Bandpass box in the supporting structure of a vehicle
First Claim
1. A loudspeaker box in a vehicle having a supporting structure, comprisingat least one active sound transducer (10), including a diaphragm with first and second sides, fitted in the loudspeaker box,at least first and second subcompartments, wherein the sound transducer positioned such that the first and the second sides of its two sides of the diaphragm are adjoined respectively by one of the respective subcompartments which are isolated from one another and which are each formed by the volume of the cavity in at least one element (2, 3, 4) of the supporting structure of the vehicle (1), andat least one sound tunnel (11) between a subcompartment and the vehicle interior in which at least some of the sound waves produced in the subcompartments by the sound transducer (10) are introduced into the interior of the vehicle (1),wherein the subcompartments are formed by at least two elements (2, 3, 4) of the supporting structure of the vehicle (1), andwherein the sound transducer (10) is integrated in a region in which at least two elements (2, 3, 4) of the supporting structure meet one another.

Abstract
A sound system which has, for example, a radio, a cassette and a CD player is usually already installed in cars as standard or as an option. In addition, a better sound system includes a box system which has a tweeter and a woofer. In order to provide a speaker box which is suitable particularly for dispensing frequencies below 150 Hz and at the same time has neat pulses accompanied at the same time by little distortion, pulse dynamics and is highly effective, a sound transducer (10) is introduced into the supporting structure of the vehicle. This takes place in such a manner that subcompartments which are separated from each other adjoin each of its two membrane sides. In this case, the two subcompartments of the speaker box are formed by at least two elements (2, 3, 4) of the supporting structure of the vehicle (1). The sound transducer (10) is particularly integrated into a region in which two elements (2, 3, 4) of the supporting structure meet each other, thus resulting in an installation position which can be realized in a structurally and economically favorable manner.
