Description

Die vorliegende Erfindung betrifft einen Kinnbügel-Kopfhörer mit zwei akustischen Wandlern und mit zwei Bügeln, an deren oberem Ende jeweils einer der Wandler befestigt ist und deren obere Enden elastisch voneinander entfernbar sind und die an ihrem unteren Ende miteinander verbunden sind.The present invention relates to a chin strap headphones with two acoustic Transducers and with two brackets, at the top of each one of the transducers is attached and the upper ends are elastically removable from each other and the are connected together at their lower end.

Kopfhörer werden bekannterweise insbesondere dann als Kinnbügel-Kopfhörer ausgestaltet, wenn Platinen mit elektrischen Schaltungen am Kopfhörer angebracht sein sollen. Bekannte Kinnbügel-Kopfhörer weisen dazu ein kleines Gehäuse auf, welches unter dem Kinn vor der Brust des Benutzers positionierbar ist und von dem ausgehend zwei elastische Bügel in leicht bogenförmigem Verlauf an den Wangen vorbei zu den Ohren führen. Dort an den oberen Enden der Bügel sind akustische Wandler angebracht. Die Wandler sind üblicherweise mit Ohrpolstern bestückt, die den Anpressdruck der Wandler gegen die Ohren für den Benutzer bequem und weich abfedern. Der Anpressdruck wird dadurch erzeugt, dass die oberen Enden der Bügel mit den Wandlern voneinander entfernt und dabei die Bügel über ihre Länge elastisch quer verformt werden, so dass die dann in den Ohrmuscheln des Benutzers platzierten Ohrpolster der akustischen Wandler federnd leicht in die Ohren eingedrückt werden, dort Halt finden und eine gute akustische Übertragung gewährleisten,Headphones are known to be used especially as chin guard headphones designed when circuit boards with electrical circuits attached to the headphones should be. Known chin strap headphones have a small housing, which can be positioned under the chin in front of the user's chest and from which starting from two elastic temples in a slightly curved shape on the cheeks lead past to the ears. There at the top ends of the brackets are acoustic Transducer attached. The transducers are usually equipped with ear pads that the pressure of the transducers against the ears for the user comfortably and cushion softly. The contact pressure is generated by the upper ends the bracket with the transducers apart and the bracket over their Length can be elastically deformed transversely, so that the then in the auricles of the User placed the ear pads of the acoustic transducers bouncy lightly into the Ears are pressed in, find a stop there and good acoustic transmission guarantee,

Anders als bei Kopfhörern mit über dem Kopf verlaufenden Bügeln lagert das gesamte Gewicht von Kinnbügel-Kopfhörern in den druckempfindlichen Ohrmuscheln des Benutzers. Damit aber der Kinnbügel-Kopfhörer dem Benutzer nicht schon bloß durch sein Eigengewicht, oder aber spätestens bei leichten Bewegungen des Kopfes von den Ohren rutscht, sind die Federkennlinien der elastisch seitlich verformbaren Bügel sowie der anfängliche nicht ausgelenkte Abstand der Bügel vor dem Anlegen des Kinnbügel-Kopfhörers durch den Benutzer so aufeinander abgestimmt, dass bei der Auslenkung der Bügel durch das Einsetzen der Wandlerpolster in die Ohren sich ein genügend großer Anpressdruck einstellt.Unlike headphones with temples running over the head, this is stored total weight of chin strap headphones in the pressure sensitive ear cups of the user. But that does not mean the chin strap headphones to the user just by its own weight, or at the latest with slight movements of the head slips off the ears, the spring characteristics are elastic laterally deformable bracket and the initial undeflected distance of the Brackets before the user puts on the chin guard headphones matched that when the bracket is deflected by inserting the Transducer pads in the ears there is a sufficiently large contact pressure.

Problematisch ist nun aber, dass verschiedene Benutzer individuell verschiedene Abstände zwischen ihren Ohren haben und dass sich dadurch abhängig von diesem individuellen Ohrabstand ein individuell unterschiedlicher Anpressdruck einstellt. Bei Benutzern mit schmalen Köpfen kann folglich ein Kinnbügel-Kopfhörer dazu neigen, von den Ohren zu rutschen, während derselbe Kinnbügel-Kopfhörer bei einem Benutzer mit breitem Kopf einen unangenehmen Ohrdruck verursacht.The problem now, however, is that different users have individually different ones Have gaps between their ears and that this depends on this individual ear distance sets an individually different contact pressure. at As a result, users with narrow heads may have chin strap headphones slip off your ears while wearing the same chin strap headphones Wide-headed user causes uncomfortable ear pressure.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Kinnbügel-Kopfhörer zu schaffen, der unabhängig von individuellen Dimensionen der Kopfanatomie seines Benutzers einen Anpressdruck der akustischen Wandler gegen die Ohrmuscheln gewährleistet, der genügend stark für einen sicheren Halt und genügend schwach ist, um von dem Benutzer nicht unangenehm empfunden zu werden.The invention is therefore based on the object of a chin strap headphones create that regardless of individual dimensions of the head anatomy of his User presses the acoustic transducer against the ear cups ensures that is strong enough for a secure hold and weak enough is so as not to be uncomfortable for the user.

Diese Aufgabe wird erfindungsgemäß von einem Kinnbügel-Kopfhörer mit den in Anspruch 1 beschriebenen Merkmalen gelöst. Bevorzugte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. This object is achieved by a chin strap headphones with the in Features described claim 1 solved. Preferred embodiments of the Invention are specified in the subclaims.

Erfindungsgemäß hat ein Kinnbügel-Kopfhörer zwei akustische Wandler jeweils für ein Ohr und zwei Bügel, an deren oberem Ende zur Positionierung am Ohr jeweils einer der Wandler befestigt ist. Die Bügel sind an ihrem unteren Ende miteinander verbunden und bilden so zusammen eine Bucht, die dann, wenn ein Benutzer den Kinnbügel-Kopfhörer anlegt, von einem Ohr zum anderen unter dem Kinn des Benutzers hindurchführt. Die oberen Enden der Bügel lassen sich zum Erzeugen von Anpressdruck der Wandler - vorzugsweise durch Polster zwischen Wandler und Ohr für den Benutzer bequemer auf eine größere Fläche der Ohrmuscheln verteilt-elastisch voneinander entfernen, und zwar vorzugsweise, indem die Bügel über ihre Länge elastisch quer verformbar sind. Erfindungsgemäß ist bei einem solchen Kinnbügel-Kopfhörer der Abstand zwischen den oberen Enden der Bügel - also der Abstand zwischen den Ohrkontaktflächen der Wandler - an der Verbindung der unteren Enden der Bügel einstellbar, und zwar insbesondere, bevor der Kinnbügel-Kopfhörer von einem Benutzer angelegt wird. Auf diese Weise lässt sich der Federweg der Bügel, der, wie bezüglich des Standes der Technik beschrieben, den Anpressdruck der Wandler gegen die Ohren erzeugt, auf die individuelle Breite des Kopfes des Benutzers einstellen (den Abstand seiner Ohrmuscheln voneinander und dort insbesondere der Flächenbereiche, die bei angelegtem Hörer im Kontakt zu den Wandlern stehen). Wenn diese Einstellung bei angelegtem erfindungsgemäßem Kinnbügel-Kopfhörer vorgenommen wird, verändert sich zwar nicht der Abstand zwischen den Wandlern am oberen Ende der Bügel, denn der ist bei angelegtem Kinnbügel-Kopfhörer natürlich durch den Abstand der Ohren vorgegeben, aber-und auch das entspricht dem der Erfindung zugrundeliegenden Ziel - die Vorspannung der elastisch voneinander entfernbaren oberen Enden der Bügel gegen die Ohrmuscheln des Benutzers verändert sich durch Änderung der federnden Auslenkung der Bügel, und somit ist erfindungsgemäß der Anpressdruck der Wandler (oder der vorzugsweise auf den Wandlern angebrachten Polster) gegen die druckempfindlichen Ohrmuscheln des Benutzers einstellbar.According to the invention, a chin strap headphone has two acoustic transducers for each one ear and two brackets, at their upper ends for positioning on the ear each one of the transducers is attached. The brackets are together at their lower ends connected and thus together form a bay which, when a user accesses the Chin strap headphones put on from ear to ear under the chin Leads through. The upper ends of the brackets can be used to create Contact pressure of the transducers - preferably through pads between the transducer and the ear more elastic for the user spread over a larger area of the ear cups away from each other, preferably by placing the brackets over their Length are elastically deformable transversely. According to the invention is in such a Chin strap headphones the distance between the top ends of the temples - i.e. the Distance between the ear contact surfaces of the transducers - at the connection of the adjustable lower ends of the temples, especially before the chin strap headphones is created by a user. In this way, the Travel of the bracket, which, as described in relation to the prior art, the The transducer presses against the ears to the individual width of the Adjust the user's head (the distance of his ear cups from each other and there in particular the surface areas that are in contact with the listener when the handset is on Converters). If this setting with the invention Chin strap headphones, the distance does not change between the transducers at the upper end of the bracket, because this is when the Chin strap headphones of course dictated by the distance between the ears, but-and this also corresponds to the goal on which the invention is based - the preload the elastically removable upper ends of the bracket against the The user's ear cups change by changing the spring deflection the bracket, and thus the contact pressure according to the invention is the transducer (or the pads, which are preferably attached to the transducers) against the pressure-sensitive ones User adjustable ear cups.

Vorzugsweise bildet ein Scharniergelenk die Verbindung zwischen den unteren Enden der Bügel, welches in beliebigem Öffnungswinkel arretierbar ist. So ergibt sich eine einstellbare Weite der von den Bügeln gebildeten Bucht und folglich erfindungsgemäß ein einstellbarer Abstand zwischen den oberen Enden der Bügel, wo die Wandler befestigt sind.A hinge joint preferably forms the connection between the lower ones Ends of the bracket, which can be locked in any opening angle. So results an adjustable width of the bay formed by the brackets and consequently according to the invention an adjustable distance between the upper ends of the brackets, where the transducers are attached.

Zum Beispiel an dem Scharniergelenk sind die Bügel aus einer Ruheposition mit geringem Winkel zwischen den Bügeln und geringem Abstand zwischen deren oberen Enden in eine Funktionsposition mit größerem Winkel zwischen den Bügeln und größerem Abstand zwischen deren oberen Enden bewegbar, und eine Feder im Bereich der Verbindung spannt die Bügel in Richtung der Ruheposition gegeneinander vor. Dadurch fährt der erfindungsgemäße Kinnbügel-Kopfhörer federbetätigt in die platzsparende Ruheposition, wenn die Bügel nicht von einem Benutzer betätigt und auseinanderbewegt werden. Vorzugsweise ist die Bewegung der Bügel in Richtung der Funktionsposition durch einen Anschlag begrenzt, der zum erfindungsgemäßen Einstellen des Abstandes zwischen den oberen Enden der Bügel einstellbar ist. Indem nämlich die Winkelposition des Anschlags so einstellbar ist, dass die in der Funktionsposition gegen den Anschlag bewegten Bügel einen mittels des Anschlags einstellbaren Winkel zueinander einnehmen, ist erfindungsgemäß auch der Abstand zwischen den Wandlern am oberen Ende der Bügel über die Verstellung des Anschlags einstellbar.For example on the hinge joint, the brackets are from a rest position small angle between the brackets and small distance between them upper ends in a functional position with a larger angle between the brackets and greater distance between their upper ends movable, and a spring in The area of the connection clamps the brackets towards each other in the direction of the rest position in front. As a result, the chin strap headphones according to the invention are spring-actuated in the space-saving rest position when the bracket is not in use by a user operated and moved apart. The movement of the stirrups is preferred limited in the direction of the functional position by a stop that is to the invention Adjust the distance between the top ends of the brackets is adjustable. Because the angular position of the stop is so adjustable, that the bracket moved against the stop in the functional position Taking adjustable angles to each other by means of the stop is according to the invention also the distance between the transducers at the top of the bracket the adjustment of the stop adjustable.

Der Benutzer bewegt also bei dieser bevorzugten Ausführungsform des erfindungsgemäßen Kinnbügel-Kopfhörers die Bügel aus der Ruheposition gegen die Vorspannung der Feder - die vorzugsweise eine vergleichsweise kleine Federkonstante hat - bis gegen den einstellbaren Anschlag in die Funktionsposition. Er biegt nun die oberen Enden auseinander, so dass sich die Bügel über ihre Länge elastisch-mit vorzugsweise größerer Federkonstante als die Feder - quer verformen, und setzt dann die akustischen Wandler am oberen Ende der Bügel in seine Ohren ein. Wenn der Benutzer nun feststellt, dass die Vorspannung der Bügel gegen seine Ohren zu gering ist, verstellt er den Anschlag in Richtung eines kleineren Winkels zwischen den Bügeln, um die federnde Auslenkung der Bügel - also den Anpressdruck - gegen seine Ohren an seinem Kopf zwischen den Bügeln zu vergrößern. The user therefore moves in this preferred embodiment of the invention Chin strap headphones from the rest position against the bias the spring - which is preferably a comparatively small spring constant has - up to the adjustable stop in the functional position. He is now bending the upper ends apart so that the brackets are elastic along with their length preferably larger spring constant than the spring - deform transversely, and then places the acoustic transducers in his ears at the top of the bracket. If the user now finds that the bracket is preloaded against its Ears too small, he moves the stop towards a smaller angle between the brackets, around the resilient deflection of the brackets - i.e. the contact pressure - enlarge against his ears on his head between the temples.

Oder wenn ihm die Wandler unangenehm stark in die Ohren drücken, verstellt er dementsprechend den Anschlag in Richtung des größeren Winkels zwischen den Bügeln zu deren Entspannung.Or if the transducers push him uncomfortably hard in the ears, he adjusts accordingly the stop in the direction of the larger angle between the Iron to relax them.

Vorzugsweise zieht die Feder die Bügel so in die Ruheposition, dass dadurch in der Ruheposition ein Taster z.B. zum Ausschalten des Kopfhörers betätigt ist.The spring preferably pulls the stirrups into the rest position in such a way that in the Rest position a button e.g. is pressed to switch off the headphones.

Die Erfindung wird im folgenden mit Bezug auf die beigefügte Figur beschrieben.

Die Figur
zeigt eine Vorderansicht eines erfindungsgemäßen Kinnbügel-Kopfhörers, bei dessen Schaltungsgehäuse der abgenommene, nicht dargestellte Deckel den Blick in das Gehäuse freilässt.
The invention is described below with reference to the accompanying figure.
The figure

Mit Bezug auf die Figur ist ein Kinnbügel-Kopfhörer mit zwei Bügeln 2 und zwei akustischen Wandlern 4 am oberen Ende der Bügel 2 erkennbar. An ihrem unteren Ende sind die Bügel 2 an einem Gehäuse 6 miteinander verbunden und bilden so eine nach oben offene Bucht. Dabei sind die Bügel 2 bogenförmig nach außen gewölbt, und die akustischen Wandler 4 am oberen Ende der Bügel 2 sind nach innen gerichtet mit Ohrpolstern 8, die ebenfalls nach innen in die so gebildete Bucht weisen. An ihren innenseitigen Spitzen weisen die Ohrpolster 8 (aus Gummi oder elastischem Kunststoff) jeweils einen Durchgang 10 aus zwei gekreuzten Schlitzen auf, um eine gute akustische Verbindung von den Wandlern 4 durch die Ohrpolster 8 in Richtung der Ohren (nicht dargestellt) zu gewährleisten.With reference to the figure is a chin strap headphones with two straps 2 and two acoustic transducers 4 recognizable at the upper end of the bracket 2. At her bottom The brackets 2 are connected to one another at a housing 6 and thus form a bay open to the top. The brackets 2 are arched outwards arched, and the acoustic transducers 4 at the top of the bracket 2 are after directed inside with ear cushions 8, which are also formed in the inside Bay show. The ear pads 8 (made of rubber or elastic plastic) each have a passage 10 of two crossed Slits on to make a good acoustic connection from the transducers 4 through the To ensure ear pads 8 in the direction of the ears (not shown).

Die oberen Enden der Bügel 2 mit den akustischen Wandlern 4 und den Ohrpolstern 8 sind elastisch voneinander entfernbar, indem die Bügel 2 über ihre bogenförmige Länge quer nach außen elastisch verformbar sind. Somit lässt sich die von den Bügeln 2 gebildete Bucht elastisch aufweiten, und die Ohrpolster 8 an den akustischen Wandlern 4 lassen sich vom Benutzer in seine Ohren einsetzen, wobei die Bügel 2 entlang der Wangen des Benutzers nach unten zum Kinn führen, wo unter dem Kinn das Gehäuse 6 als Verbindung zwischen den unteren Enden der Bügel 2 auf der Brust (nicht dargestellt) des Benutzers ruht. The upper ends of the bracket 2 with the acoustic transducers 4 and the ear pads 8 are elastically removable from each other by the bracket 2 over their arcuate Length are elastically deformable transversely to the outside. Thus, that of the Iron 2 formed bay expand elastically, and the ear pads 8 on the acoustic Transducers 4 can be used by the user in his ears, the Guide bracket 2 along the user's cheeks down to the chin where under the chin the housing 6 as a connection between the lower ends of the bracket 2nd rests on the user's chest (not shown).

Der linke der Bügel 2 steckt in einem Schaft 12, der einstückig mit einem Deckel 14 verbunden ist, welcher die Rückwand des kreiszylinderförmigen Gehäuses 6 bildet. An einer mit dem Gehäuse 6 koaxialen Achse 16 ist über ein Scharniergelenk der rechte der Bügel 2 angelenkt und so mit dem linken der Bügel 2 durch das Gehäuse 6 verbunden. Im Innenraum des Gehäuses 6 ist eine Zugschraubenfeder 18 bezüglich der Achse 16 in Umfangsrichtung zwischen dem rechten der Bügel 2 und der den Umfang des Gehäuses 6 bildenden Wandung des Gehäuses 6 gegen den Uhrzeigersinn um die Achse 16 vorgespannt. Dabei zieht die Feder 18 den rechten der Bügel 2 mit einem Vorsprung 22, der auf dem rechten der Bügel 2 ausgebildet ist, gegen den Uhrzeigersinn gegen einen Taster (nicht dargestellt) zum Ausschalten des Kopfhörers. Der Taster ist auf einer Platine (nicht dargestellt) angeordnet, welche sich in einer zu der Achse 16 senkrechten Ebene über den hier beschriebenen Elementen in dem Gehäuse 6 befindet.The left of the bracket 2 is in a shaft 12, the one piece with a lid 14, which is the rear wall of the circular-cylindrical housing 6 forms. On an axis 16 coaxial with the housing 6 is via a hinge joint the right of the bracket 2 articulated and so with the left of the bracket 2 through the Housing 6 connected. In the interior of the housing 6 is a tension coil spring 18 with respect to the axis 16 in the circumferential direction between the right of the bracket 2 and the wall of the housing 6 forming the periphery of the housing 6 against biased clockwise about axis 16. The spring 18 pulls the the bracket 2 on the right with a projection 22 which is on the bracket 2 on the right is formed, counterclockwise against a button (not shown) for Turn off the headphones. The button is on a circuit board (not shown) arranged, which is in a plane perpendicular to the axis 16 above the here described elements is located in the housing 6.

Der rechte der Bügel 2 ist also in dem Gehäuse 6 an der damit koaxialen Achse 16 angelenkt und kann somit schwenkbar zu dem linken der Bügel 2 unterschiedliche Winkel einnehmen. Dazu kann der rechte der Bügel 2 einen Winkel von ungefähr 15° bezüglich dem Gehäuse 6 schwenkbar überstreichen, indem der rechte der Bügel 2 aus dem Gehäuse 6 durch ein entsprechend weites Langloch 24 in der Umfangswand des Gehäuses 6 nach außen geführt ist. Die Wandung des Langlochs 24 dient dabei als Anschlag und Begrenzung für den Bewegungsbereich des rechten der Bügel 2 gegenüber dem linken der Bügel 2 in Umfangsrichtung des Gehäuses 6. In die Extremlage dieses Bewegungsbereichs gegen den Uhrzeigersinn zieht die Feder 18 den rechten der Bügel 2 in die Ruheposition, in der der Vorsprung 22 den Taster (nicht dargestellt) betätigt.The right of the bracket 2 is thus articulated in the housing 6 on the axis 16 coaxial therewith and can thus pivot differently from the left of the bracket 2 at different angles. For this purpose, the right of the bracket 2 can swivel over an angle of approximately 15 ° with respect to the housing 6 by the right of the bracket 2 being guided out of the housing 6 through a correspondingly long slot 24 in the peripheral wall of the housing 6. The wall of the elongated hole 24 serves as a stop and limit the range of movement of the right of the strap 2 against the left of the brackets 2 in the circumferential direction of the housing 6. In the extreme position of this movement range the counterclockwise direction, the spring 18 pulls the right hand of the brackets 2 in the Rest position in which the projection 22 actuates the button (not shown).

Die Extremposition des rechten der Bügel 2 im Uhrzeigersinn in Umfangsrichtung des Gehäuses 6 - die Lage also, in die ein Benutzer die Bügel 2 auseinanderzieht, um den Kopfhörer anzulegen - ist einstellbar durch einen ebenfalls an der Achse 16 gelagerten Einstellhebel 26. Dieser weist dazu einen Zapfen 28 auf, der in ein sich in der Umfangsrichtung um die Achse 16 erstreckendes Langloch 30 hineingreift, das am Bügel 2 innerhalb des Gehäuses 6 ausgebildet ist. Der Hebel 26, mit dem zusammen der Zapfen 28 in dem Langloch 30 um die Achse 16 schwenkbar ist, ist in seinem Schwenkbereich von einer Schraube 32 begrenzt, die einerseits durch eine Bohrung in dem Hebel 26 und andererseits durch ein zweites Langloch 34 gesteckt ist, welches sich am Gehäuse 6 ebenfalls in der Umfangsrichtung erstreckt. Der Kopf der Schraube 32 erstreckt sich aus dem Gehäuse 6 heraus und lässt sich daher von außen betätigen, um bei angezogener Schraube 32 den Hebel 26 - um die Achse 16 herum einstellbar - festzusetzen. Durch diese Ausgestaltung ist der Zapfen 28 als Teil des Hebels 26 in dem Langloch 30 des rechten der Bügel 2 einstellbar schwenkbar und dient dort als Anschlag des rechten der Bügel 2 um die Achse 16 herum zur Begrenzung der Bewegbarkeit des rechten der Bügel 2 im Uhrzeigersinn. Dann nämlich schlägt der Rand des Langlochs 30 als Teil des rechten der Bügel 2 gegen den Zapfen 28 als Teil des Hebels 26 an. Und weil der Hebel 26 mittels der Schraube 32 in dem Gehäuse 6 festgesetzt ist, welches wiederum fest mit dem linken der Bügel 2 fest verbunden ist, wird durch die beschriebene Ausgestaltung die Bewegbarkeit des rechten der Bügel 2 gegenüber dem linken der Bügel 2 dahingehend einstellbar begrenzt, dass sich die Enden der Bügel 2 nur bis zu einem wie beschrieben einstellbaren Abstand voneinander entfernen lassen, bevor sich die Bügel 2 elastisch - also federnd - quer verformen und durch diese Verformung den Anpressdruck der Ohrpolster 8 gegen die Ohrmuscheln (nicht dargestellt) des Benutzers erzeugen. Dieser Anpressdruck ist folglich durch die beschriebene Einstellbarkeit der Beweglichkeit der Bügel 2 gegeneinander einstellbar, indem durch Festlegung der Position der Bügel 2 zueinander vor ihrer federnden Auslenkung der Federweg der Bügel individuell einstellbar ist, um den die Bügel 2 durch den individuellen Ohrabstand eines Kopfhörer-Benutzers ausgelenkt werden.The extreme position of the right of the bracket 2 in a clockwise direction in the circumferential direction of the housing 6 - the position in which a user pulls the bracket 2 apart to put on the headphones - can be adjusted by means of an adjusting lever 26 which is also mounted on the axis 16 Pin 28, which engages in an elongated hole 30 extending in the circumferential direction about the axis 16, which is formed on the bracket 2 within the housing 6. The lever 26, with which the pin 28 can be pivoted about the axis 16 in the slot 30, is limited in its pivoting range by a screw 32, which is inserted on the one hand through a hole in the lever 26 and on the other hand through a second slot 34, which also extends on the housing 6 in the circumferential direction. The head of the screw 32 extends out of the housing 6 and can therefore be actuated from the outside in order to fix the lever 26 - adjustable about the axis 16 - when the screw 32 is tightened. With this configuration, the pin 28 as part of the lever 26 can be pivoted in the elongated hole 30 of the right of the bracket 2 and serves as a stop for the right of the bracket 2 around the axis 16 to limit the mobility of the right of the bracket 2 in a clockwise direction. Then namely the edge of the elongated hole 30 abuts as part of the right of the bracket 2 against the pin 28 as part of the lever 26. And because the lever 26 is fixed by means of the screw 32 in the housing 6, which in turn is firmly connected to the left of the bracket 2, the described configuration limits the movability of the right of the bracket 2 relative to the left of the bracket 2 that the ends of the brackets 2 can only be removed from one another by an adjustable distance as described before the brackets 2 are deformed elastically, i.e. resiliently, and by this deformation the contact pressure of the ear cushions 8 against the ear cups (not shown) of the user produce. This contact pressure is consequently adjustable by the described adjustability of the mobility of the stirrups 2 relative to one another, in that by determining the position of the stirrups 2 relative to one another before their resilient deflection, the spring travel of the stirrups can be individually adjusted, by which the stirrups 2 can be adjusted by the individual ear distance of a headphone user be deflected.
