    摘要： A dynamic electroacoustic transducer includes a moving coil which is arranged in an air gap between a pole piece and a pole plate which is filled with a magnetic liquid. At least the outside of the coil has a smooth surface in contact with the magnetic liquid. The coil may also advantageously be wound on a carrier from a wire which is flat at least on one side so that this flat side is turned outwardly and presents a smooth continuous surface. The cross-section of such a wire may advantageously be rectangular. The coil may be coated on its outside surface with a foil of well-conducting material, such as aluminum, or the grooves between a cylindrical coil, for example, may be filled with a lacquer or the like.

    摘要： A membrane for a loudspeaker is designed so as to facilitate manufacture and to improve the tone of the loudspeaker. The membrane consists of a first plastic film (5a) which serves to retain the shape and a second plastic film (56) laminated to the first film which serves to damper partial oscillations. The membrane is particularly suitable as a conical membrane for a loudspeaker for a television receiver.

    摘要： A Passive loudspeaker enclosure for a television receiver. Interference in the reproduced picture caused by magnetic stray fields from the enclosure occurs, in particular, with color television receivers with 33 inch picture tubes. The task is to reduce the magnetic stray fields by employing simple measures and without using additional components until the interference no longer appears in the picture. In particular, for a loudspeaker enclosure in a television receiver with a 33 inch picture tube.

    摘要： A dynamic electroacoustic transducer comprising a magnetic pole case defining a magnetic air gap, a coil movably mounted in the air gap and spaced from the magnetic pole case with magnetic liquid extending between the coil and the case in the air gap. A diaphragm is connected to the coil and attached peripherally to the magnetic pole casing so that airtight spaces are defined above and below the coil which are in communication with each other. The airtight sealing of the spaces prevents the liquid portions of the magnetic liquid to evaporate which would result in deterioration of the characteristics of the dynamic electroacoustic transducer.

    摘要： Loudspeaker unit including a frame (FIG. 2) serving as sound guide to which the loudspeaker chassis (FIG. 1) is releasably fastened. According to the invention, form-locking cooperating detent means (4-6, 29-31) are provided on the frame and on the loudspeaker chassis. The loudspeaker chassis can be inserted into the frame by means of a relative translatory movement and can be removed by a rotational movement. Thus it becomes possible to install the loudspeaker in the frame and remove the loudspeaker from the frame by means of automatic machinery.
