz

  6. FINECone 2D FEA of 2 inch / 50mm Alu DomeRear cavity includedPink = MeasuredHigh Accuracy from 2-15kHz

  7. FINECone Simulated Impedance (Black)High Accuracy 20-20kHzPink = Measured

  8. FINECone can be used for significant analysis and design of the acoustical components in loudspeakers FINECone can accurately simulate and predict break-up in loudspeakers. FINECone is a valuable design tool for loudspeaker engineers FINECone can find the problems in your speakers and can help you find the solution Summary
