BLAUPUNKT-WERKE GMBH, 3200 Hildesheim, Germany Device for attaching a loudspeaker

The invention is based on a device for attaching a loudspeaker according to the genus of Main claim.

The usual fastenings for speakers, for example by screwing them to the rear the baffle, cause difficulties when the back is difficult to access. This difficulty occurs particularly when installing loudspeakers in motor vehicles, for example when the baffle consists of the inner wall of a vehicle door or the parcel shelf.

For quick and permanent attachment of loudspeakers on baffles that are difficult to access, it is already known to insert the loudspeaker into the installation opening insert the baffle from its front. A retaining ring is attached to the end of the loudspeaker frame for this purpose provided that a centering ring that fits into the installation opening of the baffle and

"■ has a flange edge protruding radially outwards and resting on the baffle * Expanding springs receding into the recesses and then rebounding radially behind the SchallWaild jump from the central frieze ring during insertion into the installation opening, which are used to secure the loudspeaker to the baffle A retaining ring with a radial ring flange is provided, which ^{covers the edge of the opening of the 1} "baffle and at the same time holds the loudspeaker. To do this, it is necessary to permanently * · - connect the opening edge of the loudspeaker frame to the retaining ring, which is usually done by gluing.

^ 5 The object of the invention is to make this operation in the to save significant amounts, especially the handling of potentially harmful adhesives and solvents to avoid.

This object is achieved according to the invention in that several elastic fastening parts are provided are, which each have a plurality of locking springs that the fastening parts are arranged on a retaining ring are that at least one locking spring each one (ι 25 fastening part holds the loudspeaker on the retaining ring and that at least one more detent spring each

The same parts are provided with the same reference symbols in the figures.

1 shows a section through a device according to the invention (") 25. Manufactured from spring steel Fastening parts 1 are distributed, for example, at intervals of 120 on the circumference of the loudspeaker 2. With a U-shaped bent tab 3, the fastening part is opened from the inside during assembly a flange-shaped part of a retaining ring 4 is attached. The retaining ring 4 is made of; made of suitable plastic, also does not have one shown in FIG. 1 speaker cover shown and can be expanded to a tubular housing part 5, in which recesses 6 for the fastening part 1

are provided.

For further holding the fastening part 1, outwardly facing tabs 7 are provided, which support the retaining ring 4 on the baffle 8 when installing the loudspeaker 2 in the baffle 8. According to the invention, the fastening part 1 now has at least one detent spring 9 for fastening the loudspeaker as well as at least one locking spring 10 for fastening in the baffle.

. From the position shown in Figure 2 is view of the attachment part 1 it can be seen that _it comprises a for attachment of the speaker two latching springs 9, 11 and fixing S in ¹ ö baffle - greater - detent spring are provided. The detent spring 10 for the baffle is shaped in such a way that a sufficiently secure attachment for different thicknesses of the baffle

is guaranteed.

In the embodiment of the invention shown in FIG. 3, the detent springs 9, 10, 11 are designed similarly to the embodiment shown in FIG. 1. Only the tabs provided for fastening the detent spring on the retaining ring 4 are shaped differently. The outward-facing tabs are used to fasten the fastening part to the retaining ring. Corresponding slots are provided in the retaining ring for this purpose. The inwardly facing tabs 13 rest on the edge of the outlet opening of the loudspeaker, so that the edge 14 of the loudspeaker frame, shown in dashed lines, is clamped between the tabs 13 and the locking springs 9, 11 . ■ Ί.
