Definitions

  • the front panel can e.g. the front frame of a television receiver, the front wall of a loudspeaker box or the dashboard of a car.
  • the invention has for its object to provide a structurally simple and manual or automatic attachment that can be produced quickly, which is particularly suitable for small tweeters such as Piezo tweeters are suitable.
  • the loudspeaker can be attached to the front frame by means of a pure translational movement, without further rotary or tilting movements being necessary. This is particularly advantageous when installing with machines.
  • the loudspeaker can also be detached from the front panel just as easily by removing the ends of the springy fingers from the edges with a tool through an opening in the arms.
  • the invention is particularly advantageously applicable to small tweeters such as a piezo tweeter in the front panel of a television receiver.
  • Fig. 1 shows a front panel 1 with the sound passage opening 2 and two rigid arms 3, which are perpendicular to the front panel 1 and have angled ends 4.
  • the front ends 5 of the ends 4 run at least partially obliquely outwards.
  • the loudspeaker 6 with the sound guide 7 and the magnet 8 is placed on the front plate 1 in the direction 9 by a pure translational movement.
  • Resilient fingers 10 are provided on the loudspeaker 6 at opposite ends, which initially slide along the inclined end faces 5 of the arms 3 during insertion, are thereby deflected radially inward in the direction of the axis 11 and then engage in a form-fitting manner behind the angled ends 4 of the arms 3.
  • the seal 12 between the front flange of the loudspeaker 6 and the front plate 1 serves to compensate for tolerances, to hold the loudspeaker 6 without play on the front plate 1 and to provide an airtight seal.
  • FIG. 2 shows a top view of FIG. 1.
  • openings 14 are provided at the rear end, through which the ends of the fingers 10 can be removed using a tool for removing the loudspeaker 6 by radial deflection in the direction of the axis 11 can be detached again from the angled ends 4, so that the loudspeaker can be removed from the front plate 1 against the direction 9.
  • the front flange of the loudspeaker 6 contains two bores 15 which are widened towards the end at opposite points. These serve for the engagement of an auxiliary tool ges or a machine for exact centering of the speaker 6 relative to the front panel 1 during installation.
  • Fig. 4 shows the speaker 6 in a perspective view.
  • the fingers 10 are provided with barbs 16 and extended towards the rear end, that is to say upwards. These extensions form handles 17 with which the loudspeaker 6 can be manually detached from the frame 1 by deflecting the fingers 10.
  • the seal 12 is formed by a pad made of foam rubber, which has an opening in the area of the sound guide 7.
  • the frame 1 contains a box-shaped attachment, the walls 19 of which form the projections with edges 18.
  • the seal 12 lies on the surface of the frame 1, the sound guide 7 and the opening 2 matching.
  • the barbs 16 engage in openings 18 of the projections 3 by first deflecting the fingers 10 inwards and then engaging them positively in the openings 18 with the barbs 16. If the speaker 6 e.g. To be removed from the frame for repair, the rear-facing handles 17 of the two fingers 10 are moved inwards by hand so that the barbs 16 come free from the walls 19.
