Definitions

  • the present invention relates to a hearing device with a component that can be worn in the ear canal, which has a receiving unit for the wireless reception of signals. Moreover, the present invention relates to a method for generating a sound signal or for transmitting energy in an ear canal. In particular, the invention relates to hearing aids which are arranged in the ear canal.
  • CICs Deeply in the ear canal hearing aids, so-called CICs (completely in the channel), are problematic for several reasons.
  • the user finds it uncomfortable to push the device very far into the ear canal.
  • hearing aids that are completely housed in the ear canal must be removed from time to time, for example to change the battery and used again.
  • the hearing aid is equipped with a first component located in the ear canal.
  • a second component, with which signals from the first can be received, is located outside the ear canal.
  • DE 38 26 294 A1 a hands-free device for communication systems.
  • a player is carried in an ear. It receives its signals from an out-of-ear transmitter over a wireless link.
  • the publication WO 2006/042298 A2 describes a hearing system with photomechanical conversion.
  • the photomechanical transducer In the middle ear or on the drum tube is the photomechanical transducer, which is excited by light, which is modulated with the desired signal to vibrate.
  • this object is achieved by a hearing device according to claim 1.
  • the invention provides a method according to claim 7.
  • the idea is used of arranging a component which itself has no energy store very deep in the auditory canal and to transmit the signals or the energy wirelessly to this component.
  • a component located further out in the ear canal transmits the signal or the energy to the deeper-seated component.
  • the deeper-seated component only has to be removed very seldom, while the outside-sitting component can easily be removed by the user, for example, for battery replacement.
  • the hearing device is designed as a hearing aid.
  • CIC devices can thus profit from the advantage according to the invention.
  • the first component ie the more deeply seated component, has a seal for a soundproof seat in the auditory canal. This improves the efficiency of sound transmission from the first component to the eardrum.
  • the first component may have a receiving coil. This means that signals or energy can be transmitted inductively to the first component.
  • the first component also has an electromechanical transducer to convert the signals to acoustic waves.
  • the first component may comprise a magnetically active membrane. This is preferably coated with a ferromagnetic fluid. With the aid of a magnet placed in the auditory canal, the membrane can be deflected to generate sound.
  • the first component consists exclusively of the magnetically active membrane and the seal or another passive holder for fixing the membrane in the ear canal. This practically allows a loudspeaker to be realized in which the auditory canal wall represents the loudspeaker housing.
  • FIG. 1 is a structurally divided into two parts hearing aid in an ear canal or ear canal 1 used.
  • a second component 2 serves to generate a signal in the ear canal 1.
  • the second component 2 comprises a transmitting coil 3 arranged in the auditory canal 1 and provided with a transmission coil 3 in the auditory canal 1 FIG. 1 not shown, external auditory signal processing, microphones and a battery is connected.
  • the entire signal processing including microphone, battery and the transmitting coil can also be arranged in the ear canal or partially in the ear canal.
  • a first component 4 of the hearing device is placed further inside the ear canal 1. It consists here of a receiver coil 5, an electroacoustic transducer 6 and a seal 7 and optionally from additional electronics.
  • the first component 4 is batteryless and converts the signals received by means of the coil 5 and possibly further processed by the signal processing into sound signals for direct reception by the in FIG. 1 unreproduced eardrum.
  • the transmitting coil 3 of the second component 2 sends the output signal and optionally energy for the signal processing in magnetic form to the deep-seated in the ear first component 4.
  • FIG. 1 the supply of the electronics for the signal processing and the receiver or sound transducer 6 via a magnetic field by arrows 8 symbolizes.
  • the second component 2 consists here, as in the first embodiment, inter alia of a transmitting coil 3, which is placed in the ear canal 1. It is in magnetic interaction (arrows 8) with the first component 4, which is located lower in the ear canal.
  • This first component 4 consists here only of a magnetically active membrane 9, which is held by means of a holder or seal 10 in the ear canal 1.
  • the magnetically active membrane 9 has a ferromagnetic coating, which allows a deflection of the membrane by means of the magnetic field generated by the second component 2.
  • the membrane is coated with a ferromagnetic liquid which dries after application.
  • the first component 4 apart from the seal 10 here exclusively consists of the passive membrane 9, a signal coding in the signal transmission between the two components 2 and 4 is not possible.
  • electronics used under certain circumstances enable coding during signal transmission within the ear canal.
  • the hearing aids shown in detail above have many advantages.
  • the first component 4 or its seal 7, 10 can remain permanently in the ear canal 1, so that the ear doctor, for example, only has to place it once. This is possible because the first component 4 is batteryless.
  • the deep seat of the first component allows an effective acoustic supply, in particular a high output level with relatively low energy consumption.
  • the transmitting coil 3 of the second component can be mounted relatively large area along the ear canal 1, which leads to a more effective magnetic field coupling.
  • the second component 2 can also, for example, be a hearing aid that is not individually matched to a wearer and whose earpiece does not have to be individually adapted (so-called open-ear hearing aid). Rather, the acoustically unproblematic placement of a transmitting coil in the auditory canal is sufficient for generating a magnetic field. For a completely open, occlusion-free coupling to the ear canal 1 is possible. It combines the benefits of a comfortable open BTE hearing aid with the good sound quality of the deep-seated CICs.
