Definitions

  • the invention relates to a hearing aid device with an antenna device.
  • the antenna device is designed to receive and / or transmit electromagnetic waves with a predetermined wavelength lambda.
  • the antenna device has an energy coupling device which is designed to supply or withdraw electrical energy from the antenna device.
  • Hearing aids are portable hearing devices that are used to care for the hard of hearing.
  • different types of hearing aid devices 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), e.g. also 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
  • CIC concha hearing aids or canal hearing aids
  • the hearing aids listed as examples 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. The damaged hearing is stimulated either mechanically or electrically.
  • hearing aids have an input converter, an amplifier and an output converter as essential components.
  • the input transducer is usually an acousto-electric 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. miniature speakers, or as an electromechanical converter, e.g. B. bone conduction receiver realized.
  • the amplifier is usually integrated in a signal processing device.
  • hearing aids were often viewed as individual systems that appropriately modified and amplified acoustic signals picked up by microphones.
  • Magnetic inductive radio systems have combined these individual systems into an overall system which, in addition to binaural coupling of the hearing aids, also allows wireless connection to external components such as mobile devices, multimedia units or programming devices.
  • this connection only works via an intermediate or relay station that converts the 2.4 GHz far-field connection of the external devices to the magnetic inductive near-field systems via Bluetooth. This relay station must always be in the vicinity of the hearing aid wearer because the range of the magnetic system in the near field is severely limited.
  • the pamphlet US7450078 B2 also describes a loop antenna that is implemented by a single-layer conductor loop in the hearing aid.
  • an antenna is presented that uses the side surfaces of the hearing aid through flexible printed circuit boards (PCB) to implement symmetrical or asymmetrical antenna structures.
  • PCB printed circuit boards
  • both side surfaces are viewed independently of one another and are only galvanically connected to one another through the antenna feed on the main circuit board.
  • the pamphlet US 2007/0080889 A1 also describes a loop antenna.
  • Loop antennas have a large loop area requiring space in the housing and must therefore be redesigned for each new hearing aid. In addition, these antennas show a great influence from nearby metallic objects or the head, which at 2.4 GHz causes detuning of the antenna as well as increased losses.
  • Antennas with parasitic elements also require a large area and can therefore not be flexibly integrated into a housing.
  • this object is achieved by a hearing aid device according to claim 1.
  • the hearing aid device relates to a hearing aid device with an antenna device, the antenna device being designed to receive and / or transmit electromagnetic waves with a predetermined wavelength lambda.
  • the antenna device has an energy coupling device which is designed to supply or withdraw electrical energy from the antenna device.
  • the antenna device has a first conductor and a second conductor that exchange energy with the energy coupling device stand.
  • the first and the second conductor extend away from the energy coupling device in different directions and are arranged at a small distance from a third conductor.
  • a first ohmic connection between the first conductor and the third conductor and a second ohmic connection between the second and the third conductor are arranged at a predetermined distance from the energy coupling device.
  • the distance here is to be understood as the length of a path between the energy coupling device and the ohmic connection along the first or second and / or the third conductor.
  • the antenna device forms a folded dipole which creates a closed electrical connection from the energy coupling device via the first conductor, the first ohmic connection, the third conductor, the second ohmic connection and the second conductor to the energy coupling device.
  • the first and third conductors or the second and third conductors initially extend away from the energy coupling device in different directions.
  • part of the first conductor and the second conductor also run essentially parallel to one another in the further course.
  • the folded dipole according to the invention differs from a loop antenna in that it has a small enclosed area, which is why the folded dipole advantageously requires less space and is easier to accommodate in the hearing aid device.
  • the folded dipole Compared to a monopole or dipole, the folded dipole has a significantly higher base point resistance at the energy coupling device. This can counteract the already very low base impedance of the antenna, which results from its proximity to the head. In addition, the ratio of radiation and power loss increases with the active component at the base point, and thus the radiation efficiency of the antenna.
  • the small distance between the first conductor and the third conductor and between the second conductor and the third conductor is less than 0.05 times lambda.
  • the space requirement of the antenna device is advantageously particularly small and due to the small value compared to the wavelength and the small enclosed area, the base point resistance increases, which advantageously leads to an increase in the active component at the base point and thus the ratio of radiation -and power loss and the radiation efficiency of the antenna improved.
  • the predetermined distance of the ohmic connection from the energy coupling device has a length in the range between lambda divided by two and lambda divided by eight.
  • the distance here preferably has a length of essentially lambda divided by four.
  • the radiation efficiency is ideal with a length of the free arms from a base point with the energy coupling device of lambda divided by four, i.e. a quarter of the wavelength of the wavelength to be emitted or received. Due to the influences of the environment and the geometry in which the antenna device is arranged differently from a plane, these distances can deviate from the ideal value. In particular, the arrangement and spacing of the conductors as well as the carrier material influence the speed of propagation and thus the effective length of the electromagnetic wave, so that an effective length of lambda divided by four can differ significantly from a corresponding value for a free wave in space.
  • this distance is predetermined by the geometry and an ohmic connection is arranged at this distance.
  • the ohmic connection can be given by a bend in which the first or second conductor merges into the third conductor, or simply by a conductive connection between first and third conductors or second and third conductors.
  • an antenna device can also advantageously be subsequently adapted or matched to different housing shapes in that the conductive connection is only applied afterwards, for example by means of a soldering point. In this way, one antenna can advantageously be used for various hearing aid devices under optimal conditions.
  • the antenna device has a fourth conductor.
  • the fourth conductor is arranged at a small distance from the first conductor and the second conductor and / or from the third conductor.
  • a distance of 0.05 times the wavelength lambda can be viewed as a small distance in the context of the invention.
  • an ohmic connection between the first conductor and the fourth conductor and between the second and the fourth conductor is arranged by the energy coupling device at the predetermined distance.
  • An additional fourth conductor makes it possible in an advantageous manner to change the electromagnetic properties of the antenna device by a further parameter without, for example, increasing the predetermined distance and thus adapting the antenna device to the hearing aid device under predetermined conditions.
  • the antenna device has a plane of symmetry which runs through the energy coupling device. It is particularly conceivable that the plane of symmetry of the antenna device is aligned essentially parallel to a plane of symmetry of a head of a hearing aid wearer when the hearing aid device is worn according to the application.
  • Such a symmetry with respect to the head of a hearing aid wearer advantageously allows a hearing aid to be used on both sides of the head without the properties of the antenna device being changed by the influence of the head. It is therefore possible with the antenna device according to the invention to use a hearing aid device for both sides of the head.
  • the hearing aid device has a structural element, the antenna device being part of the structural element.
  • a structural element within the meaning of the invention is a hearing aid device housing or a frame construction which carries various elements of the hearing aid device and which is arranged and fixed in the interior of the housing of the hearing aid device.
  • the first, second and third and / or fourth conductors of the antenna device can thus be arranged on the structural element or can also be integral components.
  • the antenna device is thereby fixed and protected in its position relative to components of the hearing aid device, so that defined and constant electromagnetic properties of the hearing aid device are ensured.
  • the first, second and third conductors are formed by structuring a conductive surface on the structural element.
  • the structuring of a conductive surface advantageously allows great freedom in shaping and also enables individual shaping during manufacture, for example by using a laser for structuring.
  • the antenna device is arranged on a flexible carrier element.
  • a flexible carrier element advantageously facilitates the introduction of an antenna device into the housing of the hearing aid device and an optimal use of the space.
  • an antenna device on a flexible carrier element enables the same to be exchanged easily.
  • the energy coupling device is coupled to the antenna device via a galvanic coupling.
  • a galvanic or ohmic coupling can advantageously be implemented in a space-saving manner and without additional components.
  • the energy coupling device is capacitively coupled to the antenna device.
  • a capacitive coupling advantageously enables coupling without there being a direct mechanical contact. This enables easier assembly.
  • the energy coupling device is inductively coupled to the antenna device.
  • An inductive coupling enables a transformation and thus an adaptation to different impedances in a simple way by choosing different inductances.
  • Fig. 1 shows the basic structure of a hearing aid device 100 according to the invention.
  • One or more microphones 2 for picking up the sound or acoustic signals from the environment are built into a hearing device housing 1 to be worn behind the ear.
  • the microphones 2 are acousto-electrical converters 2 for converting the sound into first audio signals.
  • a signal processing device 3, which is also integrated in the hearing aid housing 1, processes the first audio signals.
  • the output signal of the signal processing device 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal. If necessary, the sound is transmitted to the eardrum of the device wearer via a sound tube that is fixed in the ear canal with an otoplastic.
  • the hearing aid, and in particular that of the signal processing device 3, is supplied with energy by a battery 5 which is also integrated in the hearing aid housing 1.
  • the signal processing device 3 is also designed for processing electromagnetic waves.
  • it has an antenna device 20 and means 6 for generating and detecting electromagnetic waves and for decoding.
  • the representation in terms of shape and arrangement in Fig. 1 is only symbolic here and is explained in more detail for the following figures.
  • Fig. 2 shows a schematic representation of a folded dipole, which is a possible embodiment of an inventive Antenna device 20 represents.
  • the antenna device has a first conductor 21 and a second conductor 22 which extend in opposite directions away from an energy coupling device 26.
  • the energy coupling device 26 is a simple ohmic connection of the first conductor 21 and the second conductor 22 with an electrical waveguide 27. Because of the symmetrical properties of the antenna device and the characteristic impedance of 240 ohms for an ideal folded dipole at the base, i.e. the coupling point, a symmetrical stripline or stripline with an identical wave impedance can be used to ensure an optimal match. If the source or sink at the line 27 has a different characteristic impedance or an asymmetry, an adaptation by suitable balancing elements such as e.g. a balun possible.
  • capacitive or inductive energy coupling devices such as a transformer coil are also conceivable as energy coupling devices.
  • the antenna device 20 also has a third conductor 23, which is arranged at a distance D from the first conductor 21 and the second conductor 22.
  • the distance D is shown here disproportionately in comparison to the width 1 of the folded dipole 20. According to the invention, the distance is 0.05 times the wavelength of the electromagnetic wave to be emitted or received. Such a distance is to be regarded as a small distance in the context of the invention.
  • first conductor 21 and the second conductor 22 distal or opposite from the energy coupling device 26 are connected to the third conductor 23 via a first ohmic connection 24 or a second ohmic connection 25.
  • the connection can, as shown, take place in that the first, second and third conductors are made in one piece and are ohmic by a bend Connections 24, 25 merge into one another.
  • first, second and third conductors 21, 22, 23 are ohmically separated conductors or conductor tracks that are subsequently connected to one another by an ohmic connection, for example a solder bridge. In this way it is possible to subsequently determine and adapt the distance between the energy coupling device 26 and the ohmic connections 24, 25.
  • the length l is half the wavelength lambda of the electromagnetic wave. Due to the adjacent conductors, the carrier material of the conductors and the geometric arrangement of the arms in space, the length l and the length of the arms at which the folded dipole 20 fulfills the resonance condition for the frequency to be transmitted or received can differ significantly from the value lambda divided by two for the length l.
  • the wave resistance at the base point and / or a minimal reflection of the electromagnetic wave at the energy coupling device 26 can serve as criteria for the resonance condition.
  • the value for the total length l can be in the range from lambda to lambda divided by four.
  • the effective length l is lambda divided by two, the geometric length being in the range from lambda to lambda divided by four, and the length of an arm in the range from lambda divided by two to lambda divided by eight.
  • the length is in each case an integral multiple.
  • the energy coupling device 26 is arranged in the middle between the first conductor 21 and the second conductor 22, so that in the ideal folded dipole 20 the distance between the energy coupling device 26 and the first ohmic connection 24 and the second ohmic connection 25 is a quarter of the wavelength lambda. Due to a different distance D between the conductors, different geometry in the arrangement, deviating from a flat, elongated shape and the Environment can deviate from this value by a suitable length l. It is thus conceivable that the length l deviates by a tenth, a fifth or a quarter from the ideal length, the antenna device 20 nevertheless achieving the desired advantageous effects in the hearing aid device according to the invention. This can be especially true in the in Fig.
  • the antenna device has a further fourth conductor 28, which is arranged at a short distance from the first conductor 21 and the second 22 conductor and from the third conductor 23, with a further ohmic connection between the energy coupling device at the predetermined distance the first conductor and the fourth conductor and between the second and fourth conductor is arranged.
  • folding dipoles are also suitable for use in hearing aid devices according to the invention.
  • the base point impedance can be changed by changing the width of the first, second and third conductors running parallel. Another way of influencing the base point impedance is to add more parallel arms.
  • a folding dipole with three arms is in Fig. 4 evident.
  • the energy coupling device can be arranged on one of the outer arms or the middle arm.
  • the thicknesses of the first, second, third and fourth conductors 21, 22, 23, 28 and the distances between them are generally different and serve as degrees of freedom in design.
  • the integration of a three-armed folding dipole with the same thickness and spacing in a hearing aid device is described below Fig. 4 explained. Further degrees of freedom result from the addition of further arms or from an asymmetrical alignment of the antenna.
  • Fig. 3 is an illustration of a hearing aid device according to the invention in partial section.
  • a signal processing device 3 and an energy source 5 are arranged in a hearing aid device 100.
  • the signal processing device 3 has a transceiver module 6 as means 6 for generating and detecting electromagnetic waves and for decoding, which is shown in FIG Fig. 3 is not visible.
  • the transceiver module 6 is ohmically coupled to the first conductor 21 by the line 27.
  • the first conductor 21 is connected via the ohmic bridge 24 to the third conductor 23, which extends away from the energy coupling device 26 at a small distance from the first conductor 21.
  • a comparable arrangement for the second conductor 22 and the third conductor 23 is located behind the signal processing device 3 and is in FIG Fig. 3 not visible.
  • the signal processing device has two outer surfaces which are aligned essentially parallel to the outer walls of the housing 1 of the hearing aid device 100.
  • the hearing aid device 100 shown is a behind-the-ear hearing aid device that, according to the application, is worn behind the auricle of a hearing aid device wearer on the head.

  • first conductor 21 and the part of the third conductor 23 running parallel to it are arranged parallel to the surface 31 of the signal processing device 3 and thus parallel to the plane of symmetry of the head.
  • second conductor 22 and the part of the conductor 23 which are arranged on the surface 32 of the signal processing device 3.
  • the arrangement of first conductor 21, second conductor 22, third conductor 23, signal processing device 3 and energy coupling device 26 is in turn symmetrical to a plane that runs in the middle between and parallel to surfaces 31, 32 of signal processing device 3.
  • the hearing aid 100 can advantageously be arranged optionally on both ears of the hearing aid wearer without the transmission or Reception properties of the antenna device changes (apart from the reflection).
  • a hearing aid 100 according to the invention can therefore be worn equally on the left and on the right ear.
