An in-the-ear hearing aid device is disclosed. The device at least one electro-acoustic transducer, and at least one sensor or at least one active electronic component. The at least one electro-acoustic transducer comprises a capsule enclosing a transducer sound active part and a transducer air volume. The transducer air volume is air volume which is enclosed by said capsule and which is in fluid-connection with said transducer sound active part. At least a portion of said at least one sensor or of said at least one active electronic component is provided within said transducer air volume.

In-the-ear hearing aid device, a hearing aid, and an electro-acoustic transducer

The present disclosure relates to a hearing aid with an RF antenna arranged within the hearing aid's housing, and a loudspeaker positioned in the ear canal of the user. The RF antenna is configured to receive and/or transmit electromagnetic RF signals within a first frequency range enclosing a first frequency of resonance of the RF antenna corresponding to a first wavelength. The hearing aid further comprises one or more electric leads electrically connected to lead one or more electric signals within a second frequency range not overlapping the first frequency range between the loudspeaker in the ear canal of the user and an electronic circuit in the housing, with the one or more electrical leads being decoupled, at a connector end of the one or more electrical leads, by means of one or more decoupling components.

RF antenna and hearing device with RF antenna

The present disclosure provides methods and systems for reducing noise induced in one or more components in a hearing aid. The present disclosure provides methods for reducing noise induced in telecoils.

Noise reduction method and system

A hearing aid includes: a power source; and a switched capacitor DC-DC converter electrically connected to the power source and having an input part configured for receiving charge from the power source at an input voltage of an input voltage range; an output part having multiple output ports, the output part being configured for supplying charge to the multiple output ports for providing multiple predefined output voltages; at least one flying capacitor configured for redistributing charge from the power source to the multiple output ports and/or in between the output ports; and a switching circuitry having a plurality of switches configured for electrically switching the switched capacitor DC-DC converter based on a switching scheme so as to provide the multiple predefined output voltages based on the input voltage.

Hearing device having a power source

The present disclosure relates to an RF antenna adapted to receive and/or transmit electromagnetic RF signals within a first frequency range enclosing a first frequency of resonance of the RF antenna, the RF antenna comprising: an electrically conductive antenna element having a feed for electrically connecting to an RF transmitter and/or an RF receiver; an electronic component adapted to receive and/or provide one or more electric signals from/to an electronic circuit within a second frequency range not overlapping the first frequency range; and one or more electric leads electrically connected to lead the one or more electric signals between the electronic component and the electronic circuit, each of the one or more electric leads being electrically connected to the electronic circuit through a respective inductor adapted to reflect and/or attenuate signals within the first frequency range and pass signals within the second frequency range.

The disclosure presents a method of operating a switched capacitor voltage converter and a switched capacitor voltage converter, where the switched capacitor voltage converter comprises a power source, a bucket capacitance, an output capacitance with output capacitance terminals to be connected to a load and switches. The power source provides an input voltage and the output capacitance provides an output voltage over the output capacitance terminals. The output voltage is different from the input voltage, i.e higher or lower or of opposite polarity. The switches are configured to provide at least two phases, a bucket capacitance charging phase and a bucket capacitance discharging phase. In case of a voltage up-converter in the bucket capacitance charging phase the bucket capacitance is connected to the power source for charging the bucket capacitance while the bucket capacitance is not connected to the output capacitance. In a voltage down-converter in the bucket capacitance charging phase the bucket capacitance and the output capacitance are connected in series with the power source. In a voltage up-converter in the bucket capacitance discharging phase the bucket capacitance is connected in series with the power source for charging the output capacitance. In a voltage down-converter in the bucket capacitance discharging phase the bucket capacitance and the output capacitance are connected in parallel with each other while being disconnected from the power source. Further, a detection circuit is provided that is configured to monitor the output voltage over the output capacitance terminals and to cause switching of at least one of said switches so as to interrupt charging of the output capacitance when output voltage exceeds a predefined reference voltage.
