Definitions

  • the present invention relates to a hearing aid having a signal receiving means, a signal processing means for processing a signal from the signal receiving means, a magnetically operated speaker means which converts an output of the signal processing means into an output sound, and a shielding means connected between the speaker means and the signal processing means for reducing electromagnetic interference the signal processing device is arranged by the loudspeaker device.
  • Hearing aids are portable hearing aids that are used to care for the hearing impaired.
  • different types of 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 (IDO), e.g. Concha hearing aids or canal hearing aids (ITE, CIC).
  • BTE behind-the-ear hearing aids
  • RIC hearing aid with external receiver
  • IDO in-the-ear hearing aids
  • ITE canal hearing aids
  • the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
  • Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
  • the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
  • the amplifier is usually integrated in a signal processing unit. This basic structure is in FIG. 1 using the example of a behind-the-ear hearing aid shown. In a hearing aid housing 1 for carrying behind the ear, one or more microphones 2 for receiving the sound from the environment are installed.
  • a signal processing unit 3 which is also integrated in the hearing aid housing 1, processes the microphone signals and amplifies them.
  • the output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal.
  • the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
  • the power supply of the hearing device and in particular the signal processing unit 3 is effected by a likewise integrated into the hearing aid housing 1 battery. 5
  • amplifiers, receivers (loudspeakers) and antennas for wireless communication are usually arranged very close to each other, so that these components interfere with each other much more strongly than is the case in other applications in which similar components occur.
  • Particularly critical in a hearing aid is the disturbance of the wireless communication by electromagnetic radiation of the listener in the communication frequency band as well as interference of the amplifier by electromagnetic radiation of the listener in the audio frequency band.
  • the influence of the handset or loudspeaker on the rest of the signal processing is therefore lower in a mobile telephone than in a hearing aid, because the power of the listener in a hearing aid is always higher than in a mobile phone. This is because having a hearing aid is sufficient high levels must be generated in order to compensate for hearing loss can.
  • an amorphous magnetic shielding tape is known.
  • This shielding tape consists of five layers, a backing paper, an amorphous metal strip and a PET film. In between there is an adhesive layer in each case.
  • the shielding tape can be used to reduce electromagnetic influences.
  • Par is a polymer bonded soft magnetic material for magnetic core applications and EMI filters.
  • amorphous metals are produced by very rapid cooling. As a result of the rapid cooling, the metal atoms remain in a largely disordered state. The resulting amorphous structure leads to a high electrical resistance and a soft magnetic behavior.
  • the metal for example, alloys are used in which 70 to 85% of the atoms are transition metals such as iron, cobalt and nickel and 15 to 30% semi-metals such as silicon and boron. In these compositions, the energy in the crystalline state is hardly lower than in the melt. The tendency to crystallize is therefore only weak.
  • Hearing aids are currently used mostly listeners who are shielded against radiation in the audio frequency range by a housing of so-called mu-metal.
  • a screen foil made of copper may be placed around the listener to improve the shielding effect in the communication frequency band.
  • mu-metal shielding has little effect because of its high permeability and low conductivity.
  • Copper on the other hand shields magnetic radiation or low frequencies only insufficiently. This means that both types of shielding are required.
  • the object of the present invention is therefore to simplify the shielding of a listener in a hearing aid.
  • both electrical and magnetic fields can be shielded. So it is for the shield in the hearing aid communication frequency band (eg at 3 MHz) and for shielding in the audio frequency range only a single material or a single shielding necessary.
  • the structure of a hearing aid having a wireless communication connection can be significantly simplified.
  • the signal processing device of the abovementioned hearing device thus has a transmission unit, and the shielding device is arranged to protect the transmission unit mainly between the latter and the loudspeaker device.
  • the influence of the speaker device on the transmission unit can be reduced.
  • the shielding device forms the housing of the loudspeaker device. In this way, it can be achieved that the loudspeaker device is well shielded in all spatial directions and, in addition, no separate shielding device is necessary in addition to the housing of the loudspeaker device.
  • the shielding housing may be formed multi-layered, wherein a layer thereof serves as a carrier, on which a layer of the amorphous metal is formed. This makes it possible to produce a mechanically very stable housing.
  • the shielding device can also be designed so that it shows a clear shielding effect in the single-digit MHz range.
  • the shielding device is effective in the frequency range that is typically used for wireless communication in hearing aids.
  • the shielding device may have a preferred magnetic direction, which runs essentially parallel to a magnetic circuit of the loudspeaker device. As a result, the shielding effect against stray fields of the magnetic circuit is particularly high.
  • the shielding device may have an electrical preferred direction that is substantially perpendicular to a magnetic circuit of the speaker device runs. As a result, eddy currents are promoted whose orientation is also optimized with regard to the reduction of stray fields.
  • the hearing aid is designed as in-the-ear hearing aid.
  • Such hearing aids require a particularly small space, and the double shielding effect of the amorphous metal (audio frequency range and communication frequency range) in a single shielding is then particularly favorable.
  • FIG. 2 schematically shows a handset of a hearing aid, as used for example in a BTE hearing aid or in an ITE hearing aid.
  • the listener represents the speaker device of the hearing aid or is at least part of it. It is used to generate an output sound of the hearing aid on the basis of a signal which it receives from a hearing aid-internal signal processing device.
  • the signal processor typically includes an amplifier and, optionally, filters and other signal processing components. It receives its input signal from a signal recording device, which typically contains at least one microphone and / or an electromagnetic receiver, eg a coil.
  • a modern hearing aid usually contains a transmission device for wireless communication with an external device.
  • the transmission device has, for example, an antenna or a coil for inductive transmission.
  • the wireless communication takes place for example in one or more frequency bands in the range of 3 MHz.
  • the in FIG. 2 Illustrated example listener is an electrodynamic speaker.
  • electrical input signals in vibrations of an in FIG. 2 converted membrane not shown.
  • the vibrating diaphragm causes the immediately adjacent air to vibrate, producing the desired sound.
  • This sound leaves the listener at a sound outlet 10. From there it is led directly or with the help of a sound tube to the eardrum of the hearing aid wearer.
  • the listener For the electrodynamic conversion of an electrical input signal into the sound output signal, the listener here has a magnet arrangement 11, which converts the electrical signal into mechanical vibrations.
  • the magnet arrangement has in the present case a hard or soft magnetic block 12, which is designed cuboid.
  • This metal portion 13 has a first leg 14, which here protrudes perpendicularly from the metal block 12 and is firmly connected thereto.
  • a second leg 15 of the U-shaped metal portion 13 extends parallel to the first leg 14 and also parallel to a side 16 of the cuboid metal block 12 which is perpendicular to the side 17 from which the first leg 14 protrudes. In the unloaded state there is a certain distance between the leg 15 and the side 16 of the metal block 12.
  • the first leg 14 and the second leg 15 of the U-shaped metal portion 13 are interconnected by an arch member 18. Since the metal portion 13 only at the first Leg 14 is fixedly connected to the metal block 12 and is free at its second leg 15, the latter can perform 12 due to the distance to the side 16 of the metal block 12 vibrations.
  • a coil 19 is wound, the terminals 20 are guided here for simplicity down.
  • the coil 19 generates a magnetic flux through the first leg 14.
  • the magnetic circuit is closed via the arcuate element 18, the second leg 15, the air gap between the second leg 15 and the metal block 12 and finally via the metal block 12 itself back to the first Leg 14. If the coil 19 is energized, the metal block 12 attracts the free end of the second leg 15 in the rhythm of the magnetic flux or the electrical signal, so that this free end performs appropriate vibrations.
  • the attached to the free end of the second leg 15 membrane (not shown) then generates the corresponding sound.
  • the used as a transducer magnet assembly 11 unintentionally radiates magnetic fields as interference from the outside. All the more so as powerful hearing aids are used in hearing aids, which must compensate for the hearing loss of a hearing aid wearer. These interference fields affect components in the immediate vicinity of the listener. Since hearing aids and in particular ITE hearing aids inherently only take up a small amount of space, the remaining in a hearing aid necessary electrical components are relatively close to the listener. That All electrical components can be influenced by the interference fields of the listener.
  • the handset is operated in the audio frequency range.
  • this does not mean that interference field components exist exclusively in the audio frequency range. Rather, harmonics of the useful signal or of the useful field are also generated as interference components.
  • this frequency range also works, for example, an electromagnetic communication system, which is integrated into the hearing aid.
  • the hearing aid has an antenna or coil for wireless communication in the single-digit MHz range, interfering components of the listener can definitely decisively influence the communication system. It is important to curb these interfering components effectively.
  • the magnet assembly 11 is installed in a housing 21 which is at least partially made of an amorphous, soft magnetic metal of the type mentioned.
  • This housing 21 completely surrounds the magnet arrangement 11.
  • the Schallauslassstutzen 10 is here integrally connected to the housing 21 and formed of the same material as the housing 21 itself.
  • an opening 22 in the housing 21 In the vicinity of the coil 19 of the magnetic transducer is an opening 22 in the housing 21. Through this opening, the connecting lines 20 of the coil 19 led to the outside.
  • FIG. 2 shown structure of the listener and in particular the housing 21 is merely exemplary.
  • the housing 21 in FIG. 2 half open, so that the magnetic transducer located therein is recognizable.
  • the housing 21 thus represents a shielding device, which is part of the speaker device here.
  • a shielding foil, a shielding band or another shielding element between the receiver or the loudspeaker device and any other signal processing component of the hearing device. It is only important that the respective shielding means comprises said amorphous, soft magnetic metal.
  • the amorphous magnetically soft metal used also has a preferred direction of nanocrystalline structures. This anisotropy causes the shielding device (in the case of the example of FIG. 2 the housing 21) has a preferred magnetic direction 24 and a preferred electrical direction 25. Both preferred directions 24 and 25 are perpendicular to each other.
  • the housing 21 has cuboid shape here.
  • the individual walls of the housing extend substantially parallel to the directly opposite sections of the magnetic circuit of the magnet arrangement 11.
  • the upper side 26 of the housing 21 runs parallel to the second leg 15 of the magnetic circuit.
  • the underside 27 of the housing 21 runs parallel to the immediately adjacent first leg 14 of the magnetic circuit.
  • the amorphous, soft magnetic metal is formed so that the magnetic preferred direction 24 is parallel to the second leg 15 and thus parallel to the guided therein magnetic flux. This low-frequency interference fields of the magnet assembly 11 can be attenuated.
  • the material of the housing 21 has, as already indicated, perpendicular to the magnetic preferred direction 24, an electrical preferred direction 25. This means that in this direction, the electrical resistance is lower than in the orthogonal direction thereto. Since the housing 21 completely surrounds the magnet arrangement 11, an electrical circuit is thus formed around the magnet arrangement 11 in accordance with the preferred direction 25, the axis of which is perpendicular to the axis of the magnetic circuit. In this electrical circuit eddy currents can flow, which are induced by high-frequency interference components of the magnet assembly in the housing 21. This leads to a corresponding shielding of the high-frequency components to the outside.
  • amorphous, soft magnetic metals with preferential direction (anisotropy) of the nanocrystalline structure Such materials, which are used according to the invention for shielding low-frequency alternating fields because of their better processability as an alternative to Mu metal, have a high permeability in one spatial direction and at the same time are good conductors in the other spatial direction.
  • the low-frequency magnetic field as mentioned, can be conducted in one spatial direction, while the eddy currents, which provide for the shielding of high-frequency fields, can flow with little resistance.
  • the necessary shielding effect can be achieved with only one material. This assembly steps can be saved, and the shielded handset or the entire hearing aid can be built smaller.
  • the shielding device or the housing 21 have said amorphous, soft magnetic metal with preferential direction of the nanocrystalline structures.
  • the metal may be applied / embedded in the form of a metal layer on or in one or more other material layers. Due to the multi-layeredness, other material properties of the housing, e.g. increased strength, be promoted.
