Device for attaching a loudspeaker to a baffle

The invention relates to a device for attaching a loudspeaker to a baffle.

It is known that the loudspeakers on the baffle of a device housing of a television receiver or a radio with a built-in loudspeaker using screws or fasteners on bars to fix.

Another attachment of a loudspeaker to a baffle is known from DE-GM 77 07 939. Of the Loudspeaker reaching through the baffle has a cylindrical retaining ring, which in a cylindrical fastening ring consisting of several spring tongues can be screwed in. Of the Loudspeaker is literally attached to the baffle by twisting two fasteners into each other.

Other types of attachment consist in that a storage opening is provided on the back of the baffle which is formed from short walls protruding into the device and on the spring clip tabs can be postponed with retraction safeguards. The protruding spring tongues press on the outer edge of the horn and press the loudspeaker with the around the sound outlet opening placed pressure ring against the baffle.

The invention is based on the object of a simpler one particularly easy-to-assemble device for fastening of a loudspeaker that ensures a secure hold of the loudspeaker on the baffle even without Allows screwing or placing individual spring elements distributed around the circumference.

The object is achieved according to the invention in that the loudspeaker has one or more bow springs is spanned, the ends of which are fastened concentrically to the respective loudspeaker housing part on the baffle are, and that the loudspeaker is held exclusively by the spring and by the spring force against the Baffle is pressed.

Advantageous further developments of the invention are described in the subclaims.

When using relatively thin-walled baffles, e.g. in a television receiver, is according to claim provided to introduce through bores into which the hook-shaped ends of a bow spring can be hooked. During assembly, the loudspeaker is placed on the sound outlet opening and the bracket spring with the one end inserted into a receiving hole, pulled over the loudspeaker and the other end as well hooked into the through hole. This provides a secure hold, and with appropriate dimensioning the tavern hanging the hook-shaped ends, an increased pressure is exerted on the loudspeaker and this pressed against the baffle.

The invention is explained in more detail below with reference to the exemplary embodiment shown in FIGS.

In Fig. 1, the essential parts to be connected are shown. On a baffle 1 should be above Drawn loudspeaker 2 are firmly connected by means of the bow spring 4 drawn above it. In Fig. 2, the assembled state is shown. In the baffle 1 is a sound outlet opening 1.0 provided, over which a loudspeaker 2 is placed concentrically with a round bell. On both sides of the speaker 2 through holes 3a and 3b are provided. The loudspeaker shows, for example electromagnetic transducer system 6 on / which is arranged centrally. After putting on the loudspeaker on the sound outlet opening 10 is the bow spring 4 with its end 8, which is as a hook-shaped End is formed with a certain length, inserted into the through hole 3a. When depressing the bow spring 4 engages the arcuate center piece on the contoured magnet system 6, so that the annular part of the bow spring can be supported on the outer pressure ring of the horn 11. The second end 9 of the bow spring is then inserted into the through hole 3b. Grab the free legs while under the baffle, so that both the bow spring held by the spring tension and a sufficient one Pressure force is exerted on the loudspeaker 2 so that it rests firmly on the baffle 1 .. In the illustrated embodiment, the bow spring 4 consists of a shaped spring, which corresponds to the drawn Is formed contour. In the case of using a loudspeaker with an oval bell shape or Elliptical shape are either such a spring for attachment provided over the narrow side of the loudspeaker or several over the long sides of the loudspeaker distributed.

summary

The device for attaching a loudspeaker to a baffle consists of a loudspeaker spanning bow spring, the ends of which are arranged concentrically to the loudspeaker on the baffle Attachment points are attached.

For loudspeakers with elliptical horns several bow springs are provided depending on the size of the loudspeaker.
