Abstract
A small-sized speaker system having a very excellent bass-range reproduction capability includes a sound radiation component for guiding acoustic waves radiated from the speaker units to a free space by causing a larger degree of air compression and expansion than in the case where acoustic waves are directly radiated to the free space with the speaker units mounted in corresponding enclosures of the same shape as the speaker units. The speaker system has 20% or more lower fthan in the case where acoustic waves are directly radiated to the free space with the speaker units mounted in corresponding enclosures of the same shape as the speaker units.
