  • Publication number: 20130004005
    Abstract: 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.

  • Publication number: 20120328139
    Abstract: A behind-the-ear hearing device has a housing with a plug-in connector on a sidewall of the housing for connecting to an earpiece tube or sound tube. The lateral arrangement of the plug-in connector moves the plug-in connector away from the exposed position on the front end face of the housing. This enables the front end face, which is generally visible, to be made smaller. Advantageously, at least two microphones are provided, with one microphone position in the vicinity of the front end face of the housing. The front microphone position is thus moved farther away from a position that may possibly be covered by the pinna, and the rear microphone position can also be moved farther toward the front. The microphone positions are thus approximately horizontal, which promotes the spatial resolution of the detected surrounding sound (directionality) by the signal processing of the hearing aid.

  • Publication number: 20090267678
    Abstract: An integrated circuit includes: a terminal for outputting data, a driver for providing the data to the terminal, and a switch for selectively connecting/disconnecting the driver to the terminal. The disconnection of the driver reduces the capacitive load on the connection between the terminal and driver, thus reducing limitations on data rate from factors such as data reflections that reduce signal quality. Selective connection/disconnection allows the driver to be reconnected to the terminal only when needed.
