A battery module for a hearing device is configured for an inductive resonance charging method. The battery module includes a secondary cell and a blocking sleeve that encloses the secondary cell to shield the secondary cell against a magnetic field. A jacket formed from permeable material is arranged on the outside of the blocking sleeve. An induction coil, which is arranged on the outside of the jacket, is configured to receive energy inductively. The induction coil and the jacket form a receiving antenna for receiving energy. The induction coil is arranged such that a coil axis of the induction coil is oriented radially with respect to the secondary cell.

Battery module and hearing device

A battery module for a hearing device is configured for inductive resonance charging. The battery module has a secondary cell, a blocking sleeve that encloses the secondary cell and shields the secondary cell against a magnetic field, a jacket formed from permeable material outside the blocking sleeve, and an induction coil outside the jacket for receiving energy inductively. The induction coil and the jacket form a receiving antenna for receiving the energy. The material and/or the geometric structure of the blocking sleeve, the jacket made of permeable material, and/or the induction coil is/are additionally selected in such a way that the battery module, in particular the induction coil, has a quality factor of at least 35 for receiving energy at a predetermined value of a charging frequency that is employed by a charging device that generates a magnetic alternating field.

A method for charging a hearing device uses a charging unit configured for wireless charging. A query signal is emitted wirelessly by a transmitter of the charging unit. Upon receipt of the query signal a first response signal is sent to the charging unit by a response unit of the hearing device. Upon the receipt of the first response signal the charging unit begins a charging operation for the hearing device, by wirelessly emitting a continuous energy signal. A hearing device system, a hearing device and a charging unit are also provided.

A system for transmitting digitized samples of analog signals while concealing unrecoverable digitized samples of analog signals to maintain a level of fidelity in reproducing the analog signals. The digitized samples of the analog signals are burst transmitted such that the probability of interference with the transmission and thus corruption of the digitized samples of the analog signals is minimized. The digitized samples are received without synchronizing a receiving clock with a transmitting clock to capture the digitized samples of the analog signals. The digitized samples are converted from various sampling rates to digitized samples of the analog signals having a rate. Any large groups of digitized samples that are in error or corrupted in transmission are softly muted to avoid annoying clicks. Any long term difference between a transmit clock and a receive clock is tracked and the digitized samples are interpolated or decimated to eliminate any underrun or overrun of the digitized samples.
