Abstract
A driver unit is fixed to a stand. A front box and a rear box are directly fitted to the stand through a buffer material. A box comes into contact with the driver unit through a buffer material and is fixed to the stand. Therefore, sound of the driver unit is not transmitted to the box and the drop of sound quality of the speaker can be prevented. The driver unit is fixed to the stand at an immovable foundation, and sound energy can be efficiently transmitted from a speaker cone to the air.
