Abstract
A microphone assembly includes at one or more transducers positioned in a housing. Circuitry 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. The microphone transducers can advantageously include multiple transducers which with the circuit produce a desired sensitivity pattern. The microphone can be employed in a vehicle accessory.
