Abstract: A system for transmitting an audio signal in a vehicle includes a stabilizer located at a source position in the vehicle. At least one speaker is operatively connected to the stabilizer. The speaker is adapted to transmit an audio signal to a target position for at least partially supporting a spatial audio representation. The target position and the source position are independently movable. The stabilizer is adapted to direct the audio signal such that a trajectory between the target position and the source position is maintained regardless of respective motion of the target position and the source position. The trajectory includes a first segment between the source position and a deflecting surface and a second segment between the deflecting surface and the target position.
