Patent ID: 7021419

Claim:
A speaker system comprising: speaker units; and 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 unit mounted in an enclosure alone, wherein said sound radiation component has a front cavity defined in a fashion corresponding to a peripheral portion of said speaker unit and a port for guiding an acoustic wave radiated from the speaker unit to the free space, wherein said port has a width in an intermediate portion thereof which is smaller than those of a connection between the front cavity and the port and of an outlet portion thereof and has a planar shape that is asymmetrical with respect to the axis of the port in an acoustic wave guide-out direction, and wherein the speaker system has 20% or more lower f 0 than in the case where acoustic waves are directly radiated to the free space with the speaker unit mounted in the enclosure.
