measurements, diagnostics, analysis

´The R&D system provides tools dedicated for the research  and  development  of  loudspeakers  and  other kinds of audio products. The main purpose of the R&D system is to accelerate hardware and software development  to  create  products  which  satisfy  customer demands for the lowest possible manufacturing cost.Yes, the R&D system performs comprehensive analysis of  prototypes  and  provides  meaningful  data  that  is easy to compare and interpret, but it is more than just a measurement  instrument.  New  identification  techniques  provide  nonlinear  parameters  required  for numerical model analysis and simulation. New auralization  techniques  combine  objective  evaluation  of design  choices  with  listening  tests  and  perceptual evaluation. The R&D system allows you to express the target  performance  with  comprehensive  repeatable numerical specifications, which is what is required to have a clear vision of the future product and to have the product tuned to the intended market.

With the R&D system you create an inspiring environment for the design engineers to discover and evaluate new ideas.

Defect Diagnostics, Test Automation, Process Control

The  KLIPPEL  QC  System  satisfies  the  particular  demands at the end of the assembly line and in routine tests used in pilot runs preparing for manufacturing. It is a modular system to realize cost effective solutions for all kinds of audio devices under test such as transducers  (micro-speaker,  woofer,  tweeter),  passive  systems (speaker box, headphones) and active audio systems (speaker system, tablet, smart phone). Contrary to the R&D, the QC System hides the complicated physics and  provides  a  simplified  user  interface  with  the  necessary  results  required  for  manufacturing. 

The  QC System  satisfies  not  only  the  demand  for  detecting defective  units  reliably  even  if  the  symptoms  are  not audible in a noisy production environment, but also focuses on the ultimate goal to increase the yield rate in manufacturing.  End-of-line  testing  provides  valuable diagnostic information for detecting the root cause of the problem and allows you to fix the problem as soon as possible. While human testing at the end-of-line is replaced by automatic QC systems, the operator is required to perform a visual inspection of the defective unit  at  the  diagnostic  station.  This  provides  valuable information  for  process  control  and  feed-back  to  the R&D engineers developing future products.
