Each leg of the antenna is provided with a first coupling part releasably engaging a corresponding second coupling part of the hollow housing, and at least one locking part is movable between a locking position in which the first coupling parts are locked to the corresponding second coupling parts and a release position in which the first coupling parts are free to be removed from the corresponding second coupling parts.

A hearing aid system according to sonic examples includes a hearing aid which includes a microphone, amplifier, speaker, and a telecoil. In some examples, the hearing aid may include a battery or a capacitor for storing power wirelessly received from a distance separated wireless power transfer unit. The telecoil may be configured to receive audio signals and couple the audio signals to audio processing circuitry of the hearing aid. The telecoil may be further configured to receive power signals from the base unit and couple the power signals to power supply circuitry of the hearing aid, for example for charging the battery of the hearing aid. Examples of transmitter and receiver coils, and of distance and orientation optimization are described. Examples of wireless charging systems that may be used with hearing aids or other medical assistance devices are described.

A hearing aid electrical contact structure and a hearing aid are provided. The hearing aid electrical contact structure includes: a housing, wherein the housing includes a front section and a rear section connected to each other; the rear section is used for accommodating a battery and at least a part of a flexible circuit board; an outer side surface of the rear section has at least two side holes; a conductive contact sheet is assembled in each of the at least two side holes, and the conductive contact sheet is electrically connected to a pad of the flexible circuit board; an outer surface of the conductive contact sheet realizes a transition with the outer side surface of the rear section. The hearing aid electrical contact structure has a smooth surface without any groove structure or convex structure.

A device including a prosthesis configured with a sound capture system and configured to evoke a hearing percept based on a captured sound captured by the sound capture system, wherein at least a portion of the prosthesis is configured to attach to a head of a recipient such that sound is captured by the sound capture system externally of the recipient at a location below an ear canal of a human.

Described is a human-ear-wearable apparatus having a housing, which contains electronic and auditory components for conveying sound into a human hear. An inflatable mounting system is configured to secure the housing to the human ear. The mounting system includes an elastomeric bladder configured to inflate into a customizable counterpart shape of portions of the user's Concha and Meatus areas of a particular user's ear. A pump, coupled to the housing, is configured to pass air through an opening in the housing to the elastomeric bladder. Inflation of the bladder, via the pump, is controllable by a user to form a customized fit of the mounting system's bladder to the Concha and Meatus areas of the user's ear. One or more speakers may be encased in the elastomeric bladder. For example, a dual-hybrid speaker arrangement is described with a cone speaker and a balanced-armature driver embedded in the bladder.

The present disclosure relates to charging and recharging systems for compact hearing aids, components thereof, and support devices therefor. The charging and recharging systems generally include a light emitting device, such as an aural insert having a light emitting diode, and a photovoltaic cell disposed on an implanted hearing aid. In operation, the light emitting device is positioned in or near the entrance of the ear canal and transmits light energy across the ear canal towards the implanted hearing aid. The photovoltaic cell receives the light energy and converts the light energy into stored electricity to power the hearing aid.

A power supply system used in a hearing assistance device including a housing including a battery storage region, a first removable battery holder including a first latch having a first latch configuration and configured to fit within the battery storage region and to hold at least one battery, and a second removable battery holder including a second latch having a second latch configuration that is different that the first latch configuration and configured to fit within the battery storage region and to hold at least one battery.

A facility is provided for the wireless resonant charging of rechargeable hearing instruments. The hearing instrument is freely positionable in a charging device for charging purposes. The charging device for the wireless charging has a transmit antenna arrangement, a transmit amplifier for actuating the transmit antenna arrangement and a charging space. The transmit antenna arrangement has two feeding points, which are spatially arranged in relation to the charging space such that a circularly polarized electromagnetic field can thus be generated in the charging space. The transmit amplifier actuates the antennas accordingly to generate a circularly polarized electromagnetic field in the charging space. In the process a coil arrangement generates a circularly polarized HF field. A good resonant coupling, even with a tilted hearing instrument, is possible, in other words with an undetermined and unpredictable orientation and position of the receive coil of the hearing instrument.

Examples of canal hearing devices including a lateral section having a frequency shaping sound port system are disclosed. A lateral section includes an elongate sound channel for receiving an incoming sound and producing a frequency-shaped sound output. The hearing device includes a microphone, a speaker for transmitting sound to the eardrum, and a sound port to receive the frequency-shaped sound output from the elongate sound channel and provide a pathway for the frequency-shaped sound output to reach the microphone.

An external device of a prosthesis, including an electronics component, which can be a sound processor of a hearing prosthesis, and a power component, which can be a battery, the power component being removably attached to the electronics component, wherein the BTE device is configured with electrostatic discharge protection between the electronics component and the power component.
