  • Patent number: 11956598
    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.
