PURPOSE:To raise a vibration suppressing property of a loudspeaker cabinet by laminating a vibration suppressing material on a loudspeaker cabinet base material, and laminating a restriction material on said material. CONSTITUTION:A loudspeaker cabinet is assembled to a box type by a cabinet base material (a lauan plywood) 1. A sheet-like vibration suppressing material 2 is stuck to the inside of five surfaces except a loudspeaker installing surface. Also, an iron sheet 3 is stuck as a restriction material onto the vibration suppressing material 2. As for the base material, wood, thermoplastic resin, thermosetting resin, metal, high elastic fiber reinforced plastic, resin concrete, etc. are used. As for the vibration suppressing material, that which has a large loss against vibration, such as rubber, thermoplastic resin, thermosetting resin, etc. is used. As for the restriction material, an iron sheet, an aluminum sheet, a wooden plate, etc. are used. Also, a plate to which a network is installed can be used as the restriction material, as well. |
