  • 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.

  • Patent number: 10863292
    Abstract: An elastic damping element provides a vibration-damping mounting of a receiver inside a hearing instrument. The damping element contains a hollow base body, from the inner surface of which a plurality of retaining projections project, and each retaining projection has at its distal end a contact surface for the receiver that will be mounted there. A recess, which is formed in an outer surface of the base body in alignment with the associated retaining projection in order to achieve a reduced material thickness, corresponds with at least one of the retaining projections.

  • Patent number: 10038960
    Abstract: A hearing aid, in particular a behind-the-ear hearing aid, has a housing to be worn behind an ear of a user, and a receiver which, in order to transmit sound to the ear, is connected to a sound tube having a housing-side end on which a plug connector is arranged. The plug connector is connected releasably to the housing. The hearing aid is characterized in that the plug connector contains a holder for the receiver, and the receiver is a component part of the plug connector.

  • Patent number: 8755551
    Abstract: A hearing apparatus has a housing, a receiver in the housing, and a sound conductor through which sound from the receiver is conducted out of the housing. In order to render the device as small as possible, the hearing apparatus has a cover piece which is inserted into the housing in such a way that a sound channel is formed. The sound channel is thereby delimited at the sides by the housing and the cover piece. A special sound-conducting tube can therefore be dispensed with.

  • Patent number: 8644543
    Abstract: With a hearing aid device in a frame configuration, acoustic feedback is avoided with an opened battery charger. To this end, a seal surrounds the frame component in an annular manner, the seal sealing a gap between the frame component and the housing thus providing a more user friendly hearing aid.

  • Patent number: 8644541
    Abstract: A hearing apparatus and in particular a hearing aid are to be optimized as regards the risk of feedback. The hearing apparatus contains a housing, having a first opening and a second opening, and with a frame, in or on which a signal processing component is attached, and which can be inserted into the first opening of the housing as far as an end position. A ramp is disposed in the housing which interacts with the frame such that the frame is also moved perpendicular to the direction of insertion toward the second opening during insertion into the housing along a direction of insertion only in one section as far as the end position, which is less than 30% of the insertion path from the first opening to the end position.

  • Patent number: 8462971
    Abstract: When external receivers are used in hearing devices there is a need to suppress feedback further. An ear mold with a receiver is therefore proposed, having a receiver connector including a first snap-fit element at the sound outlet. An adapter is inserted directly into the ear mold and has a second snap-fit element, which is snapped into the first snap-fit element in a manner such that it can be released. A seal, which surrounds the receiver connector completely, is made of a more elastic material than the receiver connector and the adapter and is fitted between the receiver connector and the adapter. It is thus possible to secure the receiver in the ear mold in an acoustically sealed manner, so that there is less feedback. The seal however also ensures that less dirt reaches the receiver.
