Patent

CA 2387125

A microphone assembly (1700) includes one or more transducers (1702) positioned in a housing (1732). Circuitry (Fig. 8) is coupled to the transducer for outputting an electrical signal such that the microphone has a main lobe directed forwardly and attenuates signals originating from the sides and/or rear. The transducers can advantageously include multiple transducers, which, with the circuit, produce a desired sensitivity pattern. The microphone assembly can be employed in a vehicle accessory.

Le dispositif de microphone (1700) comprend au moins un transducteur (1702) placé dans un boîtier (1732). Des circuits (fig. 8) sont couplés au transducteur pour produire un signal électrique de telle manière que le microphone présente un lobe principal dirigé vers l'avant et atténue des signaux provenant des côtés et/ou de l'arrière. Les transducteurs peuvent, de manière avantageuse, comprendre plusieurs transducteurs, qui, avec le circuit, produisent un motif de sensibilité souhaité. Le dispositif de microphone peut être utilisé dans un accessoire de véhicule.
