Patent number: 11956598Abstract: 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.Type: GrantFiled: January 11, 2021Date of Patent: April 9, 2024Assignee: Sivantos Pte. Ltd.Inventors: Kevin Bayer, Stefanie Beyfuss, Holger Kral, Hartmut Ritter

Patent number: 11729558Abstract: A hearing device includes a housing elongated along a longitudinal axis, having an oval cross section, and configured to house electrical components. A loudspeaker disposed outside the housing in an intended wearing state of the hearing device is interconnected with at least a part of the electrical components. A plug connector is connected to the loudspeaker and carries at least six contact elements for interconnecting the loudspeaker with corresponding electrical components. A plug connector receptacle for receiving the plug connector interconnects the contact elements. The plug connector receptacle is disposed in a surface of the housing oriented toward a lower side in the intended wearing state. The plug connector and the plug connector receptacle define a plug-in direction extending from a front side to a rear side in the intended wearing state.Type: GrantFiled: April 29, 2021Date of Patent: August 15, 2023Assignee: Sivantos Pte. Ltd.Inventors: Muhammad Shahid Bin Shith, Thai Wee Ang, Lit Song Glen Ding, Holger Kral

Patent number: 10805743Abstract: A connector for a hearing instrument, in particular a receiver-in-canal behind-the-ear hearing aid, is small and visually inconspicuous. The connector should be as invisible as possible on the hearing instrument as it is worn, and the connector allows a microphone arrangement favorable for directionality and sound pick-up. The connector is disposed on an earpiece tube, which defines a longitudinal direction at the connector. The connector is connected by insertion into a connector receptacle of a hearing instrument transversely to the longitudinal direction. The hearing instrument has a laterally arranged connector receptacle, into which a connector is inserted transversely to the longitudinal direction. Because of the transverse insertion, the connector can be arranged laterally on the housing and because of the lateral placement, the front end face of the housing is smaller and the housing is overall flatter.Type: GrantFiled: September 10, 2019Date of Patent: October 13, 2020Assignee: Sivantos Pte.

Patent number: 10667066Abstract: A hearing device contains an electronic frame for holding electronic components. The hearing device has first and second resilient contacts. The resilient contacts are fastened to the electronic frame, and the resilient contacts reversibly electrically contact an electronic component using contact surfaces of a double-pole battery. The hearing device contains a rechargeable battery module that contains a rechargeable battery and an electronic convertor. The rechargeable battery module is connected in an articulated manner to the electronic frame so as to be able to move and contains connecting contacts that correspond to the resilient contacts. A kit is provided for the hearing device and the kit has a battery compartment door for reversibly holding the double-pole battery. The battery compartment door is connected to pivot on the electronic frame such that as the battery compartment door is pivoted into a closed position the contact surfaces of the double-pole battery are contacted.Type: GrantFiled: December 10, 2018Date of Patent: May 26, 2020Assignee: Sivantos Pte.

Patent number: 10595140Abstract: An electronics frame for a hearing device serves to hold electronic components and has a contact carrier. The carrier in turn has a first line connector, a second line connector, and a third line connector. The three line connectors serve to electrically contact at least one of the electronic components with a first connection contact, a second connection contact which is at a potential that is different from the first connection contact, and with a third connection contact of a storage battery module which has a rechargeable battery. The contact carrier moreover has a first insertion slot for receiving a first contact arm which serves to electrically contact a contact of a two-pole battery. A kit for the hearing device contains, in addition to the hearing device with the electronics frame, the storage battery module and at least the first contact arm for subsequent mounting on the contact carrier.Type: GrantFiled: December 10, 2018Date of Patent: March 17, 2020Assignee: Sivantos Pte.

Patent number: 10425752Abstract: A hearing aid contains an ear insert which has an earpiece and a connection part which is connected to a receiver. The earpiece and the connection part each has a plug connector and are connected together by the plug connectors. One plug connector is a connection piece which extends in an axial direction along a longitudinal axis and has a thickened portion in the radial direction, and the other plug connector engages behind the thickened portion in order to axially fix the earpiece to the connection part. The thickened portion has an undercut and forms a retaining surface which runs into the thickened portion in a wedged manner. In this manner, the earpiece is attached to the connection part in a particularly secured manner.Type: GrantFiled: November 27, 2017Date of Patent: September 24, 2019Assignee: Sivantos Pte.

Patent number: 9654886Abstract: A connector-based link is suited to various signals and media for connecting a tube with a hearing instrument, which ensures a reliable mechanical hold, good connection and high tightness and in the process is easy to handle. This is achieved by a connector for a hearing instrument system including a housing which contains a number of connections, and a tube which contains a number of lines, which is embodied to detachably connect a number of lines of the tube to a number of connections of the housing, wherein the connections of the connector contain different spatial orientations. The fact that the connections each have a different spatial orientation brings about a mutual decoupling. As a result, the demands on dimensional stability of the various connections are advantageously reduced since the different connections are not closed in a shared, identical end position.Type: GrantFiled: June 27, 2013Date of Patent: May 16, 2017Assignee: Sivantos Pte. Ltd.Inventors: Joachim Roland Barth, Holger Kral, Joseph Sauer
