Description
Die vorliegende Erfindung betrifft einen Kopfhörer sowie eine Hörsprechgarnitur.The present invention relates to a headphone and a headset.
Die Verwendung von aktiven Geräuschkompensationseinheiten bei Kopfhörern sind beispielsweise durch die Sennheiser-Kopfhörer HDC 451, PXC 250 und HMEC 25 bekannt. Der Störschall bzw. die Umgebungsgeräusche werden durch ein Mikrofon erfasst und der aktiven Störschallkompensationseinheit zugeführt, wodurch dieser Störschall derart kompensiert wird, dass der Störschall lediglich leise wahrgenommen wird. Anwendung für derartige geräuschkompensierte Kopfhörer sind im Cockpit eines Flugzeuges zur Unterdrückung des Fluglärmes sowie privat einsetzbare Kopfhörer zur Unterdrückung des Fluglärmes in einer Passagierkabine bekannt. Ferner können Headsets mit einer derartigen Geräuschkompensation ebenfalls im Auto vorgesehen werden, um möglichst störungsarm in dem Auto telefonieren zu können.The use of active noise cancellation units in headphones is known, for example, from the Sennheiser HDC 451, PXC 250 and HMEC 25 headphones. The background noise or ambient noise is detected by a microphone and fed to the active noise cancellation unit, whereby this background noise is compensated in such a way that the background noise is perceived only quietly. Application for such noise-compensated headphones are known in the cockpit of an aircraft to suppress aircraft noise and privately usable headphones for suppressing the aircraft noise in a passenger cabin. Furthermore, headsets with such a noise compensation can also be provided in the car in order to be able to make calls in the car with as little interference as possible.
Üblicherweise werden derartige geräuschkompensierte Kopfhörer über einen üblichen Kopfhöreranschluss angeschlossen, über den das zu übertragene Au-Audiosignal eingegeben wird. Dieses Audio- bzw. Fremdsignal kann beispielsweise ein Unterhaltungsprogramm oder Musik an Bord eines Flugzeuges oder ein Telefonsignal darstellen. Dieses Audiosignal wird über den in der Geräuschkompensationseinheit befindlichen Verstärker eingespeist, entsprechend verstärkt und zusammen mit den Signalen der Geräuschkompensationseinheit ausgegeben.Usually, such noise-compensated headphones are connected via a conventional headphone jack, via which the Au audio signal to be transmitted is entered. This audio or external signal can represent, for example, an entertainment program or music on board an aircraft or a telephone signal. This audio signal is fed in via the amplifier located in the noise compensation unit, amplified accordingly and output together with the signals of the noise compensation unit.
Bekannt sind ferner Hörsprechgarnituren bzw. Headsets, welche neben dem Kopfhörer auch ein Sprachmikrofon bzw. ein Boommikrofon aufweisen. Eine Stromversorgung erfolgt entweder durch einen zusätzlichen Anschluss oder durch eine Batterieversorgung. Die aktive Geräuschkompensationseinheit ist hierbei mit dem Kopfhörer verbunden.Also known are headsets or headsets, which in addition to the headphones also have a voice microphone or a boom microphone. A power supply is provided either by an additional connection or by a battery supply. The active noise compensation unit is connected to the headphones.
Abgesehen von diesen Fällen, bei denen eine tatsächliche bidirektionale Kommunikation ermöglicht sein soll, sind auch Anwendungen vorhanden, bei denen die Geräuschkompensation im Vordergrund steht. Beispiele dazu sind der Industrielärmschutz, und ein Hören von Musik in einer lärmerfüllten Umgebung wie beispielsweise in Zügen oder beim Rasen mähen.Apart from these cases, where an actual bi-directional communication is to be enabled, there are also applications in which the noise compensation is in the foreground. Examples include industrial noise protection, and listening to music in a noisy environment such as trains or lawn mowing.
Es ist somit Aufgabe der vorliegenden Erfindung, eine Hörsprechgarnitur mit aktiver Geräuschkompensation vorzusehen, wobei ein Übermitteln bzw. Wiedergeben von Audiosignalen verbessert wird.It is therefore an object of the present invention to provide a headset with active noise compensation, wherein a transmission or reproduction of audio signals is improved.
Diese Aufgabe wird durch eine Hörsprechgarnitur gemäß Anspruch 1 gelöst.This object is achieved by a headset according to claim 1.
Somit wird eine Hörsprechgarnitur mit einem Mikrofon und einer aktiven Störschallkompensationseinheit zur Kompensation von Störschall vorgesehen. Zusätzlich dazu weist der Kopfhörer einen drahtlosen Empfänger zum drahtlosen Empfangen eines wiederzugebenen Audiosignals auf. Sowohl die aktive Störschallkompensationseinheit als auch der drahtlose Empfänger sind in demselben Gehäuse in oder an der Hörsprechgarnitur untergebracht. Die Hörsprechgarnitur weist ebenfalls einen Informationsspeicher zum Speichern und Wiedergeben von Audiosignalen auf, wobei der Informationsspeicher mindestens einen Wiedergabewandler zum Wiedergeben der gespeicherten Audiosignale oder der durch den Drahtlosempfänger empfangenen Audiosignale aufweist. Der Informationsspeicher ist dazu ausgestaltet, die Wiedergabe aus dem Informationsspeicher anzuhalten, wenn der Drahtlosempfänger eine Nachricht empfängt.Thus, a headset is provided with a microphone and an active noise cancellation unit to compensate for background noise. In addition to this, points the headset includes a wireless receiver for wirelessly receiving an audio signal to be reproduced. Both the active noise cancellation unit and the wireless receiver are housed in the same housing in or on the headset. The headset also has an information storage for storing and reproducing audio signals, the information storage having at least one reproduction converter for reproducing the stored audio signals or the audio signals received by the wireless receiver. The information store is configured to stop playback from the information store when the wireless receiver receives a message.
Durch das Vorsehen des drahtlosen Empfängers, können Informationen bzw. Audiosignale gerichtet bzw. absichtlich an den Träger des Kopfhörers weitergeleitet werden, ohne dass diese Signale von der Störschallkompensationseinheit wegkompensiert werden.By providing the wireless receiver, information or audio signals can be intentionally forwarded to the wearer of the headset without these signals being compensated away by the noise canceling unit.
Die Erfindung beruht auf dem Gedanken, anstatt eines zusätzlichen Gerätes zum drahtlosen Empfangen von Audiosignalen den Empfänger in bzw. an dem Kopfhörer bzw. der Hörsprechgarnitur zu implementieren. Somit muss lediglich ein einzelnes Gerät für die aktive Störschallkompensation und für den drahtlosen Empfang vorgesehen werden, was den Tragekomfort erhöht.The invention is based on the idea of implementing the receiver in or on the headset instead of an additional device for wireless reception of audio signals. Thus, only a single device for active noise cancellation and for wireless reception must be provided, which increases the comfort.
Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further embodiments of the invention are the subject of the dependent claims.
Nachfolgend wird die Erfindung detailliert unter Bezugnahme auf die Zeichnungen beschrieben.

- zeigt eine schematische Ansicht eines Kopfhörers gemäß einem ersten Beispiel,
- Figur 2
- zeigt eine schematische Darstellung eines Kopfhörers gemäß einem zweiten Beispiel, und
- Figur 3
- zeigt eine schematische Darstellung einer Hörsprechgarnitur gemäß einem dritten Beispiel.
- FIG. 1

- FIG. 3
- shows a schematic representation of a headset according to a third example.
Eine für eine gute Sprachverständigung notwendige elektrische Entzerrung, d.h. eine Frequenzganganpassung, eine Dynamikregelung und eine Dynamikkompression des Signals des Ohrmikrofons (M) wird ebenfalls zusammen mit der aktiven Störschallkompensationseinheit (ASK) implementiert. Alternativ dazu kann die Entzerrungseinheit in dem Kopfhörer/Schallschutzkappengehäuse angeordnet sein. Mit einem derartigen Kopfhörer mit Ohrmikrofon kann der aktive Störschallkopfhörer zu einer bidirektionalen Kommunikation verwendet werden, d.h. eine Hörsprechgarnitur kann realisiert werden. Während bei herkömmlichen (Boom-)Mikrofonen eine gute Störschallaufbereitung nur dann möglich ist, wenn das Mikron in der Nähe am Mund getragen wird, um ein ausreichendes Signal, zum Geräuschverhältnis für die Gegenstelle zu implementieren, wird gemäß dem dritten Ausführungsbeispiel das Ohrmikrofon (M) verwendet, um die Sprache eines Anwenders in der Hörsprechgarnitur aufzuzeichnen. Durch die Verwendung des Ohrmikrofons wird ferner ein Problem des biologischen Feedbacks einer Person reduziert. Bei Personen, die geräuschkompensierte Kopfhörer tragen, kommt es vor, dass sie leiser sprechen, da sie sich subjektiv deutlich leiser wahrnehmen und somit keinen Grund haben lauter zu sprechen.An electrical equalization necessary for good speech intelligibility, i. Frequency response adjustment, dynamics control and dynamic compression of the ear microphone (M) signal are also implemented together with the Active Noise Compensation Unit (ASK). Alternatively, the equalization unit may be disposed in the headphone / noise enclosure housing. With such earphone microphone, the active noise canceler can be used for bidirectional communication, i. a headset can be realized. While in conventional (boom) microphones, a good noise treatment is only possible if the micron is worn close to the mouth in order to implement a sufficient signal to the noise ratio for the remote station, according to the third embodiment, the ear microphone (M) used to record the language of a user in the headset. The use of the ear microphone also reduces a problem of biological feedback from a person. People who wear noise-compensated headphones sometimes have a lower voice, since they perceive themselves to be significantly quieter and therefore have no reason to speak louder.
Alternativ zum oben Angeführten kann eine Hörsprechgarnitur auch mit einem Boommikrofon anstatt bzw. zusätzlich zum Ohrmikrofon vorgesehen werden.As an alternative to the above, a headset can also be provided with a boom microphone instead of or in addition to the ear microphone.
Der drahtlose Empfänger (I) gemäß dem ersten, zweiten und dritten Beispiel kann dabei drahtlos beispielsweise durch DECT-, durch Bluetooth- oder durch WLAN-Technologie realisiert werden. Alternativ dazu kann der Empfänger (I) ebenfalls als ein Rundfunkempfänger (FM/AM/DAB/DVB-T) implementiert werden. Ferner ist ein Funkübertragungsempfänger wie beispielsweise bei drahtlosen Kopfhörern möglich. Alternativ dazu ist ebenfalls ein Infrarot- oder ein Ultraschallempfänger möglich.The wireless receiver (I) according to the first, second and third examples can thereby be realized wirelessly, for example, by DECT, by Bluetooth or by WLAN technology. Alternatively, the receiver (I) may also be implemented as a radio receiver (FM / AM / DAB / DVB-T). Further, a radio transmission receiver such as wireless headphones is possible. Alternatively, an infrared or an ultrasonic receiver is also possible.

Such an information memory can be used as a semiconductor memory, as a semiconductor memory with a source reduction function (AAC, MP3, etc.), be designed as a magnetic tape memory or as opto-electronic memory.
Wenn sowohl der Informationsspeicher als auch der drahtlose Empfänger (I) zusammen implementiert werden, ist der Informationsspeicher derart ausgestaltet, dass die Wiedergabe aus dem Informationsspeicher angehalten wird, wenn der drahtlose Informationsempfänger eine Nachricht wie beispielsweise ein Telefonat, empfängt. Nach Ende dieser Nachricht kann die Wiedergabe der in dem Informationsspeicher gespeicherten Audiosignale wieder gestartet werden.When both the information storage and the wireless receiver (I) are implemented together, the information storage is configured to stop playback from the information storage when the wireless information receiver receives a message such as a telephone call. After the end of this message, the reproduction of the audio signals stored in the information memory can be restarted.
Durch die gemeinsame Implementation der aktiven Störschallkompensationseinheit und dem Informationsempfänger bzw. dem Informationsspeicherkönnen bestimmte Komponenten wie beispielsweise ein Vorverstärker, ein Endverstärker oder dgl. gemeinsam, d.h. sowohl für das Geräuschkompensationssignal als auch die Audiosignale von dem Informationsempfänger bzw. dem Informationsspeicher verwendet werden, so dass diese Komponenten nicht doppelt vorgesehen sein müssen. Ferner kann ein gemeinsamer Lautstärkeregler, eine gemeinsame Stromversorgung und/oder ein gemeinsames Gehäuse vorgesehen werden.Through the joint implementation of the active noise cancellation unit and the information receiver, certain components, such as a preamplifier, a power amplifier, or the like, may be common to each other. be used for both the noise compensation signal and the audio signals from the information receiver or the information store, so that these components need not be provided in duplicate.
