Description
Die vorliegende Erfindung betrifft einen Kopfhörer bzw. einen Gehörschutz.The The present invention relates to a headphone or a Ear protection.
Kopfhörer bzw. Headsets mit einer aktiven Lärmkompensation, welche beispielsweise auf einer Feedback-Regelungstechnologie beruht, sind hinlänglich bekannt.headphone or headsets with an active noise compensation, which For example, based on a feedback control technology are well known.
Da die menschliche Ohrmuschel bei jedem Menschen individuell ausgestaltet ist, sind die Reflexionen am Ohr bei jedem Menschen anders. Durch das Aus gleichselement kann somit eine definierte Schallreflexion für das Mikrofon vorgesehen werden.There the human auricle is designed individually for each human is, the reflections on the ear are different in each person. By the From the same element can thus a defined sound reflection for the microphone will be provided.
Bei derartigen Kopfhörern mit aktiver Lärmkompensation bzw. Störschallkompensation kann die Regelschleife für die aktive Lärmkompensation unter bestimmten Bedingungen jedoch instabil werden und sich aufschwingen. Dies kann insbesondere dann auftreten, wenn das Ohr oder Teile des Ohrs ein sehr kleines Volumen bilden, wobei sich sowohl das Mikrofon als auch der Wiedergabewandler in diesem kleinen Volumen befinden.at such headphones with active noise compensation or Störschallkompensation, the control loop for the active noise compensation under certain conditions but become unstable and swing up. This can be special then occur when the ear or parts of the ear is a very small one Make volume, with both the microphone and the playback converter located in this small volume.
Es ist somit eine Aufgabe der vorliegenden Erfindung, einen Kopfhörer bzw. ein Headset oder einen Gehörschutz vorzusehen, welcher Instabilitäten bei der aktiven Lärmkompensation zumindest verringert.It Thus, it is an object of the present invention to provide a headphone or provide a headset or hearing protection, which Instabilities in the active noise compensation at least reduced.
Diese Aufgabe wird durch einen Kopfhörer gemäß Anspruch 1 gelöst.These Task is by a headphone according to claim 1 solved.
Somit wird ein Kopfhörer mit einem elektroakustischen Wiedergabewandler, einem Mikrofon zur Aufzeichnung von Störschall und mit einer aktiven Lärmkompensationseinheit zum Kompensieren von Lärm basierend auf dem durch das Mikrofon aufgezeichneten Störschall vorgesehen. Der Kopfhörer weist ferner ein Gehäuse zur Aufnahme des Mikrofons und des elektroakustischen Wiedergabewandlers auf. Das Gehäuse weist ferner einen ersten Gehäuseabschnitt auf, welcher zumindest das Mikrofon derart umschließt, dass ein definiertes akustisches Volumen erhalten wird.Consequently becomes a headphone with an electro-acoustic reproduction transducer, a microphone for recording of background noise and with an active noise compensation unit for compensation from noise based on that recorded by the microphone Noise provided. The headphone also points a housing for receiving the microphone and the electro-acoustic Playback converter on. The housing further has a first housing section, which at least the microphone in such a way encloses that receive a defined acoustic volume becomes.
Die Erfindung beruht auf dem Gedanken, ein akustisches Volumen in einem Gehäuse eines Kopfhörers vorzusehen, welches durch den Benutzer bzw. durch die Körpergeometrie des Benutzers nicht verändert werden kann. Zusammen mit dem Regelungsmikrofon, dem Schallwiedergabewandler und der Elektronik für die aktive Lärmkompensation kann somit ein stabiles Regelungssystem gebildet werden. Das definierte akustische Volumen kann durch definierte Löcher an das Ohrvolumen angebunden werden. Ferner kann eine Stoffgaze auf den das akustische Volumen abgrenzenden Abschnitt aufgebracht werden.The Invention is based on the idea of an acoustic volume in one Housing a headphone to provide, which by the user or by the body geometry of the user can not be changed. Together with the control microphone, the sound reproduction converter and the electronics for the Active noise compensation can thus be a stable control system be formed. The defined acoustic volume can be defined by Holes are tied to the ear volume. Furthermore, can a fabric gauze on the acoustic volume delimiting section be applied.
Somit kann ein definiertes akustisches Volumen um das Regelungsmikrofon herum ausgebildet werden, um ggf. auftretende Instabilitäten sowie ein Rückkopplungspfeifen zu vermeiden.Consequently can define a defined acoustic volume around the control microphone be formed around, possibly occurring instabilities and to avoid feedback whistling.
Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further Embodiments of the invention are the subject of the dependent claims.
Die Vorteile und Ausführungsbeispiele der Erfindung werden nachstehend unter Bezugnahme auf die Zeichnung näher erläutert.The Advantages and embodiments of the invention will be explained in more detail below with reference to the drawing.

Gemäß einem weiteren Ausführungsbeispiel wird ein Headset basierend auf dem oben beschriebenen Kopfhörer vorgesehen. Dazu muss lediglich ein weiteres Mikrofon zur Aufzeichnung von Sprachsignalen vorgesehen werden.According to one Another embodiment is based on a headset provided on the headphones described above. This must be just another microphone for recording voice signals be provided.
