Description

Technisches GebietTechnical area

Die vorliegende Erfindung betrifft einen Kinnbügelempfänger gemäss Oberbegriff des Anspruchs 1.The present invention relates to a chin guard receiver according to the preamble of claim 1.

Stand der TechnikState of the art

Aus DE-33 25 031 C2 ist ein infrarot-Kopfhörer bekanntgeworden, welcher aus zwei über einen Kinnbügel miteinander verbundenen Wiedergabewandiem, aus einer Infrarot-Signale aufnehmenden und in Audio-Signale umwandeinden elektrischen Schaltung sowie aus zwei Mikrofonen mit nachgeordneten Mikrofonverstäkern besteht. Die Schaltung dieses infrarot-Kopfhörers ist so gehalten, dass den Wiedergabewandlem wahlweise die jeweils von der Infrarot-Schaltung bzw. den Mikrofonverstärkern abgeleiteten Signalen einzein oder in Kombination zugeführt werden. Dabei sind die Mikrofone mit einem Abstand voneinander am Kinnbügel derart angeordnet, dass sie sich symmetrisch zur Mediaebene des Kopfes eines Benützers befinden, wobei die von den Mikrofonen abgeleiteten Signale gegenphasig in gleichem Verhältnis dem jeweils anderen Mikrofonverstärker zugeführt werden.Out DE-33 25 031 C2 is an infrared headphone has become known, which consists of two connected via a chin guard Wiedergabewandiem, from an infrared signals receiving and convert into audio signals in the electrical circuit and two microphones with downstream Mikrofonverstäkern. The circuit of this infrared headphone is held so that the Wiederabevem either the respectively derived from the infrared circuit and the microphone amplifiers signals or singly or in combination are supplied. The microphones are arranged at a distance from each other on the chin guard in such a way that they are symmetrical to the media plane of the user's head, the signals derived from the microphones being supplied in opposite proportion to the respectively other microphone amplifier in opposite phase.

Dieser Infrarot-Kopfhörer steht dabei üblicherweise in Wirkverbindung mit einem Sender, der die emittierten Tonsignale, beispielsweise aus einem Fernseher oder aus einer HiFi-Anlage, in unsichtbare Infrarot-Strahlen umwandelt, und diese in den Raum abstrahlt, wo sie vom Infrarot-Kopfhörer empfangen werden, womit eine drahtlose Infrarot-Tonübertragung bereitgestellt werden kann. Sinnvollerweise ist ein solcher Sender zugleich Ladestation für den Infrarot-Empfänger und für mindestens einen Akku-Einsatz, der im aufgeladenen Zustand zum Betrieb des Infrarot-Kopfhörers eingesetzt wird.This infrared headphones is usually in operative connection with a transmitter, which converts the emitted sound signals, for example from a television or from a hi-fi system, into invisible infrared rays, and radiates them into the room, where they receive from the infrared headphones become, with which a wireless infrared sound transmission can be provided. It makes sense that such a transmitter at the same time charging station for the infrared receiver and for at least a rechargeable battery that is used when charged to operate the infrared headset.

Die Druckschrift WO 95/35011 A offenbart einen Infrarot-Kopfhörer als Kinnbügelempfänger ausgebildet. Dieser Infrarot-Kopfhörer besteht im wesentlichen aus einem Grundgehäuse, aus zwei Tragbügel mit je einem endseitig angeordneten Kleinlautsprecher. Die beiden Tragebügel sind im Grundgehäuse gelagert, wobei jene jeweils in Verbindung mit einem im Bereich der Lagerung wirkenden Federelement spreizbar sind, womit über diese Federelemente eine angenehme Ohransetzung der Kleinlautsprecher bewerkstelligt werden kann. Die In- und Ausserbetriebssetzung wird bei diesem Kopfhörer mittels eines handbetätigbaren Schalter vorgenommen.The publication WO 95/35011 A discloses an infrared earphone designed as a chin strap receiver. This infrared headphones consists essentially of a basic housing, two mounting brackets, each with a small speaker arranged end. The two support brackets are mounted in the base housing, wherein those in each case in conjunction with a force acting in the region of the bearing spring element can be spread, so on these spring elements a pleasant ear attachment of the miniature speaker can be accomplished. The in and Ausserbetriebssetzung is made in this headphone by means of a hand-operated switch.

Die Druckschriften GB 2 304 488 A und FR 2 280 283 A offenbaren ebenfalls kabelfreie Kopfhörer, bei welchen die spreizbaren als Kopfbügel konzipierten Bügelenden ebenfalls eine flexible Ohransetzung ermöglichen und in welche ein Ein-/AusSchalter integriert ist, dessen Ein-/Aus-Betätigung bügelsprelzabhängig ist, womit sich eine manuelle Betätigung des Schalters erübrigt.The pamphlets GB 2 304 488 A and FR 2 280 283 A also disclose wireless headphones, in which the expandable designed as a headband temple ends also allow flexible ear attachment and in which an on / off switch is integrated, the on / off operation is dependent brackets, which makes manual operation of the switch is unnecessary.

Alle die genannten zum Stand der Technik gehörenden Kopfhörer haben eines gemeinsam, dass die Kleinlautsprecher, auch Lautsprecher genannt, und deren Gehäuse fest mit den Tragbügeln des Kinnbügelsystems verbunden sind. Dabei trägt der Benutzer solcher Systeme den Kopfhörer vornehmlich jeweils in leicht vorgebeugter oder zurücklehnender Haltung, dergestalt, dass diese Systeme, unabhängig davon, ob der Benutzer stehend, sitzend oder gehend, aufgrund ihres Eigengewichts senkrecht nach unten hängen. Indessen, bei jeder noch so minimalen Aenderung der Position des Kopfes verändert sich die Lage der Kleinlautsprecher in den Ohrmuscheln gegenüber dem Gehörkanal, was zu folgenden Unzulänglichkeiten führt:

  1. a) Hierbei passen sich die Kleinlautsprecher jedesmal, auch bei jeder noch so kleinen Veränderung, der neuen Position an, was zu einer Reibung in den Ohrmuschein und im Gehörgang kommt, was der Benutzer wiederum als höchst unangenehm empfindet.
  2. b) Insbesondere bei Kleinlautsprechern, die den Gehörgang stöpsel- oder pfropfenähnlich verschliessen, verändert sich deren Lage zum Gehörgang. Dadurch verändern sich auch die urspranglichen akustischen Eigenschaften zum menschlichen Ohrsystem. Dies führt insbesondere bei Benutzern mit Hörver lusten in bestimmten Frequenzbereichen zu akustischen Veränderungen, welche in den meisten Fällen das optimale Hörempfinden beeinträchtigen, abgesehen davon, dass sich durch die unterschiedlichen Hörerdrücke zwischen dem einen zum anderen Ohr nachteilige Veränderungen der stereophonen Balance einstellen, welche dem Hörempfinden herabmindern.
  3. c) Aber auch bei Kleinlautsprechern, die parallel oder quasi-parallel zum Gehörgang geführt werden und den Gehörgang nur teilweise abschliessen, bewirkt jede neue Kopfposition eine Lageveranderung der Kleinlautsprecher zum Ohrmuschel/Gehörgang, was sich auf dem Tragkonfort negativ auswirkt und zu unangenehmen anfühlenden Lagen führt sowie das Hörempfinden negativ beeinflusst.
All of the mentioned belonging to the prior art headphones have one thing in common, that the small speakers, also called speakers, and their housing are firmly connected to the support brackets of the chin strap system. In this case, the user of such systems primarily wears the headphones in a slightly bent or reclining posture, such that these systems, regardless of whether the user is standing, sitting or walking, hang vertically downwards due to their own weight. However, with every change in the position of the head, the position of the small speakers in the earpieces changes with respect to the ear canal, which leads to the following shortcomings:
  1. a) Here, the small speakers adapt each time, even with any small change, the new position, resulting in a friction in the pinna and in the ear canal, which in turn feels the user to be extremely unpleasant.
  2. b) Especially for small speakers, the plugging or plug-like close the ear canal, their position changes to the ear canal. As a result, the urspranglichen acoustic properties to the human ear system change. This leads in particular in users with Hörver losses in certain frequency ranges to acoustic changes, which affect the optimal hearing in most cases, except that adjust by the different hearing pressures between one to the other ear adverse changes in stereophonic balance, which the hearing diminish.
  3. c) But even with small speakers, which are performed parallel or quasi-parallel to the ear canal and the auditory canal only partially complete, each new head position causes a change in position of the small speaker to the pinna / ear canal, which has a negative impact on the Tragkonfort and leads to unpleasant and sensitive layers as well as the sense of hearing negatively influenced.

Die DE 196 45 307 A1 offenbart einen Hörverstärker für einen Kopfhörer, insbesondere für einen Kinnbügelempfänger, der im Wesentlichen ein Grundgehäuse, zwei individuell geführte, über je ein Scharniergelenk gegenüber dem Grundgehäuse kippbar gelagerte Tragbügel und je einen endseitig an den Tragbügeln angeordneten Kleinlautsprecher vorsieht.The DE 196 45 307 A1 discloses a sound amplifier for a headphone, in particular for a chin guard receiver, which essentially provides a base housing, two individually guided, each hinged about a hinge joint against the base housing tiltably mounted mounting bracket and one end of the mounting brackets arranged small speaker.

Der WO 00/08893 A1 ist ein Kopfhörer zu entnehmen, an dessen beiden Tragbügelenden jeweils eine Lautsprechereinhit angebracht ist. In einer Ausführungsform sind die Lautsprechereinheiten an den Tragbügelenden schwenkbar montiert mittels einem nicht weiter aus der Druckschrift entnehmbaren Schwenkmechanismus.Of the WO 00/08893 A1 is to remove a headphone, at the two ends of each bracket a loudspeaker unit is attached. In one embodiment, the speaker units are pivotally mounted to the support bracket ends by means of a pivoting mechanism not further disclosed in the document.

Was hier die Technik anbelangt wird im wesentlichen auf die Ausführungen unter Fig. 1 verwiesen. Fig. 2 shows a Hörempfänger 200, which is designed as a stethoscope, in which case the sound transmission can also be accomplished by means of a cable. As far as the technology is concerned, the comments below are based essentially on the comments Fig. 1 directed.

Fig. 3 zeigt die Ausführungsform eines Kleinlautsprechers 300, der so ausgebildet ist, dass er den Gehörgang stöpsel- oder pfropfenahnlich verschliesst. Für die nähere Darstellung dieses Kleinlautsprechers 300 wird auf die Fig. 3a-3c, 5 verwiesen. Fig. 3 shows the embodiment of a miniature speaker 300, which is designed so that it closes the ear canal plug or Pfropfenschlichst. For the closer representation of this miniature speaker 300 is on the FIGS. 3a-3c, 5 directed.

Fig. 4 zeigt die Ausführungsform eines linsenförmigen Lautsprecherkörpers (405), der parallel oder quasi-parallel zum Gehörgang geführt wird, den Gehörgang demnach nur teilweise abschliesst und somit offen lässt. Für die nähere Darstellung dieses linsenförmigen Kleinlautsprechers 400 wird auf die Fig. 4a-4c und 6-8 verwiesen. Fig. 4 shows the embodiment of a lenticular loudspeaker body (405), which is performed parallel or quasi-parallel to the ear canal, the auditory canal therefore only partially completes and thus leaves open. For the closer representation of this lens-shaped small speaker 400 is on the Figs. 4a-4c and 6-8 directed.

Die Fig. 3a-3c zeigen den Kleinlautsprecher 300 in verschiedenen Ansichten. Im wesentlichen besteht ein solcher Kleinlautsprecher 300 aus einem Grundkörper 301, der ohrgangsseitig mit akustischen Tonöffnungen 307 und rückseitig mit weiteren akustischen Oeffnungen 302 versehen ist. Dem Grundkörper 301 angeschlossen ist der Tragbügel 303, der hier nur teilweise ersichtlich ist. Ohrseig weist der Kleinlautsprecher 300 einen pfropfenförmigen lautsprecherkörper 305 auf, der den Gehörgang abschliesst. Zwischen Grundkörper 301 und ohrseitigem Lautsprecherkörper 305 ist ein Kupplungsteil 308 mit angeschlossener Büchse 309 angeordnet, wobei die Verbindung der letzgenannten Teile 308 und 309 in Bezug auf Grundkörper 301 und Lautsprecherkörper 305 so konzipiert ist, dass zwischen letzterem 305 und Grundkörper 301 eine freie Drehbarkeit 306 eines bestimmten Winkels möglich ist. Mit dieser Weiterbildung lässt sich jede Veränderung der Kopfstellung beim Benutzer auffangen, dergestalt, dass die im Gehörgang lagemässig festsitzenden Lautsprecherkörper 305 des jeweiligen Kleinlautsprechers 300 durch ihre Drehbarkeit gegenüber dem Grundkörper 301 keinem Drehdruck ausgesetzt sind, wodurch eine Maximierung des Tragkonforts gepaart mit einem Höchstmass an Tonübertragungsqualität erreicht wird, da bei der letzteren Wirkung eine lagebedingte akustische Veränderungen bei der Tonübertragung wegfällt.The Fig. 3a-3c show the miniature speaker 300 in different views. Essentially, such a miniature loudspeaker 300 consists of a base body 301, which is provided on the output side with acoustic sound openings 307 and on the back side with further acoustic openings 302. The main body 301 is connected to the mounting bracket 303, which is only partially visible here. At the ear level, the miniature loudspeaker 300 has a plug-shaped loudspeaker body 305 which closes off the auditory canal. Between body 301 and ear-side speaker body 305, a coupling member 308 is arranged with a connected sleeve 309, wherein the connection of the last-mentioned parts 308 and 309 with respect to the base body 301 and speaker body 305 is designed so that between the latter 305 and the base body 301, a free rotation 306 of a certain angle is possible. With this development, any change in the head position can be absorbed by the user, such that the loudspeaker body 305 of the respective miniature loudspeaker 300 fixed in the auditory canal is not exposed to any rotational pressure due to its rotatability relative to the main body 301, thereby maximizing the wearing comfort combined with a maximum of sound transmission quality is reached, since in the latter effect a position-dependent acoustic changes in the sound transmission is eliminated.

Fig. 5 zeigt in einer Schnittebene den Aufbau eines solchen Kleinlautsprechers nach den Fig. 3a-3c. Wie oben bereits erwähnt, übernimmt der Kupplungsteil 308 die Verbindung zwischen Grundkörper 301 und Lautsprecherkörper 305, wobei dieser seinerseits mit einer Büchse 309 ergänzt ist, welche einerseits die Lagerung des Lautsprechers 310 übernimmt, und andererseits als Anschlag und Dreharretierung 314 der zur Kupplung 308 gehörenden Einklinktelle 313. Die freie Drehbarkeit des Lautsprecherkörpers 305 gegenüber dem Grundkörper 301 ergibt sich daraus, dass der Kupplungsteil 308 fest mit dem Grundkörper 301 verbunden ist, und die auf der gegenüberliegenden Seite angeordneten federnden Einklinkteile 313 in die Büchse 309 eingeschoben werden, dort dann widerhakenmässig arretiert sind, wobei diese Arretierungen den vorgegebenen Drehwinkei bestimmen, der immer einen genügenden Spielraum offen lässt, so dass selbst aussergewöhnliche Veränderungen der Kopfhaltung beim Benutzer immer aufgefangen werden können. Die hier durch die beschriebene Einklinktechnik vorgeschlagene Drehbarkeit zwischen Grundkörper 301 und Lautsprecherkörper 305 weist auf eine einfache Konstruktion hin, die uneingeschränkt eingesetzt werden kann und sie lässt auf jeden Fall zu, dass alle Körper- und Kopfhaltungen aufgefangen werden können. Sowohl Büchse 309 als auch Kupplungsteil 308 weisen eine Bohrung 312 auf, durch welche die elektrische Anschlussleitung 311 bis zum Lautsprecher 310 durchgeführt werden kann. Fig. 5 shows in a sectional plane the structure of such a small speaker after the Fig. 3a-3c , As already mentioned above, the coupling part 308 takes over the connection between the base body 301 and the loudspeaker body 305, this in turn being supplemented with a bushing 309, which on the one hand takes over the bearing of the loudspeaker 310, and on the other hand as an abutment and rotational locking 314 of the latching points belonging to the coupling 308 313. The free rotation of the speaker body 305 relative to the main body 301 results from the fact that the coupling member 308 is fixedly connected to the base 301, and arranged on the opposite side resilient latch members 313 are inserted into the sleeve 309, then barbed arrested there , These locks determine the predetermined Drehwinkei, which always leaves a sufficient margin open, so that even extraordinary changes in head posture can always be absorbed by the user. The ones here by the As described latching technique proposed rotation between the body 301 and speaker body 305 indicates a simple construction that can be used without restriction and it allows in any case that all body and head postures can be collected. Both sleeve 309 and coupling part 308 have a bore 312, through which the electrical connection line 311 can be performed to the speaker 310.

Fig. 6-8 zeigen die konstruktive Ausgestaltung des Kleinlautsprechers 400 gemäss Fig. 4a-4c, wobei hier die akustischen Oeffnungen 402 und die akustischen Tonöffnungen 407 in den grossen Flächen des linsenförmigen Lautsprecherkörpers 405 angeordnet sind. Der wesentliche Unterschied dieses Kleinlautsprechers 400 gegenüber dem vorgehenden 300 besteht darin, dass es sich hier um einen Einsatz parallel oder quasi-parallel zum Gehörgang bei teilweisem offenem Gehörgang handelt. Der Aufbau dieses Kleinlautsprechers 400, was die Drehbarkeit 406 betrifft, ist weitgehend gleich wie beim vorangegangenen Kleinlautsprecher (300), d.h., auch hier wird mittels eines Kupplungsteils 411 mit einem Einklinkteil (analog 313) jene Drehbarkeit erzielt, weiche dem beschriebenen finalen Zweck dient Die äussere Geometrie dieses Kleinlautsprechers 400 ist freilich eine eigene und sie geht aus den Fig. 6-8 unmissverständlich hervor. Ein Schnappmechanismus 412/413 sorgt dafür, dass der Abdeckungsteil 409 eingeklinkt werden kann, und so eine kompakte abgerundete Geometrie ergibt, was sehr wichtig für ein einwandfreies Tragen des Lautsprecherkörpers im Ohr ist. Die übrigen Teile dieses Kleinlautsprechers 400 haben die gleiche Fupktionalität wie beim vorangegangenen Kleinlautsprecher (300). Auch hier muss grosser Wert auf die Drehbarkeit des linsenförmigen Lautsprecherkörpers (405) im Ohr bei jeder Veränderung der Kopfsteilung gelegt werden, denn die Ankopplung im Ohrkanal ist hier nicht eine vollständig abschliessende, so dass kleinste übertragene Verschiebungen eine überproportionale Herabminderung der Tonqualität nach sich ziehen, abgesehen davon, dass solche Verdrehungen unangenehme Druckstellen zur Folge haben Fig. 6-8 show the structural design of the small speaker 400 according Fig. 4a-4c Here, the acoustic openings 402 and the acoustic sound openings 407 are arranged in the large areas of the lenticular loudspeaker body 405. The main difference of this miniature loudspeaker 400 from the previous 300 is that it is an insert parallel or quasi-parallel to the ear canal with a partially open auditory canal. The structure of this miniature speaker 400, which relates to the rotation 406, is largely the same as in the previous miniature speaker (300), ie, here by means of a coupling part 411 with a Einklinkteil (analog 313) achieved that rotation, which serves the described final purpose The outer geometry of this small speaker 400 is of course its own and it goes out of the Fig. 6-8 unmistakable. A snap mechanism 412/413 ensures that the cover portion 409 can be latched to give a compact rounded geometry, which is very important for proper support of the speaker body in the ear. The remaining parts of this mini speaker 400 have the same functionality as the previous mini speaker (300). Again, great importance must be placed on the rotatability of the lenticular loudspeaker body (405) in the ear with each change in the head pitch, because the coupling in the ear canal is not a completely final, so that the smallest transmitted shifts cause a disproportionate reduction in sound quality, Apart from the fact that such distortions have unpleasant pressure points result

Bel Kopfhörern, bei welchen das Passstück die ganze Ohrmuschel umschliesst, lässt sich ebenfalls eine in der Zeichnung nicht näher gezeigte Drehbarkeit nach denselben bereits beschriebenen Kriterien vorsehen, so dass der oder die Tragbügel dann beliebig am Kopf getragen werden können.Bel headphones, in which the fitting surrounds the entire auricle, also reveals a rotation not shown in the drawing provide the same criteria already described, so that the or the support bracket can then be worn arbitrarily on the head.

Anstelle der beschriebenen elektrischen Anschlussleitungen 311, 414 lässt sich zur Tonübertragung im Bereich der drehbaren Teile eine Verbindung mittels Schteifringkontakte vorsehen, welche dann die elektrische Verbindung zwischen den bewegilchen Lautsprecherkörpern 305, 405 und den jeweiligen Grundkörpern 301, 401 sicherstellen.Instead of the described electrical connection lines 311, 414, a connection by means of Schteifringkontakte can be provided for sound transmission in the region of the rotatable parts, which then ensure the electrical connection between the portable loudspeaker bodies 305, 405 and the respective basic bodies 301, 401.

Durch den Einbau einer in der Zeichnung nicht näher gezeigten Torsionsfeder am geeigneten Ort wird sichergesteilt, dass bei Nichtmehrbenutzung des Kopfhörers die Lage der Lautsprecherkörper 305, 405 gegenüber den Grundkörpern 301, 401 jene ursprüngliche Ruhesteilung wieder einnimmtBy installing a torsion spring not shown in the drawing at the appropriate location is sichergesteilt that when not using the headphone, the position of the speaker body 305, 405 against the main bodies 301, 401 that original rest division resumes
