摘要： PROBLEM TO BE SOLVED: To make large contact area between the gas absorvent and surrounding space thereof regardless of a cabinet shape, in a speaker instrument for improving low-pitched sound reproducing performance with gas adsorvent.
SOLUTION: The speaker instrument includes a speaker unit, a cabinet, gas adsorvent, and spherical elastic body. The cabinet is formed with a space at a rearside of the speaker unit. The spherical elastic body is placed in the space with the gas adsorvents enclosed therein. This makes it possible easily to increase the contact area of the gas adsorvent and the surrounding space thereof, even if the cabinet is in a complex shape.
