Abstract

PURPOSE:To generally increase efficiency over the wide band area of a low frequency sound while the resonance of an acoustic tube is continuously generated by constituting plural pieces of acoustic tubes having different lengths on the back face of a speaker unit and further providing a shared acoustic tube at an outlet. CONSTITUTION:Partition boards 6a-6h in a cabinet 5 are constituted of two acoustic tubes having different length continuously extended from the back face of a speaker unit 8 and a shared acoustic tube at these outlets. Under a frequency f1 that one wavelength tunes in the longer acoustic tube, the front face sound of the speaker unit 8 is inverted with a sound to be radiated from an opening 7 of the common acoustic tube and a large sound pressure trough is generated. The shorter acoustic tube can be of an arbitrary acoustic characteristic by selecting its length, for example, when a tube length is obtained that a 3/4 wavelength tunes in at f1 so as to offset the sound pressure trough of the longer acoustic tube, the reproducing band of a low sound area can be widely expanded.
