- part of an antenna may be included in the in-the-ear housing, such as at least partly coiled in the in-the-ear housing.
- a telecoil may be provided in the hearing aid, such as in the housing to be positioned behind the ear.
- a recharge system may be provided to allow the battery of the hearing aid to be recharged, e.g. inductively recharged.
- a hearing aid comprising such as speaker unit as described above may be, but does need to be, described as a hearing aid device comprising a first portion adapted for being arranged behind an ear of a user for providing a signal, a second portion adapted for being arranged in or at the ear canal of the user, wherein an output transducer configured to converting the signal to an acoustic output is arranged in the second portion, a coupling element coupled to the first portion, and wherein the coupling element is adapted for transmitting at least the signal, wherein the second portion is coupled to the coupling element at the end opposite of the first portion, an antenna comprising an external antenna part and an internal antenna part, where the internal antenna part includes a first antenna element, a second antenna element, where a first end of the second antenna element is arranged at one end of the first antenna element and is connected thereto, and where a second end of the second antenna element is connected to a ground plane, and a third antenna element which is spaced at a distance from the second antenna element and connected to
- the entity including an interface to a behind-the-ear housing and the output transducer and the coupling element is often termed a speaker unit.
- a speaker unit on its own may be, but does need to be, described as speaker unit comprising a coupling component for a hearing aid device, wherein the coupling element comprises an interface configured to establish electrical connection to a first portion having a housing configured to be arranged behind the ear of a user, wherein the coupling element comprises an in-the-ear part having a housing configured to be arranged at least partly in the ear canal of the user, and wherein the coupling component comprises a connecting part connecting the interface to the in-the-ear housing, where the connection member comprises a plurality of electrical conductors and at least one electrical conductor being part of an antenna, at least a multitude of the plurality of electrical conductors being connected to a corresponding multitude of connection point on a substrate arranged in the in-the-ear housing, one decoupling device arranged between a first connection point of the multitude of connection points and a second of the multitude of connection points.
- the coupling element comprises an interface configured to establish electrical connection to a first portion having a housing configured to be arranged
- the present disclosure also relate to the following points.
