Abstract
A speaker enclosure has three chambers sub-divided from one other, each chamber being ported by its own separate acoustic port to the ambient. An electro-acoustic transducer is mounted in communication with two of the chambers, and the third chamber being is isolated from the transducer except for an acoustic port communicating between the third chamber and one of the other two chambers.
Claims10
A loudspeaker system comprising:
- a) an enclosure means providing an interior having three acoustic chambers comprising a speaker housing and a first partition means and a second partition means, said first and second partition means subdividing said housing into a first acoustic chamber, a second acoustic chamber and a third acoustic chamber;
- b) an electro-acoustical transducing means for converting an input electrical signal into a corresponding acoustic output signal, said transducing means being mounted by said first partition means so that said first and second chambers are in direct acoustic communication with said transducing means;
- and
- c) port tube means providing a first port acoustically communicating said first chamber to the ambient, a second port acoustically communicating said second chamber to the ambient, a third port acoustically communicating said third chamber to the ambient, and a fourth port acoustically communicating either said first chamber or said second chamber to said third chamber, so that said third chamber is acoustically separated from direct acoustic communication with said transducing means and only indirectly communicated with said transducing means by way of said fourth port, and so that said third chamber is only communicated with one of said first and second chambers.
