Abstract

The hearing aid has the miniature loudspeaker normally employed replaced by a number of electroacoustic transducers embedded in the moulded plastics of the hearing aid module which fits within or behind the ear. The electroacoustic transducers may be provided using a multi-layer foil structure and are operated adjacent their resonance range, with a fuzzy logic used for matching to the rest of the hearing range.

Description

Aufgabe eines Hörgerätes ist es, den Schalldruckpegel von Sprache und allen anderen gewünschten akustischen Signalen in den Hörbereich von Hörbehinderten zu verla gern, also so zu verstärken, daß er zwischen der individuellen Hör- und Unbehaglich keitsschwelle liegt. Task of a hearing aid is to verla like, so to enhance the sound pressure level of language and all other desired acoustic signals in the audible range of hearing impaired so that it lies between the individual hearing and Uncomfortable keitsschwelle.

Prinzipiell werden auf dem Markt drei Hörgerätebauarten angeboten: In principle, three types hearing aids available on the market:
1. Taschenhörgeräte 2. "Hinter dem Ohr"-Hörgeräte und 3. "In dem Ohr"-Hörgeräte. 1. pocket hearing aid 2. "Behind the ear" hearing aids and 3. "In the ear" hearing aids. Während sich die Taschenhörgeräte durch hohe Verstärkungen und gute akustische Eigenschaften auszeichnen, nimmt der Marktanteil dieser Geräte infolge geringer Komfortabilität und aus ästhetischen Gründen permanent ab. During his pocket Hearing aids are characterized by high gains and good acoustic properties, the market share of these devices due to low comfortableness and for aesthetic reasons decreases permanently. Die "Hinter-" und "In dem Ohr"-Hörgeräte sind infolge des geringeren Abstandes zwischen Mikrofon und Minia turlautsprecher bezüglich der akustischen Verstärkung begrenzt. The "rear" and "In-the-ear" hearing aids of the acoustic gain are due to the smaller distance between the microphone and Minia turlautsprecher regard is limited. (Bei Hörgeräteakusti kern werden diese Miniaturlautsprecher einfach als Hörer und hier in der Patentbe schreibung zukünftig als elektroakustische Wandler bezeichnet). (This miniature speakers are nuclear In Hörgeräteakusti write-future as electroacoustic transducers simply as listeners and here in the Patentbe called). Das geringe Batterie volumen macht elektroakustische Wandler mit großem Wirkungsgrad erforderlich, was aber auf Kosten der Übertragungsqualität geht, so daß diese Hörgeräte häufig nur als Unterstützung zum Lippenlesen betrachtet werden können. The volume of low battery makes electro-acoustic transducer with high efficiency is required, but this comes at the expense of the quality of transmission, so that these hearing aids can often be regarded as support for lip-reading. Alle elektroakustischen Wandler der "Hinter-" und "In dem Ohr"-Hörgeräte (Klasse-A, Klasse-B und Klasse-D) werden durch "Peek-Clipper" oder "Automatic Gain Control" bezüglich des Ausgangs schalldruckes begrenzt, was energetisch vorteilhaft ist, aber zu großen Verzerrungen führt. All electro-acoustic transducers of the "rear" and "In-the-ear" hearing aids (class-A, class-B and class-D) with respect to the output sound pressure is limited by "Peek-Clipper" or "Automatic Gain Control", which energetically is advantageous, but leads to large distortions.

Der Erfindung liegt Aufgabe zu Grunde, "Hinter-" und "In dem Ohr"-Hörgeräte mit we sentlich besserem akustischen Verhalten und geringem Stromverbrauch zu entwickeln. The invention is object of "rear" and "In the ear" hearing aids with we develop sentlich better acoustic performance and low power consumption.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß anstelle eines Miniaturlaut sprechers mehrere gleiche und/oder unterschiedliche elektroakustische Wandler ver wendet und in der Otoplastik integriert werden. The object is inventively achieved in that speaker uses a plurality of identical and / or different electro-acoustic transducer ver instead of a miniature sound and be integrated in the ear device. Ähnlich wie bei Lautsprecherboxen ist mit mehreren Schallquellen ein wesentlich besseres Klangbild erreichbar, als wenn nur ein einzelner elektroakustischer Wandler verwendet wird. Similar to Loudspeakers a much better sound image can be achieved than if only a single electro-acoustic transducer is used with a plurality of sound sources.

Durch die Kombination dieses aus mehreren elektroakustischen Wandlern bestehen den Wiedergabesystems mit einer auf der Fuzzy Logik basierenden Ansteuerung kön ne die sonst üblichen Frequenzweichen und Filter eingespart und die elektroakusti schen Wandler nahe ihrer Resonanzfrequenz betrieben werden, was einen extrem niedrigen Stromverbrauch zur Folge hat. By combining this pass the reproducing system of a plurality of electro-acoustic transducers with a based on the fuzzy logic control Kgs ne the usual crossovers and filter saved and the elektroakusti rule transducers are operated close to its resonance frequency, which has an extremely low power consumption.

Mit einem sogenannten "Neuro-Fuzzy-Input-Gain-Control" können Frequenzgang und Schalldruck an den individuellen Hörverlust optimal angepaßt und gleichzeitig Ferti gungsabweichungen der elektroakustischen Wandler ausgeglichen werden. With a so-called "neuro-fuzzy input gain-control" can be adapted optimally frequency response and acoustic pressure at the individual hearing loss and at the same pro duction deviations of the electro-acoustic transducer are compensated.

Dank neuentwickelter mikrotechnischer Verfahren wie z. Thanks to newly developed micro-technical methods such. B. der LIGA-Technik sind aku stische Wandlersysteme in der benötigten Größe kostengünstig herstellbar. As the LIGA technique are aku STIC conversion systems manufactured cost of the required size.

Fig. 1 zeigt ein Ausführungsbeispiel in der "Hinter dem Ohr"-Bauart. Fig. 1 shows an embodiment in the "behind the ear" type. Durch die Verle gung des Wandlersystems ( 1 ) aus dem Gehäuse ( 2 ) in das Ohrpaßstück ( 3 ) vergrößert sich der Abstand zwischen Mikrofon ( 4 ) und Schallquelle, was höhere Verstärkungen zuläßt; The distance between the microphone (4) and the sound source, which allows for higher gains by the Verle of the transducer system (1) supply from the housing (2) in the ear tip (3) increases; gleichzeitig verbessert sich die Knochenleitungsübertragung. at the same time, the bone conduction transmission improved. Desweiteren kön nen durch den Wegfall des Hörervolumens kleinere Gehäuse ( 1 ) oder zusätzliche Batterien verwendet werden. Furthermore, smaller housing (1) or additional batteries Kgs NEN be used by eliminating the handset volume.

Da das akustische Ausgangssignal nicht im Gehäuse, sondern im Ohrpaßstück erzeugt wird, entfällt der sonst übliche Kunststoffschlauch, der Tragekomfort und Akustik ver schlechtert. Since the acoustic output signal is not generated in the housing, but in the ear tip, the usual plastic tube, the wearing comfort and eliminates acoustic ver deteriorated. Statt dessen ist eine elektrische Verbindung ( 5 ) nötig, die aus höchstflexi blem Material oder als Ohrschmuck realisierbar ist. Instead, an electrical connection (5) is necessary, which can be realized from highly flexi problem material or as earrings.

Das Ohrpaßstück besteht aus der individuellen Außenform ( 6 ) und einem stets identi schen Kernstück ( 7 ), in welchem die elektroakustischen Wandler (I) - hier als Mehr schichtfolienlautsprecher auf Spiralband realisiert -, Dämpfungs- und Belüftungssy steme untergebracht sind. The ear tip is made of the individual outer mold (6) and an always identi rule core piece (7), in which the electro-acoustic transducer (I) - as a multi-layer film speaker realized here spiral belt -, damping and Belüftungssy stems are housed.
