Abstract:
A speaker box and a speaker device that can be manufactured at low cost and that provide a sound-absorbing effect. A speaker box of a speaker device includes a baffle, four intermediate plates, and a rear plate. The baffle plate has a speaker mount hole at the center. Each intermediate plate has a hole. The intermediate plates are stacked such that they are alternately reversed or rotated so that the holes in the adjacent intermediate plates communicate with each other while the holes are shifted from with each other. A hollow space with a sound-absorbing effect is formed by the holes in the speaker box.
