MULTI-SPEAKER CONTROL APPARATUS, SPEAKER DEVICE, AND MULTI-PEAKER SYSTEM

PROBLEM TO BE SOLVED: To provide a technique capable of, when supplying audio data to a plurality of speaker devices, mutually connecting therebetween with more simplicity.SOLUTION: A multi-speaker control apparatus includes an interface section that generates a superposition signal by superposing an audio signal over a power signal, and an audio output terminal that guides the superposition signal to a speaker device by riding the superposition signal on one cable. The speaker device includes an interface section that inputs and outputs a superposition signal obtained by superposing an audio signal over a power signal, an amplifier that amplifies the audio signal, and a speaker that outputs the amplified audio signal.
