Abstract

The headphones has right and left housing associated with the user's ears with sound walls (10) in which dynamic sound transducers (12,13) are mounted that each contain a treble device (13) and a coaxial middle/bass device (12). The sound wall in each housing has a first section (14) with high damping that covers a region of more than 170 and less than 340 degrees of the middle/bass device with a gap for the treble and an essentially V-shaped area (15) with an opening angle less than 170 and greater than 20 degrees. A second high damping region (17) near the tip of the V-section exposes between 50 and 50 per cent of the treble decvice.

Description

Die Erfindung betrifft einenKopfhörer mit zwei, den Ohren eines Nutzers zugeordneten rechten und linken Gehäusen, die Schallwände aufweisen, in denen dynamische Schallwandler angeordnet sind, die jeweils einen Hochtöner und einen koaxial zu diesem angeordneten Mitten-/Tieftöner umfassen.The invention relates to a headset having two ears associated with a user Right and left enclosures that have baffles in which dynamic transducers are arranged, each arranged a tweeter and a coaxial with this Include mid / woofers.

Stereo-Kopfhörer weisen üblicherweise eine Anordnung der Schallwandler im Zentrum der Gehäuse des Kopfhörers auf. Diese herkömmliche Anordnung hat den Nachteil, daß von ihm erzeugte Schallereignisse von einem Nutzer als oben im Kopf lokalisiert mit einer gewissen Differenzierung in einer nach hinten gerichteten Hemisphäre wahrgenommen werden. Das heißt, Schallereignisse, die etwa eine vor einem Nutzer angeordnete Bühne wiedergeben sollen, werden bei Wiedergabe über einen herkömmlichen Stereo-Kopfhörer nicht vorne lokalisiert. Dies widerspricht dem normalen menschlichen Hörempfinden, weshalb Kopfhörer von großen Kreisen der Hörerschaft als unnatürlich abgelehnt werden.Stereo headphones usually have an arrangement of the sound transducer in the center the housing of the headphones on. This conventional arrangement has the disadvantage that Sound events generated by it are localized by a user as being at the top of the head perceived certain differentiation in a rearward hemisphere become. That is, sound events that are about a user-facing stage play when using a conventional stereo headphones not located in front. This contradicts normal human hearing, which is why headphones are rejected as unnatural by large circles of the audience.

Als Ursache für das Phänomen der Im-Kopf-Lokalisierung von Schallereignissen bei Wiedergabe über Kopfhörer ist verantwortlich, daß üblicherweise wahrgenommene kammfilterartige Effekte aufgrund Ohr- und Körperreflexionen bei der Schallrezeption über Kopfhörer vom Ohr nicht verarbeitet werden können, da sie diesem nicht zugeführt werden.As a cause for the phenomenon of in-head localization of sound events during playback About headphones is responsible that commonly perceived comb filter-like Effects due to ear and body reflections during sound reception via headphones Can not be processed by the ear, since they are not supplied to this.

Es ist bekannt, diesen Nachteil dadurch zu überwinden, daß die fehlenden Kammfiltereffekte dem dem Kopfhörer zugeführten Signal hinzugemischt werden. Dies erfordert einen hohen schaltungstechnischen Aufwand. Ein weiterer Nachteil dieser Vorgehensweise besteht darin, daß eine Anpassung an das individuelle Ohr des Nutzers vorgenommen werden muß, um auf diese Weise zu einer befriedigenden Vorne-Ortung per Kopfhörer zu gelangen.It is known to overcome this disadvantage in that the missing comb filter effects be added to the signal supplied to the headphone. This requires one high circuit complexity. Another disadvantage of this approach is in that an adaptation to the individual ear of the user are made must, in order to arrive in this way to a satisfactory front-localization by headphones.

Auf den Erfinder der vorliegenden Anmeldung geht ein völlig anders gearteter Vorschlag zur Erzeugung der Vorne-Ortbarkeit per Stereo-Kopfhörer zurück, der beispielsweise in der EP 0 484 354 B1 offenbart ist. Gemäß diesem Vorschlag werden die zur Vorne-Ortbarkeit benötigten kammfilterartigen Veränderungen bei vom Kopfhörer abgestrahlten Schall dadurch hervorgerufen, daß die Schallwandlersysteme in beiden Kopfhörergehäusen ausgehend von der herkömmlichen Anordnung zentral am Außenohrrelief in Blickrichtung nach vorn und unten um vorgegebene Beträge verschoben angeordnet sind. Durch diese relativ einfache Maßnahme wird die bislang Oben-im-Kopf-Lokalisation in ein im wesentlichen horizontal vorne ortbares Hörereignis umgewandelt.The inventor of the present application is a completely different kind proposal for generating the front-localization via stereo headphones back, for example, in EP 0 484 354 B1. According to this proposal, the to-be-traded needed comb filter-like changes emitted by the headphone Sound caused by the fact that the Schallwandlersysteme in both headphone housings starting from the conventional arrangement centrally on the outer ear relief in the direction of view are arranged shifted forward and down by predetermined amounts. Through this relatively simple measure is the so far top-in-the-head localization in a substantially converted horizontally forward locatable auditory event.

Nach diesem Prinzip arbeitende Kopfhörer zur Vorne-Lokalisation von Schallereignissen haben sich bewährt. Für Kopfhörer kleiner Bauform, beispielsweise für auf dem Ohr aufliegende Kopfhörer von Walkmen und dergleichen ist eine nach vorne und unten verschobene Anordnung der Schallwandler jedoch weniger gut realisierbar.Headphones working on this principle for the front-localization of sound events have proven themselves. For headphones of small design, for example, resting on the ear Headphones by Walkmen and the like is a moved forward and down Arrangement of the transducer but less well feasible.

Ebenfalls vom Erfinder der vorliegenden Anmeldung ist aus WO 95 14362 ein Mehrkanalkopfhörer mit gesteuerter Abstrahlcharakteristik bekannt, der zumindest einen Schallwandler enthält, dessen Abstrahlfläche in zwei Teilflächen unterteilt ist, die unterschiedliche akustische Widerstände haben und über eine Trennlinie aneinander angrenzen, wobei die akustisch schwächer bedämpfte Teilfläche vorwiegend unter dem Gehörgang eines Außenohrs des Kopfhörer-Benutzers angeordnet ist, während die andere Teilfläche mit größerer akustischer Bedämpfung vorwiegend über dem Gehörgang liegt. Durch diese Maßnahme wird anstelle der üblicherweise auftretenden Oben-Im-Kopf-Lokalisation ein im wesentlichen horizontal vorne geordnetes Hörereignis erzeugt.Also from the inventor of the present application is from WO 95 14362 a Multi-channel headphones with controlled radiation characteristic known, the at least one Sound transducer contains the emitting surface is divided into two sub-areas, the have different acoustic resistances and a dividing line together adjacent, wherein the acoustically weaker damped subarea predominantly below the Ear canal of an outer ear of the headset user is arranged while the other Subarea with greater acoustic attenuation is predominantly above the ear canal. By this measure, instead of the usually occurring Top-in-the-head localization a substantially horizontally front-ordered hearing event generated.

Ziel der vorliegenden Erfindung ist, eine Vorne-Lokalisierbarkeit mit einfachen Mitteln ohne Einsatz von Elektronik auch für Kleinkopfhörer zu realisieren.The aim of the present invention is a front-localizability with simple means without the use of electronics even for small headphones to realize.

Weiteres Ziel der Erfindung ist, einen Kopfhörer mit steuerbarer Lokalisierbarkeit eines Schallereignisses zu schaffen.Another object of the invention is a headphone with controllable localizability of a Create sound event.

Weiteres Ziel der Erfindung ist schließlich die Schaffung eines Surround-Kopfhörers mit Vorne-Lokalisierbarkeit der vorderen Kanäle und eines Mittenkanals sowie einer hiervon getrennten Lokalisierbarkeit von Surround-Kanälen.Another object of the invention is finally to provide a surround headphones with Front-localizability of the front channels and a central channel as well as one of them separate localizability of surround channels.

Um die vorstehend genannten Ziele zu erreichen, schafft die vorliegende Erfindung einen Kopfhörer mit den Merkmalen des Anspruchs 1. Dieser Kopfhörer erlaubt das Steuern der Lokalisierbarkeit von mit dem Kopfhörer wiedergebenen Schallereignissen durch kammfilterartige Einwirkungen auf den Frequenzgang des Wiedergabeschalls, erzeugt durch gezielte Abschattung des abgestrahlten Schalls. Hierbei kann es sich um einen Kopfhörer kleiner und kleinster Bauform handeln, da die koaxialen Schallwandler im Kopfhörer in herkömmlicher Weise angeordnet sind und die Steuerung der Lokalisierbarkeit des Schal-lereignisses dadurch realisiert wird, daß Bereiche des Tief-Mitteltöners sowie des Hochtöners in gezielter Weise abgedeckt bzw. gedämpft werden.To achieve the above objects, the present invention provides a Headphone with the features of claim 1. This headphone allows controlling the Locatability of sound events reproduced with the headphone by comb filter-like Effects on the frequency response of the reproduction sound, generated by targeted shading of the radiated sound. This may be a headphone act small and smallest design, since the coaxial transducer in headphones in conventionally arranged and the control of the localizability of the sound event realized in that areas of the woofer and the tweeter be covered or damped in a targeted manner.

Ein Stereo-Kopfhörer zur Vorne-Ortbarkeit von von ihm erzeugten Schallereignissen wird durch die Merkmale des Anspruchs 8 bereitgestellt. Demnach sind die durchlässigen Bereiche bzw. abgeschatteten Bereiche der Schallwände des Kopfhörers so angeordnet, daß Schall in gezielter Weise abwärts abgestrahlt wird. Hierdurch wird überraschenderweise eine Vorne-Ortbarkeit in derselben Qualität erreicht wie mit dem einleitend genannten Vorschlag des Erfinders, Schallwandler nach vorn und unten verschoben gegenüber der herkömmlichen Anordnung anzuordnen.A stereo headphone for the front-Ortbarkeit of sound events generated by it is provided by the features of claim 8. Accordingly, the permeable areas or shaded areas of the baffles of the headphone arranged so that Sound is emitted in a targeted manner downwards. This is surprisingly achieved a front-Ortbarkeit in the same quality as with the introduction mentioned Proposal of the inventor, sound transducers moved forward and downwards relative to the to arrange conventional arrangement.

Ein Surround-Kopfhörer mit der Möglichkeit der Vorne-Ortbarkeit der vorderen Stereo-Mitten-Kanäle und einer Ortbarkeit der hinteren und der Seitenkanäle, der sogenannten Surround-Kanäle getrennt hiervom wird durch die Merkmale des Anspruchs 9 geschaffen. Ausgehend von dem Stereo-Kopfhörer mit Vorne-Ortbarkeit wird gemäß diesem Vorschlag ein zweiter Satz von Schallwandlern gespiegelt in einer Horizontalebene zum ersten Satz von Schallwandlern an einer Horizontalebene in bezug auf den Kopf eines Nutzers angeordnet, um die Surround-Kanäle getrennt von den Stereo-/Mitten-Kanälen lokalisieren zu können. Doch hierbei handelt es sich um eine extrem einfache Maßnahme zur Differenzierung von per Kopfhörer wiedergegebenen Schallfeldern in wirksamer Weise.A surround headphone with the ability to front-locate the front stereo center channels and a traceability of the rear and side channels, the so-called Surround channels separated herevom is provided by the features of claim 9. Starting from the stereo earphones with front-orbitability is according to this proposal a second set of transducers mirrored in a horizontal plane to the first Set of transducers on a horizontal plane with respect to the head of a user arranged to locate the surround channels separately from the stereo / center channels to be able to. But this is an extremely simple measure of differentiation of sound fields reproduced by headphones in an effective manner.

Nachfolgend wird die Erfindung anhand der Zeichnung beispielhaft näher erläutert; es zeigen:

The invention will be explained in more detail by way of example with reference to the drawing; show it:

a plan view of a baffle of one of two housings of a headset, which is useful as stereo headphones with front-localization, and
Fig. 2
a plan view of a baffle of one of two housings of a headset, which is useful as a surround headphones with front-localization.

In Fig. 1 ist die Schallwand von einem der rechten und linken Gehäuse eines Stereo-Kopfhörers in Draufsicht gezeigt und allgemein mit der Bezugsziffer 10 bezeichnet. Bei der dargestellten Ausführungsform besitzt die Schallwand im wesentlichen die Form einer Kreisscheibe. Alternativ kann die Form der Schallwand 10 auch Ellipsenform besitzen. Innerhalb ihre schallundurchlässigen Innenrands umfaßt die Schallwand 10 Abschnitte hoher Schalldämpfung und Abschnitte freier Schalldurchlässigkeit. Soweit vorliegend die Rede von freier Schalldurchlässigkeit ist, kann es sich im Vergleich zu den Abschnitten hoher Dämpfung auch um solche wesentlich geringerer Dämpfung (unter Dämpfung ist vorliegende Schalldämpfung zu verstehen), jedoch nicht vollständig ungehinderter Schalldurchlässigkeit handeln.In Fig. 1, the baffle of one of the right and left cases of a stereo headphone shown in plan view and generally designated by the reference numeral 10. at In the illustrated embodiment, the baffle has substantially the shape of a Circular disk. Alternatively, the shape of the baffle 10 may also have elliptical shape. Within its sound-proof inner edge, the baffle comprises 10 sections high sound attenuation and sections of free sound transmission. As far as the present Talk about free sound transmission, it can be compared to the sections high attenuation even to such much lower attenuation (under damping to understand existing sound attenuation), but not completely unhindered sound transmission act.

Auf der Rückseite der in Fig. 1 gezeigten Schallwand 10 (unterhalb der Zeichnungsebene) befindet sich ein koaxiales Schallwandlersystem, umfassend einen Mitten-Tieftöner 12 und einen Hochtöner 13. Der Mitten-Tieftöner 12 besitzt naturgemäß einen größeren Durch messer als der Hochtöner 13 und er schließt sich einwärts unmittelbar an den Innenrand 11 des schallundurchlässigen kreisförmigen Bereichs 11 der Schallwand 10 an. Im Zentrum des Mitten-/Tieftöners 12 ist der Hochtöner 13 angeordnet. Unter Aussparung des Hochtöners 13 weist die Schallwand 10 zwischen dessen kreisförmiger Außenkontur und der kreisförmigen Außenkontur des Mittentieftöners 12, entsprechend dem Innenrand des kreisförmigen Bereichs 11 einen ersten Abschnitt 14 hoher Dämpfung auf. Der erste Abschnitt 14 hoher Dämpfung erstreckt sich bezogen auf das Zentrum der Schallwandler 12, 13 auf einen Kreisteilbereich größer als 170° und kleiner als 340° unter Freilassung eines allgemein V-förmigen bzw. trapezförmigen Bereichs 15, der keine, oder im Vergleich zu Abschnitt 14, nur eine geringe Dämpfung besitzt. Dieser V-förmige Bereich 15 besitzt einen Öffnungswinkel < 170° und > 20°, bevorzugt < 100° und > 50° und besonders bevorzugt von etwa 70°. Bei der dargestellten Ausführungsform ist der erste Abschnitt 14 hoher Dämpfung begrenzt von geradlinigen Rändern 16a und 16b, die den trapezförmigen Bereich 15 seitlich festlegen der an seiner großen Basis durch ein Krfeissegment 15a und an seiner kleinen Basis durch ein Kreissegment 15b des Hochtöners 13 des Innenrands 11. Die Ränder 16a, 16b enden innenliegend am Rand des Hochtöners 13, der durch den ersten Abschnitt 14 hoher Dämpfung nicht abgedeckt ist.On the back of the baffle 10 shown in FIG. 1 (below the plane of the drawing) is a coaxial transducer system comprising a center woofer 12 and a tweeter 13. The midrange woofer 12 naturally has a larger diameter knife as the tweeter 13 and it closes inwards directly to the inner edge 11th the sound-impermeable circular portion 11 of the baffle 10 at. Downtown of the mid / woofer 12, the tweeter 13 is arranged. Under recess of the tweeter 13 has the baffle 10 between the circular outer contour and the circular outer contour of the mid-woofer 12, corresponding to the inner edge of the circular portion 11 a first portion 14 of high attenuation. The first paragraph 14 high attenuation extends with respect to the center of the sound transducer 12, 13 to a circle portion greater than 170 ° and less than 340 °, leaving a generally V-shaped or trapezoidal region 15, none, or compared to Section 14, only has a low attenuation. This V-shaped area 15 has a Opening angle <170 ° and> 20 °, preferably <100 ° and> 50 ° and particularly preferred of about 70 °. In the illustrated embodiment, the first portion 14 is higher Attenuation is limited by rectilinear edges 16a and 16b, which are the trapezoidal region 15 laterally determine the at its large base by a Krfeissegment 15 a and at its small base through a circle segment 15b of the tweeter 13 of the inner edge eleventh The edges 16a, 16b terminate internally at the edge of the tweeter 13 passing through the first Section 14 high attenuation is not covered.

Durch den ersten Abschnitt 14 hoher Dämpfung wird erreicht, daß von dem Mitten/Tieftöner 12 erzeugter Schall ausschließlich bzw. zum größten Teil ausschließlich über den V-förmigen Bereich 15 an das Ohr eines Nutzers gelangt, der den Stereo-Kopfhörer aufgesetzt hat. Dies hat den Vorteil, daß eine relativ große Fläche, nämlich die Fläche des Abschnitts 14 und die Fläche des Innenrands 11 als Schallwand für tiefe und mittelhohe Töne dient.By the first portion 14 high attenuation is achieved that of the center / woofer 12 generated sound exclusively or for the most part exclusively on the V-shaped portion 15 reaches the ear of a user of the stereo headphones has set. This has the advantage that a relatively large area, namely the area of the Section 14 and the surface of the inner edge 11 as a baffle for low and medium high Sounds serves.

Der Hochtöner 13 ist ebenfalls partiell abgedeckt, und zwar durch einen zweiten Abschnitt 17 hoher Dämpfung. Dieser Bereich 17 kommt im Bereich der Spitze des V-förmigen Bereichs 15 zu liegen und läßt zwischen 5% und 50%, bevorzugt zwischen 5% und 25% des Hochtöners, und besonders bevorzugt etwa 15% des Hochtöners frei. Hierdurch wird erreicht, daß der größte Teil des vom Hochtöner 13 abgestrahlten Schalls ungehindert zum Ohr eines Nutzers gelangt, der den Stereo-Kopfhörer aufgesetzt hat, wobei dieser Anteil des Schalls in Fig. 1 im wesentlichen abwärts gerichtet ist. Es wird davon ausgegangen, daß der Nutzer den Stereo-Kopfhörer so aufgesetzt hat, daß die Schallwand 10 die in Fig. 1 gezeigte Ausrichtung besitzt mit abwärts weisendem nicht abgedeckten Teil des Hochtöners 13 und aufwärts weisender Spitze des V-förmigen Bereichs 15. Die Praxis hat überraschend gezeigt, daß durch eine derartige gezielte Abschattung des abgestrahlten Schallereignisses die bei herkömmlichen Kopfhörern angetroffene Im-Kopf-Lokalisation überführt wird in eine Ortbarkeit des Schallereignisses vor dem Kopf eines Nutzers des Stereo-Kopfhörers.The tweeter 13 is also partially covered, through a second section 17 high damping. This area 17 comes in the area of the top of the V-shaped area 15 and leaves between 5% and 50%, preferably between 5% and 25% of Tweeter, and more preferably about 15% of the tweeter free. This will achieve that the largest part of the radiated from the tweeter 13 sound unhindered for Ear of a user who has put on the stereo headphones, which share of the sound in Fig. 1 is directed substantially downwards. It is assumed, that the user has placed the stereo headphones so that the baffle 10 in Fig. 1 shown alignment has with down-facing uncovered part of the tweeter 13 and upwardly pointing tip of the V-shaped area 15. The practice is surprising shown that such a targeted shading of the emitted sound event transferred the encountered in conventional headphones in-head localization is in a traceability of the sound event in front of the head of a user of the stereo headphone.

Wie in Fig. 1 gezeigt, ist der zweite Abschnitt 17 hoher Dämpfung, der vor dem Hochtöner 13 zu liegen kommt, durch einen geraden Rand 18 begrenzt, der bei Nutzung des Stereo-Kopfhörers in etwa in einer Horizontalebene, bezogen auf den Kopf des Nutzers zu liegen kommt.As shown in Fig. 1, the second high-attenuation portion 17 is in front of the tweeter 13 comes to rest, limited by a straight edge 18, when using the stereo headphone to lie approximately in a horizontal plane, relative to the head of the user comes.

Fig. 2 zeigt eine Surround-Variante des Kopfhörers von Fig. 1, bei welchem das koaxiale Schallwandlersystem doppelt vorgesehen ist. Für gleiche Teile sind in Fig. 1 und Fig. 2 dieselben Bezugsziffern verwendet.Fig. 2 shows a surround variant of the headphone of Fig. 1, in which the coaxial Sound transducer system is provided in duplicate. For the same parts are shown in Fig. 1 and Fig. 2 the same reference numerals used.

Die Schallwandlereinheit 12, 13 von Fig. 1 ist in Fig. 2 entlang einer Spiegelebene S gespiegelt unter Erzeugung einer zweiten Schallwandlereinheit 12', 13', die denselben internen Aufbau auch bezüglich der Abschnitte hoher Dämpfung besitzt, wie die erste Schallwandlereinheit 12, 13, jedoch in bezug auf diese auf den Kopf stehend. Das heißt, der V-förmige Bereich 15' der zweiten Schallwandlereinheit 12', 13' weist mit seiner Spitze abwärts in Richtung zur Spitze des V-förmigen Bereichs 15 der ersten Schallwandlereinheit 12, 13, der zweite Abschnitt hoher Dämpfung 17' weist zum zweiten Abschnitt 17 hoher Dämpfung der ersten Schallwandlereinheit 12, 13, so daß die freien, schwach bedämpften bzw. nicht bedämpften Bereiche der zweiten Schallwandlereinheit 12', 13' in Fig. 2 nach oben weisen.The sound transducer unit 12, 13 of FIG. 1 is mirrored in FIG. 2 along a mirror plane S. forming a second transducer unit 12 ', 13', the same internal Structure also with respect to the portions of high attenuation possesses, as the first sound transducer unit 12, 13, but upside down with respect to these. That is, the V-shaped Area 15 'of the second sound transducer unit 12', 13 'points downward with its tip towards the top of the V-shaped region 15 of the first transducer unit 12, 13, the second portion of high damping 17 ', the second portion 17 is higher Attenuation of the first transducer unit 12, 13, so that the free, weakly damped or non-damped areas of the second sound transducer unit 12 ', 13' in FIG. 2 at the top.

Ein auf Grundlage von Fig. 2 aufgebauter Kopfhörer ist als Surround-Kopfhörer nutzbar, wobei die erste Schallwandlereinheit 12, 13 den Schall für einen vorderen Kanal bzw. den vorderen Mittenkanal abstrahlt, während die zweite Schallwandlereinheit 12', 13' einen Surround-Kanal abstrahlt. Hierdurch wird erreicht, daß die vorderen Kanäle bzw. der vordere Mittenkanal eines Surround-Schallfeldes vor dem Kopf eines Nutzers ortbar ist, während die Surround-Kanäle im wesentlichen in einer Ebene ortbar sind, die hinter dem Kopf eines Nutzers sowie seitlich von diesem liegt.A built-up on the basis of Fig. 2 headphones is available as a surround headphones, wherein the first transducer unit 12, 13 the sound for a front channel or the front center channel radiates, while the second sound transducer unit 12 ', 13' a Surround channel radiates. This ensures that the front channels or the front Center channel of a surround sound field in front of the head of a user is locatable while the surround channels are located essentially in one plane, behind the head of a user and laterally from this.
