Loudspeaker system for motor vehicles utilizing cavities formed by supporting structures

Abstract

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.
