Definitions

  • the invention relates to a hearing aid.
  • Hearing aids typically refer to traditional hearing aids designed for people with hearing loss. However, in a broader sense, the term also encompasses devices designed to support people with normal hearing. These are also known as “Personal Sound Amplification Products” or “Personal Sound Amplification Devices” (PSADs). These are not intended to compensate for hearing loss, but rather are specifically designed to support and enhance normal human hearing in particular situations. For example, they can assist hunters while hunting or wildlife observation by enabling them to better perceive animal sounds and other noises produced by animals; they can help sports reporters to improve speech and/or speech comprehension in noisy environments; and they can help musicians reduce strain on their hearing.
  • PSADs Personal Sound Amplification Products

  • hearing aids typically comprise an input transducer, a data and/or signal processing unit (usually including an amplifier), and an output transducer as their essential components.
  • the input transducer is generally an acousto-electrical transducer, such as a microphone, and/or an electromagnetic receiver, such as an induction coil.
  • the output transducer is usually an electro-acoustic transducer, such as a miniature loudspeaker (also called a "receiver"), or an electromechanical transducer, such as a bone conduction receiver.
  • the data and/or signal processing device is usually implemented by an electronic circuit on a printed circuit board.
  • Such hearing aids typically also feature an antenna unit or antenna element, known as an RF antenna, which allows the hearing aid to be connected to a control unit (remote control) and/or another hearing aid.
  • an antenna unit or antenna element known as an RF antenna
  • the same antenna unit or element is usually used for both transmitting and receiving data.
  • a binaural hearing device two such hearing aids are worn by one user, with a wireless signal connection between the antenna units or elements of the hearing aids during operation.
  • data potentially large amounts of data, are wirelessly exchanged or transmitted between the hearing aids in the right and left ears.
  • the exchanged data and information enable particularly effective adaptation of the hearing aids to the specific acoustic environment. In particular, this provides the user with a more authentic spatial sound and improves speech intelligibility, even in noisy environments.
  • Hearing aids are preferably designed to be particularly space-saving and compact, so that they can be worn as discreetly as possible. Therefore, increasingly smaller hearing aids are being manufactured, offering ever greater wearing comfort and thus being barely noticeable to the user when worn in or on the ear. However, due to the resulting reduced installation space, it is becoming increasingly difficult to accommodate and/or integrate conventional antenna units or antenna elements for wireless signal transmission into such hearing aids.
  • ITE in-the-ear
  • Such hearing aids are preferably designed in such a way as... They are designed to be compact in terms of installation space, so that when worn they are essentially invisible in the ear canal.
  • the hearing aid according to the invention is preferably designed as a hearing aid of the type mentioned above and is typically designed as an in-the-ear hearing aid (IdO hearing aid), for example as a channel hearing aid (ITE: In-The-Ear, CIC: Completely-In-Channel, IIC: Invisible-In-The-Channel).

  • the base plate and the housing shell also preferably enclose the hearing aid externally.

  • the hearing aid includes a transmitting and receiving unit for sending and receiving electromagnetic waves, comprising an electronic circuit for generating a transmit signal and an antenna unit or antenna element coupled thereto.
  • This antenna unit typically includes or forms an RF antenna of the type mentioned above. Therefore, for the purposes of this application, electromagnetic waves are to be understood in particular as radio signals, also referred to as RF signals.
  • the transmitting and/or receiving unit is now functionally suitable and configured for generating and/or evaluating RF signals that can be transmitted or received via the antenna unit.
  • the transmission range is typically less than 20 m and, for example, 10 m.
  • range refers specifically to the signal range, i.e., the maximum distance between a transmitter and a receiver that allows for communication between them.
  • the transmitting and/or receiving unit is preferably designed for so-called far-field radiation.
  • the antenna is designed for far-field radiation. This means that during transmission, a so-called far-field radiation pattern is achieved, in which electromagnetic waves emitted by the antenna unit propagate into the far field, also known as the Fraunhofer region. Information transmission is therefore preferably not achieved through inductive and/or capacitive coupling between transmitter and receiver.
  • An electric field, or predominantly an electric field, is typically generated at or with the antenna unit itself. At least the electric component of the field is dominant in the immediate vicinity of the antenna unit.

  • the antenna arm and the shielding element are formed from the same material, typically the same metal or the same metal alloy.
  • the shielding effect of the shielding element advantageously allows for greater freedom in the design of the hearing aid and, in particular, in the design of the antenna unit, such that when choosing the resonance frequencies or the resonance frequency for the antenna unit, possible interference frequencies from the E-units do not have to be taken into account, so that the antenna unit and E-units can be optimized virtually independently of each other.
  • the hearing aid will then also feature such a simpler amplifier or data processing unit.
  • an amplifier can be positioned more freely, meaning that fewer factors need to be considered when selecting a suitable position for the amplifier. In such cases, it is usually referred to as a "floating amplifier.”
  • the additional freedom in specifying the resonant frequency or frequencies also makes it possible in some cases to dispense with matching elements such as an ohmic resistor, an inductor, a capacitor and/or a so-called balun, and in the case of at least In one embodiment, the antenna unit does not have such an adjustment element.
