发明名称 LOUDSPEAKER DIRECTIVITY CONTROL METHOD AND AUDIO REPRODUCTION DEVICE
摘要 To provide an audio reproduction apparatus in which a general user inputs simple and easy settings so that audio beams of respective channels can be set. When an array speaker is installed in a room, the user inputs the shape of the room into the audio reproduction apparatus. Based on the shape of the room, the audio reproduction apparatus determines a beam control pattern indicating which directions audio signals of the channels should be formed respectively. The audio reproduction apparatus reads beam control data including delay times for forming the beams in the directions from a pattern memory, and automatically sets the beam control data in a DSP. Thus, only when the user inputs the shape of the room, the beams are controlled with a beam control pattern suitable to the room so that multi-channel audio can be reproduced optimally.
