Abstract

A loudspeaker box that is particularly suitable for a hearing aid, includes a cup-like box bottom shell, which delimits a box interior for at least partially receiving a loudspeaker, and a cup-like box cover shell, which, in the intended assembly state of the loudspeaker box, is placed on the box bottom shell overlapping it for a part of its cup height to enclose the box interior and to house the loudspeaker. In the intended assembly state, the box bottom shell and the box top shell form a fluid-tight seal of the box interior in the region of their overlap by the use of a material with increased elasticity relative to the box bottom shell and/or the box cover shell. The box bottom shell and cover shell are reversibly connected to one another in a nondestructively releasable manner.

First claim

The invention claimed is:

1. A loudspeaker box, comprising:
a cup-shaped box bottom shell formed to delimit a box interior for at least partially receiving a loudspeaker; and
a cup-shaped box cover shell, which, in an intended assembly state of the loudspeaker box, is placed on said box bottom shell with an overlap for a part of a cup height thereof, to close the box interior and to house the loudspeaker;
wherein said box bottom shell and said a box top shell, in the intended assembly state, form a fluid-tight enclosure of the box interior by a material at the overlap that has an elasticity which is increased relative to a material of at least one of said box bottom shell or said box cover shell; and
wherein said box bottom shell and said box cover shell are reversibly connected to one another in a nondestructively releasable manner in the intended assembly state.

2. The loudspeaker box according to claim 1 , wherein said box cover shell is formed from the material having the increased elasticity, and is formed with an interference fit with the box bottom shell.

3. The loudspeaker box according to claim 2 , wherein said box cover shell is formed from an elastomer.

4. The loudspeaker box according to claim 1 , wherein said box bottom shell is formed from a plastic having increased rigidity or from a metal.

5. The loudspeaker box according to claim 1 , further comprising elastic mounts for mounting the loudspeaker relative to said box bottom shell and/or said box cover shell in the box interior in the intended assembly state for vibration damping.

6. The loudspeaker box according to claim 1 , further comprising a seal element which, in the intended assembly state, is disposed between said box bottom shell and said box cover shell, at least in a region of the overlap therebetween, and said seal element is formed of the material having the increased elasticity and is configured at least to assist in forming a fluid-tight seal of the box interior.

7. The loudspeaker box according to claim 6 , further comprising elastic mounts for mounting the loudspeaker relative to said box bottom shell and/or said box cover shell in the box interior in the intended assembly state for vibration damping, and wherein said seal element is integrally formed with said mount.

8. The loudspeaker box according to claim 6 , wherein said mount are pyramidal nubs with tips on which the loudspeaker rests in the intended assembly state.

9. The loudspeaker box according to claim 8 , wherein said nubs protrude on the inside from a ring strip forming said seal element and in the intended assembly state protrude from an outside through corresponding passages in said box bottom shell into the box interior.

10. The loudspeaker box according to claim 1 , wherein said box bottom shell or said box cover shell is formed with a sound passage opening, through which a guided emission of airborne sound takes place in an intended operation of the loudspeaker.

11. The loudspeaker box according to claim 1 , configured for incorporation in a hearing aid.

12. A hearing aid, comprising: a loudspeaker box according to claim 1 .
