Abstract
Description
Die vorliegende Erfindung betrifft einen Hörer, insbesondere einen In-Ear Hörer.The The present invention relates to a handset, in particular an in-ear Handset.
Wenn der Gehörgang eines Menschen beispielsweise durch einen In-Ear Hörer, durch eine Otoplastik oder dergleichen verschlossen wird, dann kann Schall nicht mehr ungehindert zum Trommelfell übertragen werden. Andererseits kann körpereigener Schall, d. h. Körperschall, durch den verschlossenen Gehörgang nicht abgestrahlt werden, so dass die eigene Sprache, Schluck- und Kaugeräusche sowie das Atmen als deutlich lauter wahrgenommen wird. Dieser Effekt wird als sogenannter Okklusionseffekt bezeichnet. Durch den Okklusionseffekt wird der durch den Schädelknochen weitergeleitete Schall als unangenehm und dumpf empfunden. Dadurch, dass der Gehörgang verschlossen ist, kann es ferner nicht mehr zu einem Druckausgleich kommen.If the auditory canal of a human, for example, through an in-ear listener, through an earmold or the like is closed, then sound can no longer be transferred unhindered to the eardrum. on the other hand can be the body's own sound, d. H. Structure-borne sound, through the closed ear canal not be blasted, so that your own language, and swallowing chewing sounds as well as the breathing is perceived as significantly louder. This effect is called a so-called occlusion effect. By the occlusion effect gets through the skull bone passed on sound as unpleasant and dull felt. Thereby, that the ear canal is closed, it can also no longer to a pressure equalization come.
Um einen entsprechenden Druckausgleich zu ermöglichen, werden In-Ear Hörer typischerweise mit einer Belüftungsbohrung vorgesehen, so dass Luft durch diese Belüftungsbohrung sowohl ein- als auch austreten kann.Around To enable a corresponding pressure equalization, in-ear listeners are typically with a ventilation hole provided so that air through this ventilation hole both on and off can escape.
Es ist somit Aufgabe der vorliegenden Erfindung, einen In-Ear Hörer vorzusehen, durch welchen der Okklusionseffekt zumindest teilweise behoben werden kann.It It is therefore an object of the present invention to provide an in-ear receiver, which at least partially corrects the occlusion effect can.
Diese Aufgabe wird durch einen In-Ear Hörer gemäß Anspruch 1 gelöst.These The object is achieved by an in-ear receiver according to claim 1.
Die vorliegende Erfindung betrifft den Gedanken, den Okklusionseffekt, welcher dadurch auftritt, dass der Gehörgang beispielsweise durch ein Ohranpassstück verschlossen wird, zu reduzieren. Dazu wird in dem Ohranpassstück ein Mikrofon und ein elektroakustischer Wandler vorgesehen. Der Schallwandler wird dabei derart angesteuert, dass in dem Gehörgang auftretende Schallwellen nicht reflektiert sondern absorbiert werden. Somit kann ein Schallpegel innerhalb des Gehörgangs sowie an dem Trommelfell reduziert werden. Akustisch betrachtet handelt es sich somit um eine Anpassung der Abschlussimpedanz am Gehöreingang bzw. im Gehörgang.The The present invention relates to the idea of the occlusion effect, which occurs because the ear canal, for example, by an ear fitting is closed, reduce. For this purpose, a microphone is in the Ohranpassstück and an electroacoustic transducer is provided. The sound transducer is controlled in such a way that occurring in the ear canal sound waves not reflected but absorbed. Thus, a sound level inside the ear canal and reduced to the eardrum. Acoustically considered it is therefore an adaptation of the terminating impedance on auditory input or in the ear canal.
Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further Embodiments of the invention are the subject of the dependent claims.
Ausführungsbeispiele und Vorteile der Erfindung werden nachstehend unter Bezugnahme auf die Zeichnung näher erläutert.embodiments and advantages of the invention will be described below with reference to FIGS Drawing closer explained.
Das Ohranpassstück O bzw. der In-Ear Hörer ist dabei derart ausgestaltet, dass der Eingang des Gehörgangs G (dicht) verschlossen wird, so dass sich ein abgeschlossenes Volumen durch den Gehörgang G, das Trommelfell T und das Ohranpassstück O ausbildet. In diesem Volumen ist ein gewisser Schalldruck p vorhanden, da das Ohranpassstück O keine Belüftungsbohrung, d. h. keine durchgehende Verbindung zwischen dem ohrseitigen Ende und der Außenseite des Hörers, aufweist.The Ohranpassstück O or the in-ear listener is designed such that the entrance of the ear canal G (tightly) is closed, leaving a closed volume through the ear canal G, the eardrum T and the Ohranpassstück O trains. In this volume there is a certain sound pressure p, since the Ohranpassstück O no Vent hole, d. H. no continuous connection between the ear-end and the outside the listener, having.
Das Ohranpassstück kann beispielsweise Schaum aufweisen. Das Ohranpassstück kann ferner eine Elektronikeinheit bzw. Kompensationseinheit KE zur Verarbeitung der durch den Schallaufnehmer M aufgezeichneten Signale und zum Steuern des Betriebs des Schallwandlers W aufweisen.The Ohranpassstück may for example have foam. The ear fitting can Furthermore, an electronic unit or compensation unit KE for processing the recorded by the transducer M signals and the Control the operation of the transducer W have.
Die durch den Schallaufnehmer M aufgezeichneten Signale innerhalb des Gehörgangs werden einer Kompensationseinheit KE zugeführt, welche die aufgezeichneten Signale von den wiederzugebenden Audiosignale subtrahiert und das entsprechende Ergebnis an den Schallwandler W ausgibt, um den Schalldruck im Gehörgang zu reduzieren und ggf. Schallwellen im Gehörgang G zu absorbieren.The signals recorded by the sound pickup M within the meatus are supplied to a compensation unit KE, which records the recorded Subtracts signals from the audio signals to be reproduced and the corresponding result to the transducer W outputs to the sound pressure in the ear canal to reduce and possibly absorb sound waves in the ear canal G.
Der elektroakustische Schallwandler W ist in dem In-Ear Hörer derart angeordnet, dass er den erzeugten Schall in Richtung des Gehörganges bzw. in Richtung des ohrseitigen Endes abgibt, wenn der In-Ear Hörer sich in dem Gehörgang befindet und der elektroakustische Schallwandler W entsprechend betrieben wird. Der Schallwandler strahlt somit den Schall in den Gehörgang ab, ohne dass ein Volumen vor dem Wandler in dem Gehäuse des In-Ear Hörers vorhanden ist.Of the electro-acoustic sound transducer W is in the in-ear listener such arranged that he generated the sound in the direction of the auditory canal or in the direction of the ear-end, when the in-ear listener in the ear canal is located and the electro-acoustic transducer W accordingly is operated. The transducer thus radiates the sound in the ear canal without a volume in front of the transducer in the housing of the In-ear listener available is.
Der oben beschriebene In-Ear Hörer weist vorzugsweise keine Belüftungsbohrung auf.Of the above-described in-ear listener preferably has no vent hole on.
Der Schallaufnehmer M und der Schallwandler W können ebenfalls als ein kombiniertes Aktor-Sensorsystem implementiert werden.Of the Sound pickup M and the transducer W can also be used as a combined Actuator sensor system can be implemented.
