PROBLEM TO BE SOLVED: To eliminate the need for high machining accuracy and an increase in the number of assembling steps in a speaker box, the need arising because the end of a side plate requires a complicated fitting structure and a complicated reinforcement is internally necessary in preventing vibrations around a driver mounting hole owing to the operation of the diaphragm of a driver, preventing outer resonance, and obtaining airtightness in a part requiring airtightness in an internal space. SOLUTION: Side plates (31) and (32) are supported by a support (8) with radially extended arms (1) to (3). COPYRIGHT: (C)2009,JPO&INPIT
