PURPOSE: A speaker system is provided to increase an output with a simple structure and to implement desired directivity. CONSTITUTION: A first speaker group(11) radiates a sound from a first sound radiating surface(G1) according to a first input from a signal input part(300) into a speaker system(10). A second speaker group(12) radiates a sound from a second sound radiating surface(G2) according to second input from the signal input part into the speaker system. The first sound and the second sound are generated from a common signal source and have different phases.
