Definitions
- the present invention relates to a chin strap headphones with two acoustic transducers and with two brackets, at the upper end of each of which one of the transducers is fixed and whose upper ends are elastically removable from each other and which are interconnected at their lower end.
- Headphones are known to be designed in particular as chin-earphones when boards with electrical circuits are to be attached to the headphones.
- Known chin-ear headphones have for this purpose a small housing which can be positioned under the chin in front of the user's chest and from which two elastic straps lead in a slightly curved course past the cheeks to the ears.
- There at the upper ends of the strap acoustic transducers are mounted.
- the transducers are usually equipped with ear pads that cushion the contact pressure of the transducer against the ears for the user comfortably and softly.
- the contact pressure is generated by the fact that the upper ends of the strap with the transducers away from each other while the strap on their Length are elastically deformed transversely, so that then placed in the earcups of the user ear pads of the acoustic transducer are resiliently pressed into the ears, find support there and ensure a good acoustic transmission.
- the entire weight of chin strap headphones is stored in the user's pressure sensitive earcups. So that the chin-earphone headphone does not slip from the user's ears by its own weight, or at the latest with slight movements of the head, the spring characteristics of the elastically laterally deformable brackets as well as the initial undeflected distance between the brackets before applying the chin guard Headphone so matched by the user, that adjusts the deflection of the bracket by inserting the transducer pad in the ears, a sufficiently large contact pressure.
- chin strap headphones may tend to slip off the ears while the same chin strap headphones will cause unpleasant ear pressure to a user with a broad head.
- the invention is therefore an object of the invention to provide a chin strap headphones, regardless of individual dimensions of the head anatomy of his user ensures a contact pressure of the acoustic transducer against the ear cups, which is strong enough for a secure fit and sufficiently weak to the user not to be uncomfortable.
- a chin strap headphones has two acoustic transducers each for one ear and two stirrups, at the upper end of each of which one of the transducers is attached to the ear for positioning.
- the brackets are connected together at their lower end and together form a bay, which then, when a user applies the chin strap headphones, passes from one ear to the other under the user's chin.
- the upper ends of the strap can be used to generate contact pressure of the transducer - preferably by padding between transducer and ear for the user more convenient on a larger surface of the pinnae removed elastically from each other, preferably, by the strap over its length are elastically deformed transversely.
- the distance between the upper ends of the straps - that is the distance between the ear contact surfaces of the transducers - adjustable at the connection of the lower ends of the strap, in particular before the chin strap headphones is applied by a user .
- the spring travel of the bracket which, as described with respect to the prior art, generates the contact pressure of the transducer against the ears, can be adjusted to the individual width of the head of the user (the distance of his auricles from each other and there in particular the surface areas, who are in contact with the transducers when the receiver is connected).
- the bias of the elastically removable upper ends of the strap against the ears of the user changes by changing the resilient deflection of the bracket, and thus according to the invention the contact pressure of the transducer (or preferably attached to the transducers pad) against the adjustable pressure-sensitive earcups of the user.
- a hinge joint forms the connection between the lower 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 bracket, where the transducers are mounted.
- the stirrups are movable from a low-angle rest position between the stirrups and a slight distance between their upper ends to a larger-angle functional position between the stirrups and greater distance between their upper ends, and a spring in the region of the connection biases the stirrups in the direction of the rest position against each other.
- the chin-earphone headset according to the invention moves in a spring-actuated manner into the space-saving rest position when the brackets are not actuated and moved apart by a user.
- the movement of the bracket is limited in the direction of the functional position by a stop which is adjustable for adjusting the distance between the upper ends of the bracket according to the invention.
- the angular position of the stopper is adjustable so that the moving in the operating position against the stop bracket assume an adjustable angle by means of the stop, the distance between the transducers at the upper end of the bracket on the adjustment of the stop is adjustable according to the invention.
- the user moves the bracket from the rest position against the bias of the spring - which preferably has a relatively small spring constant - up against the adjustable stop in the operating position. It now bends the upper ends apart so that the straps elastically deform over their length, preferably with a greater spring constant than the spring, and then inserts the acoustic transducers at the top of the straps into its ears. If the user now finds that the bias of the strap against his ears is too low, he adjusts the stop in the direction of a smaller angle between the brackets to the resilient deflection of the strap - so the contact pressure - against his ears at his head between the Ironing to enlarge.
- the spring pulls the brackets in the rest position, thereby characterized in the rest position, a button, for example. to turn off the headset is pressed.
- a chin guard headphones with two brackets 2 and two acoustic transducers 4 at the upper end of the bracket 2 can be seen.
- the brackets 2 are connected to one another at a housing 6 and thus form an upwardly open bay.
- the bracket 2 arcuately arched outwards, and the acoustic transducers 4 at the upper end of the bracket 2 are directed inwardly with ear pads 8, which also point inwardly into the bay thus formed.
- the ear pads 8 (made of rubber or elastic plastic) each have a passage 10 of two crossed slots to ensure a good acoustic connection from the transducers 4 through the ear pads 8 in the direction of the ears (not shown).
- bracket 2 with the acoustic transducers 4 and the ear pads 8 are elastically removable from each other by the bracket 2 are elastically deformable over its arcuate length transversely outwardly.
- the bay formed by the brackets 2 can be elastically expanded, and the ear pads 8 on the acoustic transducers 4 can be inserted by the user in his ears, the brackets 2 along the cheeks of the user down to the chin, where under the chin the housing 6 rests as a connection between the lower ends of the brackets 2 on the chest (not shown) of the user.
- the left of the bracket 2 is inserted in a shaft 12 which is integrally connected to a cover 14 which forms the rear wall of the circular cylindrical housing 6.
- a tension coil spring 18 with respect to the axis 16 in the circumferential direction between the right of the bracket 2 and the circumference of the housing 6 forming wall of the housing 6 is biased counterclockwise about the axis 16.
- the spring 18 pulls the right of the bracket 2 with a projection 22 which is formed on the right of the bracket 2, counterclockwise against a button (not shown) to turn off the headphone.
- the button is disposed on a board (not shown) which is in a plane perpendicular to the axis 16 above the elements described herein in the housing 6.
- the right of the bracket 2 is thus articulated in the housing 6 on the coaxial with it axis 16 and thus can pivotally take two different angles to the left of the bracket 2.
- the right of the bracket 2 can sweep at an angle of approximately 15 ° with respect to the housing 6 pivotally, by the right of the bracket 2 is guided out of the housing 6 through a correspondingly wide slot 24 in the peripheral wall of the housing 6 to the outside.
- 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 opposite direction the spring pulls 18 to the right of the bracket 2 in the Rest position, in which the projection 22, the button (not shown) is pressed.
- the extreme position of the right of the bracket 2 in the clockwise direction in the circumferential direction of the housing 6 - the position in which a user pulls the bracket 2 apart to apply the headphones - is adjustable by a likewise mounted on the axis 16 adjustment lever 26.
- the lever 26, with which the pin 28 in the slot 30 is pivotable about the axis 16 together, is limited in its pivoting range by a screw 32 which is inserted through a hole in the lever 26 on the one hand and through a second slot 34 on the other hand, 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, with the screw 32 tightened the lever 26 - set around the axis 16 around - set.
- the pin 28 is pivotally adjustable as part of the lever 26 in the slot 30 of the right of the bracket 2 and serves as a stop of the right of the bracket 2 about the axis 16 around to limit the mobility of the right of the bracket 2 in a clockwise direction. Then namely the edge of the slot 30 as part of the right of the bracket 2 abuts against the pin 28 as part of the lever 26 at.
- the mobility of the right of the bracket 2 relative to the left of the bracket 2 is adjustable adjustable limited by the described embodiment in that the ends of the stirrups 2 can only be removed from each other as far as an adjustable distance as described before the stirrups 2 deform elastically - ie resiliently - transversely and by this deformation the contact pressure of the ear cushions 8 against the auricles (not shown) of the user produce.
- This contact pressure is consequently by the described adjustability of the mobility of the bracket 2 against each other adjustable by individually adjustable by fixing the position of the bracket 2 to each other in front of their resilient deflection of travel of the bracket to the bracket 2 by the individual ear distance of a headset user be deflected.
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 upper end of each of which one of the transducers is fixed and whose upper ends are elastically removable from each other and which are interconnected 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 designed in particular as chin-earphones when boards with electrical circuits are to be attached to the headphones. Known chin-ear headphones have for this purpose a small housing which can be positioned under the chin in front of the user's chest and from which two elastic straps lead in a slightly curved course past the cheeks to the ears. There at the upper ends of the strap acoustic transducers are mounted. The transducers are usually equipped with ear pads that cushion the contact pressure of the transducer against the ears for the user comfortably and softly. The contact pressure is generated by the fact that the upper ends of the strap with the transducers away from each other while the strap on their Length are elastically deformed transversely, so that then placed in the earcups of the user ear pads of the acoustic transducer are resiliently pressed into the ears, find support there and ensure a good acoustic transmission.
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 earphones with headband straps, the entire weight of chin strap headphones is stored in the user's pressure sensitive earcups. So that the chin-earphone headphone does not slip from the user's ears by its own weight, or at the latest with slight movements of the head, the spring characteristics of the elastically laterally deformable brackets as well as the initial undeflected distance between the brackets before applying the chin guard Headphone so matched by the user, that adjusts the deflection of the bracket by inserting the transducer pad in the ears, 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.However, it is problematic that different users have individually different distances between their ears and that as a result of this individual ear distance an individually different contact pressure is established. Thus, for users with slender heads, chin strap headphones may tend to slip off the ears while the same chin strap headphones will cause unpleasant ear pressure to a user with a broad head.
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 an object of the invention to provide a chin strap headphones, regardless of individual dimensions of the head anatomy of his user ensures a contact pressure of the acoustic transducer against the ear cups, which is strong enough for a secure fit and sufficiently weak to the user not to be uncomfortable.
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 features described in
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 verteiltelastisch 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 headphones has two acoustic transducers each for one ear and two stirrups, at the upper end of each of which one of the transducers is attached to the ear for positioning. The brackets are connected together at their lower end and together form a bay, which then, when a user applies the chin strap headphones, passes from one ear to the other under the user's chin. The upper ends of the strap can be used to generate contact pressure of the transducer - preferably by padding between transducer and ear for the user more convenient on a larger surface of the pinnae removed elastically from each other, preferably, by the strap over its length are elastically deformed transversely. According to the invention, in such a chin strap earphone, the distance between the upper ends of the straps - that is the distance between the ear contact surfaces of the transducers - adjustable at the connection of the lower ends of the strap, in particular before the chin strap headphones is applied by a user , In this way, the spring travel of the bracket, which, as described with respect to the prior art, generates the contact pressure of the transducer against the ears, can be adjusted to the individual width of the head of the user (the distance of his auricles from each other and there in particular the surface areas, who are in contact with the transducers when the receiver is connected). When this setting is made with the inventive chin strap headphones, although not the distance between the transducers at the upper end of the bracket changes, because of course with given chin strap headphones by the distance of the ears given, but- and that is the same The object underlying the invention - the bias of the elastically removable upper ends of the strap against the ears of the user changes by changing the resilient deflection of the bracket, and thus according to the invention the contact pressure of the transducer (or preferably attached to the transducers pad) against the adjustable pressure-sensitive earcups of the user.
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.Preferably, a hinge joint forms the connection between the lower 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 bracket, where the transducers are mounted.
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. Die Bewegung der Bügel ist 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.At the hinge joint, the stirrups are movable from a low-angle rest position between the stirrups and a slight distance between their upper ends to a larger-angle functional position between the stirrups and greater distance between their upper ends, and a spring in the region of the connection biases the stirrups in the direction of the rest position against each other. As a result, the chin-earphone headset according to the invention moves in a spring-actuated manner into the space-saving rest position when the brackets are not actuated and moved apart by a user. The movement of the bracket is limited in the direction of the functional position by a stop which is adjustable for adjusting the distance between the upper ends of the bracket according to the invention. By namely, the angular position of the stopper is adjustable so that the moving in the operating position against the stop bracket assume an adjustable angle by means of the stop, the distance between the transducers at the upper end of the bracket on the adjustment of the stop is adjustable according to the invention.
Der Benutzer bewegt 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 elastischmit 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 moves the bracket from the rest position against the bias of the spring - which preferably has a relatively small spring constant - up against the adjustable stop in the operating position. It now bends the upper ends apart so that the straps elastically deform over their length, preferably with a greater spring constant than the spring, and then inserts the acoustic transducers at the top of the straps into its ears. If the user now finds that the bias of the strap against his ears is too low, he adjusts the stop in the direction of a smaller angle between the brackets to the resilient deflection of the strap - so the contact pressure - against his ears at his head between the Ironing to enlarge.
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 he uncomfortably press the transducer uncomfortably in the ears, he adjusted accordingly the stop in the direction of the larger angle between the brackets to their relaxation.
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.Preferably, the spring pulls the brackets in the rest position, thereby characterized in the rest position, a button, for example. to turn off the headset is pressed.
Die Erfindung wird im folgenden mit Bezug auf die beigefügte Figur beschrieben.
- Die Figur
- zeigt eine Vorderansicht eines erfindungsgemäßen Kinnbügel-Kopf- hörers, bei dessen Schaltungsgehäuse der abgenommene, nicht dargestellte Deckel den Blick in das Gehäuse freilässt.
- The figure
- shows a front view of a chin-earphone according to the invention, in the circuit housing of the removed, not shown lid leaves open the view into the housing.
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, a chin guard headphones with two
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
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
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
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.
