Sennheiser is active in the areas of research, development, production and sales of electro-acoustical products such as microphones, headphones, loudspeakers. In particular, Sennheiser’s Professional Systems division serves the areas of Professional Audio and Broadcasting, Live Sound, Studio and Recording, Conference and Interpreter Systems. Sennheiser’s Consumer Electronics division develops Headphones for private customers, audiology and telecommunication products.
Sennheiser contributed to REProMag by formulating use cases and providing industrial applications, along with the ability to evaluate and support the progress and results of the project. Sennheiser also evaluated the feasibility of the applications shown in the demonstrator descriptions.
We spoke with Harald Sander-Röttcher, Manager of the Research & Innovation team at Sennheiser:
How did you come to hear about the project REProMag? What convinced you to get involved?
We were looking for someone who could manufacture our magnet plate with slits from sintered magnet material and not from plastic filled material. We came across the Austrian company FOTEC which told us there will be a EU funded project led by the German company OBE with the target to develop the process to manufacture arbitrarily shaped sintered magnets without producing waste. After a meeting with Carlo Burkhard from OBE, we decided to join as industry partners.
Which advantages are there for your organisation in REProMag?
Sennheiser is involved in REProMag as industry partner, that is to say we developed use cases and industrial applications for the SDS magnet parts, as potential future customers. We need arbitrarily shaped magnets for some of our products and innovations and evaluated the feasibility of the REProMag demonstrators, such as a magnet disk for planar transducer. We could get deeper insights in the technology and supply situation of rare earth magnets. We also have now a more precise idea of how we can reach the required performance from the material and the shaping process.
Is REProMag your first H2020 project? Your feedback on the project: Are you satisfied with it, would you do something differently if you could start again at day one?
Yes, it is our first Horizon 2020 project. We are very satisfied with the organisation, the coordination, the project management and of course the fantastic experts we met. This was a great insight in faculties we normally do not deal with. Unfortunately, due to technical issues the final parts currently not match the expected quality. But we expect that these issues can be overcome in the near future and the developed technologies will be a great success.
