In order to produce a powerful bass, bass boxes require a relatively large installation volume, for which insufficient space is frequently available in the interior of a motor vehicle, in particular in a passenger motor vehicle. When drivers and front-seat passengers require the sound installation to have a powerful bass, a bass box requires a volume in the order of magnitude of at least 10 to 15 liters. In order to restrict the physical space which is required for this purpose in the vehicle interior, the active sound transducer of the loudspeaker system is acoustically coupled on its rear face to a resonant area which is formed at least in parts by the cavity within a supporting structure of the vehicle. In this case, the sound transducer is acoustically coupled in the area surrounding an area of the vehicle in which at least two elements of the supporting structure meet one another, such that at least a portion of the resonant area is jointly formed by the cavities in these at least two elements of the supporting structure.

Loudspeaker system for motor vehicles utilizing cavities formed by supporting structures

An audio system for a motor vehicle includes a plurality of speaker units to which audio signals from various audio signal sources are supplied. The supply between at least one audio signal source and at least one speaker unit is at least partially redundant, including a primary supply and a secondary supply.

Audio system for an automobile

A vehicle audio system has an audio central unit to which one or more further audio components are connected via an associated first data bus, and are interfaced for data communication between the first data bus and a second data bus of another type in the vehicle. One of the audio components is an audio gateway unit which contains the interface, and is an independent component separate from the audio central unit. In addition to the data bus gateway functions, the audio gateway unit includes further standard audio functions spanning vehicle types or countries, or further audio functions which are implemented so as to be parameterizable according to specific vehicle type and/or country.

Vehicle audio system

An audio system, in particular for motor vehicles, having a loudspeaker installation for supplying sound to an audio chamber and a control unit with a signal detection unit for receiving microphone signals from at least one microphone exposed to the audio chamber outputting the signal to an evaluation unit which extracts interference signals from the microphone signals. The control unit produces control signals on the basis of these interference signals in order to operate the loudspeaker installation. To reduce the complexity for installation of such an audio system, at least one tweeter is connected in the loudspeaker installation as a microphone.
