Abstract:
1. A speaker system, comprising: a first-transducer-array module containing a plurality of piston-based transducers each configured to drive a particular one of a plurality of discrete non-concentric acoustic-radiating diaphragms; and a first-retaining frame positioned around an outermost boundary of the plurality of the discrete non-concentric acoustic-radiating diaphragms, which are adjacent to the outermost boundary; wherein a peripheral edge of each one of the plurality of discrete non-concentric acoustic-radiating diaphragms is adjacent to the first-retaining frame or a peripheral edge of another one of the plurality of discrete non-concentric acoustic-radiating diaphragms; one or more flexible-joint structures joining the peripheral edge of each one of the plurality of discrete non-concentric acoustic-radiating diaphragms to the first-retaining frame or the peripheral edge of an adjacent one of the plurality of discrete non-concentric acoustic-radiating diaphragms; wherein each of the plurality of piston-based transducers is connected to a corresponding discrete non-concentric acoustic-radiating diaphragm, directly or indirectly, via a voice-coil former, and wherein no basket frame surrounds, joins, or is interposed between the peripheral edges of each of the plurality of discrete non-concentric acoustic-radiating diaphragms.
