LOUDSPEAKER BOX IN THE SHAPE OF A SHELL CONSTRUCTION

摘要

A loudspeaker box designed as a shell construction, where the outer and inner peripheral surfaces of the box are made of reinforced plastic and are preferably twin-curved with a continuously varying radius of curvature, where the distance between the outer and the inner shell is not constant and where the space between the shells is filled with a light material with good adhesion to the shells, preferably foam plastic. This design principle is intended to avoid natural resonances while at the same time ensuring low weight and high strength.
