Abstract

The stereo headphones give the listener the impression of 'front sound' by incorporating a third transducer in the bracket of the headphones. Two standard loudspeakers are located over the listener's ears. The third transducer (K) induces sound waves in the bones of the head. The left and right signal are added and passed to the third transducer. This sum signal component can be varied. The advantage lies in making the reproduction as 'natural' as possible by avoiding location errors.

Description

Beschreibung der P a t e n t a n s p r ü c h eDescription of the P a t e n t a n s p r ü c h e

Titel: Ein Stereokopfhörer zur Übertragung der Vorne-Ortung Anwendungsgebiet: Die Erfindung betrifft eine Anordnung, die die Wiedergabe kunstkopfstereophoner Aufzeichnungen mit einer Kopfhöreranordnung gestattet, die den großen Nachteil der fehlenden Vorneortung bei der Kopfhörerwiedergabe 5 tereop honer Signale besonders bei Titunstkopfstereophonie vermeidet.Title: A stereo headset for transmitting the front-end location. The invention relates to an arrangement for reproducing artificial head stereophones Recording with a headphone arrangement is permitted, which has the major disadvantage of Missing pre-localization when listening to headphones 5 tereop honer signals in particular avoids with Titunstkopfstereophonie.

Zweck: Beim natürlichen Hören treffen die Schallwellen nicht nur über die Gehörgänge auf die Schnecken der Ohren. Da der Kopf vom Schall umspült wird, gelangt ferner über die Schädelknochen und die Schädelhohlräume Schall mit sehr kurzen Laufzeitdifferenzen als Knochenschall auf beide Schnecken. Bei der Kopfhörerwiedergabe fehlt dieser Knochenschall. Daher treten Fehlortungen auf. Diese sollen durch eine Kopfhöreranordnung für stereophone Übertragungen speziell auch bei Kunstkopfstereophonie vermieden werden.Purpose: In natural hearing, the sound waves don't just hit over the ear canals on the snails of the ears. Since the head is washed around by the sound, Furthermore, sound passes through the cranial bones and the cranial cavities with a great deal of sound short runtime differences as bone conduction on both snails. When listening to headphones this bone conduction is missing. Therefore mislocations occur. These should be through a Headphone arrangement for stereophonic transmissions, especially with artificial head stereophony be avoided.

Stand der Technik: In der Kunstkopfstereophonie geht man von der Annahse aus, daß die gesamte akustische Information über ;lie Außenohren, die Gehörgänge, die Tronmelfelle in die Sinuesorgane, Cochleen, gelangen. Trotz aufwendigster Technik geliagt es er Stereophonie, sogar der Kuns tkop fs tereoplionie , nicht, Febllokalisationen, wie fehlende Vorneortung, zu vermeiden.State of the art: In artificial head stereophony one proceeds from the assumption that the entire acoustic information is transmitted through the outer ears, the auditory canals, the eardrums get into the sinus organs, cochleen. Despite the most complex technology if he likes stereophony, even the art head fs stereoplionie, not feble localizations, such as missing pre-location, to avoid.

Kritik am Stand der Technik: Bei der ICunstkopfstereophonie wird die Tatsache :.berset n, daß der Kopf des Zuhöreres beim normalen Hören vn den Schall wellen umflutet wird. Er nimmt an der gegenüber den Trommelfellen großen Oberfläche'trotz ungünstiger Anpassung, Schall auf. Dieser gelangt als Körperschall sehr schnell auf die Cochlcen. Dieser Körperschall fehlt bei der Kopfhörerwiedergabe kunstkopf-stereophoner Aufnahmen. Es kommt zu den bekannten Fehlortungen, wie Im-Kopf-Lokalisation und fehlende Vorwärtsortung.Criticism of the state of the art: With the ICunstkopfstereophonie the Fact: translates into the fact that the listener's head in normal hearing is affected by sound waves is flooded. He takes on the large surface compared to the eardrums unfavorable adjustment, sound on. This arrives very quickly as structure-borne sound on the cochlea. This structure-borne sound is missing in the headphone reproduction of artificial head stereophonic Recordings. The well-known mislocations such as in-head localization and lack of forward tracking.

Aufgabe: Der Erfindung liegt die Aufgabe zugrunde, die Fehlortungen zu vermeiden und dem Schädel den fehlenden Kürperschall bei der Kopfhörerwiedergabe zu zuführen, Lösung: Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß im Bägel des Kopfhörers ein oder mehrere Knochenschallgeber angebracht werden, die die Signale beider Dhrkanäle bei der stereophonen Wiedergabe als Körperschall in den Schädel einspielen.Task: The invention is based on the task of the mislocations to avoid and the skull the missing body-borne noise when listening to headphones to feed, solution: This object is achieved according to the invention in that in the bracket One or more bone sound transducers are attached to the headphones to generate the signals Both Dhrkanal in the stereophonic reproduction as structure-borne sound in the skull import.

Wt-itre Ausgestaltung: Durch Zwischenschaltung geeigneter Abschwächer kann der Knochenschallanteil individuell an den einzelnen Zuhörer angepaßt werden.Wt-itre embodiment: By interposing suitable attenuators the bone conduction fraction can be individually adapted to the individual listener.

Beschreibung eines Ausführungsbeispiels: Ein Ausführungsbeispiel der Frfindung ist in der Zeichnung dargestellt. Das rechte und linke Ohrsignal Rleiner Runstkopfaufnahme gelangen in üblicher Weise auf die beiden llörer eines Kopfhörers, den der Zuhörer trägt. Im Bügel des Kopfhörers ist im einfachsten Fall in der Mitte ein atnochenschallgeber Kangebracht, der das von den beiden Kanälen gelieferte Summensignal nach Durchlaufen des Summenverstärkers mit Abschächer in den Schädel des Zuhörers mit geeigneter Phasenlage einspeist.Description of an exemplary embodiment: An exemplary embodiment of the The invention is shown in the drawing. The right and left ear signals Rleiner Runstkopfaufnahme get in the usual way on the two ears of a headphone, that the listener wears. In the simplest case, the headphone bracket is in the middle An atnone sounder K is attached, which the sum signal delivered by the two channels after passing through the sum amplifier with attenuator in the skull of the listener feeds in with a suitable phase position.

Erzielbare Vorteile: Die mit Hilfe der Erfindung erzielbaren Vorteile bestehen darin, daß durch den in den Schädel gespeisten Knochenschall über das Gehör die Information "Beschallung von außen" den Zuhörer zugeführt wird, die besonders für die Vorneortung notwendig ist.Achievable Advantages: The advantages that can be achieved with the aid of the invention consist in that through the hearing through the bone conduction fed into the skull the information "sound from outside" is fed to the listener, which is particularly important is necessary for prelocation.
