摘要： A specially designed ribbon for a ribbon loudspeaker is disclosed which prevents ribbon snaking associated with prior art corregated ribbon. The elimination of snaking enables the use of extremely small gaps between the side edges of the ribbon and the magnetic pole pieces which in turn greatly reduce transient distortion of high fidelity sound. Relatively large amplitude corregations are formed within suspended terminal ribbon portions and substantially smaller amplitude corregations are formed within the suspended centralized ribbon portion.

摘要： An acoustic transducer with a new kind of diaphragm geometry and a new kind of acoustical or vibratory excitation of the diaphragm. The diaphragm comprises a plurality of substantially equal spaced and substantially parallel diaphragm portions which define between themselves small air spaces, and means connecting the diaphragm portions to each other in such a manner so as to close each of the air spaces at three sides while the fourth side is left open and with the open sides of adjacent air spaces respectively facing in opposite directions. As a result of this arrangement, the narrow air spaces between adjacent diaphragm portions get alternatingly enlarged or reduced and alternatingly air is sucked in or expelled from the adjacent air spaces during vibration of the diaphragm portions. During each half-cycle of the vibration air is sucked in one direction into every second of the adjacent air spaces and expelled in the opposite direction from the other air spaces and during the next half-cycle the motion of air into and out of adjacent air spaces is reversed. Such diaphragm arrangement moves more air with less kinetic energy than conventional diaphragms. The vibratory diaphragm portions may be directly driven by applying an audio current, respectively an audio voltage to conductors attached to the diaphragm portions and located in a strong magnetic field, or the diaphragm portions may be indirectly driven by a pair of voice coils alternatingly attached to adjacent vibratory diaphragm portions to move the latter toward and away from each other. On the other hand, the vibratory diaphragm portions may be acoustically driven and audio currents, respectively audio voltages, may be produced in conductors attached to the diaphragm portions and moving in a strong magnetic field.
