Abstract

A loudspeaker arrangement is disclosed that comprises a hollow box-like enclosure having rigid walls in which a loudspeaker opening and a vent hole are formed; a loudspeaker which is arranged in or at the loudspeaker opening and sealingly secured to the enclosure; and a protective panel which is arranged in or at the vent hole and sealingly secured to the enclosure, wherein the panel comprises at least one gas-permeable and liquid-impermeable membrane.

Claims

1. A loudspeaker arrangement comprising:

an enclosure having rigid walls in which a loudspeaker opening and a vent hole are formed;

a loudspeaker which is arranged in or at the loudspeaker opening and sealingly secured to the enclosure; and

a protective panel which is arranged in or at the vent hole and sealingly secured to the enclosure, the panel comprises at least one gas-permeable and liquid-impermeable membrane.

2. The loudspeaker arrangement of claim 1, in which the membrane allows flow of gas through the membrane at a limited rate which is such that pressure equalization between the hollow interior and the ambience of the enclosure requires at least 1 second.

3. The loudspeaker arrangement of claim 2, in which the membrane allows flow of gas through the membrane at a limited rate which is such that pressure equalization between the hollow interior and the ambience of the enclosure requires at least 1 minute.

4. The loudspeaker arrangement of claim 1, in which the membrane is sealingly secured to the enclosure using a carrier which is sealingly secured to both the membrane and the enclosure.

5. The loudspeaker arrangement of claim 1, in which the membrane comprises a porous material.

6. The loudspeaker arrangement of claim 5, in which the porous material comprises a hydrophobic material.

7. The loudspeaker arrangement of claim 6, in which the hydrophobic material is Polytetrafiuoroethylene.

8. The loudspeaker arrangement of claim 7, in which the hydrophobic material is expanded Polytetrafiuoroethylene.

9. The loudspeaker arrangement of claim 8, in which the panel is a solitary membrane.

10. The loudspeaker arrangement of claim 1, in which the membrane comprises at least two sheet layers.

11. The loudspeaker arrangement of claim 10, in which the membrane comprises laminated sheet layers.

12. The loudspeaker arrangement of claim 10, in which one of the layers is a gas-permeable substrate or support layer.

13. The loudspeaker arrangement of claim 12, in which the gas-permeable substrate or support layer is selected from a group consisting of woven material, nonwoven material, and mesh material.

14. The loudspeaker arrangement of claim 10, in which at least two of the sheet layers are liquid-impermeable.
