An electronic device including a coin-cell battery is provided. The electronic device further includes a housing, a battery comprising a first surface, a second surface, and a third surface, a first electrode disposed in the first surface and a second electrode disposed in the second surface, a first electrode tap, a second electrode tap, and a printed circuit board connecting the first electrode tap to the second electrode tap of the battery on the third surface. Soldering parts are formed on a first surface of the printed circuit board to connect an end of the first electrode tap to a first contact portion of the printed circuit board and an end of the second electrode tap to a second contact portion of the printed circuit board, respectively. A solder flow control member is formed on a second surface of the printed circuit board.

A bone conduction audio apparatus includes at least one ear hook assembly. A main circuit board is provided in the ear hook assembly. Each ear hook assembly includes an operating unit, a line concentrator and a bone conduction transducer. Each operating unit is electrically connected with corresponding line concentrator by contact springs or connecting wires, and connected with the main circuit board via the line concentrator. Each bone conduction transducer is electrically connected with the main circuit board via corresponding line concentrator. A controller of the main circuit board receives touch signals from all operating units to determine and initiate relating earphone operating. The bone conduction audio apparatus adopts bilateral triggering interaction mechanism. The line concentrator is combined with the suspended bone conduction transducer.

There is presented a hearing device for being placed at least partially in an ear canal. The hearing device includes a rechargeable battery, and at least two charging areas on the surface of the hearing device, the charging areas enabling recharging the rechargeable battery by applying a voltage from one charging area to another charging area. At least one charging area is positioned on the hearing device at the end of the hearing device facing into the middle ear during use and optionally out of contact with the walls of the ear canal during use.

An inductive charging case in accordance with certain embodiments presented herein comprises a base and a lid mechanically coupled together via a hinge mechanism. When the inductive charging case is in a closed arrangement (e.g., the lid is positioned adjacent to the base), the lid and base collectively define an interior volume that is configured to enclose an electronic device therein. The electronic device includes one or more rechargeable batteries, a receiver coil, and circuitry for recharging the one or more rechargeable batteries, while the inductive charging case includes inductive charging circuitry, including at least one inductive charging coil, that is configured to provide power to the electronic device which is then used to charge the one or more rechargeable batteries and/or power the electronic device.

An apparatus for drying a hearing aid and a hearing aid and a system formed by a hearing aid and a charging device. The apparatus has an energy storage device in the hearing aid, an energy transfer unit and a charging controller. The charging controller charges the energy storage device with energy taken in from the energy transfer unit. The apparatus furthermore has a temperature sensor in the hearing aid and the charging controller is designed to control a charging process in such a way that a thermal loss in the apparatus produces a predefinable temperature pattern in the hearing aid.

Embodiments of the present invent include a method of controlling unwanted vibration in a tympanic lens, wherein the tympanic lens comprises a perimeter platform connected to a microactuator through at least one biasing element, the method comprising the step of: damping the motion of the at least one biasing element. In embodiments of the invention, the at least one biasing element is a spring. In embodiments of the invention, the at least one bias spring is coated in a damping material.

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.

Embodiments of the invention include a method of charging a rechargeable battery, the method comprising the steps of: detecting the presence of a rechargeable hearing aid in a hearing aid recharger; generating a unique random ID in the charger; transmitting the unique random ID to the hearing aid using an extremely low power protocol; demodulating the unique ID in the hearing aid; using the demodulated unique ID in a low power protocol to advertise the hearing aid on a network which includes the charger; associating the hearing aid to the charger when the charger which broadcast the unique ID receives that unique ID from a hearing aid using a wireless protocol; using the wireless protocol to communicate between the associated charging station and hearing aid; radiating power from the charger to the hearing aid; and ending the association when the hearing aid is removed from the charger.
