1. Loudspeaker system for a vehicle, comprising:
- a loudspeaker array comprising a plurality of electroacoustic sound transducers that can be controlled individually, such that a user-specific audio signal can be reproduced for different users at different listening positions in a vehicle interior via the plurality of electroacoustic sound transducers,wherein the loudspeaker array is arranged in a roof lining of the vehicle, centrally between at least all listening positions in the vehicle interior, such that a distance between the loudspeaker array and all of the listening positions is the same, with a deviation of +/−
30%,wherein the loudspeaker system comprises, per listening position, at least one additional loudspeaker system comprising at least one additional loudspeaker or an additional loudspeaker array,wherein the additional loudspeaker system comprises a structure-borne sound loudspeaker that is arranged in a foot space allocated to the listening position, in a seat allocated to the listening position and/or a headrest allocated to the listening position and/or that is mechanically coupled to the seat allocated to the listening position;
wherein the loudspeaker system is configured to perform, with the help of the plurality of the electroacoustic sound transducers of the loudspeaker array, acoustic beamforming for forming the beams;
wherein middle and higher frequencies are reproduced in a directed manner for the different listening positions by means of the array, while the low frequencies are only represented locally via the structure-bound sound transducer.

Abstract
A loudspeaker system for a vehicle includes a loudspeaker array including a plurality of electroacoustic sound transducers that can be controlled individually, such that a user-specific audio signal can be reproduced for different users at different listening positions in a vehicle interior of the vehicle via the plurality of electroacoustic sound transducers. Here, the loudspeaker array or a sound outlet of the loudspeaker array is arranged in particular between at least two of the listening positions in the vehicle interior, i.e. for example between the driver and the passenger seat.
