摘要： A sound field control unit includes a microphone collecting sound about a self-unit, a collected sound signal input-output terminal for outputting a collected sound signal of the self-unit to outside of the self-unit and inputting a collected sound signal of other units to the self-unit, a collected sound signal switch for switching the collected sound signal collected by the self-unit and that collected by the other units sequentially and repeatedly, an FIR filter for producing a reflected sound component of the collected sound signals provided by the switch and imparting it to the collected sound signals, an amplifier for amplifying the imparted reflected sound component and the collected sound signal, an equalizer provided in a signal path between an output terminal of the collected sound signal switch and an input terminal of the amplifier for adjusting frequency characteristic of a signal flowing through the signal path, and a loudspeaker for reproducing the amplified output signal. These components are assembled integrally together in the self-unit and the self-unit is adapted to be connected to the other units through the collected sound signal input-output terminal by means of transmission cables.
