Abstract: 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.

Abstract: A microphone having a microphone capsule is provided. The microphone capsule has a diaphragm carrier, a diaphragm and an adhesive tape ring which is used to fasten the diaphragm to or in the diaphragm carrier. The microphone capsule is in the form of a dynamic sound transducer. A dynamic sound transducer for headphones, earphones or headsets is also provided. The sound transducer has a diaphragm carrier, a diaphragm and a moving coil which is coupled to the diaphragm. In a similar manner to the microphone capsule, the sound transducer has an adhesive tape ring between the diaphragm and the diaphragm carrier, which ring is used to fasten the diaphragm to the diaphragm carrier.

Abstract: An ear canal earpiece comprising an electroacoustic sound transducer, a first sound guide unit for guiding the sound from the electroacoustic sound transducer, a second sound guide unit for prolonging the first sound guide unit, a third sound guide unit whose outside contour is matched to an inside contour of an ear canal of a user and which surrounds the second sound guide unit, and a sound wall in the region of the second sound guide unit, wherein the sound wall extends between the second and third sound guide units.

Abstract: A planar dynamic sound transducer comprising a planar diaphragm with at least one electrical conductor and at least one planar magnet arrangement which is disposed parallel to the diaphragm and which is in the form of a continuous magnet disk. The magnet disk has a first side facing towards the diaphragm and a second side facing away from the diaphragm. The magnet disk has, on the first side, in an alternating strip-wise relationship, regions which are magnetized as a North pole and regions which are magnetized as a South pole. The magnet disk, on the second side, has a plurality of openings or recesses which are arranged that they are respectively opposite the regions magnetized as the North and South pole respectively.

Abstract: A microphone having a microphone capsule (10) is provided. The microphone capsule (10) has a diaphragm carrier (40), a diaphragm (20) and an adhesive tape ring (30) which is used to fasten the diaphragm (20) to or in the diaphragm carrier (40). The microphone capsule (10) is in the form of a dynamic sound transducer. A dynamic sound transducer for headphones, earphones or headsets is also provided. The sound transducer has a diaphragm carrier (40), a diaphragm (20) and a moving coil (22) which is coupled to the diaphragm. In a similar manner to the microphone capsule, the sound transducer has an adhesive tape ring (30) between the diaphragm (20) and the diaphragm carrier, which ring is used to fasten the diaphragm (20) to the diaphragm carrier (40).

Abstract: There is provided a wireless headphone unit having at least one electroacoustic transducer and a transmitting/receiving unit for wirelessly receiving first signals which contain audio signals to be reproduced on the electroacoustic transducer and a network identification unit for storing the network identification of the wireless headphone unit, wherein the transmitting/receiving unit is adapted for wirelessly transmitting the network identification of the headphone unit.

Abstract: There is provided an in-ear earphone comprising a housing having at least one electroacoustic transducer, a control unit which outputs a test signal to the electroacoustic reproduction transducer for reproduction, and a tightness measuring unit for measuring a parameter representative of the tightness of a fit of the earphone in an ear canal. The control unit is adapted to output a second audio signal as confirmation of a tight fit of the earphone to the electroacoustic reproduction transducer for reproduction.
