ISEAT 2025
General Information Venue:
| The 10th International Symposium on ElectroAcoustic Technologies (ISEAT) is taking place from 8th to 9th November 2025 in Shenzhen, China. Organised by the Shenzhen Research Institute of Nanjing University and hosted by Professor Shen Yong of Nanjing University, ISEAT serves as a leading international platform for academic exchange in electroacoustics and related fields. Since its inception in 2007, the symposium has been held every other year and has established a strong worldwide reputation in the field of electroacoustics and its peripheral domains. The event brings together famous experts, industry leaders and senior engineers from all around the globe to discuss the latest advancements in technologies, materials, and equipment. We are proud to announce that our colleague Jonathan Gerbet will present his paper “Validating Nonlinear Transducer Motor Simulation with Measurements”. His contribution highlights the application of a fast, full dynamic, and non-destructive measurement technique developed by KLIPPEL to validate a COMSOL-based FEA simulation of the position-dependent force factor (Bl(x)) and the frequency- and the position-dependent lossy self-inductance (ZL (f,x)). |

Validating Nonlinear Transducer Motor Simulation with Measurements
Saturday, November 8th, 2025 from 11:00 am to 11:40 am by Jonathan Gerbet (KLIPPEL GmbH, Dresden, Germany)
Abstract: Finite Element Analysis (FEA) is a powerful tool for predicting the behavior of electro-dynamic transducers without the need for numerous physical prototypes, significantly reducing both cost and development time. However, validating FEA results remains challenging and time-consuming. In this paper, a fast, full dynamic, and non-destructive measurement technique developed by KLIPPEL is applied to validate a COMSOL-based FEA simulation of the key nonlinear transducer motor parameters: the position-dependent force factor (Bl(x)) and the frequency- and the position-dependent lossy self-inductance (ZL (f,x)). The study compares the nonlinear motor parameters obtained from both measurement and simulation. It further identifies which of these parameters are most critical for accurately predicting transducer behavior, particularly with respect to nonlinear distortion generation and voice coil stability.
