Definitions

  • the invention relates to a hearing aid which is particularly designed as a classic hearing aid.
  • Hearing aids are typically traditional hearing aids that are used to provide support for people with hearing loss. In a broader sense, however, this term also refers to devices that are designed to support people with normal hearing. Such hearing aids are also known as "Personal Sound Amplification Products” or “Personal Sound Amplification Devices” (short: “PSAD”). These are not intended to compensate for hearing loss, but are used specifically to support and improve normal human hearing in specific hearing situations, e.g. to support hunters on the hunt or to support animal observation in order to be able to better perceive animal noises and other sounds made by animals, for sports reporters to enable improved speaking and/or speech comprehension in complex background noises, for musicians to reduce strain on the hearing, etc.
  • PSAD Personal Sound Amplification Devices
  • hearing aids typically have an input transducer, a data and/or signal processing device, which usually includes an amplifier, and an output transducer as essential components.
  • the input transducer is usually formed by an acousto-electrical transducer, for example a microphone, and/or an electromagnetic receiver, for example an induction coil.
  • An electro-acoustic transducer is usually used as the output transducer, for example a miniature loudspeaker (also known as a "receiver"). or an electromechanical transducer, for example a bone conduction receiver, and the data and/or signal processing device is usually implemented by an electronic circuit on a printed circuit board.
  • Such hearing aids also typically have an antenna unit or an antenna element as a so-called RF antenna, by means of which the hearing aid can be coupled in terms of signal technology, for example, to a control element (remote control) and/or to another hearing aid.

  • data possibly large amounts of data, are exchanged or transmitted wirelessly between the hearing aids on the right and left ears.
  • the exchanged data and information enable the hearing aids to be adapted particularly effectively to the respective acoustic situation. In particular, this enables a particularly authentic surround sound for the user and improves speech comprehension, even in noisy environments.
  • Hearing aids are preferably designed to be particularly space-saving and compact so that they can be worn as inconspicuously as possible by a hearing aid user. For this reason, smaller and smaller hearing aids are being manufactured which are increasingly comfortable to wear and are therefore hardly noticeable by a user when worn on or in one ear. However, due to the reduced installation space, it is becoming increasingly difficult to accommodate and/or install conventional antenna units or antenna elements for wireless signal transmission in such hearing aids.
  • ITE hearing aids which are usually custom-made and are installed deep in the ear canal or ear canal of the Such hearing aids are preferably designed to be so compact in terms of installation space that they are essentially invisible in the ear canal when worn.

  • E-units electrical and/or electronic units
  • an input converter e.g. a microphone
  • a battery or accumulator forms such an E-unit and/or a data and/or signal processing device mentioned above, hereinafter also simply referred to as a data processing unit, forms a corresponding E-unit.
  • a corresponding data processing unit typically has an amplifier or an amplifier function.

  • the transmission range is typically less than 18 m and, for example, 10 m.
  • the term range refers in particular to the signal range, i.e. the maximum distance of the respective communication or signal connection that may exist between a transmitter and a receiver so that communication between them is still possible.
  • the antenna unit is further preferably designed as a radio frequency antenna (RF antenna) or as an RF resonator, for example for a 2.4 GHz Bluetooth transmission using an ISM frequency band (ISM: Industrial, Scientific and Medical).

  • an auxiliary component 44 within the meaning of this application is typically an electrical component with an ohmic resistance, with a capacitance and/or with an inductance, for example a capacitor, a coil, a resistor or simply a conductor interruption, i.e. a gap.
  • a third embodiment of the coupling element 32 is shown in Fig.7
  • the coupling element 32 has only one conductor loop 46 instead of the previously described two conductor loops 34.
  • FIG. 8 A second variant according to Fig.8 differs from the execution according to Fig.2 by the design of the free arm 24 on the one hand and the design of the auxiliary element 22 on the other hand.
  • the auxiliary element 22 has Fig.8 no ring shape or at least no closed ring shape, rather the auxiliary element 22 is formed by an arc-shaped conductor with a free end.
  • the arc-shaped conductor spans a Arc area or angle area of more than 180° and therefore in turn forms a conductor loop or conductor loop.
  • the free end of the auxiliary element 22 and the free end of the free arm 24 are also designed as free ends with an end-side widening 48, so the corresponding free ends each end with a widening 48.
  • width is to be understood in particular as meaning that the transverse extension of the free end in the region of the widening corresponds to at least 1.2 times, preferably at least 1.5 times and more preferably at least 2 times the transverse extension of the free arm away from the widening or before the start of the widening.
  • a third variant according to Fig.9 differs from the execution according to Fig.8 in that the short-circuit arm 28 is not present.
  • the free arm 24 and the auxiliary element 22 are only connected to one another via the feed arm 30.
  • the feed arm 30, together with the adjoining conductor structure of the free arm 24 and the auxiliary element 22, forms a Z-shaped conductor structure or a Z-shaped course of the conductor tracks forming the antenna unit 20.
  • FIG.10 A fourth variant is outlined. This differs from the version according to Fig.2 by an auxiliary module 50 of the aforementioned type, which connects the free arm 24 with the auxiliary element 22.
  • the antenna unit 20 branches off according to Fig.10 an additional arm 52 extends from the free arm 24, specifically at a distance from the two ends of the free arm 24.
  • This additional arm 52 preferably points away from the auxiliary element 22 and also preferably has a free end with an end-side widening 48 of the previously mentioned type.
  • the further design variants of the antenna unit 20 according to Fig. 11 to Fig. 14 differ from the version according to Fig.10 by the position and, if applicable, the design of the auxiliary modules 54 to 60, whereby each auxiliary module 54 to 60 is designed as an auxiliary module of the type mentioned above.
  • the auxiliary modules 54 to 60 are therefore particularly designed as electrical modules of the designed in the manner described above, but depending on the application, possibly as different electrical components.
  • the design variant of the antenna unit 20 according to Fig. 15 represents a modification or further development of the antenna unit 20 according to Fig.9
  • the free arm 24 is designed as an extended free arm 24 and has a conductor extension 62 made of an electrically conductive material, through which, for example, a branch or ramification is formed.
  • the conductor extension 62 By means of the conductor extension 62, the free arm 24 is formed starting from the design of the free arm 24 according to Fig.9 preferably capacitively loaded and in this way a resonance condition for the antenna unit 20 is typically specified.
  • the conductor extension 62 in the exemplary embodiment is not formed by conductor tracks and is also not located in the previously mentioned plane, which is defined by a surface of the substrate 26. Instead, the conductor extension 62 is guided out of this plane or tilted out.
  • the conductor extension 62 in the exemplary embodiment is formed, among other things, by a connecting arm that protrudes from the substrate 26 and is connected to a conductor track end or a widened conductor track end of a conductor track on the substrate.
  • the corresponding conductor track forms the free arm 24 in the design of the antenna unit 20 according to Fig. 15 It corresponds to the design of the conductor track, which in the design of the antenna unit 20 according to Fig.9 the free arm 24 alone.
  • the connecting arm is connected to Fig. 15 a transverse conductor which forms a T-shape together with the connecting arm.
  • the transverse conductor is in turn connected to a U-shaped conductor element at both ends, with the opening of the U-shape preferably facing the substrate 26.
  • a previously described ladder extension 62 is not part of the free arm 24 but part of the previously described additional arm 52 or is connected to the previously described additional arm 52.
