Definitions

  • the invention relates to a hearing device with an acoustic unit and a shell part, in which the acoustic unit can be inserted.
  • hearing device is understood in particular to mean a hearing device.
  • the term includes other portable acoustic devices such as headsets, headphones and the like.
  • 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 shown using the example of a behind-the-ear hearing aid. 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 also 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
  • the electronic components of a hearing aid are often installed in a frame that fixes them in their position.
  • a frame populated with electronic components forms the acoustic unit of a hearing aid.
  • This is installed in a housing which is usually formed two shells. For service purposes or to be able to combine different housing parts in color and / or shape, it is expedient to assemble and disassemble the corresponding parts easily and quickly.
  • the parts of a hearing aid are screwed together or fixed with at least two pins. Screws or pins have an adverse effect on the visual appearance of a hearing aid, since they interrupt the closed nature of the outer surface and usually stand out clearly in color. In addition, pins that have slightly different lengths due to the design, can be reversed, which also negatively affects the appearance and comfort.
  • the object of the present invention is to provide a hearing device in which a shuttering can be replaced easily, quickly and with as few additional parts as possible.
  • the hearing device comprises an acoustic unit and a shell part, in which the acoustic unit is inserted, wherein the acoustic unit has a projection which engages in the inserted state of the acoustic unit in a correspondingly shaped portion of the shell part, and wherein by the intervention movement of the acoustic unit in a direction is blocked out of the shell part.
  • the hearing device has the advantage that the acoustic unit in the inserted state is already prevented by the projection on the acoustic unit from moving in the shell part in the direction indicated. This setting of the acoustic unit with respect to the direction of movement from the shell happens automatically when inserting. It must therefore be time-consuming inserted into an opening of the shell part so no pen.
  • the shell part does not have to form a complete shell of the hearing device.
  • the complete shell can also consist of several parts.
  • the shell part preferably forms the predominant part of the complete shell, so that correspondingly also a predominant part of the acoustic unit is surrounded by the shell part, when the acoustic unit is inserted in the same.
  • the projection of the acoustic unit is brought by a combined pivot-slide movement so engaged with the correspondingly shaped portion of the shell part in that the acoustic unit can then not be lifted directly out of the shell part.
  • the correspondingly shaped region thus forms, viewed from the opening of the shell part, an undercut whose shape preferably corresponds to the shape of the projection.
  • the projection engages in this undercut.
  • the acoustic unit is thus hooked in the area by means of the projection.
  • the hearing device is developed in an advantageous manner, when the acoustic unit in the inserted state has exactly one degree of freedom of movement with respect to the shell part.
  • An acoustic unit which is inserted in a shell part, has a total of six possible degrees of freedom of movement. It could translate in three different spatial directions and additionally perform three rotational movements around mutually perpendicular axes. Rotational movements also include tilting the acoustic unit when, for example, the acoustic unit is first grasped and lifted at one end for removal from the shell portion and then lifted to subsequently withdraw the other end from the shell portion.
  • the acoustic unit By restricting the possibility of movement of the acoustic unit in the shell part to a degree of freedom of movement, there is the advantage that the acoustic unit can then be attached with very simple means in the shell part, that the acoustic unit and the shell part are finally immovable to each other.
  • the movement permitted by the remaining degree of freedom is a rotation about an axis of rotation determined by the projection.
  • Such a pivoting or tilting movement makes it possible to insert the acoustic unit in the shell part or to remove it again, without the acoustic unit thereby tilted in the shell part.
  • the acoustic unit is engaged in the inserted state in the shell part. This facilitates handling of the shell part with an acoustic unit inserted therein during assembly of the hearing device.
  • the hearing device is further developed if the projection is formed by a step in an outer wall of the acoustic unit.
  • a level can be with little Training expenses, for example, on a frame of the acoustic unit.
  • the foot has a further projection of the said type and the shell part corresponding to a further region of said type and the foot is arranged in the inserted state of the acoustic unit between the two regions.
  • the acoustic unit can be fastened in the inserted state by inserting a pin in the shell part such that the acoustic unit and the shell part are immovable relative to one another.
  • the pin preferably penetrates both the acoustic unit and at least one wall of the shell part.
  • the pin in the inserted state forms an axis of a hinge for a battery compartment of the hearing. This makes it possible to connect by inserting a single pin, so by a single handle, three components of the hearing with each other.
  • an advantageous development of the hearing device according to the invention results from an additional positional fixation of the acoustic unit in the shell part by a positive connection.
  • This additionally restricts the freedom of movement of the acoustic unit before the pin is mounted, and thus makes work easier.
  • the positive connection is formed by ribs and grooves in the shell part and the acoustic unit, which can be generated with no additional effort in the manufacture of the parts.
  • the illustrated example represents a preferred embodiment of the invention.
  • FIG. 2 an acoustic unit 6 and a shell part 7 are shown, which form part of an in FIG. 2 not shown hearing aid.
  • the hearing aid is built according to a changeable shell concept, ie visible parts, including the housing, are easy and quick to replace.
  • the acoustic unit 6 is inserted in the shell part 7.
  • An in FIG. 2 Upper part of the acoustic unit 6 protrudes from an opening 8 of the shell part 7 out.
  • the arrow of the reference numeral for the opening 8 points to an edge region of the opening 8 delimiting the opening 8.
  • the upper part of the acoustic unit 6 can be provided with an in FIG. 2 not shown part also be boarded.
  • the acoustic unit 6 can not be directly along a direction that in FIG. 2 is indicated by a directional arrow 9, lift out of the shell part 7.
  • a connecting piece 11 for a in FIG. 2 Support hooks, not shown, of the hearing aid are two stages 12a, 12b, which are located on two opposite sides of the connecting piece 11 is formed.
  • One of the two stages, the stage 12b, is in the representation of FIG. 2 However, hidden by the connecting piece 11 and therefore not visible.
  • the two steps 12a, 12b block movement of the acoustic unit 6 in the direction 9, because they each engage in a region 13a, 13b of a wall of the shell part 7 with respect to the direction 9.
  • the region 13b is like the step 12b in FIG FIG. 2 behind the connecting piece 11 and is therefore not visible.
  • the steps 12a and 12b engage in the regions 13a and 13b in the inserted state of the acoustic unit 6 in an undercut, which is formed in the respective region 13a, 13b in the wall of the shell part 7.
  • the foot 10 is usually made of steel or ceramic; the shell part 7, however, is made of a plastic. Therefore, the steps 12a, 12b do not use even if the shell part 7 is frequently replaced by other shell parts.
  • the acoustic unit 6 In order to lift the acoustic unit 6 out of the shell part 7, the acoustic unit 6 first has to be lifted out of the shell part in a pivoting movement whose course is illustrated by a directional arrow 14.
  • the acoustic unit 6 executes a rotation about a rotation axis 14a in the sense of the invention.
  • the foot 10 and the connecting piece 11 can be pulled away from the regions 13a, 13b of the wall of the shell part 7 by a movement of the acoustic unit 6 in a direction which is characterized by a directional arrow 15.
  • the acoustic unit 6 can be found in the in FIG. 2 shown inserted state in the shell part 7 are securely fastened by a pin 16 is inserted into an opening 17 in the shell part 7.
  • a pin 16 is inserted, it is also partially in the acoustic unit 6.
  • it also forms an axis of a hinge 18 for a battery compartment 19 of the hearing aid.
  • the acoustic unit 6 is also without the pin 16 is inserted not loose in the shell part 7.
  • An in FIG. 2 not shown locking mechanism secures the acoustic unit 6 against falling out. However, the acoustic unit 6 can be released with relatively small forces from a holder of the latching mechanism '.
  • FIG. 3 are shown again from another perspective, an area of that acoustic unit 6 and a portion of that shell part 7, in connection with FIG. 2 already described. That's why in FIG. 3 Assign reference numerals corresponding to those in FIG. 2 correspond.
  • the shell part 7 forms part of a housing of the hearing aid. It is formed at the position of the connection piece for the carrying hook such that the acoustic unit 6 fits into the shell part 7 so that only one degree of freedom remains open. This degree of freedom is blocked by a latching mechanism in the acoustic unit and the shell part.
  • the locking mechanism is designed so that the acoustic unit can be removed again.
  • the eventual securing of the acoustic unit 6 in the shell part 7 is then effected by a single pin 16, which simultaneously serves as a positional fixing of the acoustic unit 6 and as a rotation axis for the battery compartment 19.
