A magnetic switch assembly for hearing devices designed for remote activation by the user is highly miniaturized with a self-contained latching mechanism. The switch is activated and deactivated by the user via a hand-held magnet placed in proximity to the hearing device. The switch assembly includes a miniature reed switch and a miniature latching magnet affixed directly to one of the reeds or the associated lead wire. Direct attachment minimizes the air gap between the latching magnet and a reed thus enabling latching with only an extremely small magnet. The latching magnet produces a magnetic field of adequate strength to hold the reeds together in electrical contact after the air gap between the reeds is closed by the user's placement of the external hand-held magnet in proximity thereto. But the latching magnet's field is of inadequate strength for unaided closure of the air gap between the reeds. Consequently, once the reeds are closed the latching magnet prevents separation thereof until the reeds are exposed to an external magnetic field of opposite polarity and sufficient strength to overcome the field produced by the latching magnet.

Supplying energy into a hearing apparatus in order to charge its rechargeable battery is to be carried out by way of components, which take up as little space as possible. Components, which are mostly already present, are thus used for the energy supply. Energy is inductively injected into the coil of a receiver, into a data transmission coil or a telephone coil for instance. Alternatively, acoustic energy can also be injected via the receiver or microphone and converted there into electrical energy. Special components need then not be provided for the energy supply process.

The system bus can support more peripheral devices than there are available time slots, and supports interrupt polling and servicing. In addition, peripheral devices that include an electro-mechanical or electro-acoustical component connected to the system bus can also communicate directly to each other without using the system bus. The system bus can be implemented in low voltage, low power devices, including listening devices such as hearing instruments and headsets, portable telephones, and personal digital assistants.

A method for frequency transposition in a communication device Or a hearing device, respectively, is disclosed by transforming an acoustical signal into an electrical signal (s) and by transforming the electrical signal from time domain into frequency domain to obtain a spectrum (S). A frequency transposition is being applied to the spectrum (S) in order to obtain a transposed spectrum (S′), whereby the frequency transposition is being defined by a nonlinear frequency transposition function. Thereby, it is possible to transpose lower frequencies almost linearly, while higher frequencies are transposed more strongly. As a result thereof, harmonic relationships are not distorted in the lower frequency range, and at the same time, higher frequencies can be moved to a lower frequency range, namely to an audible frequency range of the hearing impaired person. The transposition scheme can be applied to the complete signal spectrum without the need for switching between non-transposition and transposition processing for different parts of the signal. Therefore, no artifacts due to switching are encountered. A higher transmission quality is obtained because more information is taken into account for the transmission.
