Definitions

  • the invention relates to a hearing instrument, in particular a BTE hearing system, with a housing and a connected by plug connection to the housing sound tube, and a sound tube with a corresponding plug and a housing with a corresponding socket.
  • Hearing instruments can be designed for example as hearing aids.
  • a hearing aid is used to supply a hearing-impaired person with acoustic ambient signals that are processed and amplified for compensation or therapy of the respective hearing impairment. It consists in principle of one or more input transducers, of a signal processing device, of an amplification device, and of an output transducer.
  • the input transducer is typically a sound receiver, e.g. a microphone, and / or an electromagnetic receiver, e.g. an induction coil.
  • the output transducer is usually as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z.
  • the output transducer generates output signals that are routed to the patient's ear and are intended to produce a hearing sensation in the patient.
  • the amplifier is usually integrated in the signal processing device.
  • the hearing aid is powered by a battery integrated into the hearing aid housing.
  • the essential components of a hearing aid are usually arranged on a printed circuit board as a circuit carrier or connected thereto.
  • Tinnitus maskers are used to treat tinnitus patients. They generate from the respective hearing impairment and depending on the principle of action also dependent on ambient noise acoustic output signals, which can contribute to reducing the perception of disturbing tinnitus or other ear noises.
  • Hearing instruments can also be designed as telephones, mobile phones, headsets, headphones, MP3 players or other telecommunications or consumer electronics systems.
  • hearing instrument is to be understood as meaning both hearing aids and tinnitus maskers, comparable such devices, as well as telecommunications and consumer electronics systems.
  • Hearing aids are known in various basic housing configurations.
  • BTE hearing aids (behind-the-ear, or behind-the-ear or HDO)
  • a housing with components such as battery and signal processing device behind the ear is worn and a flexible sound tube, also referred to as a tube or tube, passes the acoustic output signals a receiver from the housing to the ear canal, where often an ear piece is provided on the tube for reliable positioning of the tube end in the ear canal.
  • All housing configurations have in common is that as small a housing as possible be sought in order to increase the comfort and to reduce the visibility of the hearing aid for cosmetic reasons.
  • the receiver In conventional BTE hearing instruments, the receiver is held in the housing, optionally decoupled from the housing with respect to vibrations, and connected by a connector to the sound outlet of the housing. Connected to the sound output of the housing is the sound tube that directs the output signals of the receiver to the ear of the hearing instrument wearer.
  • the connecting piece can be mounted, for example, in the housing or a frame arranged in the housing.
  • a BTE hearing aid in which the receiver is located in the ear canal (also referred to as RIC-BTE hearing aid).
  • the receiver is placed in an ear piece where it is connected to a tube or sound channel.
  • the object of the invention is to provide a hearing aid with housing and sound tube that has an inexpensive, easy-to-install, dense in terms of sound, contamination and moisture density, and easily reversible closing and releasing connection of housing and tube.
  • the invention solves this problem by a hearing instrument and by a corresponding housing and a corresponding sound tube with the features of the independent claims.
  • a basic idea of the invention consists in a hearing instrument comprising a housing in which a receiver is arranged, and a sound tube for directing output signals of the receiver into an auditory canal in that a mounting insert is arranged in the housing, which has a receiver compartment and a socket, wherein in the receiver compartment of the receiver is used, and wherein the socket has a circumferential recess or elevation, that the sound tube has a plug with a corresponding with the circumferential recess or elevation of the socket survey or depression, and that socket and plug are designed such in that the plug can be reversibly inserted into the socket and pulled out.
  • the mounting insert eliminates the need for an additional sound conducting connector between the receiver and the sound tube.
  • the number of components of the hearing instrument is reduced, which has an advantageous effect on the assembly costs, the logistical effort in the provision of the hearing instrument components and the maintenance and contributes to a reduction of the hearing instrument.
  • the avoidance of a further connector has an advantageous effect on the soundproofness of the connection between the receiver and the sound tube.
  • the condition for the interchangeability of the sound tube is advantageously created. Due to the design of the socket and the plug with corresponding circumferential recesses and elevations a detent for the connector is created, which is easy to use without additional tools and is intuitively understood without further ado.
  • the plug has a matching recess in a socket survey or vice versa has a matching over a survey of the socket recess.
  • the circumferential configuration also allows rotation of the plug relative to the socket, so that the individual adaptability of the hearing instrument to the ear and head shape of the hearing instrument wearer is improved.
  • the arrangement of the mounting insert and the socket in the housing of the hearing instrument causes a not visible from the outside or barely visible placement of the connector, which is advantageous from a cosmetic point of view.
  • the mounting insert is made in one piece.
  • the number of components of the hearing instrument as well as the number of assembly steps is kept low.
  • a seamless and thus particularly soundproof Connection between receiver and sound tube created.
  • a further advantageous embodiment is that at least one of the components plug and mounting insert consists at least partially of flexible material.
  • Flexible material allows a stable mechanical hold while reversible insertability and solvability of the connector.
  • flexible material provides good conditions for a sound-proof and otherwise also for moisture and contamination tight connection.
  • flexible material is also well suited for vibration decoupling of receiver and housing.
  • a further advantageous embodiment is that the plug connection between the socket and the plug when plugged into the socket plug forms a seal for sound in audible for the human ear frequency range, in particular in the frequency range of 20Hz to 20kHz. This frequency range is of particular interest, since the output signals of the receiver are just in this frequency range.
  • a further advantageous embodiment is that the mounting insert is designed such that it attenuates from the receiver to the housing and vice versa transmitted vibrations.
  • another function is integrated into the mounting insert.
  • the higher integration has an advantageous effect on the number of components of the hearing instrument and thus on installation effort, maintenance, logistical effort and the size of the hearing instrument.
  • a further advantageous embodiment is that the receiver compartment is designed such that the receiver is held by the receiver compartment, and that the receiver in the receiver compartment is reversibly used and removable.
  • a further advantageous embodiment is that the mounting insert has a collar, that the housing has a socket corresponding to the collar, and that the mounting insert is held in the housing by the collar inserted into the socket.
  • a further advantageous embodiment is that the collar is arranged in the region of the socket.
  • the region of the mounting insert, in which the receiver compartment and thus the receiver is arranged is not directly in contact with the holder in the housing. Instead, the area of the receiver compartment can be arranged without direct contact with the housing. This helps to prevent the transmission of vibrations between the housing and the receiver.
  • a further advantageous embodiment is that the plug is made in one piece with the sound tube by a multi-component injection molding process or by an overmolding process.
  • a multi-component injection molding process is understood to be a conventional process in which the sound tube and plug components are either made to merge into one another or are produced one after the other, with the second-fabricated component being sprayed onto the first fabricated component.
  • Umspritz method also referred to as Insert Mold Vefahren
  • a conventional injection molding process is understood, in which initially one of the components sound tube and plug is made, and then sprayed the second component on the first made becomes.
  • Both multi-component injection molding and overmoulding allow efficient production of complex one-piece parts. This avoids an additional, separate plug and reduces the number of components of the hearing instrument. The reduced number of components has an advantageous effect on the installation effort, the maintenance effort, the logistical effort and also on the size of the plug-type sound tube arrangement.
  • a further advantageous embodiment is that the plug and the socket each have at least two circumferential recesses or elevations. This causes a higher mechanical stability of the plug connection between plug and socket and a better tightness.
  • FIG. 1 is a plug connection between a sound tube 3 and a housing 1 of a hearing instrument shown schematically as a sectional view.
  • the housing 1 is shown only as a housing cutout.
  • the connector is formed by a plug 8 and a socket 6 according to the invention.
  • an ear piece 10 which is designed as a so-called. Dome.
  • the housing 1 of the hearing instrument facing the end of the sound tube 3 is the plug 8. He is plugged into the socket 6 of the housing 1.
  • the plug 8 is molded on the sound tube 3 in one piece or manufactured in one piece by injection molding with this.
  • the sound tube 3 consists of a conventionally customary material, as well as the plug 8.
  • 8 different materials can be used for the sound tube 3 and the plug, for example, in a multi-component injection molding process can be processed.
  • the plug 8 has a rotationally symmetrical cross-section along its longitudinal axis. He has at its housing-side end and in the vicinity of each a circumferential elevation 9, which serves to lock the plug 8 mechanically stable in the socket 6 can.
  • the similar circumferential sealing lips configured elevations 9 have a flexibility that allow insertion and withdrawal of the plug 8 by hand, while ensuring sufficient stability of the connector against accidental withdrawal.
  • a mounting insert 4 is inserted, whose output-side section forms the socket 6.
  • the bushing 6, which has a rotationally symmetrical opening along its longitudinal axis circumferential recesses 7 are formed within the opening.
  • the recesses 7 are shaped so that they receive the circumferential elevations 9 of the plug 8.
  • the plug 8 engages in the socket 6 and is secured by the mutual engagement of recesses 7 and elevations 9 against unintentional release.
  • the recesses 7 and elevations 9 and the remaining plug 8 and the remaining socket 6 are so against each other that the connector against ingress of moisture and impurities and against the passage of sound, especially in the perceptible to human hearing frequency range from about 20 Hz to 20 kHz, sealed.
  • the tightness is adjusted by the surface finish of the plug 8 and the socket 6 and by their flexibility or elasticity.
  • a receiver compartment 5 is formed in the mounting insert 4.
  • a receiver 2 is inserted in the receiver compartment 5.
  • the receiver compartment 5 has an opening 11.
  • the material of the mounting insert 4, at least in the area of the receiver compartment 5, is such that the forwarding of vibrations from the receiver 2 to the housing 1 and vice versa is prevented or at least reduced. This decoupling of the receiver 2 from the housing 1 with respect to vibration is among other things important to improve the acoustic properties of the hearing instrument and in particular to reduce the tendency to feedback due to transmitted via the housing 1 structure-borne sound.
  • the seamless one-piece design of the mounting insert 4 allows an unobtrusive and particularly tight connection of the sound tube 3 to the output of the receiver. 2
  • FIG. 2 is the mounting insert 4 in the housing 1 with infected sound tube 3 shown schematically as a sectional view.
  • the housing 1 is as shown above only as a section.

  • the collar 13 is inserted into a correspondingly shaped socket 12 of the housing 1. Due to the mutual engagement of collar 13 and socket 12 of the mounting insert 4 is held in the housing 1.
  • the collar 13 is located in the region of that portion of the mounting insert 4, in which the sleeve 6 is formed.
  • the opposite portion in which the receiver compartment 5 is formed is not in direct contact with the housing 1. Rather, the section with the receiver compartment 5 is arranged floating in the housing 1, and is held exclusively by the collar 13 in the socket-side portion of the mounting insert 4. In this way, structure-borne sound bridges between the receiver and the housing 1 are minimized, which supports the decoupling of the housing 1 and receiver with respect to vibration.
  • FIG. 3 is the mounting insert 4 in the housing 1 without plug and sound tube shown schematically as a sectional view.
  • the receiver 2 is inserted through the opening 11 provided for this purpose.
