Die Erfindung betrifft einen kegelförmigen Lautsprechervorsatz gemäß Patentanspruch 1 und
eine Lautsprecheranordnung gemäß den Patentansprüchen 2 und 3.The invention relates to a conical speaker attachment according to claim 1 and
a loudspeaker arrangement according to
Lautsprecher weisen stets einen vorgegebenen Winkelbereich auf, in dem der Schall abgestrahlt wird. Dieser Winkelbereich liegt in der Regel zwischen 60° und 155°. Bedingt durch diese technische Vorgabe wird nur jener Raum optimal beschallt, der innerhalb dieses Winkelbereichs liegt. Außerhalb dieses Bereichs ist mit einer reduzierten Tonwiedergabe und verminderter Qualität zu rechnen.Loudspeakers always have a predetermined angular range in which the sound is emitted becomes. This angular range is usually between 60 ° and 155 °. Due this technical specification only optimally sonicates that room within this angular range lies. Outside of this range is with a reduced sound and reduced quality.
Diese Situation ist in Fig.1a,b dargestellt, wobei Lautsprecher in regelmäßigen Abständen in der Verkleidung der Decke eingebaut sind, wie es beispielsweise in Hotelhallen, Krankenhausfluren, oder auch Reisebussen der Fall ist. Wenn die Musik oder die akustische Nachricht mit einer gedämpften Lautstärke abgestrahlt wird, ist der akustische Empfang für Personen, die sich in den Bereichen A direkt unterhalb der Lautsprecher aufhalten, noch verhältnismäßig gut. Jene Personen aber, welche sich in den Bereichen B zwischen den Lautsprechern befinden, empfangen die Musik oder sonstige akustische Nachricht nur in abgeschwächter Form. Wenn jedoch die Schallwellen mit relativ großer Lautstärke, wie beispielsweise in Diskotheken ausgestrahlt werden, sind die Verhältnisse wiederum derart, daß in unmittelbarer Nähe der Lautsprecher der Lärmpegel unerträglich wird, da dort der Empfang der Schallwellen auf direkte Weise erfolgt, wie auch in Fig.1c dargestellt ist.This situation is shown in Fig.1a, b, with speakers at regular intervals the cladding of the ceiling are installed, such as in hotel halls, hospital corridors, or coaches is the case. If the music or the acoustic message is emitted with a subdued volume, the acoustic reception is for people that are in areas A directly below the speakers are still proportionate Well. However, those people who are in areas B between the loudspeakers receive the music or other acoustic message only in a weakened form. However, when the sound waves with a relatively high volume, such as in discos are broadcast, the conditions are such that in immediate Near the speakers the noise level becomes unbearable because there the reception of the sound waves is done in a direct manner, as also shown in Fig.1c.
Nach dem Stand der Technik kann ein optimaler Musik- oder Sprachempfang somit nur durch Wahl einer geeigneten Empfangsposition oder Verwendung von Kopfhörern erreicht werden kann.According to the state of the art, optimal music or speech reception can only be achieved by Selection of a suitable reception position or use of headphones can be achieved can.
Es ist demgemäß Aufgabe der vorliegenden Erfindung, eine Einrichtung anzugeben, mit der eine gleichmäßige Beschallung eines Raumes ermöglicht werden kann.It is accordingly an object of the present invention to provide a device with which uniform sound reinforcement of a room can be made possible.
Diese Aufgabe wird durch die Merkmale der Patentansprüche 1 bis 3 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.This object is solved by the features of claims 1 to 3. Beneficial Refinements are specified in the subclaims.
Die Erfindung besteht aus einem kegelförmigen Lautsprechervorsatz, welcher derart vor einen serienmäßigen Lautsprecher montiert wird, daß die Kegelspitze auf den Lautsprecher gerichtet ist. Die Schallwellen werden durch Reflexion an dem schallreflektierenden Kegelmantel umgelenkt und treten durch eine Öffnung zwischen dem Vorsatz und dem Lautsprecher und dem Lautsprechergehäuse nach allen Seiten aus, wodurch eine gleichmäßige Beschallung von Räumen erreicht wird. In dem Lautsprechervorsatz können auch zusätzlich Durchgangsöffnungen vorgesehen sein, um einen bestimmten Anteil Direktabstrahlung der Schallwellen zu erzielen. Gegenstand der Erfindung ist ebenfalls eine Lautsprecheranordnung bestehend aus einem Lautsprecher und einem an diesen montierten Lautsprechervorsatz mit den vorstehend beschriebenen Eigenschaften sowie eine Lautsprecheranordnung bestehend aus einem in ein Gehäuse eingebauten Lautsprecher und einem mit dem Gehäuse verbundenen Lautsprechervorsatz mit den vorstehend beschriebenen Eigenschaften.The invention consists of a cone-shaped speaker attachment, which in front of one standard loudspeaker is mounted so that the cone tip is directed towards the loudspeaker is. The sound waves are deflected by reflection on the sound-reflecting cone jacket and pass through an opening between the header and the speaker and the Loudspeaker housing on all sides, creating a uniform sound from Clearing is achieved. Through openings can also be provided in the loudspeaker attachment be provided to a certain proportion of direct radiation of the sound waves achieve. The invention also relates to a loudspeaker arrangement consisting of a speaker and a speaker attachment mounted thereon with the above described properties and a loudspeaker arrangement consisting of one in one Built-in speaker and a speaker attachment connected to the housing with the properties described above.
Die Erfindung wird im folgenden anhand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert.The invention is described below with reference to exemplary embodiments shown in the drawings explained in more detail.
Es zeigen:

Der Verlauf des Kegelmantels des Lautsprechervorsatzes 3 ist vorzugsweise derart, daß die
auf die Oberfläche des Kegelmantels auftreffenden Schallwellen in einem Winkelbereich von
90° bis 135° umgelenkt werden. Dies wird durch einen im Querschnitt exponentiellen Verlauf
des Kegelmantels wie in Fig.2 erreicht.The course of the cone of the
In Fig.3 ist ein Ausführungsbeispiel eines erfindungsgemäßen Lautsprechervorsatzes 3 in einer
perspektivischen Darstellung von schräg oben gezeigt. Auf der dem Lautsprecher 2 zugewandten
schallreflektierenden Oberfläche sind in diesem Ausführungsbeispiel eine Anzahl
von Stabilisierungsrippen 4 angebracht, die von der Kegelspitze aus bis zu dem Außenrand
verlaufen. Der Lautsprechervorsatz 3 kann ferner mit Schrauben 5 und Abstandshülsen 6 geeignet
gewählter Länge an der Gehäusewand befestigt werden.3 shows an embodiment of a
Figur 4 zeigt die Verwendung von erfindungsgemäßen Lautsprechervorsätzen bei einem
Standlautsprecher, der einen Hochtonlautsprecher 7 und einen Tieftonlautsprecher 8 aufweist.
Zusätzlich kann eine Zierabdeckung 9 vorgesehen sein, die mit Distanzstücken 10 geeigneter
Länge und Befestigungselementen 11, beispielsweise Doppel-Klettverschlüssen an das Gehäuse
1 befestigt wird.Figure 4 shows the use of speaker attachments according to the invention in a
Tower speaker, which has a
Anstelle einer Montage mit Schrauben und Abstandshülsen können bei der Befestigung des Lautsprechervorsatzes und/oder der Zierabdeckung auch Stanzteile zum Einsatz kommen, mit denen ebenso eine schnelle und sichere Verbindung ermöglicht werden kann.Instead of mounting with screws and spacers, you can attach the Loudspeaker attachment and / or the decorative cover also use stamped parts which can also enable a fast and secure connection.
In Fig.5 ist der erfindungsgemäße Lautsprechervorsatz 3 an einen in eine Paneele 12 eingebauten
Lautsprecher 2 befestigt. Ein großer Teil der Schallwellen wird also unmittelbar nach
der Reflexion an der Oberfläche des Lautsprechervorsatzes an der Oberfläche der Paneele
nach unten reflektiert. In Figure 5, the
In Fig.6a,b ist dargestellt, wie - im Gegensatz zu Fig.1a,b - der Raum C unterhalb der Deckenlautsprecher gleichmäßig beschallt wird. Wie gezeigt in Fig.6b, gelangen die Schallwellen direkt unterhalb der Lautsprecher anders als in Fig.1b auf indirekte Weise zu der Empfangsperson. Wie in Fig.6a, b zu sehen ist, gelangt bei dieser Ausführungsform jedoch auch ein Anteil direkt abgestrahlter Schallwellen zu der Empfangsperson, um einen Stereoeffekt zu erzielen. Zu diesem Zweck sind Durchgangsöffnungen in dem Lautsprechervorsatz vorgesehen, wie noch beschrieben werden wird.In Fig. 6a, b it is shown how - in contrast to Fig. 1a, b - the space C below the Ceiling speakers are evenly sounded. As shown in Fig.6b, the sound waves arrive directly below the loudspeakers, unlike in Fig. 1b, in an indirect way to the recipient. As can be seen in FIGS. 6a, b, this embodiment also works a portion of directly emitted sound waves to the recipient to create a stereo effect achieve. For this purpose, through openings are provided in the loudspeaker attachment, as will be described later.
Fig.7 zeigt schließlich die Schallwellenausstrahlung bei zwei Standlautsprechern (Boxen) unter Verwendung des erfindungsgemäßen Lautsprechervorsatzes. Vorzugsweise werden die Boxen so aufgestellt, daß die Lautsprecher nach oben gerichtet sind, so daß sich die Lautsprechervorsätze oben befinden. Von jeder Box werden horizontal nach allen Seiten Schallwellen abgestrahlt. Durch die horizontale 360°-Abstrahlung und die Reflexion an den Wänden wird eine gleichmäßige Beschallung des Raumes erreicht. Dies wurde in der Praxis dadurch erprobt, daß Testpersonen im Raum mit verbundenen Augen den Standort der Box bestimmen sollten. Es zeigte sich dabei, daß dies im Vergleich zu der konventionellen Verwendung der Standlautsprecher gemäß Fig.1c erheblich erschwert ist. Durch die erschwerte Standortbestimmung der Boxen sowie die nicht vorhandenen direkten, geraden Schallwellen entsteht eine Art "Raumklang", durch den sämtliche Töne durch die natürliche Reflexion des Schalls an den Wänden des Raumes angenehmer und sauberer erklingen. Auch hier kann zusätzlich ein Anteil nach oben gerichteter direkt abgestrahlter Schallwellen infolge der Wirkung der Durchgangsöffnungen erzeugt werden.Fig. 7 shows the sound wave emission from two floorstanding speakers (boxes) below Use of the speaker attachment according to the invention. Preferably the Boxes set up so that the speakers face upwards so that the speaker attachments located above. Sound waves are horizontal from each box on all sides emitted. Due to the horizontal 360 ° radiation and the reflection on the walls uniform sound distribution in the room. This has been tried in practice by that test subjects in the blindfolded room determine the location of the box should. It was found that this is compared to the conventional use of the Floorstanding speaker according to Fig.1c is considerably more difficult. Due to the difficult location of the boxes and the non-existent direct, straight sound waves a kind of "spatial sound", through which all tones through the natural reflection of the sound sound more pleasant and cleaner on the walls of the room. Here, too, can be additional a proportion of upward directed sound waves due to the effect of the Through openings are generated.
Die schallreflektierende Oberfläche des Lautsprechervorsatzes kann in verschiedener Weise ausgebildet sein. Sie kann sowohl durchgehend als auch unterbrochen, d.h. mit entlang der Zylinderachse des Vorsatzes durchgehenden Öffnungen oder Kanälen versehen geformt sein. Durch die Durchgangsöffnungen kann ein bestimmter Anteil der Schallwellen hindurchtreten, so daß eine nach Maßgabe dieses Anteils vorwärtsgerichtete, direkte Beschallung erreicht wird. Eine solche Ausführungsform ist insbesondere zur Erzielung des Stereoeffektes wünschenswert, aber auch dann, wenn der Lautsprecher in sehr großer Höhe (z.B. in Flughafenhallen) montiert ist und eine Kombination von senkrechten und waagrechten Richtungen der Schallausbreitung erreicht werden soll.The sound reflecting surface of the speaker attachment can be in different ways be trained. It can be both continuous and interrupted, i.e. with along the Cylinder axis of the attachment provided through openings or channels. A certain proportion of the sound waves can pass through the through openings, so that a direct, direct sound is achieved in accordance with this proportion becomes. Such an embodiment is particularly desirable to achieve the stereo effect, but also if the loudspeaker is at a very high height (e.g. in airport halls) is mounted and a combination of vertical and horizontal directions of the Sound propagation should be achieved.
Bei einer Ausführungsform mit Durchgangsöffnungen können diese einerseits in ihrem Querschnitt fest vorgegeben sein, so daß stets ein gleichbleibender Anteil an direkt abgestrahlten Schallwellen erzeugt wird. Es kann aber auch vorgesehen sein, daß der Anteil der Direktabstrahlung kontinuierlich einstellbar ist. Dies kann dadurch erreicht werden, daß der Lautsprechervorsatz aus einem Reflektorteil und einem Deckelteil gefertigt ist, die zylindersymmetrisch sind und Durchgangsöffnungen aufweisen und um die Zylinderachse gegeneinander verdrehbar sind. Der Reflektorteil ist dabei dem Lautsprecher zugewandt und der Deckelteil ist auf der dem Lautsprecher abgewandten Seite des Reflektorteils angeordnet. Wenn die Durchgangsöffnungen miteinander zur Deckung gebracht werden, wird der Anteil an Direktabstrahlung maximal. Durch Verdrehen von Reflektorteil und Deckelteil gegeneinander kann dann der Anteil der Direktabstrahlung vermindert werden. Die Durchgangsöffnungen können vorzugsweise durch den Kunden selbst in einfacher Weise hergestellt werden, indem in Reflektorteil und Deckelteil Sollbruchstellen für die Durchgangsöffnungen vorgesehen sind. Die Durchgangsöffnungen können die Form von Kreissegmenten, also dreieckige Form, haben, beispielsweise die Form von 4 punktsymmetrisch angeordneten Kreissegmenten haben, wobei jedes Kreissegment einen Winkelbereich zwischen 15° und 20° überdeckt. Diese Kreissegmente können z.B. jeweils zwischen 2 Stabilisationsrippen, wie in Fig.3 gezeigt, angeordnet sein. Vorzugsweise ist der Reflektorteil feststehend angeordnet, während der Deckelteil um 360° dagegen verdrehbar ist. Somit kann durch stufenloses, manuelles Drehen des Deckelteils sowie durch wahlweises Durchbrechen der Durchgangsöffnungen im Reflektor- wie im Deckelteil das Volumen der Direktabstrahlung individuell gesteuert werden.In one embodiment with through openings, these can have a cross-section on the one hand be fixed so that there is always a constant proportion of directly emitted Sound waves is generated. But it can also be provided that the proportion of direct radiation is continuously adjustable. This can be achieved by using the speaker attachment is made of a reflector part and a cover part, which is cylinder symmetrical are and have through openings and against each other about the cylinder axis are rotatable. The reflector part faces the loudspeaker and the cover part is arranged on the side of the reflector part facing away from the loudspeaker. If the Through openings are made to coincide with each other, the proportion of direct radiation maximum. By rotating the reflector part and cover part against each other the proportion of direct radiation can then be reduced. The through openings can preferably be manufactured by the customer in a simple manner by In the reflector part and cover part, predetermined breaking points are provided for the through openings are. The through openings can have the shape of circular segments, i.e. triangular shape, have, for example, the shape of 4 circle segments arranged in a point-symmetrical manner, each segment of the circle covers an angular range between 15 ° and 20 °. These circular segments can e.g. each arranged between 2 stabilization ribs, as shown in Fig.3 be. The reflector part is preferably arranged to be stationary, while the cover part can be rotated by 360 °. Thus, by stepless, manual turning of the Cover part and by optionally breaking through the openings in the reflector-like the volume of direct radiation can be individually controlled in the cover part.
Ferner kann die schallreflektierende Oberfläche des Lautsprechervorsatzes entweder glatt als auch mit einer unebenen Oberfläche oder mit Absätzen gebildet sein.Furthermore, the sound reflecting surface of the speaker attachment can either be smooth also be formed with an uneven surface or with paragraphs.
Der Lautsprechervorsatz kann einzeln hergestellt und angeboten werden. Ebenso ist auch eine Lautsprecheranordnung denkbar, bei der der Vorsatz entweder direkt mit dem Lautsprecher oder dem Gehäuse fest verbunden wird und die Anordnung als Einheit hergestellt und angeboten wird.The speaker attachment can be manufactured and offered individually. There is also one Loudspeaker arrangement conceivable, in which the attachment either directly with the loudspeaker or the housing is firmly connected and the arrangement manufactured and offered as a unit becomes.
Der erfindungsgemäße Lautsprechervorsatz kann im Spritzgußverfahren aus Thermoplasten, in bevorzugter Weise sogar aus Recyclingmaterial, gefertigt werden. Im übrigen kann der Lautsprechervorsatz für alle gängigen, handelsüblichen Lautsprecher entsprechend der unterschiedlichen Durchmesser hergestellt werden. Eine Veränderung der technischen Merkmale am Lautsprecher ist nicht erforderlich.The loudspeaker attachment according to the invention can be injection molded from thermoplastics, preferably even made from recycled material. Otherwise, the Speaker attachment for all common, commercially available speakers according to the different Diameter can be produced. A change in the technical characteristics on the speaker is not necessary.
