Definitions
- the invention is concerned with the improvement of cone speakers, in particular with the improvement of the membrane stability.
- the disadvantage just discussed can be remedied by making the membrane from an extremely rigid material.
- the membrane from an extremely rigid material.
- there are limits to this possibility of improving the rigidity of the membrane since from a certain rigidity materials and wall thicknesses are required which are no longer tolerable under the criterion of the lightness of the membrane.
- the invention is therefore based on the object of creating a cone loudspeaker which is distinguished, on the one hand, by a light membrane construction and, on the other hand, has an extraordinarily high rigidity and freedom from partial vibrations of the membrane.
- a conical stabilizing element is arranged between the underside of the membrane and the magnetic pot, the end of which is connected to the larger diameter of the underside of the membrane and the other end is connected to the outer surface of the voice coil bobbin.
- the cone loudspeaker shown in FIG. 1 is essentially formed by magnet system 10 and the cone-shaped loudspeaker basket 11 connected to it.
- the conical membrane 12 is inserted into the loudspeaker basket 11.
- the membrane 12 is connected to the upper edge of the speaker basket 11 by means of a circumferential bead 13.
- the other end of the membrane 12 is connected to the tubular voice coil former 14 with the adhesive seam K1.
- the voice coil support 14 is connected with its outer surface 17 via an accordion-shaped centering membrane 18 to the speaker basket 11.
- the connection between the voice coil former 14 and the centering membrane 18 is through the adhesive seam K2 realized.
- one end of the stabilizing element 19 is also connected to the voice coil former 14.
- the other end of the stabilizing element 19 is glued to the underside 20 of the membrane 12 by means of the further adhesive seam K3.
- the geometry of the stabilizing element 19 is dimensioned such that the end which is connected to the membrane 12 has a diameter such that this end supports the membrane at a location at which the first radial vibration mode occurs. Compliance with the upper diameter of the stabilizing element 19 just discussed has the effect that the area of the radiation surface of the membrane 12 is enlarged, since the support of the membrane 12 at this location greatly reduces partial vibrations.
- the loudspeaker shown in FIG. 2 differs from that shown in FIG. 1 only in that the stabilizing element 19 in FIG. 2 has a modified shape.
- This modified shape consists in that the membrane 12 is connected on its underside 20 in the area between the adhesive seams K1 and K3 by the reinforcing element 21 to the stabilizing element 19 via the adhesive seams K4 and K5.
- the stabilizing element 19 and the reinforcing element 21 can also be formed in one piece, for example as a film pulling part. In this case, only one adhesive seam is required, which connects the reinforcing element 21 to the underside 20 of the membrane 12.
