  • the acoustic signal is conducted by means of a sound tube from a loudspeaker or earpiece to an ear piece.
  • the speaker is not mounted in the hearing aid unit, but in the ear piece. Such a speaker is directly connected to the ear piece and is introduced together with this in the ear canal.
  • connection between the ear piece on the one hand and the sound tube or the in-ear speaker on the other hand two aspects are particularly important.
  • the ear piece must be tight enough so that it can be pulled out of the ear canal together with the sound tube or the in-ear loudspeaker.
  • the ear piece must also be able to be easily detached by a user, to clean the earpiece.
  • a connection that meets these two criteria is referred to herein as a connectable connection.
  • an earpiece by means of a snap connection with a sound tube or an in-ear speaker.
  • the ear piece is then shaped so that e.g. can be pushed onto a connecting element of a sound tube and locked there.
  • a connecting element e.g. an inflatable in-ear balloon
  • a connecting element e.g. an inflatable in-ear balloon
  • a pressure channel from a pump must be directed to a volume changeable element, such as the in-ear balloon of the earpiece, to inflate it with air or other medium.
  • the pump may be arranged in the hearing aid unit or at an ear-side end of the sound tube. It is also possible to place the pump in the earpiece itself.
  • the pump used may be a conventional loudspeaker used in hearing aids, a so-called receiver.
  • a problem with such designs is the sealing of the pressure channel at a coupling connection between the sound tube and earpiece.
  • a hearing device for a hearing aid unit comprising a sound tube with a hose-side coupling element, and an ear piece with a ear piece-side coupling element.
  • the hose-side coupling element and the earpiece-side coupling element are preferably non-positively and / or positively coupled and decoupled.

  • the pressure element can be integrated in the hose-side coupling element or in the ear piece-side coupling element, depending on whether it is designed as a clamping pressure element or Sp Son horrelement, ie for generating pressing pressure.
  • one of the coupling elements may itself be a pressure element or have the function of the pressure element.
  • the pressure channel can be any kind of opening, even small holes, grooves or punched-out sections, through which air, another gas or a fluid can flow.
  • the sound tube is also a pressure channel according to this definition, but separated from the actual pressure channel and basically provided for the sound propagation.
  • the pressure channel is preferably provided for supplying and discharging pumped air.
  • the hose-side pressure channel in the form of at least two merging holes executed. Two cylindrical holes merge into each other at any predetermined angle so that they connect to form a channel. The transition of the holes allows the use of the angle selection different curves or bends of the pressure channel.
  • the earpiece-side pressure channel is at least partially designed by means of a circumferential groove.
  • a circumferential groove In a largely radially symmetrical earpiece, which is to be flexibly rotatably coupled to the sound tube, this represents an elegant solution.
  • the circumferential groove At the sound tube while a hole from the hose side pressure channel is provided, which corresponds in the coupled state with the circumferential groove of the earpiece side pressure channel.
  • the circumferential groove may be formed as part of a coupled pressure channel, e.g. Air pressure, be applied.
  • a coupled pressure channel e.g. Air pressure
  • one or more bores can now have the circumferential groove with a further section, e.g. connect to an in-ear balloon. Consequently, this in-ear balloon can be supplied with pressure through the pressure channel in each rotational position of the ear piece on the coupled sound tube.
  • the sound tube and the ear piece each have a sound channel, which is separated from the respective pressure channels acoustically and airtight. Thus, there is no mutual influence.
  • the hose-side coupling element and the earpiece-side coupling element can be coupled by means of a Luer or a Luer-Lock connection. This is a proven and widespread coupling technology in medical technology.
  • the hose-side coupling element and / or the earpiece-side coupling element itself have an additional function as a pressure element.
  • both coupling elements are sleeve-shaped or tubular and adapted to each other so that, for example, the earpiece-side coupling element can be pushed onto the hose-side coupling element.
  • the tolerances of the dimensions are selected to each other so that a contact pressure of the coupling elements to each other in the coupled state. In this way, the coupling elements are non-positively connected.
  • the earpiece-side coupling element presses on the hose-side coupling element, so that a relative slippage of the coupling elements to each other is possible only by external force.
  • at least one of the coupling elements additionally acts as a pressure element on the other coupling element. This improves an air seal in the area of the coupled pressure channel.
  • the hose-side coupling element and the earpiece-side coupling element are positively coupled by means of a clip connection.
  • Such clip connections provide that one of the coupling elements has a groove in which a protruding resilient portion of the other coupling element can hook.
  • the clipping of the resilient portion and the associated entanglement prevents lateral slippage of the coupling elements relative to each other. Due to the fact that the resilient portion also presses against the earpiece-side coupling element due to its resilient action, an improved sealing of the coupled pressure channel is additionally provided.
  • the hose piece-side coupling element thus has an additional function as a pressure element.
  • FIG. 1 an embodiment of a hearing aid unit 2 with a hearing device 4 is shown.
  • a sound tube 6 leads from the hearing aid unit 2 to a hose-side coupling element 8.
  • An ear piece 10 comprising, inter alia, an ear piece-side coupling element 12 is reversibly coupled to the hose-side coupling element 8.
  • Reversibly coupled means that, for example, a clamping or plug connection is provided, which can be connected and disconnected as desired. Most such compounds are non-positively and / or positively designed.
  • the coupling is shown by means of a plug-in mechanism with a barb. This represents only one of many coupling options, such as a bayonet, a screw, a Luer connection, a clip closure or the like.
  • the coupling mechanism is designed such that a user can perform the coupling and decoupling independently by hand.
  • a hose-side pressure channel 16 and a ear piece-side pressure channel 18 are integrated in each case. These two pressure channels have openings in the coupling area, which are at least partially corresponding to one another there. In this way, the hose-side coupling element 8 and the ear-piece-side coupling element 12 during coupling form a coupled pressure channel 20, not shown here.
  • a volume changeable element 14 is attached at the earpiece 10.
  • it has the design of a balloon or in-ear balloon. It is in direct contact with an opening of the earpiece-side pressure channel 18.
  • the volume of the volume-changeable element 14 can be influenced in the coupled state.
  • the pumping system 22 may be integrated in the hearing aid unit 2 and connected from there to the hose-side pressure channel 20. Alternatively, the pumping system 22 may also be arranged directly in or in the vicinity of the hose-side coupling element 8.
  • the pumping system 22 conveys a medium such as air or other gas along one of the two directions of travel of the coupled pressure channel 20. This causes the volume-changeable element 14 in contact therewith to inflate or collapse.
  • the volume may be affected to the extent that this allows limits such as the maximum extensibility of the material used or the thickness of an ear canal into which it can be inserted.
  • a pressure element 24 is used.
  • this is a metal ring which is integrated in the earpiece 10 and which causes a certain clamping force.
  • the strength of the compressive force or clamping force depends on the material and the dimensioning of the pressure element 24.
  • the coupled pressure channel 20 is generated.
  • the coupling point is not quite airtight.
  • a medium pumped by the pumping system 22 could escape unintentionally at this point.
  • the pressure element 24 clamps the two coupling elements, and thus also the coupling point of the coupled pressure channel 20, together more strongly than would the coupling elements alone. This leads to an improved sealing of the coupled pressure channel 20.
  • the tightness of the coupling point of the coupled pressure channel 20 may depend, inter alia, on the choice of material of the earpiece-side coupling element 12 and the slip-side coupling element 8. Softer surface materials such as rubber or plastics can better seal this coupling than harder surface materials such as metals. In addition, a minimal surface smoothness is beneficial.
  • FIG. 2 an alternative embodiment of the hearing device 4 is shown in a coupled state outlined.
  • the coupling takes place by means of a force and form fit, which comes about due to the structural design of the hose-side coupling element 8 and the earpiece-side coupling element 12.
  • the two coupling elements hooked as shown.
  • the ear piece side coupling member 12 presses the hose side Coupling element 8 clamped together.
  • This clamping force is amplified by the pressure element 24.
  • the pressure element 24 is incorporated as a clamping metal ring in the earpiece 10.
  • the coupled pressure channel 20 which is composed of the hose side pressure channel 16 and the ear piece side pressure channel 18, supported and improved.
  • the coupled pressure channel 20 is structurally separated from a sound channel 26.
  • the earpiece-side pressure channel 18 comprises a circumferential groove 32 and at least one bore 34, which connects the circumferential groove 32 with the inner region of the volume-changeable element 14.
  • the hose-side coupling element 16 is formed from at least two components, an inner component 36 and an outer component 38. These components can be glued together, for example. But other connection options are possible.
  • a portion of the hose-side pressure channel 16 can be created by the structural composition of the components, without this pressure channel section is to be incorporated separately by means of an additional hole.
  • At least one bore 40 for the connection of all pressure channel sections is provided on the outer component 38.
  • the inner member 36 is made of a metal, such as brass.
  • a bore of the sound channel 26 may have a smaller diameter and the thickness of the wall may be smaller than with a less stable material than metal.
  • the outer member 38 is made of a plastic material such as a rubber. Thus, it can well seal the coupling of the coupled pressure channel 20, since it is a material with a relatively soft surface.
  • the earpiece 10 can be largely made radially symmetrical. It is thus freely rotatable about the hose-side coupling element 8 during the coupled state, and a continuously uninterrupted, coupled pressure passage 20 extending from the pumping system 22 to the volume-changeable element 14 is ensured.
  • the Fig. 3 mainly shows alternative embodiments of the printing element 24.
  • the pressure element 24 is shown once as a compression spring in the sound channel 26 and once as a spreader ring on the hose-side coupling element 8. Both variants generate a spreading pressure on the hose-side coupling element 8, which engages in a coupled state on the earpiece-side coupling element 12 and thus supports the sealing of the coupled pressure channel 20.
  • FIG. 4 The perspective sectional sketch of Fig. 4 shows a further embodiment of the hearing 4.
  • the earpiece side coupling element 12 the circumferential groove 32 and the bore 34, the earpiece side pressure channel 18. This communicates with the hose side pressure channel 16 and forms with this the coupled pressure channel 20.
  • the pumping system 22 can be supplied by the coupled pressure channel 20, the volume changeable element 14 in the form of an inflatable balloon with pressure.
  • the pumping system 22 may apply pressure from the volume changeable element 14, thereby reducing its volume and shrinking it.
  • An overhang 40 is provided to prevent the volume changeable element 14 from becoming caught in the bore 34 and possibly clogging it.
  • the overhang 40 is attached as a kind of protective shield to the earpiece-side coupling element 12 and projects beyond the bore 34. Visually and functionally, it resembles a dome as used in many hearing aid devices.
  • the overhang 40 can intercept a collapsible volume changeable element 14, that it does not clog the coupled pressure channel 20.
  • Another advantage is that the uninflated volume changeable element 14 is held by the overhang 40 in a form that makes it easier to inflate.
  • the approach of the overhang 40 on the earpiece-side coupling element 12 also forms a trough in which the pressure element 24, here in the form of a clamping ring, can be placed locally.
  • the trough protects the clamping ring from slipping.
  • the Fig. 5 shows a further alternative embodiment of a hearing device 4.
  • the hose-side coupling element 8 and / or the earpiece-side coupling element 12 itself have an additional function as a pressure element 48. This assists an air seal of the coupled pressure channel 20.

  • the hose piece-side coupling element 8 thus has an additional function as a pressure element.
  • Fig. 7 and 8th is the operation of the coupling between the hose-side coupling element 8 and earpiece-side coupling element 12 of the embodiment Fig. 6 shown schematically.
  • the sketches show as in Fig. 7 First, the hose-side coupling element 8 is guided in the direction of earpiece-side coupling element 12. The direction is represented by the arrow 50.
  • the resilient portion 44 When inserting the hose-side coupling element 8 in the earpiece-side coupling element 12, the resilient portion 44 is compressed until the front region reaches the groove 42, in which it engages and thus forms the clip connection 46. After snapping, as in Fig. 6 shown, the resilient portion 44 springs against the earpiece-side coupling element 12, so that he presses against it. A region of the hose-side coupling element 8 thus serves as a pressure element 48. In this way, a seal of the coupled air duct 20 is improved.
