Electro-acoustic converte ris for at least upper hearing range and incorporates at least two small such converters

摘要

The electro-acoustic converter is for at least the upper hearing range and incorporates at least two small such converters. It is fitted along a bent line at the mouth of each small converter and with a distance between the centers of the small converters to be moved mechanically. The second wave which occurs is further bent by different input signals to each small converter. Six or more small converters can be used and are of the ring radiator or dome type, with a speech coil diameter of approximately three-quarters of an inch or approximately one inch and with an internal magnet (metric dimensions 1.91, 2.54 centimeters). Where single dimensional bending occurs, the sound can be controlled in the other dimensions traditionally by flanks (5).
