speaker unit

The invention relates to a loudspeaker unit according to the preamble of claim 1.

A loudspeaker unit of this type is known from U.S. Pat. No. 3,575,370.

This is solved according to the invention according to the feature of claim 1. Preferred embodiments of the invention will become apparent from the subclaims.

EP-0 024 461 discloses a loudspeaker unit in which a loudspeaker tincture is fastened between two parts which are fastened to one another by a groove connection. However, the speaker basket is not attached directly to the frame by a groove connection and does not have any element for a shaped groove connection. U.S. Pat. No. 4,424,881 discloses a loudspeaker unit in which a cover is attached to the base by means of a grooved connection to allow the cover to be replaced. However, this does not involve attaching the speaker to the frame to form a speaker unit.

According to the invention, a simple installation of a loudspeaker basket in a frame intended therefor is provided.

For a better understanding of the invention, an example is shown below with reference to the drawings, in which Fig. 1 shows a loudspeaker basket, Fig. 2 shows a loudspeaker unit with mounting points on the sides, Fig. 3 shows a loudspeaker unit with vertical mounting points, Fig. 4 shows a loudspeaker unit shows a top view of the speaker unit.

Figure 1 shows a loudspeaker basket 7 mounted laterally or on the front of the frame. For lateral installation, it has areas 5 and 6. The areas 5 are formed by conical projections opening onto the edge of the loudspeaker basket 2 82582 7. The areas 6 of the loudspeaker basket 7 consist of longitudinal concave material thinnings arranged in the vicinity of the areas 5. In order to mount the loudspeaker basket 7 on its front side, the areas 9 and the movable projection 8 are arranged in the frame. The area 9 is an extension of the material formed on the second front side of the loudspeaker basket 7. It is in the shape of a rectangular tongue. Opposite this area 9 is a movable protrusion 8 arranged on the second front side of the loudspeaker basket 7, which is U-shaped and against which the first crotch turned against the cradle 7 is connected to the loudspeaker basket 7. This first crotch also has a support 13. is formed longer, there is a wedge-shaped stop 14, the tip of which is located at the end of the crotch and the wider surface of which is located at the height of the speaker basket.

Figure 2 shows a speaker unit in which the attachment point of the frame 3 is locked to the side edges of the speaker basket 7. In this case, the frame 3 has movable areas 2, the so-called Snap-In, and the fastening areas 1. The areas 1 of the frame 3 fasten conically to the projections 5 opening towards the frame. When the loudspeaker basket 7 is pressed into the frame 3, the loudspeaker carcass 7 snaps into the areas 6.

Thus, a strong connection between the speaker basket 7 and the frame 3 is provided.

3 shows the speaker unit, wherein the front side of the closed heating element to connect the speaker body and the frame 11 to each other. The tongue-like extension 9 of the loudspeaker basket 7 engages in an opening 10 in the front side of the loudspeaker frame 11. The opposite front side also has a similar opening 10. When the loudspeaker basket 7 is pressed into the frame 11, a movable protrusion 8 engages the widened surface 14 The frame 11 is constructed in such a way that the installation of the loudspeaker basket 7 in the frame 11 is facilitated via the lateral guide strips 15. The same applies to the frame 3 with the guide strips 12.

Figure 4 is a side view of the speaker. The loudspeaker consists of a magnet system 15, a basket 16, an upwardly edging edge 17 il 3 82582 and a snap-in device 8, 9. A seal 18 is located on the radiating surface of the loudspeaker.

Figure 5 shows the speaker from above. As can be assumed from Figure 4, the seal 18 extends over the edge 17 of the speaker. Thus, compression of the speaker into the cover frame is provided.

Claims (5)
