Die Erfindung bezieht sich auf eine Mikrofonanordnung mit verstellbarer Richtcharakteristik für Kraftfahrzeuge, mit zumindest zwei MEMS(micro-electro-mechanical-systems)-Mikrofonkapseln, einer Windschutzeinrichtung, mittels der die zumindest zwei MEMS-Mikrofonkapseln gegen nicht akustische Windeinwirkungen schützbar sind, und einer elektronischen Steuervorrichtung mit einer Auswerteeinheit, die an die zumindest zwei MEMS-Mikrofonkapseln angeschlossen ist, und einer Steuereinheit, mittels der die Richtcharakteristik der Mikrofonanordnung verstellbar ist.The invention relates to a microphone array with adjustable directional characteristic for motor vehicles, with at least two MEMS (micro-electro-mechanical systems) microphone capsules, a windbreaker, by means of which the at least two MEMS microphone capsules are protected against non-acoustic wind effects, and an electronic Control device with an evaluation unit which is connected to the at least two MEMS microphone capsules, and a control unit, by means of which the directional characteristic of the microphone arrangement is adjustable.
Im Betrieb von Kraftfahrzeugen treten häufig störende Nebengeräusche auf, die z.B. auf Windeinwirkungen zurückgehen bzw. ihre Ursache in Windeinwirkungen haben.In the operation of motor vehicles disturbing background noises occur frequently, e.g. due to wind effects or their cause in wind effects.
Der Erfindung liegt die Aufgabe zugrunde, eine Mikrofonanordnung mit verstellbarer Richtcharakteristik zur Verfügung zu stellen, bei der ein optimales Tonsignal auch dann zur Verfügung gestellt werden kann, wenn störende Windeinwirkungen auftreten.The invention has for its object to provide a microphone array with adjustable directivity available, in which an optimal sound signal can also be made available when disturbing wind effects occur.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Windschutzeinrichtung für jede der zumindest zwei MEMS-Mikrofonkapseln zweiteilig aus einem ersten Windschutzelement und einem zweiten Windschutzelement ausgebildet ist, zwischen denen jeweils eine Schallkammer angeordnet ist, dass mittels der zumindest zwei von den MEMS-Mikrofonkapseln gemessenen akustischen Messsignale in der Auswerteeinheit der Mikrofonanordnung ein für Windrichtung und -intensität charakteristisches Windsignal errechenbar ist, und dass die Richtcharakteristik der Mikrofonanordnung mittels der Steuereinheit der elektronischen Steuervorrichtung in Abhängigkeit vom charakteristischen Windsignal einstellbar ist. Der Störeinfluss, der auf Windeinwirkungen zurückgeht, wird erfindungsgemäß minimiert. Mittels der beiden MEMS-Mikrofonkapseln, die Bestandteil der Mikrofonanordnung sind, kann eine jeweils optimale Ausrichtung der Mikrofonanordnung vorgenommen werden, wobei hierzu das von den beiden MEMS-Mikrofonkapseln stammende Messsignal in das charakteristische Windsignal umgerechnet wird, welches dann bei der Ver- bzw. Einstellung der Richtcharakteristik der Mikrofonanordnung berücksichtigt wird.This object is achieved in accordance with the invention in that the wind protection device for each of the at least two MEMS microphone capsules is formed in two parts from a first wind protection element and a second wind protection element, between each of which a sound chamber is arranged, that by means of the at least two measured by the MEMS microphone capsules acoustic Measuring signals in the evaluation of the microphone assembly is a wind direction and intensity characteristic wind signal can be calculated, and that the directional characteristic of the microphone assembly by means of the control unit of the electronic control device in response to the characteristic wind signal is adjustable. The interference caused by wind effects is minimized according to the invention. By means of the two MEMS microphone capsules, which are part of the microphone arrangement, a respective optimal alignment of the microphone arrangement can be made, for which purpose the measuring signal originating from the two MEMS microphone capsules is converted into the characteristic wind signal, which is then used during the adjustment or adjustment the directional characteristic of the microphone arrangement is taken into account.

Das erste Windschutzelement und das zweite Windschutzelement der Windschutzeinrichtung der erfindungsgemäßen Mikrofonanordnung sind vorteilhaft aus unterschiedlichen Textilgeweben ausgebildet. Im Zusammenwirken mit den Schallkammern und dem ersten und dem zweiten Windschutzelement wird hierbei die Windenergie signifikant abgebaut, ohne dass die Akustik störend beeinflusst wird.The first wind protection element and the second wind protection element of the wind protection device of the microphone arrangement according to the invention are advantageously formed of different textile fabrics.

Accordingly, the second windbreaker can also function as a screen. The microphone arrangement according to the invention can advantageously be designed as a cylinder microphone.
Beim Betrieb der erfindungsgemäßen Mikrofonanordnung wird der Wind hinsichtlich seiner Stärke und seiner Richtung detektiert. Das erfasste Resultat wird dazu verwendet, um die Richtcharakteristik des Nutzsignals der Mikrofonanordnung über die Steuereinheit der elektronischen Steuervorrichtung zu steuern, bis hin zu einem omnidirektionalen Charakter bei starkem Wind. Hierdurch kann die Windbeeinflussung der erfindungsgemäßen Mikrofonanordnung erheblich reduziert werden.During operation of the microphone arrangement according to the invention, the wind is detected in terms of its strength and its direction. The detected result is used to control the directional characteristic of the useful signal of the microphone arrangement via the control unit of the electronic control device, up to an omnidirectional character in strong wind. As a result, the wind influence of the microphone arrangement according to the invention can be significantly reduced.
