Definitions

  • the invention relates to a loudspeaker with a bayonet catch, that is to say a loudspeaker which is fastened to a holding device by being axially pushed into it and then rotated through a small angle.
  • Speakers with a bayonet catch have bayonet catches on a circular fastening ring at the end of the loudspeaker that is furthest forward in the direction of radiation. This end is referred to below as the front end.
  • the terms "front” and “rear” are to be understood in accordance with this definition.
  • loudspeakers with a bayonet lock have poorer acoustic properties than loudspeakers with other fastening devices, in particular loudspeakers that are fastened with screws. Speakers with a bayonet lock were therefore not used for high quality speaker systems. Due to the fact that there are low installation costs compared to other speakers with bayonet locks However, there has long been a desire to have loudspeakers with a bayonet lock that have the same acoustic properties with an otherwise identical construction as loudspeakers with other types of fastening, in particular loudspeakers that are fastened with screws.
  • the loudspeaker with bayonet lock has, in addition to several bayonet lock lugs on the circular fastening ring, a projection device which projects further from the fastening ring than the locking lugs and extends further in the radial direction than the locking lugs, so that the projection device at least then covers the insertion slots of the holding device to the rear, if the loudspeaker is hidden in its mounting position in the holding device, and whose front surface lies further back than the rearmost point of the locking lug.
  • the projection device designed in this way serves to cover the insertion slot in the holding device, which allows an acoustic connection between the sound spaces in front of and behind the loudspeaker in conventional loudspeakers with a bayonet lock.
  • the inventors have found that it is this connection which, in particular in the case of open loudspeakers, leads to the observed deteriorations in acoustic behavior, as described above, compared to loudspeakers which are fastened differently.
  • These previously unclosed insertion slots result in a so-called acoustic short circuit when using open speakers, while an acoustic leak occurs when using closed speakers.
  • the projection device can be produced particularly cost-effectively if it consists of only one individual projection, which is only slightly longer in the radial direction than the locking lugs are.
  • This embodiment requires the least amount of material, but is the user forced to design the holding device so that when the speaker is attached, the individual projections just cover the associated insertion slots. If, on the other hand, the projection device is designed as a radially circumferential projection, the material expenditure is high, but the user does not have to pay attention to the direction of rotation and the extent of the rotation as they are to be observed during the fastening process when designing his holding device.
  • the holding device 11 shown in FIG. 1 apart from an open loudspeaker 10 consists of a plate with a holding ring 13, the inner diameter of which corresponds to the outer diameter of a fastening ring 14 on the loudspeaker 10.
  • insertion slots 15 in the axial direction with subsequent securing grooves 16 in the radial direction.
  • the slot arrangements are arranged at mutual angles of 90 °.
  • four bayonet locking lugs 17 are arranged at a mutual angle of 90 °. You jump so far from the mounting ring 14 that they can be inserted into the insertion slots 15 and then rotated until crests 21 of the locking lugs 17 snap into the locking grooves 16.
  • the loudspeaker 10 with the associated holding device 11 is identical to arrangements known from the prior art.
  • the locking tabs 17 and the twist slots 16 have any known shape which ensures secure holding in the twisted state, e.g. B. 17 caps are present on the locking lugs, which snap into associated recesses in the twist slots when the speaker is rotated sufficiently far after inserting the locking lugs into the insertion slots.
  • the insertion slots 15 are free, which is why sound through these slots along the double arrow 18 shown on the right in FIG. 1 on the holding device 11 from the room in front of the holding device into the room behind Retaining device and vice versa, if there were not four projections 19 on the mounting ring, which are just arranged so that they cover the insertion slots 15 to the rear when the speaker 10 is rotated into its mounting position.
  • the projections 19 thus connect in the radial direction against the direction of rotation to the respectively adjacent locking lug 17, as is the case here Fig. 1, but in particular also from Fig. 2 can be seen.
  • each projection 19 lies further back than the rearmost point 21 of the locking lugs 17.
  • the distance corresponds to the distance of the rear edge of a twist slot 16 from the rear edge of the retaining ring 13. So that the projections 19 reliably cover the associated insertion slot 15, jump further from the fastening ring 14 than is the case for the locking lugs 17.
  • the loudspeaker 10 according to FIGS. 1 and 2 is only designed for a single direction of rotation during assembly. If the direction of rotation is to be left free for the user, a construction as shown in FIG. 3 is advantageous. This has two projections 19 adjacent to each locking nose 17, which two projections in the exemplary embodiment are offset by the same angle in opposite directions radially with respect to the adjacent locking nose 17. When using this embodiment, however, the user must still make sure that his holding device is designed so that rotation is only possible by the angle that ensures that when the speaker is attached, one of the two projections 19 with a locking lug 17 above the associated insertion slot 15 is located.
  • the direction of rotation and the extent of the rotation are entirely at the discretion of the user when using an embodiment as illustrated by FIG. 4.
  • the projection 19 ' is radially circumferential.
  • the projection 19 will only protrude a little more than the fastening 14 than the locking lug 17 and the projection 19 will be only slightly wider in the radial direction than the locking lug 17, at its width the insertion slots 15 are adapted.
