Description

Es gibt Kopfhörer für Fernsprechbetrieb und Radioempfang, bei welchen innerhalb des Bügels ein Band aus nachgiebigem Stoff an drei oder mehr Punkten so befestigt ist, daß das Band den Kopf des Hörers umgreift und sich seiner Form anpaßt. Diese Anordnung hat eine Verwirrung des Haares zur Folge, wenn der Hörer am Kopf zurechtgerückt wird, damit die Muscheln in die richtige Stellung zum Ohr gelangen.There are headphones for telephone operation and radio reception, in which within the A strap of flexible fabric is attached to three or more points in such a way that the tape encompasses the head of the listener and adapts to its shape. This arrangement results in hair confusion when the headphone is adjusted so that the clams are in the correct position Position to the ear.

Dieser Nachteil wird nach der Erfindung dadurch vermieden, daß das den Kopf umspannende Band unelastisch ist und an einem Ende unten mit einer Federtrommel verbunden ist, mittels welcher das Bandende verkürzt oder verlängert werden kann, so daß das um den Kopf gespannte Band ruhig liegenbleibt, während der Bügel gespreizt wird.This disadvantage is avoided according to the invention in that the head spanning Band is inelastic and is connected at one end to a spring drum, by means of which the end of the band is shortened or can be lengthened so that the band stretched around the head rests quietly while the temple is spread apart will.

Das Anlegen der Ohrmuschel kann von Hand oder mechanisch geschehen. Der Bügel besteht im letzten Falle aus zwei gelenkig miteinander verbundenen Teilen, von denen der der verstellbaren Ohrmuschel gegenüberliegende Teil als Schiene ausgebildet und an der anderen Ohrmuschel befestigt ist. Der zweite Teil ist in dieser Schiene als Schieber geführt und an dem anderen Bügelteil angelenkt. Die Schiene und der Schieber sind je mit einem Handgriff versehen, die beim Zusammendrücken die Hörmuschel unter Spannung einer Feder vom Kopf abheben, die beim Anlegen der Muschel durch Entspannen den Bügelteil mit der Ohrmuschel selbsttätig in die Gebrauchslage bringt. Die bewegliche Muschel kann dabei einfach als Widerlager ausgebildet sein.The auricle can be put on by hand or mechanically. The coat hanger consists in the latter case of two articulated parts, of which the the adjustable auricle opposite part designed as a rail and on the other auricle is attached. The second part is in this rail as a slider guided and hinged to the other bracket part. The rail and the slider are each provided with a handle that, when pressed together, lift the earpiece from the head under tension under the tension of a spring Put on the shell by relaxing the bracket part with the auricle automatically in brings the position of use. The moving shell can simply act as an abutment be trained.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Der Kopfhörer besteht aus zwei Armen 11, 12, die bei 13 miteinander gelenkig verbunden sind. Der Arm 11 trägt am äußeren Ende einen Arm 23 und eine zylindrische Trommel 24 mit einer innenliegenden Spiralfeder 25. An der Oberfläche der Trommel ist ein Band 26 vorzugsweise aus einem leicht biegsamen Stoff, z. B. Leder, befestigt. Das andere Ende des Bandes 26 ist am unteren Ende des Armes 12 befestigt, so daß das Band für gewöhnlich gespannt ist. Am Ende des Armes 12 ist ein Träger 28 für einen Mikrophonhörer 29 angeordnet, der mit einer Ohrmuschel 30 versehen ist. Der Arm 23 trägt ein gelenkig daran befestigtes Kissen 27, das sich selbst an das Ohr oder gegen die Seite des Kopfes des Benutzers ohne die geringste Unbequemlichkeit einstellt. Statt des Kissens 27 kann auch eine Hörmuschel benutzt werden, wenn man mit beiden Ohren hören will.The headphone consists of two arms 11, 12, which are articulated to one another at 13. The arm 11 carries at the outer end an arm 23 and a cylindrical drum 24 with an internal spiral spring 25. On the surface of the drum, a belt 26 is preferably made of a slightly pliable one Fabric, e.g. B. leather attached. The other end of the band 26 is at the lower end of the arm 12 attached so that the tape is usually tensioned. At the end of the arm 12 is a Support 28 is arranged for a microphone receiver 29 which is provided with an auricle 30 is. The arm 23 carries an articulated pillow 27 which attaches itself to the ear or against the side of the head of the user without the slightest discomfort. Instead of the pillow 27 can an earpiece can also be used if one wants to hear with both ears.

Der Arm 12 dient als Schiene zur Führung eines Schiebers 17. Der Arm 11 besitzt jenseits des Drehpunktes 13 einen mit einemThe arm 12 serves as a rail for guiding a slide 17. The arm 11 has beyond of the pivot point 13 one with a

Arm 14 provided with slot 15. In slot 15 a pin 16 of the slide 17 is slidably arranged so that during the upward and downward movement of the slide 17 of the arm 11 from the position shown in the with Dotted lines indicated position can be moved. The following is used for this mechanical device:

On the slide 17 is a handle 18 on Arm 12 is attached to a handle 19. Both Handles are provided with pins 20, 21 for holding a coil spring 22, which the usually holds both handles 18, 19 apart and so the rod 17 upwards

¹ S moves, the arm 11 then pressing against the other side of the head. In order to place the body on the head, it is brought into the dot-dash position as usual, the handles 18, 19 being pressed against one another. In this position of the parts, the earpiece 30 is then first brought into the correct listening position. In this preliminary position of the listener, the user can determine whether the conversation is intended for him or for someone else. If this is not the case, the user can put the earpiece down. Otherwise, he lets go of the handles so that they spread under the action of the spring 22, whereby the arm 11 moves into the position shown in full lines. The band 26 then also lies over the head without the slightest disturbance, with the ear cushion then. 27 clings to the ear by itself. The user then has his hand free. If necessary, the user can help a little.

In the case of stand apparatus for which the invention is particularly intended, a flexible tube 33, which leads from the microphone of the stand to the speaking horn through a flexible member 31 can be brought in front of the user's mouth at the same time which the listener is placed on the ear. When using this arrangement remain Both hands free as soon as the receiver is on. The writing desk in front of the user is free, so that he can read and write.
