Loudspeaker e.g. woofer, box for e.g. automobile, has subspaces formed for support structure by two of three units e.g. sill, cross beam and chassis beam, and sound transducer integrated in area, at which two units strike on each other

摘要

The box has an active sound transducer (10) attached at a support structure of a motor vehicle and positioned such that subspaces, which are separated from each other, are attached at each of two diaphragm sides of the transducer. The subspaces are formed of three units such as sill (2), cross beam (3) and longitudinal chassis beam (4), of the structure by volumes of a hollow space. The subspaces are formed by two of the units of the support structure. The transducer is integrated in an area, in which the two units of the structure strike on each other.
