Abstract (en)

[origin: EP1077583A2] The loudspeaker box has a housing (2) and at least one loudspeaker (4) with a chassis (6) enclosed by a housing wall (8) so that a rear and front sound in the low frequency range is superimposed with a sound increases in a predefined direction. The housing wall is mounted inside the housing to cause a sound increase at the front and a decrease at the rear. Independent claims are also included for a use of the loudspeaker box in a motor vehicle, esp. in a headrest and for a headrest with several integrated loudspeaker boxes.
