Description

Die vorliegende Erfindung betrifft eine tragbare Vorrichtung zur Übertragung von Schall mit einem Gehäuse und mindestens einem Schallübertragungsmittel, wobei das Schallübertragungsmittel am Körper einer Person angeordnet ist, derart, daß sich ein Schallübertragungsweg vom Schallübertragungsmittel über die Eustachi-Röhre zu den Gehörknöchelchen der Person ergibt.The present invention relates to a portable device for transmitting sound with a Housing and at least one sound transmission means, wherein the sound transmission means is arranged on the body of a person such that a sound transmission path from Sound transmission means through the Eustachi tube to the person's ear bones.

Eine derartige Vorrichtung ist aus der DE 196 09 554 C1 bekannt. Zudem beschreibt die DE 196 09 554 das grundlegende Verfahren zur Übertragung von Schall mittels einer Schallübertragungsquelle, die direkt am Körper einer Person angeordnet ist, so daß sich ein direkter Schallübertragungsweg von dem Schallübertragungsmittel über die Eustachi-Röhre zu den Gehörknöchelchen der Person ergibt. Dadurch ergibt sich eine besonders klangintensive Übertragung von durch das Schallübertragungsmittel ausgesendeten Tönen.Such a device is known from DE 196 09 554 C1. DE 196 also describes 09 554 the basic method of transmitting sound using a sound transmission source, which is placed directly on the body of a person, so that there is a direct sound transmission path from the sound transmission medium via the Eustachi tube to the ossicles of the person. This results in a particularly sound-intensive transmission of tones emitted by the sound transmission means.

Auch die DE 197 13 142 A1 beschreibt einen Knochenübertragungs-Lautsprecher, der einer Person die Wahrnehmung akustischer Töne, wie beispielsweise Musik, ermöglicht. Der bekannte Knochenübertragungs-Lautsprecher wird dabei mittels eines Befestigungssystems an dem Körper der Person befestigt, vorzugsweise anliegend an das Sternum.DE 197 13 142 A1 also describes a bone transmission loudspeaker that is used by a person enables the perception of acoustic tones, such as music. The known Bone transmission speaker is attached to the body by means of a fastening system attached to the person, preferably adjacent to the sternum.

Nachteilig an den bekannten gattungsgemäßen Vorrichtungen zur Übertragung von Schall ist jedoch, daß die Qualität der Schallübertragung, und damit die akustische Qualität, nur sehr mangelhaft ist. A disadvantage of the known generic devices for transmitting sound is, however, that the quality of the sound transmission, and thus the acoustic quality, is only very poor is.

Es ist daher Aufgabe der vorliegenden Erfindung, eine gattungsgemäße Vorrichtung zur Übertragung von Schall bereitzustellen, die eine verbesserte Übertragung von Schall, und damit eine bessere Akustik, gewährleistet.It is therefore an object of the present invention to provide a generic device for transmission of sound to provide an improved transmission of sound, and thus a better acoustics, guaranteed.

Gelöst wird diese Aufgabe mit einer Vorrichtung gemäß den Merkmalen des Hauptanspruches 1.This object is achieved with a device according to the features of main claim 1.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.Advantageous configurations are described in the subclaims.

Eine erfindungsgemäße tragbare Vorrichtung zur Übertragung von Schall weist mindestens ein Schallübertragungsmittel auf, das jeweils von mindestens einer in Richtung eines Körpers einer Person offen ausgebildeten, röhrenartigen Vorrichtung umgeben ist, so daß die röhrenartige Vorrichtung einen Schallraum zwischen dem Schallübertragungsmittel und dem Körper der Person ausbildet. Durch den zusätzlichen, neu gebildeten Schallraum zwischen dem Schallübertragungsmittel und dem Körper der Person ergibt sich überraschenderweise eine verbesserte Schallübertragung, und damit verbesserte Akustik, beim Übertragen von Schall vom Schallübertragungsmittel über die Eustachi-Röhre zu den Gehörknöchelchen der Person.A portable device for transmitting sound according to the invention has at least one Sound transmission means, each of at least one in the direction of a body one Person openly trained, tubular device is surrounded, so that the tubular device a sound space between the sound transmission means and the body of the person trains. Due to the additional, newly created sound space between the sound transmission means and the person’s body surprisingly has improved sound transmission, and thus improved acoustics when transmitting sound from the sound transmission means over the Eustachi tube to the person's ossicles.

In einer vorteilhaften Ausgestaltung der Erfindung weist die röhrenartige Vorrichtung eine kreisförmige oder elliptische oder rechteckige oder quadratische oder dreieckige oder vieleckige oder unregelmäßige Querschnittsform auf. Es ist auch möglich, daß die Form des Querschnitts der röhrenartigen Vorrichtung in etwa der geometrischen Ausgestaltung des Gehäuses der erfindungsgemäßen Vorrichtung entspricht. Dadurch ist gewährleistet, daß die röhrenartige Vorrichtung immer eng am Körper anliegt. Zudem fügt sich die röhrenartige Vorrichtung als Einzelelement ohne weiteres in die Ausgestaltung der anderen Elemente der tragbaren Vorrichtung ein, so daß die erfindungsgemäße Vorrichtung auch optisch ansehnlich ist.In an advantageous embodiment of the invention, the tubular device has a circular shape or elliptical or rectangular or square or triangular or polygonal or irregular cross-sectional shape. It is also possible that the shape of the cross section of the tubular device in approximately the geometric configuration of the housing of the invention Device corresponds. This ensures that the tubular device is always close to the body. In addition, the tubular device fits together as a single element easily in the design of the other elements of the portable device, so that the device according to the invention is also visually attractive.

In einer weiteren vorteilhaften Ausgestaltung besteht die röhrenartige Vorrichtung aus einem elastischen Material, zum Beispiel aus Kunststoff. Durch die Elastizität der röhrenartigen Vorrichtung wird das Anliegen beziehungsweise die Haftung der erfindungsgemäßen Vorrichtung beziehungsweise der röhrenartigen Vorrichtung am Körper erhöht, so daß ein dicht abgeschlossener Schallraum entsteht. Je dichter die Verbindung zwischen der röhrenartigen Vorrichtung und dem Körper ist, desto besser ist die Schallübertragung beziehungsweise die daraus resultierende Akustik. Die Wandstärke der röhrenartigen Vorrichtung kann dabei im Bereich zwischen 0,5 und 4,0 cm liegen. Dadurch ergibt sich eine entsprechend große Auflagefläche der röhrenartigen Vorrichtung am Körper mit den beschriebenen Vorteilen.In a further advantageous embodiment, the tube-like device consists of an elastic one Material, for example made of plastic. Due to the elasticity of the tubular device the concern or liability of the device according to the invention or the tubular device on the body increased so that a tightly sealed Sound space is created. The closer the connection between the tubular device and the Body, the better the sound transmission or the resulting acoustics. The wall thickness of the tube-like device can range between 0.5 and 4.0 cm. This results in a correspondingly large contact surface of the tubular device on the body with the advantages described.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Querschnittsfläche des von der röhrenartigen Vorrichtung gebildeten Schallraums größer als die entsprechende Querschnittsfläche des Schallübertragungsmittels. Dadurch ergibt sich vorteilhafterweise eine Volumenvergrößerung des sich ergebenden Schallraums mit einer entsprechenden Verbesserung der Schallübertragung. Dabei kann die röhrenartige Vorrichtung an dem in Richtung des Gehäuses weisenden Ende im Bereich des nicht von der Querschnittsfläche des Schallübertragungsmittels überlagerten Schallraums ein flach ausgebildetes Stützelement aufweisen. Dieses Stützelement dient einerseits zur Stabilisierung der röhrenartigen Vorrichtung und andererseits zur innigen Verbindung mit dem Gehäuse der tragbaren Vorrichtung.In a further advantageous embodiment of the invention, the cross-sectional area of the of the tube-like device formed sound space larger than the corresponding cross-sectional area of the sound transmission means. This advantageously results in an increase in volume of the resulting sound space with a corresponding improvement in sound transmission. The tube-like device can point towards the housing End in the area of that not overlaid by the cross-sectional area of the sound transmission means Sound space have a flat support element. This support element serves on the one hand to stabilize the tubular device and on the other hand for an intimate connection with the housing of the portable device.
