A hearing instrument charger device for charging an individually shaped hearing instrument, includes: a charger casing; a charger power supply within the charger casing; a first charger coil connected to the charger power supply; charger electronics for controlling charging of the hearing instrument; and a holder configured for receiving the hearing instrument, the holder located within the charger casing; wherein the holder for the hearing instrument has a shape that is specific for the individually shaped hearing instrument, such that when the individually shaped hearing instrument is received in the holder, a second charger coil of the individually shaped hearing instrument is in an operative position for receiving charging power from the first charger coil of the hearing instrument charger device.

Hearing instrument charger device and system, and a method of manufacturing a holder therefor

A method of configuring a custom insert of a charger, wherein the custom insert is for aligning a first charging element of a hearing device and a transmitter charging element of a charger, includes: obtaining a digital three-dimensional hearing device model comprising a representation of the first charging element; obtaining a digital three-dimensional charger model comprising a representation of the transmitter charging element; obtaining a digital three-dimensional insert model; obtaining a digital cavity representing a cavity in the custom insert; and creating a custom digital three-dimensional insert model based on the digital cavity and the digital three-dimensional insert model, such that the representation of the first charging element in the digital three-dimensional hearing device model and the representation of the transmitter charging element in the three-dimensional charger model, are aligned.

Alignment between charging elements of a hearing device and a charger

A method of manufacturing a charger insert part of a hearing instrument charger device comprising a charger casing having a receiving portion, and a first charger element, includes: obtaining a first virtual model of the rechargeable hearing instrument shaped or to be shaped to at least partly conform to a shape of a portion of an ear canal of a user, wherein the first virtual model comprises an allocated position for a second charger element; obtaining a second virtual model of the charger insert part for manufacturing the charger insert part, such that when the charger insert part is placed in the receiving portion, the first charger element will be in a relation with the second charger element; and shaping, by a manufacturing process, the charger insert part based on the second virtual model, the second virtual model being based on the first virtual model.

The disclosure relates to a hearing aid for placement in an ear canal, the hearing aid having a proximal end and a distal end, the proximal end is inserted into the ear canal to face the tympanic membrane, the distal end is opposite. The hearing aid comprises a shell customized for the ear canal. The shell comprises an inner space configured for at least partly receiving a rechargeable battery, a charging arrangement, at least one microphone arrangement, and an integrated circuit. The hearing aid comprises a faceplate comprising an upper face and a lower face, the upper face being exposed at the distal end when the shell is placed in the user's ear canal. The faceplate is configured for closing the inner space, wherein the IC is arranged between the faceplate and the proximal end.

Hearing aid for placement in a user's ear canal

A hearing aid for placement in an ear canal of a user, includes: a shell; a faceplate comprising an upper face, and a lower face, and a circumference, the upper face being exposed when the shell is placed in an ear of the user; a coil arranged at the faceplate; and a button arrangement comprising a plunger configured to control an integrated circuit arranged below the coil, the coil comprising one or more windings, the one or more windings being circumferential of an inner cavity of the coil with respect to a center or longitudinal axis of the coil, the button arrangement being configured such that the plunger in at least one position extends through the inner cavity of the coil for engaging the integrated circuit.

A button structure for a hearing device, includes: a first microphone, the first microphone being configured to receive sound via a first microphone input; an elastic member comprising a first part and a second part, the first part comprising a user interface surface, the second part comprising a first opening, the first opening being aligned with the first microphone input; a switch component, wherein the user interface surface is configured to be operated by a user to activate the switch component; and an outer shielding comprising a shield opening and a second opening, wherein at least a portion of the first part of the elastic member extends through the shield opening, wherein the second opening of the outer shield is aligned with the first opening of the second part of the elastic member, and wherein the outer shielding is in contact with the elastic member to create a seal.

Compact, watertight and acoustically-tight button structure

A method of configuring a custom insert of a charger, wherein the custom insert is for aligning a receiver charging element of a hearing device and a transmitter charging element of a charger, includes: obtaining a digital three-dimensional hearing device model comprising a representation of the receiver charging element, wherein the digital three-dimensional hearing device model is based on a digital scan of an ear; obtaining a digital three-dimensional charger model comprising a representation of the transmitter charging element; obtaining a generic digital three-dimensional insert model; obtaining a digital cavity representing a cavity in the custom insert; and creating a custom digital three-dimensional insert model based on the digital cavity and the generic digital three-dimensional insert model, such that the representation of the receiver charging element in the digital three-dimensional hearing device model and the representation of the transmitter charging element in the three-dimensional charger model, are aligned.
