Definitions

  • the invention relates to a hearing aid and a method for its production.
  • Such hearing aids are commonly referred to as HdO (behind the ear) hearing aids.
  • HdO whet the ear
  • amplifier and speaker are arranged, wherein a sound tube from the speaker via the incisura anterior is guided into the ear canal.
  • the quality of the transmitted sound signals deteriorates.
  • the transitions with different cross sections provided on the way from the listener to the ear can continue to lead to diffractions, reflections and tube resonances.
  • the sound tube which is generally made of rubber, hardens over time and becomes brittle, so it has to be replaced more often.
  • IdO hearing aids In the case of IdO hearing aids, an earmold and a housing with microphone, amplifier, operating elements, loudspeakers and battery are mounted inside the concha or in the auditory canal. They are thus well positioned to initiate sound and do not readily allow outsiders to recognize that the user is wearing a hearing aid. Due to the limited dimensions, however, the gain is limited. Furthermore, the operation of the controls is difficult because of the small dimensions, especially for older people. Such an ITE hearing aid is shown in EP 0 241 594 A1.
  • EP 0 695 108 B1 shows a hearing aid with a BTE part, a receiver part and a tubular, flexible bending element connecting them, which allows flexing in all directions and is designed such that the respectively set shape is maintained.
  • the amplifier and a battery are provided in the BTE part.
  • the microphone, actuators and the speaker or listener are provided in a receiver part, which is placed in the concha of the outer ear.
  • Through the bending element in this case run electrical lines from the microphone to the amplifier and back to the listener. This makes it possible that the hearing part pressure-free attached to the outer ear and adapted to the particular anatomical conditions of the user. Since the amplifier is provided with battery in the BTE part, they can be made sufficiently large and powerful.
  • the hearing aid Bruckhoff freestyle which is listed in Hörakustik 12/2002, page 28, has a BTE part with a microphone, amplifier, battery and operating elements in its housing.
  • the handset is mechanically housed in a housing which is connected via a rigid, shape-retaining bending element of twisted individual wires with plastic coating, and serves for direct use in the ear canal of the user. As a result, a direct sound introduction into the ear canal is possible.
  • Actuators for adjusting the hearing aid are provided in the BTE part. It is thus possible with good positioning a sufficient amplifier performance.
  • the production is complicated and expensive, so that a broad use of this system was not possible.
  • the connection of the receiver part to the bending element is difficult. Since the bending element is optionally exposed to a plurality of bending operations and at a bend by 90 ° and more at the connection of the individual wires on the receiver part high forces and moments occur, the connection of the individual wires can tear off. For a secure connection, therefore, the individual wires are folded by 90 ° in a cable guide of the listener part in the transverse direction extending transverse bolt, cut to length and incorporated in adhesive.
  • such a production is only possible manually and very expensive due to the small size and the required precision work.
  • DE 298 01 567 U1 describes a behind the ear portable hearing aid device, which has a behind the ear portable housing part and an earmold.
  • the housing part and the earmold are connected by a flexible mounting bracket.
  • the carrying handle length is selectable.
  • DE 198 58 399 C2 describes an electroacoustic transducer for hearing aids for airborne sound radiation in the external auditory canal, in which a transducer is housed in an earmold.
  • a hearing aid housing that can be worn behind the ear is connected to the earmold via a lead piece.
  • the invention has for its object to provide a hearing aid and a method for its production, which allow high strength at low cost and automated production.
  • the guide wires of the bending element are laser-welded on their outer circumference to the cable guide of the receiver part.
  • the welding is preferably carried out on the inner circumference of an output bore, through which the free ends of the guide wires are guided, preferably at the transition of the bore to an end face of the cable guide.
  • the guidewires and electrical lines in the output bore are adhesively bonded together by adhesive and with the inner periphery of the output bore.
  • the laser welding points of at least some of the guidewires ensure sufficient tensile strength against withdrawal of the wires or the bending element from the earpiece part, and the uniform bonding and fastening of the guidewires in the starting bore is achieved by the adhesive connection.
  • the flexure can be stripped at its end so that the guide wires are exposed and optionally shortened.
  • the bending element is advantageously first pre-bent in a basic shape and then set directly to stop in an input bore of the cable guide, so that the guide wires protrude through an aligned with this output hole.
  • the laser welding can be fully automated, whereupon fully automatically the adhesive is placed in the output bore between the electrical leads and guidewires.
  • the at least one electrical line which is guided by the bending element can be contacted with a speaker insert, which is accommodated in a housing sleeve or receiver sleeve, which is screwed with its internal thread on an external thread of the cable guide ,
  • a hearing aid 1 has a BTE part 2 placed behind the outer ear 15 of a user, a Biegeelement 3 extending from the BTE part 2 and an earpiece 4 attached to the other end of the Biegeiatas 3, in or on the outer ear 15th the user is positioned.
  • the BTE part 2 has a BTE case 5 and in the BTE case 5 - schematically indicated - a microphone 6 and an amplifier 7 for receiving the signals output from the microphone 6, amplifying and outputting electrical signals S to at least one electrical Line 9 on. Furthermore, 5 controls 11 are provided on the BTE case.
  • the bending element 3 is plastically deformable and restoring force-free in the set positions.
  • it has several, according to the embodiment shown seven wires, namely four guide wires 8 with a diameter of e.g. each 0.2 to 0.8 mm and three electrical lines 9 for the output from the amplifier 7 signals S, which are twisted together about the longitudinal axis of the bending element 3.
  • a middle guidewire 8b forms a neutral phase around which the other wires 8, 9 are twisted.
  • the electrical leads 9 are advantageously formed as a wire bundle; basically, a wire bundle with several, e.g. three strands as electrical line.
  • the guidewires 8 and the electrical lead 9 are embedded in a plastic sheath 10 which is made by overmoulding the guidewires 8 and the electrical leads 9 with plastic.
  • the earpiece 4 has a cable guide 12 set on the end of the bending element 3 with an external thread 13, a loudspeaker insert 14 contacted with the electrical leads 9 and a housing sleeve 16 with its internal thread 17 on the external thread 13 of the cable guide 12 is screwed and the speaker insert 14 receives.
  • the loudspeaker insert 14 can also be fastened in the housing sleeve 16 or be formed rigidly therewith.
  • the bending element 3 is stripped at its end, wherein the guide wires 8 are cut to free ends 8a.
  • the cable guide 12 has a larger diameter input bore 20a that aligns with a smaller diameter output bore 20b.
  • the end of the bending element 3 is inserted into the input hole 20a so that the plastic sleeve 10 rests against the bottom of the input hole 20a and the electric wires 9 and the guide wires 8 protrude with their free ends 8a through the output hole 20b.
  • laser welding connections 22 are preferably formed between the free ends 8a and an edge region of the inner circumference of the output bore 20b and a forward-facing, output-side end face 23 of the cable guide 12.
  • an adhesive 24 e.g. an acrylic adhesive, so that the ends 8a are bonded to each other and to the cable guide 12.
  • the bending element 3 is - unlike in the schematic representation of FIG. 2 shown - pre-bent in a curved basic shape.
  • the attachment of the bending element 3 to the cable guide 12 takes place by stripping its end and the ends 8a are cut to length.
  • the end of the flexure 3 is inserted into the input bore 20a of the cable guide 12, the ends 8a of the guide wires 8 are laser welded to the inner periphery of the output bore 20b and the edge portion between the inner circumference of the output bore 20b and the end surface 23, respectively ,
  • the following will be the electrical leads 9 with the speaker insert 14 contacted.
  • the housing sleeve 16 is screwed onto the cable guide 12.
