Abstract: A microphone assembly for an external surface of a vehicle comprises a microphone housing, a microphone assembly, and a wind break member. The microphone housing comprises a housing support. The microphone is disposed in the microphone housing. The wind break member has a base and a wind break portion. The base of the wind break member comprises a floor surface, a leading edge, and a trailing edge opposite the leading edge. The wind break portion of the wind break member is disposed proximate the leading edge of the base. The microphone housing is disposed on the base of the wind break member proximate the wind break portion. The wind break portion comprises a top surface that forms a first angle relative to the base of the wind break member. The top surface has one of a concave shape, a convex shape, and a compound concave and convex shape.

Abstract: A microphone assembly includes a base that includes a first surface, a second surface and a third surface. The first surface is configured to connect the base to a mounting location in an external environment. The second surface is positioned parallel to the first surface with the third surface positioned therebetween. The third surface defines a curved shape to direct air flow that contacts the third surface in a direction away from the first surface. The microphone assembly also includes a cap disposed over and separated from the base by a gap. The cap includes a domed portion that has a convex shape that curves away from the second surface of the base. The microphone assembly also includes a microphone array that includes a plurality of microphones. The microphone array is disposed within the cap and is configured to receive acoustic signals from the external environment through the gap.

Abstract: A microphone assembly includes a housing including at least one first tube in communication with at least one first cavity, at least one second tube in communication with at least one second cavity, one third tube in communication with at least one third cavity, and at least one microphone element separating the first, second and third cavities, wherein sound waves are received in the first, second, and third tubes and directed into the cavities and received by the microphone element. A method for converting sound waves into an electrical signal includes receiving the sound waves through at least three tube openings and directing the received sound waves along tube pathways into at least a first, second, and third cavity to a microphone separating the first, second, and third cavity. The method further includes converting the received sound waves into an electrical signal with the microphone.

Abstract: A wind break device for a microphone includes an airflow diverter and a flow separation edge partially bordering a microphone end of the airflow diverter. The microphone zone located between the flow separation edge and is part of the recirculation zone. The microphone is located in the microphone zone. Airflow separates from one of the airflow diverter or the flow separation edge. The separated airflow is directed as one of recirculating airflow or a major airflow and the recirculating airflow is directed into the recirculation zone. The major airflow is directed over the microphone zone and the recirculation zone to reduce the level of pressure fluctuations experienced by the microphone in the microphone zone.

Abstract: A wind protection device for a microphone, the wind protection device including a body portion having a raised surface, a lower surface and a front face. The raised surface has a flow separation edge. The lower surface is offset from the raised surface the front face is bordered at a first edge by the flow separation edge and bordered at a second edge by the lower surface. The lower surface includes a recessed microphone holding area. Airflow separates from one of the raised surface or the flow separation edge, and the separated airflow is directed as one of recirculating airflow or a major airflow. The recirculating airflow is directed into a recirculation zone, and the major airflow is directed over a microphone zone and the recirculation zone to reduce the level of pressure fluctuations experienced by the microphone located in the recessed microphone holding area.

Abstract: An airflow guard for a microphone includes a shell having an airflow diverter and a flow separation edge. The airflow diverter partially surrounds the microphone to redirect a flow of air away from the microphone. The flow of air separates from one of the airflow diverter or the flow separation edge. An acoustic reception system for a mobile vehicle and a hands-free communication device are also disclosed.
