Abstract

A loudspeaker grille comprises a carrier element, which comprises a plurality of openings through a front surface, and a cover element to be attached to the front surface, which comprises a plurality of openings corresponding to the openings of the carrier element. The cover element is attached to the carrier front surface, wherein the cover element covers at least part of the front surface of the carrier element, and wherein the openings of the carrier element and the cover element are aligned with each other. The cover element is made of a flexible organic material, in particular a compound material with an organic outer surface layer, such as cork-leather.

First claim

What is claimed is:

1. A loudspeaker cover, comprising:
a carrier element comprising a front surface; and
a cover element with a surface made of an organic material, the cover element being attached to and covers at least partly the front surface of the carrier element,
wherein the carrier element and the cover element comprise a plurality of aligned openings.

2. The loudspeaker cover of claim 1 , wherein the cover element is made of a flexible organic material comprising a compound material with an organic surface.

3. The loudspeaker cover of claim 1 , wherein the cover element has a cork surface or a cork-leather surface.

4. The loudspeaker cover of claim 1 , wherein the loudspeaker cover is integrally formed in an interior trim of a vehicle.

5. The loudspeaker cover of claim 4 , wherein the interior trim of the vehicle is a vehicle door trim.

6. The loudspeaker cover of claim 1 , wherein the plurality of aligned openings in the carrier element and the cover element have substantially the same dimensions.

7. The loudspeaker cover of claim 1 , wherein the cover element extends at least partly around a side surface of the carrier element and is fixed at least partly onto the side surface of the carrier element.

8. The loudspeaker cover of claim 7 , wherein the cover element extends at least partly to a back side of the carrier element.

9. The loudspeaker cover of claim 1 , wherein in an active area defined by outer edges of outer openings of the plurality of aligned openings arranged in a group, an open area of the plurality of aligned openings are greater than 30% of the active area.

10. The loudspeaker cover of claim 1 , wherein:
the plurality of aligned openings are longitudinal openings; and
longitudinal axes of the plurality of aligned openings are aligned to each other.

11. The loudspeaker cover of claim 1 , wherein:
a backside of the carrier element includes a plurality of ribs protruding from a back surface of the carrier element; and
