Abstract

PURPOSE: To expand a low frequency band characteristic by a small-sized speaker box by providing first and second ports different in cavity resonance frequency for expanding the low frequency band characteristic on the one surface and the back plate of the speaker box.
CONSTITUTION: The sound pressure frequency characteristic of a speaker system is obtained by synthesizing the sound pressure frequency characteristics, obtained by a cavity resonance between the first and the second ports 5, 6 for expanding the low frequency band characteristic, with the different frequency characteristics, on the front face and the rear face of the speaker box 2, and the low frequency band characteristic is expanded in comparing with the sound pressure characteristic of a tightly closed box of the same volume. In case of the speaker system is installed in a listening room, and it is evaluated in an audition state, because the speaker system is installed at the corner of the room or the vicinity of a wall, it is auditioned as the composite sound of the sounds emitted from the front face and the rear face of the system. The sound from the rear face is expanded at its low frequency by the effect of the wall 7 and the floor 8 of the room, and the sense of a low pitched sound is expanded compared with an anechoic room.
