Demo Videos of the KLIPPEL QC System

This interactive demo tour gives an overview on the basic functionality of the KLIPPEL QC System. It demonstrates the intuitive user interface of the QC Operator mode. Furthermore, it shows how to easily set up comprehensive tests in the QC Engineer mode. Finally a selection of setup parameters is examined.

In this demo tour a comprehensive approach on testing active full range audio systems with the KLIPPEL QC System is presented. The measurement setups in includes multiple microphones for near field (Rub&Buzz, air leakage) and far field (windowed frequency response) measurements with full ambient noise immunity.

This demo video focuses on end-of-line testing of built-in speakers of mobile devices such as smartphones. The test signal generated by the KLIPPEL QC system is exported to a WAVE file and copied to the device under test for stand-alone playback. Using the External Synchronization feature, the analysis is triggered as soon as the unique synchronization signal is detected.

This demo video focusses on high-speed testing of loudspeaker systems with integrated audio interface. Using 3rd party audio devices in Klippel QC reveals the delay due to driver, signal processing etc. The unknown and varying delay of those devices may be detected and compensated using the SYN (External Synchronization) feature.

The  Balanced  Armature  Check  is  a  unique  measurement  tool dedicated to testing electro-magnetic transducers on the production  line.  The  armature  offset  in μm  and  effective  linear parameters are determined from a purely electrical high-speed measurement.  This  gives  valuable  diagnostics  information  to minimize rejection rate.

This demo video shows how to test microspeakers with the Klippel QC System. An exemplary hardware setup is introduced where the driver is operated close to the conditions in the final application.

In the test sequence different measurement modules (Motor+Suspension Check, Impedance and SPL) are combined to assess the electrical small and large signal behavior as well as the acoustical output for comprehensive testing. 

Besides detecting acoustical symptoms like Rub&Buzz distortion with high sensitivity also the causes can be spotted. Large signal parameters like voice coil offset or stiffness asymmetry may easily uncover defects and production drifts - even before problems get audible.
