Low-frequency range loudspeaker housing

摘要

The housing has a front wall (1), a back wall (2) and a side wall (4,4') connecting the front and back walls. At least one of the walls has at least one audio outlet opening. The side wall is divided into two sections along a plane running parallel to the front and back walls. The cross-sections of the two sections are of different sizes such that the section of the side wall connected to the back wall can be moved into or on to the section connected to the front wall. Preferably the section of the side wall connected to the back wall has a smaller cross-section than that connected to the front wall and may have a seal (7,8) around its outer side which lies on the inner side of the section connected to the front wall. Alternatively, if the cross-section of the section connected to the from wall may be smaller than that connected to the back wall and may have a seal around its outside which lies on the inner side of the section connected to the back wall.
