PROBLEM TO BE SOLVED: To provide a speaker system and a speaker enclosure for outputting a sufficient low frequency component even when they are compact. SOLUTION: When a speaker 10 is driven, the vibration of cone paper is propagated into air in the speaker enclosure 20 and vibration parts 31, 32 are vibrated. The resonance frequency of the vibration parts 31, 32 is set to a desired value wherein the low sound frequency region is emphasized and the high sound frequency region is cut by adjusting the frequency characteristics of the speaker 10, volumes of sub chambers 23, 24, and the area and the mass of the vibration parts 31, 32. Moreover, since the resonance frequencies of the vibration parts 31, 32 can be differentiated by differentiating the volume ratio of the sub chambers 23, 24 and the area ratio and the mass ratio of the vibration parts 31, 32, a band pass characteristic with a width can be provided by overlapping the frequency characteristics of sound waves output from the vibration parts 31, 32.
