PURPOSE:To realize a loudspeaker cabinet which is light and highly rigid, by using a composite material which is obtained by placing a balsa material so as to intersect of which fiber direction the surface material at right angles between surface materials made of plastic or fiber reinforced plastic. CONSTITUTION:A loudspeaker cabinet is constituted of a composite material 6 which is obtained by placing a balsa material 4 between two surface materials 3, 3 consisting of plastic or fiber reinforced plastic, so as to intersect of which fiber direction the surface materials 3 and 3 at right angles. |
