Definitions

  • the invention relates to a receiver tube with integrated strain relief for a hearing aid and a hearing aid with such a receiver tube.
  • Hearing aids are used to treat hearing impaired, hard of hearing patients. They consist principally of a microphone as a sound pick-up for recording ambient sound, of a signal processing device and amplification, and of a loudspeaker, also called a receiver or a receiver.
  • the term receiver means any output signal generator of a hearing aid. The receiver generates recorded by the hearing aid and processed acoustic output signals that are routed to the patient's hearing.
  • a hearing aid In addition to hearing aids for generating amplified auditory signals to the hearing-impaired, which serve to compensate for a weakened hearing, commonly referred to as deafness, other devices may be termed a hearing aid, e.g. so-called tinnitus maskers. Tinnitus maskers are used to treat tinnitus patients. They produce from the respective hearing impairment and depending on the principle of action also dependent on ambient noise acoustic output signals that can contribute to reducing the perception of annoying tinnitus or other ear noises. In the following, the term hearing aid also tinnitus maskers and other such devices are understood.
  • IDO hearing aids in-the-ear, in-the-ear
  • IDO hearing aids is a housing that contains all the functional components including microphone and receiver, mostly worn in the ear canal.
  • CIC hearing aids are similar to IDO hearing aids, but are fully integrated with the Ear canal worn.
  • a housing with components such as battery and signal processing device behind the ear is worn and a flexible tube, also referred to as tube, directs the acoustic output signals of a receiver from the housing to the ear canal
  • RIC-BTE hearing aids receiver-in-canal behind-the-ear
  • the receiver is carried in the ear canal and the flexible tube instead of acoustic signals electrical signals to Reiceiver, which is mounted on the front of the tube.
  • the receiver in the ear canal is fixed by a so-called Eartipp, depending on the version.
  • the Eartipp can be made of a soft and therefore comfortable to wear, flexible material, such as silicone. It is elastic and shaped so that it is supported by the elastic forces against the hearing. This results in a positive connection of Eartipp and auditory canal, which cause a stable positioning in the ear canal and can prevent accidental slipping out of the ear canal.
  • the receiver is located in the area of the Eartipp and is positioned by this stable in the ear canal.
  • the elastic forces of the Eartipps which may have a dome-shaped contour and therefore also referred to as a dome must be sufficiently large for this purpose.
  • the receiver is occasionally removed from the ear canal, eg for cleaning, replacement or when the hearing aid is not intended to be worn.
  • the removal is usually done in the simplest way by pulling on the tube.
  • the tensile force must be sufficiently large to overcome the force with which the Eartipp receiver tube and receiver fixed in the ear canal. Occasionally, the Eartipp is replaced, for which it is deducted from the tube. Due to such tensile forces, the flexible earphone tube is stretched, more specifically lengthened. This longitudinal stretching can possibly up to several millimeters be. Once the tensile forces are turned off, the receiver tube reversibly returns to its original length.
  • a problem with the longitudinal extension of the flexible material consisting of the listener tube is that extending in the listener hose electrical conductor that connects the BTE housing to the receiver, usually consists of a less stretchable metal.
  • the considerably greater longitudinal expansion of the receiver tube compared to this conductor results in high tensile forces being able to occur between the conductor and the receiver attached to the receiver tube and connected to the conductor. And even with a much more extensible conductor high tensile forces would occur at the connection to the receiver. Due to these tensile forces, the conductor can in the worst case be torn off the receiver.
  • a BTE hearing aid in which a length adjustment of the listener tube is thereby possible that an optionally excess longitudinal section of the listener tube is disposed within the housing.
  • the longitudinal section is wound around a spindle, which may be biased by a spring depending on the design.
  • This construction requires a relatively high space requirement in the BTE housing and is also mechanically complex.
  • the electrical conductor running in the listener hose can have an expansion reserve in which it is laid spirally around a flexible carrier core.
  • the carrier core is longitudinally expandable due to its flexibility, the conductor due to its spiral winding.
  • Such a conductor, including the carrier core is complicated to manufacture and also has a relatively large diameter, which runs counter to the cosmetically desirable reduction of the receiver tube.
  • such a conductor in the form of the additional flexible carrier core has an additional material core, which runs counter to the likewise cosmetically desirable increase in the optical transparency of the hearing tube and reduces the overall flexibility of the receiver tube in an undesired manner.
  • the object of the invention is to provide a receiver tube with a strain relief and a hearing aid with such a receiver tube, wherein the pulling aid is inexpensive to manufacture and favors a small diameter, high optical transparency and high flexibility of the receiver tube.
  • the invention solves this problem by a Hörerschlauch and by a hearing aid with the features of the independent claims.
  • a basic idea of the invention resides in a hearing aid tube for a hearing aid, comprising a flexible covering and an electrical conductor running through the covering, longitudinally displaceable relative to the covering, wherein in the absence of tensile load in the longitudinal direction a longitudinal section of the conductor located within the covering has a greater length as the longitudinal portion of the sheath surrounding it, and wherein this longitudinal portion of the conductor is freely movable within the longitudinal portion of the sheath transverse to the longitudinal direction.
  • the greater length of the conductor compared to the sheath can compensate for a longitudinal extension of the sheath under tensile loading, since the conductor in the sheath is longitudinally displaceable.
  • a tensile load of the connection of the conductor with a connected receiver or with electronic components of signal processing in the housing of a hearing aid can be avoided.
  • a simple, inexpensive, optically transparent and mechanically flexible construction is ensured, since no additional, disadvantageously acting components, such as e.g. a spindle or a carrier core are required.
  • the length of the conductor can be several millimeters larger.
  • the difference in length between the conductor and the envelope is chosen so that, up to a predetermined maximum tensile force, the longitudinal extent of the envelope is less than said difference in length.
  • the difference in length is thus selected so that the length of the casing is by no means greater than the length of the conductor up to the predetermined maximum tensile force.
  • a suitable maximum tensile force in view of the use in hearing aids is 10 N or less, in particular 5 N.
  • the cross-sectional area and the modulus of elasticity of the sheath must be suitably chosen.
  • it is advantageous if the longitudinal expansion of the envelope remains up to the desired maximum tensile force in the linear elastic range.
  • the longitudinal section of the conductor is corrugated or preformed in a spiral shape.
  • a uniform preforming of the conductor is given, which also ensures flexible extensibility in the longitudinal direction and can be visually appealing.
  • such a preforming ensures the greatest possible flexibility and facilitates the insertion of the conductor together with excess length in the enclosure during assembly.
  • the diameter of the lumen of the longitudinal section of the envelope corresponds to twice to three times the diameter of the conductor. This is an excellent compromise in terms of unrestricted freedom of movement, especially in the transverse direction of the inboard conductor and the smallest possible overall diameter of the Hörerschlauchs given. This increases a larger lumen the freedom of movement of the conductor and thus the flexibility, while facilitating the assembly. A larger overall diameter, however, reduces the overall flexibility and is visually more conspicuous and thus undesirable from a cosmetic point of view.
  • a further advantageous development of the basic idea is that the longitudinal section of the envelope extends over the entire length of the envelope.
  • an envelope can be used which has a constant cross-section over its entire length.
  • Such a casing is less expensive to produce than a casing with alternating cross-sections, in which the longitudinal section extends only over a partial length region of the casing.
  • it can be customized in the long run without further ado by being cut to a suitable length as well as so-called yard goods.
  • a further advantageous development of the basic idea is that with tensile load in the longitudinal direction both the envelope of the tube as well as the longitudinal section of the conductor lying within the envelope can be reversibly lengthened. As a result, tensile forces on the electrical connection points of the conductor, eg with a receiver or hearing aid housing, prevented. By the reversible regression after switching off the tensile forces at the same time a high flexibility in use is ensured by the original and possibly adapted to the respective hearing aid wearer tube length is taken again.
  • a further advantageous development of the basic concept consists in that a releasable electrical connector for connection to a hearing aid housing or to a receiver is provided at at least one end of the receiver tube.
  • the receiver can be replaced or replaced without the need for a new tube or even a new hearing aid housing.
  • Another basic idea of the invention consists in a hearing aid with a previously trained earphone tube.
  • the hearing aid comprises a housing which is adapted to be worn behind a pinna of a hearing aid wearer, and a receiver which is adapted to be carried in the ear canal of the hearing aid wearer, wherein the listener tube the Receiver and the housing connects.
  • a RIC-BTE hearing aid This is realized as a particularly advantageous application, a RIC-BTE hearing aid.
  • FIG. 1 a prior art RIC-BTE hearing aid 1 is shown schematically.
  • a battery 10 which supplies the electrical components with energy.
  • the battery can be both rechargeable and non-rechargeable and relies on conventional battery technology, e.g. Zinc-air, nickel-metal-hydride, lithium-ion, lithium-polymer etc.
  • a signal processing 11 is used to process acoustic input signals. It can work analog or preferably digitally and be based as a core piece on a generally available or individually adapted computing unit.
  • the signal processing 11 is used to generate suitable acoustic output signals of the hearing aid 1 as a function of a selectable hearing program and optionally of an acoustic input signal source.
  • an operation independent of acoustic input signals could also be considered.
  • Microphones 12 receive ambient sound and convert it into input signals for the signal processing device 11.
  • the microphones 12 are based on conventional microphone technology. Although two microphones 12 are preferably provided in order to enable as advantageous a signal processing as possible with a good signal-to-noise ratio and good spatial signal resolution, a single microphone 12 or a larger number may instead be provided.
  • the output signals of the signal processing device 11 are supplied to a receiver 14 by an electrical conductor 13.
  • the conductor 13 passes through the connector 3 and the tube 6.
  • the receiver tube 6 comprises a flexible envelope 4, which is usually designed with a small diameter and made of transparent plastic.
  • the receiver 14 is arranged on the end remote from the housing 2 of the receiver tube 6. He is in an ear piece, in this case designed as a dome 5 mounted.
  • the dome 5 is exchangeably mounted on the tube 6. It is worn during normal operation of the hearing aid 1 in the ear canal it Hör Anlagenmikmiks. To pull the dome 5 out of the ear canal, the hearing aid wearer usually simply pulls on the tube 6, as well as to separate the dome 5 from the tube 6. Due to its flexible design, the tensile load acting in the longitudinal direction of the receiver tube 6 results in a considerable longitudinal expansion of the receiver tube 6. This longitudinal expansion in turn can lead to a tensile load on the connection between the conductor 13 and the receiver 14 and the connection between the conductor 13 and the housing 2 lead the conductor 13 connected components.
  • the handset tube 27 comprises a wrapper 24 made of flexible material.
  • the wrapper may be made of a conventional material, e.g. made of transparent plastic.
  • the conductor 26 connects the receiver 28 to the housing 22 and the electronic components arranged therein.
  • the invention relates to a receiver tube with integrated strain relief for a hearing aid and a hearing aid with such a receiver tube.
  • a receiver attached to the end of the receiver tube is usually carried in the ear canal of a hearing aid wearer. It is pulled out of the ear canal by pulling on the tube or is disconnected from the tube for cleaning or replacement. Due to the tensile forces of the flexible earphone tube is stretched, more precisely, drawn in the length. This longitudinal extension may be up to several millimeters under certain circumstances and load or even damage the connection of the less extensible conductor running through the receiver tube with the receiver or with the hearing aid.
