Abstract:
1. An array speaker system comprising a plurality of line array units each including a plurality of speaker units aligned on a straight line at equal intervals with a spacing between the speaker units in a longitudinal direction of the line array unit, the line array units being linked in a lateral direction perpendicular to the longitudinal direction, the line array units being offset in the longitudinal direction by “the spacing/the number of the line array units linked in the lateral direction”, each of the line array units further comprising: a case in which the plurality of speaker units are disposed, the case having longitudinal side faces in the longitudinal direction and lateral side faces in the lateral direction; a plurality of linking connectors, at least one linking connector being disposed on each of the lateral side faces and at least two linking connectors being disposed on each of the longitudinal side faces; an input device for inputting audio signals; a signal processing device for supplying the audio signals by delaying them at specific delay times to each speaker unit and for controlling a directivity of the line array unit; a link detection device for detecting a linked direction and a linked position of the line array unit within the array speaker system based on a connection state of the plurality of linking connectors; and a control device for setting delay times of the signal processing device according to the linked direction and the linked position detected by the link detection device.
