Definitions

  • Hearing aids with external handset or hearing aids with rechargeable energy storage (for example) battery is growing in the number of external electrical connections.
  • these external connectors of hearing aids are made as externally accessible electrical contacts made of gold-plated metal.
  • the complexity and cost of these hearing aids increase significantly with an increasing number of ports.
  • One example is the numerous variants of audio inputs, programming connections and charging contacts for commercially available hearing aids.
  • the document DE 94 08 054 discloses a hearing aid with parts of electrically conductive and at the same time sound insulating material, which are used simultaneously as a sound-absorbing elements of the construction of the hearing aid, its housing or its components and as electromagnetic shielding of the parts.
  • the present invention seeks to improve this situation.
  • electrical contacts made of electrically conductive and simultaneously sound-absorbing material without additional metal parts on the outside of a hearing aid housing.
  • the invention leads to a hearing aid with parts of electrically conductive and at the same time sound-absorbing material, which are used simultaneously as sound-insulating elements of the construction of the hearing aid, its housing or its components and as electrical contacts.
  • the hearing aid is equipped with parts of electrically conductive and at the same time elastic material, in particular with parts made of an elastic natural or plastic, which were admixed with electrically conductive particles during processing.
  • the hearing device is equipped with parts made of electrically conductive and at the same time sound-insulating material to which pigments have been mixed during processing which contribute to the optical inconspicuousness of these parts in relation to their surroundings.
  • sound-insulating is to be understood as meaning an acoustic, sealed connection based primarily on shock-absorbing and / or vibration-inhibiting properties.
  • a hearing aid with parts of electrically conductive and at the same time sound-insulating material, which serve as a storage for components of the hearing aid, which should be acoustically shielded against sound transmission through these parts.
  • the transducer bearings currently made of various rubbery materials, e.g. Silicone and currently meet mainly acoustic requirements - for example, in terms of sound insulation - meet.
  • Transducers in this context are mainly listeners or microphones.
  • the present invention now provides, in one of its embodiments, for producing these bearings-for example, transducer bearings of electrically conductive and at the same time sound-insulating material-of electrically conductive material (for example of conductive rubber) and thus to provide an electrical contact on the outside of a hearing aid. on top of that, not even as Such would be perceived and thus would represent a more cosmetically pleasing variant of an electrical contact.
  • the combination of these two properties of electrical conductivity and sound insulation can be achieved for example by an admixture of conductive particles or by vulcanizing metallic body or by subsequent external metallization, for example by vapor deposition.
  • the converter housings are often already electrically connected to the actual amplifier circuit (e.g., the microphone housings are largely grounded), even the extra connection from the externally accessible contact to the circuit board is eliminated. Because because the metal housing of the converter is already electrically on the reference potential ("ground” or GND) and the conductive elastic mass now also touches the housing, is on the outside of a conductive contact alone by the visible storage available.
  • ground reference potential
  • connector Another already existing component that has not previously been used as an electrical contact is the so-called connector. This is in most cases made of metal. At this so-called support hook is screwed or plugged in so-called "behind-the-ear hearing aids".
  • an embodiment of the invention provides to use this component as an electrical contact - for example, to external transducers or external switches.
  • the internal connection to the hearing aid amplifier can in turn be made via electrically conductive earphone mounts or in this case by direct connection of an electrical line (2.B. soldering, welding, clamping, gluing ...)
  • the present invention thus has a number of advantages.
  • Figure 1 shows a possible embodiment of the invention in a schematic manner. Due to the corresponding structure of a hearing aid, it would be possible, for example, to automatically detect the presence of a particular carrying hook.
  • the external "switching element" (A) acts as electrical contact between the conductive microphone mounting (B) and the metal connection piece (C).
