Abstract: An optimized moving-coil loudspeaker is described herein. The loudspeaker includes an acoustic-radiating diaphragm that is non-cylindrical shape. The diaphragm is a substantially-planar substrate having uniform density. A moving-coil assembly is coupled to the acoustic-radiating diaphragm. The assembly is configured to move back and forth in a linear fashion. As the assembly is connected to the diaphragm it causes acoustic waves to be emitted from a front surface the acoustic-radiating diaphragm. The acoustic-radiating diaphragm is not supported by a conventional basket, among other differences.

Abstract: Loudspeakers optimized for use in array environments are described herein. In one embodiment, a system includes a transducer-array module having a plurality of piston-based transducers. Each transducer is configured to drive a particular one of a plurality of discrete non-concentric acoustic-radiating diaphragms. A frame is positioned around an outermost boundary of a plurality of the discrete non-concentric acoustic-radiating diaphragms, which are adjacent to the outermost boundary. The transducer-array module may be used in array configurations, including, but not necessarily limited to: line, planar, and phased arrays.

Abstract: A audio enhancement system and method of use with a sound system for producing primary sound from at least one main loudspeaker located at a main position. The audio enhancement system comprises at least one wireless transmitter, time delay circuitry, and plural augmented sound producing subsystems. Each sound subsystem is a portable unit arranged to be carried by a person located remote from the main loudspeaker and includes a wireless receiver and an associated transduce device, e.g., a pair of stereo headphones. The transmitter broadcasts an electrical signal which is representative of the electrical input signal provided to the main loudspeaker. The broadcast signal is received by the receiver and is demodulated and amplified to drive the transducer so that it produces augmented sound substantially in synchronism with the sound arriving from the main loudspeaker.
