摘要:
The present invention provides a method for charging a NiMH battery, comprising estimating a state of charge of the battery (100), determining an end of charging time based on the estimated state of charge (200), applying a constant charging current with a rate in the range from 0.9 C to 2.1 C to the battery until a threshold voltage is reached (300), upon reaching the threshold voltage, applying a constant charging voltage substantially equal to the threshold voltage to the battery (400) and continuing applying the constant charging voltage to the battery until the end of charging time is reached (500). Furthermore, a battery charger adapted to perform such a method as well as a system comprising such a battery charger and a hearing device powered by a NiMH battery are given.

An illustrative hearing device may include a battery compartment located in a housing and including a microphone and a battery. The housing may include a casing forming the battery compartment and a lid member having a hinged end pivotally connected to the casing such that the lid member is configured to pivot between an open position and a closed position relative to the casing. The lid member may be formed to define an opening through the lid member that is configured to allow the microphone and the battery to be in air communication with ambient air when the lid member is in the closed position.

A shell (10) for a hearing device, and a method of producing the same. The shell (10) comprises a sub-shell (11) produced by a generative method, and a thermoformed hull (12) covering the subshell (11). The sub-shell (11) comprises lateral openings (13) covered by the thermoformed hull (12) so as to render the shell (10) more flexible in the region of the openings (13), and thereby to relieve pressure exerted by the shell (10) due to dynamic changes in the shape of the wearer's ear canal during jaw movement.

This invention relates to an impression-taking pad (10) for taking an impression (20) of an ear canal (30) by an impression-taking material, having a lateral end (el) to be arranged away from a tympanic membrane (35) in said ear canal (30); and a medial end (em) to be arranged proximate to said tympanic membrane (35). The impression-taking pad (10) comprises an outer body (2) tapering from said lateral end (el) to said medial end (em). The impression-taking pad (10) further comprises an inner body (3) for releasable engagement with a tool (11, 12) for visual inspection of the ear canal (30), the inner body (3) being configured to support insertion of the impression-taking pad (10) in the ear canal (30) by the tool (11, 12). The impression-taking pad (10) comprises a duct (5) at least partially defined by the inner body (3), forming at least part of an optical path for visual inspection of the ear canal (30); wherein the optical path further comprises an inspection window (6), closing said duct (5), configured to support inspection of the ear canal (30) during the insertion of the impression-taking pad (10) in the ear canal (30); The impression-taking pad (10) is further configured to form an integral part of said impression (20). The present invention also relates to a method of taking an impression by the above defined impression-taking pad (10); as well as to a correlated impression-taking system comprising an aptly modified tool (11, 12) to cooperate with such an impression-taking pad (10).
摘要:
A hearing device to be worn in or at the ear of a user. The hearing device includes a housing for accommodating an electronic component, wherein the housing includes an electromagnetic wave shielding material and is formed with an indentation. The indentation provides a space at the outer side of the housing, allowing an antenna to be inserted into the indentation. The proposed hearing device achieves improved shielding of the antenna against electromagnetic waves radiated from at least one of the electronic components.

摘要:
An antenna module for a hearing device includes a hollow core provided with an axial passageway and a winding around the core which is connectable with a hearing device. The antenna module is arranged to be at least partially contained within the ear canal of a user. This enables the antenna to be separated from sources of interference, since it can be positioned inside the ear canal away from hearing device electronics, thus reducing requirements for shielding and/or compensation. The invention further relates to an ear tip and a hearing device including such an antenna module.

A method for producing a hearing device shell includes producing a 3D-model of the shell by using ear canal measurement data; deriving a first set of data from the 3D-model; manufacturing a hearing device shell preform based on the first set of data such to assume an outer surface designed larger than the targeted final shape of the hearing device shell; calculating a second set of data from the 3D-model; and machining the surface of the hearing device shell preform based on the second set of data resulting in the hearing device shell.
