ALTI Expo 2022

At the begin of June we will be exhibiting at ALTI Expo 2022 with our north american distributor Warkwyn. Visit us and our Multi-Scanning Workbench at our booth. Currently our engineer Stefan Irrgang is already preparing his part for the popular Speaker Builders Workshop for you. ➥ Further information on the ALTI Expo website.

KLIPPEL at Speaker Builder Workshop  
Date: June 5th, 2022

At 8:30 am - 9:00 am - Modeling and Simulation of Linear Speaker Behavior by Stefan Irrgang

At 9:15 am - 9:45 am - Overview on Measurements of Parts by Stefan Irrgang 

At 9:45 am - 10:15 am - Evaluation of the Prototype by Stefan Irrgang 

Abstract:There are many unnecessarily complicated steps between receiving the customer’s specification and building a prototype that “hits the bullseye.”  In this presentation, the student will learn how the innovative “Klippel Approach” reduces and even eliminates the costly iterative process of building numerous expensive and time-consuming prototypes before meeting the customer’s expectations.  The Klippel Approach combines a unique and novel combination of various modelling programs readily available from numerous vendors and accurate component parts measurement.  The result a is significantly shortened product development timeline.  The student will learn how the Klippel Approach yields the most direct, accurate, and quickest path from concept to marketplace.

Multi-Domain Transducer Measurement  - June 6th, 2022 at 11:00 am - 12:00 am

Description: Electro-acoustic transducers used in loudspeaker systems typically translate an electrical signal into acoustic sound by mechanically actuating a diaphragm or cone with an electro-magnetic motor. Comprehensive transducer testing therefore requires a multi-domain approach with measurements in all relevant domains: electric, mechanic, acoustic, and magnetic.

A broad range of measurements and methods will be shown including single point measurements, distributed measurements (laser scanning) and measurement methods based on model fitting for linear as well as non-linear behavior. The multi-domain measurement approach provides a wealth of relevant data, enables a much deeper understanding of the transducer, its behavior and its defects, and enables symptoms to be linked to their actual root causes. The presented measurement methods are in most cases faster than traditional measurements and only require normal semi-reverberant rooms with minimal acoustic treatment. This enables savings in time and resources both in the short and long run by reducing measurement time, eliminating the need for special facilities like anechoic rooms and, cutting down research time and the amount of necessary prototype iterations.

This presentation discusses important electrical, mechanical, and acoustical measurement performed on the KLIPPEL Multi-Scanning Workbench according to IEC 60268-21 and 22. Kent Peterson will be joined by Dr. Stefan Irrgang of Klippel GmbH.
