Patent number: 10645508Abstract: A method for manufacturing an electrodynamic transducer from a membrane system module and a magnet system module is disclosed. The membrane system module comprises an annular first chassis unit made by injection-molding and a diaphragm fixed thereon. A coil is fixed on a coil seat of the diaphragm. The magnet system module comprises a pole piece, a magnet and a yoke that each have a central hole, and a second chassis unit that is made by injection-molding and that fills the central holes in the pole piece, the magnet and the yoke. It surrounds the yoke at least partially, so that the pole piece, the magnet and the yoke are held. In the transducer, the membrane system module and the magnet system module are plugged together, wherein an annular recess on the lower side of the first chassis unit is arranged on a circumferential shoulder of the second chassis unit. This defines a position of the coil relative to the pole piece, to the magnet and to the yoke of the magnet system module.Type: GrantFiled: September 5, 2017Date of Patent: May 5, 2020Assignee: Sennheiser electronic GmbH & Co.

Patent number: 7505151Abstract: The invention relates to an arrangement for optically determining the distance of a reflecting surface that can be used, in particular, for determining slight variations in distance such as can frequently occur in vibrating systems. Such an arrangement can also be used as optical microphone or hydrophone. The arrangement according to the invention is designed in this case such that light from a light source is directed onto a reflecting surface via a first optical fiber, and light reflected therefrom is directed onto at least one statically arranged optical detector via the first optical fiber or at least one further optical fiber. An optical element collimating in the direction of the reflecting surface is arranged between the reflecting surface and the one or more optical fibers.Type: GrantFiled: April 2, 2004Date of Patent: March 17, 2009Assignees: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung e.V., Sennheiser Electronic GmbH & Co.

Patent number: 6210241Abstract: Electrical contacting of very fine wires, including an electrical transducer and an electrical apparatus, as well as a process for producing the electrical contacting of very fine wires. It is the goal of the invention to simplify the electrical contacting of very fine wires to the contact sleeve and make it more secure, so that an automatic is possible and the production costs for the electrical contacting are reduced. According to the invention, for the accomplishing of the set task an electrical contacting of a very fine wire is proposed, in which contacting the contact sleeve shows two superimposed plates and provision is made for a clamp region of the plates, in which region the plate spacing is less than in the other plate regions. In the clamp region the wire is clamped in between the plates and connected to at least one of the plates in an electrically conducting manner. Advantageous further developments are described in the dependent claims.Type: GrantFiled: June 26, 1998Date of Patent: April 3, 2001Assignee: Sennheiser Electronic GmbH & CO KGInventor: Andre Michaelis
