Abstract

PURPOSE:To sufficiently absorb low sounds and eliminate such troubles that sounds are made unclear and a loudspeaker cabinet vibrates, by wrapping grains such as sand, shaping the wrapped grains as a thick cusion and lining the cabinet with the cushion. CONSTITUTION:Grains such as sand are wrapped. The wrapped grains 2 are vertically and horizontally placed and mounted on a base 1 so that a vibration preventer 3 like a thick cushion is formed. The vibration preventer is bonded on the inside of a loudspeaker cabinet 4 to prevent it from vibrating. Since the wrapped grains 2 have no elasticity, sound energy is absorbed by plastic deformation. As a result, the cabinet 4 is prevented from vibrating, sounds in the cabinet are absorbed and other sounds are prevented from being made unclear.
