Audio system arranged in a listening environment
An audio system arranged in a listening environment in a vehicle comprises at least one multimedia unit configured to output an audio signal, and at least one display loudspeaker, wherein each of the at least one display loudspeaker is coupled to the at least one multimedia unit and receives the audio signal from the at least one multimedia unit, and each of the at least one display loudspeaker comprises an OLED panel and at least one exciter coupled to the OLED panel and configured to vibrate the OLED panel to reproduce the audio signal.
1 . An audio system arranged in a listening environment in a vehicle comprises at least one multimedia unit configured to output an audio signal,
one or more reference microphones arranged in a cabin of the vehicle,
at least one display loudspeaker, wherein
each of the at least one display loudspeaker is coupled to the at least one multimedia unit and receives the audio signal from the at least one multimedia unit,
each of the at least one display loudspeaker comprises an OLED panel and at least one exciter coupled to the OLED panel and configured to vibrate the OLED panel to reproduce the audio signal, and
each of the at least one display loudspeakers is arranged in front of a respective passenger of the vehicle such that the sound emitted from the display loudspeaker is directed toward the respective passenger from a same direction as engine noise entering the cabin of the vehicle from a front of the vehicle, and
a control unit configured to receive reference signals from the one or more reference microphones, the reference signals being indicative of engine sound present in the vehicle cabin, wherein the control unit, based on the reference signals, generates anti-noise components having a phase opposite to a phase of the engine sound, and the anti-noise components are output by the at least one display loudspeaker.
2 . The audio system of claim 1 , wherein at least one of:
one display loudspeaker is arranged in front of a driver seat of the vehicle,
one display loudspeaker is arranged in front of a front passenger seat of the vehicle,
one display loudspeaker is arranged at the back of the driver seat and in front of a first rear passenger seat, and
one display loudspeaker is arranged at the back of the front passenger seat and in front of a second rear passenger seat.
3 . The audio system of claim 1 , wherein each of the at least one display loudspeaker comprises two exciter coupled to the respective OLED panel.
4 . The audio system of claim 1 , wherein
the at least one multimedia unit is further configured to output a video signal, and
each of the at least one display loudspeaker is configured to output the video signal on the OLED panel.
5 . The audio system of claim 4 , wherein the audio signal represents an audio track corresponding to the video signal.
6 . The audio system of claim 1 , further comprising at least one additional loudspeaker coupled to the at least one multimedia unit.
7 . The audio system of claim 6 , wherein the at least one additional loudspeaker comprises at least one of:
one or more front passenger speakers,
one or more rear passenger speakers,
one or more subwoofers, and
one or more tweeters.
8 . The audio system of claim 1 , wherein the sound emitted by each of the at least one display loudspeaker comprises planar sound waves directed toward the respective passenger seated in front of the display loudspeaker, such that the anti-noise components output by each display loudspeaker are directed toward the respective passenger and are not received as direct sound by other passengers in the vehicle cabin.
9 . The audio system of claim 1 , wherein the vehicle is a passenger car, a van, a camper van, a caravan, a truck, a bus, a tractor, an airplane, or a ship.
