A top case for a motor vehicle, in particular a motorcycle or a motorcycle-type motor vehicle, includes an integrated loudspeaker arrangement with a loudspeaker casing and at least one loudspeaker that is connected to the loudspeaker casing. The top case at least partially forms the loudspeaker casing. The loudspeaker casing includes a horn-shaped duct that is connected in an air-conducting manner to a rear side of the loudspeaker.

First claim

What is claimed is:

1. A top case for a motor vehicle, comprising:
an integrated loudspeaker arrangement having a loudspeaker housing and at least one loudspeaker that is connected to the loudspeaker housing, wherein
the top case at least in portions forms the loudspeaker housing, and
the loudspeaker housing has a horn-shaped duct separate from a luggage-receiving portion of the top case that, in an air-conducting manner, is connected to a rear side of the loudspeaker.

2. The top case as claimed in claim 1 , wherein
the horn-shaped duct comprises at least one tubular portion and one horn portion that is widened to an exit opening of the horn-shaped duct.

3. The top case as claimed in claim 2 , wherein
at least the tubular portion of the horn-shaped duct is aligned so as to be substantially parallel with a front side of the top case.

4. The top case as claimed in claim 2 , wherein
the loudspeaker is disposed in a region of a first side of the top case, and
the exit opening of the horn-shaped duct is disposed in a region of a second side of the top case that is disposed so as to be opposite the first side.

5. The top case as claimed in claim 1 , wherein
the loudspeaker housing comprises one pressure chamber.

6. The top case as claimed in claim 1 , wherein
the loudspeaker housing at least in portions is formed by an inner shell and by an outer shell that is connected to the inner shell.

7. The top case as claimed in claim 6 , wherein
the inner shell is integrally connected to a lid element or a base element of the top case.

8. The top case as claimed in claim 6 , wherein
the outer shell comprises at least one integrated hinge part which is configured for connecting in a rotatable manner to a hinge counterpart of a base element or a lid element of the top case.

9. The top case as claimed in claim 6 , further comprising:
a backrest arrangement for a vehicle user, wherein
the backrest arrangement covers the outer shell at least in portions or completely.

10. The top case as claimed in claim 6 , wherein
one or both of the inner shell and the outer shell are injection molded shells.

11. The top case as claimed in claim 1 , wherein
the loudspeaker is a low-range loudspeaker.

12. The top case as claimed in claim 11 , wherein
