Definitions

  • the invention relates to a loudspeaker unit according to the type specified in the preamble of claim 1.
  • Loudspeaker units consisting of a frame and a loudspeaker basket, which are connected by clamps or screw connections. For mass production, especially for loudspeaker units in television sets, this results in a large manufacturing effort.
  • the object of the invention is to provide a production-technically simplified connection type of frame and loudspeaker basket.
  • the invention enables simple assembly of a loudspeaker basket in a frame provided for this purpose.
  • Fig. 1 shows a speaker basket 7 for side and front mounting with a frame.
  • Areas 5 and 6 are provided for side mounting.
  • the areas 5 consist of elevations which are conical to the edge of the loudspeaker basket 7.
  • the areas 6 of the speaker basket 7, consisting of elongated concave material cutouts, which are arranged next to the areas 5.
  • Areas 9 and a movable projection 8 are provided for the front mounting of the speaker basket 7 with a frame.
  • the area 9 is attached to a first end face of the loudspeaker basket 7 as a material continuation. It has the shape of a rectangular tongue.
  • the movable projection 8 Opposite this area 9, on the other end face of the speaker cage 7, is the movable projection 8, which has a U-shaped shape and whose first leg facing the area 9 is connected to the speaker cage 7. This first leg also has a support 13. On the other leg of the U-shaped projection 8, which is longer, there is a wedge-shaped projection 14, the tip of which is at the end of the leg and the widened area is at the level of the loudspeaker frame.
  • the frame 3 has movable areas 2, so-called snap-in, and fixed areas 1.
  • the fixed areas 1 of the frame 3 protrude into the projections 5 which open conically towards the frame.
  • FIG. 3 shows a further loudspeaker unit, the front-side connecting elements connecting loudspeaker basket 7 and frame 11 to one another.
  • the tongue-like continuation 9 of the loudspeaker basket 7 engages behind the recess 10 on the front side of the loudspeaker frame 11 during assembly recess 10 constructed like this is also present on the opposite end face.
  • the movable projection 8 engages behind this recess 10 with the widened surface of the wedge-shaped projection 14.
  • the frame 11 is constructed in such a way that the assembly of the speaker basket 7 with the frame 11 is facilitated by lateral guide webs 15. The same applies to the frame 3 with guide webs 12.
  • Fig. 4 shows a side view of a loudspeaker.
  • the loudspeaker consists of a magnet system 15, a basket 16, an upwardly flanged edge 17 and a snap-in device 8, 9.
  • a seal 18 is located on the radiating surface of the loudspeaker.
  • Fig. 5 shows a top view of the loudspeaker. As can be seen in FIG. 4, the seal 18 projects beyond the edge 17 of the loudspeaker. This causes the speaker to jam with the cover frame.
