The recently established Modeling and Simulation Department at Sonion has a young and rapidly growing team with the goal to model and design innovative products for the hearing aid and pro-audio industry, such as miniaturized loudspeakers and other transducers used also in many modern consumer electronics products like smart phones, ear buds, tablets. In case of hearing aids, transducers are the main active components, and their behavior is crucial for the hearing aid performance. Therefore, a good dynamic model able to predict the behavior of the transducer under different conditions is required in order to test new designs, optimize the sound quality and reduce the product size.
Project #1 – Development of a fully coupled FEA-based transducer model
The goals of the project are:
Project #2 – Development of a MEMS microphone lumped element model
The goals of the project are to study the behavior of MEMS microphone lumped element models (LEM) with respect to the relevant parameters. Parameter sensitivity studies of the microphone LEM in OrCAD PSpice will be performed aiming at understanding the behavior of the model from Physics perspective. In particular, the microphone performance will be investigating by measuring and predicting:
Project #3 – Nonlinear material models for transducer membranes
The goal of this project is to investigate the nonlinear behavior of the sealing layer in miniaturized loudspeakers membranes and its effects on the transducer frequency response. The sealing layer, polymer-based foil with thickness ranging from 10 to 30 um, is placed on the transducer membrane to acoustically seal the front and back chamber while being mechanically transparent. A fully coupled FEA-based model will be developed by using COMSOL software.
The investigation will include the following aspects:
Sonion improves the quality of life of people using hearing products. We are committed to be the preferred partner in the development and manufacturing of transducers and electromechanical solutions designed for (professional) use in hearing instruments, in-ear earphones and hearables. Size matters and we constantly challenge the laws of physics for making small and reliable products. Our outstanding competences within customer focused innovation and development and our lengthy experience in efficient manufacturing make us successful and this will be used to expand into new business areas.
Sonion has facilities in Denmark, the Netherlands, Vietnam, the Philippines, Poland, USA and China, wherefrom the (more than 5300) Sonion employees work together across all the locations.
Of course, we offer an internship allowance. More importantly, we offer you a work environment that gives you the opportunity to steadily further develop. In this project, you will get a lot of responsibility and chances to use your knowledge in the field. You and your supervisor will regularly reflect on your work. Sonion is an international and inclusive organization where it is easy to connect with colleagues. Where are you waiting for, apply now!
