摘要:
Provisions to charge the battery of a hearing apparatus without having to remove the battery from the housing are provided. A hearing apparatus separates charging contacts, which are disposed on the surface of the housing and serve to charge the battery, from the battery and to connect the battery to an amplifier circuit, when the battery is not being charged. Otherwise, when the battery is being charged, the hearing apparatus connects the charging contacts to the battery and separates the battery from the amplifier circuit. This double switching function means that the amplifier circuit is protected from charging power surges and also in the normal operating state of the hearing apparatus electrochemical reactions at the charging contacts are avoided.
摘要:
The operation of appliances in a home network is to be made more user-friendly, for which purpose provision is made for the hearing device remote control unit to be integrated as a component in a network. This would, for example, enable warning signals triggered by the network to be provided in the hearing devices.

The aim is to better suppress background noises during the use of hearing devices. To this end, provision is made to record an electrical or electromagnetic useful signal via a corresponding interface and an interference sound by means of a microphone of the hearing device. The processed useful signal is output from a receiver of the hearing device. A vent is formed when the hearing device is worn in or on the ear, through which vent a sound transmission function from the microphone to the eardrum of the hearing device wearer exists. The interference sound signal of the microphone is filtered as a function of the sound transmission function of the vent such that an interference sound reaching the eardrum through the vent is reduced in its effect on the eardrum by means of a balancing sound, which is generated on the basis of an interference sound signal of the microphone from the receiver. The sound reaching the eardrum through a vent can thus be reduced in its interference effect by means of out-of-phase cancellation.
摘要:
A hearing device that is operated with a rechargeable battery pack has at least one contact element that is fashioned to accept a charging current in electrical connection with an external charging device. The contact element is resiliently mounted at the hearing device and can be pressed onto a charging contact of the external charging device during a charging state under the application of a positive force. The contact element is located in a first position in an operating state or rest state of the hearing device, and is moved into a second position in the charging state.
