Definitions

  • a loudspeaker unit generally consists of a frame serving as a sound guide with a sound passage opening and a loudspeaker attached to it.
  • the frame can e.g. the front frame of a television receiver, the front wall of a loudspeaker box, the wall of a radio or the dashboard of a car.
  • speakers with a plastic basket and a metal basket are optionally used, so that it may be necessary to provide different types of mounting.
  • the invention has for its object to provide a frame for a loudspeaker in such a way that loudspeakers can optionally be attached to the same frame using a positive locking connection and a screw connection.
  • the solution according to the invention optimizes both types of fastening, namely that by means of a positive locking connection without screws and that with screws on the same frame.
  • the same frame can therefore be used for both types of fastening, which is particularly advantageous for the manufacture and storage of the frame.
  • Both types of attachment can be done by a translational movement of the speaker, i.e. a movement in which all points of the speaker move in a straight line. This is particularly advantageous for installing the speaker with machines.
  • Fig. 1 shows the front frame 1 of a television receiver with the sound passage opening 2 for an oval speaker.
  • a rigid projection 3 is provided with an opening 4, which forms a molded plastic part with the frame 1.
  • a projection 5 is provided at diametrically opposite points of the opening 2, which protrudes from the plane of the frame 1, is formed resiliently by a slot 6 in the direction of the plane of the frame 1 and has a barb-like projection 7 with a bevel at its upper end .
  • the frame 1 is also four Provide threaded holes 8 for receiving self-tapping screws.
  • the loudspeaker For the attachment of a loudspeaker with a plastic basket in the sense of a positive locking connection without screws, the loudspeaker is placed on the frame in the direction perpendicular to the plane of the frame 1. Resilient projections on the basket of the loudspeaker are deflected by the projections 3 until barb-like ends of the projections on the loudspeaker finally snap into the openings 4 of the projections 3. The loudspeaker is then held on the frame 1 in a form-fitting manner and without play. The projections 5 on the frame 1 are not required and are of no importance for the mounting of the loudspeaker.
  • the attachment of a loudspeaker via a positive locking connection, a so-called snap-in, without screws to the front frame of a housing of a television receiver is described in DE-GM 84 02 128.
  • the loudspeaker is also placed in the direction perpendicular to the plane of the frame 1.
  • the flange of the loudspeaker first meets the lugs 7 and causes the resilient projections 5 to deflect radially to the opening 2.
  • the flange of the loudspeaker engages in the slots 6, and the loudspeaker is now on the frame through the projections 5 1 held.
  • This bracket is not a final attachment, but is only used for a position fixation, also called pre-fixation, in a position in which holes in the flange of the loudspeaker correspond to the threaded bores 8.
  • the loudspeaker then no longer needs to be held for the screwing process, so that the operator has both hands free for the screwing process or the screwing process can be carried out with automatic machines.
  • two or four screws are screwed through the holes in the flange of the loudspeaker manually, with a hand screwdriver or with automatic machines into the threaded bores 8, as a result of which the loudspeaker is finally attached to the frame 1.
  • the projections 5 used for temporarily fixing and holding the position are then no longer of importance for fastening the loudspeaker.
  • the projections 3 are of no importance in this type of attachment. They can also serve as a guide and as a stop for the flange of the speaker.
  • the projections 3, 5 are offset from the long axis of the oval-shaped opening 2 by an angle of approximately 15 °. This has the following advantage: If the protrusions lie exactly in the direction of the long axis, the space requirement in the direction of this long axis would be greater. This is particularly disadvantageous in the case of a television receiver in which the space for mounting the loudspeaker is limited.
  • the offset position in relation to the long axis allows space to be gained. This means that the distance between the two projections 3 or 5 from each other is reduced in the direction of the long axis A.
