AN AUTOMATIC CONTROL SYSTEM FOR SOUND OF CLUSTER SPEAKER

摘要

PURPOSE: An automatic control system for the sound of a cluster speaker is provided to prevent the deterioration due to the interference between unit speakers by controlling the direction of the speaker cluster. CONSTITUTION: A plurality of unit speakers(110) are installed on the inner side of a speaker cluster(100). The speaker clusters are connected with each other through at least main cable(210) and a location shift cable(230). The main cable and the location shift cable are connected to a driving mechanism(250) which is installed on grid zinc(270). The driving mechanism simultaneously drives the location shift cable and the main cable. The driving mechanism comprises a drive motor(251), a reducer(253), and a drum(255).
