Definitions

  • the invention relates to a hearing aid device with a housing, with a frame inserted in the housing for receiving electrical or electronic assemblies that comprise a transmitting and / or receiving unit for electromagnetic waves, and with an associated antenna, the antenna being an integral part of the Frame, is designed as a stamped and bent part or as an insert made of metal.
  • hearing aids are known per se and are available in various publications, for example the WO 2014/090419 A1 , described in more detail.
  • the generic term “hearing aids” includes, on the one hand, portable hearing devices that are used to supply the hearing impaired.
  • hearing aids such as behind-the-ear hearing aids (BTE), hearing aid with external receiver (RIC: receiver in the canal) and in-the-ear hearing aids (ITE), for example Concha hearing aids or canal hearing aids (ITE, CIC) provided.
  • BTE behind-the-ear hearing aids
  • RIC hearing aid with external receiver
  • ITE in-the-ear hearing aids
  • ITE Concha hearing aids or canal hearing aids
  • ITE Concha hearing aids or canal hearing aids
  • CIC Concha hearing aids or canal hearing aids
  • the hearing aid devices listed by way of example are worn on the outer ear or in the auditory canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market
  • hearing aid devices have also been developed to support people with normal hearing.
  • Such hearing aids are also called “Personal Sound Amplification Products” or “Personal Sound Amplification Devices”("PSAD” for short) designated.
  • PSAD Personal Sound Amplification Devices
  • These hearing aids are not intended to compensate for hearing loss. Rather, such hearing aids are specifically used 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 sounds and other noises produced by animals, for sports reporters to a to enable improved speaking and / or speech understanding in complex background noise, for musicians, to reduce the burden on hearing, etc.
  • hearing aids have an input transducer, an amplifier and an output transducer as essential components.
  • the input transducer is usually an acousto-electrical transducer, e.g. B. a microphone, and / or an electromagnetic receiver, e.g. B. an induction coil.
  • the output transducer is usually an electroacoustic transducer, e.g. B. as a miniature speaker (also referred to as "listener"), or as an electromechanical converter, e.g. B. realized as a bone conduction receiver.
  • the amplifier is usually integrated in a signal processing device.
  • Modern hearing aids are often equipped with transmitting and / or receiving units that enable wireless communication with other electronic devices, in particular with other hearing aids (e.g. to form a binaural hearing aid system), remote controls, programming devices or mobile phones.
  • the wireless communication often takes place by means of electromagnetic waves in the radio or radio frequency range, e.g. using Bluetooth technology at 2.4 GHz.
  • the problem with hearing aids is the implementation of the (RF) antennas required for this, since standard antenna designs cannot easily be used due to the free-space wavelength of more than 10 cm (corresponding to the frequency range mentioned above) and the small electrical volume of conventional hearing aids. This problem is becoming increasingly important with the progressive miniaturization of hearing aids.
  • the antenna is formed by a conductive structure which is an integral part of the (electronics) frame of the hearing aid device. This enables the antenna to be accommodated in a space-saving manner in the housing of the hearing aid device.
  • the antenna with the frame can be installed in a variety of different housings without having to constantly redesign the antenna concept.
  • the invention is based on the object that from WO 2014/090419 A1 to further improve the known antenna concept.
  • the hearing aid device comprises a housing and an (electronics) frame inserted in the housing for receiving electrical and / or electronic assemblies.
  • the assemblies received in the frame include a transmitting and / or receiving unit for electromagnetic waves, in particular radio waves in the MHz or GHz range, for example 2.44 GHz (corresponds approximately to a wavelength of 65 mm).
  • the hearing aid device furthermore comprises an antenna which is assigned to the transmitting and / or receiving unit and is designed as an integral part of the frame.
  • An integral component here means in particular that the antenna or a conductive structure that partially or completely forms the antenna cannot be detached from the frame without being destroyed and / or is essentially part of the outer shape of the frame, i.e.
  • the antenna is designed as a stamped and bent part (connected to the frame) or as an insert part made of metal (connected to the frame).
  • the antenna furthermore has a first part which, in particular, has a winding course or is designed as an open loop with two ends.
  • the first part usually has a non-straight course, which typically shows several changes in direction, that is, for example, is designed in a meander shape.
  • a segment along the course of the first part forms a first auxiliary structure which has the shape of a closed loop.
  • this auxiliary structure With this auxiliary structure, the effective length of the structure forming the antenna is then increased, among other things, without the need for a larger area for accommodating the antenna. This means that in this way the space available for the antenna or the area available for the antenna is used more effectively.
  • this auxiliary structure can be used to favorably influence the radiation characteristics of the antenna, in particular with regard to the intensity with which the radiation is carried out at which solid angle.
  • the auxiliary structure enables a relatively good impedance matching to an impedance of 50 ⁇ .
  • the frame has an upper side, an underside and two mutually opposite flanks and if the first auxiliary structure is positioned on one of the two flanks of the frame.
  • a side of the frame that connects the top and bottom of the frame is referred to here as a side area or flank.
  • the corresponding designation of the sides of the frame with top, bottom and flank relates to the intended alignment of the hearing aid relative to a wearer, user or user of the hearing aid while the latter is wearing the corresponding hearing aid.
  • the underside of the frame then typically points in the direction of the torso of the user, carrier or user and one of the two flanks or one side area points in the direction of the head, while the other of the two flanks or the other of the two side areas is directed away from the head.
  • the antenna also has a second part, which in particular has a winding course or is designed as an open loop with two ends.
  • the two parts of the antenna are preferably electrically short-circuited to one another with one of their ends in each case via a bridge and the bridge is in particular designed as an integral part of the frame.
  • Such a bridge or part of such a bridge is formed, for example, by at least one electrical conductor track which completely or at least partially bridges the distance between the ends of the parts of the antenna to be short-circuited and which is therefore referred to below as "bridge conductor".
  • the or each bridge conductor - like the entire antenna - is designed as an integral part of the frame, stamped and bent part or insert.
  • the two parts of the antenna are positioned on the two opposite flanks of the frame.
  • the bridge is then preferably guided over the top on the frame.
  • the frame is also formed from two frame halves, the first part of the antenna being arranged on one of the two frame halves and the second part of the antenna being arranged on the other of the two frame halves.
  • the two parts that is to say the first part of the antenna and the second part of the antenna, are designed to be symmetrical to one another with respect to a plane of separation separating the frame halves.
  • the symmetrical design of the antenna advantageously facilitates side-independent use of the hearing aid device. In other words, this feature enables one and the same housing, including the frame and the components accommodated therein, to be used both for use on the left ear and for use on the right ear.
  • the two parts of the antenna can also be designed asymmetrically to one another.
  • the asymmetrical design of the two parts is preferred whenever a symmetrical design of the parts would lead to stronger electromagnetic interference between the antenna and the other electrical or electronic assemblies in or on the frame.
  • the asymmetry between the two parts is preferably small.
  • the parts of the antenna are designed to be as symmetrical as possible, in particular while avoiding the aforementioned interference.
  • the antenna is usually designed as a folded dipole antenna and, according to an embodiment variant, the two ends of the two parts of the antenna are arranged on the same longitudinal end of the frame.
  • a segment along the course of the second part of the antenna preferably forms a second auxiliary structure which has the shape of a closed loop.
  • each auxiliary structure has an essentially elliptical shape.
  • the main axis of the elliptical shape is then aligned vertically, i.e. vertically in relation to the earth system.
  • it tapers to a point at both ends of its main axis.
  • each part of the antenna then preferably has a (path) length which corresponds to a good approximation to a quarter or an eighth of the wavelength of the radio waves for which the transmitting and / or receiving unit is designed.
  • the frame is made of a non-conductive material, in particular a plastic, which has a higher permittivity than the material of the housing.
  • the frame material of the hearing aid device according to the invention in particular also has a higher permittivity than materials that are usually used for electronic frames of conventional hearing aid devices.
  • the frame material of the hearing aid device according to the invention has a relative permittivity of at least 3.8, preferably at least 4.5. It has been shown that the increased permittivity of the frame material through dielectric interaction with the electromagnetic field generated or received by the antenna enables a decisive shortening of the antenna length for a given transmit / receive characteristic. This, in turn, represents a significant advantage in terms of housing the antenna on the frame.
  • the surface of the frame is preferably first structured in such a way that when the conductive layer is applied, it is only applied in accordance with the structuring. This is done, for example, by means of direct laser structuring (Laser Direct Structuring, LDS for short).
  • LDS Laser Direct Structuring
  • the surface of the frame is treated with a laser in such a way that a conductor path is only deposited at the treated areas in a galvanic bath.
