Abstract

PURPOSE:To make transmission characteristics and phase characteristics variable by automatically moving a tweeter and squawker box in the forward, backward and perpendicular direction as well as in the rotating direction of axial center by the use of power such as motor or the like in a speaker system. CONSTITUTION:A squawker box 2 is stacked under a tweetr box 1 and a woofer box 3 thereunder, with the acoustic centers of the respective speaker boxes being aligned. These are then respectively independently driven in the forward and backward directions, perpendicular direction and further rotating direction by driving a forward-backward moving motor 4, a rotation driving motor 10 and a motor 14, whereby the transmission characteristics and phase characteristics of the speaker system are made variable.
