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.
