Abstract
Description
Mikrophon microphone
Die Erfindung betrifft ein Mikrophon und insbesondere eine Halterung für eine Mikrophonkapsel .The invention relates to a microphone and in particular to a holder for a microphone capsule.
Eine Lautsprecherhalterung ist aus der US 4,633,972 bekannt. Es wird dabei der Lautsprecher mittels einer elastischen, spinnenartigen Halterung gegen das Paneel eines Kraftfahrzeuges gedrückt. Die Stöße und Vibrationen des Fahrzeuges werden dabei dem Lautsprecher aufgeprägt. Für ein Mikrophon ist daher eine solche Halterung völlig ungeeignet :A speaker bracket is known from US 4,633,972. The loudspeaker is pressed against the panel of a motor vehicle by means of an elastic, spider-like holder. The shocks and vibrations of the vehicle are impressed on the loudspeaker. Such a holder is therefore completely unsuitable for a microphone:
Bei Mikrophonen ist es wichtig, daß die die schallaufneh- menden Teile enthaltende Mikrophonkapsel, im folgenden kurz Kapsel genannt, gegenüber mechanischen Schwingungen, Vibrationen und Stößen aus der Umgebung abgekoppelt ist, da es sonst zu Überlagerungen dieser Störsignale mit den akustischen Signalen kommt. Dieses Gebot der Abkopplung wird im Bereich der Mikrophone, die fest eingebaut werden, insbesondere dann wichtig, wenn das Mikrophon als Teil einer Freisprechanlage für ein Mobiltelefon od.dgl. in einem Fahrzeug eingebaut ist.In the case of microphones, it is important that the microphone capsule containing the sound-absorbing parts, hereinafter referred to as the capsule, is decoupled from mechanical vibrations, vibrations and impacts from the environment, since otherwise these interference signals are superimposed on the acoustic signals. This requirement of decoupling is important in the field of microphones that are permanently installed, especially when the microphone or the like is part of a hands-free system for a mobile phone. is installed in a vehicle.
Bisher wurden Kapseln derartiger Mikrophone zwischen Lagen von Schaumstoff- oder Gummimaterial gelagert, um sie gegen die mechanischen Einflüssse abzuschirmen. Dies führt aber nicht zu den gewünschten Ergebnissen und so sind fest eingebaute Mikrophone von Freisprecheinrichtungen in Fahr- zeugen nach wie vor wesentlich stärker mit Fremdgeräuschen überlagert als vergleichbare Mikrophone, die in der Hand gehalten werden.So far, capsules of such microphones have been stored between layers of foam or rubber material in order to shield them from mechanical influences. However, this does not lead to the desired results and so built-in microphones from hands-free systems in vehicles are still much more overlaid with external noise than comparable microphones that are held in the hand.
Dazu kommt, daß diese Lagerung zusätzliche Löcher in der Verkleidung, in der die Mikrophone eingebaut werden, benötigt, um die in den Kapseln üblicherweise vorgesehene hintere Schalleintrittsöffnung, die zur Erzielung der Richtcharakteristik notwendig sind, beschallen zu können. Es ist aus der GB 1 599 545 A und der GB 1 599 546 A weiters bekannt, die Membrane eines Lautsprechers vom Laut- sprechergehäuse dadurch schwingungstechnisch abzukoppeln, daß ein Befestigungsmaterial mit kleiner Hysterese verwendet wird. Für die Kopplungsproblematik einer Mikrophonkapsel ist daraus nichts abzuleiten.In addition, this storage requires additional holes in the casing, in which the microphones are installed, in order to be able to sonicate the rear sound inlet opening usually provided in the capsules, which are necessary to achieve the directional characteristic. It is also known from GB 1 599 545 A and GB 1 599 546 A to decouple the diaphragm of a loudspeaker from the loudspeaker housing in terms of vibration technology by using a fastening material with a small hysteresis. Nothing can be deduced from this for the coupling problem of a microphone capsule.
Die Erfindung bezweckt Abhilfe zu schaffen und eine Kap- sellagerung anzugeben, durch die die Kapsel eines solchen Mikrophons zuverlässig und über weite Frequenzbereiche, auch bei relativ großen Amplituden mechanischer Schwingungen, von diesen abgekoppelt bleibt und zumindest in einer Ausgestaltung eine einfachere Beschallung der hinteren Schalleintrittsöffnung der Kapsel erlaubt.The object of the invention is to remedy this and to provide a capsule mounting by means of which the capsule of such a microphone remains decoupled reliably and over wide frequency ranges, even with relatively large amplitudes of mechanical vibrations, and at least in one embodiment a simpler sound system for the rear sound inlet opening Capsule allowed.
Erfindungsgemäß ist dazu vorgesehen, die Kapsel in einer Halterung aus gummielastischem Material zu lagern, wobei die Halterung zumindest drei, bevorzugt im wesentlichen in einer Ebene verlaufenden, Armen versehen ist, die im Abstand von der Halterung, bevorzugt an ihren freien Enden, Verdickungen aufweisen, die in passend ausgebildeten Ausnehmungen des Mikrophongehäuses einsteckbar sind.According to the invention, the capsule is provided in a holder made of rubber-elastic material, the holder being provided with at least three arms, preferably running essentially in one plane, which have thickenings at a distance from the holder, preferably at their free ends, which can be inserted into appropriately designed recesses in the microphone housing.
Auf diese Weise wird die Kapsel schwebend aufgehängt gelagert, wobei durch die relativ kleinen Querschnitte der Arme die Beanspruchung zufolge von Vibrationen und Erschütterungen des Einbauteils und damit des Mikrophongehäuses in den Armen konzentriert wird und dort zu relativ starken Deformationen führt, die durch das gummielastische Material einerseits ertragen werden können, andererseits durch dessen stark schwingungsdämpfende Eigenschaften rasch und zuverlässig gedämpft werden.In this way, the capsule is suspended and suspended, whereby due to the relatively small cross-sections of the arms, the stress due to vibrations and shocks of the built-in component and thus of the microphone housing is concentrated in the arms and there leads to relatively strong deformations caused by the rubber-elastic material on the one hand can be endured, on the other hand can be damped quickly and reliably due to its strong vibration-damping properties.
In einer Ausgestaltung der Erfindung ist vorgesehen, daß die Arme im wesentlichen sternförmig verlaufen. Damit kann eine gleichmäßige Aufnahme und Abarbeitung von Erschütte- rungen und Vibrationen unabhängig von ihrer Richtung erzielt werden.In one embodiment of the invention it is provided that the arms run essentially in a star shape. This enables a uniform recording and processing of vibrations vibrations can be achieved regardless of their direction.
In einer weiteren Ausgestaltung ist vorgesehen, daß der Querschnitt der einzelnen Arme im wesentlichen kreisförmig ist oder die Form eines regelmäßigen Polygons (Quadrat) aufweist. Damit kann eine weitere Vereinheitlichung der Schwingungs- und Dämpfungseigenschaften erzielt werden.In a further embodiment it is provided that the cross section of the individual arms is essentially circular or has the shape of a regular polygon (square). A further standardization of the vibration and damping properties can thus be achieved.
In einer vorteilhaften Weiterbildung ist vorgesehen, daß die Arme im eingebauten Zustand der Halterung und Kapsel im wesentlichen deformationsfrei und damit ohne statische Grundlast sind.In an advantageous development it is provided that the arms in the installed state of the holder and capsule are essentially free of deformation and thus without a static base load.
Die Erfindung wird im folgenden an Hand eines Beispieles näher erläutert . Dabei zeigt die Fig. 1 einen Axialschnitt durch ein Mikophongehäuse samt Halterung, die Fig. 2 eine Draufsicht auf das Gehäuse nach Fig. 1 mit abgenommenem Deckel, die Fig. 3 einen Schnitt entlang der Linie III -III der Fig. 2 und die Fig. 4 eine Draufsicht auf eine erfindungsgemäße Halterung .The invention is explained in more detail below using an example. 1 shows an axial section through a microphone housing including the holder, FIG. 2 shows a plan view of the housing according to FIG. 1 with the cover removed, FIG. 3 shows a section along the line III-III of FIG. 2 and FIG 4 shows a plan view of a holder according to the invention.
Wie aus Fig. 1 ersichtlich, ist in einem Bauteil 1, beispielsweise einem Armaturenbrett eines Kraftfahrzeuges, ein in seiner Gesamtheit mit 2 bezeichnetes Mikrophon eingebaut. Im wesentlichen besteht dieses Mikrophon aus einem Gehäuse 3, einem Deckel 4, einer Halterung 5 und einerAs can be seen from FIG. 1, a microphone, designated in its entirety by 2, is installed in a component 1, for example a dashboard of a motor vehicle. This microphone essentially consists of a housing 3, a cover 4, a holder 5 and one
Kapsel 13 samt Printplatte 14 eines Vorverstärkers.Capsule 13 including printed circuit board 14 of a preamplifier.
Aus Fig. 2, die eine Draufsicht bei abgenommenem Deckel 4 auf das Gehäuse 3 und die Halterung 5 zeigt, ist ersieht - lieh, daß das Gehäuse 3 einen Kabelzufuhrkanal 6 aufweist und in seinem Inneren eine im wesentlichen rechteckige Ausnehmung 7, in der die Halterung 5 aus gummielastischem Material montiert ist. Wie aus Fig. 2 und 3 ersichtlich ist, ist die Halterung 5 auf allen Seiten mit Abstand vom Gehäuse 3 bzw. dem Deckel 4 angeordnet und mit dem Gehäuse 3 nur mittels vier Armen 8 verbunden. Die Arme 8 tragen an ihren Enden Verdickungen 9, die in Ausnehmungen 10 des Gehäuses 3 in Richtung normal zur Zeichenebene einschiebbar sind und durch den Deckel 4 gegen ein Herausgleiten gesichert sind.From Fig. 2, which shows a top view with the cover 4 removed on the housing 3 and the holder 5, it can be seen - loaned that the housing 3 has a cable feed channel 6 and in its interior a substantially rectangular recess 7 in which the holder 5 is assembled from rubber-elastic material. As can be seen from FIGS. 2 and 3, the holder 5 is arranged on all sides at a distance from the housing 3 or the cover 4 and is connected to the housing 3 only by means of four arms 8. The arms 8 carry thickenings 9 at their ends, which can be inserted into the recesses 10 of the housing 3 in the direction normal to the plane of the drawing and are secured against sliding out by the cover 4.
Im dargestellten Ausführungsbeispiel sind vier Arme vorgesehen, die jeweils im wesentlichen im rechten Winkel von länglichen, nahezu rechteckigen Körper der Halterung 5 abstehen. Dies ist, wie oben ausgeführt, nicht notwendig, es kann bevorzugt auch eine sternförmige Anordnung der Arme 8 vorgesehen sein, dies richtet sich einerseits nach den räumlichen, andererseits nach den dynamischen Gegebenheiten, an die die erfindungsgemäße Halterung anzupassen ist .In the exemplary embodiment shown, four arms are provided, each of which projects essentially at right angles from the elongated, almost rectangular body of the holder 5. As stated above, this is not necessary; a star-shaped arrangement of the arms 8 can preferably also be provided, this depends on the one hand on the spatial, on the other hand on the dynamic conditions to which the holder according to the invention is to be adapted.
In Fig. 4 ist die erfindungsgemäße Halterung 5 in einer Draufsicht, wie in Fig. 2 aber ohne Gehäuse 3 dargestellt. Ein durchgehendes Loch 11 dient als Einsatz für die Kapsel 13. Diese weist zur Erzielung einer Richtcharakteristik einen hinteren Schalleintritt auf. Ein Schlitz 12 erlaubt den ungehinderten Schallzutritt zum hinteren Schalleintritt der Kapsel 13, wodurch diese ihre vorgegebene Richtcharakteristik beibehält.4 shows the holder 5 according to the invention in a top view, as shown in FIG. 2 but without the housing 3. A through hole 11 serves as an insert for the capsule 13. This has a rear sound inlet in order to achieve a directional characteristic. A slot 12 allows unimpeded sound access to the rear sound entry of the capsule 13, whereby it maintains its predetermined directional characteristic.
Der Schlitz 12 weist an seinem gehäusebodenseitigen Ende seiner kapselfernen Wand eine Schulter 15 auf, durch die die Schallführung weiter verbessert wird.The slot 12 has a shoulder 15 on its housing-side end of its wall remote from the capsule, through which the sound guidance is further improved.
Die Abmessungen und Positionen der Arme 8 und der Verstärkungen 9 sind vorzugsweise so gewählt, daß sie praktisch ohne Deformation der Arme 8 in die Ausnehmungen 10 des Gehäuses 3 eingeschoben werden können, mit anderen Worten, die Halterung 5 ist im eingesetzten, betriebsbereiten Zustand ohne Vorspannung der Arme 8 gelagert, diese tragen nur das gegenüber den dynamischen Kräften unbedeutende Gewicht der Halterung samt Kapsel.The dimensions and positions of the arms 8 and the reinforcements 9 are preferably selected so that they can be inserted into the recesses 10 of the housing 3 practically without deformation of the arms 8, in other words, the holder 5 is in the inserted, ready-to-use state without pretension the arms 8 stored, wear them only the insignificant weight of the holder including the capsule compared to the dynamic forces.
Im gezeigten Ausführungsbeispiel deckt der Deckel 4 die Einstecköffnungen der Ausnehmungen 10 beim Aufsetzen ab, es wird auf diese Weise eine einfache Montage der Halterung und Sicherung der Arme möglich.In the exemplary embodiment shown, the cover 4 covers the insertion openings of the recesses 10 when it is put on, in this way simple mounting of the holder and securing of the arms is possible.
Die Erfindung ist nicht auf das dargestellte Ausführungs- beispiel beschränkt, sondern kann verschiedentlich abgewandelt werden. So ist es möglich, die Halterung und damit die Kapsel schräg im Gehäuse anzuordnen, um die Kapsel, die ja üblicherweise eine vorgegebene Richtcharakteristik aufweist, im Hinblick auf den vorgesehenen Einsatz ent- sprechend zu montieren.The invention is not limited to the exemplary embodiment shown, but can be modified in various ways. It is thus possible to arrange the holder and thus the capsule at an angle in the housing, in order to mount the capsule, which usually has a predetermined directional characteristic, with regard to the intended use.
Die Halterung 5 muß nicht aus gummielastischem MaterialThe bracket 5 does not have to be made of rubber-elastic material
(entropieelastischem) im engen Sinne eines Naturkautschuks oder Kautschuks sein, sondern kann auch aus einem anderen elastischen und bevorzugt eine hohe Eigendämpfung gegenüber Deformationen aufweisenden Material, beispielsweise Weichkunststoffen od.dgl. gebildet sein. Das Vorhandensein der Dämpfung trägt dazu bei, die Ausbildung einer scharfen Eigenfrequenz des schwingungsf higen Systems zu vermeiden, was der Qualität der Lagerung und damit der Übertragung weiter zu gute kommt .(Entropy-elastic) in the narrow sense of a natural rubber or rubber, but can also be made from another elastic and preferably have a high internal damping against deformation material, for example soft plastics or the like. be educated. The presence of the damping helps to avoid the formation of a sharp natural frequency of the vibratory system, which further benefits the quality of the bearing and thus the transmission.
Es ist selbverständlich möglich, die Arme anders als formschlüssig am Gehäuse zu befestigen, dies kann z.Bsp. auch durch Verkleben, Ultraschallschweißen oder Aufvulkanisie- ren geschehen.It is of course possible to attach the arms to the housing other than in a form-fitting manner. also done by gluing, ultrasonic welding or vulcanization.
Der Ausdruck "relativ kleiner Querschnitt der Arme" ist anhand der Größe der Halterung zu beurteilen, ebenso der Ausdruck "biegeweich", der sich auf die zu erwartenden dynamischen, nicht auf die nur geringen statischen mechanischen Kräfte bezieht. The expression "relatively small cross-section of the arms" is to be assessed on the basis of the size of the holder, as is the expression "flexible", which relates to the expected dynamic, not the only small, static mechanical forces.
