Abstract

PURPOSE: To enlarge a reproducing band by providing an acoustic tube at the back of a speaker unit, and arranging an empty room, a port or a passive radiator in the front so as to constitute the speaker system of a phase inversion type.
CONSTITUTION: A partition board 6 provided inside a cabinet 5 constitutes the acoustic tube by a path from the back of the speaker unit 8 to an opening 7. The front of the speaker unit 8 constitutes the speaker system of a bass-reflex type by the empty room 9 and the port 10, and the resonance frequency of the port 10 and the idle room 9 is set so that the wave length is matched with length of the acoustic tube. Since a high voltage level can be obtained for the wide band, and the opening of the port 10 is provided inside the opening 7 of the acoustic tube, a sound source becomes one viewing from a sound field space, and a sound pressure distribution can be set to uniform irrespective of the frequency.
