Definitions
- the invention relates to a hearing aid, in particular to a hearing aid.
- a hearing aid in particular a hearing aid usually serves a person with limited hearing to compensate for at least a portion of their hearing impairment.
- the hearing device usually comprises at least one microphone, by means of which sounds (acoustic sound signals) from the surroundings of the hearing device (and thus also from the surroundings of the hearing device wearer) are detected and converted into an electrical signal.
- this electrical signal is conventionally amplified - optionally after filtering interference signals - and output via a loudspeaker (also often referred to as a "receiver") to the ear of the hearing device wearer.
- the signals can also be transmitted via a cochlear implant, a bone conduction implant or the like to the hearing center of the hearing device wearer.
- the hearing aid is usually worn on the body, in particular in or on the ear whose hearing is limited.
- the hearing aid is frequently subjected to the action of dirt (for example dust) and / or of liquids (body perspiration, rainwater or even earwax).
- dirt for example dust
- liquids body perspiration, rainwater or even earwax
- the hearing aid regularly comprises a housing which encloses these electronic components.
- this housing regularly has a microphone opening assigned to the microphone of the hearing device, through which the acoustic sound signals (sound waves) can hit the microphone as unhindered as possible.
- the microphone opening is often closed by means of a barrier impermeable to water as possible. This barrier is usually designed so thin that the impacting sound waves are attenuated as low as possible. The thickness of such barriers is approximately up to 50 microns.
- Soiling of the barrier for example by earwax, is known to result in reduced sound transmission, so that the barrier must be replaced, possibly also due to damage to the barrier. Therefore, such a barrier is partially interchangeable inserted into the housing. However, the barrier must also be sealed against the housing. Alternatively, however, such a barrier is also produced integrally with the housing or adhesively sealed (insoluble) with this.
- the invention has for its object to provide an improved protection of a microphone of a hearing aid from contamination.
- the hearing aid according to the invention comprises a first microphone which is suitable for detecting an acoustic (sound) signal from the surroundings of the hearing device and preferably for converting the acoustic signal into an electrical signal.
- the hearing aid comprises a housing in which the first microphone is arranged.
- the housing has a first microphone opening, through which the first microphone for detecting the acoustic signal is in (preferably acoustic) connection with the surroundings of the hearing device.
- the hearing aid comprises a first damping element, by means of which the first microphone is supported against the housing (preferably elastically). The first damping element is used in particular to reduce vibrations of the first microphone and to reduce a coupling of (transmitted via the housing) structure-borne noise in the first microphone.
- the hearing aid comprises a first (preferably watertight) barrier element for sound-permeable sealing of the first microphone opening. That is, the first barrier element for protecting the first microphone as well as the interior of the housing against impurities that can enter through the first microphone opening, especially against moisture, is used.
- the first damping element in this case has a pocket in which the first barrier element is reversibly (ie interchangeable) added.
- the first barrier element in the intended final assembly state of the hearing device) is sealed circumferentially around the first microphone opening against the housing by means of the first damping element. It is preferable for a rim of the first damping element surrounding the pocket of the first damping element to be sealingly surrounding the housing around the first microphone opening.
- the first damping element thus forms, on the one hand, a vibration damping for the first microphone and advantageously additionally a holder and a seal for the first barrier element with respect to the housing.
- the first barrier element can be exchanged as a single part easily and inexpensively.
- installation effort for sealing (eg by gluing) of the first barrier element relative to the housing can also be saved.
- the first damping element is also arranged interchangeably in the housing, so that in In this case, the first barrier element can be exchanged in a simple manner together with the first damping element.
- the housing of the hearing aid is formed like a shell and composed of at least two shell parts. This allows a simple mounting of the first microphone, the first damping element and the first barrier element in the housing.
- the first microphone opening is preferably formed in the shell part closest to the first microphone.
- the first damping element made of an elastic material, in particular of an elastic plastic, such as a (preferably thermoplastic) elastomer or a silicone, in particular a liquid silicone rubber (also referred to as liquid silicone rubber, short LSR).
- an elastic plastic such as a (preferably thermoplastic) elastomer or a silicone, in particular a liquid silicone rubber (also referred to as liquid silicone rubber, short LSR).
- the first damping element is injection molded from such a plastic. This allows easy manufacture of the damping element while maintaining high design freedom (i.e., complex structures can be easily formed).
- the first damping element has a breakthrough corresponding to the first microphone opening, through which the acoustic signal can strike the first microphone.
- the pocket for receiving the first barrier element is preferably formed as an undercut of this opening. Under “undercut” is understood here and below that the breakthrough (seen along its longitudinal axis) initially widened within the wall thickness of the damping element and then rejuvenated.
- at one of the two (distal) ends of the opening there is in front of the longitudinal axis of the opening, in particular a ring-shaped closed and in comparison to the length of the opening thin-walled edge.
- a second such edge is also arranged at the opposite end.
- the undercut is in this case arranged between these edges and bounded on both sides by these edges.
- the undercut is shaped in particular in such a way in that the first barrier element arranged in the undercut is positively held preferably by the two edges, but at least by an edge.
- the aperture in the first damping element and the first barrier element are each approximately circular (i.e., exactly circular or slightly oval).
- the inner dimensions of the aperture and the outer dimensions of the first barrier element are therefore hereinafter generally referred to as “inner diameter” or “outer diameter” for simplicity.
- inner diameter or “outer diameter” for simplicity.
- oval aperture and oval first barrier element these designations stand for their smallest inner dimensions or smallest outer dimensions .
- the aperture at one of its distal ends (with respect to the other end) is increased.
- the thin-walled edge of the first damping element arranged at this enlarged end does not protrude so far in the direction of the longitudinal axis of the opening as the region of the opening arranged on the other side of the undercut, in particular the "second" thin-walled edge optionally present there.
- the enlarged area of the opening, in particular the edge arranged there is dimensioned such that the first barrier element inserted into the undercut is only slightly covered (in comparison to the outer diameter of the first barrier element) by this area or edge.
- the first damping element is made of elastic plastic. In this case, namely, the first barrier element can be easily inserted over this edge of the aperture by utilizing its elastic deformation capacity in the pocket or undercut, the edge "snaps" onto the first barrier element.
- the undercut is opened in a direction transverse to the longitudinal axis of the opening in such a way that an insertion slot for the first barrier element is formed. That is to say, the first damping element has a window (the insertion slot) arranged perpendicular to its thickness direction, which is formed from the side of the first damping element into the opening.
- the first barrier element can be inserted from the side (that is to say perpendicular to the longitudinal axis of the opening) through the insertion shaft into the undercut - without or with only negligible deformation of the damping element.
- the regions of the opening which delimit the undercut, in particular the respective edges, are comparatively stiff and are designed further in the opening (with a larger width). Ie. they cover the first barrier element (in comparison to the embodiment described above) over a larger area and thereby keep it particularly stable and tight in the undercut.
- the pocket or the undercut of the first damping element is dimensioned such that the (inserted into the pocket) first barrier element is braced against the first damping element.
- the inner diameter of the undercut is made slightly smaller than the outer diameter of the barrier element.
- the barrier element in addition to the form-fit in the manner of an interference fit is also held non-positively in the first damping element. In addition, this also increases the sealing effect between the damping element and the barrier element.
- the distance between the two edges bounding the undercut is made smaller than the thickness of the barrier element.
- the first barrier element comprises a particularly hydrophobic membrane.
- This membrane is expediently sound-permeable.
- the membrane is formed by a fine-pored (for example, mesh or fleece-like) material. This material is preferably hydrophobic or at least hydrophobic in itself.
- the membrane is additional or alternatively formed impermeable to water, for example in the form of a polyetherester film or a microporous polytetrafluoroethylene (short: PTFE) film having a material thickness of about 5 to 50 microns.
- this membrane is mounted in a circumferential frame, which has a higher rigidity compared to the membrane. This allows dimensional stability of the membrane and thus easy handling of the barrier element per se-without the risk of the membrane collapsing.
- the frame is molded in particular circumferentially to the membrane.
- the hearing device comprises a second microphone, so that a directivity can be achieved by means of a suitable interconnection of the two microphones.
- the hearing device in particular comprises in each case a second damping element and second barrier element assigned to the second microphone.
- the second damping element and the second barrier element are preferably designed to be similar to the above-described first damping element and the first barrier element.
- the first and the second damping element also integrally connected to each other -. Via an integral (i.e., monolithic) connecting web formed with the first and second damping members.
- the first and second damping elements are manufactured together in an injection molding process or a vulcanization process (including the connecting land).
- the handling of the first and the second damping element is advantageously increased, since only one component - namely the first and the second damping element comprehensive "damper" is present. It is also possible to replace this damper part together with the two barrier elements, which in turn is advantageous in terms of the handling of the comparatively small barrier elements.
- the hearing device comprises an antenna for electromagnetic (in particular radio-technical) communication with a separate device.
- a separate device is for example an external audio signal source (for example a smartphone, a TV set or the like) or a second hearing device which is set up and provided for the binaural supply of both ears of the hearing device wearer.
- the antenna is integrated in particular in the first and / or the second damping element, but preferably in the damper part formed from the first and the second damping element.
- the antenna is injected as a metallic insert part in this damper part, in particular in the connecting web (ie encapsulated with the plastic of the first and second damping element). Characterized a functional integration of several separate components of the hearing aid is achieved in a component and thus simplifies the handling of the components during assembly.
- the hearing device comprises a circuit carrier, which carries in particular a signal processing unit for evaluating and amplifying the detected acoustic signals and tracks for electrical contacting of the first microphone and optionally the second microphone and the antenna with the signal processing unit.
- the antenna is in this case preferably connected by means of a solder connection with an associated conductor track of the circuit carrier.
- the antenna is contacted by means of a plug connection, a clamp connection, a spring contact o. The like. With the corresponding conductor track.
- FIG. 1 is a hearing aid, briefly referred to as hearing aid 1, shown.
- the hearing aid 1 is designed as a so-called behind-the-ear hearing aid (short: BTE hearing aid) and is thus worn by a hearing aid wearer behind its outer ear.
- the hearing aid 1 comprises a first microphone 2 and a second microphone 3, which are each set up and provided to detect an acoustic signal (short: sound signal) from the surroundings 4 of the hearing device 1. Furthermore, the first and the second microphone 2 and 3 are adapted to convert the detected sound signal into an electrical signal and pass it on to a signal processing unit 6 of the hearing aid 1.
- the respective electrical signal is evaluated, filtered and then amplified to a loudspeaker 8 (also referred to as a "handset") of the hearing aid 1.
- the loudspeaker 8 By means of the loudspeaker 8, the amplified signal is converted into a corresponding acoustic (output) signal and output to the ear of the hearing aid wearer.
- the two microphones 2 and 3, the signal processing unit 6 and the loudspeaker 8 each form an electronic component of the hearing device 1 and are arranged in a housing 10 of the hearing aid 1 for rough protection against environmental influences (impurities).
- the housing 10 is designed shell-like and comprises for mounting the two microphones 2 and 3 and the other electronic components a detachable shell part, which is hereinafter referred to as lid 12 (indicated by the dashed line in FIG FIG. 1 ).
- the two damping elements 14 and 16 are injection molded from an elastic plastic, concretely made of a silicone (LSR).
- the two microphones 2 and 3 are arranged below the lid 12, that is covered by this.
- a first microphone opening 18 and a second microphone opening 20 are formed in the cover 12, which are respectively assigned to the first and the second microphone 2 and 3.
- the hearing aid 1 further includes two (the respective microphone 2 and 3 respectively assigned) barrier elements 22 and 24th These barrier elements 22 and 24 are each reversibly (ie interchangeably) held in the respective damping element 14 or 16. The sealing of the respective barrier element 20 or 24 relative to the housing 10, specifically the cover 12, takes place via the respective damping element 14 and 16.
- the barrier element 22 and 24 comprises a hydrophobic, but sound-permeable membrane 26, which is clamped and held by an annular closed, injection-molded to the membrane 26 frame 28 frame.
- the respective barrier element 22 and 24 is configured with a circular outer contour (cf. FIG. 4 ).
- the damping element 14 and 16 surrounds the respective microphone 2 and 3 on the front side and braces this elastic
- the damping element 14 or 16 is hollow cylindrical and thus has a corresponding with the respective microphone opening 18 and 20, circular aperture 30 through which sound signals to the microphone 2 and 3 respectively can reach.
- the opening 30 is formed with an undercut 32, ie a partial enlargement of the inner diameter of the opening 30.
- the undercut 32 forms a pocket for receiving the frame 28 of the barrier element 22 or 24.
- the barrier element 22 or 24 is positively in the undercut 32 of a (compared to the length of the opening 30) thin-walled edge 34 of the damping element 22 and 24 respectively held in the breakthrough 30 inside. This edge 34 is further in the intended final assembly state of the hearing aid 1 according to FIG. 2 on the inside of the lid 12 circumferentially around the respective microphone opening 18 and 20, so that a passage of moisture between the lid 12 and the barrier element 22 and 24 is prevented.
- the edge 34 of the damping element 14 or 16 is designed such that it protrudes only slightly beyond the frame 28 with respect to the outer diameter of the (circular) barrier element 22 or 24.
- the barrier element 22 or 24 can be inserted into the undercut 32 (i.e., with slight elastic deformation thereof) by overcoming the elastic restoring force of the edge 34, whereby the edge 34 "snaps" over the frame 28.
- FIG. 3 an alternative embodiment of the damping elements 14 and 16 is shown.
- the damping elements 14 and 16 are compared to the embodiment according to FIG. 2 run flat and are only front side on the respective microphone 2 and 3 (see. FIG. 3 ).
- the two damping elements 14 and 16 are monolithically connected to each other via a connecting web 36. This results in improved handling of both damping elements 14 and 16.
- the undercut 32 of the two damping elements 14 and 16 is arranged approximately centrally with respect to the length of the opening 30 in the respective damping element 14 and 16 respectively.
- the undercut 32 is thus delimited by the edge 34 in the direction of the microphone opening 18 or 20 (hereinafter referred to as the front side of the respective sealing element 14 or 16). On the rear side, the undercut 32 is delimited by a further edge 38 which terminates the opening 30 and the damping element 14 or 16.
- the edge 38 has the same as the edge 34 in comparison to the length of the opening 30 small wall thickness.
- the back edge 38 analogous to the edge 34 of the embodiment according to FIG. 2 with a comparatively large inner diameter (ie with a small width).
- the inner diameter of the edge 38 is slightly smaller than the outer diameter of the damping element 22 or 24, so that the respective damping element 22 and 24 are used in this embodiment from the back in the undercut 32 (with deformation of the edge 38) can.

Description
Die Erfindung bezieht sich auf ein Hörgerät, insbesondere auf ein Hörhilfegerät.The invention relates to a hearing aid, in particular to a hearing aid.
Ein Hörgerät, insbesondere ein Hörhilfegerät dient üblicherweise einer Person mit eingeschränktem Hörvermögen dazu, zumindest einen Teil ihrer Höreinschränkung auszugleichen. Dazu umfasst das Hörgerät meist wenigstens ein Mikrophon, mittels dessen Geräusche (akustische Schallsignale) aus der Umgebung des Hörgeräts (und somit auch aus der Umgebung des Hörgeräteträgers) erfasst und in ein elektrisches Signal gewandelt werden. In einer Signalverarbeitungseinheit des Hörgeräts wird dieses elektrische Signal herkömmlicherweise - gegebenenfalls nach einer Filterung von Störsignalen - verstärkt und über einen Lautsprecher (auch oft als "Hörer" bezeichnet) an das Ohr des Hörgeräteträgers ausgegeben. Alternativ können die Signale auch über ein Cochlea-Implantat, ein Knochenleitungs-Implantat oder dergleichen an das Hörzentrum des Hörgeräteträgers übertragen werden.A hearing aid, in particular a hearing aid usually serves a person with limited hearing to compensate for at least a portion of their hearing impairment. For this purpose, the hearing device usually comprises at least one microphone, by means of which sounds (acoustic sound signals) from the surroundings of the hearing device (and thus also from the surroundings of the hearing device wearer) are detected and converted into an electrical signal. In a signal processing unit of the hearing device, this electrical signal is conventionally amplified - optionally after filtering interference signals - and output via a loudspeaker (also often referred to as a "receiver") to the ear of the hearing device wearer. Alternatively, the signals can also be transmitted via a cochlear implant, a bone conduction implant or the like to the hearing center of the hearing device wearer.
Das Hörgerät wird üblicherweise am Körper, insbesondere in oder an dem Ohr, dessen Hörvermögen eingeschränkt ist, getragen. Am Körper, insbesondere am Kopf des Hörgeräteträgers, ist das Hörgerät jedoch häufig der Einwirkung von Schmutz (beispielsweise Staub) und/oder von Flüssigkeiten (Körperschweiß, Regenwasser oder auch Ohrenschmalz) unterworfen. Je nach Grad der Einschränkung des Hörvermögens und/oder der Nutzungswünsche des jeweiligen Hörgeräteträgers kann es auch vorkommen, dass das Hörgerät direkt mit Wasser, z.B. unter der Dusche oder im Schwimmbad, in Kontakt kommt.The hearing aid is usually worn on the body, in particular in or on the ear whose hearing is limited. On the body, in particular on the head of the hearing aid wearer, however, the hearing aid is frequently subjected to the action of dirt (for example dust) and / or of liquids (body perspiration, rainwater or even earwax). Depending on the degree of restriction of the hearing and / or the user's wishes of the respective hearing aid wearer, it may also happen that the hearing aid comes into direct contact with water, eg under the shower or in the swimming pool.
Das Mikrophon des Hörgeräts sowie dessen Signalverarbeitungseinheit stellen allerdings elektronische Bauelemente dar, die durch unmittelbaren Kontakt mit Feuchtigkeit in ihrer Funktion beeinträchtigt oder gar zerstört werden können. Zum groben Schutz dieser elektronischen Bauelemente umfasst das Hörgerät regelmäßig ein Gehäuse, das diese elektronischen Bauelemente umhüllt. Um jedoch die akustischen Schallsignale aus der Umgebung möglichst präzise erfassen zu können, weist dieses Gehäuse regelmäßig eine dem Mikrophon des Hörgeräts zugeordnete Mikrophonöffnung auf, durch die hindurch die akustischen Schallsignale (Schallwellen) möglichst ungehindert auf das Mikrophon treffen können. Um dennoch das Mikrophon vor eindringender Feuchtigkeit oder sonstigen Verunreinigungen schützen zu können, wird die Mikrophonöffnung häufig mittels einer möglichst wasserundurchlässigen Barriere verschlossen. Diese Barriere ist meist derart dünn gestaltet, dass die auftreffenden Schallwellen möglichst gering abgeschwächt werden. Die Dicke solcher Barrieren beträgt dabei etwa bis zu 50 µm.The microphone of the hearing aid and its signal processing unit, however, represent electronic components that can be impaired by their direct contact with moisture in their function or even destroyed. For the rough protection of these electronic components, the hearing aid regularly comprises a housing which encloses these electronic components. However, in order to be able to record the acoustic sound signals from the environment as precisely as possible, this housing regularly has a microphone opening assigned to the microphone of the hearing device, through which the acoustic sound signals (sound waves) can hit the microphone as unhindered as possible. Nevertheless, in order to protect the microphone from penetrating moisture or other contaminants, the microphone opening is often closed by means of a barrier impermeable to water as possible. This barrier is usually designed so thin that the impacting sound waves are attenuated as low as possible. The thickness of such barriers is approximately up to 50 microns.
Eine Verschmutzung der Barriere beispielsweise durch Ohrenschmalz führt erkanntermaßen zu einer verminderten Schalldurchlässigkeit, so dass die Barriere ausgetauscht werden muss-gegebenenfalls auch aufgrund einer Beschädigung der Barriere. Deshalb wird eine solche Barriere teilweise austauschbar in das Gehäuse eingesetzt. Dabei muss die Barriere aber zusätzlich gegen das Gehäuse abgedichtet werden. Alternativ wird eine solche Barriere aber auch integral mit dem Gehäuse gefertigt oder (unlösbar) dicht schließend mit diesem verklebt.Soiling of the barrier, for example by earwax, is known to result in reduced sound transmission, so that the barrier must be replaced, possibly also due to damage to the barrier. Therefore, such a barrier is partially interchangeable inserted into the housing. However, the barrier must also be sealed against the housing. Alternatively, however, such a barrier is also produced integrally with the housing or adhesively sealed (insoluble) with this.
Der Erfindung liegt die Aufgabe zugrunde, einen verbesserten Schutz eines Mikrophons eines Hörgeräts vor Verunreinigung anzugeben.The invention has for its object to provide an improved protection of a microphone of a hearing aid from contamination.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Hörgerät mit den Merkmalen des Anspruchs 1. Vorteilhafte und teils für sich erfinderische Ausführungsformen und Weiterbildungen der Erfindung sind in den Unteransprüchen und der nachfolgenden Beschreibung dargelegt.This object is achieved by a hearing aid with the features of
Das erfindungsgemäße Hörgerät umfasst ein erstes Mikrophon, das zur Erfassung eines akustischen (Schall-)Signals aus der Umgebung des Hörgeräts sowie vorzugsweise zur Wandlung des akustischen Signals in ein elektrisches Signal dient. Des Weiteren umfasst das Hörgerät ein Gehäuse, in dem das erste Mikrophon angeordnet ist. Das Gehäuse weist dabei eine erste Mikrophonöffnung auf, durch die hindurch das erste Mikrophon zur Detektion des akustischen Signals mit der Umgebung des Hörgeräts in (vorzugsweise akustischer) Verbindung steht. Des Weiteren umfasst das Hörgerät ein erstes Dämpfungselement, mittels dessen das erste Mikrophon gegen das Gehäuse (vorzugsweise elastisch) abgestützt ist. Das erste Dämpfungselement dient insbesondere zur Verringerung von Vibrationen des ersten Mikrophons und zur Verringerung einer Einkopplung von (über das Gehäuse übertragenem) Körperschall in das erste Mikrophon. Außerdem umfasst das Hörgerät ein erstes (vorzugsweise wasserdichtes) Barriereelement zur schalldurchlässigen Abdichtung der ersten Mikrophonöffnung. Das heißt, dass das erste Barriereelement zum Schutz des ersten Mikrophons sowie des Innenraums des Gehäuses gegen Verunreinigungen, die durch die erste Mikrophonöffnung eintreten können, insbesondere gegen Feuchtigkeit, dient. Das erste Dämpfungselement weist hierbei eine Tasche auf, in der das erste Barriereelement reversibel (d. h. austauschbar) aufgenommen ist. Des Weiteren ist das erste Barriereelement (im bestimmungsgemäßen Endmontagezustand des Hörgeräts) mittels des ersten Dämpfungselements umlaufend um die erste Mikrophonöffnung gegen das Gehäuse abgedichtet. Vorzugswiese liegt dazu ein die Tasche des ersten Dämpfungselements umlaufend begrenzender Rand des ersten Dämpfungselements um die erste Mikrophonöffnung herum am Gehäuse dichtend an.The hearing aid according to the invention comprises a first microphone which is suitable for detecting an acoustic (sound) signal from the surroundings of the hearing device and preferably for converting the acoustic signal into an electrical signal. Furthermore, the hearing aid comprises a housing in which the first microphone is arranged. In this case, the housing has a first microphone opening, through which the first microphone for detecting the acoustic signal is in (preferably acoustic) connection with the surroundings of the hearing device. Furthermore, the hearing aid comprises a first damping element, by means of which the first microphone is supported against the housing (preferably elastically). The first damping element is used in particular to reduce vibrations of the first microphone and to reduce a coupling of (transmitted via the housing) structure-borne noise in the first microphone. In addition, the hearing aid comprises a first (preferably watertight) barrier element for sound-permeable sealing of the first microphone opening. That is, the first barrier element for protecting the first microphone as well as the interior of the housing against impurities that can enter through the first microphone opening, especially against moisture, is used. The first damping element in this case has a pocket in which the first barrier element is reversibly (ie interchangeable) added. Furthermore, the first barrier element (in the intended final assembly state of the hearing device) is sealed circumferentially around the first microphone opening against the housing by means of the first damping element. It is preferable for a rim of the first damping element surrounding the pocket of the first damping element to be sealingly surrounding the housing around the first microphone opening.
Das erste Dämpfungselement bildet somit einerseits eine Vibrationsdämpfung für das erste Mikrophon sowie vorteilhafterweise zusätzlich eine Halterung und eine Dichtung für das erste Barriereelement gegenüber dem Gehäuse. Insbesondere dadurch, dass das erste Barriereelement reversibel in der Tasche des ersten Dämpfungselements aufgenommen ist, kann das erste Barriereelement als Einzelteil einfach und kostengünstig ausgetauscht werden. Des Weiteren kann auch Montageaufwand zur Abdichtung (z.B. durch Kleben) des ersten Barriereelements gegenüber dem Gehäuse eingespart werden. Vorzugsweise ist das erste Dämpfungselement ebenfalls austauschbar in dem Gehäuse angeordnet, so dass in diesem Fall auch das erste Barriereelement gemeinsam mit dem ersten Dämpfungselement auf einfache Weise ausgewechselt werden kann.The first damping element thus forms, on the one hand, a vibration damping for the first microphone and advantageously additionally a holder and a seal for the first barrier element with respect to the housing. In particular, the fact that the first barrier element is reversibly accommodated in the pocket of the first damping element, the first barrier element can be exchanged as a single part easily and inexpensively. Furthermore, installation effort for sealing (eg by gluing) of the first barrier element relative to the housing can also be saved. Preferably, the first damping element is also arranged interchangeably in the housing, so that in In this case, the first barrier element can be exchanged in a simple manner together with the first damping element.
Vorzugsweise ist das Gehäuse des Hörgeräts schalenartig ausgebildet und aus wenigstens zwei Schalenteilen zusammengesetzt. Dadurch wird eine einfache Montage des ersten Mikrophons, des ersten Dämpfungselements sowie des ersten Barriereelements in dem Gehäuse ermöglicht. In diesem Fall ist die erste Mikrophonöffnung vorzugsweise in dem dem ersten Mikrophon nächstliegenden Schalenteil ausgeformt.Preferably, the housing of the hearing aid is formed like a shell and composed of at least two shell parts. This allows a simple mounting of the first microphone, the first damping element and the first barrier element in the housing. In this case, the first microphone opening is preferably formed in the shell part closest to the first microphone.
In einer bevorzugten Ausführung ist das erste Dämpfungselement aus einem elastischen Material, insbesondere aus einem elastischen Kunststoff, wie beispielsweise einem (vorzugsweise thermoplastischen) Elastomer oder einem Silikon, insbesondere einem Flüssigsilikonkautschuk (auch englisch als liquid silicone rubber, kurz: LSR bezeichnet) gefertigt. Vorzugsweise ist das erste Dämpfungselement aus einem solchen Kunststoff spritzgegossen. Dadurch wird eine einfache Fertigung des Dämpfungselements bei zugleich hoher Designfreiheit (d.h. es können auf einfache Weise komplexe Strukturen ausgeformt werden) ermöglicht.In a preferred embodiment, the first damping element made of an elastic material, in particular of an elastic plastic, such as a (preferably thermoplastic) elastomer or a silicone, in particular a liquid silicone rubber (also referred to as liquid silicone rubber, short LSR). Preferably, the first damping element is injection molded from such a plastic. This allows easy manufacture of the damping element while maintaining high design freedom (i.e., complex structures can be easily formed).
In einer zweckmäßigen Ausführung weist das erste Dämpfungselement einen zu der ersten Mikrophonöffnung korrespondierenden Durchbruch auf, durch den hindurch das akustische Signal auf das erste Mikrophon treffen kann. Die Tasche zur Aufnahme des ersten Barriereelements ist dabei vorzugsweise als Hinterschnitt dieses Durchbruchs ausgebildet. Unter "Hinterschnitt" wird hier und im Folgenden verstanden, dass sich der Durchbruch (entlang seiner Längsachse gesehen) innerhalb der Wandstärke des Dämpfungselements zunächst verbreitert und anschließend wieder verjüngt. In einer vorteilhaften Ausgestaltung steht dabei an einem der beiden (distalen) Enden des Durchbruchs ein insbesondere ringförmig geschlossener und im Vergleich zur Länge des Durchbruchs dünnwandiger Rand in Richtung auf die Längsachse des Durchbruchs vor. Vorzugsweise ist auch an dem gegenüberliegenden Ende ein zweiter solcher Rand angeordnet. Der Hinterschnitt ist in diesem Fall zwischen diesen Rändern angeordnet und beidseitig von diesen begrenzt. Der Hinterschnitt ist insbesondere derart ausgeformt, dass das in dem Hinterschnitt angeordnete erste Barriereelement formschlüssigvorzugsweise von den beiden Rändern, zumindest aber von einem Rand-gehaltert ist. Zur Abdichtung des ersten Barriereelements gegen das Gehäuse (bzw. gegen den einen Schalenteil des Gehäuses) liegt das erste Dämpfungselement mit dem den Hinterschnitt zur Vorderseite des ersten Dämpfungselements-d. h. in Richtung auf die erste Mikrophonöffnung-begrenzenden Rand umlaufend an dem Gehäuse an.In an expedient embodiment, the first damping element has a breakthrough corresponding to the first microphone opening, through which the acoustic signal can strike the first microphone. The pocket for receiving the first barrier element is preferably formed as an undercut of this opening. Under "undercut" is understood here and below that the breakthrough (seen along its longitudinal axis) initially widened within the wall thickness of the damping element and then rejuvenated. In an advantageous embodiment, at one of the two (distal) ends of the opening there is in front of the longitudinal axis of the opening, in particular a ring-shaped closed and in comparison to the length of the opening thin-walled edge. Preferably, a second such edge is also arranged at the opposite end. The undercut is in this case arranged between these edges and bounded on both sides by these edges. The undercut is shaped in particular in such a way in that the first barrier element arranged in the undercut is positively held preferably by the two edges, but at least by an edge. For sealing the first barrier element against the housing (or against the one shell part of the housing), the first damping element with the undercut to the front of the first damping element-ie in the direction of the first microphone opening-limiting edge circumferentially on the housing.
Vorzugsweise sind der Durchbruch in dem ersten Dämpfungselement sowie das erste Barriereelement jeweils näherungsweise kreisförmig (d.h. exakt kreisrund oder geringfügig oval) ausgeformt. Die Innenabmessungen des Durchbruchs und die Außenabmessungen des ersten Barriereelements werden deshalb zur Vereinfachung im Folgenden allgemein mit "Innendurchmesser" bzw. "Außendurchmesser" bezeichnet, wobei diese Bezeichnungen im Fall eines ovalen Durchbruchs und ovalen ersten Barriereelements jeweils für deren kleinste Innenabmessung bzw. kleinste Außenabmessung stehen.Preferably, the aperture in the first damping element and the first barrier element are each approximately circular (i.e., exactly circular or slightly oval). The inner dimensions of the aperture and the outer dimensions of the first barrier element are therefore hereinafter generally referred to as "inner diameter" or "outer diameter" for simplicity. In the case of an oval aperture and oval first barrier element, these designations stand for their smallest inner dimensions or smallest outer dimensions ,
In einer weiteren zweckmäßigen Ausführung ist der Durchbruch an einem seiner distalen Enden (in Bezug auf das jeweils andere Ende) vergrößert. Vorzugsweise ragt der an diesem vergrößerten Ende angeordnete dünnwandige Rand des ersten Dämpfungselements nicht so weit in Richtung auf die Längsache des Durchbruchs vor wie der auf der anderen Seite des Hinterschnitts angeordnete Bereich des Durchbruchs, insbesondere der dort gegebenenfalls vorhandene "zweite" dünnwandige Rand. Der vergrößerte Bereich des Durchbruchs, insbesondere der dort angeordnete Rand ist dabei derart dimensioniert, dass das in den Hinterschnitt eingesetzte erste Barriereelement nur geringfügig (im Vergleich zum Außendurchmesser des ersten Barriereelements) von diesem Bereich bzw. Rand überdeckt ist. Dies ist insbesondere für den Fall vorteilhaft, dass das erste Dämpfungselement aus elastischem Kunststoff gefertigt ist. In diesem Fall kann nämlich das erste Barriereelement auf einfache Weise über diesen Rand des Durchbruchs unter Ausnutzung dessen elastischen Deformationsvermögens in die Tasche bzw. den Hinterschnitt eingesetzt werden, wobei der Rand auf das erste Barriereelement "aufschnappt".In a further expedient embodiment, the aperture at one of its distal ends (with respect to the other end) is increased. Preferably, the thin-walled edge of the first damping element arranged at this enlarged end does not protrude so far in the direction of the longitudinal axis of the opening as the region of the opening arranged on the other side of the undercut, in particular the "second" thin-walled edge optionally present there. The enlarged area of the opening, in particular the edge arranged there, is dimensioned such that the first barrier element inserted into the undercut is only slightly covered (in comparison to the outer diameter of the first barrier element) by this area or edge. This is particularly advantageous for the case that the first damping element is made of elastic plastic. In this case, namely, the first barrier element can be easily inserted over this edge of the aperture by utilizing its elastic deformation capacity in the pocket or undercut, the edge "snaps" onto the first barrier element.
In einer alternativen Ausführung ist der Hinterschnitt in einer quer zur Längsachse des Durchbruchs stehenden Richtung derart geöffnet, dass ein Einschubschacht für das erste Barriereelement gebildet ist. Das heißt, dass das erste Dämpfungselement ein senkrecht zu seiner Dickenrichtung angeordnetes Fenster (den Einschubschacht) aufweist, das von der Seite des ersten Dämpfungselements bis in den Durchbruch ausgeformt ist. Dadurch kann das erste Barriereelement von der Seite (d. h. senkrecht zur Längsachse des Durchbruchs) durch den Einschubschacht in den Hinterschnitt eingeschoben werden - ohne oder unter lediglich vernachlässigbarer Deformation des Dämpfungselements. Die den Hinterschnitt begrenzenden Bereiche des Durchbruchs, insbesondere die jeweiligen Ränder sind dabei vergleichsweise steif und weiter in den Durchbruch vorstehend ausgeführt (mit größerer Breite). D. h. sie überdecken das erste Barriereelement (im Vergleich zur vorstehend beschriebenen Ausführung) großflächiger und halten dieses dadurch besonders stabil und dicht in dem Hinterschnitt.In an alternative embodiment, the undercut is opened in a direction transverse to the longitudinal axis of the opening in such a way that an insertion slot for the first barrier element is formed. That is to say, the first damping element has a window (the insertion slot) arranged perpendicular to its thickness direction, which is formed from the side of the first damping element into the opening. As a result, the first barrier element can be inserted from the side (that is to say perpendicular to the longitudinal axis of the opening) through the insertion shaft into the undercut - without or with only negligible deformation of the damping element. The regions of the opening which delimit the undercut, in particular the respective edges, are comparatively stiff and are designed further in the opening (with a larger width). Ie. they cover the first barrier element (in comparison to the embodiment described above) over a larger area and thereby keep it particularly stable and tight in the undercut.
In einer weiteren zweckmäßigen Ausführung ist die Tasche bzw. der Hinterschnitt des ersten Dämpfungselements derart dimensioniert, dass das (in die Tasche eingesetzte) erste Barriereelement gegen das erste Dämpfungselement verspannt ist. Beispielsweise ist dabei der Innendurchmesser des Hinterschnitts geringfügig kleiner ausgeführt als der Außendurchmesser des Barriereelements. Dadurch ist das Barriereelement zusätzlich zu dem Formschluss nach Art einer Übermaßpassung auch kraftschlüssig in dem ersten Dämpfungselement gehaltert. Zudem wird dadurch auch die Dichtwirkung zwischen dem Dämpfungselement und dem Barriereelement erhöht. Alternativ oder zusätzlich ist der Abstand der beiden den Hinterschnitt begrenzenden Ränder kleiner ausgeführt als die Dicke des Barriereelements.In a further expedient embodiment, the pocket or the undercut of the first damping element is dimensioned such that the (inserted into the pocket) first barrier element is braced against the first damping element. For example, while the inner diameter of the undercut is made slightly smaller than the outer diameter of the barrier element. As a result, the barrier element in addition to the form-fit in the manner of an interference fit is also held non-positively in the first damping element. In addition, this also increases the sealing effect between the damping element and the barrier element. Alternatively or additionally, the distance between the two edges bounding the undercut is made smaller than the thickness of the barrier element.
In einer bevorzugten Ausführung umfasst das erste Barriereelement eine insbesondere hydrophobe Membran. Diese Membran ist zweckmäßigerweise schalldurchlässig. Insbesondere ist die Membran durch ein feinporiges (bspw. netz-oder vliesartiges) Material gebildet. Dieses Material ist dabei vorzugsweise an sich hydrophob oder zumindest hydrophob beschichtet. Optional ist die Membran zusätzlich oder alternativ wasserundurchlässig ausgebildet, beispielsweise in Form einer Polyetherester-Folie oder einer mikroporösen Polytetrafluorethylen- (kurz: PTFE-) Folie mit einer Materialstärke von jeweils etwa 5 bis 50 µm. Zweckmäßigerweise ist diese Membran in einem umlaufenden Rahmen aufgespannt, der im Vergleich zu der Membran eine höhere Steifigkeit aufweist. Dadurch wird eine dimensionale Stabilität der Membran und somit eine einfache Handhabung des Barriereelements an sich ermöglicht-ohne das Risiko, dass die Membran in sich zusammenzufällt. Der Rahmen ist insbesondere umlaufend an die Membran angespritzt.In a preferred embodiment, the first barrier element comprises a particularly hydrophobic membrane. This membrane is expediently sound-permeable. In particular, the membrane is formed by a fine-pored (for example, mesh or fleece-like) material. This material is preferably hydrophobic or at least hydrophobic in itself. Optionally, the membrane is additional or alternatively formed impermeable to water, for example in the form of a polyetherester film or a microporous polytetrafluoroethylene (short: PTFE) film having a material thickness of about 5 to 50 microns. Conveniently, this membrane is mounted in a circumferential frame, which has a higher rigidity compared to the membrane. This allows dimensional stability of the membrane and thus easy handling of the barrier element per se-without the risk of the membrane collapsing. The frame is molded in particular circumferentially to the membrane.
In einer weiteren bevorzugten Ausführung umfasst das Hörgerät ein zweites Mikrophon, so dass mittels einer geeigneten Verschaltung beider Mikrophone eine Richtwirkung erzielt werden kann. Des Weiteren umfasst das Hörgerät insbesondere jeweils ein dem zweiten Mikrophon zugeordnetes zweites Dämpfungselement und zweites Barriereelement. Das zweite Dämpfungselement und das zweite Barriereelement sind dabei vorzugsweise gleichartig zu dem vorstehend beschriebenen ersten Dämpfungselement und dem ersten Barriereelement ausgeführt. Zweckmäßigerweise sind in dieser Ausführung das erste und das zweite Dämpfungselement außerdem einstückig miteinander verbunden - z. B. über einen integral (d.h. monolithisch) mit dem ersten und dem zweiten Dämpfungselement ausgeformten Verbindungssteg. Insbesondere sind das erste und das zweite Dämpfungselement in einem Spritzgießverfahren oder einem Vulkanisierverfahren gemeinsam (einschließlich des Verbindungsstegs) gefertigt. Durch die einstückige Ausführung wird die Handhabbarkeit des ersten und des zweiten Dämpfungselements vorteilhafterweise erhöht, da lediglich ein Bauteil - nämlich das das erste und das zweite Dämpfungselement umfassende "Dämpferteil"-vorhanden ist. Dabei ist es auch möglich, dieses Dämpferteil gemeinsam mit den beiden Barriereelementen auszuwechseln, was wiederum hinsichtlich der Handhabbarkeit der vergleichsweise kleinen Barriereelemente vorteilhaft ist.In a further preferred embodiment, the hearing device comprises a second microphone, so that a directivity can be achieved by means of a suitable interconnection of the two microphones. In addition, the hearing device in particular comprises in each case a second damping element and second barrier element assigned to the second microphone. The second damping element and the second barrier element are preferably designed to be similar to the above-described first damping element and the first barrier element. Conveniently, in this embodiment, the first and the second damping element also integrally connected to each other -. Via an integral (i.e., monolithic) connecting web formed with the first and second damping members. In particular, the first and second damping elements are manufactured together in an injection molding process or a vulcanization process (including the connecting land). The one-piece design, the handling of the first and the second damping element is advantageously increased, since only one component - namely the first and the second damping element comprehensive "damper" is present. It is also possible to replace this damper part together with the two barrier elements, which in turn is advantageous in terms of the handling of the comparatively small barrier elements.
In einer weiteren zweckmäßigen Ausführung umfasst das Hörgerät eine Antenne zur elektromagnetischen (insbesondere funktechnischen) Kommunikation mit einem separaten Gerät. Bei einem solchen separaten Gerät handelt es sich beispielsweise um ein Steuergerät, zur Vorgabe von Hörgeräteeinstellungen, eine externe Tonsignalquelle (z. B. ein Smartphone, ein TV-Gerät oder dergleichen) oder um ein zweites Hörgerät, das zur binauralen Versorgung beider Ohren des Hörgeräteträgers eingerichtet und vorgesehen ist. Die Antenne ist in diesem Fall insbesondere in das erste und/oder das zweite Dämpfungselement, bevorzugt aber in das aus dem ersten und dem zweiten Dämpfungselement gebildete Dämpferteil integriert. Beispielsweise ist die Antenne als metallisches Einlegeteil in dieses Dämpferteil, insbesondere in dessen Verbindungssteg eingespritzt (d. h. mit dem Kunststoff des ersten und zweiten Dämpfungselements umspritzt). Dadurch wird eine Funktionsintegration mehrerer separater Bauelemente des Hörgeräts in ein Bauteil erreicht und somit die Handhabung der Bauteile bei der Montage vereinfacht.In a further expedient embodiment, the hearing device comprises an antenna for electromagnetic (in particular radio-technical) communication with a separate device. Such a separate device is for example an external audio signal source (for example a smartphone, a TV set or the like) or a second hearing device which is set up and provided for the binaural supply of both ears of the hearing device wearer. In this case, the antenna is integrated in particular in the first and / or the second damping element, but preferably in the damper part formed from the first and the second damping element. For example, the antenna is injected as a metallic insert part in this damper part, in particular in the connecting web (ie encapsulated with the plastic of the first and second damping element). Characterized a functional integration of several separate components of the hearing aid is achieved in a component and thus simplifies the handling of the components during assembly.
In einer weiteren zweckmäßigen Ausführung umfasst das Hörgerät einen Schaltungsträger, der insbesondere eine Signalverarbeitungseinheit zur Auswertung und Verstärkung der erfassten akustischen Signale sowie Leiterbahnen zur elektrischen Kontaktierung des ersten Mikrophons sowie gegebenenfalls des zweiten Mikrophons und der Antenne mit der Signalverarbeitungseinheit trägt. Die Antenne ist hierbei vorzugsweise mittels einer Lötverbindung mit einer ihr zugeordneten Leiterbahn des Schaltungsträgers verbunden. Alternativ ist die Antenne mittels einer Steckverbindung, einer Klemmverbindung, einem Federkontakt o. dgl. mit der entsprechenden Leiterbahn kontaktiert.In a further expedient embodiment, the hearing device comprises a circuit carrier, which carries in particular a signal processing unit for evaluating and amplifying the detected acoustic signals and tracks for electrical contacting of the first microphone and optionally the second microphone and the antenna with the signal processing unit. The antenna is in this case preferably connected by means of a solder connection with an associated conductor track of the circuit carrier. Alternatively, the antenna is contacted by means of a plug connection, a clamp connection, a spring contact o. The like. With the corresponding conductor track.

Um ein Eindringen von Verunreinigungen, konkret von Flüssigkeit wie z. B. Wasser oder Körperschweiß durch die beiden Mikrophonöffnungen 18 und 20 zu verhindern und somit die beiden Mikrophone 2 und 3 vor Verschmutzung und Feuchtigkeit zu schützen, umfasst das Hörgerät 1 des Weiteren zwei (dem jeweiligen Mikrophon 2 bzw. 3 zugeordnete) Barriereelemente 22 und 24. Diese Barriereelemente 22 und 24 sind dabei jeweils reversibel (d. h. austauschbar) in dem jeweiligen Dämpfungselement 14 bzw. 16 gehaltert. Die Abdichtung des jeweiligen Barrierelements 20 bzw. 24 gegenüber dem Gehäuse 10, konkret dem Deckel 12, erfolgt dabei über das jeweilige Dämpfungselement 14 und 16.In order to prevent the ingress of contaminants, specifically of liquid such.

Der Rand 34 des Dämpfungselements 14 bzw. 16 ist derart gestaltet, dass er im Bezug auf den Außendurchmesser des (kreisförmigen) Barriereelements 22 bzw. 24 lediglich geringfügig über dessen Rahmen 28 übersteht. Dadurch kann zur Montage oder Demontage das Barriereelement 22 bzw. 24 unter Überwindung der elastischen Rückstellkraft des Randes 34 (d. h. unter geringfügiger elastischer Deformation desselben) in den Hinterschnitt 32 eingeschoben werden, wobei der Rand 34 über den Rahmen 28 "aufschnappt".The

Der Hinterschnitt 32 wird somit in Richtung auf die Mikrophonöffnung 18 bzw. 20 (im Folgenden als Vorderseite des jeweiligen Dichtungselements 14 bzw. 16 bezeichnet) von dem Rand 34 begrenzt. Rückseitig wird der Hinterschnitt 32 von einem weiteren, den Durchbruch 30 sowie das Dämpfungselement 14 bzw. 16 abschließenden Rand 38 begrenzt. Der Rand 38 weist gleichermaßen wie der Rand 34 eine im Vergleich zur Länge des Durchbruchs 30 geringe Wanddicke auf. Im Ausführungsbeispiel gemäß
