Abstract
In each sound unit, when connection with another sound unit is detected, an input control signal is supplied to a control section and then supplied to the adjoining sound unit. Input clock signal is supplied to a PLL section, and an output clock signal from the PLL section is supplied to the adjoining sound unit. Input speaker output signal and microphone input signal are supplied to a speaker output signal processing section and microphone input signal processing section, respectively. The speaker output signal processing section performs predetermined signal processing on an input signal to output the resultant processed signal to a speaker array, and then performs internal delay compensation processing on the signal to output the resultant processed signal to the adjoining sound unit. The microphone input signal processing section calculates a sum of the input signal and sums of delayed signals of outputs from the microphone array and then performs internal delay compensation processing on the signal to output the resultant processed signal to the adjoining sound unit.
