<p>A speaker box and a speaker device that can be inexpensively produced and having a sound absorption effect. A speaker box (12) of a speaker device (10) has a baffle (14), four intermediate plates (16, 16, ...), and a back side plate (18). A speaker installation hole (14a) is formed in the center of the baffle plate (14). Each intermediate plate (16) has a hole (16a). The intermediate plates (16, 16, ...) are superposed on each other with the front and back sides of every other plate reversed so that adjacent holes (16a, 16a) are communicated with each other with their positions displaced from each other. A cavity having a sound absorption effect is formed inside the speaker box (12) by the holes (16a, 16a, ...).</p> |
