ABSTRACT:
A speaker cabinet in which a cross section of an outer peripheral portion (11) is formed as an elliptic shape and opening portions (22 to 25) formed on the outer peripheral portion (11) and into which speakers (2 to 5) are mounted are formed as horn shapes whose diameters are improved toward the outside. The speaker cabinet includes a plywood member (10) that is formed by laminating a hard plate member, a soft plate member and a light and soft rear surface plate member on a face front surface plate member. The cabinet is molded in a predetermined curved fashion to have an elliptic shape. Thus, an acoustic characteristic of the speaker cabinet can be increased and a manufacturing cost of the speaker cabinet can be reduced.
