The point of intersection lies on or near the center axis (Z) for each earpiece as well as in the area of the piercing point of the center axis through the contact surface (7) of the earpiece.

Description

Die Erfindung betrifft einen Kopfhörer mit einem Bügel und zwei Muscheln und insbesondere die Anpassung der Kopfhörermuschel an die unterschiedlichen Kopfformen der Benutzer und die Möglichkeit, die Kopfhörer, wenn sie nicht in Gebrauch sind, kompakt zusammenlegen zu können.The invention relates to a headphone with a bracket and two shells and in particular the adaptation of the headphone shell to the different head shapes of the users and the ability to compactly fold the headphones when not in use to be able to.

Kopfhörer sind in einer Vielzahl von Ausgestaltungen und Varianten bekannt, für die vorliegende Erfindung ist aber nicht der Aufbau und die Lagerung des Wandlers von Bedeutung, sondern nur die mechanische Verbindung und Ausgestaltung der Muscheln und des Bügels.Headphones are known in a variety of configurations and variants, for the present However, the construction and mounting of the transducer are not important to the invention, but only the mechanical connection and design of the shells and the Bracket.

Kopfhörerbügel gibt es in großer Zahl, so ist beispielsweise in der AT 370 581 B ein Kopfhörerbügel geoffenbart, der nach Art einer Nürnberger Schere aufgebaut ist und so eine ansehnliche Verkleinerung des gesamten Kopfhörers im unbenutzten Zustand gestattet. Die Muscheln sind dabei mit dem Bügel über eine pseudokugelige Aufhängung verbunden, was nur geringe Adaptionen an unterschiedliche Kopfformen zuläßt, durch den Aufbau des Bügeln als Nürnberger Schere ist es notwendig, die Leitung im Freien zu führen und dabei die Drähte durch Löcher in den Segmenten des Scherenmechanismus zu fixieren. Diese Konstruktion bietet, wie eingangs erwähnt, keinen überragenden Tragkomfort, stellt aber bei einfachem Aufbau eine passable Lösung, wenn auch nicht bei starker Kompaktierung im zusammengelegten Zustand dar.There are a large number of headband hanger, for example in AT 370 581 B. Headphone hanger disclosed, which is built like a pair of Nuremberg scissors and so allows a considerable reduction in the size of the headphones when not in use. The shells are connected to the bracket via a pseudo-spherical suspension, which allows only minor adaptations to different head shapes, through the To build up the iron as Nuremberg scissors, it is necessary to run the cable outdoors while closing the wires through holes in the segments of the scissor mechanism fix. As mentioned at the beginning, this construction does not offer outstanding comfort, but provides a passable solution with a simple structure, if not with a strong one Compacting in the folded state.

Aus der AT 370 275 B ist ein Kopfhörerbügel bekannt, der "im Kreis" teleskopierbar ist und so an unterschiedliche Kopfgrößen angepaßt werden kann. Über die Aufhängung der Muscheln ist nichts ausgeführt, desgleichen nichts über eine mögliche Kompaktierung des Kopfhörers im unbenutzten Zustand, es betrifft diese Druckschrift ausschließlich die Anpassung des Bügels an unterschiedliche Kopfgrößen.From AT 370 275 B a headphone bracket is known which is telescopic "in a circle" and can be adapted to different head sizes. About the suspension of the Nothing is done about mussels, nor is there anything about a possible compacting of the Headphones in unused condition, this document only concerns the adaptation the bracket to different head sizes.

) Aus der AT 338 350 B ist ein Kopfhörer bekannt, der mit einem elastischen Kopfband im Bügelbereich versehen ist, wodurch die Anpassungen an unterschiedliche Kopfgrößen erreicht wird, ohne dass der Kopfhörerbügel selbst einer Veränderung bedarf. Die Montage der Muscheln am Bügel wird nicht erwähnt, die Zeichnung ist diesbezüglich rein schematisch. Es betrifft diese Druckschrift somit weder die Anpassung des Kopfhörers an unterschiedliche Kopfformen noch die Kompaktierung des Kopfhörers im unbenutzten Zustand. Das gleiche gilt für die Kopfhörer gemäß der AT 326 743 B, die AT 313 392 B.) Headphones are known from AT 338 350 B, which have an elastic headband in the The temple area is provided, whereby the adaptations to different head sizes are achieved without changing the headphone hanger itself. The assembly the shells on the temple are not mentioned, the drawing is purely schematic in this regard. This publication therefore does not concern the adaptation of the headphones to different headphones Head shapes still compacting the headphones when not in use. The same applies to headphones according to AT 326 743 B, AT 313 392 B.

Kopfhörer, die sich mit der Anpassung der Stellung und Lage der Muscheln an die unterschiedlichen Kopfformen der Benutzer befassen, sind beispielsweise aus der AT 368 823 B bekannt. Dabei ist jede Muschel auf einem elastischem Band befestigt, das als Sehne im Kopfhörerbügel gespannt ist und erlaubt so durch Verschiebung entlang des Bandes eine Größenanpassung, und durch Schrägstellung der Muschel am Anlenkpunkt die Anpassung an die Kopfform. Durch die schräge Lage der Muschel am gespannten Band werden in die Muschel Kräfte eingeleitet, die zu einem Kippmoment der Muschel am Kopf führen und so trotz guter geometrischer Anpassung der Muschel nur geringen Komfort bieten.Headphones that deal with the adjustment of the position and location of the shells to the different Head shapes of the users deal, for example, from AT 368 823 B. known. Each shell is attached to an elastic band that acts as a tendon in the Headphone clamp is tensioned and thus allows one by moving along the band Size adjustment, and the inclination of the shell at the point of articulation to the head shape. Due to the inclined position of the shell on the tensioned belt are in the Shell forces are introduced that cause the shell to tilt and so on offer little comfort despite good geometric adaptation of the shell.

Aus der AT 297 111 B ist ein mehrteiliger Kopfhörerbügel mit Gelenken, die die einzelnen Teile verbinden, bekannt, der auf diese Weise eine bessere Adaptierung an die Kopfform ermöglichen soll, aber explizit nicht als zusammenlegbarer Kopfhörer gedacht ist.From AT 297 111 B is a multi-part headband with joints that the individual Connect parts, known, which in this way better adaptation to the head shape should enable, but is not explicitly intended as collapsible headphones.

Ebenfalls eine Adaption an unterschiedliche Kopfgrößen und Kopfformen ist aus der AT 217 105 B bekannt, wobei der federnde Bügel an seinen beiden Enden gerade verlaufende Abschnitte aufweist, an denen die Muscheln verschiebbar angeordnet sind. Über die weitere Beweglichkeit der Muscheln bezüglich des Bügels ist nichts ausgesagt.An adaptation to different head sizes and head shapes is also from the AT 217 105 B known, the resilient bracket running straight at both ends Has sections on which the shells are slidably arranged. About the no further movement of the shells with respect to the temple is indicated.

Aus der AT 321 388 B ist ein Kopfhörer bekannt, bei dem die Muscheln bezüglich des Bügels um Achsen, die auf die durch den Bügel gebildete Ebene normal stehen, verschwenkbar sind und sich so an die Schrägstellung der Ohren bzw. Auflageflächen der Muscheln von der breitesten Stelle des Kopfes zum sich verjüngenden Kinn angepaßt werden können, wobei noch federnde Elemente vorgesehen sind, durch die der Tragekomfort erhöht wird. Eine Anpassung an den sich nach vorne im allgemeinen verjüngenden Kopf ist ebensowenig vorgesehen wie eine Zusammenlegung im unbenutzten Zustand.From AT 321 388 B a headphone is known in which the shells with respect to the Bracket pivotable about axes that are normal to the plane formed by the bracket are and so the oblique ears or contact surfaces of the Shells can be adjusted from the widest part of the head to the tapered chin can, whereby still resilient elements are provided, through which the wearing comfort is increased. An adaptation to the generally tapering head is no more intended than a merger in the unused state.

Schließlich ist aus der AT 276 516 B ein zusammenlegbarer Kopfhörer bekannt, bei dem der Bügel aus zumindest drei Teilen besteht, die um Achsen, die normal zur Bügelfläche verlaufen, zueinander parallel geschwenkt werden können, wobei entweder die Muscheln so ausgebildet sind, dass sie nicht breiter sind als der Bügel oder aber die Muscheln um Achsen, die parallel zu den Randabschnitten des Bügels verlaufen, drehbar sind und so in diese Ebene geschwenkt werden können.Finally, a collapsible headphone is known from AT 276 516 B. The bracket consists of at least three parts, which are about axes that are normal to the ironing surface run, can be pivoted parallel to each other, either the shells are designed so that they are not wider than the temple or the shells around Axes that run parallel to the edge sections of the bracket, are rotatable and so in this level can be pivoted.

Weiters sind noch Kopfhörer bekannt, bei denen jede Muschel um eine Achse, die bei bestimmungsgemäßem Gebrauch der Kopfhörer und normal gehaltenem Kopf etwa horizontal verläuft, schwenkbar sind und diese Achsen von einem ebenfalls waagrecht liegenden Bogen gehalten werden, der in seinem Scheitelbereich um eine im wesentlichen vertikale Achse, die am Kopfhörerbügel montiert ist und zumindest im wesentlichen eine Verlängerung des Endbereichs des Kopfhörers bildet, verdrehbar ist. Diese sogenannte kardanische Aufhängung ermöglicht einen sehr hohen Tragekomfort, benötigt aber extrem viel Platz und widersetzt sich jeder Verringerung des Kopfhörervolumens im abgenommenen Zustand.Furthermore, headphones are known, in which each shell around an axis, the intended Use the headphones and normal head approximately horizontally runs, are pivotable and these axes from a horizontal as well Arch held in its apex by a substantially vertical Axle that is mounted on the headband and at least essentially an extension the end portion of the headphones is rotatable. This so-called gimbal Suspension allows a very high level of comfort, but requires an extremely large amount of space and opposes any reduction in headphone volume when removed.

Es ist Ziel der Erfindung, einen Kopfhörer zu schaffen, bei dem der Tragekomfort hoch ist und dessen Aufhängung dennoch wenig Platz benötigt und auch einer Kompaktierung des Kopfhörers im abgenommenen Zustand nicht im Wege steht. Gleichermaßen betrifft die Erfindung die Kompaktierung eines Kopfhörers im abgenommenen Zustand, die insbesondere auch den Tragekomfort keinesfalls stören, sondern wenn möglich, noch bessern soll.The aim of the invention is to provide headphones with which the wearing comfort is high and its suspension still requires little space and also a compacting of the Headphones when detached is not in the way. The same applies to Invention the compacting of a headphone in the detached state, in particular in no way disturb the wearing comfort, but should improve it if possible.

Erfindungsgemäß werden diese Ziele dadurch erreicht, dass jede Muschel des Kopfhörers mit dem Bügel über mindestens zwei Achsen gelenkig verbunden ist, wobei die beiden Drehachsen einander schneiden und der Schnittpunkt auf der Zentralachse der Muschel liegt.According to the invention, these goals are achieved in that each shell of the headphones is articulated to the bracket via at least two axes, the two The axes of rotation intersect and the point of intersection on the central axis of the shell lies.

Die Kopfhörermuscheln sind auch bei sehr eigenwillig ausgebildeten Kopfhörern im wesentlichen mit einem kreisrunden oder ovalen Querschnitt im Bereich der Kontaktfläche mit dem menschlichen Kopf versehen und weisen daher normal auf diese mittlere Kontaktfläche eine Zentralachse genannte Achse auf, die in vielen Fällen auch eine Symmetrieachse zumindest für die wesentlichsten Elemente der Muschel darstellt. Bei besonders außergewöhnlich gestalteten Querschnitten und Kontaktflächen des Kopfhörers kann der Schwerpunkt dieser Kontaktfläche als Fußpunkt oder Durchstoßpunkt der Zentralachse der Kontaktfläche angesehen werden. The headphone cups are also essential in the case of very idiosyncratically trained headphones with a circular or oval cross-section in the area of the contact surface provided with the human head and therefore normally point to this middle contact area an axis called a central axis, which in many cases also has an axis of symmetry represents at least for the most essential elements of the shell. At particularly extraordinary designed cross sections and contact areas of the headphones Center of gravity of this contact surface as the base point or penetration point of the central axis of the Contact area can be viewed.

In einer Ausgestaltung treffen die beiden Schwenkachsen etwa im Bereich des Durchstoßpunktes der Zentralachse durch die mittlere Auflagefläche des Kopfhörers auf die Zentralachse.In one embodiment, the two pivot axes meet approximately in the area of the penetration point the central axis through the central contact surface of the headphones on the central axis.

In einer weiteren Ausgestaltung spannen die beiden Drehachsen einen Winkel von 5° bis 75°, bevorzugt von 10° bis 20°, besonders bevorzugt von etwa 15°, zueinander auf.In a further embodiment, the two axes of rotation span an angle of 5 ° to 75 °, preferably from 10 ° to 20 °, particularly preferably from about 15 ° to each other.

Diese Aufgaben werden erfindungsgemäß dadurch gelöst, dass bei Zugrundelegung eines kartesischen Raumsystems, dessen Z-Ebene die Symmetrieebene des Kopfhörers darstellt, dessen Y-Ebene, die darauf normal stehende und durch die Mitte des Bügels gehende Ebene ist und dessen X-Ebene eine auf beide definierten Ebenen orthogonal stehende Ebene in beliebiger Höhe ist, zwischen dem Kopfhörerbügel und der gegebenenfalls gelenkigen Aufhängung jeder Muschel eine Drehachse vorgesehen ist, die mit jeder der drei Ebenen einen Winkel von zumindest 10°, bevorzugt von zumindest 15° einschließt. Durch diese Maßnahme erreicht man auf überraschende Weise, dass es unabhängig von der weiteren Aufhängung der Muscheln stets möglich ist, die Muscheln bezüglich der Ebene des Bügels, der Y-Ebene, so zu verdrehen, dass die Muscheln mit ihren Hauptabmessungen etwa parallel und im wesentlichen in diese Ebene zu liegen kommen, wodurch eine besonders kompakte Zusammenlegung der nicht benutzten Kopfhörer möglich wird.According to the invention, these objects are achieved in that, on the basis of a Cartesian spatial system, the Z-plane of which represents the headphones' plane of symmetry, its Y-plane, the plane that is normal to it and goes through the middle of the temple and whose X-plane is a plane orthogonal to both defined planes in is of any height between the headband and the possibly articulated Suspension of each shell has an axis of rotation provided with each of the three levels encloses an angle of at least 10 °, preferably of at least 15 °. Through this Measure is achieved in a surprising way that it is independent of the other Suspension of the shells is always possible, the shells with respect to the level of the temple, the Y-plane, so that the shells with their main dimensions are about parallel and essentially come to lie in this plane, which makes a special compact combination of the unused headphones is possible.

In einer bevorzugten Ausgestaltung schließt die Drehachse mit zumindest zwei der drei Ebenen einen Winkel von zumindest 20°, besonders bevorzugt von 25° ein. Damit erreicht man eine besonders kompakte Ausbildung des die Drehachse körperlich darstellenden Gelenks.In a preferred embodiment, the axis of rotation closes with at least two of the three Planes an angle of at least 20 °, particularly preferably of 25 °. So achieved a particularly compact design of the joint physically representing the axis of rotation.

In einer Weiterbildung der Erfindung ist vorgesehen, dass die beiden Drehachsen der beiden Muscheln durch Drehung um 180° um die Schnittgerade der Z-Ebene und der Y-Ebene (Z-Achse) zur Deckung gebracht werden können. Dadurch werden die Muscheln mit ihren Auflageflächen zueinander gerichtet positioniert und der zusammengelegte Kopfhörer wird besonders kompakt.In a development of the invention it is provided that the two axes of rotation of the two Shells by rotating 180 ° around the intersection line of the Z plane and the Y plane (Z axis) can be brought to congruence. This will make the shells positioned with their contact surfaces facing each other and the collapsed Headphones become particularly compact.

Die Erfindung wird im folgenden an Hand der Zeichnung näher erläutert. Dabei zeigt

    • Die Fig. 1 zeigt einen in seiner Gesamtheit mit 1 bezeichneten erfindungsgemäß ausgebildeten Kopfhörer. Der Kopfhörer besteht im wesentlichen aus einem Bügel 2 und zwei nicht weiter unterschiedenen Muscheln 3.

The headphones consist essentially of a bracket 2 and two no further differentiated shells 3. The transition between the bracket 2 and the Shells 3 can now, as mentioned at the beginning, take place in a variety of ways, illustrated and in A particularly preferred embodiment according to the invention is described below.

    Zuerst soll aber an Hand der perspektivischen Ansicht der Fig. 1 das Bezugssystem, auf das die Lage der verschiedenen Drehachsen bezogen wird, näher erläutert werden: Die Symmetrieebene des Kopfhörers wird als Z-Ebene bezeichnet und ist auch als solche in der Zeichnung eingetragen. Normal zur Z-Ebene und durch die Mitte des Bügels 2 verlaufend, ist die Y-Ebene definiert, wie in Fig. 2 genauer eingezeichnet. Die X-Ebene, die auf die beiden genannten Ebenen normal steht, kann in beliebiger Höhe angenommen werden, sie wird nur zur Definition von Winkeln zwischen sich und den Drehachsen benötigt. In Fig. 1 sind zwar diese drei Ebenen eingetragen, nicht aber die Achsen des daraus resultierenden orthogonalen Koordinatensystems, weil die Achsen für die vorliegende Erfindung wesentlich weniger Bedeutung aufweisen als die Ebenen.First, however, the reference system should be based on the perspective view of FIG that the position of the different axes of rotation is related, are explained in more detail: The The plane of symmetry of the headphones is referred to as the Z plane and is also as such in the Drawing entered. Normal to the Z plane and running through the middle of the bracket 2, the Y plane is defined, as shown in more detail in FIG. 2. The X plane that is on the both levels mentioned is normal, they can be assumed in any amount is only required to define angles between itself and the axes of rotation. In Fig. 1 these three levels are entered, but not the axes of the resulting one orthogonal coordinate system because the axes are essential to the present invention are less important than the levels.

    Die Bestimmung der Lage der Ebene Z ist eine problemlose Selbstverständlichkeit, die Lage der Ebene Y hingegen, wie aus Fig. 2 ersichtlich, kann bei sehr eigenwillig gestalteten Kopfhörern zu Definitionsproblemen führen, da es durchaus auch Kopfhörer gibt, deren Bügel nicht auf so eindeutige Weise eine Mittelebene definieren, wie dies beim dargestellten Kopfhörer der Fall ist. Da aber alle Kopfhörer, die einigermaßen auf Tragkomfort Wert legen, die Mitte 4 des Scheitels des Bügels und die Mitte (Schwerpunkt) der Muscheln 3 des Kopfhörers (im außerordentlichen Gestaltungsfall der Schwerpunkt der als eben angenommenen Kontaktfläche der Muschel mit dem Kopf), in sehr engen Grenzen gleich anordnen, kann auch bei derart eigenwillig gestalteten Kopfhörern die Ebene Y mit engen Toleranzen gefunden und festgelegt werden.The determination of the position of the level Z is a matter of course that Position of the plane Y, however, as can be seen from FIG. 2, can be designed in a very idiosyncratic manner Headphones lead to definition problems, since there are also headphones whose Brackets do not define a central plane in such a clear way as in the depicted Headphones is the case. But since all headphones are reasonably comfortable Value the middle 4 of the vertex of the temple and the middle (center of gravity) of the shells 3 of the headphones (in the extraordinary design the focus of the as assumed surface of contact of the shell with the head), within very narrow limits Arrange the same way, even with headphones designed in such an idiosyncratic way, level Y can also be used narrow tolerances are found and determined.

    Wenn diese beiden Ebenen gefunden sind, so kann die X-Ebene in jeder beliebigen Höhe angenommen werden, ihre Richtung liegt bereits eindeutig fest. Im dargesellten Ausführungsbeispiel wurde die X-Ebene in den mittleren Bereich der Gelenkskonstruktion 6, d.i. die Gesamtheit der Konstruktion, die den Bügel 2 mit den Muscheln 3 verbindet, gelegt.When these two levels are found, the X level can be at any height assumed, their direction has already been clearly determined. In the illustrated embodiment the X-plane was in the middle area of the joint construction 6, i.e. the whole of the structure that connects the bracket 2 with the shells 3, placed.

    Aus Fig. 1 und insbesondere aus Fig. 4 geht hervor, dass im gezeigten Ausführungsbeispiel die Muscheln 3 eine kreisförmige Ausbildung sowohl der Kontaktfläche 7 als auch der inneren Lautsprecherfläche 8 aufweisen. Dies ist nicht notwendig, bei sehr eigenwillig geformten Muscheln ist es zur Bestimmung der erfindungsgemäßen Relationen notwendig, entsprechende Äquivalenzgrößen heranzuziehen. Dazu eignet sich eine bestmögliche Annäherung der Kontaktfläche 7 an eine Ebene und der Ersatz der Kreismitte 9 der Fig. 4 durch den Schwerpunkt der ebenen Ersatzkontaktfläche. So ist es möglich, auch bei sehr eigenwillig gestalteten Muscheln eine Zentralachse 10 zu definieren.From Fig. 1 and in particular from Fig. 4 it appears that in the embodiment shown the shells 3 have a circular configuration of both the contact surface 7 and the have inner speaker surface 8. This is not necessary in the case of very idiosyncratic shaped mussels it is necessary to determine the relations according to the invention, to use corresponding equivalence quantities. The best possible approximation is suitable for this the contact surface 7 to a plane and the replacement of the circle center 9 of FIG. 4 through the center of gravity of the flat replacement contact surface. So it is possible, even with very idiosyncratically designed shells to define a central axis 10.

    Erfindungsgemäß werden nun die zum Erreichen eines hervorragenden Tragkomforts vorgesehen Drehachsen K1 und K2 folgendermaßen bezüglich der Bezugsebenen angeordnet: Die Muschel 3 ist um eine Drehachse K1 eines Armes 12 drehbar. Der Arm 12 wiederum ist um eine Drehachse K2 des Bügels 2 drehbar. Die Drehachse K2 kann, wie im gezeigten Beispiel, an einem Tragarm 15 des Bügels 2 angeordnet sein, der, für die Zwecke der Anpassung an die Kopfform des Benutzers als fest mit dem Bügel verbunden anzusehen ist, wenn er auch, wie unten angeführt, bezüglich des Bügels ebenfalls schwenkbar sein kann.According to the invention, those are now provided to achieve excellent wearing comfort Axes of rotation K1 and K2 are arranged as follows with respect to the reference planes: The shell 3 is rotatable about an axis of rotation K1 of an arm 12. The arm 12 in turn is rotatable about an axis of rotation K2 of the bracket 2. The axis of rotation K2 can, as shown in FIG Example, be arranged on a support arm 15 of the bracket 2, which, for the purposes of adaptation the head shape of the user is to be regarded as firmly connected to the bracket, although, as mentioned below, it can also be pivotable with respect to the bracket.

    Die beiden Drehachsen K1, K2 schneiden einander, wie aus dem Zusammenhalt der Fig. 3 und 4 hervorgeht, auf der Zentralachse 10 der Muschel 3, bevorzugt im Gebiet der Auflagefläche 7. Durch diese Maßnahme wird mit geringstem Platzbedarf sichergestellt, dass die durch die federnde Elastizität des Bügels 2 bewirkte Anlage der Muschel 3 am Kopf des Benutzers unabhängig von dessen Kopfform praktisch momentenfrei erfolgt und so den höchsten Komfort bietet. The two axes of rotation K1, K2 intersect, as from the cohesion of FIG. 3 and 4 emerges on the central axis 10 of the shell 3, preferably in the area of the support surface 7. This measure ensures that the caused by the resilient elasticity of the bracket 2 system of the shell 3 on the head of Regardless of the shape of the head, the user is practically torque-free and thus the offers maximum comfort.

    Es ist auch möglich, von dem in Fig. 3 dargestellten Idealschnittpunkt abzuweichen, sei es entlang der Zentralachse 10 oder durch Verlagern des Schnittpunktes von der Zentralachse 10 weg, es führen aber all diese Abweichungen, sofern sie über sehr geringe Abstände hinausgehen, zu einer merklichen Verschlechterung des Tragkomforts. Nur bei extrem weicher und dicker Auflage 13 der Muscheln 3 ist es möglich, den Schnittpunkt auf der Zentralachse etwas von der Kontaktebene 7 weg in Richtung des Zentrums des Kopfhörers, zur Lautsprecherebene 8 (Fig. 1) zu verlegen, um der Kompression und damit Deformation der Auflage 13 Rechnung zu tragen. Damit wird bei der Benutzung des Kopfhörers der Schnittpunkt wiederum möglichst genau in die reale Kontaktebene gebracht.It is also possible to deviate from the ideal intersection shown in FIG. 3, be it along the central axis 10 or by moving the intersection from the central axis 10 away, but all these deviations lead if they go beyond very short distances, to a noticeable deterioration in comfort. Only with extremely soft and thicker edition 13 of the shells 3, it is possible to find the intersection on the central axis something away from the contact plane 7 towards the center of the headphones Loudspeaker level 8 (Fig. 1) to move the compression and thus the deformation of the Edition 13 to be taken into account. So that when using the headphones Intersection, in turn, brought as precisely as possible into the real contact level.

    Es ist auch möglich, die beiden Drehachsen K1, K2 nicht zum Schnitt zu bringen, sondern knapp aneinander vorbeilaufen zu lassen, dies ist aber ebenso wie die oben genannte Verlagerung des Schnittpunktes mit einer Verringerung des Tragkomforts verbunden und daher als Verschlechterung anzusehen. Aus diesem Grund ist es Wünschenswert, die oben genannte Konstellation des Schnittpunktes im Rahmen der herstellungsbedingten Toleranzen anzustreben.It is also possible not to bring the two axes of rotation K1, K2 to the intersection, but rather letting it run close to each other, but this is just like the relocation mentioned above the intersection associated with a reduction in comfort and therefore to be regarded as deterioration. For this reason, it is desirable to do the above mentioned constellation of the intersection within the scope of the manufacturing tolerances desirable.

    Erfindungsgemäß ist zur Kompaktierung des Kopfhörers auf kleinstem Raum, wenn er nicht getragen wird, sein Zusammenklappen vorgesehen. Dazu ist eine Raumachse R, um die das Zusammenklappen erfolgt, vorgesehen (Fig. 2 und 3), die mit jeder der drei definierten Bezugsebenen einen Winkel von zumindest 10°, bevorzugt von zumindest 15° einschließt. Unabhängig von der Aufhängung der Muscheln am Bügel, somit auch bei Muschelaufhängungen, die nicht der oben definierten Erfindung entsprechen, ist es dadurch möglich, die Kopfhörer mit ihren Kontaktebenen 7 im wesentlichen parallel zur Y-Ebene (Zeichenebene der Fig. 3) zu drehen und dabei, je nach Größe des Bügels 2 und der Muscheln 3, diese nebeneinander oder mit praktisch fluchtender Zentralachse 10 "aufeinander" anzuordnen und so zu einer besonders kompakten Form des nicht getragenen Kopfhörers zu kommen.According to the invention for compacting the headphones in the smallest of spaces when he is not worn, its folding is provided. For this there is a spatial axis R, um the folding takes place, provided (Fig. 2 and 3), which are defined with each of the three Reference planes includes an angle of at least 10 °, preferably of at least 15 °. Regardless of the suspension of the shells on the bracket, thus also with shell suspensions, which do not correspond to the invention defined above, it is possible, the headphones with their contact planes 7 substantially parallel to the Y plane (Drawing plane of Fig. 3) to rotate and, depending on the size of the bracket 2 and the shells 3, these side by side or with practically aligned central axis 10 "on top of each other" to arrange and so to a particularly compact shape of the headphones not worn get.

    Die Fig. 5 zeigt in drei Ansichten einen auf die erfindungsgemäße Weise zusammengelegten Kopfhörer 1: Am Bügel 2 sind über einfache, elastische Arme 14 Muscheln 3 befestigt. Zwischen dem Bügel und jedem der Arme ist eine Drehachse R vorgesehen, die die obigen Bedingungen bezüglich ihrer Lage im Raum erfüllt. Die beiden Drehachsen sind nicht symmetrisch bezüglich der Z-Ebene (Fig. 1) angeordnet, sondern zentralsymmetrisch bezüglich der Z-Achse, d.h., eine der beiden Drehachsen R ist "vor", die andere "hinter" der Y-Ebene am Bügel 2 vorgesehen. Dadurch werden die beiden Muschel 3 mit ihren Kontaktflächen 7 zueinander geklappt und der Raum unter dem Bügel 2 wird bestmöglich genützt. Es ist aus der Fig. 5 leicht ersichtlich, dass durch entsprechende Wahl der Länge des Bügels 2 und der Arme 14 die Position der Muscheln zueinander im zusammengeklappten Zustand beeinflußt werden kann.FIG. 5 shows in three views one folded in the manner according to the invention Headphones 1: 14 shells 3 are attached to the bracket 2 by simple, elastic arms. Between the bracket and each of the arms an axis of rotation R is provided, which the above Conditions regarding their location in the room are met. The two axes of rotation are not arranged symmetrically with respect to the Z plane (Fig. 1), but centrally symmetrical with respect the Z axis, i.e. one of the two axes of rotation R is "in front", the other "behind" the Y level provided on bracket 2. As a result, the two shells 3 with their contact surfaces 7 folded to each other and the space under the bracket 2 is used in the best possible way. It is easy to see from FIG. 5 that by appropriate choice of the length of the Temple 2 and the arms 14 the position of the shells to each other in the folded Condition can be influenced.

    Eine Variante ist in Fig. 6 dargestellt: Der Kopfhörer 1 weist nicht nur die Drehachsen R auf, sondern auch die Drehachsen K1 und K2, und durch die getroffene Wahl der Abmessungen kommen die Muscheln 3 im zusammengeklappten Zustand voll zur Deckung, die höchstmögliche Kompaktierung ist erreicht. Diese Kompaktierung ist, wie der Vergleich mit der Fig. 5 zeigt, nur von der Lage und Ausrichtung der Drehachse R abhängig, die Drehachsen K1 und K2 tragen dazu nichts bei.A variant is shown in FIG. 6: the headphones 1 not only have the axes of rotation R on, but also the axes of rotation K1 and K2, and by the choice of dimensions the mussels 3 come fully to cover when folded, which highest possible compaction has been achieved. This compacting is like the comparison 5 shows, depending only on the position and orientation of the axis of rotation R, which Axes of rotation K1 and K2 do not contribute to this.
