<p>Disclosed is a loudspeaker system with a high degree of versatility and capable of appropriate responses even when a microphone or a person speaking moves. Multiple linked terminals (2) are connected to a central control device (1). A lecturer operates the central control device (1) to designate whether each linked terminal (2) functions as a speaker or a microphone. Because it is possible to designate from the central control device (1) which linked terminal (2) functions as a microphone or functions as a speaker, the lecturer can switch the positions and the number of microphones and speakers with one touch, according to the situation during the lecture-for example, when the lecturer is lecturing, or a questioner is asking a question, or the master of ceremonies is commenting. For example, there is no need for an assistant to go to the trouble of taking a microphone over to the questioner, and the system can respond appropriately to the state of movement of the person speaking, and the versatility and convenience is extremely high.</p> |
