Embodiment Construction

[0128] More specifically, image 3 A typical example of a plurality of shielding or protective layers stacked in the vicinity of an acoustic element 10 according to the prior art is shown, wherein between the magnetic field source 10 and the device housing 11 a protective monofilament fabric 12 is arranged (for providing protection against solid particles and liquids) and perforated plates of ferromagnetic material 13.

[0129] From bottom to top, from the acoustic element 10 to the plastic housing 11 , the layers are combined with each other, usually by means of a bi-adhesive material and a gasket 14 .

[0130] Alternatively, the ferromagnetic material porous plate 13 can be fixed by a small bracket made of plastic or metal material.

[0131] According to the present invention, Figure 4 The exemplary embodiment of the stack-up shown includes only a multi-layer element 100 assembled by double-sided adhesive material and / or gasket 114 between the source of the magnetic field...
