IN-CAR COMMUNICATION

摘要

An in-car communication system and method configured to pick up sound from the first passenger position with a first microphone arrangement in the vicinity of a first passenger position and to convert the picked-up sound into a first electrical microphone signal. The system and method are further configured to convert with a first loudspeaker arrangement in the vicinity of a second passenger position a first electrical loudspeaker signal into sound, to radiate the sound to the second passenger position, and to process the first electrical microphone signal to provide the first electrical loudspeaker signal. The first loudspeaker arrangement has a principal transmitting direction into which it radiates its maximum sound energy. The loudspeaker arrangement is disposed such that the radiated maximum sound energy is concentrated at the second passenger position.
