Abstract
A multi-channel stereo speaker system includes acoustically separated but mechanically connected chambers containing active drivers to reproduce sound for each channel, and a passive radiator for each chamber to help tune the frequency response of the chamber. Passive radiators are positioned and oriented so that their movements tend to cancel each other out.
Claims20
A multi-channel loudspeaker comprising:
- an enclosure subdivided into a plurality of separate chambers;
- a plurality of active drivers, one active driver in each of the separate chambers;
- and
- a plurality of passive radiators, one passive radiator in each of the separate chambers, wherein
- the passive radiators are oriented so that physical movement of a first passive radiator in a first separate chamber is at least partially counterbalanced by physical movement of at least a second passive radiator in a second, different separate chamber.

A multi-channel loudspeaker comprising:
- an enclosure subdivided into a plurality of separate chambers;
- a plurality of active drivers, one active driver in each of the separate chambers;
- and
- means for passively tuning a resonant frequency of each of the separate chambers, wherein
- action of the means for passively tuning the resonant frequency of a first separate chamber opposes action of the means for passively tuning the resonant frequency of a second separate chamber.
2 more elements
A two-channel (stereo) loudspeaker comprising:
- a left-channel chamber with at least one left-channel active driver and at least one left-channel passive radiator;
- a right-channel chamber with at least one right-channel active driver and at least one right-channel passive radiator, wherein
- the left-channel chamber and the right-channel chamber are mechanically connected but acoustically separated;
- and
- directed centerlines of at least one left-channel passive radiator and at least one right-channel passive radiator are substantially coincident but oriented in opposite directions.
