Abstract

A vehicle door, comprising an inner door panel and an outer door panel with an inner surface facing the inner door panel, is provided. A loudspeaker which is arranged on the inner door panel, is spaced apart from the outer door panel and is intended for generating acoustic sound waves. A sound-guiding element which is designed to deflect sound waves radiated in the direction of the outer door panel by the loudspeaker and to guide said sound waves into a wet chamber of the vehicle door, which wet chamber is formed between the inner door panel and the outer door panel, and/or into a dry chamber of the vehicle door, which dry chamber is formed on a side of the inner door panel that faces away from the outer door panel.

First claim

The invention claimed is:

1. A vehicle door, comprising
an inner door panel,
an outer door panel with an inner surface facing the inner door panel
a door module comprising a carrier element configured to carry functional components of the vehicle door and being arranged on the inner door panel,
a loudspeaker on the carrier element of the door module, the loudspeaker being spaced apart from the outer door panel and being configured to generate acoustic sound waves, and
a sound-guiding element which is designed to deflect sound waves radiated in the direction of the outer door panel by the loudspeaker and to guide said sound waves into at least one of a wet chamber of the vehicle door, which wet chamber is formed between the inner door panel and the outer door panel, and into a dry chamber of the vehicle door, which dry chamber is formed on a side of the inner door panel that faces away from the outer door panel,
wherein the sound-guiding element is fastened via braces to the door module, and wherein slats for reflecting sound waves reflected at the sound-guiding element are arranged on the braces, the slats extending in parallel and being spaced from to each other.

2. The vehicle door as claimed in claim 1 , wherein the sound-guiding element is formed by a diffuser which is arranged between the loudspeaker and the outer door panel and is designed to reflect sound waves radiated in the direction of the outer door panel by the loudspeaker in such a manner that they do not strike in a directly radiated manner perpendicularly against the inner surface of the outer door panel.

3. The vehicle door as claimed in claim 2 , wherein the sound-guiding element has a reflection surface which is directed at an oblique angle to a main plane of extent along which the outer door panel extends.

4. The vehicle door as claimed in claim 2 , wherein the sound-guiding element has a body in the form of a rhombus or a cone.

5. The vehicle door as claimed in claim 4 , wherein the body has a tip facing the loudspeaker.

6. The vehicle door as claimed in claim 5 , wherein the tip is arranged concentrically with respect to a center axis of the loudspeaker, the center axis pointing through the center of gravity of the loudspeaker and running along a main direction of radiation of the loudspeaker.

7. A vehicle door, comprising
an inner door panel,
an outer door panel with an inner surface facing the inner door panel,
a door module comprising a carrier element configured to carry functional components of the vehicle door and being arranged on the inner door panel,
a loudspeaker on the carrier element of the door module, the loudspeaker being spaced apart from the outer door panel and being configured to generate acoustic sound waves, and
a sound-guiding element which is designed to deflect sound waves radiated in the direction of the outer door panel by the loudspeaker and to guide said sound waves into at least one of a wet chamber of the vehicle door, which wet chamber is formed between the inner door panel and the outer door panel, and into a dry chamber of the vehicle door, which dry chamber is formed on a side of the inner door panel that faces away from the outer door panel,
wherein the sound-guiding element has a number of slats which are directed at an oblique angle to a main plane of extent along which the outer door panel extends, the slats extending in parallel and being spaced from each other.

8. The vehicle door as claimed in claim 7 , wherein the slats are formed in a reflecting manner on an inner surface, which faces the loudspeaker, in order to reflect sound waves radiated in the direction of the outer door panel from the loudspeaker and, on an outer surface facing away from the loudspeaker, bear an absorbing layer for absorbing sound waves.

9. The vehicle door as claimed in claim 7 , wherein the slats are arranged with respect to one another in such a manner that sound waves reflected at the inner surface of a slat strike against the outer surface of an adjacent slat.

10. The vehicle door as claimed in claim 8 , wherein the absorbing layer is configured for absorbing sound waves within a predetermined frequency range.

11. The vehicle door as claimed in claim 7 , wherein
the sound-guiding element is fastened to at least one of the door module,
the outer door panel and the inner door panel.

12. The vehicle door as claimed in claim 7 , wherein the sound-guiding element has a crash pad designed to absorb crash forces, or is connected to a crash pad.

13. The vehicle door as claimed in claim 2 , wherein the sound-guiding element is filled with an acoustically damping additional material or is connected to such an additional material.

14. A vehicle door, comprising
an inner door panel,
an outer door panel with an inner surface facing the inner door panel,
a door module comprising a carrier element configured to carry functional components of the vehicle door and being arranged on the inner door panel,
a loudspeaker on the carrier element of the door module, the loudspeaker being spaced apart from the outer door panel and being configured to generate acoustic sound waves, and
a sound-guiding element which is designed to deflect sound waves radiated in the direction of the outer door panel by the loudspeaker and to guide said sound waves into at least one of a wet chamber of the vehicle door, which wet chamber is formed between the inner door panel and the outer door panel, and into a dry chamber of the vehicle door, which dry chamber is formed on a side of the inner door panel that faces away from the outer door panel,
wherein the sound-guiding element forms a guide channel on the door module for guiding sound waves away from the loudspeaker, the guide channel extending from the loudspeaker along the door module towards an opening formed on the door module to pass sound waves to at least one of the wet chamber and the dry chamber.

15. The vehicle door as claimed in claim 14 , wherein slats for guiding sound waves are arranged in the region of the opening.

16. The vehicle door as claimed in claim 15 , wherein an acoustically damping filler is arranged on the slats.

17. The vehicle door as claimed in claim 14 , wherein the guide channel is at least partially filled with a filler for the frequency-selective damping of sound waves.
