Abstract

Die Erfindung betrifft eine Lautsprecheranordnung (1) zur gerichteten Beschallung eines Kraftfahrzeugsitzes (8) in einem Kraftfahrzeug, umfassend mindestens zwei Lautsprecher (4,5,6), die von mindestens einem Audio-Prozessor (2) ansteuerbar sind, wobei der erste Lautsprecher als mindestens ein elektrostatischer Flächenlautsprecher (4) ausgebildet ist und der mindestens eine zweite Lautsprecher (5,6) in der Kopfstütze (7) des zugeordneten Kraftfahrzeugsitzes (8) angeordnet ist, wobei das abzustrahlende Audio-Signal (9) in einen hochfrequenten Teil (10,11) und einen tieffrequenten Teil (12,13) zerlegt wird, wobei der elektrostatische Flächenlautsprecher (4) mit dem hochfrequenten Teil (10,11) angesteuert wird und der zweite Lautsprecher mit dem tieffrequenten Teil (12,13) angesteuert wird, wobei die Amplitude des tieffrequenten Teils (12,13) derart gewählt wird, dass die tieffrequenten Teile nicht als Schall abgestrahlt werden, und ein zugehöriges Verfahren.

The invention relates to a loudspeaker arrangement (1) for directional sounding of a motor vehicle seat (8) in a motor vehicle, comprising at least two loudspeakers (4,5,6) which can be controlled by at least one audio processor (2), wherein the first loudspeaker at least one electrostatic area loudspeaker (4) is formed and the at least one second loudspeaker (5, 6) is arranged in the headrest (7) of the associated motor vehicle seat (8), the audio signal (9) to be radiated into a high-frequency part (10 , 11) and a low-frequency part (12,13) is decomposed, wherein the electrostatic surface speaker (4) with the high-frequency part (10,11) is driven and the second speaker with the low-frequency part (12,13) is driven, the amplitude of the low-frequency part (12, 13) is chosen such that the low-frequency parts are not emitted as sound, and an associated method.
