Audio device, electronic circuit, and related methods, in particular a method of manufacturing an electronic circuit for an audio device is disclosed, the method comprising providing a circuit board; mounting one or more electronic components including a first electronic component on the circuit board; applying a first insulation layer outside the first electronic component; and applying a first shielding layer outside the first insulation layer.

An assembly is provided which includes a package and a printed circuit board. The package includes a housing bounding a region and an acoustic sensor within the region. The housing includes a base with a first hole. The sensor is configured to generate signals indicative of sound received by the sensor through the first hole. The printed circuit board is in mechanical communication with the base and includes a second hole aligned with the first hole such that sound received by the second hole propagates through the first hole to the sensor. The printed circuit board further includes an electrically conductive layer, at least a portion of which extends across the second hole and is configured to allow the sound to propagate through the second hole and to at least partially shield the region containing the sensor from electromagnetic interference.

Presented herein are techniques for time interleaving the sampling of input signals with the delivery of stimulation signals to a recipient of an implantable electrically-stimulating hearing prosthesis. The input signals, which are received via one or more input channels and sampled by a sound processing unit, are susceptible to electrical feedback from the stimulation signals. As such, in accordance with embodiments presented herein, the sampling of the input signals by the sound processing unit, and the delivery of the stimulation signals to the recipient, are synchronized with one another so as to avoid stimulation-evoked electrical feedback within the input signals.

A wireless charging case for a headset, which case comprises a housing, a charging receiver coil and a rechargeable battery. The rechargeable battery comprises a first battery side extending between a first edge and a second opposite edge and facing the charging receiver coil, a second battery side lying extending from the first edge and a third battery side extending from the second edge. A magnetic shield sheet is arranged between the charging receiver coil and the first battery side. Parts of the second battery side and third battery side are covered by magnetic shield sheet.

The present disclosure relates to a hearing aid having at least two wireless interfaces, where the operation of one wireless risk introducing noise into the at least second wireless interface. The first wireless interface being configured so that it does not, or at least to a limited degree, introduce noise into the second wireless interface.

Method to perform dynamic beamforming to reduce SNR in signals captured by head-wearable apparatus starts with microphones generating acoustic signals. Microphones are coupled to first stem of the apparatus and to second stem of the apparatus. First and second beamformers generate first and second beamformer signals, respectively. Noise suppressor attenuates noise content from the first beamformer signal and the second beamformer signal. Noise content from first beamformer signal are acoustic signals not collocated in second beamformer signal and noise content from second beamformer signal are acoustic signals not collocated in first beamformer signal. Speech enhancer generates clean signal comprising speech content from first noise-suppressed signal and second noise-suppressed signal. Speech content are acoustic signals collocated in first beamformer signal and second beamformer signal.

As described in some examples of this disclosure, a Behind-The-Ear (BTE) hearing instrument comprises processing circuity, a battery that stores energy for use by the processing circuitry, and a housing that contains a receiver configured to output sound. The receiver is positioned within the hearing instrument posterior to the processing circuitry and the power source.

A method and device for compensating for an influence of a magnetic interference source on a measurement of a magnetic field sensor in a device. In the method, a magnetic flux density M.sub.1 measured with the magnetic field sensor at a measured ambient temperature T.sub.k is compensated for with a compensation factor M.sub.interference of the magnetic interference source according to

M=M.sub.1−M.sub.interference,

where

M.sub.interference=M.sub.0+aM.sub.0(T′.sub.k−T.sub.0)

and M.sub.0 is a magnetic reference flux density relative to a reference temperature T.sub.0, a corresponding to a material parameter, which is defined for a used magnet material of the magnetic interference source, and the measured ambient temperature T.sub.k being corrected using a non-linear delay parameter to a temperature of the magnetic interference source T′.sub.k. The method is used for the axis-based compensation of a temperature drift, the material parameter a being determined individually for each Cartesian axis.

A hearing device has a housing in which a receiver is arranged as an electrical component. An antenna arrangement is formed, which has a winding in the form of a coil, which is arranged around the receiver with the interposition of a shielding foil. The shielding foil has a section extending around the receiver and several lugs adjoining it, which project beyond the receiver, the lugs enclosing between them an interspace adjoining the receiver. The shielding foil has in particular two layers, namely a magnetic layer and an electrical shielding layer. By this arrangement an antenna arrangement with high sensitivity is formed and at the same time a shielded partial area is created in the inter-space in which further components can be arranged. Due to the design of the lugs, which are particularly flexible, they can be attached to an inner wall of a housing.

An electronic device may include a housing, a first frame disposed inside the housing and including a first surface, a second frame forming an internal space by being coupled with the first frame, and including a second surface opposed to the first surface, a speaker disposed in the internal space and including at least one voice coil, and a battery disposed on a side of the second frame. The second frame may include at least one frame hole, and a ratio μ/μ0 of a magnetic permeability to a vacuum permeability of at least one of a material of the first frame or a material of the second frame may be equal to or greater than 1000.
