Definitions

  • the invention relates to a molded part for holding a Exciters for a flat membrane speaker with the features the preamble as it is from DE-OS 28 10 930 is known.
  • WO 00/52961 is a damper for one known electro-dynamic speakers.
  • the coil is now on the sound-emitting surface is fixed, e.g. about a Molded part glued, and the mass of the relative to Coil moving magnet system used to the sound emitting To vibrate the surface.
  • the invention is therefore based on the task Avoid wobble by making the transmission of vibrations on the solenoid unit if possible damping suspension is created.
  • the decoupling of a first is advantageous Area of the molded part, which is used as an adhesive flange for connection with the sound surface, for example a flat speaker panel serves with one for locking one or several magnet systems provided outer ring.
  • This outer ring is in the chosen embodiment by arranged in two levels, not straight, but curved, thin bridge bridges coupled, which, on the one hand, is distributed over the radius between the rings and on the other their spacing at more than a distance from the sound surface for one ensure cylindrical guidance of the magnet system so that Do not transmit wobble to the voice coils become.
  • the assembly of the molded part and the magnet system can be simplified by the fact that inserts to accommodate solder lugs or solder pins on the Support ring provided for the reception of the magnet system become.
  • the molding shown in Fig. 1 consists in essentially of two rings 10, 16, the inner ring 10, the one facing inwards in the figure projecting ring surface 12 an adhesive flange for connection with the sound-emitting membrane, and the is provided for receiving the voice coil, and the outer ring 16, which consists essentially only of a short cylindrical surface exists, and with approaches 18, 20 is provided on the inside, which carry the magnet system.
  • the webs 22 each run parallel in one plane to the vibrating surface so that the magnet system is flexible perpendicular to this level to its own Can use movement and the excitation of the vibrating surface. As in the figure, they can all turn in the same direction (in the figure clockwise outwards) or also such that the bridges of a group run counter to those of the other group.
  • Inner ring In its inner circumference to the - in the picture front, facing away from the sound membrane - the side has Inner ring also ventilation openings 14 that are too lateral areas of the sound surface lying next to the adhesive flange to open. These ventilation openings 14 cool the coil, which is otherwise surrounded by the magnet system.
  • the molding can also be made in 3D lithography, or from can be laser milled with a glass fiber reinforced plastic.
  • a single bridge web 22 has a curved shape of at least two bends facing each other from the straight extension can also stiffer materials are used when longer webs be provided.
  • the connection should be one Web 22 with the inner ring 10 and / or the outer ring 16 at an angle of less than 45 ° to the radius, So initially approximately at right angles with preference over the web width enlarged cross-section by which Vibrational forces that later also when operating the exciter arise to withstand particularly well.
  • the assembly of the molded part and the magnet system are further simplified by the fact that inserts 24 for receiving solder lugs or solder pins on the outer ring 16 for the inclusion of such with the magnet system prefabricated elements are provided.
